The postflight photograph was taken in the Orbiter Processing Facility during
the period when the LDEF was being transferred from the Orbiter cargo bay to
the KSC Payload Transporter.

The Biostack experiment appears to have survived the extended mission with no
visible damage.  The Kapton window covers for two (2) of the experiment
housings seem to be intact and all hardware is securely in place. The
once-white experiment housing is now coated with a light brown or tan stain.
The base plate and the tray sidewalls also have a thin coat of the stain on the
exposed surfaces. The vertical thermal isolation plateis secure with all
fasteners in place.

The postflight photograph was taken prior to the experiment tray being removed
from the LDEF. The tray corner clamp blocks are un-anodized aluminum and that
alone accounts for the major difference in color between the corner clamp
blocks and the center clamp blocks.

The MAP experiment, located in the left end of the integrated tray, shows signs
of contamination but otherwise seems intact. The mesh support, the detector
foils and the bond joints are intact and show no sign of physical failure.
There are some darker contamination stains in areas on the diecast aluminum
frames where adhesive residue remained after prelaunch cleaning. Some color
differences are observed when comparing this photograph to the prelaunch and
flight photographs.  These differences seem to be due to lighting direction and
intensity as well as colors of objects in the surrounding area.

The flight photograph was taken during the LDEF retrieval and provides an

visible around some of the fasteners and on mounting plates. The stain has been
attributed to outgassing and contamination from the LDEF and experiment related
materials being flown. When compared to the prelaunch photograph, the C09
integrated tray seems to be in excellent condition.

The MAP experiment die-cast aluminum frames, fasteners and polished aluminum
stop plate seem to be in excellent shape. The detector bond joints and foil
materials appear to be in-tact and have maintained thier integrity in all eight
visible stacks. The white color seen on some detector foils and also on the
polished aluminum stop plates between the detector stacks is a reflection of
the Orbiter's cargo bay liner in the metallic surfaces. The dark gray color of
the die-cast aluminum frames is thought to be caused by effects of the on orbit
lighting, direction and intensity.

The flight photograph was taken from the Orbiter aft flight deck during the
LDEF retrieval. During the mission, the tray surface was at an angle of
approximately ninety-eight (98) degrees to the orbital velocity vector and
therefore exposed to a lower atomic oxygen flux than if parallel with the
velocity vector. A very light stain is present on the white paint dots on
experiment tray clamps along the lower edge of the tray.

Changes to the MAP experiment die-cast aluminum frames, fasteners and polished
aluminum stop plate are difficult to detect. The die-cast frames have areas
where discoloration observed during the prelaunch inspection seem to be
darker. The detector bond joints and foil materials appear intact at all eight
visible stacks locations. The irregular white shape on the tray sidewall above
the experiment detector stack seems to be caused by the reflection of sunlight
from the aluminum base plate onto the tray sidewall. At the top edge of the
adjacent detector stack, the sunlight reflected from the top flange of the
die-cast aluminum frame on the detector foil material highlights the brass
mesh support. The four (4) detector stacks where the die-cast frames appear to
be a lighter color have the detector foil material and the brass support mesh
bonded to the far side of the frame, where as, the four (4) darker appearing
stacks have the detector foils and brass mesh bonded to the near side of the
frame.

Photo, Description==
The postflight photograph was taken in the SAEF-II facility prior to removal of
experiment trays from the LDEF. The Multiple Foil Microabrasion Package (MAP)
Experiment (AO023) experiment is located in the left one third (1/3rd) section,
the Balloon Materials Degradation Experiment (S1006)  occupies the center one
third (1/3rd) section, the Measurement of Heavy Cosmic-Ray Nuclei on LDEF
Experiment (M0002-2) is located in the lower one half (1/2) of the right
section and the Ion Beam Textured and Coated Surfaces Experiment (S1003) is
shown in the top right section of the tray. The tray flanges appear as
prelaunch but the white paint dots on tray clamp blocks have varying degrees of
discoloration. The paint color on the lower-center clamp block is white, paint
on the left-center clamp block is lightly discolored and paint on the top-right
clamp block is heavily discolored.

The MAP experiment consist of thin film detectors bonded to brass mesh supports
and the mesh support bonded to a die-cast aluminum frame. Three (3) stacks of
detectors have the detector foil and support mesh bonded to the out side of the
die-cast frame, those with the brass support mesh clearly visible, and five (5)
have the detector foil and support mesh on the inside. The die-cast aluminum
frames, stacked two (2) high, are placed over a polished aluminum stop plate
and the combined assembly is bolted to an aluminum mounting plate.

The MAP experiment has no visible damage, the die-cast aluminum frame, the
brass support mesh, the detector foils and the bond joints seem to be intact.
Discolorations on the die-cast frames with the detector and support material
adhesive joint beneath the frame appear darker post-flight. The die-cast frames
with the detector and support material on top of the frame have discolorations
on the frame and the brass mesh material. The discolorations appear along the
bond line between the support mesh and die-cast frame where the adhesive may
not have been completely cleaned from the surface during post assembly
cleaning. The bottom edge of the experiment baseplate is mirrored on the tray
sidewall. The other areas of the baseplate are shadowed and appear
darker.

The MAP experiment survived the mission with no apparent damage. The die-cast
aluminum frame, the brass support mesh, the detector foils and the bond joints
appear to be intact. Discolorations on the die-cast frames with the detector
and support material adhesive joint beneath the frame appear darker than in the
prelaunch photograph. The discolorations appear to be along the bond line
between the support mesh and die-cast frame where the adhesive may not have
been completely cleaned from the surface during post assembly cleaning.

The flight photograph was taken during the LDEF retrieval and provides an
on-orbit view of the C09 integrated tray. When comparing this photograph with
the prelaunch photograph, very little difference can be seen. A brown stain is
visible around some of the fasteners and on mounting plates. The stain has been
attributed to outgassing and contamination from the LDEF and experiment related
materials being flown. When compared to the prelaunch photograph, the C09
integrated tray seems to be in excellent condition.

The Atomic Oxygen Stimulated Outgassing experiment seems to have changed little
over the sixty nine (69) month LDEF mission. The experiment seems to be intact.
The grayish appearance of the experiment coverplate is thought to be the
results of lighting direction and intensity. The anodized aluminum disks,
located in the openings at the four corners, appear to be brighter than in the
pre-launch photograph. This is seems to be due to a reflection of the white
cargo bay liner in the disks.

The postflight photograph was taken prior to the experiment tray being removed
from the LDEF. The tray corner clamp blocks are un-anodized aluminum and that
alone accounts for the major difference in color between the corner clamp
blocks and the center clamp blocks.

The Atomic Oxygen Stimulated Outgassing experiment, seen in the top center tray
location, shows little change when compared with the pre-launch photographs if
lighting direction and intensity are considered. Experiment details are clearly
visible in the postflight photograph. For instance, the six (6) quartz windows
that fill openings in the cover plate, those with a pale gold tint, can be
located. Reflections of the photographic lights  can be seen on surfaces of the
specimen located in the cavities behind the cover plate. The aluminum disk,
filling each of the corner openings, are also more visible. A close inspection
of the photograph reveals a thin brown stain on the cover plate and
fasteners.

The postflight photograph was taken in the KSC SAEF II facility prior to

The brown stains are still very prominent but seem to be less vivid than in the
flight photograph.  This may be due to the different lighting intensity and
direction. The openings in the base plate for the grid voltage cable connectors
show clearly and are thought to be the source of the brown stains around the
connector. The beryllium copper collector foils are clearly visible in this
photograph as are the baffles near the top of the canister housing. However,
the fine wire mesh grid cannot be seen. Due to an experiment system
malfunction, the canister collector foils that are visible were exposed for the
total mission.

The flight photograph was taken from the Orbiter aft flight deck during the
LDEF retrieval. During the mission, the tray surface was at an angle of
approximately ninety-eight (98) degrees to the orbital velocity vector and
therefore exposed to a lower atomic oxygen flux than if parallel with the
velocity vector. A very light stain is present on the white paint dots on
experiment tray clamps along the lower edge of the tray.

The color of the white thermal control paint on the IGE has changed and now
varies from white to differing shades of brown. The darker brown areas on the
experiment baseplate, around the grid voltage cable connectors, appear to have
come  from contaminants flowing from inside the LDEF.  The shadows from the
tray sidewalls hide most of the dark stain in the upper right corner of the
tray. A lighter stain coats the tray's upper side wall, the left side of the
canister housing and the experiment baseplate. The insulation on the grid
voltage cable that was transparent prior to launch is now a light tan
color.

Photo, Description==
The prelaunch photograph provides a view of the Interstellar Gas Experiment
(IGE) hardware and shows the orientation of two (2) experiment canister
housings mounted in a twelve (12) inch deep peripheral tray. The experiment
utilizes seven (7) canisters containing high-purity beryllium copper
collecting foils, three (3) located in peripheral trays and four (4) located in
trays on the space end of the LDEF, to meet experiment objectives. The active
portion of the experiment consist of canister electronic timing devices and
pyrotechnic cutters that control the exposure time of each collector foil. An
electronic voltage multiplier system provides a bias voltage to the grid
network located above the beryllium copper collecting foils.The batteries and
the electronics are housed beneath the experiment baseplate facing the LDEF
interior.

The white painted surface area within the LDEF tray provides the optical
properties required to maintain the experiment components within temperature
limits. The two (2) rectangular openings in opposite corners of the experiment
baseplate provide the mountings for the ground support equipment test
connectors. A   white grid voltage connector box, mounted on the side of each
canister housing, provides the termination point for the cables running from
the grid voltage box beneath the baseplate. The canister housing is a welded
aluminum structure with aluminum mounting flanges. The experiment components
are assembled using non-magnetic stainless steel fasteners. The aluminum
housing cover, removed prior to flight, protects experiment components from
damage and large particle contamination during ground handling.

The flight photograph was taken from the Orbiter aft flight deck during the
LDEF retrieval. The OMS pod and a small part of the aft bulkhead in the
Orbiter's cargo bay can be seen along the left side of the photograph. The
three (3) black rectangles on the OMS pod are locations where thermal
protection tiles were lost during the Orbiters ascent to orbit. During the LDEF
mission, the F06 experiment tray surface was at an angle of approximately
eighty-two (82) degrees to the orbital velocity vector and therefore exposed to
a higher atomic oxygen flux than if parallel with the velocity vector. The
white paint dots and experiment tray clamps along the upper edge of the tray
appear to be clean. However, a brown stain is present on the white paint dots
and experiment tray clamps along the lower edge of the tray.

The color of the white thermal control paint on the IGE has changed from white
to differing shades of brown. The brown stain on the tray sidewalls and all
experiment hardware appears to be a product of contamination and the space
environment. A hand print, not visible in the prelaunch photograph, can be seen
on the baseplate in the lower half of the experiment tray. The white dot near
the lower corner of the end sidewall is a reflection of the GSE test connector
located in the lower left corner of the baseplate. The two (2) white dots on
the experiment baseplate, near the left end of the tray, appear to be
imperfections in the photograph since they were not observed during post-flight
inspection..The insulation on the grid voltage cable that was transparent prior
to launch is now a light tan color. The lighting and camera angle provide a
clear view of the baffles located interior  and near the upper edges of the
canister housing. The baffles seem to be relatively clean of the brown
contamination.

The postflight photograph was taken in the KSC SAEF II facility prior to
removing experiments from the LDEF.

The brown stains are still prominent and seem to be a little more intense than
in the flight photograph. This may be due to the different lighting intensity
and direction. The beryllium copper collector foil is clearly visible in this
photograph as are the baffles near the top of the canister housing. However,
the fine wire mesh grid  cannot be seen. Due to an experiment system mal-
function, the canister collector foil that is visible was exposed for the total
mission.

The prelaunch photograph provides a view of the Interstellar Gas Experiment
(IGE) hardware and shows a single experiment canister housing mounted in a
twelve (12) inch deep peripheral tray. The experiment utilizes seven (7)
canisters containing high-purity beryllium copper collecting foils, three (3)
located in peripheral trays and four (4) located in trays on the space end of
the LDEF, to meet experiment objectives. The active portion of the experiment
consist of canister electronic timing devices and pyrotechnic cutters that
control the exposure time of each collector foil. An electronic voltage
multiplier system provides a bias voltage to the grid network located above the
beryllium copper collecting foils.The batteries and the electronics are
housed beneath the experiment baseplate facing the LDEF interior.

The white painted surface area within the LDEF tray provides the optical
properties required to maintain the experiment components within temperature
limits. The rectangular opening in the upper right corner of the experiment
baseplate provide the mounting for the ground support equipment test connector.
The white grid voltage connector box, mounted on the side of the canister
housing, provides the termination point for the cables running from the grid
voltage box beneath the baseplate. The canister housing is a welded aluminum
structure with aluminum mounting flanges. The experiment components are
assembled using non-magnetic stainless steel fasteners. The aluminum housing
cover, removed prior to flight, protects experiment components from damage and
large particle contamination during ground handling.

The flight photograph was taken from the Orbiter aft flight deck during the
LDEF retrieval. A very light contamination stain is present on the experiment
tray flanges and on the most of the visible LDEF structure. The exception being
a much darker stain on the structure adjacent to thermal covers that provide
venting for the LDEF interior.  The paint dot, originally white, adjacent to
the thermal cover vent area is heavily coated with the brown contamination
stain while the paint dot adjacent to the center end cover plate has a very
light coating.

The color of the white thermal control paint on the IGE has changed and now
varies from offwhite to a dark brown. The darker brown areas on the
experiment baseplate, around the grid voltage cable connectors, appear to
have come from contaminants flowing from inside the LDEF.  A dark stain area
can be seen on the tray's lower sidewall but a shadow hides most of the dark
stain in the upper left corner of the tray. A lighter stain coats portions of
the experiment baseplate and the outside of the canister housing. A beryllium
copper collector foil is clearly visible in the lower left canister housing as
are the baffles and reflected light from the fine wire mesh grid near the top
of the canister housing. Due to an experiment system malfunction, the canister
collector foils that are visible were exposed for the total mission.

berthing in the Orbiter's cargo bay.  The paint dots on clamp blocks located at
the centers of the trays lower and left flanges and at the right end of the
upper flange have changed from their original white color to a dark brown.

The SP HVD experiment consist of two identical sets of experiment hardware
mounted in three (3) inch deep LDEF experiment trays, one tray is located in
the LDEF position B04 adjacent to the LDEF trailing edge and the other is
located at LDEF position D10 adjacent to the LDEF leading edge. Each set of
SP HVD experiment hardware, self-contained within the experiment tray, consist
of six (6) fiberglass reinforced epoxy modules carrying charged dielectric
samples on top and the power supplies and electronics below. Four (4)
dielectric samples, Kapton with Vapor Deposited Aluminum on one side
(VDA-Kapton), are bonded to each of the fiberglass modules with a silver filled
conductive epoxy. The spaces between the dielectric sample covered modules and
between the modules and the tray flanges are covered by strips of VDA-Kapton
attached with acrylic transfer adhesive and Kapton tape. Each experiment tray
also contain two solar cell modules. Power for the experiment is provided by
LiSO2 batteries supplied by the LDEF Project. The experiment was assembled
using non-magnetic stainless steel fasteners.

The SP HVD experiment appears to be intact with no apparent physical damage
from exposure to the space environment. The lighting is such that changes in
material colors is difficult to detect, however, the white paint in the
vicinity of the solar cell modules appears to have darkened.

The prelaunch photograph of The Space Plasma High Voltage Drainage Experiment
(SP HVD) was taken in SAEF II at KSC prior to installation on the LDEF.

The SP HVD experiment consist of two identical sets of experiment hardware
mounted in three (3) inch deep LDEF experiment trays, one tray is located in
the LDEF position B04 adjacent to the LDEF trailing edge and the other is
located at LDEF position D10 adjacent to the LDEF leading edge. Each set of
SP HVD experiment hardware, self-contained within the experiment tray, consist
of six (6) fiberglass reinforced epoxy modules carrying charged dielectric
samples on top and the power supplies and electronics below. Four (4)
dielectric samples, Kapton with Vapor Deposited Aluminum on one side
(VDA-Kapton), are bonded to each of the fiberglass modules with a silver filled
conductive epoxy adhesive. The spaces between the dielectric sample covered
modules and between the modules and the tray flanges are covered by strips of
VDA-Kapton attached with acrylic transfer adhesive and Kapton tape. Each
experiment tray also contain two solar cell modules. Power for the experiment
is provided by LiSO2 batteries supplied by the LDEF Project. The experiment was
assembled using non-magnetic stainless steel fasteners.

The Space Plasma High Voltage Drainage Experiment (SP HVD) flight photograph
was taken while the LDEF was attached to the Orbiter's RMS arm prior to
berthing in the Orbiter's cargo bay. The paint dots on clamp blocks located at
the center of the trays right flange and at the right and left ends of the
left flange have changed very little from their original white color.

The SP HVD experiment consist of two identical sets of experiment hardware
mounted in three (3) inch deep LDEF experiment trays, one tray is located in
the LDEF position B04 adjacent to the LDEF trailing edge and the other is
located at LDEF position D10 adjacent to the LDEF leading edge. Each set of

also contain two solar cell modules. Power for the experiment is provided by
LiSO2 batteries supplied by the LDEF Project. The experiment was assembled
using non-magnetic stainless steel fasteners.

The SP HVD experiment in this tray was severely degraded by impingement of
atomic oxygen during the long exposure to the space environment. Most of the
Kapton polyimide material making up the dielectric samples was completely
eroded leaving only the 2000-3000 angstrom vapor deposited aluminum layer
bonded to the module. The edges of the dielectric surface that survived were
taped over by Kapton tape with a silicone adhesive. The Kapton backing eroded
leaving the silicone adhesive that protected the Kapton surface beneath. The
VDA-Kapton strips used to cover spaces between the modules have degraded
substantially and only fragments of the vapor deposited aluminum layer remain
attached along the edges. The white paint around the outer edges of the solar
cell modules appears to have changed little. Impact craters are visible as
black or white specks in many locations on the degraded dielectric surfaces.
One of the most noticeable is in the dielectric surface in the upper right
corner.

The prelaunch photograph was taken in SAEF II at KSC prior to installation of
the integrated tray on the LDEF and shows the locations of three LDEF
experiments integrated into a three (3) inch deep LDEF peripheral tray.

The High-Performance Infrared Multilayer Filters and Materials Technology
Experiment (AO056) is comprised of forty-six (46) individual specimen divided
between two (2) experiment modules, one module in an integrated experiment tray
at tray location B08, this location, and a second module located in an
integrated experiment tray on the Earth end of the LDEF at tray location
G12.

The High-Performance Infrared Multilayer Filters and Materials Technology
Experiment is located in the upper right  corner, one sixth (1/6th), of the
integrated tray. The infrared filters and coating samples are contained in the
circular holders located in the left half of the module and the materials
technology samples are located in the right half. An anodized aluminum
substructure is used to raise the sample mounting plate to a level that
minimizes shadowing of experiment samples by the experiment tray sidewall.
The aluminum mounting plate and the multilayer filter and coating aluminum
sample holders were anodized prior to the experiment assembly and non-mag-
netic stainless steel fasteners were used  to assemble the experiment
hardware.

The  flight photograph of the Cascade Variable Conductance Heat Pipe Experiment
(CVCHPE) was taken while the LDEF was attached to the Orbiter's RMS arm prior
to berthing in the Orbiter's cargo bay. The white paint dots on the center
clamp blocks of the experiment trays right flange and lower flange appear to be
slightly discolored. The LDEF structure, top intercostal, has a dark brown
discoloration adjacent to the black thermal panel. Aluminum particles from the
degraded CVCHPE thermal blanket are also visible in this area.

The Cascade Variable Conductance Heat Pipe Experiment (CVCHPE) occupies a 6
inch deep LDEF peripheral experiment tray and consist of two series connected
variable conductance heatpipes, a black chrome solar collector panel and a
silvered Teflon radiator panel, a power source to support six thermistor-type
temperature monitoring sensors and actuations of two valves. Fiberglass
standoffs and internal insulation blankets thermally isolated the experiment
from the experiment tray and the LDEF interior. The outside of the CVCHPE,
except the collector and radiator panels, was covered with an aluminumized
Kapton multilayer insulation (MLI) blanket with an outer layer of 0.076 mm
thick Kapton. The two patches of thin film materials, part of an atomic oxygen
experiment (see S1001) by NASA GSFC, were attached to the cover of the external
thermal blanket with Kapton tape. The experiment was assembled and mounted in
the experiment tray with non-magnetic stainless steel fasteners.

