Payload:
  Space Station Assembly Flight ISS-09-6A (Raffaello MPLM-1, Racks/SLP, Canadarm2(SSRMS,SPDM), LCA,RU, UHF Antenna)

Mission Objectives:  

 The highest priority objectives of the flight are the installation,
 activation and checkout of the robotic arm on the station. The
 operation of the arm is critical to the capability to continue
 assembly of the International Space Station and to attach a new
 airlock to the station on the subsequent shuttle flight, mission
 STS-104, planned for launch in June.  A final component of the
 Canadian Arm is the Mobile Base System (MBS) that will be installed
 onboard the station during the UF-2 STS-111 flight.

 Other major objectives for Endeavour's mission are to berth the
 Raffaello logistics module to the station, activate it, transfer
 cargo between Raffaello and the station, and reberth Raffaello in the
 shuttle's payload bay. Raffaello is the second of three Italian Space
 Agency-developed multi-purpose logistics modules to be launched to
 the station. The Leonardo module was launched and returned on the
 last shuttle flight, STS-102, in March.

 Remaining objectives include the transfer of other equipment to the
 station such as an Ultra-High Frequency communications antenna and a
 spare electronics component to be attached to the exterior during
 space walks.  Finally, the transfer of supplies and water for use
 aboard the station, the transfer of experiments and experiment racks
 to the complex, and the transfer of items for return to Earth from
 the station to the shuttle are among the objectives.

 Endeavour also is planned to boost the station's altitude and perform
 a flyaround survey of the complex, including recording views of the
 station with an IMAX cargo bay camera.


Launch:
  April 19, 2001 2:41 p.m. EDT.  Launch occured ontime at the
opening of a 4.5 minute launch window.  SSME cutoff ontime
at T+8 minutes 39 seconds.  Shuttle liftoff weight 4,521,931 lbs.

  On Tuesday, April 17, 2001, engineers completed troubleshooting a
faulty lighting dimmer switch on the flight deck of the crew
module. The electrical box was successfully replaced overnight
following cryogenic loading. Loading of the orbiter's onboard
cryogenic storage tanks is now complete, and technicians are working
no further problems at the pad at this time.
(Reference KSC Shuttle Status 4/18/2001)
  
  On Monday, April 16, 2001, the launch countdown for mission STS-100
began at 6 p.m. as scheduled. Preparation continues toward a launch of
Space Shuttle Endeavour and the seven-member flight crew at 2:41
p.m. Thursday.  The orbiter's onboard cryogenic storage tanks were
then loaded for flight and the orbiter midbody umbilical unit demated.
Loading operations began about one hour late, allowing engineers to
troubleshoot a lighting dimmer switch in the crew module before
clearing the pad.  (Reference KSC Shuttle Status 4/17/2001)


  Space Shuttle Endeavour rolled out of the Vehicle Assembly Building
today at about 9:50 a.m. Solid rocket booster closeout inspections
slightly delayed first motion, and Endeavour is now expected to arrive
at the pad before 4 p.m. Once at the pad, routine launch pad
validations commence, verifying all vehicle and facility interfaces.
(Reference KSC Shuttle Status 3/22/2001)

  Shuttle orbiter Endeavour departed OPF bay 2 Saturday at about 9:26
  a.m. headed for the VAB. Orbiter and external tank mating activities
  are under way and the Shuttle Interface Test will conclude on
  Wednesday. The full Space Shuttle stack is scheduled to roll out of
  VAB high bay 3 at 7 a.m. on Thursday, March 22, and should arrive at
  Launch Pad 39B by about 1 p.m.

  STS-100 Flight Day 1 Highlights:

 On Thursday, April 19, 2001, 3:30 p.m. CDT, STS-100 MCC Status Report #1
reports:

  The Shuttle Endeavour lifted off from the Kennedy Space Center this
afternoon, carrying a multi-national crew and a complex Canadian-built
robotic arm to the International Space Station (ISS).

  Commander Kent Rominger, Pilot Jeff Ashby and Mission Specialists
Chris Hadfield of the Canadian Space Agency, John Phillips, Scott
Parazynski, Umberto Guidoni of the European Space Agency and Yuri
Lonchakov of Rosaviakosmos blasted off on time from Launch Pad 39-A at
1:41 p.m. Central time as the ISS sailed over the Indian Ocean south
of India. Aboard the station, Expedition Two Commander Yury Usachev
and Flight Engineers Jim Voss and Susan Helms were told of Endeavour's
launch as it lifted off from the pad. Approximately 20 minutes later,
the three crew members took a few minutes out from routine maintenance
work and preparations for Endeavour's arrival to watch a video feed of
the launch uplinked to them by ISS flight controllers in Houston
through the station's KU-band communications system.

  Less than nine minutes after launch, Endeavour had reached its
preliminary orbit and began its pursuit of the station for a docking
Saturday morning. The seven astronauts began to configure systems for
on-orbit operations and opened the shuttle's cargo bay doors before
the start of an eight-hour sleep period tonight at 6:41 p.m. Central
time.

  Aboard the ISS, all systems continue to function normally as
Usachev, Voss and Helms ready the complex for their first visitors
since beginning their expedition one month ago. On Monday, a Russian
Progress resupply vehicle was jettisoned from the aft docking port of
the Zvezda module, enabling the station crew to undock its Soyuz
return capsule from the nadir port of the Zarya module yesterday and
fly it to a redocking with Zvezda in a 21-minute maneuver. That
cleared the Zarya docking port for the arrival of the Soyuz rotation
"taxi" crew at the ISS later this month. The taxi crew will
deliver a fresh Soyuz capsule for the Expedition crew members's use
as an emergency return vehicle. The Soyuz vehicles need to be rotated
approximately every six months.

  Hadfield and Parazynski are scheduled to venture outside Endeavour
Sunday for the first of two scheduled space walks to unfold the huge
booms of the 57-foot-long Canadarm2 and to route power to the device,
which will be mounted on the Destiny Laboratory for future station
assembly work. Canadarm2 is scheduled to "walk off" its pallet and
attach itself to a grapple fixture on Destiny Monday, where it will
receive power, data and commanding from the Expedition crew operating
at robotic workstations inside Destiny.

  Housed in Endeavour's cargo bay is the Italian Space Agency-provided
Raffaello cargo module, which is carrying several tons of equipment
for the Expedition Two crew and racks of hardware for installation in
Destiny which will be used for scientific research in the
future. Raffaello, which is the second of three such logistics
modules, will be berthed to the ISS Monday so its contents can be
transferred to the station throughout the course of docked operations.

  Endeavour is circling the Earth in excellent shape as it flies in an
orbit inclined 51.6 degrees to either side of the Equator. The next
STS-100 mission status report will be issued Friday morning following
the wakeup call to Endeavour's astronauts from Mission Control, which
is scheduled at 2:41 a.m. Central time.

  STS-100 Flight Day 2 Highlights:

 On Friday, April 20, 2001, 3:00 a.m. CDT, STS-100 MCC Status Report #1
reports:

  The crew of the shuttle Endeavour worked this morning to prepare for
its Saturday docking with the International Space Station and for the
two planned spacewalks while there. The chase to catch up with the
waiting station and its Expedition Two crew continues with another in
the series of rendezvous maneuvers scheduled for about 5:30 this
morning.

  Endeavour is scheduled to dock with the station at 8:36 Saturday
morning to deliver the Canadian built high tech robotic arm, called
Canadarm2 and the Raffaello Multipurpose Logistics Module supplied to
the program by the Italian Space Agency. Raffaello contains equipment
and supplies for the station and its crew of Commander Yury Usachev,
and Flight Engineers Jim Voss and Susan Helms. It also brings two new
experiment racks for the station's U.S. laboratory Destiny.