The external CVCHPE materials have changed significantly. The Kapton on the
thermal blanket aluminized Kapton cover appears to be completely eroded, except
under Kel-F buttons used to secure the blanket, leaving only the very thin
vapor deposited aluminum coating as a cover. Parts of the aluminum coating
residue has moved to cover a portion of the black solar absorber panel and also
areas of the trays upper and lower flanges. The shadow on the tray lower flange
would indicate that the aluminum extends several inches out of the tray
envelope. One of the two thin film atomic oxygen experiment  patches is gone
and the other does not appear to be securely attached. The layer of Kapton tape
over the thin film strips appears to be eroded with only the adhesive
remaining. The remaining atomic oxygen experiment materials have changed colors
and most appear to be severely degraded. The silvered Teflon coating of the
radiator panel appears diffuse with a light brown discoloration over most of
the surface. The white, evenly spaced, discolorations along the vertical
centerline and across the top of the panel appear to be above counter sunk flat
head screws used to assemble the experiment. The black spots on the radiator
panel appear to be impact craters where the impact penetrated the Teflon
material and exposed the silver beneath to the atomic oxygen flux. Particles of
the degraded thermal blanket material appear to be adhered to the surface of
the radiator panel.

The postflight photograph was taken in the SAEF II at KSC prior to removal of
the experiment from the LDEF. The color of the white paint dots on the exper-
iment tray clamp blocks appear to be unchanged. The LDEF structure, the
intercostal on the right, has a dark brown discoloration adjacent to the black
Earth end thermal panel. Aluminum pieces of the degraded CVCHPE thermal cover
that were shown lodged in the vent area between the intercostal and the black
thermal panel in the flight photograph are gone.

The Cascade Variable Conductance Heat Pipe Experiment (CVCHPE) occupies a 6
inch deep LDEF peripheral experiment tray and consist of two series connected
variable conductance heatpipes, a black chrome solar collector panel and a
silvered Teflon radiator panel, a power source to support six thermistor-type

NASA GSFC, were attached to the cover of the external thermal blanket with
Kapton tape.  The experiment was assembled and mounted in the experiment tray
with non-magnetic stainless steel fasteners.

The external surface of the CVCHPE has changed from that observed in the flight
photograph.  The thin vapor deposited aluminum coating, left after the Kapton
eroded, is essentially gone with only fragments left near the edges of the
thermal blanket. Pieces of a layer of Dacron mesh (bridle vail) material, used
to separate the thermal cover from the thermal blanket and between thermal
blanket sheets of aluminized Kapton, are visible along the edges of the blanket
and near Kel-F buttons used to secure the blanket. A large fragment of the
material is folded over the left side of the radiator panel. The large area of
discoloration on the right side of the black solar absorber panel appears to be
approximately the same shape as the aluminum coating that covered the area in
the flight photograph. The orientation of the remaining thin film atomic oxygen
experiment patch would indicate that the patch is attached to the Dacron mesh
and that the attachment is very fragile. The layer of Kapton tape that covered
the ends of the thin film strips appears to be eroded with only the adhesive
remaining. The remaining strips of the atomic oxygen experiment materials
have changed colors and most appear to be severely degraded. The silvered
Teflon coating of the radiator panel appears diffuse with a light brown
discoloration over most of the surface. The white, evenly spaced,
discolorations along the horizontal centerline and along the edges of the panel
appear to be above counter sunk flat head screws used to assemble the
experiment. The black spots on the radiator panel appear to be impact craters
that penetrated the Teflon material and exposed the silver beneath to the
atomic oxygen flux. Particles of the degraded thermal blanket material that
appeared  to adhere to the surface of the radiator panel in the flight
photograph are gone.

Photo, Description==
The flight photograph was taken during the LDEF retrieval and provides an
on-orbit view of the C03 integrated tray. When comparing this photograph with
the pre-launch photograph, one of  the most noticeable changes is the brown
stain, attributed to outgassing and contamination, on the tray structure and
most aluminum surfaces of experiments within the tray.

The Atomic Oxygen Interaction with Solid Surfaces experiment has significantly
changed during the LDEF mission. The S13G-LO white paint has turned to a light
tan color with darker areas near the coverplate edges and above the polished
aluminum cover plate. The specimen material and thier substrate base seem to
have survived the space environment. The blue tint seen on the polished
aluminum cover plate and some of the specimen materials is attributed to
reflection of the sky.

AO114 - The Interaction of Atomic Oxygen with Solid Surfaces post-flight
photograph shows a significant change in the color of the white paint, S13G-LO.
The light tan color is consistant with the contamination stain seen on other
exposed surfaces on the trailing side of the LDEF. However, the darker stains
seen around the top edge of the polished aluminum cover in the flight
photographs are not visible in this photograph.  The material specimen remain
intact in thier mountings and seem to have survived exposure to the space
environment very well. The polished aluminum cover plate has darkened and seems
to have a duller finish than seen in the prelaunch photograph. This condition
is attributed to a coating of the brown contamination stain.

The prelaunch photograph shows the location of four LDEF experiments integrated
into a three (3) inch deep LDEF tray.

The Interaction of Atomic Oxygen With Solid Surfaces experiment is shown in the
lower center section of the tray. The surface viewed is a coverplate designed
to mask one-half (1/2) of a specimen overcoated on an optically flat disk.
The specimen materials include silver, germanium, lithium fluoride, niobium,
nickel, aluminum, carbon, silicon, gold, platinum and a few engineering
materials. Some materials for which the removal rate is high, such as carbon,
are solid disk. The large coverplate accommodates forty eight (48) specimen and
is coated with a white silicon paint, IITRI S13G-LO. The smaller coverplate is
an aluminum plate with a highly polished surface and covers sixteen (16)
specimen. The three (3) oblong slits to the right of the smaller coverplate are
inlets to the three (3) reflectometers mounted on the backside of the mounting
plate. Non-magnetic fasteners are used for all mechanical attachments.

The postflight photograph was taken prior to the experiment tray being removed
from the LDEF. The tray corner clamp blocks are un-anodized aluminum and that
alone accounts for the major difference in color between the corner clamp
blocks and the center clamp blocks.

AO114 - The Interaction of Atomic Oxygen with Solid Surfaces post-flight
photograph shows a little change in the color of the white paint, S13G-LO. A
very faint tan tint can be seen but only around the outside edges of the cover
plate and the outside ring of fasteners. The material specimen remain intact
in their mountings and seem to have survived exposure to the space environ-
ment very well. The polished aluminum cover plate has darkened and seems to
have a duller finish than seen in the pre-launch photograph. This condition
could be attributed to a very thin coating of the brown stain and or the
different photographic conditions, lighting and surroundings.

Photo, Description==
The flight photograph was taken during the LDEF retrieval and provides an
on-orbit view of the C09 integrated tray. When comparing this photograph with
the prelaunch photograph, very little difference can be seen. A brown stain is
visible around some of the fasteners and on mounting plates. The stain has been
attributed to outgassing and contamination from the LDEF and experiment related
materials being flown. When compared to the prelaunch photograph, the C09
integrated tray seems to be in excellent condition.

The Atomic Oxygen Interaction with Solid Surfaces experiment appears to have
changed significantly during the LDEF mission. The S13G-LO white paint is
seen to be gray in color, the polished aluminum cover plate is now white and
some of the specimen that were dark in the prelaunch photograph are now seen as
white. These changes are attributed to the effects of the direction and
intensity of the light source when the photograph was taken. The experiment
hardware, the specimen material and substrate seem to have no adverse effects
from the space environment.

the tensile material were included to provide a more accurate measurement of
mass loss due to environmental exposure. Some specimen were coated with sput-
tered-metal deposits, nickel with an overcoat of silicon dioxide, to evaluate
metals effectiveness in protecting the composites when exposed to atomic
oxygen.

The tensile specimen and larger rectangular shaped material samples are
assembled on an aluminum support plate, located in the top one third (1/3rd)
of the tray, with aluminum hold-down straps and non-magnetic stainless steel
fasteners. Twelve specimen, six composite located near the left edge and six
metal located near the right edge of the support plate, were late additions and

composite specimen are mounted in an aluminum base plate, in the center
section of the tray, and partially masked with a thin aluminum cover plate with
circular openings. Sidewall shadows on the experiment specimen are eliminated
by mounting the support plate on fiberglass standoffs.

The CMLSS experiment components located on the upper one third tray mounting
plate appear to be intact  and the mounting hardware secure. The outer edges of
the experiment support plate and some of the hold down straps are discolored

The flight photograph was taken from the Orbiter aft flight deck during the
LDEF retrieval and prior to berthing the LDEF in the Orbiter cargo bay.

The Space Exposure on Pyroelectric Infrared Detectors Experiment (AO135)
consist of twenty detectors of three different types of materials,
lithium-tantalate, strontium-barium-niobate and triglycine-sulfide. The
Pyroelectric infrered detector experiment is an integral part of the Active
Optical System Component Experiment (S0050) that contains 136 test specimen and
is located in a six (6) inch deep LDEF peripheral experiment tray. The
experiment tray is divided into six sections, each consisting of a 1/4 inch
thick chromic anodized aluminum base plate and a 1/16th inch thick aluminum hat
shaped structure for mounting the test specimen. The test specimen are typi-
cally placed in fiberglass-epoxy retainer strip assemblies prior to
installation on the hat shaped mounting structure.  Five of the six sections
are covered by a 1/8 inch thick anodized aluminum sun screen with openings that
allowed 56 percent transmission over the central region. Two subexperiments,
The Optical Materials and UV Detectors Experiment (S0050-001) consist of 15
optical windows, filters and detectors and occupies one of the trays six
sub-sections and The Optical Substrates and Coatings Experiment (S0050-02 )
that includes 12 substrates and coatings and a secondary experiment, The
Holographic Data Storage Crystal Experiment (AO044) with four crystals, are
also mounted in the integrated tray. The experiment structure was assembled
with non-magnetic stainless steel fasteners.

The experiment hardware appears to be intact with no apparent damage. The
excess blue color in the photograph makes a detailed assessment of color
changes difficult. The paint dots on the tray clamp blocks, initially white,
appear to have darkened and tray flanges appear discolored. The experiment sun
screens and base plate also appear discolored. The exposed experiment test
specimen and their fiberglass-epoxy mountings appear to have survived the
mission with minimum degradation.

Photo, Description==
The postflight photograph was taken in SAEF II at KSC after the integrated
experiment tray was removed from the LDEF and the sun screens removed.

The Space Exposure on Pyroelectric Infrared Detectors Experiment (AO135)
consist of twenty detectors of three different types of materials,
lithium-tantalate, strontium-barium-niobate and triglycine-sulfide. The
Pyroelectric infrered detector experiment is an integral part of the Active
Optical System Component Experiment (S0050) that contains 136 test specimen and
is located in a six (6) inch deep LDEF peripheral experiment tray. The
experiment tray is divided into six sections, each consisting of a 1/4 inch
thick chromic anodized aluminum base plate and a 1/16th inch thick aluminum hat
shaped structure for mounting the test specimen. The test specimen are typi-
cally placed in fiberglass-epoxy retainer strip assemblies prior to
installation on the hat shaped mounting structure.  Five of the six sections
are covered by a 1/8 inch thick anodized aluminum sun screen with openings that
allowed 56 percent transmission over the central region. Two subexperiments,
The Optical Materials and UV Detectors Experiment (S0050-01) consist of 15
optical windows, filters and detectors and occupies one of the trays six
sub-sections and The Optical Substrates and Coatings Experiment (S0050-02 )
that includes 12 substrates and coatings and a secondary experiment, The
Holographic Data Storage Crystal Experiment (AO044) with four crystals, are
also mounted in the integrated tray. The experiment structure was assembled
with non-magnetic stainless steel fasteners.

The experiment hardware appears to be intact with no apparent damage. A brown
discoloration is clearly visible on the tray flanges. The location of
experiment test specimen and their mountings are shown in this photograph. The
fiberglass-epoxy mounting strip colors vary from the typical greenish-gray to a
slate gray in proportion to their exposure. The red material on top of the
aluminum support structure is a silicone rubber gasket between the sun screen
and the structure. The gasket material missing adhered to the sun screens.

The flight photograph was taken from the Orbiter aft flight deck during the
LDEF retrieval prior to berthing the LDEF in the Orbiter cargo bay and shows
the Solar Array Materials Passive LDEF Experiment (SAMPLE) on the LDEF. Six (6)
plates of passive components, provided by various experiment organizations and
designated plate I thru plate VI, are shown mounted in a three (3) inch deep
LDEF peripheral tray. All six plates are aluminum and attach to the LDEF
experiment tray with non-magnetic stainless steel fasteners.

Plate I, located in the upper left corner, consist of a combination of solar
cells with and without covers, solar cell modules and solar arrays assembled on
the baseplate.  Two of the four solar arrays are missing and one appears to be
attached at only one corner.  Other components appear to be secure. Plate II in
the left center section, has twenty-seven (27) composite samples, carbon fiber
and glass fiber, mounted on the baseplate.  The composites appear to be intact
with no physical damage. Plate III, in the lower left corner, consist mostly
of metallized and thin polymeric films (Kapton, Mylar, Teflon , white
Tedlar,etc.). The thin films without protective coatings sustained
significant damage and most were destroyed. The metallized film apparently
survived with minimum damage. Plate IV located in the upper right corner
consist of metals and coatings mounted in an aluminum baseplate and covered
with a thin aluminum coverplate that partially mask the specimen. Several of
the coatings appear to have changed to a darker color and a light brown

Photo, Description==
The post flight photograph was taken in the SAEF II at KSC prior to removal of
the experiment tray from the LDEF and shows the Solar Array Materials Passive
LDEF Experiment (SAMPLE) on the LDEF. Six (6) plates of passive components,
provided by various experiment organizations and designated plate I thru plate
VI, are shown mounted in a three (3) inch deep LDEF peripheral tray. All six
plates are aluminum and attach to the LDEF experiment tray with non-magnetic
stainless steel fasteners.

 Plate I, located in the upper right corner, consist of a combination of solar
cells with and without covers, solar cell modules and solar arrays assembled on
the baseplate.  Three of the four solar arrays are missing. Other components
appear to be secure. Plate II in the top center section, has twenty seven (27)
composite samples, carbon fiber and glass fiber, mounted on the baseplate.  The
composites appear to be intact  with no physical damage. Plate III, in the
upper left corner, consist of metallized and thin polymeric films (Kapton,
Mylar, Teflon , white Tedlar,etc.). The thin films without protective coatings
sustained significant damage and most were destroyed. The thin film specimen
hanging by one end in the flight photograph is missing. The metallized film
apparently survived the mission with minimum damage. Plate IV located in the
lower right corner consist of metals and coatings mounted in an aluminum
baseplate and covered with a thin aluminum coverplate that partially mask the
specimen. Several of the coatings appear to have darkened and a unique pattern
of light brown discoloration appears around the outer edges of the mounting
plate and along the lower edge of the coverplates. Plate V, in the lower center
section, contained thermal plastics and structural film configured into
tensile and shear specimen. All specimen, including the tape holding down the
small specimen in the lower right corner, have darkened significantly during
the extended time in space. Plate VI, in the lower left corner, is populated
with solar cells and associated components such as covers,
encapsulants,adhesives, etc. The solar cell components appear to be intact with
no apparent physical damage.The colors of the specimen, however, appear to
have darkened. The photographic lighting angle has significantly highlighted
abrasions on the mounting plate surface.

The postflight photograph of the integrated tray (D02) was taken in the
Operations and Checkout (O&C) building after the LDEF was transferred from
the KSC Payload Canister to the LDEF Assembly and Transport System (LATS). The
Radiation on Glasses experiment contains sixty-eight (68) cylindrical disc
glass samples mounted in Teflon retainers and installed on an aluminum mounting
plate. The aluminum mounting plate is painted with Chemglaze II A-276 white
paint to maintain the samples within acceptable thermal limits. The mounting
plate is attached to an adapter structure that raises the samples to a height
in the tray that minimizes shadowing from the tray sidewalls. The fasteners are
non-magnetic stainless steel.

The Radiation on Glasses experiment appears to be intact with little if any
impact damage. One impact crater is seen, as a white dot, on the mounting plate
to the right of the third row of samples from the bottom. The brown colored
surface, originally white, does not seem to have changed from the flight
photograph.

The Graphite-Polyimide and Graphite-Epoxy Mechanical Properties experiment
postflight photograph was taken in the Orbiter Processing Facility during the
period when the LDEF was being transferred from the Orbiter cargo bay to the
KSC Payload Transporter.  The photograph shows considerably more detail than
the flight photograph.  The horizontal lines on the honeycomb panel that appear
to be cracks from space exposure are instead fine lines of excess epoxy resin
formed during the bagging and curing process.  The harsh white color of the
epoxy adhesive along the rivet lines is from the lighting conditions in the
OPF.  The brown discoloration on the paint dots and the stain on the aluminum
mounting strips appear to have changed little from the flight photograph.  The
greater detail does show that a stain exists at most composite and mounting
strip interfaces.

Photo, Description==
The prelaunch photograph of the Ultra Heavy Cosmic Ray Experiment (UHCRE) was
taken in SAEF II at KSC prior to installation of the experiment tray on the
LDEF.

The UHCRE detectors were contained in 16 peripheral LDEF trays with at least
one UHCRE tray located on each row of the LDEF except row 3, row 9 and row 12.
Each tray contains three cylindrical aluminum pressure vessels with an
integral aluminum support structure. Each cylinder is filled with an Eccofoam
insert that houses 4 UHCRE detector stacks. Each stack consist of layers of
Lexan polycarbonate sheets (approximately 70) interleaved with several thin
sheets of lead.  Forty-seven of the 48 pressure vessels were pressurized to 1.0
bar with a dry gas mixture (oxygen, nitrogen and helium) and sealed. One of the
units was left unsealed in order to investigate the effects of the vacuum
environment on the detector materials. Thermal control was accomplished by
attaching an aluminized Kapton thermal cover on the tray bottom (the Kapton
facing the LDEF interior), placing the aluminum cylinder support structure on
thermal isolators and covering the experiment with a thin (5 mil) silvered
Teflon thermal cover. The silvered Teflon cover was supported by an aluminum
frame,  an integral part of the experiment structure, and held in place by
Velcro pads selectively located on the frame and on the back of the cover. The
copper colored strip extending over the trays lower flange is a copper coated
pressure sensitive tape used to provide an electrical ground between the
experiments thermal cover and the LDEF structure.

The postflight photograph of the Ultra Heavy Cosmic Ray Experiment (UHCRE) was

The white paint dot on the experiment tray clamp blocks located at the center
of the trays upper and right flanges and at the left end of the trays lower
flange appear to be discolored by a brown stain. The experiment tray flanges
also appear to be coated but with a lighter colored stain.

thermal cover to the support frame and appear more visible than in the
prelaunch photograph. The scallop effect around the cover edges occurs between
the cover attach points and shows the upper edge of the support frame. The
ground strap appears to be in place with no visible damage but is a darker

detectors are shown mounted in the experiment tray with the frame for
mounting the thermal cover in the foreground. The white rectangles on the frame
are Velcro pads bonded to the frame for attaching the thermal cover  and appear
in excellent condition. The top half of the cylinders and the thermal cover
frame were painted black to meet thermal control requirements.

visible in the upper right quadrant of the thermal cover.  The dark
discoloration is probably the results of an impact penetration of the 5 mil
Teflon film allowing atomic oxygen to oxidize and erode the vapor deposited
silver layer beneath. White dots of varying sizes can be seen on the cover,
many appear to be encircling impact craters. The cover is not stretched as taut
as in the flight photograph and locations of Velcro attach pads are not as
prominent.  The ground strap appears to be in place with no visible damage but
appears to be a deeper copper color.

one UHCRE tray located on each row of the LDEF except row 3, row 9 and row 12.
Each tray contains three cylindrical aluminum pressure vessels with an
integral aluminum support structure. Each cylinder is filled with an Eccofoam
insert that houses 4 UHCRE detector stacks. Each stack consist of layers of
Lexan polycarbonate sheets (approximately 70) interleaved with several thin
sheets of lead.  Forty-seven of the 48 pressure vessels were pressurized to 1.0
bar of a dry gas mixture (oxygen, nitrogen and helium) and sealed. One of the
units was left unsealed in order to investigate the effects of the vacuum
environment on the detector materials. Thermal control was accomplished by
attaching an aluminized Kapton thermal cover on the tray bottom (the Kapton
facing the LDEF interior), placing the aluminum cylinder support structure on
thermal isolators and covering the experiment with a thin (5 mil) silvered
Teflon thermal cover. The silvered Teflon cover was supported by an aluminum
frame,  an integral part of the experiment structure, and held in place by
Velcro pads selectively located on the frame and on the back of the cover. The
copper colored strip extending over the trays lower flange is a copper coated
pressure sensitive tape used to provide an electrical ground between the
experiments thermal cover and the LDEF structure.