  The Endeavour crew, Commander Kent Rominger, Pilot Jeff Ashby and
Mission Specialists Chris Hadfield of the Canadian Space Agency, John
Phillips, Scott Parazynski, Umberto Guidoni of the European Space
Agency and Yuri Lonchakov of Rosaviakosmos were awakened at 2:41
a.m. Friday by Then the Morning Comes by the musical group
Smashmouth. It was chosen for Phillips, making his first spaceflight.

  Today the shuttle crew will checkout three spacesuits and the
orbiter's robotic arm while rendezvous preparations include
installation of the centerline camera and extension of Endeavour's
Orbital Docking System ring. Another rendezvous engine burn is
scheduled shortly before the crew finishes today's activities.

  Space station crewmembers also will get ready for the
rendezvous. Later today they will prepare equipment for transfer to
the shuttle shortly after docking.

  Endeavour will bring the first visitors to the Expedition Two crew
since Discovery's departure last month. Shortly after
Endeavour's scheduled undocking and departure from the station on
April 28, a taxi crew is to arrive with a new Soyuz spacecraft. It
will replace the Soyuz, which launched the first crew toward the
station on Oct. 31, 2000. The Soyuz capsule has an on-orbit life of
about six months.

  Hadfield and Parazynski will conduct two spacewalks on Sunday and
Tuesday. The first will focus on installation of the 2-ton,
57-foot-long Canadarm2. The second is devoted to checkout of the arm
that will be instrumental in future space station assembly.

  Major systems aboard Endeavour and the International Space Station
continue to function well.  The next status report will be issued
later today, or as events warrant.

 On Friday, April 20, 2001, 5:30 p.m. CDT, STS-100 MCC Status Report #3
reports:

  The day on orbit was one of preparations as Endeavour's seven
astronauts got ready for tomorrow morning's scheduled arrival at
the International Space Station, and Sunday's planned space walk by
Mission Specialists Chris Hadfield and Scott Parazynski.

  Endeavour is scheduled to dock with the station at 8:32
a.m. Saturday although the crews will not greet each other until early
Monday. In preparation for tomorrow's rendezvous and docking,
Hadfield and Parazynski checked out the tools and hardware that will
be used during Endeavour's approach to the station, and Commander
Kent Rominger and Pilot Jeff Ashby installed a center-line camera in
the orbiter docking system.

  Rominger, Ashby and Flight Engineer John Phillips performed another
in a series of engine firings to refine Endeavour's approach to the
Station. As of 5 p.m., Endeavour was approximately 1,400 miles behind
and below the station, and closing that distance at the rate of about
171 miles every orbit of the Earth. Hadfield and Parazynski also
verified the operation of the spacesuits they will wear on two
scheduled space walks to install and activate the new Canadarm2
robotic arm.

  European Space Agency astronaut Umberto Guidoni began preparations
for the transfer of hardware and material from Endeavour to the
station and worked with Ashby in checking out the shuttle's robotic
arm to verify its operation. Yuri Lonchakov of Rosaviakosmos worked on
the middeck and filled two large water containers for later transfer
to the station.

  Endeavour's astronauts will go to sleep at 5:41 p.m. today,
awakening at 1:41 a.m. Saturday.  They will quickly begin the final
stages of their chase of the International Space Station.  The final
intercept burn is scheduled for 6:13 a.m., with docking at 8:32 a.m.,
as the two spacecraft fly overhead the Southeast coast of China,
northeast of Victoria, Hong Kong.

  Meanwhile, on the space station, Expedition 2 Commander Yury Usachev
and Flight Engineers Susan Helms and Jim Voss continued packing return
items and making sure their orbiting home is ready for the crew's
first visitors. Flight controllers report that the Russian
segment's carbon dioxide removal system is not working at its
highest rate, probably due to a clogged filter screen. The situation
poses no problems for the upcoming shuttle visit, but could lead to
increased use of backup lithium hydroxide removal systems after the
shuttle undocks and additional crew members arrive on a Soyuz taxi
flight. The station crew may be asked do some repairs on the unit on
Saturday.

  Otherwise, all major systems aboard Endeavour and the International
Space Station continue to function well. The next status report will
be issued Saturday morning after the crew is awake, or as events
warrant.

  STS-100 Flight Day 3 Highlights:

 On Saturday, April 21, 2001, 3:00 a.m. CDT, STS-100 MCC Status Report #4
reports:

  Space Shuttle Endeavour and its seven crewmembers began rendezvous
preparations shortly after 3 a.m. today, which should culminate in an
8:32 a.m. docking to the International Space Station, which will be
northeast of Hong Kong at an altitude of 240 miles. The shuttle is
bringing an advanced robotic arm, experiments and supplies to the
ever-growing science outpost.

  Before the undocking a week later, two space walks will have been
conducted and Raffaello, the second Multipurpose Logistics Module
provided by the Italian Space Agency, will have been unloaded and
reloaded after berthing to the station. The pressurized cargo carrier
 an orbital moving van  is bringing food, equipment and other
supplies, as well as two scientific experiment racks for the
U.S. laboratory Destiny.

  Endeavour will approach the station from behind and below. Commander
Kent Rominger and Pilot Jeff Ashby, assisted by the rest of the crew,
will fly the shuttle to a point about 600 feet directly below the
station. With the cargo bay pointed toward the station, they will fly
a quarter circle to a point about 300 feet ahead of the station. From
there they will begin a slow approach to the docking port at the
forward end of Destiny. Stationkeeping will begin at a distance of
about 30 feet to ensure a good alignment with the station's docking
target before Rominger resumes the approach at a speed of about one
foot every 10 seconds until docking.

  Kenny Loggins Danger Zone awakened Endeavour's crew
 Rominger, Ashby and Mission Specialists Chris Hadfield, John
Phillips, Scott Parazynski, Umberto Guidoni and Yuri Lonchakov 
early this morning. The song from the Top Gun soundtrack was played
for Rominger.

  The space station's crew was awakened shortly after 2 a.m. to
make final preparations for the shuttle's arrival. The Expedition
Two crew of Russian Commander Yury Usachev and astronauts Jim Voss and
Susan Helms has been aboard the station for more than a month since
assuming duty from the Expedition One crew on March 18.

  Though joined together, the two crews will not meet face-to-face
until early Monday, after the first space walk by Hadfield and
Parazynski. Endeavour's cabin pressure was lowered to 10.2 pounds
per square inch Friday afternoon in preparation for that space walk,
while the atmosphere inside the station remains a normal 14.7 psi.

  The first space walk, scheduled to begin about 6:20 a.m. Sunday,
will focus on installation of the station's robotic arm, called
Canadarm2. The space walkers also will install a UHF antenna on the
station's exterior. Their second space walk Tuesday, features
routing power and checking out the stations arm, which at 57.7 feet
long, is longer, more flexible and more powerful than the robotic arm
used by the shuttle fleet. If necessary, a third space walk could take
place Thursday.

  All systems are in good shape aboard both vehicles. The next status
report will be issued Saturday afternoon, or as events warrant.

 On Saturday, April 21, 2001, 3:30 p.m. CDT, STS-100 MCC Status Report #5
reports:

  With Commander Kent Rominger at the controls, Endeavour gently
docked with the International Space Station this morning as the two
spacecraft flew 243 miles over the southern Pacific Ocean, just
southeast of New Zealand. Docking occurred at 8:59 a.m. central time.

  Rominger, Pilot Jeff Ashby and Mission Specialists John Phillips,
Chris Hadfield, Umberto Guidoni, Scott Parazynski and Yuri Lonchakov,
briefly opened a hatch leading from the Shuttle into Pressurized
Mating Adapter-2, and retrieved a battery-powered drill for use on
Sunday's space walk. They also left behind some supplies that were
later retrieved by the station crew.  From the station side of the
hatch leading to PMA-2, flight engineer Jim Voss used a video camera
to film the smiling Shuttle crew members as they transferred four
water containers, computer equipment, some fresh food and film for the
IMAX camera.