The UHCRE thermal cover appears to be specular and intact with no apparent
damage. The cover appears less taut than in the flight photograph and the
locations of Velcro attach pads are not as prominent.  The scallop effect
around the cover edges occurs between the cover attach points and shows the
upper edge of the support frame. The ground strap appears to be in place with
no visible damage.

The  flight photograph of the Ultra Heavy Cosmic Ray Experiment (UHCRE) was
taken while the LDEF was attached to the Orbiter's RMS arm prior to berthing in
the Orbiter's cargo bay. The white paint dots on the center clamp blocks of the
experiment trays left flange and lower flange appear to be slightly discolored
but the paint dot on the clamp block located at the right end of the upper
flange appears to be stained less.

The UHCRE detectors were contained in 16 peripheral LDEF trays with at least
one UHCRE tray located on each row of the LDEF except row 3, row 9 and row 12.
Each tray contains three cylindrical aluminum pressure vessels with an
integral aluminum support structure. Each cylinder is filled with an Eccofoam

The UHCRE thermal cover appears to be intact with no apparent damage but is
stretched more taut than in the prelaunch photograph. The dark blue appearance
of the thermal cover in this photograph is apparently due to lighting
conditions and not a change in the material optical properties. The oblong
indentations on the dark thermal cover background are areas where Velcro pads
are bonded to the backside of the cover. The thermal covers surface appears to
have small  brown circular discolorations of various sizes that appear to be
impact craters. An impact crater surrounded by a large light blue area of
discoloration is clearly visible in the lower right quadrant of the thermal
cover. The discoloration is probably the results of an impact crater
penetrating the 5 mil Teflon film and upsetting the vapor deposited silver
layer beneath. The scalloped edge effect along the left side of the thermal
cover occurs between attach points. The ground strap appears to be in place
with no visible damage but appears to be a deeper copper color than in the
prelaunch photograph.

impact craters. Many of the craters appear to have a black center encircled by
a brown halo and then by a white halo. Other white circular discolorations
also appear on the cover surface. The darker  discolorations are probably the
results of an craters penetrating the 5 mil Teflon film allowing atomic oxygen
to oxidize and/or erode the vapor deposited silver layer beneath. An item of
interest is the impact crater in the lower right corner of the cover that has a
spray pattern originating from the point of impact. The cover is not stretched
as taut as in the flight photograph and locations of Velcro attach pads are not
as prominent.  The ground strap appears to be in place with no visible damage
but appears to be a deeper copper color.

Each tray contains three cylindrical aluminum pressure vessels with an
integral aluminum support structure. Each cylinder is filled with an Eccofoam
insert that houses 4 UHCRE detector stacks. Each consisting of layers of Lexan
polycarbonate sheets (approximately 70) interleaved with several thin sheets of
lead.  Forty-seven of the 48 pressure vessels were pressurized to 1.0 bar of a
dry gas mixture (oxygen, nitrogen and helium) and sealed. One of the units was
left unsealed in order to investigate the effects of the vacuum environment on
the detector materials. Thermal control was accomplished by attaching an
aluminized Kapton thermal cover on the tray bottom (the Kapton facing the LDEF
interior), placing the aluminum cylinder support structure on thermal isolators
and covering the experiment with a thin (5 mil) silvered Teflon thermal cover.
The silvered Teflon cover was supported by an aluminum frame,  an integral
part of the experiment structure, and held in place by Velcro pads selectively
located on the frame and on the back of the cover. The copper colored strip
extending over the trays lower flange is a copper coated pressure sensitive
tape used to provide an electrical ground between the thermal cover and the
LDEF structure.

The  flight photograph of the Ultra Heavy Cosmic Ray Experiment (UHCRE) was
taken while the LDEF was attached to the Orbiter's RMS arm prior to berthing in
the Orbiter's cargo bay. The white paint dots on the center clamp block of the
experiment trays upper flange and the right end of the experiment trays lower
flange appear to be slightly discolored. The tray flanges appear to be
discolored by a light brown stain and the ground strap located in the center of
the lower flange appears intact but a much darker copper color than in the
prelaunch photograph.

The UHCRE detectors were  contained in 16 peripheral LDEF trays with at least
one UHCRE tray located on each row of the LDEF except row 3, row 9 and row 12.
Each tray contains three cylindrical aluminum pressure vessels with an
integral aluminum support structure. Each cylinder is filled with an Eccofoam

attaching an aluminized Kapton thermal cover on the tray bottom (the Kapton

Velcro pads selectively located on the frame and on the back of the cover. The
copper colored strip extending over the trays lower flange is a copper coated
pressure sensitive tape used to provide an electrical ground between the
experiments thermal cover and the LDEF structure.

The UHCRE thermal covers surface appears to have changed from specular to
opaque (glossy white) marked with many black dots of various sizes that appear
to be impact craters. Many of the craters appear to have a black center
encircled by a brown halo. The cover appears to be stretched more than in the
prelaunch photograph with the locations of Velcro attach pads showing as oblong
indentations in the thermal cover.

The postflight photograph of the Ultra Heavy Cosmic Ray Experiment (UHCRE) was
taken in SAEF II at KSC after removal of the experiment tray from the LDEF. The
experiment tray flanges appear discolored by a light brown stain. Outlines of
experiment tray clamp blocks are faint but visible on the upper and lower
experiment tray flanges.The experiment tray holding fixture hardware covers
the clamp block areas on the end flanges.

The UHCRE detectors were  contained in 16 peripheral LDEF trays with at least
one UHCRE tray located on each row of the LDEF except row 3, row 9 and row 12.
Each tray contains three cylindrical aluminum pressure vessels with an
integral aluminum support structure. Each cylinder is filled with an Eccofoam

The UHCRE thermal covers surface appears to have changed from specular to
opaque with many black dots of various sizes that appear to be impact craters.
Many of the craters appear to have a black center encircled by a brown halo and
then by a white halo. Other white circular discolorations also appear on the
cover surface. The darker discolorations probably result from an impact that
penetrates the 5 mil Teflon film and allows atomic oxygen to oxidize and/or
erode the vapor deposited silver layer beneath. The black feather shaped
discoloration in the lower center of the thermal cover did not appear in the
flight photograph and appears to be a particle from a degraded experiment that
has attached itself to the cover. The cover is not stretched as taut as in the
flight photograph and locations of Velcro attach pads are not as prominent.
The ground strap appears to be in place with no visible damage but appears to
be a deeper copper color.

Photo, Description==
The  flight photograph of the Ultra Heavy Cosmic Ray Experiment (UHCRE) was
taken while the LDEF was attached to the Orbiter's RMS arm prior to berthing in
the Orbiter's cargo bay. The white paint dot on the center clamp block of the
experiment trays upper flange appears to be in prelaunch condition but the
paint dot on the clamp block located at the right end of the lower flange
appears to be slightly discolored.

The UHCRE detectors were  contained in 16 peripheral LDEF trays with at least
one UHCRE tray located on each row of the LDEF except row 3, row 9 and row 12.
Each tray contains three cylindrical aluminum pressure vessels with an
integral aluminum support structure. Each cylinder is filled with an Eccofoam
insert that houses 4 UHCRE detector stacks. Each stack consist of layers of
Lexan polycarbonate sheets (approximately 70) interleaved with several thin
sheets of lead.  Forty-seven of the 48 pressure vessels were pressurized to 1.0
bar of a dry gas mixture (oxygen, nitrogen and helium) and sealed. One of the
units was left unsealed in order to investigate the effects of the vacuum
environment on the detector materials. Thermal control was accomplished by
attaching an aluminized Kapton thermal cover on the tray bottom (the Kapton
facing the LDEF interior), placing the aluminum cylinder support structure on
thermal isolators and covering the experiment with a thin (5 mil) silvered
Teflon thermal cover. The silvered Teflon cover was supported by an aluminum
frame,  an integral part of the experiment structure, and held in place by
Velcro pads selectively located on the frame and on the back of the cover. The
copper colored strip extending over the trays lower flange is a copper coated
pressure sensitive tape used to provide an electrical ground between the
experiments thermal cover and the LDEF structure.

The UHCRE thermal cover appears to be intact with no apparent damage and is
taut. The blue appearance of the thermal cover in this photograph is apparently
due to lighting conditions and not a change in the material optical properties.
The oblong indentations in the thermal cover surface are areas where Velcro
pads are bonded to the backside of the cover. The thermal covers surface
appears to have small  light blue circular discolorations of various sizes that
appear to be points of impacts. The white irregular shapes in the photograph
appear to be light reflections from the edges of indentations in the cover
surface. The scalloped edge effect along the left side of the thermal cover
occurs between attach points. The ground strap appears to be in place with no
visible damage but appears to be a deeper copper color than in the prelaunch
photograph.

Photo, Description==
The postflight photograph of the Ultra Heavy Cosmic Ray Experiment (UHCRE) was
taken in SAEF II at KSC after removal of the experiment tray from the LDEF. The
experiment tray flanges appear to be discolored by a light brown stain. An
outline of experiment tray clamp block locations is clearly visible on the
experiment trays upper flange and to a lesser extent on its lower flange. The
holding fixture hardware covers the clamp block areas on the end flanges.

The UHCRE detectors were  contained in 16 peripheral LDEF trays with at least
one UHCRE tray located on each row of the LDEF except row 3, row 9 and row 12.
Each tray contains three cylindrical aluminum pressure vessels with an
integral aluminum support structure. Each cylinder is filled with an Eccofoam

copper colored strip extending over the trays lower flange is a copper coated
pressure sensitive tape used to provide an electrical ground between the
experiments thermal cover and the LDEF structure.

The UHCRE thermal covers surface appears specular with green and white
discolorations associated with  photo lights and reflections of the
surrounding area. The black and/or brown dots of various sizes appear to be
points of impact and penetration of the Teflon cover. The impact point
discoloration is probably the results of a penetration in the 5 mil Teflon film
that affected the vapor deposited silver and inconel layers beneath.. The cover
is not as taut as in the flight photograph and locations of the Velcro attach
pads are not as prominent. The ground strap appears to be intact with no
visible damage but appears to be a darker copper color than in the prelaunch
photograph.

The postflight photograph was taken in the SAEF II at KSC after the experiment
was removed from the LDEF.

The UHCRE detectors were  contained in 16 peripheral LDEF trays with at least
one UHCRE tray located on each row of the LDEF except row 3, row 9 and row 12.
Each tray contains three cylindrical aluminum pressure vessels with an
integral aluminum support structure. Each cylinder is filled with an Eccofoam
insert that houses 4 UHCRE detector stacks. Each stack consist of layers of
Lexan polycarbonate sheets (approximately 70) interleaved with several thin
sheets of lead.  Forty-seven of the 48 pressure vessels were pressurized to 1.0
bar of a dry gas mixture (oxygen, nitrogen and helium) and sealed. One of the
units was left unsealed in order to investigate the effects of the vacuum
environment on the detector materials. Thermal control was accomplished by
attaching an aluminized Kapton thermal cover on the tray bottom (the Kapton
facing the LDEF interior), placing the aluminum cylinder support structure on
thermal isolators and covering the experiment with a thin (5 mil) silvered
Teflon thermal cover. The silvered Teflon cover was supported by an aluminum
frame,  an integral part of the experiment structure, and held in place by
Velcro pads selectively located on the frame and on the back of the cover. The
copper colored strip extending over the trays lower flange is a copper coated
pressure sensitive tape used to provide an electrical ground between the
experiments thermal cover and the LDEF structure.

The UHCRE thermal cover appears to be specular and intact. The circular damaged
locations that appeared to to be impact points in the flight photograph  are
not as apparent in the reflections and is less taut cover. The wrinkled spots
on the thermal cover are areas where Velcro pads are bonded to the backside of
the cover. The scalloped effect around the cover edges occurs between the cover
attach points. The ground strap appears to be in place with no visible damage,
but it appears darker.

The postflight photograph was taken in the SAEF-II facility prior to removal of
experiment trays from the LDEF.

The Polymer Matrix Composite Materials experiment appears the same as in the
flight photograph. The composite containing the aramid (Kevlar) fibers has
changed from a yellow to a light brown color and the cylinderical tubes
containing the boron and carbon fiber materials have changed from a light green
tint to a brown color. The experiment mounting hardware and fasteners seem to
be intact and in very good condition.

The flight photograph was taken from the Orbiter aft flight deck during the
LDEF retrieval. During the mission, the tray surface was at an angle of
approximately ninety-eight (98) degrees to the orbital velocity vector and
therefore exposed to a lower atomic oxygen flux than if parallel with the
velocity vector. A very light stain is present on white paint dots on
experiment tray clamps along the lower edge of the tray.

The Polymer Matrix Composite Materials experiment has several changes to
material colors. The composite containing the aramid (Kevlar) fibers has
changed from a yellow to a light brown color and the cylindrical tubes
containing the boron and carbon fiber materials have changed from a light green
tint to a brown color.

The prelaunch photograph shows the positions of the three (3) LDEF
experiments in a three (3) inch deep tray. The AO023 experiment is located in
the left one third (1/3rd) section, the AO180 experiment occupies the center
one third (1/3rd) section plus the lower one half (1/2) of the right section
and the AO019 experiment is shown in the top right section of the tray.

The Polymer Matrix Composite Materials experiment is an active experiment that
occupies one half (1/2) of the tray's exposed surface area and contains a data
acquisition and recording system.  The experiment consist of sixty-two (62)
composite tubes with aluminum end fittings, forty-five (45) flat composite
coupons with aluminum retainer blocks, and one (1) stainless steel calibration
tube. The fasteners used to assemble the experiment were non-magnetic stainless
steel. The test samples were manufactured from different epoxy matrix
composites containing carbon, boron and aramide (Kevlar) reinforcements. A
custom data acquisition system was designed to record and store the data from
sixteen (16) thermal/strain gauges on a magnetic tape cassette. The data system
and batteries to power the system are located beneath the aluminum base
plates.

The experiment is shown in the postflight configuration before closing the
canisters with ground support equipment that bypassed the experiments onboard
electronics circuitry. Three full panels and approximately 3/4th of the other
panel are covered with gold foil (>99.99 percent pure). The remaining area on
the fourth panel is covered with strips of other detector materials:
zirconium, beryllium, titanium, platium, aluminum, carbon, Kapton,
polyethylene and Teflon.  A brown stain is visible on the experiment tray
flanges, however, most of the stains observed in the flight photograph are
obscured by reflected light. All materials remain intact with no visual
evidence of damage to the experiment. The reflection of a video camera on a
tripod and light sources can be seen on the gold foil covered panels.

The experiment canisters are shown after being closed by using the experiments
ground support equipment. The stain buildup can be clearly seen at the vertical
center of the right tray flange. The clean area was located under the
experiment tray clamp block and was not exposed to the staining medium. The
stain also coats other areas that were exposed during the mission but are not
as noticeable. The experiment hardware seems to be intact and have no
damage.

The flight photograph was taken with the LDEF on the Orbiter's RMS arm prior to
berthing the spacecraft in the cargo bay. The canisters are in their open
condition (they were expected to open about two (2) weeks after launch and
close about eleven (11) months into the mission) with three (3) full panels and
3/4th of the fourth panel covered with a highly reflective gold foil (>99.99
percent pure).The remaining area is covered with strips of other detector
materials:  zirconium, beryllium, titanium, platium, aluminum, carbon, Kapton,
polyethylene and Teflon. The exposed fasteners are non-magnetic stainless
steel.  All of the exposed materials seem to be secure and no damage is
evident. The contamination stain that has changed the white paint dot on the
tray clamp blocks to brown also coats the tray flanges and the aluminum
canister hardware. The end support beam scuff plate in the photograph was a
bright yellow prior to launch but is a much darker, mustard yellow after the
space exposure.

The Chemistry of Micrometeoroid Experiment (CME) flight photograph was taken
while the LDEF was attached to the Orbiter's RMS arm prior to berthing in the
Orbiter's cargo bay and shows six (6) aluminum detector plates mounted in a
three(3) inch deep LDEF peripheral experiment tray. The plates are unprotected
and are exposed to the total mission environment, ground handling as well as
flight. Non-magnetic stainless steel fasteners are used to attach the plates in
the LDEF provided experiment tray.

The experiment appears to be in good shape with all hardware intact. Impact
craters, that appear as small white imperfections in the dark blue background,
can be seen on all six (6) detector plates. The apparent dark blue color of the
aluminum detector panels in this photograph is the result of the lighting,
reflections on the panels and the camera angle.

trailing edge of the LDEF, was not exposed to the ram effects of the atomic
oxygen, still only one (1) of the forty (40) capture cell metallized Mylar
covers survived the total mission. The intact capture cell is located on the
lower support panel and is in the center of the right hand row of cells. At
other cell locations, pieces of the failed metallized Mylar capture cell cover,
curled into a tight conical shape, are seen adhering to the edges of the
aluminum mounting frame. The four (4) germanium plate outlines are visible at
locations where the cell cover material failed. Non-magnetic stainless steel
fasteners attach the aluminum frame to the support structure. The faint brown
tint on the aluminum frame is the result of contamination buildup.

The flight photograph was taken while the LDEF was attached to the Orbiter's
RMS arm, seen along the left side of the photograph, and provides an on-orbit
view of the C02 integrated tray. When comparing this photograph with the pre-
launch photograph, one of the most noticeable changes is the brown stain,
attributed to outgassing and contamination, on the experiment hardware within
the tray.

The experiment capture cells have been severely degraded by exposure to the
space environment even though the experiment, located in tray C02 near the
trailing edge of the LDEF, was not exposed to the ram effects of the atomic
oxygen. Even with the poor lighting on the experiment, it seems that few, if
any, of the forty (40) capture cell metallized Mylar covers survived the total
mission. At many cell locations, pieces of the failed capture cell cover have
curled into tight conical shaped needles and are seen attached to the edges
of the aluminum mounting frame. Non-magnetic stainless steel fasteners,
attaching the aluminum frame to the support structure, appear to be intact.

calorimeters are shown mounted on  sulfuric anodized aluminum mounting plates,
one plate uses the space of a capture cell in the top center of the experiment
panel and the second uses a similar space in the lower center of the panel. The
two (2) capture cell spaces in the upper right section of the panel are used
for electrical connection terminals which are protected by an aluminum cover.
Reflections of both personnel and equipment can be seen in the metallic coated

The experiment capture cells have been degraded by thier exposure to the space
environment. The experiment was located on the trailing edge of the LDEF and
was not exposed to the ram effects of the atomic oxygen; even so, only eleven
(11) of the seventy-seven (77) capture cell metallized Mylar covers survived.

Fragments of the failed capture cell covers, curled into tight conical shapes,
are attached to edges of the aluminum mounting frame. The brown colored stain
on the tray flanges, the capture cell mounting structure and on the calorimeter
mounting plates is a product of material outgassing / contamination. The darker
stain is thought to be in areas where adhesive material, used in mounting the
calorimeter, was not properly cleaned from the surface.

This postflight photograph shows an experiment that has been severely degraded
due to orbital exposure on the leading edge of the LDEF. The metallic coated
thin Mylar film has been lost on each of the capture cells. As the thin Mylar
film failed, the material curled tightly into small conical shapes and can be
seen still attached to the aluminum mounting structure edges of many capture
cells. Close examination of capture cells near the tray center clearly show the
four individual high purity germanium plates with some of the bonding material
exposed between plates. The green tint on the germanium plate at the right edge
of the experiment tray is a reflection from the lights in the high bay area of
SAEF II at KFC. Dim reflections from various sources can be seen on other
sections of the experiment.

The postflight photograph of the integrated tray (D02) was taken in the
Operations and Checkout (O&C) building after the LDEF was transferred from
the KSC Payload Canister to the LDEF Assembly and Transport System (LATS).

This photograph of the QuartzCrystal Oscillator experiment, upper left corner,
shows the effects of the space environment. The white paint has turned brown
due to interaction of the LDEF generated outgassing and contamination
products with the space environment. The stainless steel fasteners, the
resonator shields, the resonator holddown cages and the aluminum mounting plate
appear to have a similar brown tint.

The flight photograph was taken after the LDEF was retrieved and prior to
berthing in the Orbiter cargo bay.

The on-orbit photograph of the experiment, upper right corner, shows the paint
stripes that were orginally white are now a brown or tan color. The brownish
tint can also be seen on the fasteners, the resonator shields and the resonator
holddown cages. These coloration changes are thought to be a caused by
interaction of the LDEF generated outgassing and contamination products with
the space environment. The scratches and abraisions on the aluminum mounting
plate, that occurred during the fabrication and cleaning process, are more
visible than in either the pre-flight or postflight D02 integrated tray
photographs. The difference observed is probably due to the variation of
exposure and intensity of the light source.

Photo, Description==
The postflight photograph shows little change of the exposed surfaces when
compared with the prelaunch photograph. Although not noticable in the
photograph, a light coating of contamination was seen on all experiment
surfaces in this location. The difference in colors of the IDE detectors,
located on the right hand mounting plate, is a result of the reflected
surroundings and not related to space exposure.  A close observation of the
detector surfaces reveal that some damage has occured from meteroid and/or
debris impacts. One impact crater can be seen, upper right quadrant, on the
detector located in the sixth (6th) row down from the top and the fifth (5th)
row from the right. Other impacts, smaller in size, show as small white dots on
the detector surface.

The solar sensor seems to have changed little, if any.  However, the color of
the solar array baseplate, showing indications of contamination, appears to
be darker than the detector mounting plate.  The center section cover plate
shows little change when compared with the pre-launch photograph. However,
during inspection, a light coat of the brown contamination has been observed on
all surfaces. The color of the bonding material (RTV) used to secure several
thin specimen, sapphire, to individual mounting plates has changed from pink to
gold. At one location, that of a single specimen, the bonding material is more
gray than gold in color. This has been attributed to the specimen being
considerably thicker.

The EPDS thermal cover in the right hand side of the tray shows a light coating
of brown contamination on the Chemglaze II A-276 white paint.

Photo, Description==
The prelaunch photograph shows the six (6) inch deep Interplanetary Dust
Experiment (IDE) master control tray. The tray has three (3) mounting/cover
plates elevated on fiberglass stand-offs to provide clearance and protection
for hardware and electronics located underneath. The stand-offs also raise the
plates to a level that minimizes shading of detectors by the tray sidewalls.

The mounting plate located at the left hand end of the tray is populated with
eighty (80) metaloxide-silicon (MOS) capacitor-type impact sensors and one
(1) solar sensor that is located approximately in the center of the mounting
plate. The IDE sensors are two (2) inch diameter MOS capacitor structures
approximately 250 um thick. The detectors are formed by growing either 0.4um or
1.0um thick silicon oxide, SiO2, layer on the 250um thick, B-doped polished
silicon wafer. The top metal contact, the visible surface, was formed by
vapor deposition of 1000A of aluminum on the SiO2 surface. Aluminum was also
vapor deposited on the backside to form the contact with the silicon substrate.
Gold wires are bonded to the front and back aluminum layers for use in
connecting the detectors to the circuits. The complete wafers, IDE detectors,
are mounted on chromic anodized aluminum frames by bonding the detector
backside to the aluminum frame with a space qualified RTV silicon adhesive,
de-volatized RTV-511. The difference in colors of the detectors is caused by
reflections in the metallized surfaces. A reflection of one of the technicians
is visible in the three (3) rows of detector on the left hand side of the
mounting plate.

The solar sensor, located at the mounting plate center, consist of four (4)
silicon solar cells connected in series and associated circuity bonded to an
aluminum baseplate. The solar sensor registered each orbital sunrise
independant of LDEF orientation at the time of sunrise. When IDE solar sensor
data from the six (6) orthogonal faces of the LDEF was correlated, the
Interplanetary Dust Experiment clock could be precisely calibrated.

The center 1/3rd tray cover is a chromic anodized aluminum plate that protects
the IDE data conditioning and control electronics mounted underneath. The
cover plate also serves as a mounting platform for ten (10) individual specimen
holders provided by one of the IDE investigators.The material specimen,
consisting of germanium, sapphire and zinc sulfide of different sizes, shapes
and colors, are bonded to the specimen holders with an RTV adhesive. The
specimen holders are attached to the cover plate with stainless steel
non-magnetic fasteners.

The 1/3rd tray cover plate in the right hand end of the experiment tray is an
aluminum plate painted white with Chemglaze II A-276 paint and used as a
thermal cover for the Experiment Power and Data System (EPDS). The EPDS is a
system provided by the LDEF Project Office that processes and stores, on
magnetic tape, the orbital experiment and housekeeping data from six (6)
experiment locations on the LDEF.

The flight photograph was taken during the LDEF retrieval and provides an
on-orbit view of the C03 integrated tray. When comparing this photograph with
the prelaunch photograph, one of  the most noticeable changes is the brown
stain, attributed to outgassing and contamination, on the tray structure and
most aluminum surfaces of experiments within the tray.

The Interplanetary Dust Experiment hardware, that is visible and not in shadow,
appears to to have a thin brown film or stain on the exposed surfaces. A deeper
brown stain, probably from the material under the small electrical cover plate
on the detector frame, can be seen in  the upper left corner of some of the
detectors. The colors seen in the detectors mirror like surface is a reflection
of the sky and clouds.

The flight photograph was taken during the LDEF retrieval and provides an
on-orbit view of the C09 integrated tray. When comparing this photograph with
the prelaunch photograph, very little difference can be seen. A brown stain is
visible around some of the fasteners and on mounting plates. The stain has been
attributed to outgassing and contamination from the LDEF and experiment related
materials being flown. When compared to the prelaunch photograph, the C09
integrated tray seems to be in excellent condition.

The Interplanetary Dust Experiment appears to have a thin brown stain around
some of the fasteners and also a small rectangular stain, in the center,
along the bottom edge of the detector mounting plate. The IDE seems to be in
excellent condition with all hardware intact. The colors seen in the detectors
is a reflection of the Orbiter's white cargo bay liner.

The postflight photograph was taken prior to the experiment tray being removed
from the LDEF. The tray corner clamp blocks are un-anodized aluminum and that
alone accounts for the major difference in color between the corner clamp
blocks and the center clamp blocks.

The IDE mounting plate and the detector frames and detectors seem to be in
excellent condition.  Close inspection of the photograph reveals several
locations where impacts on detector surfaces are visible. A faint gold or tan
stain can be seen around several of the fasteners and in a rectangular
configuration, near the center, along the bottom edge of the detector mounting
plate.  Stains can also be seen near the top right edge of the solar sensor, on
the mounting plate, and around the extreme edges of the solar sensor baseplate.
The colors and designs seen on the detectors are reflections of the surrounding
area.

The postflight photograph, taken prior to removal of tthe experiment trays from
the LDEF, again shows a significant difference in the color of the paint dots
on the experiment tray clamp blocks. The direction and intensity of the
artifical light source has caused hot spots and reflections that tend to
wash-out the brown stain on the aluminum structure.

The IDE experiment appears to be in excellent condition in the postflight
photograph. All bond joints seem to have survived the space environment and the
experiment hardware seems to be intact. A close inspection of individual
detectors reveals locations where impacts have occurred and damage is present.
The artifical light intensity and direction are such that the actual color
variation across the experiment, top to bottom, is not visible. The darker
stain around the edges of the solar cells is still visible but not as distinct
as in the flight photograph. The blue color in the detectors metallic surface
is caused by reflections of the surrounding area. The white stripe running
diagonally across the top two (2) rows of detectors is the reflecton of a
safety control rope placed around the LDEF transporter to restrict access to
the LDEF spacecraft.

Photo, Description==
The flight / on-orbit photograph of the D06 integrated tray was taken from
the Orbiter aft flight deck during the LDEF retrieval, while the spacecraft
was attached to the remote manipulator system. During the mission, the tray
surface was at an angle of approximately eighty-two (82) degrees to the orbital
velocity vector and therefore exposed to a higher atomic oxygen flux than if it
had been parallel with the velocity vector. Note the difference in color of the
paint dots on tray clampblocks; white dots along the top edge, a light tan
color on the center dot and a dark brown stain on the dots along the bottom of
the photograph.  The dots near the top of the photograph are adjacent to
experiment location D07 and are exposed to a higher atomic oxygen flux than
those adjacent to experiment location D05. Impacts of  atomic oxygen with a
surface tends to scrub away contamination from the that surface and leave it a
much cleaner.

The IDE experiment, located in the left side of the tray, seems to be coated
with a thin coat of the brown contamination stain. The stain varies in color
from a light tan at the top of the experiment to a darker color at the lower
edge of the experiment baseplate. Darker smudges of the stain can be seen on
the solar sensor baseplate where the solar cells have been bonded in place. The
changes in colors seen in the detector surfaces, when compared to the prelaunch
photograph, is due to the surroundings that are being reflected. The
reflections seen in the flight photograph are from the sky in the lower rows of
detectors and the orbiter's cargo bay liner in the upper rows of detectors.
Close inspection of the detector surfaces reveals locations where partical
impacts have occurred.

Photo, Description==
The flight/on-orbit photograph of the G10 experi ment tray was taken from the
Orbiter aft flight deck during the LDEF retrieval.

A light brown stain can be seen on the experiment tray flanges and to a lesser
degree on the IDE Chemglaze Z tained their integrity. A light tan stain on the
solar sensor base plate, located in the center of the tray, is more easily seen
than that on the IDE mounting plate. Surface defects are highly visible due to
the lighting conditions existing at the time the photograph was taken. The
lighting angle is such that many impact craters can be seen. Two (2) detectors,
located in the twenty (20) detector layout in the lower left corner of the
tray,  seem to have defects. A triangular shaped discoloration appears on the
second detector from the left and in the second row from the bottom.  Another
irregular shaped discoloration can be seen on the fourth detector from the left
and in the third row from the bottom. These discolorations appear to be due to
material and/or fabrication defects and not reflected light. The blue colors on
the detector's mirror like surface are caused by reflections of the LDEF
surroundings.

The prelaunch photograph shows the Inter planetary Dust Experiment (IDE) in a
three (3) inch deep corner tray. The IDE is an active exper iment and is
located on the earth facing end of the LDEF in the G10 location.

AO201 - The Interplanetary Dust Experiment (IDE) is an active experiment
consisting of impact detectors, detector frames, a solar sensor and the
necessary mounting hardware. The eighty (80) detectors, metal-oxide-silicon
(MOS) capacitor-type impact sensors, bonded into anodized alumi num frames, are
attached to the aluminum mounting plate with non-magnetic stainless steel fas
teners. A solar sensor, four (4) silicon solar cells in series mounted on an
aluminum baseplate, is shown in the approximate center of the IDE mounting
plate. The different colors seen on the detectors are the reflections of  LDEF
technicians and the surrounding clean room work area.

Photo, Description==
The flight photograph was taken during the LDEF retrieval and provides an
on-orbit view of the H11 integrated tray. When comparing this photograph with
the prelaunch photograph, the most noticeable change is the brown stain,
attributed to outgassing and contamination, on the tray structure and most
aluminum surfaces of experiments within the tray. The white paint dots on the
experiment tray clamp blocks now appear to be brown.

The Interplanetary Dust Experiment hardware appears to have a thin brown film
or stain on the exposed surfaces. A deeper brown stain, probably from the
material underneath the small electrical cover plate of the detector frame,
can be seen in  the upper right corner of some of the detectors. Stain that
is seen on the solar sensor base plate varies from a medium brown color in some
areas to a faint tan near the top of the plate.  The colors seen in the
detector's mirror-like surface is a reflection of the sky and clouds. The dark
spot on the detector in the third row from the top seems to be a flaw in the
photograph since no damage was found in a postflight inspection.

joints. The detector bond joints and foil materials appear to be in-tact and
have maintained their integrity in all four (4) stacks. A light brown stain
and  a dark smudge mark near the center are visible on the thermal isolator
plate.

The Passive Grapple Tray flight photograph was taken while the LDEF was
attached to the Orbiter's RMS arm prior to berthing in the Orbiter's cargo bay.
The tray assembly consists of a modified six (6) inch deep LDEF peripheral
experiment tray, a chromic anodized aluminum mounting plate with chamfered
corners, an initiate switch assembly, an initiate system status indicator
assembly, non-magnetic stainless steel fasteners and a Modified Mechanical
Grapple Fixture, provided by JSC, with a camera target attached.  The camera
target, black with white markings, is attached to the right edge of the grapple
fixture to assist the operator in positioning the RMS end effector during
retrieval operations. The opening in the upper left corner of the mounting
plate provides access to the initiate system activation connectors and is
covered by an aluminum plate prior to installing the LDEF in the Orbiter cargo
bay.  The black square in the right center of the mounting plate, adjacent to
the camera target, is the initiate system status indicator assembly.

 The grapple tray assembly appears to be intact with no apparent  physical
damage. The white paint dots on the clamp block located at the center of the
trays left flange and at each end of the trays right flange have changed  to a
dark gray. The tray flanges appear to be discolored by a light brown stain.

The chromic anodized aluminum grapple fixture mounting plate appear to be
discolored by a light tan stain. The, as received aluminum, cover plate located
in the trays lower left corner has a number of irregular shaped stains around
the outer edges that appear to be finger prints. No change to the white paint
on the grapple fixture camera target  is apparent. The scratch marks on the
upper right corner of the mounting plate were observed in the prelaunch
photograph. The arc shaped discoloration in the upper left section of the
tray does not appear on the postflight photos. The dark gray circular
discolorations on the outer section of the grapple fixture appear to be the
locations of impact craters where the surrounding surface coating has been
disturbed.

tray flanges have become discolored by a light brown stain.

The chromic anodized aluminum mounting plate and the passive grapple fixture
appear to be discolored by a light brown stain similar to that on the tray
sidewall and flanges. The dark irregular shaped discoloration on the lower
right corner of the grapple fixture mounting plate is an abrasion that existed
preflight. The pinkish tint on the mounting plate is the by-product of the
chromic anodizing process and is not attributed to exposure to the space
environment. The white stripes on the black camera target and the white tip of
the vertical rod located on the target have changed in color from white to
brown. The light band along the right edge of the grapple fixture mounting
plate is caused by light reflecting from the tray sidewalls.

The LDEF structure is shown, from a rear oblique angle, mounted on the LDEF
Assembly and Transport System (LATS)in the SAEF II at the KSC after
deintegration of experiments from the LDEF. The LDEF structure is a welded /
bolted assembly fabricated from aluminum alloy 6061-T6 extrusions, forgings,
tubing and plate materials and assembled with stainless steel fasteners. The
eight (8) internal tubular diagonals between the center ring structure and the
two end frames provides torsional stiffness to the structure. The passive
grapple tray remains mounted in the LDEF C01 location. A thermal control panel,
adjacent to the LDEF experiment F06 location, was removed prior to experiment
deintegration in preparation for configuring the LDEF for rotation. A light
brown discoloration can be seen on the anodized aluminum thermal control panels
on the LDEF Space end. Discolorations are also visible on surfaces of the
LDEF longeron and intercostal structures that were exposed during the
mission.

The postflight photograph was taken prior to the experiment being removed from
the LDEF structure. The experiment's damaged multi-layer ther mal insulation
blankets were removed from the experiment to accommodate experiment tray cover
installation prior to operations that removed the experiment from the LDEF.

The postflight photograph of the Heavy Ions in Space Experiment shows the four
(4) experiment modules with the multi-layer thermal blankets severely degraded.
The paint on the the thermal blankets top layer, previously white, is now a
glossy tan or soft brown color. This change in color, from white to tan, was
seen on other LDEF experiment surfaces that were coated with the same paint.

The tape used to attach the thermal blanket to the module frames, 3M Y966 with
a silvered Teflon film backing, failed during flight. The tape failed in
tension across the width of the tape leaving portions of the tape on both the
frame and the top layer of the thermal blanket. The tape failure is attributed
to shrinkage of the thermal blanket which caused a significant buildup in
tension across the taped joint. Detachment of the blankets along two (2) sides
relieved the tension buildup and the blanket remained in place, although
curled, during retrieval and post retrieval operations. The material exposed
underneath the curled thermal blanket is the top sheet of the Lexan detector
stack.

The degraded multi-layer thermal blankets in each of the four modules show
details of the blanket construction. The top layer of the thermal blanket is a
5 mil Kapton film with an aluminum coat ing vapor deposited on one side and
with an exterior overcoat of Chemglaze II A-276 white paint on the other. The
core or center section of the thermal blanket is constructed of approximately
twenty two (22) layers of 1/4 mil perforated Mylar film with an aluminum
coating vapor depos ited on each side. The bottom layer of the thermal blanket
is also a 5 mil Kapton film with an alu minum coating vapor deposited on one
side.

The aluminum coated side of the Kapton film faces the adjacent Lexan detector
stack sheet. A Dacron mesh (bridal veil) separator, clearly visible in the
upper right module, is placed between each aluminized Mylar layer of the core
material and also between the core material and the alu minized Kapton film
used for the top and bottom covers. Insertion of the Dacron mesh between the
aluminized layers minimizes heat leaks within the thermal blanket.

A close observation of the exposed edges of the Multi-layer blankets shows the
vapor deposited aluminum coating has delaminated from from the Mylar film and
the Mylar film has eroded. The delaminated aluminum can be seen extending from
the blanket material in the lower right module.  Small pieces of aluminum have
been observed adhered to surfaces of the LDEF, to the surfaces of some LDEF
experiments and in the orbiter cargo bay during post-flight inspections. Also
note the loss of portions of the Dacron mesh material. The loss of the Dacron
material and some of the alu minum delamination is thought to have occurred
prior to retrieval, however, a significant portion of the aluminum delamination
from the Mylar is thought to have occurred post-landing due to the velocity and
direction of air from the cargo bay purge system.

The flight photograph of the Heavy Ions in Space Experiment was taken from the
Orbiter's aft flight deck during LDEF retrieval operations. A light tan stain
can be seen on the LDEF end structure along the left edge of the experiment
tray flange.  Lighter stains are also visible on the tray flange between the
top and the center tray clamp blocks on that side.

The photograph shows four (4) experiment modules mounted in the LDEF provided
end center experiment tray. An experiment module consist of the thermal cover,
a top stack of Lexan sheets for detecting low-energy ions,  a honeycomb
pressure cover and the main stack of CR-39 used to detect cosmic rays mounted
in an aluminum housing. The four modules are identical in materials and
construction. The exposed surface of each module is a white paint overcoat,
Chemglaze II A 276, that has been applied to the top layer, aluminized Kapton,
of a multi-layer thermal blanket.  The frame around each of the four modules, a
Z shaped aluminum structure, is covered with a sil verized Teflon film secured
with 3M Y966 acrylic transfer tape. The 3M Y966 transfer tape on a siliverized
Teflon film is also used to attach the four edges of the multi-layer thermal
blankets to the modules frame. The combination of the silverized Teflon and the
white paint provides the appropriate optical properities needed to meet
experiment thermal requirements.

The multi-layer thermal insulation blanket has extensive damage. The tape
joints have failed along two (2) sides of each experiment module and have
allowed the multi-layer insulation blan ket to curled back over its self. The
golden colored surfaces that have been exposed are the top sheet of the
experiment's Lexan detector stacks that are held securely in place by the Z
shaped alu minum structure.

flange. Lighter stains that appear to be finger prints are also visible on the
trays top flange. The paint on the top layer of the thermal blankets, origi
nally white, now appears brown or light tan. The fragments of aluminum in the
lower two quad rants appear to be the results of delamination of the vapor
deposited aluminum from the thin aluminized Mylar thermal film.

The postflight photograph of the Heavy Ions in Space Experiment was taken prior
to the experiment being removed from the LDEF structure.  The experiment's
damaged multi-layer thermal insulation blankets were removed from the exper-
iment, so the experiment tray cover could be installed, prior to removing the
experiment from the LDEF

The Postflight photograph shows the four (4) experiment modules with multilayer
thermal blankets that are severely degraded. Paint on the top layer,
previously white, is now a glossy soft brown or tan color. The thermal blankets
apparently shrunk in flight causing them to detach from the modules frame along
two sides, thereby relieving the tension buildup. The tape used to attach the
blanket to the structure failed in tension across the width of the tape leaving
portions of the tape on both the frame and the top layer of the thermal
blanket.

The thermal blankets on the three (3) large modules have curled to expose the
top Lexan layer of the detector stack beneath. The curled thermal blankets that
protected the four (4) smaller modules now exposes the 5 mil aluminized
Kapton pressure covers beneath.