  Though securely linked together, the two crews are not scheduled to
greet one another in person until early Monday, following the first
space walk to be conducted Sunday by Hadfield and Parazynski. Late in
their day, Hadfield and Parazynski were joined by space walk
coordinator Phillips in conducting some final checks of the suits and
hardware that will be used during tomorrow's planned 6  hour
space walk. The full crews on both vehicles then reviewed the
procedures to be followed throughout Hadfield and Parazynski's
space walk.

  This first space walk, scheduled to begin about 6:20 a.m., will
focus on installing the station's robotic arm, called Canadarm2,
and attaching an ultrahigh frequency (UHF) antenna on the station's
exterior. A second space walk is scheduled for Tuesday, and will focus
on establishing power connections and checking out the new 57.7
foot-long robotic arm.

  Expedition Two Commander Yury Usachev and Flight Engineer Susan
Helms verified the performance of the station's carbon dioxide
removal system, called Vozdukh, which had been operating in a slightly
degraded condition. The system started working normally overnight on
its own, and their checkout confirmed that it is operating within
normal parameters. Usachev, Helms and Voss also exercised and
continued preparations for the next week of joint operations with the
Shuttle crew.

  All systems are in good shape aboard both vehicles. The Station crew
will go to sleep at 5:31 p.m. today, followed 10 minutes later by the
crew of Endeavour. Mission Control will awaken the shuttle crew at
1:41 a.m. Sunday and the station crew will hear its wake-up alarm tone
at 2:01 a.m.

  The next status report will be issued Sunday morning, or as events
  warrant.

  STS-100 Flight Day 4 Highlights:

 On Sunday, April 22, 2001, 3:00 a.m. CDT, STS-100 MCC Status Report #6
reports:

  Now docked to the International Space Station, Endeavour and its
seven-member crew are preparing for the first of two planned space
walks set to begin about 6:20 this morning to install the orbiting
outpost's Canadian built robotic arm. Called Canadarm2, the
high-tech robotic arm is the most versatile ever flown in space.

  Shortly after crew wakeup, Canadian Space Agency astronaut Chris
Hadfield and Scott Parazynski began suiting up for the six and a half
hour space walk that marks the 19th devoted to the assembly of the ISS
and the 63rd in the history of the shuttle program. Hadfield will be
wearing a spacesuit with red stripes around the legs, while
Parazynski's suit will have no markings. John Phillips will serve
as the in-cabin quarterback for the space walk as Pilot Jeff Ashby and
European Space Agency astronaut Umberto Guidoni operate the
shuttle's robotic arm to install the new arm on the outside of the
Destiny laboratory.

  Hadfield and Parazynski will connect cables to give the arm power
and allow it to accept computer commands from the lab. They will
unbolt the arm from the pallet, then unfold its two booms and tighten
bolts to make them rigid. The space walkers also will install a UHF
antenna on Destiny.

  The Space station's Expedition Two crewmembers Jim Voss and Susan
Helms will power up the arm from the Robotic Work Station inside
Destiny, checking connections made by the space walkers.

  A second space walk is scheduled for Tuesday, and will focus on
establishing permanent power connections between the 57.7 foot-long
arm and station and running it through a thorough checkout.

  The shuttle crew was awakened earlier this morning by Canadian Stan
Roger's Take It From Day to Day played for Hadfield in
honor of the space walk  the first ever by a Canadian. The
Expedition Two crew was awakened shortly after the shuttle crew.

  Endeavour's cabin pressure will be increased to match that of the
station during the space walk leading toward opening of the hatches
between the shuttle and station Monday morning.  Endeavour docked with
the station at 8:59 a.m. Saturday followed soon after by entrance into
the docking port on the station to retrieve some tools for use during
today's space walk. The shuttle crew left behind four water
containers, fresh food, computer equipment and IMAX camera film for
the station crew.

  The next status report will be issued Sunday afternoon, or as events
  warrant.

 On Sunday, April 22, 2001, 3:30 p.m. CDT, STS-100 MCC Status Report #7
reports:

  Endeavour's astronauts extended the reach of the International
Space Station today, successfully installing a 57.7 foot long
Canadian-built robotic arm.

  Mission Control Houston recognized the importance of today's
activities sending up a congratulatory message from Canadian Astronaut
Steve MacLean and playing the Canadian anthem, Oh Canada
before the two space walkers  Scott Parazynski and Chris Hadfield
 floated back into Endeavour. Hadfield became the first Canadian
to conduct a spacewalk today as he worked to install the Canadian
built and provided Canadarm2 robotic arm.

  It really just opens the door to what all of us can be doing
here internationally, beginning to explore space as a planet, said
Hadfield.

  Parazynski and Hadfield spent 7 hours and 10 minutes working outside
the station, installing first an Ultrahigh Frequency (UHF) antenna
before turning their attention to the station's new robotic
arm. They floated out of Endeavour's airlock at 6:45 a.m. central
time and about two hours later had installed and deployed the UHF
antenna on the Destiny module of the station.

  With that complete, the two astronauts turned their attention to
installing the new station robotic arm. The main boom was deployed at
10 a.m. central, and a few minutes later, at 10:10 a.m. Hadfield and
Parazynski began unfolding the arm as Endeavour and the station flew
238 miles over the Atlantic Ocean.

  With the new arm secured in its pallet attached to the exterior of
the Destiny laboratory, Hadfield and Parazynski connected cables to
give the arm power and allow it to accept computer commands from
inside the lab. After unfolding the arm, they used a pistol grip tool
to properly secure a series of expandable fasteners that keep the
booms rigidized in position.  The two space walkers experienced some
difficulty ensuring an appropriate torque level had been placed on the
fasteners. By taking the pistol grip tool from automatic to manual
mode, Hadfield and Parazynski securely tightened the bolts in place,
completing their activities for the day and beginning to clean up the
payload bay before returning to Endeavour.

  Today's spacewalk, which concluded at 1:55 p.m., was the 19th
conducted to assemble the International Space Station. A second
spacewalk scheduled for Tuesday will focus on establishing permanent
power connections between the arm and station and performing a
thorough checkout.

  At 1:53 p.m., Flight Engineers Susan Helms and Jim Voss, on board
the station, commanded the first motion of the new station robotic arm
as they flew 242 miles over the Indian Ocean crossing the eastern
coast of Africa. All indications are that the arm operated perfectly
in this initial commanding.

  Tomorrow, just before 5:30 a.m., Helms and Voss will walk
the arm off the pallet and attach it to a grapple fixture on the
Destiny module. On Wednesday morning, they will use the station arm to
hand the pallet to the shuttle arm. In a procedure that will take
about 3  hours from start-to-finish, the pallet will be
transferred from one arm to the other and berthed back in
Endeavour's payload bay for return to Earth

  Endeavour's 50 foot-long robotic arm will be pressed into service
once again Monday morning as Pilot Jeff Ashby grapples the Italian
Space Agency-provided Raffaello logistics module and docks it
to the Unity module. Early Tuesday morning, the Expedition Two crew
 Voss, Helms and Commander Yury Usachev  will enter Raffaello
and begin transferring the supplies, equipment and experiment racks
loaded inside.

  After a busy day on orbit for both crews, the station crew will go
to sleep at 5:31 p.m., followed 10 minutes later by Endeavour's
crew. Mission Control will wake up Commander Kent Rominger, Ashby,
Mission Specialists John Phillips, Yuri Lonchakov, Umberto Guidoni,
Hadfield and Parazynski at 1:41 a.m. Monday. The station crew is
scheduled to wake up at 2:01 a.m.

  The next status report will be issued Monday morning, or as events
  warrant.

  STS-100 Flight Day 5 Highlights:

 On Monday, April 23, 2001, 3:00 a.m. CDT, STS-100 MCC Status Report #8
reports:

  The 10 astronauts and cosmonauts aboard the International Space
Station and the docked shuttle Endeavour are beginning a day that will
see the first opening of hatches linking the two
spacecraft. Highlights will include an impressive first step by the
station's new Canadarm2 and the berthing to the station of
Raffaello, the Italian-built logistics module.