The damaged thermal blankets shown in the two (2) tray quadrants on the right
side of the photograph reveal representative cross sections of the multilayer
thermal blankets. The thermal blankets top layer is a 5 mil aluminized Kapton
film with an exterior overcoat of Chemglaze II  A-276 white paint.

The blanket core, center section of the blanket, is constructed of
approximately twenty two (22) layers of 1/4 mil perforated Mylar film with
aluminum vapor deposited on each side. A Dacron mesh separator, clearly seen in
the lower right quadrant, is placed between each aluminized Mylar layer of the
core material and also between the core material and the aluminized Kapton film
used for  the thermal blanket top and bottom covers. Insertion of the Dacron
mesh between the aluminized layers minimizes heat leaks within the thermal
blanket.

The post landing photograph of the Heavy Ions in Space Experiment was taken
from the Orbiter's cargo bay access hatch during post landing operations to
prepare the Orbiter for the ferry flight from the Dryden Flight Research Center
to the Kennedy Space Center.

The photograph shows the extensive damage to the experiment's multi-layer
thermal blankets that occurred during the LDEF mission. It appears that
siliverized Teflon tape backed with an acrylic transfer tape that was used to
attach the thermal blankets to the structure failed in tension. When the bond
joint released along two (2) sides, the tension was relieved and the remaining
tape continued to hold the blanket to the structure through out the rest
mission. The outside blanket surfaces that were originally painted white are
now coated with a glossy dark brown stain. The golden colored material in the
three (3) full modules are the top sheets of lexan detector stacks held in
place by the aluminum Z shaped structure. The deep rich redish-brown colored
sections visible in one half (1/2) of the upper left module is also the top
layer of detector sheets underneath support straps. In the two lower quadrants,
the aluminum coatings that were vapor deposited on thin Mylar sheets of thermal
blanket material appear to be starting to delaminate from the Mylar.  A light
coating of brown stain can be seen on the trays right flange. The stain appears
heavier in the vicinity of nutplates used to attach the protective tray
cover.Smudge marks that appear to be fingerprints can be seen along the edge of
the thermal panel to the right of the experiment tray.

The flight photograph was taken from the Orbiter aft flight deck during the
LDEF retrieval prior to berthing the LDEF in the Orbiter cargo bay. The Trapped
Proton Energy Spectrum Determination Experiment consist of three (3) experi-
ment modules located in three (3) inch deep LDEF integrated trays. Additional
Trapped Proton Energy Experiment modules are located in a peripheral LDEF
integrated experiment tray in the D09 location and in an end center integrated
tray in the G12 tray location.

The Trapped Proton Energy experiment, located in the lower right corner of the
integrated tray, consist of a primary experiment and two (2) secondary
experiments mounted on an aluminum mounting plate. The primary experiment
components include six (6) stacks of CR-39 passive detectors in individual
aluminum housings and an aluminum support structure, configured to provide
the desired exposure for the detector stacks. The secondary experiments are the
Neutron and Proton Activation experiment that exposes metal samples to the
ambient flux throughout the mission, and the Flux Measurement by Ion Trapping
experiment consisting of a variety of sample materials that are exposed to the
space environment for the total mission. The exterior surfaces of the aluminum
honeycomb mounting plate, the experiment housings and the support structure are
coated with IITRI S13G-LO white paint. The identification plate in the left
center of the experiment module  identifies the experiment location and
orientation in the experiment tray. The experiment is assembled using
non-magnetic stainless steel fasteners and safety wire.

The Trapped Proton Energy experiment appears to be intact with with no apparent
damage. A light tan discoloration is visible on the Trapped Proton Energy
experiment detector housings and on the surfaces of the experiment support
structure. The discoloration around the outer edges of the experiments
honeycomb mounting plate and around vent holes in the honeycomb appears to be a
darker tan color. The sub-experiments are intact and secure with no visible
damage, however, colors have changed from light  gray to black.

inch tray and one three inch tray with a connecting wiring harness, one EPDS,
one EECC and six LiSO2 batteries were located in tray locations D08 and D09
near the LDEF leading edge and a similar set of hardware was located near the
LDEF trailing edge in tray locations D03 and D04. The environmental exposure
was similar with one significant exception, the trailing edge location was not
exposed to continuous bombardment by the relativity high atomic oxygen flux.

The experiment tray in the D04 location is divided into three sections.The
right section provides space for the EPDS, the center section accommodates the
Signal Conditioning Unit (SCU) and an experiment mounting plate, on an aluminum
sub-structure, that is populated with composite material samples. The left
section houses the EECC with a complement of experiment samples that consist of
coatings, thermal paints, polymers, glasses, semi-conductors. Detectors within
the experiment provide environmental data for use in postflight analyses.
Batteries and inter-tray wiring harness are located beneath the tray base
plates. The EPDS is underneath an aluminum cover, coated with a white thermal
control paint (Chemglaze II A-276) and thermally isolated from the tray
structure by fiberglas clips. The SCU cover is also coated with a white thermal
control paint, IITRI S13G-LO, and the EECC is covered with a chromic anodized
aluminum thermal cover.

The white paint (Chemglaze II A-276) on the EPDS cover has turned to a medium
brown and the IITRI S13G-LO white paint has become light tan or off-white in
color. Colors of the composite material samples are clear but not as bright as
in the flight photograph. The material samples that appeared blue in the flight
photograph are more subdued with very little of the blue tint observed.

The composite materials experiment mounting plate has discolorations varying
from a light tan to a medium brown and the rectangular aluminum cover plate
located in the upper left corner of the experiment is a uniform light brown
color.

The thermal covers on the EECC that appeared to be a lavender or purple color
in the flight photograph is the color of anodized aluminum in the postflight
photos. The dark square shaped discolorations on the upper corners of the
thermal cover are pads of tape used to cover sharp corners that were exposed.
The pads were not in place in the prelaunch photograph.

The flight photograph was taken from the Orbiter aft flight deck during the
LDEF retrieval prior to berthing the LDEF in the Orbiter cargo bay.  Experiment
Power and Data Systems (EPDS), two Environment Exposure Control Canisters
(EECC), twelve LiSO2 batteries and internal support structure, instrumentation
and black anodized aluminum mounting plates for experiment samples. The
experiment structural members were assembled using non-magnetic stainless steel
fasteners. One six-inch tray and one three-inch tray with a connecting wiring
harness, one EPDS, one EECC and six LiSO2 batteries were located in tray
locations D08 and D09 near the LDEF leading edge and a similar set of hardware
was located near the LDEF trailing edge in tray locations D03 and D04. The
environmental exposure was similar with one significant exception, the
trailing edge location was not exposed to continuous bombardment by the
relativity high atomic oxygen flux. The white paint dots on the experiment tray
clamp blocks appear to have no significant change in color.

The experiment tray in the D08 location is divided into three sections.The top
section provides space for the EPDS, the center section accommodates the Signal
Conditioning Unit (SCU) and an experiment mounting plate, on an aluminum
sub-structure, that is populated with composite material samples. The lower
section houses the EECC with a complement of experiment samples that consist of
coatings, thermal paints, polymers, glasses and semiconductors. Detectors
within the experiment provide environmental data for use in postflight
analyses. Batteries and the inter-tray wiring harness are located beneath the
tray base plates. The EPDS is located under an aluminum cover that is coated
with a white thermal control paint (Chemglaze II A-276) and thermally iso-
lated from the tray structure by fiberglass clips. The SCU cover is also coated
with a white thermal control paint, IITRI S13G-LO, and the EECC is protected
with a chromic anodized aluminum thermal cover.

The white paint (Chemglaze II A-276) on the EPDS cover has no apparent change
in color but the IITRI S13G-LO white paint on the SCU cover has a brownish tint
with a darker tan strip along the right vertical line of screws. Colors of the
composite material samples are bright and clear with some material samples
appearing to be blue in this photograph but not in prelaunch or postflight
photographs. A discoloration on the samples located in the lower right corner
of the mounting plate is apparent. The composite materials experiment mounting
plate has discolorations varying from a light tan to a medium brown along the
lower edge and the rectangular aluminum cover plate located in the lower left
corner of the experiment is a uniform brown color. The thermal covers on the
EECC are intact and appear to have a light brownish tint. The swirls and
streaks on the larger cover appear to be from the preflight cleaning process
and are enhanced by the lighting.  The dark square shaped discolorations on the
upper corners of the thermal cover are pads of tape used to cover sharp corners
that were exposed. The pads were not in place in the prelaunch photograph.
The canister base plate has become discolored by a brown stain during the
mission.

and a similar set of hardware was located near the LDEF trailing edge in tray
locations D03 and D04. The environmental exposure was similar with one
significant exception, the trailing edge location was not exposed to continuous
bombardment by the relativity high atomic oxygen flux. The originally white
paint dots on the clamp block located in the center of the trays right flange
and on the clamp blocks at each end of the left flange appear to be off-white.

The experiment tray in the D09, leading edge, location is divided into six
sections. One of the six sections, upper right corner, provides space for one
of three Trapped Proton Energy Spectrum Determination Experiment, M0002-01,
modules. The other five sections of the tray contain M0003 sub-experiments
consisting of coatings, thermal paints, polymers, glasses, composites, solar
power components, semi-conductors and detectors that provide various
environmental data.

The experiment, overall, appears in good condition. The experiments located in
the upper left and center left sections are heavily coated with debris
particles from other degraded experiments.  Experiments in three of the five
sections appear to have survived the mission intact with minor physical damage.
Experiments in the other two sections have sustained damage to thin metallized
and/or coated polymer samples. The material samples located in upper left
section of the tray consist of a composite plate with two quadrants painted
white, one quadrant painted black and one quadrant remaining bare. The
experiment remains intact with the only apparent change being the color of the
bare composite. The samples in the center left and the center right tray
sections remain intact but appear sharper and brighter due to the excess blue
in the photo. In the center left section, the plate securing the three
rectangular samples along the right edge appears to have changed from dark
brown to a light tan color. Along the left side the two horizontal rectangular
aluminum mounting brackets appear gold in color and the square sample mount in
the upper left corner has changed from dark brown to a light tan. Two thin film
solar cells are missing and the cell mountings appear to have changed colors.
The experiment in the center right section appears to be intact with only a
few  samples changing colors. The two white circular samples were bright yellow
and the two light tan square mounts to the right  of the four off-white squares
were dark brown in the prelaunch photograph. The experiment in the lower left
section of the tray consist of three metallized polymer and one coated polymer
samples.The test sample in the upper left corner, a grid of metallic foil
squares on a Kapton sheet, is essentially gone. The sample in the upper right,
a metallized Kapton sheet, appears to be intact with only a few spots where the
foil is missing. The sample in the lower left corner, a Kapton sheet
imprinted with a pattern of metallic foil tripoles, is severely degraded and
remains attached in only a few spots. The test sample in the lower right
corner, Kapton sheet with a white paint overcoat, appears to be intact only a
change in color from white to a light gray.  The other two samples, upper
right  and lower left corners,  are severely degraded.

The metallized and coated polymers located in the lower right tray section
appear to have survived the exposure intact but are discolored. Approximately
half of the thin film polymers in the upper right

corner of the section are loose at one end but remain attached. The silver
Teflon cover, the large rectangular shape near the center of the section,
appears to remain intact but has changed to a milky white color. Thermal
control coatings, mounted along the left side of the section, are discolored
as are the exposed surfaces of the sample holders.

The postflight photograph was taken in the SAEF II at KSC prior to removal of
the experiment from the LDEF. The color of the white paint dot on the center
clamp block of the experiment tray lower flange appears to be unchanged.

The Space Environment Effects on Fiber Optic Systems Experiment occupies a six
(6) inch deep LDEF peripheral tray and consist of an aluminum internal support
structure, an Electronic Power and Data System (EPDS), three aluminum
experiment mounting plates, two aluminum cover plates, four operational digital
optical data links (lengths of 48 m, 45 m and two 20 m) exposed to the space
environment, three passive cabled fiber optic links (each 10 m long) with
electronic components and end connectors, aluminum brackets and non-magnet
stainless steel fasteners required to assemble the experiment.

Four active cabled optical fiber links (one black, one blue, one yellow and one
light tan), each configured in  the form of a planar, helix coil, are attached
to thermally isolated mounting plates with black anodized aluminum clips
cushioned with silicone-rubber spacers. The three mounting plates are coated
with a Catalac off-white thermal control paint, the large cover plate is coated
with Chemglaze II A-276 white paint and the smaller cover plate is coated with
IITRI S13G-LO white paint to meet  thermal control requirements.  The three
passive cabled optical fiber links and all emitters, detectors and associated
electronics are located in the interior volume of the tray. All cabled optical
fibers terminate in connectors mounted in brackets that are located in the tray
bottom or on the backside of the thermally isolated mounting plates.

The Space Environment Effects on Fiber Optic Systems Experiment appears to be
intact with no apparent structural damage. Colors of all three exposed coils of
fiber optic cables have changed significantly. The cable located in the lower
right corner, originally glossy black, appears to be dark brown and the cable
in the lower left position, originally a glossy royal blue, now appears to be a
navy blue color. The two 20 m coils of fiber optics links appear to have more
extensive color changes. The originally yellow cable, that appeared slate gray
in the flight photograph, now appears a light gray and the brown cable in the
flight photograph appears to be a lighter brown.  Details of the discoloration
above the light gray coiled link, observed in the flight photograph, can be
seen. The color of the silicone-rubber spacers under the coil attach clips have
changed from clear to brown and appear to have discolored the light gray cable
link. Brown discolorations appear on the left edge of the large cover plate and
on the tray structure in the vertical clearance (top, center and bottom)
between the mounting plates The Chemglaze white paint on the large cover plate
appears to have maintained the prelaunch color but the IITRI S13G-LO white
paint on the small cover plate appears to have changed to a uniform light tan
color. Spots on the large cover plate that appeared to be impact craters in the
flight photograph can be seen on the white paint in the lower left corner of
the plate. Other craters, not readily visible in the flight photograph, can
also be seen.

Photo, Description==
The prelaunch photograph was taken in SAEF II at KSC prior to installation of
the Space Environment Effects on Fiber Optic Systems Experiment  on the LDEF.

The Space Environment Effects on Fiber Optic Systems Experiment occupies a six
(6) inch deep LDEF peripheral tray and consist of an aluminum internal support
structure, an Electronic Power and Data System (EPDS), three aluminum
experiment mounting plates, two aluminum cover plates, four operational digital
optical data links (lengths of 48 m, 45 m and two 20 m) exposed to the space
environment, three passive cabled fiber optic links (each 10 m long) with
electronic components and end connectors, aluminum brackets and non-magnet
stainless steel fasteners required to assemble the experiment.

Four active cabled optical fiber links (one black, one blue, one yellow and one
light tan), each configured in  the form of a planar, helix coil, are attached
to thermally isolated mounting plates with black anodized aluminum clips
cushioned with silicone-rubber spacers. The three mounting plates are coated
with a Catalac off-white thermal control paint, the large cover plate is coated
with Chemglaze II A-276 white paint and the smaller cover plate is coated with
IITRI S13G-LO white paint to meet thermal control requirements.  The three
passive cabled optical fiber links and all emitters, detectors and associated
electronics are located in the interior volume of the tray. All cabled optical
fibers  terminate in connectors mounted in brackets that are located in the
tray bottom or on the backside of the thermally isolated mounting plates.

Photo, Description==
The flight photograph was taken while the LDEF was attached to the Orbiter's
RMS arm, seen along the left side of the photograph, and provides an on-orbit
view of the C02 integrated tray. When comparing this photograph with the
prelaunch photograph, one of the most noticeable changes is the brown stain,
attributed to outgassing and contamination, on the experiment hardware within
the tray.

M0006  The EECC containing the M0006 experiment appears to be in excellent
shape after the sixty nine (69) month mission. A light brown stain is visible
on the base plate, the canister support rails and the canister's thermal
covers. Close inspection reveals impact craters, seen as white dots, in several
locations on the thermal covers and on the base plate.

Space Environment experiment is contained within the Experiment Exposure
Control Canister (EECC) that is located in the right one third (1/3rd) of the
experiment tray. The EECC hardware consists of the housing, the drawer that
contains the experiment samples, the drawer opening and closing mechanism (a
screw drive system) and chromic anodized aluminum thermal covers that are
seen in the photograph. The hardware is fabricated from aluminum or
non-magnetic steels and is assembled with non-magnetic stainless steel
fasteners. The canister will be opened in orbit after the LDEF has been
deployed, the Orbiter has departed and initial outgassing of materials on the
LDEF has occurred. The canister is programmed to close approximately nine (9)
months after opening and prior to the scheduled LDEF retrieval. Experiment
samples located in the EECC consist of mirrors, fiber optic components,
semiconductors, polymer films and seeds housed in a sealed aluminum tube.

direction of the orbital velocity vector and therefore exposed to the higher
flux levels of atomic oxygen.  The image shows the surfaces immediately after
the LDEF arrived in SAEF II and prior to initiation of deintegration
operations. Most experiments appear to be intact. however, the Solar Array
Materials Experiment (AO171) located in a tray in the upper left corner (tray
A08) appears to have several solar array assemblies missing and the Exposure of
Spacecraft Materials Experiment (S0010) located in the LDEF experiment B09
position appears to be missing most of the thin film polymer samples. The
silver Teflon thermal cover material appears opaque with randomly located dark
circular spots that appear to be debris points of impact. The painted surfaces
on both the experiments and the scuff plates appear to be essentially the same
as preflight.

The image provides an overall view of LDEF experiments located in Bays  A , the
bay adjacent to the center ring structure, thru Bay  C in Rows 06, the upper
row, thru Row 09, the lower row. The LDEF is  mounted on the LDEF Assembly and
Transport System (LATS) in the rotation mode. The surfaces of experiments
located on LDEF rows 09, 08, and 07 were facing in the direction of the orbital
velocity vector with row 09 experiments exposed to the highest flux level of
atomic oxygen and rows 08 and 07 receiving lesser flux. The image shows the
surfaces immediately after the LDEF arrived in SAEF II and prior to initiation
of deintegration operations. Most experiments appear to be intact. The silver
Teflon thermal cover material on experiments located in the A09 and C08
positions appears opaque while the same material in the B07 and C06 appears
specular.The yellow paint on the scuff plate and the white paint on experiment
surfaces appear in near prelaunch condition.

LDEF retrieval and prior to the berthing of LDEF in the Orbiter's cargo bay.

The Seeds in Space Experiment (P0004-01) is one of three passive experiments
located in a 6-inch deep LDEF peripheral tray. The experiment consist of 2
million seeds of 120 different varieties, one sealed canister, two smaller
vented canisters, and a silvered Teflon thermal cover. Two other experiments,
the Space Exposed Experiment  Developed for Students (SEEDS) P0004-02 and the
Linear Energy Transfer (LET) Experiment (P0006), were companion experiments in
the tray. The experiment hardware was assembled and mounted in the experiment
tray with non-magnetic stainless steel fasteners. The paint dots, originally
white, located on experiment tray clamp blocks now appear brown. The experiment
tray flanges also appear to be discolored.

The sealed Seeds in Space Experiment canister, a base portion and a dome
portion, was machined from aluminum and  assembled together with a butyl rubber
o-ring seal. The machined interior was approximately 4 inches deep with a 12
inch internal diameter, providing a volume of approximately 1/3 cubic foot.
The two vented canisters were also aluminum. One canister, 4 inches in diameter
and 4 inches high, was mounted on the top side of the experiment tray and  the
other was rectangular in shape and mounted on the bottom side of the tray, the
side facing the LDEF interior.  The exterior surfaces of all canisters located
on the top side of the experiment tray were painted white with Chemglaze II
A-276. The exterior surface of the rectangular canister on the bottom side of
the experiment tray was coated with Chemglaze Z-306 flat black paint over a
Chemglaze 9924 primer. Thermal control was accomplished by placing the
canisters on fiberglass isolators and covering the experiment tray with a thin
(5 mil) silvered Teflon specular cover secured with Velcro pads located on each
of the canister domes and on clips attached to the tray sidewalls.

The silvered Teflon thermal cover appears to be intact with no apparent damage.
The three dark spots appearing in a vertical row about a third of a tray width
from the right edge of the cover are the locations of three Velcro pads.

plate material and  assembled together with a butyl rubber o-ring seal. The
machined interior was approximately 4 inches deep with a 12 inch internal
diameter, providing an open volume of approximately 1/3 cubic foot  in each
canister. The 5 canisters were were mounted in the experiment tray along with a
similar canister containing the Seeds in Space Experiment. The exterior
surfaces of all canisters were painted white with Chemglaze II A-276 and
surfaces facing the LDEF interior were coated with Chemglaze Z-306 flat black
paint over a Chemglaze 9924 primer. Thermal control was accomplished by placing
the canisters on fiberglass isolators and covering the experiment tray with a
thin (5 mil) silvered Teflon specular cover secured with Velcro pads located on
each of the canister domes and on clips attached to the tray sidewalls. The
silvered Teflon thermal cover appears to be intact with no apparent damage. The
surroundings reflected in the thermal covers specular surface provide an array
of colors including white, browns, silver, red, and aqua.

The postflight photograph was taken in the SAEF II at KSC after the experiment
was removed from the LDEF and the silvered Teflon thermal cover was removed
from the experiment tray.

The Space Exposed Experiment  Developed for Students (SEEDS) P0004-02 is one of
three passive experiments located in a 6 inch deep LDEF peripheral tray. The
experiment consist of 12 1/2 million Rutgers tomato seeds, five sealed
canisters and a silvered Teflon thermal cover. Two other experiments, the Seeds
in Space Experiment (P0004-01) and the Linear Energy Transfer (LET) Experiment
(P0006), were companion experiments in the tray. The experiment hardware was
assembled and mounted in the experiment tray with non-magnetic stainless steel
fasteners.  Areas of the experiment tray flanges covered by the tray clamp
blocks are unstained and clearly visible.

The sealed SEEDS canisters, 5 bases and 5 domes, were machined from aluminum
plate material and  assembled together with a butyl rubber o-ring seal. The
machined interior was approximately 4 inches deep with a 12 inch internal
diameter, providing an open volume of approximately 1/3 cubic foot  in each
canister. The 5 canisters were mounted in horizontal rows in the experiment
tray along with a similar canister, located in the center of the top row,
containing the Seeds in Space Experiment. The exterior surfaces of all
canisters were painted white with Chemglaze II A-276 and surfaces facing the
LDEF interior were coated with Chemglaze Z-306 flat black paint over a
Chemglaze 9924 primer. Thermal control was accomplished by placing the
canisters on fiberglass isolators and covering the experiment tray with a thin
(5 mil) silvered Teflon specular cover secured with Velcro pads seen on each of
the canister domes and on clips attached to the tray sidewalls. The experiment
hardware appears intact and in prelaunch condition. The Chemglaze II A-276
white paint has no apparent discolorations.

photograph of each Debris Experiment tray was not taken prior to installation
of the tray on the LDEF.

The Space Debris experiment consist of two (2) three sixteenth (3/16th) inch
thick chromic anodized aluminum panels mounted in a three (3) inch deep
peripheral LDEF experiment tray. The side of the panels exposed to the LDEF
interior are painted black with Chemglaze Z-306 flat black paint over a
Chemglaze 9924 wash primer. The panels are attached to the aluminum tray
structure with non-magnetic stainless steel fasteners. The panel coatings, a
thin layer of chromic anodize facing out and the Chemglaze Z-306 black paint
facing the LDEF interior, contribute significantly to thermal control of the
LDEF spacecraft.

Photo, Description==
The postflight photograph was taken in the SAEF II at KSC prior to experiment
removal from the LDEF. The originally white paint dots on clamp blocks at the
center of the upper tray flange and at the center of the right flange are now
brown. Since this tray is located adjacent to the LDEF's trailing edge, very
little, if any, contami- nation has been cleaned away by atomic oxygen
impacts.

The greenish-gray and pink tints on the two (2) debris panels are a by-product
of the chromic anodize coating process and not attributed to contamination
and/or exposure to the space environment. The finger prints along the edges of
the left panel that were observed in the flight photograph are still visible.
Those seen previously along the top edges have been washed out by the lighting.
The light band along the sides and across the bottom of the panels is caused by
light reflecting from the tray sidewalls.

The flight photograph was taken while the LDEF was attached to the Orbiter's
RMS arm prior to berthing in the Orbiter's cargo bay. A combination of the
space environment and contamination has caused the paint dot on the clamp block
located at the center of the bottom tray flange to change from their original
white color to dark brown.  Finger prints observed on the lower tray flange and
sidewall indicate the lack of proper preflight handling/cleaning.

The Space Debris Impact Experiment consists of a three sixteenth (3/16) of an
inch thick chromic anodized aluminum panel mounted in a three (3) inch deep
LDEF experiment tray. The side of the plate exposed to the LDEF interior is
painted with Chemglaze Z-306 flat black paint over a Chemglaze 9924 wash

The flight photograph was taken while the LDEF was attached to the Orbiter's

and are not attributed to exposure to the space environment. The blue color
component that makes the discolorations on the panels appear more vivid is a
reflection of deep space and not a true change in surface color. The brown
irregular shaped discolorations along the center edges of the debris panels
appear to be fingerprints from prelaunch handling. The black unit  located on
the top panel is a keel camera target used during the berthing of the LDEF. The
color of the stripes and the tip of the vertical rod appear darker than in the
prelaunch photograph. The light band across the top panel is reflected light
from the tray sidewall and the dark band down the right side of the panels is a

A portion of the greenish-gray tint on the two (2) debris panels are
by-products of the chromic anodize coating process, however, additional blue
can be attributed to reflections of the blue sky.  The vertical streaks on the
debris panels are by-products of chromic anodizing that have been enhanced by
the blue reflection. Brown stains are located along the left edge of the right
debris panel. An irregular shaped discoloration extends horizontally across the
lower half of the left debris panel. The light band along the vertical edge of
the left debris panel and across the top of both debris panels is a reflection
from the tray sidewall.

Photo, Description==
The postflight photograph was taken in the SAEF II at KSC prior to experiment
removal from the LDEF. The originally white paint dot on clampblocks around the
perifery of the experiment tray show the results of contamination and exposure
to the space environment.  The variation in color, from off-white along the top
flange to different shades of brown at other locations, is attributed to
variations in the atomic oxygen flux intensity. Surfaces exposed to a higher
atomic oxygen flux will have less contamination due to the scrubbing or
cleaning action of the atomic oxygen molecule impacting that surface.

The pink and the greenish-gray tints on the two (2) debris panels are
by-product of the chromic anodize coating process and not attributed to
contamination and/or exposure to the space environment. The light bands along
the bottom and the left and right edges of the panels are caused by lights
reflecting from the tray sidewalls. The two (2) small mounds seen on the panel
on the left are manufacturing defects that existed prior to flight.

The flight photograph was taken while the LDEF was attached to the Orbiter's
RMS arm prior to berthing in the Orbiter's cargo bay. The color of the paint
dot on the clamp block located at the top center of the upper tray flange seems
unchanged from its orginal white color. Contamination has caused the white
paint dots on other tray clamp blocks to turn a light tan color.

The Space Debris Impact Experiment consists of a three sixteenth (3/16) of an
inch thick chromic anodized aluminum panel mounted in a three (3) inch deep
LDEF experiment tray. The side of the plate exposed to the LDEF interior is
painted with Chemglaze Z-306 flat black paint over a Chemglaze 9924 wash
primer. The panels are attached to the aluminum tray structure with non-
magnetic stainless steel fasteners. The panel coatings, a thin layer of chromic
anodize facing out and the Chemglaze Z-306 black paint facing the LDEF
interior, contribute significantly to thermal control of the LDEF spacecraft.

of the chromic anodize coating process, however, a large part can be
attributed to reflections of the blue sky. The vertical streaks on the panels
are products of chromic anodizing that have been enhanced significantly by the

atomic oxygen impacts.

The greenish-gray and pink tints on the two (2) debris panels are a by-product
of the chromic anodize coating process and not attributed to contamination
and/or exposure to the space environment. The smudges on the panels along the
top center of the tray are the results of improper cleaning after panel

The Space Debris Impact Experiment consists of a three sixteenth (3/16) of an

LDEF experiment tray. The side of the plate exposed to the LDEF interior is
painted with Chemglaze Z-306 flat black paint over a Chemglaze 9924 wash

magnetic stainless steel fasteners. The panel coatings, a thin layer of chromic
anodize facing out and the Chemglaze Z-306 black paint facing the LDEF
interior, contribute significantly to thermal control of the LDEF spacecraft.

The greenish-gray tint on the debris panels is a by-product of the chromic
anodize coating process. The dark green smudge along the top right edge of
the left debris panel is the results of improper cleaning after prelaunch
handling. The dark band across the bottom of the panels is caused by a shadow

The postflight photograph was taken in the SAEF II at KSC prior to experiment
removal from the LDEF. The originally white paint dot on clamp blocks at the
center of the upper tray flange and at each end of the bottom tray flange are
an off-white or light tan color. Paint on the clamp blocks located at each end
of the lower tray flange has been exposed to a greater atomic oxygen flux than
paint on the upper flange clamp block and appears to be less contaminated and
therefore brighter. The pink and the greenish-gray tints on the two (2) debris
panels are a by-product of the chromic anodize coating process and not
attributed to contamination and/or exposure to the space environment. The two
(2) white spots in the lower left quadrant of the left debris panel appear to
be debris impact craters. The light band along the right side and across the
bottom of the panels is caused by light reflecting from the tray sidewalls.

The postflight photograph of the integrated tray (D02) was taken in the
Operations and Checkout (O&C) building after the LDEF was transferred from
the KSC Payload Canister to the LDEF Assembly and Transport System (LATS).

The Space Debris Impact Experiment has many impact craters that can be seen on
the detector panels. The craters show as white dots against the brownish/gray
surface color of the detector panels. The faint pink and green tints on the
detector panel surface were produced during the chromic anodize process and are
not a result of exposure to the space environment.

The flight photograph was taken after the LDEF was retrieved and prior to
berthing in the orbiter cargo bay.

The Space Debris Impact Experiment consists of a three sixteenth (3/16) of an
inch thick chromic anodized aluminum panel mounted in a three (3) inch deep
LDEF experiment tray. The side of the plate exposed to the LDEF interior is
painted with Chemglaze Z-306 flat black paint over a Chemglaze 9924 wash

magnetic stainless steel fasteners. The panel coatings, a thin layer of chromic
anodize facing out and the Chemglaze Z-306 black paint facing the LDEF
interior, contribute significantly to thermal control of the LDEF spacecraft.

The panels appear to have a light tan tint when compared to the pre-launch
photograph. The debris panels are mounted in the bottom of the tray and the
shadow of the tray sides appears as a dark border along the right  side and
bottom edges of the panels. No impact craters are visible under the existing
lighting conditions.

The postflight photograph, taken prior to removal of the experiment trays from
the LDEF, again shows a significant difference in the color of the paint dots
on the experiment tray clamp blocks. The direction and intensity of the
artifical light source has caused hot spots and reflections that tend to
wash-out the brown stain on the aluminum structure.

The Space Debris Impact Experiment panels have a clean washed-out look that is
attributed to the lighting. The center panel has a pink tint and the end panel
has a green tint as they appeared in the pre-launch photograph. The finger
prints seen on the flight photograph are not visible but a faint shadow of the
palm print can be seen. With the change in direction of the light source, the
panel serial numbers and the location of impacts can not be determined.

Photo, Description==
The flight/on-orbit photograph of the D06 integrated tray was taken from the
Orbiter aft flight deck during the LDEF retrieval, while the spacecraft was
attached to the remote manipulator system. During the mission, the tray surface
was at an angle of approximately eighty-two (82) degrees to the orbital
velocity vector and therefore exposed to a higher atomic oxygen flux than if it
had been parallel with the velocity vector. Note the difference in color of the
paint dots on tray clampblocks; white dots along the top edge, a light tan
color on the center dot and a dark brown stain on the dots along the bottom of
the photograph.  The dots near the top of the photograph are adjacent to
experiment location D07 and are exposed to a higher atomic oxygen flux than
those adjacent to experiment location D05. Impacts of  atomic oxygen with a
surface tends to scrub away contamination from the that surface and leave it a
much cleaner.

The two (2) Space Debris Impact Experiment detector plates,  located in the
center and left end sections of a three (3) inch deep experiment tray, show
fingerprints and a palm print that occurred during installation of the panels
into the tray. These prints are not visible on the prelaunch photograph. The
light angle is such that the panel serial numbers, stamped in the upper left
corner of the each panel, can be seen. The grazing light angle also makes
numerous impact craters visible that would not be easily detectible if the
light source was perpendicular to the tray surface. When comparing the flight
photograph with the prelaunch photograph, A switch in panel colors can be
seen.  The flight tray has a center section panel with a green tint and an end
section panel with a pink tint. The opposite is seen in the prelaunch tray
photograph. The center section panel has the pink tint and the end section
panel is pale green. No definitive answer has been determined for the visual
changes.

The Space Debris experiment consist of two (2) one third (1/3rd) tray anodized
aluminum detector plates. The chromic anodize on the experiment detector
plate is not an experiment requirement but is used as a major contributor to
the passive thermal control of the LDEF. The green and/or pink tint seen on
the detector plates is produced by the chromic anodizing process and has no
impact on the experiment objectives or data analyses. The Space Debris
experiment is mounted to the aluminum tray structure with nonmagnetic
fasteners.

The postflight photograph was taken in the SAEF II at KSC prior to experiment
removal from the LDEF. The originally white paint dot on clamp blocks around
the periphery of the experiment tray show the results of contamination and
exposure to the space environment. The variation in color, from off-white along
the top flange to brown at other locations, is attributed to variations in the
atomic oxygen flux intensity. A surfaces exposed to a higher intensity of
atomic oxygen flux will have less contamination due to  the scrubbing or
cleaning action that occurs when the atomic oxygen molecules impact that
surface.

The pink and the greenish-gray tints on the two (2) debris panels are
by-product of the chromic anodize coating process and not attributed to
contamination and/or exposure to the space environment. The light band along
the bottom of the panels is caused by light reflecting from the tray
sidewalls.

significantly by the blue reflection. The fingerprints along the lower edge of
the debris panels are from handling during experiment assembly.

The flight photograph was taken while the LDEF was attached to the Orbiter's
RMS arm prior to berthing in the Orbiter's cargo bay. The paint dots on clamp
blocks located at the center of the lower tray flange, the center of the left
tray flange and the right end of the upper tray flange have changed little from
their original white color. Discolorations are visible on the upper, left
side and lower experiment tray flanges.

The Space Debris Impact Experiment consists of a three sixteenth (3/16) of an
inch thick chromic anodized aluminum panel mounted in a three (3) inch deep
LDEF experiment tray. The side of the plate exposed to the LDEF interior is
painted with Chemglaze Z-306 flat black paint over a Chemglaze 9924 wash

interior, contribute significantly to thermal control of the LDEF spacecraft.

A portion of the pink and greenish-gray tint on the two (2) debris panels are
by-products of the chromic anodize coating process, however, part of the
intensity can be attributed to reflections of the blue sky. The vertical
streaks on the debris panel are by-products of chromic anodizing that have been
enhanced by the blue reflection. The light band along the vertical edge of the
left debris panel is a reflection from the tray sidewall.

The postflight photograph was taken in the SAEF II at KSC prior to experiment
removal from the LDEF. The originally white paint dot on clamp blocks at the
left end of the lower tray flange and at the center of the upper and right tray
flanges have changed slightly to an off-white color.

The pink and the greenish-gray tints on the two (2) debris panels are
by-product of the chromic anodize coating process and not attributed to
contamination and/or exposure to the space environment. The vertical streaks
observed on the debris panels in the flight photograph are no longer visible
since the blue sky reflection is not present. Debris from other experiments,
significantly degraded during the mission, are visible on the lower experiment
tray sidewall at its intersection with the lower edge of the debris panels.
Other experiment debris, visible as dark specks, can be seen at the
intersection of the debris panel outer edges and the tray sidewalls. The light
band along the sides and across the bottom of the panels is caused by light
reflecting from the tray sidewalls.

Photo, Description==
The postflight photograph was taken in the SAEF II at KSC prior to experiment
removal from the LDEF. The originally white paint dot on clamp blocks around
the perifery of the experiment tray show the results of contamination and
exposure to the space environment. The variation in color, from off-white along
the top flange to brown at other locations, is attributed to variations in the
atomic oxygen flux intensity. A surface exposed to a higher intensity of atomic
oxygen flux will have less contamination due to  the scrubbing or cleaning
action that occurs when the atomic oxygen molecules impact that surface.

The pink and the greenish-gray tints on the two (2) debris panels are
by-product of the chromic anodize coating process and not attributed to
contamination and/or exposure to the space environment. The dark vertical
streaks seen on the left debris panel in the flight photographs are still visi-
ble, but are much lighter since the blue sky reflection is not present. The
same can be said for the two (2) discolorations, they are still visible but
much lighter. The light band along the sides and across the bottom of the
panels is caused by light reflecting from the tray sidewalls.

The flight photograph was taken while the LDEF was attached to the Orbiter's
RMS arm prior to berthing in the Orbiter's cargo bay. The color of the paint
dot on the clamp block located at the top right of the upper tray flange has
changed to a light tan from its orginal white color. Contamination has caused
the white paint dot on another tray clamp block, center left, to turn brown.

The Space Debris Impact Experiment consists of a three sixteenth (3/16) of an

The flight photograph was taken while the LDEF was attached to the Orbiter's
RMS arm prior to berthing in the Orbiter's cargo bay. A combination of the
space environment and contamination has caused the paint dot on the clamp
blocks located at the centers of the upper tray flange and the right tray
flange and at the left end of the lower flange to change from their original
white color to dark brown.

The Space Debris Impact Experiment consists of a three sixteenth (3/16) of an
inch thick chromic anodized aluminum panel mounted in a three (3) inch deep
LDEF experiment tray. The side of the plate exposed to the LDEF interior is
painted with Chemglaze Z-306 flat black paint over a Chemglaze 9924 wash

magnetic stainless steel fasteners. The panel coatings, a thin layer of chromic
anodize facing out and the Chemglaze Z-306 black paint facing the LDEF
interior, contribute significantly to thermal control of the LDEF spacecraft.

The greenish-gray and pink tints on the two (2) debris panels are a by-product
of the chromic anodize coating process and not attributed to contamination
and/or exposure to the space environment. Finger prints seen along the center
edges of the debris panels indicate improper preflight handling/cleaning.

The postflight photograph was taken in the SAEF II at KSC prior to experiment

center of the lower tray flange has been exposed to a greater atomic oxygen
flux than paint on the clamp blocks located at the center of the left flange
and at the right end of the upper flange and appears to be less contaminated
and therefore brighter.

The pink and the greenish-gray tints on the two (2) debris panels are
by-product of the chromic anodize coating process and not attributed to
contamination and/or exposure to the space environment. The streaks on the
debris panels in the flight photographs are almost invisible since the blue sky

tray flanges have changed slightly to an off-white color.

The green tint on the two (2) debris panels is a by-product of the chromic
anodize coating process and not attributed to contamination and/or exposure to
the space environment. A light colored irregular shaped vertical streak is seen
on the right debris panel. The light band across the top and bottom edges of
the panels is caused by light reflecting from the tray sidewalls.

The Space Debris Impact Experiment consist of two (2) three sixteenth (3/16th)
inch thick chromic anodized aluminum panels mounted in a three (3) inch deep
peripheral LDEF experiment tray. The side of the panels exposed to the LDEF
interior are painted black with Chemglaze Z-306 flat black paint over a
Chemglaze 9924 wash primer. The panels are attached to the aluminum tray
structure with non-magnetic stainless steel fasteners. The panel coatings, a
thin layer of chromic anodize facing out and the Chemglaze Z-306 black paint
facing the LDEF interior, contribute significantly to thermal control of the
LDEF spacecraft.

The photograph shown is a photograph of a spare flight Debris experiment tray
and is used as a prototype for descriptive purposes only. An individual
photograph of each Debris Experiment tray was not taken prior to installation
of the tray on the LDEF.

The postflight photograph was taken in the SAEF II at KSC prior to experiment
removal from the LDEF. The originally white paint dot on clamp blocks at the
right end of the upper tray flange and at the center of the lower and left tray
flanges have changed slightly to an off-white color.

The pink and the greenish-gray tints on the two (2) debris panels are
by-product of the chromic anodize coating process and not attributed to
contamination and/or exposure to the space environment. The vertical streaks
observed on the right debris panel in the flight photograph are no longer
visible since the blue sky reflection is not present. Debris from other
experiments, significantly degraded during the mission, are visible on the
lower experiment tray sidewall at its intersection with the right tray
sidewall. A larger piece is located in the upper right corner on the right
debris panel.  Other experiment debris, visible as dark specks, can be seen at
the intersection of the debris panel outer edges and the tray sidewalls. The
light band along the sides and across the bottom of the panels is caused by
light reflecting from the tray sidewalls.