  Hatch opening was set for 4 a.m. following a wakeup call from
Mission Control earlier this morning. Judy Collins Both Sides
Now for Pilot Jeff Ashby started the shuttle crews day.

  After transfer of equipment and supplies, the hatches will be closed
again a little after 2 p.m. so that the Shuttle cabin pressure can
once again be lowered to prepare for Tuesday's second
spacewalk. That spacewalk will focus on permanently powering the
station arm and doing further checkouts.

  The 57.7-foot arm was installed and unfolded Sunday during a 7 hour,
10 minute spacewalk by Scott Parazynski and Chris Hadfield. They also
installed a UHF antenna on the station's U.S.  laboratory
Destiny. It was the 19th spacewalk devoted to ISS assembly and the
63rd in the history of the shuttle program.

  After additional checkouts by Helms and Voss this morning, the arm
will walk off the Spacelab Pallet on which it was
launched. Its free end will be attached to a Power and Data Grapple
Fixture on Destiny, becoming the arm's base. That first step,
beginning a little after 5 a.m., will cover just over 24
feet. Wednesday morning, the station arm will hand the pallet to the
shuttle arm, to be berthed in Endeavour's cargo bay for return to
Earth.

  Endeavour's own 50-foot robotic arm, operated by Ashby, will
grapple the Raffaello logistics module in the cargo bay and dock it to
the Unity module. Its installation there should be complete about 10
a.m. today. Early Tuesday, the Expedition Two crew will begin
transferring the food, supplies, equipment and two experiment racks
for installation in Destiny from Raffaello to the station.

  Both crews are scheduled to end their day about 6:30
p.m. today. Both spacecraft are in excellent shape orbiting Earth
every 92 minutes at an altitude of 240 statute miles.

  The next status report will be issued this afternoon, or as events
  warrant.

 On Monday, April 23, 2001, 6:00 p.m. CDT, STS-100 MCC Status Report #9
reports:

  Two elements built by two countries adorn the International Space
Station (ISS) tonight after Endeavour's astronauts and the
Station's Expedition Two crew worked throughout the day to bring
the complex one step closer to an independent robotic capability.

  The new 57-foot long Canadian-built Canadarm2 robot arm took its
first step this morning, walking off a pallet mounted at the
top of the Destiny Laboratory to grab onto an electrical grapple
fixture on Destiny capable of providing data, power and telemetry to
the dexterous appendage.

  With Expedition Two Flight Engineer Susan Helms sending commands
from a workstation inside Destiny, the arm began to move off the
pallet at 6:13 a.m. Central time. Three hours later, after an
extensive checkout of all of its new joints, the arm affixed itself to
the Destiny grapple point where it will remain overnight in
preparation for its first active grappling of a payload --- the pallet
on which it was launched --- on Tuesday.

  As Canadarm2 was completing its work for the day, Mission Specialist
Scott Parazynski used Endeavour's slightly smaller robot arm to
latch onto the Italian-built Raffaello cargo module in the
Shuttle's payload bay. Raffaello was lifted out of the bay and was
attached to a docking port on the Station's Unity module at 11:00
a.m., setting the stage for Expedition Commander Yury Usachev, and
Flight Engineers Jim Voss and Helms to begin unloading three tons of
supplies beginning tomorrow. Parazynski was assisted by European Space
Agency astronaut Umberto Guidoni, who will take the lead in assisting
the Station crewmembers in the unloading of Raffaello and the
repacking of discarded items in the module later this week.

  Parazynski and Canadian Space Agency astronaut Chris Hadfield
prepared for their second spacewalk of the mission tomorrow by
checking out their tools and spacesuits. They are scheduled to emerge
from Endeavour's airlock around 8 a.m. Tuesday for a planned 6 
hour excursion to rewire the base of the newly installed Canadarm2 so
it can operate from its new home on the Destiny Laboratory, to remove
a communications antenna from Unity which is no longer needed and to
mount a spare electrical converter unit on a stowage platform on
Destiny for future Station use.

  Earlier today, Commander Kent Rominger, Pilot Jeff Ashby and Mission
Specialists John Phillips and Yuri Lonchakov of the Russian Aviation
and Space Agency led the way as hatches swung open between Endeavour
and the ISS at 4:25 a.m., allowing the ten crewmembers to greet one
another for the first time. Some supplies carried to the Station
aboard Endeavour were transferred throughout the day until the hatches
once again were closed at 2:26 p.m. after 10 hours of joint
operations. The hatch closure enabled the Shuttle's cabin pressure
to be lowered to support tomorrow's spacewalk.

  Near the end of the day, Rominger and Ashby supervised a one-hour
firing of Endeavour's jets to gently raise the orbit of the ISS
about 2  statute miles, from 237.8 statute miles to 240.3 statute
miles. Two more reboosts are planned on Wednesday and Thursday to
leave the Station at the correct altitude for the arrival of a
Russian-commanded taxi crew next week delivering a fresh Soyuz
return vehicle to the complex.

  Both crews are scheduled to end their day just after 6:30 p.m. and
will be awakened early Tuesday morning. Both spacecraft are in
excellent shape orbiting the Earth every 92 minutes.

  The next status report will be issued tomorrow morning after crew
wakeup, or sooner, if events warrant.

  STS-100 Flight Day 6 Highlights:

 On Tuesday, April 24, 2001, 4:00 a.m. CDT, STS-100 MCC Status Report #10
reports:

  Unpacking a space-based moving van and taking a second walk in space
is the order of business today for astronauts and cosmonauts orbiting
in the International Space Station and aboard Space Shuttle Endeavour.

  The Raffaello logistics module, now open for business following
yesterday's berthing to the side of the station's Unity module,
will be unloaded over the course of the next five days and then
reloaded with unneeded cargo from the station for return to Earth.

  While the Expedition Two crew of Commander Yury Usachev and Flight
Engineers Jim Voss and Susan Helms begin to transfer goods from
Raffaello, on the other side of the hatch aboard Endeavour, Scott
Parazynski and Chris Hadfield planned to conduct the second
Extravehicular Activity beginning about 8 a.m.

  The first order of business for the veteran spacewalkers will be to
connect power, computer and video cables to the Power and Data Grapple
Fixture on the side of the station's Destiny laboratory. An antenna
on Unity will be removed, as it is no longer needed. Cables on the
pallet that carried the new robot arm to the station will be
disconnected. Once those cables are removed, the Canadian-built
Canadarm2 will be receiving power and communicating with the
station's Robotics Work Station inside Destiny.

  Near the end of the planned 6- hour spacewalk, Helms will
command the station's new robotic arm to pick up the 3,000-pound
pallet that delivered it to space. She then will maneuver the pallet
through various positions to test the arm with a load. Helms will
finish today's tests by maneuvering the pallet over Endeavour's
payload bay where it will remain parked overnight, still attached to
the high-tech robotic arm.

  The day began for the astronauts and cosmonauts with the dolcit
tones of Louis Armstrong singing What A Wonderful World. The
song was played for Parazynski in honor of today's spacewalk.

  Included in the nearly two tons of equipment being off-loaded from
the Italian-built Raffaello are two new experiment racks that soon
will be filled with science experiments currently in Endeavour's
middeck, and other experiments that will be brought to the station on
future shuttle missions. Once the hatches are open late this afternoon
after the spacewalk, European Space Agency astronaut Umberto Guidoni
will take the lead in assisting the station crewmembers in the
unloading of Raffaello and the repacking of discarded items in the
module for return to Earth.

  Both spacecraft are in excellent shape orbiting the Earth every 92
minutes at an altitude of 237 statute miles. The next status report
will be issued this evening after the crew goes to sleep, or when
events warrant.

 On Tuesday, April 24, 2001, 6:30 p.m. CDT, STS-100 MCC Status Report #11
reports:

  Endeavour's two space walkers -- Canadian Chris Hadfield and
American Scott Parazynski-- worked as space-age electricians today,
completing connections that allowed the new International Space
Station robotic arm to operate from a new base on the outside of the
Destiny science lab.

  Expedition 2 Flight Engineers Jim Voss and Susan Helms steered
Canadarm2 as it lifted its first payload in space, a 3,000-pound
pallet that the 57-foot-long arm had been nestled in for launch in the
shuttle's cargo bay.

  Today's 7 hour, 40 minute spacewalk began at 7:34 a.m. Central
time, as Hadfield and Parazynski worked to complete all of the primary
goals of the mission, including the connection of the Power and Data
Grapple Fixture circuits for the new arm on Destiny, the removal of an
early communications antenna and the transfer of a spare Direct
Current Switching Unit from the shuttle's payload bay to an
equipment storage rack on the outside of Destiny.

  As the pair rewired power and data connections for Canadarm2, the
backup power circuit failed to respond to commanding from Helms, who
was operating from a workstation inside Destiny.  Hadfield and
Parazynski opened a panel to gain access to another connector at the
base of the arm and after disconnecting and reconnecting cables, were
able to complete the redundant power path to the arm to the cheers of
flight controllers in Houston.

  During the removal of the early communications antenna, an
electrical connector cover got away from Hadfield and nestled behind a
thermal cover in the docking port to which the airlock will be mated
in June. After two unsuccessful attempts to locate the errant piece of
metal  which required extensive coordination between the shuttle
and station flight control teams on the ground -- Hadfield was
instructed to stop searching and to move on to other work. The errant
component is not expected to have any impact on future
operations. With all of their work successfully completed, Hadfield
and Parazynski completed their space walk at 3:15 p.m., bringing the
total spacewalk time on STS-100 to 14 hours, 50 minutes. A potential
third spacewalk on Thursday likely will not be needed.

  Expedition Two Commander Yury Usachev and Station crewmates Voss and
Helms started their workday transferring supplies, equipment and
experiment racks from the Raffaello cargo module, which is berthed to
the Unity connecting node.

  After the spacewalk was completed, the two crews turned their
attention to reopening the hatches between the station and
shuttle. Commander Kent Rominger reported that Endeavour's crew had
returned to the ISS at 5:15 p.m. to set the stage for the resumption
of transfer activities on Wednesday. The two crews will begin their
sleep periods shortly after 6:30 p.m.

  Both spacecraft are in excellent shape orbiting the Earth every 92
minutes at an altitude of 237 statute miles. The next status report
will be issued Wednesday morning after crew wakeup, or sooner, if
events warrant.

  STS-100 Flight Day 7 Highlights:

 On Wedesday, April 25, 2001, 4:00 a.m. CDT, STS-100 MCC Status Report #12
reports:

  The Station's new robotic arm truly will extend the reach of
humans in space today when it hands the 3,000-pound pallet delivering
it to space to the shuttle's robotic arm for transport back to
Earth. The three-hour task is set to begin about 6 a.m.

  While robotic arm operations are underway by Expedition Two
crewmembers Susan Helms and Jim Voss aboard the station, and shuttle
crewmembers Chris Hadfield and Scott Parazynski, the remaining shuttle
and station astronauts and cosmonauts continue the task of unpacking
the Raffaello high-tech moving van. European Space Agency astronaut
Umberto Guidoni is overseeing the unloading of the Italian-built
logistics module.

  Today's wakeup call to the crew was Con te Partiro
(With You I Will Go), sung by Italian opera singer Andrea
Bocelli. It was played for Guidoni who is from Italy.

  Working at the Robotics Work Station in the Destiny Laboratory,
Helms and Voss will use the new Canadarm2 to maneuver the pallet
within reach of Endeavour's robotic arm under control of Hadfield
and Parazynski. In a reverse passing of the torch, the new arm will
pass the pallet to its older cousin officially beginning the station
arm's own career in space.

  Hadfield and Parazynksi completed connections on the station's
new robotic arm during the second of two planned spacewalks
yesterday. The 7 hour, 40 minute Extravehicular Activity included the
connection of power, data and television cables, which allow the robot
arm to operate from a base on the outside of the Destiny science
laboratory.

  At about 2:30 today, Endeavour's Commander Kent Rominger and
Pilot Jeff Ashby will boost the station's altitude another 2 
miles by firing thruster jets in a precise sequence for about one
hour. With one reboost maneuver completed several days ago, a third
and final identical firing of the reaction control system jets is
planned Thursday.

  Both spacecraft are in excellent shape orbiting the Earth every 92
minutes at an altitude of 243 statute miles. The next status report
will be issued late today, or if events warrant.

 On Wednesday, April 25, 2001, 8:30 p.m. CDT, STS-100 MCC Status Report #13
reports:

  Troubleshooting efforts designed to restore full capability to the
International Space Station's three redundant command and control
computers continue in Mission Control, even as the 10 astronauts and
cosmonauts on board the outpost worked together today to install new
experiments in the Destiny laboratory.

  Shortly after the ISS crew went to bed last night, the ISS flight
controllers reported a loss of Command and Control Computer number one
(C&C 1), one of three systems management computers on
board. Overnight, flight controllers inititiated a procedure to
re-string those functions through one of the two remaining backup
computers that route data for systems management. This morning when
Expedition Two Flight Engineer Susan Helms sent commands to transfer
data files from the mass storage device, which houses the files for
station systems management for the operation of the robotic work
stations, the command was rejected.

  After initial troubleshooting efforts failed to resolve the problem,
flight controllers once again worked a procedure to re-string data
management functions to the third computer, but the computer problem
continued and flight control teams continued to evaluate the situation
throughout the day.

  Following a power cycle of command and control computer 1, the first
of a series of diagnostic commands - this to turn on and off a light
on board the Destiny laboratory - was successfully transmitted from
the ground to the space station shortly before 7:30 p.m. Overnight the
space station flight control team will attempt to reset the computers
by commanding them from the "primary" to "standby" mode in an effort
to clear any software interaction that might be causing the
problems. If successful, this would allow the Expedition Crew and
ground controllers to again interface with the command and control
computers. The diagnostic troubleshooting will continue through the
night.

  The primary result of today's computer problem was a loss of
communication and data transfer between the Space Station Flight
Control Room and the station. Communication capability was routed
through Endeavour enabling the crew and flight controllers to talk to
one another.

  Despite the difficulties encountered with the computer system today,
all systems on board the spacecraft continued to function properly.

  Several of the activities planned for today, including the handoff
of a 3,000 pound pallete from the station's new robotic arm, back to
the shuttle's arm, were postponed until Thursday, pending resolution
of the computer issue. A reboost of the complex, using Endeavour's
small thrusters, also was delayed. The crew members instead turned
their attention to offloading experiment racks and equipment from the
Raffaello logistics module, and transferring the experiments and
hardware to the station.

  Once the computer difficulties are resolved, Helms and crew mate Jim
Voss will command the station's new Canadarm2 to maneuver the pallet
within reach of Endeavour's robotic arm under control of mission
specialists Chris Hadfield and Scott Parazynski.

  Shortly before 7 p.m. Central, Mission Control said goodnight to
both crews following a busy day on orbit. Expedition Two Commander
Yury Usachev, Voss and Helms are slated to wake up about 2:30
a.m. Thursday; the seven astronauts on board Endeavour will receive a
wake-up call from Mission Control about 10 minutes later.

  STS-100 Flight Day 8 Highlights:

 On Thursday, April 26, 2001, 5:30 a.m. CDT, STS-100 MCC Status Report #14
reports:

  Good news greeted space station flight controllers this morning
when, shortly after awakening, Expedition Two flight engineer Susan
Helms reported that the International Space Station computer systems
may be returning to normal. Working at a laptop computer aboard the
station that serves as the crew's primary interface with the station's
United States command and control computer system, Helms reported the
good news at about 3:45 a.m. Shortly afterward, Helms performed a
series of troubleshooting steps that restored the ground's ability to
monitor and send commands to the station's U.S. systems.