The flight photograph was taken while the LDEF was attached to the Orbiter's
RMS arm prior to berthing in the Orbiter's cargo bay. The paint dots on clamp
blocks located at the center of the lower tray flange, the center of the left
tray flange and the right end of the upper tray flange appear to have changed
little from their original white color.  A discolorations is visible on the
lower half of the right experiment tray flange.

The Space Debris Impact Experiment consists of a three sixteenth (3/16) of an
inch thick chromic anodized aluminum panel mounted in a three (3) inch deep
LDEF experiment tray. The side of the plate exposed to the LDEF interior is
painted with Chemglaze Z-306 flat black paint over a Chemglaze 9924 wash
primer. The panels are attached to the aluminum tray structure with non-
magnetic stainless steel fasteners. The panel coatings, a thin layer of chromic
anodize facing out and the Chemglaze Z-306 black paint facing the LDEF
interior, contribute significantly to thermal control of the LDEF spacecraft.

A portion of the greenish-gray tint on the two (2) debris panels are
by-products of the chromic anodize coating process, however, additional blue
can be attributed to reflections of the blue sky.  The vertical streaks on the
right debris panel are by-products of chromic anodizing that have been enhanced
by the blue reflection. The brown stains along the top edge of the right debris
panel appear to be fingerprints from prelaunch handling. Light colored spots or
discolorations are along the left side of the right debris panel. The light
band along the vertical edge of the left debris panel is a reflection from the
tray sidewall.

The post landing Interstellar Gas Experiment photograph was taken from the
Orbiter's cargo bay access hatch during post landing operations to prepare
the Orbiter for the ferry flight from the Dryden Flight Research Center to the
Kennedy Space Center.

A very light contamination stain is present on the experiment tray flanges and
on the most of the visible LDEF structure. The exception being the darker stain
on the structure adjacent to thermal covers that provide venting for the LDEF
interior. Both paint dots appear to be heavily coated with the brown
contamination stain. The color of the white thermal control paint on the IGE
has changed and now varies from off-white to a dark brown. The darker brown
areas on the experiment baseplate, around the grid voltage cable connectors,
appear to have come from contaminants flowing from inside the LDEF. A dark
stain area can be seen on the lower half of the tray's left sidewall and in the
lower left corner of the tray. A lighter stain coats portions of the experiment
baseplate and the outside of the canister housing. A beryllium copper collector
foil is clearly visible in the upper left canister housing as are the baffles
and reflected light from the fine wire mesh grid near the top of the canister
housing. Due to an experiment system malfunction, the canister collector foils
that are visible were exposed for the total mission.

experiment tray sidewall.

The pink tint on the debris panel is a by-product of the chromic anodize
coating process and not attributed to contamination and/or exposure to the
space environment. The light colored spots on the debris panel are from the
same abrasions observed on the flight photograph.

specimen (98-2cm specimen and 12-4cm specimen) located in the EECC. Both sets
of specimen are mounted in aluminum  base plates and are parially mask by a
thin aluminum cover plate with circular openings. The cover plates and the sup-
port structure are assembled with non-magnetic fasteners. Some exposed specimen
coatings have changed colors and three of the larger (4cm) specimen appear to
be severely degraded or missing.  The EECC is in the closed position and
specimen contained within cannot be viewed. The visible parts of the canister
consist of the larger anodized aluminum thermal cover attached to the canister
body and sun shield attached to the canister drawer faceplate. The silver
squares on the lower corners of the canister sun shield are pads of tape
installed prior to launch.

Photo, Description==
The flight photograph was taken from the Orbiter aft flight deck during the
LDEF retrieval and prior to the berthing of LDEF in the Orbiter's cargo bay.

The Advanced Photovoltaic Experiment (APEX) is an active experiment completely
self-contained in a 12 inch deep LDEF peripheral tray. The APEX includes 155
solar cells permanently mounted on 127 removable aluminum plates of 12
different sizes, an Eppley Type HF cavity radiometer, a Digital Solar Angle
Sensor, a dichroic mirror assembly, a 'night' or dark sensor, a row of 16
bandpass filters clamped over silicon solar cell sensors, two ultraviolet
exposure monitors and two solar concentrator cells with deposited aluminum (on
Kapton and Mylar foil) mirrors.  An aluminum sub-structure provides a mounting
surface for experiment components and controls the field of view of solar
cells. Two separate electronic systems and power sources were included, one for
the experiment  and data acquisition and one, the Experiment Power and Data
System (EPDS), for data processing and storage. The experiment structure was
painted with Chemglaze Z-306 flat black paint over a Chemglaze 9924 wash primer
and assembled with non-magnetic stainless steel fasteners. The tray flanges and
tray clamp blocks appear as prelaunch but white paint dots on tray clamp blocks
have a slight variation in color. The paint color on the upper-left clamp block
is white, but paint on the right-center and lower-center clamp blocks is
lightly discolored.

The APEX has a number of physical changes that are apparent. The Chemglaze
Z-306 black paint on the exposed surfaces have degraded badly leaving the
Chemglaze 9924 primer , a redish-brown color, clearly visible. The difference
in the amount of paint remaining may be a function of initial paint thickness,
as the plate covering the tray's center section was painted at a different time
than the other two plates. The small gold colored rectangular plate in the
upper right section of the tray, was fabricated from an aluminum alloy and
coated with a clear anodize. A light brown discoloration can be seen on the
solar cell mounting plates and on areas of the aluminum base structure. The
solar concentrator cells, located at the right end of the second slot from the
top, appear to be damaged or a large piece of debris has lodged in the slot.
Structural members of the experiment appear to be intact.

The postflight photograph was taken in SAEF II at KSC prior to removal of the
experiment tray from the LDEF.

The Active Optical System Component Experiment (S0050) contained 136 test
specimen located in a six (6) inch deep LDEF peripheral experiment tray. The
complement of specimen included optical and electro-optical components, glasses
and samples of various surface finishes. The experiment tray was divided into
six sections, each consisting of a 1/4 inch thick chromic anodized aluminum
base plate and a 1/16th inch thick aluminum hat shaped structure for mounting
the test specimen. The test specimen were typically placed in fiberglass-epoxy
retainer strip assemblies prior to installation on the hat shaped mounting
structure.  Five of the six sections were covered by a 1/8 inch thick anodized
aluminum sun screen with openings that allowed 56 percent transmission over the
central region. Two sub-experiments, The Optical Materials and UV Detectors
Experiment (S0050-01) consist of 15 optical windows, filters and detectors and
occupies one of the trays six sub-sections and The Optical Substrates and
Coatings Experiment (S0050-02 ) that includes 12 substrates and coatings and
two secondary experiments,The Holographic Data Storage Experiment (AO044)
consisting of four crystals of lithium niobate and ThePyroelectric Infrared
Detectors Experiment (AO135) with twenty detectors, are also mounted in the
integrated tray. The experiment structure was assembled with non-magnetic
stainless steel fasteners.

The experiment hardware appears to be intact with no apparent damage. The
excess blue color in the flight photograph is no longer present. The paint dots
on the tray clamp blocks, initially white, are brown and tray flanges appear to
have a light tan discoloration. The experiment sun screens and base plate also
appear to have the same discoloration. The exposed experiment test specimen and
their fiberglass-epoxy mountings appear to have survived the mission. The
fiberglass-epoxy mounting strip colors have changed from the typical
greenish-gray to a slate gray and the colors of the test specimen appear to be
much darker than in the prelaunch photograph.

The flight photograph was taken while the LDEF was attached to the Orbiter's
RMS arm prior to berthing in the Orbiter's cargo bay. The paint dots on clamp
blocks located at the centers of the upper and left tray flanges have changed
from their original white color to an off-white. Brown discolorations are
visible on the experiment trays left and lower flanges.

The Thermal Control Surfaces Experiment (TCSE) is completely self-contained in
a twelve (12) inch deep LDEF experiment tray and consist of the power and data
systems, a carousel, a pre-programmed controller and the sample materials.
The experiment structure is fabricated from aluminum alloys and assembled
using non-magnetic stainless steel fasteners. The photograph shows the carousel
sample mounting plate rotated into the open position and a thermal shroud that
covers the experiment structure and the power and data system components. The
aluminum sample mounting plate accommodates twenty five (25) active samples
mounted in calorimeters to thermally isolate the samples from the mounting
plate, twenty-four (24) passive samples and three (3) radiometers.  The thermal
shroud, an aluminum alloy sheet material that is thermally isolated from the
experiment structure, has an inside surface coated with black thermal paint
and an outside (exposed) surface covered with two (2) mil silver Teflon,
applied to the aluminum with Y966 acrylic adhesive.

The most obvious change is the color of the 2 mil silver Teflon surface on the
shroud. The original silver mirror-like surface now appears white with copious
amounts of a brown discoloration in a distinct pattern. The upper and  lower
triangular sections of the shroud have many irregular shaped black
discolorations and an areas where the adhesive appears to have failed. Changes
in color have occurred in both the active and passive samples. Note the top
four active coating samples located on the outer radii, two of the first
three, originally white, now appear brown and have significant damage. The
fourth coating sample from the top, originally black, appears to have eroded
away leaving only a trace of the paint and/or primer on the substrate. The
calorimeter outer edge appears to be deformed in the fourth from lower left
active sample location. The passive samples, located on the inner radii, appear
to have no physical damage ,however, some of the white paint samples now appear
brown or tan. The first and fourth sample from the top appear to have changed
from their original color to black and the fifth sample ,originally black, now
appears gold. The three radiometers appear to be intact with no apparent
physical damage.

Photo, Description==
The Fiber Optic Data Transmission Experiment (FODTE) flight photograph was
taken while the LDEF was attached to the Orbiter's RMS arm prior to berthing in
the Orbiter's cargo bay. The white paint dots on clamp blocks at each end of
the experiment tray lower flange appear to be discolored.

The FODTE occupies a six (6) inch deep LDEF peripheral tray and consist of an
aluminum internal support structure, four aluminum mounting plates, an
aluminum cover plate, ten fiber optic cable samples with connectors, aluminum
brackets and non-magnet fasteners required to assemble the experiment. Four
optical fiber cables (two black, one blue and one bright orange), each
configured in  the form of a planar, helix coil, are attached to the thermally
isolated mounting plates with black anodized aluminum clips cushioned with
silicone-rubber spacers. The four mounting plates are coated with a Catalac
off-white thermal control paint and the exposed surface of the cover plate is
painted with Chemglaze II A-276 white to meet  thermal control requirements.
Six additional coils of optical fiber cable samples, secured with nylon cable
ties, are located in the bottom of the tray, four below the mounting plates and
two below the cover plate.  Each sample terminates in connectors mounted in
brackets located in the tray bottom or on the backside of the thermally
isolated mounting plates.

The FODTE appears to be intact with no apparent physical damage. A flow pattern
of discoloration appears to the right of each fastener used to secure the
four mounting plates. Colors of two of the four exposed coils of fiber optic
cables have changed significantly. The cable located in the upper right corner,
originally a bright orange, appears to be dark blue and the cable in the lower
left position has faded from a light blue to a blue-gray color. The color of
the silicone-rubber spacers under the coil attach clips appears to have
changed from clear to brown. Two brown circular discolorations have appeared,
one on the lower edge of the mounting plate in the upper left  location and
one on the upper edge of the mounting plate in the lower right position. Dark
brown irregular shaped discolorations can also be seen along the lower edge and
on each of the vertical edges of the cover plate.

Photo, Description==
The Fiber Optic Data Transmission Experiment (FODTE) postflight photograph
was taken in the SAEF II at KSC after the experiment was removed from the LDEF.
The experiment trays lower flange has a light tan discoloration that is visible
in areas not protected by the tray clamp blocks. Dark brown discolorations can
be seen near the center of the tray left flange and on the upper and lower
flanges near the corners of the white cover plate. The tray sidewalls appear to
be heavily stained in corners, along the three areas adjacent to the white
cover plate and at the intersection of the sidewalls with the experiment sup-
port structure.

The FODTE occupies a six (6) inch deep LDEF peripheral tray and consist of an
aluminum internal support structure, four aluminum mounting plates, an
aluminum cover plate, ten fiber optic cable samples with connectors, aluminum
brackets and non-magnet fasteners required to assemble the experiment. Four
optical fiber cables (two black, one blue and one bright orange), each
configured in  the form of a planar, helix coil, are attached to the thermally
isolated mounting plates with black anodized aluminum clips cushioned with
silicone-rubber spacers. The four mounting plates are coated with a Catalac
off-white thermal control paint and the exposed surface of the cover plate is
painted with Chemglaze II A-276 white to meet  thermal control requirements.
Six additional coils of optical fiber cable samples, secured with nylon cable
ties, are located in the bottom of the tray, four below the mounting plates and
two below the cover plate.  Each sample terminates in connectors mounted in
brackets located in the tray bottom or on the backside of the thermally
isolated mounting plates.

The FODTE appears to be intact with no apparent physical damage. A flow pattern
of discoloration appears to flow in a downward direction from fasteners used
to secure the four mounting plates. The colors of two coils of the externally
mounted fiber optic cables have changed significantly. The cable located in
the lower  right corner, originally a bright orange, appears to be dark brown
and the cable in the upper left position has faded from a light blue to blue
gray in color.  The color of the silicone-rubber spacers under the coil attach
clips appears to have changed from clear to brown and to have discolored the
fiber coils in areas adjacent  spacers. Two brown circular discolorations,
one on the left edge of the mounting plate in the upper right location and one
on the right edge of the mounting plate in the lower left position, observed in
the flight photograph are still visible. Four dark brown areas of discoloration
are visible around openings to the tray interior that are located in the
vertical seam between the mounting plates. Dark brown irregular shaped
discolorations can also be seen along the vertical and upper edges of the cover
plate. An irregular shaped vertical stain on the upper right corner of the
cover plate, not observed in the flight photograph, is now visible.

The postflight photograph of the Low Temperature Heat Pipe Package (HEPP)
experiment was taken in the SAEF II at KSC prior to removal of the experiment
from the LDEF. The color of the white paint dots on three of the experiment
tray clamp blocks appears to be unchanged.

The Low Temperature Heat Pipe Package (HEPP) experiment occupies two 12 inch
deep LDEF experiment trays connected with an inter-tray wiring harness. The
HEPP Experiment tray, a peripheral tray modified to accommodate radiator
location and field of view  requirements, is located in the LDEF tray location
F12. The HEPP Power tray, an end corner tray, is located on the space end of
the LDEF in tray location H01. The experiment tray (F12) contains a Constant
ConductanceHeat Pipe, a Thermal Diode Low Temperature Heat Pipe, a radiator
coupled with a phase change material canister, the data acquisition and control
systems and the LDEF experiment power and data system (EPDS) for processing,
recording and storing experiment data. The HEPP EPDS is also used to record and
store thermal data from the CVCHPE (AO076) and the THERM (P0003) experiments.
Fiberglass standoffs and internal multilayer insulation (MLI) blankets ther-
mally isolated the experiment from the experiment tray and the LDEF interior.
The radiator and radiator shield panels located in the left half of the tray
were covered with silvered Teflon tape to provide the desired optical
properties. The outside of the HEPP, except the radiator shield panels and the
radiator, was covered with an aluminized Kapton multilayer insulation (MLI)
blanket with the outer Kapton layer coated with vapor deposited aluminum on one
side only. The two patches of thin film materials, part of an experiment byNASA
GSFC that consist of five patches of thirteen samples each and located at
three different  places on the LDEF (F09, F12 and H01), were attached to the
cover of the external thermal blanket with Kapton tape. The experiment was
assembled and mounted in the experiment tray with non-magnetic stainless steel
fasteners.

The upper and lower radiator shields appear to have fine cracks and/or
abrasions on the surfaces and are discolored by a brown stain. A darker brown
stain appears at the intersection of the end shield sections and in the lower
left corner where the silvered Teflon tape has pulled away and is hanging over
the LDEF structure. The area initially covered by the tape appears clean and is
outlined by a vertical line of discolored material. The external thermal
control blanket has sustained damage in the forms of cracks and/or tears near
its intersection with the radiator and overall appears more fragile than in the
prelaunch photograph. The lower patch of atomic oxygen experiment materials
has many severely degraded samples. Several of the materials have sections
eroded away and remain attached at only one end, others appear to be completely
gone or only fragments remain. The materials in the upper patch appear to have
a better survival rate but are eroded, wrinkled and have distorted shapes.
Discolorations that appear to be pieces of Kapton tape lay horizontally across
the lower third of the upper patch of materials and another piece lays
horizontally across the center of the lower patch of material samples.

The radiator and the radiator shields appear deep blue apparently due to the
lighting and the reflecting surface. The upper and lower radiator side shields
appear to be discolored by a brown stain that can be seen through the deep blue
color. The Teflon tape used to provide continuity between the side shield and
end shield surfaces appears to be loose and only secured at the outer edges.
The tape and the areas initially covered by the tape appear discolored. The
external thermal control blanket appears to be in good condition, however, the
lower patch of atomic oxygen experiment materials has many severely degraded
samples. Several of the materials have sections eroded away and remain attached
at only one end, others appear to be completely gone. The materials in the
upper patch appear to have a better survival rate but are wrinkled and have

The postflight photograph of the Low Tem perature Heat Pipe Package (HEPP)
power tray was taken in the SAEF II at KSC after an all up system checkout
with interfacing experiments and removal of the tray from the LDEF. An outline
of the experiment tray clamp blocks is clearly visible in the light brown stain
on the experiment tray flanges.

The Low Temperature Heat Pipe Package (HEPP) experiment occupies two 12 inch
deep LDEF experiment trays connected with an inter-tray wiring harness. The
HEPP Power tray, an end cor ner tray, occupies a location on the space end of
the LDEF in tray location H01 and the HEPP Experiment  tray, a peripheral tray,
is located in the LDEF tray location F12. The power tray (H01) consist of four
solar array panels, one nickel-cadmium (NiCd) battery, a Power System
Electronics (PSE) unit, protective thermal blankets that line the tray interior
and a thirty seven pound baseplate mounted on thermal isolators to provide a
thermally stable mounting for the bat tery and the PSE.  Thirteen strips of
thin film thermal control materials, part of an experiment by NASA GSFC that
consist of sixty-five samples located at three different LDEF tray locations
(H01, F09 and F12), were attached to the experiment tray flanges with Kapton
tape. The experi ment was assembled and mounted in the experiment tray with
non-magnetic stainless steel fasten ers.

The experiment hardware appears to be intact with no apparent changes other
than stains along outer edges of the solar arrays.  The light brown stains
observed along the upper edges of the solar array mounting plates and around
the outer edge of the baseplate in the flight photograph are not apparent in
the postflight photo. The atomic oxygen experiment thin film strips appear to
be in place with no apparent damage. The Kapton tape appears to be firmly
adhered to the tray flanges in all thirteen locations.

The prelaunch photograph provides a view of the two (2) experiments located in
a six (6) inch LDEF experiment tray. The A0187-02 is located in the right two
thirds (2/3rd) of the tray and the EECC containing the S1002 experiment
occupies the remaining section. The tan colored strips on the tray flanges are
protective coatings that are removed prior to tray testing.

S1002 - The Effects on Coatings and Solar Cells experiment is contained within
the Experiment Exposure Control Canister (EECC) that is located in the left one
third (1/3rd) of the experiment tray. The EECC hardware consists of the
housing, the drawer that contains the experiment samples, the drawer opening
and closing mechanism (a screw drive system) and chromic anodized aluminum
thermal covers that are seen in the photograph. The hardware is fabricated from
aluminum or non-magnetic steels and is assembled with non-magnetic stainless
steel fasteners. The canister will be opened in orbit after the LDEF has been
deployed, the Orbiter has departed and initial outgassing of materials on the
LDEF has occurred. The canister is programmed to close approximately nine (9)
months after opening and prior to the scheduled LDEF retrieval. Experiment
samples located in the EECC consist of Second Surface Mirrors (SSM), SSM with
Interference Filters (SSM/IF), SSM/IF with a Conductive Layer (SSM/IF/LS,
Optical Solar Reflectors (OSR), Quartz Crystal Microbalance (QCM), Coatings and
Solar Cell Modules of the types flown on the GEOS and OTS satellites.