  Space station flight controllers then sent commands that have put
the station's systems in a better configuration in the event computer
problems recur today. They also are planning to send commands that
will transmit data to the ground from the station computers to allow
technicians to thoroughly analyze those computers' hardware and
software as part of the investigation that is under way to determine
the cause of the computer problems.

  Today's plan for the astronauts and cosmonauts aboard Endeavour and
the station will have them continue joint work this morning to reload
the Raffaello logistics module with unneeded station equipment and
supplies for return to Earth. The crews have almost completed
unloading the 4,000 pounds of equipment that Raffaello carried to the
station. While that reloading work takes place, flight controllers
will continue their analysis of the station computers.

  Given continued success with the computer troubleshooting, the crews
will resume work with the station's new Canadarm2 and the shuttle's
robotic arm after 8 a.m., handing off a 3,000-pound Spacelab Pallet
from the station arm to the shuttle arm to store the pallet back in
Endeavour's payload bay. Another reboost of the spacecraft's altitude
is planned later today as well, an hour-long jet firing by Endeavour
that will raise the complex's altitude by almost 4= miles.

  A practice run with the new station arm to rehearse moves the arm
must make during the next shuttle assembly mission to the station to
attach a new airlock will be conducted on Friday.

  The crew of Endeavour was awakened just after 2:40 a.m. by a Russian
folk song, "Behind the Fog." That song was played for Endeavour
crewmember Russian cosmonaut Yuri Lonchakov. The two spacecraft are
orbiting the Earth every 92 minutes at an altitude of 243 statute
miles. The next status report will be issued this evening at the end
of the crews' day or as events warrant.

 On Thursday, April 26, 2001, 10:30 a.m. CDT, STS-100 MCC Status Report #15
reports:

  Today, the astronauts and cosmonauts aboard Endeavour will continue
joint work to reload the Raffaello Logistics Module with unneeded
station equipment and supplies for return to Earth. The crews have
completed unloading the 4,000 pounds of equipment that Raffaello
carried to the station. While the reloading of Raffaello takes place,
flight controllers will continue their analysis of the station
computers. The station command and control computer brought on line
early this morning has continued to be fully functional and operate
normally throughout the day. Controllers are working to bring another
such computer online as a backup system later today. The recovery of
the one command and control computer during the night is believed to
have resulted from an automatic sequence aboard the station that
powered each of the three command and control computers on and off in
an attempt to bring them on line. The other two computers remained off
line, however.

  Given continued success with the computer recovery, the shuttle and
station crews will resume work with the station's new Canadarm2 and
the shuttle's robotic arm on Friday, handing off a 3,000-pound
Spacelab Pallet from the station arm to the shuttle arm to store the
pallet back in Endeavour's payload bay. A practice run with the new
station arm to rehearse moves the arm must make during the next
shuttle assembly mission to the station to attach a new airlock also
will be conducted on Friday.

  A second reboost of the station's altitude remains planned for later
today. It will be an hour-long jet firing by Endeavour that will raise
the complex's altitude by almost 4= miles. The two spacecraft are now
orbiting the Earth every 92 minutes at an altitude of 243 statute
miles.

 On Thursday, April 26, 2001, 8:30 p.m. CDT, STS-100 MCC Status Report #16
reports:

  As flight controllers continued to troubleshoot computer systems on
board the International Space Station (ISS), the ten crewmembers were
told late today they would spend some bonus time together, after
mission managers requested an additional two days of docked operations
to allow ground teams to recover the use of command computers in the
Destiny laboratory and to complete joint activities.

  Final confirmation of the two-day extension is pending Russian
concurrence of NASA's request for a one-day delay to their Soyuz
launch, currently scheduled for Saturday. That would allow Endeavour
to remain docked to the Station until at least Monday to help resolve
the computer problems which were first noticed Tuesday night. The
Soyuz vehicle was rolled out to its launch pad at the Baikonur
Cosmodrome in Kazakhstan at dawn today.

  With one of three command and control computers still up and running
on board the station, flight controllers worked through the day to
overcome what is believed to be a software problem with the other two
command computers and their processing systems. Ultimately a decision
was made to postpone the unberthing of the Raffaello logistics module
from the Unity module until Friday while ground controllers worked to
recover the computers. With other work on hold, the crewmembers
completed packing up Raffaello with unneeded gear and trash, which
will be brought back to Earth.

  If at least one additional command computer can be recovered
overnight, and engineers can reboot two fault protection computers in
the Unity module which also shut down earlier today, the Raffaello
module could be unberthed around midday Friday. Procedures to bring at
least one additional computer back on line for further operations are
expected to take about 10 hours.

  If Raffaello can be returned to Endeavour's cargo bay tomorrow, then
the crew will likely be given the green light to press ahead with the
handoff of a pallet from the newly installed Canadarm2 Station robot
arm to Endeavour's slightly smaller robot arm on Saturday, setting the
stage for undocking on Monday.

  To recover the two Unity computers, which offer a defense against
other computer malfunctions by automatically rebooting them,
controllers will have to perform a complex resynchronization procedure
early Friday shortly before the planned wakeup of the two crews.

  Endeavour has enough power and other consumables to remain in orbit
until Friday, if necessary. With a two-day mission extension, landing
would occur on Wednesday.

  The crews of Endeavour and the International Space Station are
scheduled to be awakened around 2:40 a.m. Central time
Friday. Meanwhile, all of Endeavour's systems continue to function
flawlessly as it orbits the Earth linked to the ISS.

  STS-100 Flight Day 9 Highlights:

 On Friday, April 27, 2001, 5:30 a.m. CDT, STS-100 MCC Status Report #17
reports:

 Flight controllers worked successfully overnight troubleshooting
computer problems on board the International Space Station and plan to
continue a recovery of full computer operations on the complex
today. The station and shuttle crews awoke this morning to find most
of the station's computers operating well and on line, although
efforts are continuing to bring up the orbiting outpost's backup
computers.

  The crew today will assist with bringing the remaining station
computers on line, including swapping a backup payload computer for
one of the station's three command and control computers. Of the three
station command and control computers, one is on line and fully
functional, providing full computer operations aboard the station. The
other two, which should serve as backups to the primary computer, are
off-line. Today's activities are planned to bring them on line as
well. The swap of one of those off-line command and control computers
with the backup payload computer will correct what is believed to be a
failed hard drive in that unit. The other off-line command and control
computer has been loaded with new software from the ground that should
correct its operating problems, although flight controllers have not
yet rebooted the unit.

  In addition to the station computer troubleshooting, the station and
shuttle crews today will continue to concentrate on the transfer of
supplies and equipment from the shuttle to the station. They also plan
to close the Raffaello logistics carrier's hatch and later detach that
module, using the shuttle's robotic arm to reberth it in Endeavour's
bay for a return to Earth. Almost 4,000 pounds of equipment and
supplies were unloaded from Raffaello onto the station. Yesterday, the
crew completed reloading it with items bound for Earth. The shuttle is
planned to boost the station's altitude by about 2.5 statute miles
today as well, the second such boost during the mission thus far.

  Managers have added an extra day to Endeavour's mission and are now
planning to have the shuttle remain docked to the station until Sunday
with a landing on Tuesday. A further extension of the mission also may
be considered. The crew of Endeavour was awakened this morning to the
song "Buckaroo," sung by Don Cain of Dubuque, Iowa, father of STS-100
Ascent and Entry Flight Director Leroy Cain. Except for the station
computer problems now being resolved, flight controllers have
identified no significant problems with any of the station or shuttle
systems. The next mission status report will be issued later today.

 On Friday, April 27, 2001, 7 p.m. CDT, STS-100 MCC Status Report #18
reports:

 The Italian Space Agency-provided Raffaello logistics module, loaded
with 1,600 pounds of material to be returned to Earth, was tucked
securely in Endeavour's payload bay at 3:58 p.m. Central time today as
the International Space Station and shuttle flew high over the Pacific
Ocean, north of Indonesia.

  Mission Specialist Scott Parazynski, at the controls of the
shuttle's robotic arm and assisted by European Space Agency Astronaut
Umberto Guidoni, grappled the 14,700 pound "moving van," undocking it
from the Destiny laboratory and carefully maneuvering it into position
before securing it in the payload bay. Over the course of the past
week, the astronauts and cosmonauts on board the station transferred
6,000 pounds of equipment from Raffaello to the station, and then
stowed unneeded equipment and hardware on board for return.

  The unberthing of Raffaello followed last night's work by ground
controllers to successfully synchronize timers on all the on-board
computers, including the one operational Control and Command (C&C)
computer in Destiny. With the one operational C&C computer, and Susan
Helms at the ready with a back-up laptop computer in Unity, the crew
was given a "go" to begin the undocking procedure about 2:20
p.m. today.

  Work to recover the command and control computers continued
throughout the day today, with good progress reported, and a reload of
software currently under way to restore C&C computer number three to
full performance. C&C computer number one was determined to have a
failed hard drive. That C& C computer will be replaced on orbit with a
a backup payload computer, called Payload Computer Two, so that the
failed C&C computer can be returned to Earth for inspection and
analysis. Overnight, flight controllers will reload software on C&C
number one in the hopes of bringing it back on line as well.

  The plan for the crew tomorrow, assuming a minimum of two C&C
computers are up and functioning, would see Helms and crew mate Jim
Voss operating the station's robotic arm to hand off its cradle to the
shuttle's robot arm, being commanded by Mission Specialists Scott
Parazynski and Chris Hadfield on board Endeavour. Most of the
activities planned for a "dress rehearsal" of the maneuvers the arm
will perform during the next station assembly mission to install an
airlock have been deleted from the timeline. Only the portions of the
rehearsal related to shuttle robotic arm camera views will be
performed.

  Earlier today, NASA and the Russian Aviation and Space Agency,
Rosaviakosmos, reached a decision on the launch of the Soyuz
replacement vehicle, for 2:37 a.m. central time
Saturday. Rosaviakosmos has agreed to delay the Soyuz docking to the
station if additional time is required to resolve command and control
problems aboard the station.

  Mission managers will assess the need for that additional docked day
of operations based on specific criteria, including a minimum of two
fully functioning command and control computers, securing the
Canadarm2 cradle pallet back in Endeavour's payload bay, successfully
reloading software in Command and Control computer Three, and
completing final transfer activities between the station and shuttle.

  With another busy day behind them, the two crews were bid goodnight
by Mission Control and will be awakened at 2:41 a.m. Saturday. Both
spacecraft are in good condition, orbiting the Earth every 92
minutes. The next mission status report will be issued following crew
wake-up Saturday, or earlier as events warrant.

  STS-100 Flight Day 10 Highlights:

 On Saturday, April 27, 2001, 6:30 a.m. CDT, STS-100 MCC Status Report #19
reports:

  The primary computer aboard the International Space Station
continued to work well through the night, but flight controllers
continued to encounter difficulties recovering the station's backup
computers.

  The station's two backup command and control computers remain off
line. Attempts overnight to reload software in one of the computers
were not successful. Analysts on the ground have uncovered an error in
the software load that they believe may have been the source of the
problem. Further efforts to reload software into the backup computers
are expected to resume later this morning.

  Even if backup computers are not yet on line, the crew may be given
a go today to use the station's robotic arm in an abbreviated maneuver
to hand a carrier pallet to Endeavour's arm so that it may be stowed
aboard the shuttle for a return to Earth. If so, the joint robotic
activities would begin no earlier than 8 a.m. to allow time for
managers to thoroughly evaluate the plan.

  Meanwhile, the crews are using the shuttle's robotic arm and cameras
and the station's cameras to calibrate the Space Vision System, a
precision alignment aid for operators of the robotic arm, and gather
information that will help prepare for the next shuttle mission to
visit the station. On that flight, planned for launch in June, the
Space Vision System will be a key aid for using the station arm to
attach a new airlock to the station. The crew also is continuing the
transfer of equipment from the shuttle to the station during the day,
and may work on some station maintenance tasks. A joint crew press
conference, during which the 10 astronauts and cosmonauts will field
questions from U.S., Canadian and European media, is planned at 1:41
p.m.  CDT.

 Shortly after Endeavour's crew awoke today, Mission Control reported
to them the successful launch of a replacement Soyuz spacecraft bound
for the station from the Baikonur Cosmodrome in Kazakstan. The Soyuz,
with a taxi crew of Commander Talgat A. Musabaev, Flight Engineer Yuri
M. Baturin and American businessman Dennis Tito, will replace the
Soyuz spacecraft now attached to the station, which is nearing the end
of its lifetime as a station emergency "lifeboat." The new Soyuz is
tentatively planned to dock with the station at 3:05 a.m. CDT Monday,
however the Soyuz docking plans will be delayed if a decision is made
to further extend Endeavour's stay at the station. 

 The shuttle crew was awakened today to the song "Dangerous," sung by
C'est Cheese, played for Canadian Astronaut Chris Hadfield at the
request of his wife. The station and shuttle are in an orbit of about
250 by 235 statute miles. 

 On Saturday, April 27, 2001, 8:30 p.m. CDT, STS-100 MCC Status Report #20
reports:

  Canadian "handshake in space" occurred at 4:02 p.m Central time
today, as the Canadian-built space station robotic arm - operated by
Expedition Two crew member Susan Helms - transferred its launch cradle
over to Endeavour's robotic arm, with Canadian Space Agency astronaut
Chris Hadfield at the controls. The exchange of the pallet from
station arm to shuttle arm marked the first ever robotic-to-robotic
transfer in space.

  The successful exchange of the pallet was the last remaining major
objective of the mission to be accomplished and could pave the way for
Endeavour to undock from the station Sunday morning, if computers on
board can be placed in a stable configuration overnight. Mission
managers had established three specific criteria to be met prior to
Endeavour's undocking. The criteria were to reberth the cradle pallet
in the shuttle's payload bay, complete final transfer activities and
place the station's command and control (C&C) computers in a stable
configuration.  With the pallet securely in Endeavour's payload bay
and all final transfer items in place, the one remaining item is to
ensure the computer system is in a stable configuration prior to
Endeavour's departure. Overnight, flight controllers will uplink a
series of commands designed to restore the two computers to full
capability. C&C three is in an acceptable condition, although it is
known to have a bad hard drive.  Helms and crew mate Jim Voss will
perform repair work on that computer at a later date.

  A final decision whether to undock Endeavour - and delay the docking
of the Soyuz replacement vehicle - is expected late tonight or early
Sunday morning.  After spending much of this morning refining
procedures to minimize inputs to the station's primary command and
control computer, which developed problems accessing its hard drive,
Space Station Flight Director Mark Ferring gave the Expedition Two
crew a "go" to begin with arm operations at 1:27 p.m. With Helms
working at the robotic work station, first motion of the station arm
occurred at 3:01 p.m. Through a series of carefully choreographed
commands, the station arm was maneuvered into its handoff
position. Hadfield then slowly moved Endeavour's 50-foot long robot
arm into position to latch onto the cradle, which was securely
attached to the station arm at 3:43 p.m. At 4:02 p.m., as the two
spacecraft flew over British Columbia, the pallet changed hands.

  Both arms then began backing away - with the station arm now under
command of Voss, according to plan. Hadfield then stowed the pallet in
Endeavour's payload bay at 4:51 p.m.

  Earlier in the day, Voss informed flight controllers that Endeavour
crew members were helping with maintenance activities on the station's
treadmill, called TVIS, installing new hardware to allow the
Expedition crew to once again use it for exercise. The treadmill's
walking surface had degraded and the crew had been told not to use it
until repairs were made. Voss reports repairs are now about 50 per
cent complete.