The EECC is closed with the S1002 experiments inside. The EECC hardware is
intact and appears to be in very good shape. The material on the corners of the
thermal cover, near the center of the tray, is layers of tape used to blunt
corners of the cover that could possibly snag an astronaut's suit if brushed
during an EVA. The tape layers seem to have separated but are still attached
and remain in place. The brown stain coats the exposed tray sidewall, the base
plate in the tray bottom, the lead screw and the thermal covers. Two (2) Impact
craters are located near the center of the base plate, another is located
between the two (2) lower screws on the support rail at the right bottom edge
of the tray. An impact crater appears as a white dot on the darker background.
Additional craters are visible on the EECC aluminum thermal covers, the tray
flanges and the LDEF structure.

S1002 is the item located in the right one third section of the tray.

Details of the EECC containing the experiment cannot be defined due to the
glare of the lights on the aluminum surfaces. The brown stain is clearly
visible on the left end of the bottom tray flange.  Note the spring collar near
the lower end of the lead screw. The collar, pushed along the lead screw as the
door opens, is an indication that the EECC did open and close while in orbit.

The green tint on the two (2) debris panels is a by-product of the chromic
anodize coating process and not attributed to contamination and/or exposure to
the space environment. A light colored irregular shaped vertical streak is seen
on the right debris panel. The light band across the top and bottom edges of
the panels is caused by light reflecting from the tray sidewalls.

LDEF Experiment (M0002-02) is located in the lower one half (1/2) of the right
section of the tray. The tray flanges appear as prelaunch but the white paint
dots on tray clamp blocks have varying degrees of discoloration. The paint
color on the lower-center clamp block remained white, paint on the left-center
clamp block is lightly discolored and paint on the upper-right clamp block is
heavily discolored.

The Ion Beam Textured and Coated Surfaces (IBEX) experiment, located in the top
one half (1/2) of the right tray section, consist of a thin aluminum thermal
isolation plate. an adapter to raise the samples to the top of the experiment
tray, an aluminum mounting plate, an aluminum retainer plate and 36 sample
materials on one inch diameter disc. Six openings in the mounting plate, cov-
ered with a stainless steel mesh, are used to vent the experiment interior.
Twenty-seven of the sample materials used an ion source to etch, sputter
deposit or texture a surface to obtain the desired optical property or surface
conductivity and seven samples are commercial paints or commercially available
metallized thin films used for thermal control. Non-magnetic stainless steel
fasteners are used for the experiment assembly and for attaching the experiment
adapter plate to the tray structure. The experiment hardware appears to be
intact with no apparent damage and experiment samples appear to have only minor
changes. The IITRI S13G-LO white paint sample located to the right of the lower
left corner vent screen has changed to a light brown color and the material
sample located above the lower right corner vent screen is partially missing.
Other material samples appear in prelaunch condition.

The Transverse Flat-Plate Heat Pipe Experiment flight photograph was taken
while the LDEF was attached to the Orbiter's RMS arm prior to berthing in the
Orbiter's cargo bay. No change in the color of the white paint dots on
experiment tray clamp blocks is apparent.

The Transverse Flat-Plate Heat Pipe Experiment consist of three (3) transverse
flat heat-pipe modules , a power system for the heaters, a data acquisition
and storage system and  an aluminum support structure placed in a twelve (12)
inch deep LDEF experiment tray. The surface of the experiment exposed to the
space environment consist of the three heat pipe modules exterior surfaces,
silver Teflon, and the thermal blankets covering the aluminum mounting hardware
and openings between the hardware and the tray sidewalls. The raised surface at
the top of each heat pipe module is the fluid reservoir. Five thermocouples,
for monitoring the external surface temperature, are located on each module.

The specular surface of the silver Teflon has become diffuse and appears white.
Numerous impact craters, black specks, can be seen on the white surfaces of the
modules. There appears to be a light tan discoloration on the surfaces of all
three heat pipe modules. Two different types of discolorations can be seen at
the top end of the center heat pipe; a dark brown color to the left of  the
thermocouple and what appears as two multi-color irregular shaped patterns to
the right of the thermocouple. A square shaped light brown discoloration is
seen near the left edge of the left thermal blanket, approximately half way
between the tray bottom and center clamp blocks and also near the top of the
thermal blanket between the left heat pipe module and the center heat pipe
module.

The Balloon Materials Degradation experiment, located in the center one third
(1/3rd) tray section, consist of 38 polymer film specimen, in the form of
either thin film or reinforced tape, and 24 fibrous cord specimen. The ends of
each test polymer film specimen, approximately 1.0 inch wide and 6.0 inches
long, were secured between aluminum clamp strips that attached to aluminum
experiment mounting plates. The cord specimen, approximately 4.0 inches long,
are secured along the left and right edges of the experiment mounting plates in
a similar manner. The aluminum clamp strips and experiment  mounting plates
have a thermal coat of IITRI S13G-LO white paint. Non-magnetic stainless steel
fasteners are used for the experiment assembly and for attaching the experiment
mounting plate to the tray structure.

The thin film polymeric material samples in the Balloon Materials Degradation
experiment appear to have been severely degraded. All 26 of the unreinforced
thin film samples have curled edges, 12 samples appear to have failed in
tension and a significant portion of the 2 aluminized polymer samples appears
to be missing. The reinforced thin film polymer samples are discolored but
appear to have survived the mission intact . The IITRI S13G-LO white paint
appears to have a light tan discoloration in areas not covered by experiment
samples with some evidence that at least some of the discoloration occurred
after sample failure.

The photograph provides a view of the LDEF end support beam (ESB) scuff plates.
The scuff plates and the longeron payload trunnion guides installed in the
Orbiter cargo bay provide a mechanism for positioning a payload in the payload
retention latches in the Orbiter's cargo bay during berthing operations. The
paint scheme of bright yellow paint with black markings meets Orbiter
visibility requirements. Note the difference in the color of paint on the scuff
plates after the extended eposure to the space environment. The scuff plate on
the left was located on the ESB trunnion on the leading edge of LDEF, row 9,
and the color is essentially the same as prelaunch. The discolorations on the
yellow surface appears to be from postflight handling and are not attributed to
the space exposure. The scuff plate on the right was located on the trailing
edge of the LDEF, row 3, and has changed to a brown color. The main dif-
ference in the exposure environments of the two scuff plates was the atomic
oxygen flux.  The leading edge was exposed to the RAM and the maximum atomic
oxygen flux with the trailing edge being in the LDEF's wake and exposed to the
minimum atomic oxygen flux.

The postflight photograph was taken in the SAEF II at KSC after the experiment
was removed from the LDEF and the silvered Teflon thermal cover was removed
from the experiment tray.

The Seeds in Space Experiment (P0004-01) is one of three passive experiments
located in a 6 inch deep LDEF peripheral tray. The experiment consist of 2
million seeds of 120 different varieties, one sealed canister, two smaller
vented canisters, and a silvered Teflon thermal cover. Two other experiments,
the Space Exposed Experiment  Developed for Students (SEEDS) P0004-02 and the
Linear Energy Transfer (LET) Experiment (P0006), were companion experiments in
the tray. The experiment hardware was assembled and mounted in the experiment
tray with non-magnetic stainless steel fasteners. Areas of the experiment tray
flanges covered by the tray clamp blocks are unstained and clearly visible.

The sealed Seeds in Space Experiment canister, a base portion and a dome
portion, was machined from aluminum and  assembled together with a butyl rubber
o-ring seal. The machined interior was approximately 4 inches deep with a 12
inch internal diameter, providing a volume of approximately 1/3 cubic foot.
the sealed canister was the center canister in the top row. The two vented
canisters were also aluminum. One canister, 4 inches in diameter and 4 inches
high, was mounted on the top side of the experiment tray at the lower right
corner of the large sealed canister. The other vented canister was rectangular
in shape and mounted on the bottom side of the tray, the side facing the LDEF
interior. The exterior surfaces of all canisters located on the top side of the
experiment tray were painted white with Chemglaze II A-276. The exterior
surface of the rectangular canister on the bottom side of the experiment tray
was coated with Chemglaze Z-306 flat black paint over a Chemglaze 9924 primer.
Thermal control was accomplished by placing the canisters on fiberglass

The flight photograph was taken from the Orbiter aft flight deck during the
LDEF retrieval and prior to the berthing of LDEF in the Orbiter's cargo bay.

The Space Exposed Experiment  Developed for Students (SEEDS) P0004-02 is one of
three passive experiments located in a 6-inch deep LDEF peripheral tray. The
experiment consist of 12.5 million Rutgers tomato seeds, five sealed canisters
and a silvered Teflon thermal cover. Two other experiments, the Seeds in Space
Experiment (P0004-01) and the Linear Energy Transfer (LET) Experiment (P0006),
were companion experiments in the tray. The experiment hardware was assembled
and mounted in the experiment tray with non-magnetic stainless steel fasteners.
The paint dots, originally white, located on experiment tray clamp blocks now
appear brown. The experiment tray flanges also appear to be discolored.

The sealed SEEDS canisters, 5 bases and 5 domes, were machined from aluminum
plate material and  assembled together with a butyl rubber o-ring seal. The
machined interior was approximately 4 inches deep with a 12 inch internal
diameter, providing an open volume of approximately 1/3 cubic foot  in each
canister. The 5 canisters were were mounted in the experiment tray along with a
similar canister containing the Seeds in Space Experiment. The exterior
surfaces of all canisters were painted white with Chemglaze II A-276 and
surfaces facing the LDEF interior were coated with Chemglaze Z-306 flat black
paint over a Chemglaze 9924 primer. Thermal control was accomplished by placing
the canisters on fiberglass isolators and covering the experiment tray with a
thin (5 mil) silvered Teflon specular cover secured with Velcro pads located on
each of the canister domes and on clips attached to the tray sidewalls.

The silvered Teflon thermal cover appears to be intact with no apparent damage.
The three dark spots appearing in a vertical row about a third of a tray width
from the right edge of the cover are the locations of three Velcro pads.

The prelaunch photograph was taken in SAEF II at KSC prior to installation of
the integrated experiment tray on the LDEF.

The Linear Energy Transfer (LET) Experiment (P0006) is one of three passive
experiments located in a 6 inch deep LDEF peripheral tray. The experiment
consist of two types of  detectors, thermal luminescence and track type,
assembled in a sealed container. Two other experiments, the the Seeds in Space
Experiment (P0004-01) and the Space Exposed Experiment  Developed for Students
(SEEDS) P0004-02  were companion experiments in the tray. The experiment
hardware was assembled and mounted in the experiment tray with non-magnetic
stainless steel fasteners and thermally protected by a silvered Teflon thermal
cover.

The sealed Linear Energy Transfer (LET) Experiment container was machined from
aluminum and assembled together with a Buna-N o-ring seal. The container,
approximately 6 inches in diameter and 4.5 inches high, was mounted on the top
side of the experiment tray and  painted white with Chemglaze II A-276. Thermal
control was accomplished by placing the canister on fiberglass isolators and
covering the experiment tray with a thin (5 mil) silvered Teflon specular cover
secured with Velcro pads located on each of the P0004 canister domes and on
clips attached to the tray sidewalls. The apparent brown discoloration in the
approximate center of the silvered Teflon cover is a reflection from the
surrounding area and not an actual stain.

The Space  Debris Impact Experiment con sists of a three sixteenth (3/16) of an
inch thick chromic anodized aluminum panel mounted in a three (3) inch deep
LDEF experiment tray. The side of the plate exposed to the LDEF interior is
painted with Chemglaze Z-306 flat black paint over a Chemglaze 9924 wash
primer. The panels are attached to the aluminum tray structure with
non-magnetic stainless steel fasteners. The panel coatings, a thin layer of
chromic anodize facing out and the Chemglaze Z-306 black paint facing the LDEF
interior, contribute significantly to thermal control of the LDEF spacecraft.

The postflight photograph was taken in SAEF II at the KSC after the experiment
was removed from the LDEF.  A brown discoloration can be seen on the upper tray
flange and a lighter discol oration on the lower tray flange not covered by the
experiment tray clamp blocks. Irregular shaped tan discolorations are also
visible on the  experiment tray sidewall with a darker stain in the right tray
corners

The post landing photograph of the Low Tempera ture Heat Pipe Package (HEPP)
experiment  was taken from the Orbiter's cargo bay access hatch during post
landing operations to prepare the Orbiter for the ferry flight from the Dryden
Flight Research Center to the Kennedy Space Center.

The white paint dots on the center clamp blocks of the experiment trays right
flange and upperer flange appear to be discolored. The discoloration diminishes
as as the distance from the vent area of the thermal shields increases. The
right and upper tray flanges also appear to be discolored.  Finger prints are
visible on the thermal panels in the vicinity of the panel mounting fasteners.

The Low Temperature Heat Pipe Package (HEPP) experiment occupies two 12 inch
deep LDEF experiment trays connected with an inter-tray wiring harness. The
HEPP Power tray, an end cor ner tray, occupies a location on the space end of
the LDEF in tray location H01 and the HEPP Experiment  tray, a peripheral tray,
is located in the LDEF tray location F12. The power tray (H01) consist of four
solar array panels, one nickel-cadmium (NiCd) battery, a Power System
Electronics (PSE) unit, protective thermal blankets that line the tray interior
and a thirty seven pound baseplate mounted on thermal isolators to provide a
thermally stable mounting for the bat tery and the PSE.. Thirteen strips of
thin film thermal control materials, part of an experiment by NASA GSFC that
consist of sixty-five samples located at three different LDEF tray locations
(H01, F09 and F12), were attached to the experiment tray flanges with Kapton
tape. The experi ment was assembled and mounted in the experiment tray with
non-magnetic stainless steel fasten ers.

The experiment hardware appears to be intact with no apparent changes other
than stains along outer edges of the solar arrays. Light brown stains are
visible along the upper edges of the solar array mounting plates with faint
traces of a lighter colored stain around the outer edge of the base plate. The
atomic oxygen experiment thin film strips appear to be in place with only minor
dam age. The samples in the upper left corner of the tray appear to be
degraded. The Kapton tape appears to be loose in several locations, the sample
in the trays lower left corner and the center sample on the right tray flange.
In other areas the tape appears to be firmly adhered to the tray flanges.

The postflight photograph was taken in SAEF II at KSC prior to removal of the
experiment tray from the LDEF.

The Holographic Data Storage Crystals for LDEF Experiment (AO044) consist of
four crystals of lithium niobate, three crystals contain recorded holograms and
one crystal is an unrecorded control sample. The Holographic Data Storage
experiment is an integral part of the Active Optical System Component
Experiment (S0050) that contains 136 test specimen and is located in a six (6)
inch deep LDEF peripheral experiment tray. The experiment tray is divided into
six sections, each consisting of a 1/4 inch thick chromic anodized aluminum
base plate and a 1/16th inch thick aluminum hat shaped structure for mounting
the test specimen. The test specimen are typically placed in fiberglass-epoxy
retainer strip assemblies prior to installation on the hat shaped mounting
structure.  Five of the six sections are covered by a 1/8 inch thick anodized
aluminum sun screen with openings that allowed 56 percent transmission over the
central region. Two subexperiments, The Optical Materials and UV Detectors
Experiment (S0050-01) consist of 15 optical windows, filters and detectors and
occupies one of the trays six sub-sections and The Optical Substrates and
Coatings Experiment (S0050-02 ) that includes 12 substrates and coatings and a
secondary experiment, ThePyroelectric Infrared Detectors Experiment with twenty
detectors, are also mounted in the integrated tray. The experiment structure
was assembled with non-magnetic stainless steel fasteners.

The experiment hardware appears to be intact with no apparent damage. The
excess blue color in the flight photograph is no longer present. The paint dots
on the tray clamp blocks, initially white, are brown and tray flanges appear to
have a light tan discoloration. The experiment sun screens and base plate also
appear to have the same discoloration. The exposed experiment test specimen and
their fiberglass-epoxy mountings appear to have survived the mission. The
fiberglass-epoxy mounting strip colors have changed from the typical
greenish-gray to a slate gray and the colors of the test specimen appear to be
much darker than in the prelaunch photograph.

Photo, Description==
The flight photograph of the Ultra Heavy Cosmic Ray Experiment (UHCRE) was
taken while the LDEF was attached to the Orbiter's RMS arm prior to berthing in
the Orbiter's cargo bay. The white paint dots on the center clamp blocks of the
experiment trays left flange and lower flange appear to be discolored by a dark
brown stain.

The UHCRE detectors were  contained in 16 peripheral LDEF trays with at least
one UHCRE tray located on each row of the LDEF except row 3, row 9 and row 12.
Each tray contains three cylindrical aluminum pressure vessels with an
integral aluminum support structure. Each cylinder is filled with an Eccofoam
insert that houses 4 UHCRE detector stacks. Each stack consist of layers of
Lexan polycarbonate sheets (approximately 70) interleaved with several thin
sheets of lead.  Forty-seven of the 48 pressure vessels were pressurized to 1.0
bar of a dry gas mixture (oxygen, nitrogen and helium) and sealed. One of the
units was left unsealed in order to investigate the effects of the vacuum
environment on the detector materials. Thermal control was accomplished by
attaching an aluminized Kapton thermal cover on the tray bottom (the Kapton
facing the LDEF interior), placing the aluminum cylinder support structure on
thermal isolators and covering the experiment with a thin (5 mil) silvered
Teflon thermal cover. The silvered Teflon cover was supported by an aluminum
frame,  an integral part of the experiment structure, and held in place by
Velcro pads selectively located on the frame and on the back of the cover. The
copper colored strip extending over the trays upper flange is a copper coated
pressure sensitive tape used to provide an electrical ground between the
experiments thermal cover and the LDEF structure.

The UHCRE thermal cover appears to be specular and intact with no apparent
damage but is more taut than in the prelaunch photograph. The wrinkled spots on
the thermal cover are areas where Velcro pads are bonded to the backside of the
cover. The scalloped effect around the cover edges occurs between the cover
attach points. The ground strap appears to be in place with no visible
damage.

honeycomb pressure cover and the main stack of CR-39 used to detect cosmic rays
mounted in an aluminum housing. The four modules are identi cal in materials
and construction. The exposed surface of each module is a white paint overcoat,
Chemglaze II A-276, that has been applied to the top layer, aluminized kapton,
of a multi-layer thermal blanket. The frame around each of the four modules, a
Z shaped aluminum structure, is covered with a silverized Teflon film secured
with 3M Y966 acrylic transfer tape. The 3M Y966 transfer tape on a siliverized
Teflon film is also used to attach the four edges of the multi-layer thermal
blankets to the modules frame. The combination of the silverized Teflon and the
white paint provides the appropriate optical properities needed to meet
experiment thermal require ments.

Photo, Description==
The flight photograph of the Heavy Ions in Space Experiment was taken from the
Orbiter's aft flight deck during LDEF retrieval operations. A light coating of
the stain can be seen on the tray flange adjacent to the American flag.

The photograph shows four (4) experiment modules mounted in the LDEF provided
end center experiment tray.An experiment module consist of the thermal cover, a
top stack of Lexan sheets for detecting low-energy ions,  a honeycomb pressure
cover and the main stack of CR-39 used to detect cosmic rays mounted in an
aluminum housing. Three modules are identical while the fourth module has been
divided into four smaller units that allows the use of pressure covers with a
lower energy threshold to Ion penetration. The exposed surface of each module
is a white paint overcoat, Chemglaze II A-276, that has been applied to the top
layer, aluminized Kapton, of a multilayer thermal blanket. The frame around
each of the four modules, a Z shaped aluminum structure, is covered with a
silverized Teflon film secured with 3M Y966 acrylic transfer tape. The 3M Y966
tape on a silverized Teflon film is also used to attach the multi-layer thermal
insulation blankets to the modules frame. The combination of the silverized
Teflon and the white paint provides the appropriate optical properities
needed to meet experiment thermal requirements.

Extensive damage occurred to the experiment's multi-layer thermal blankets
during the LDEF mission, prior to retrieval operations. It appears that the
tape used attach the thermal blankets to the structure failed in tension. When
the bond joint released along two (2) sides, the tension was releaved and the
remaining tape continued to hold the blanket to the structure through out the
rest mission and the post-flight operations. The outside blanket surfaces that
were originally white are now coated with a glossy dark brown stain thought to
be from contamination and/or the products of material outgassing. The golden
colored material in the three (3) full modules are the top sheets of Lexan
detector stacks held in place by the aluminum Z shaped structure. The deep rich
chocolate colored sections visible in one half (1/2) of the other module is
also the top layer of detector sheets underneath support straps.