  After enjoying a meal together, both crews were scheduled to go to
sleep shortly after 7 p.m. Both crews will enjoy an extra hour of
sleep, waking up just before 4 a.m.  Due to a compressed schedule
tomorrow, the in-flight crew news conference, originally scheduled for
6:15 a.m. Sunday, has been canceled.

  If a decision is made to undock tomorrow, the astronauts and
cosmonauts will exchange final farewells about 9:30 a.m. and then
begin closing the hatches between the two spacecraft. Undocking would
occur at 12:34 p.m. central. Pilot Jeff Ashby would then slowly back
Endeavour away to a distance of approximately 450 feet, where he will
begin a three-quarter circle flyaround of the station before
commanding a final separation burn signaling Endeavour's final
departure from the station. With an undocking Sunday, the mission is
scheduled to conclude with a landing at the Kennedy Space Center at

 On Sunday, April 28, 2001, 5:00 a.m. CDT, STS-100 MCC Status Report #21
reports:

  Endeavour's crew and the crew of the International Space Station
will say farewell today, ending an eight-day visit by the shuttle that
saw delivery a new robotic arm and more than six tons of supplies and
equipment to the complex, including two scientific experiment racks
for the U.S. laboratory Destiny.

  The crews are plan to close the hatches between the two spacecraft
at 9:41 a.m..  Endeavour is scheduled to undock from the station at
12:34 p.m. With Pilot Jeff Ashby at the controls, the shuttle will
back away to distance of about 450 feet to perform a three-quarters
circle of the station which will include a special maneuver to allow
filming by a payload bay-mounted IMAX camera. At 1:32 p.m., Ashby will
fire Endeavour's jets to separate the vicinity of the station and put
Endeavour on course for a 7:59 a.m. CDT Tuesday landing at Kennedy
Space Center in Florida.

  Aboard the station, all three command and control computers - one
primary and two backups -- are on line and operating well. One, the
primary computer, has full capabilities. Of the two backups, one is
functioning but has a failed hard drive. The third is working but
flight controllers are still bringing up its hard drive.

 After Endeavour undocks today, the station crew will have the
afternoon off duty. A Russian Aviation and Space Agency Soyuz
spacecraft with a crew of three - Commander Talgat Musabaev, Flight
Engineer Yuri Baturin and American businessman Dennis Tito -- is
planned to dock with the station at 2:52 a.m. Monday.  The Soyuz,
which will replace the Soyuz now docked to the station as a space
"lifeboat" for the complex, is trailing the complex by about 6,000
statute miles.

  Endeavour's crew was awakened this morning by the song "Miles from
Nowhere," performed by Cat Stevens and played for Ashby in
anticipation of today's undocking. A crew news conference for
Endeavour's crew is tentatively planned for Monday morning.  


 On Sunday, April 28, 2001, 4:00 p.m. CDT, STS-100 MCC Status Report #22
reports:

  With a gentle push from springs in the docking module, Endeavour
backed slowly away from the International Space Station at 12:34
p.m. Central time today, as the two spacecraft soared 240 miles over
the South Pacific Ocean, east of Australia.

  As Pilot Jeff Ashby slowly backed Endeavour away, Commander Kent
Rominger and Expedition Two flight engineer Susan Helms exchanged
final wishes for Endeavour's planned return to Earth, and a continued
safe journey for the station crew. Once Endeavour was at a distance of
450 feet from the station, Ashby initiated a three-quarter circle
flyaround of the station as Mission Specialist Yuri Lonchakov
activated a large-format IMAX camera in Endeavour's payload bay to
photograph the station.

  At 1:28 p.m., with the flyaround complete, Ashby fired a separation
burn, initiating Endeavour's final departure from the orbiting
complex, now equipped with a new Canadian-built robotic arm and
communications antenna, installed by Mission Specialists Scott
Parazynski and Chris Hadfield during two space walks. During eight
days of joint operations, the two crews also transferred more than
three tons of supplies, equipment and scientific experiments to the
station.

  On board the station, the Expedition Two crew - Commander Yury
Usachev and Flight Engineers Jim Voss and Helms - will enjoy some time
off this afternoon following a busy week on orbit. Early Monday
morning, they will support the docking of a replacement Soyuz
spacecraft that will serve as the station's "lifeboat." The Soyuz and
its crew of three - Commander Talgat Musabayev, Flight Engineer Yuri
Baturin and American businessman Dennis Tito -- is scheduled to dock
at 2:52 a.m. Monday.  Endeavour's crew will go to sleep shortly after
4:30 p.m. today, awakening at 1:41 a.m. Monday to begin what should be
their final full day on orbit. Endeavour is scheduled to return to the
Kennedy Space Center, weather permitting, at 8:03 a.m.  Tuesday. The
primary activity for the crew on Monday will center on Endeavour's
return to Earth, with Rominger, Ashby and Flight Engineer John
Phillips verifying the performance of Endeavour's flight control
surfaces and steering jets. Hadfield, Parazynski, Lonchakov and
Umberto Guidoni will begin stowing away much of the equipment the crew
has used over the past 11 days on orbit. All seven crew members are
scheduled to participate in a press conference, talking with media in
the U.S., Canada and Italy, at 10:01 a.m. Monday.

Payload:
  Space Station Assembly Flight ISS-7A (ISS-Airlock, HPGA)

Mission Objectives:
  The primary purpose of the flight is to deliver and install the ISS
Airlock.  The Joint Airlock is a pressurized flight element consisting
of two cylindrical chambers attached end-to-end by a connecting
bulkhead and hatch. Once installed and activated, the ISS airlock becomes
the primary path for International Space Station space walk entry and
departure for U.S. spacesuits, which are known as Extravehicular
Mobility Units, or EMUs. In addition, the Joint Airlock is designed to
support the Russian Orlan spacesuit for EVA activity.

  The Joint Airlock is 20ft long, 13ft in diameter and weighs 6.5
tons.  It was built at the Marshall Space Flight Center (MSFC) by the
Space Station Prime Contractor Boeing.  The ISS-airlock has two main
components: a crew airlock and an equipment airlock for storing EVA
gear and EVA preflight preps.  STS-104 also carries a spacelab pallet
with four High Pressure Gas Assembly containers that will be attached
to the exterior of the airlock.

Launch:
  July 12, 2001 5:04 a.m. EDT.  10 min window.  Tanking
operations were completed at 10:35 p.m. EDT.  At 4:55 a.m., the
countdown clock came out of the T-minus 9 minute hold and entered
the final count.  The Crew Access Arm was retracted at 4:56 a.m.
EDT.  Launch occured at the opening of the launch window.

 On Sunday evening, July 8, the flight crew for mission STS-104
arrived to begin final preparation for their upcoming launch. Space
Shuttle Atlantis.  Over the weekend, workers completed orbiter aft
compartment closeouts. Technicians also successfully replaced and
retested an orbiter mass memory unit and a TV monitor on the aft
flight deck launch window.  (Reference KSC Shuttle Status 7/09/2001)

 On Wednesday, June 20, 2001, following a go ahead from Shuttle
management, KSC workers began rolling Space Shuttle Atlantis out of
the VAB at about 2:30 a.m. today. When weather officials noted the
threat of lightning in the vicinity of the Launch Complex 39 area,
managers returned Atlantis to the VAB as a safety precaution. Atlantis
has been rescheduled for rollout to Launch Pad 39B at about 12:30
a.m. Thursday, June 21.  (Reference KSC Shuttle Status 6/20/2001)

  On Tuesday, June 19, 2001, Space Shuttle and International Space
Station managers agreed to proceed with plans to launch Space Shuttle
Atlantis no earlier than July 12. The official launch date will be
announced after the Flight Readiness Review scheduled for June 28. The
Terminal Countdown Demonstration Test is scheduled for June 28-29 at
KSC.  (Reference KSC Shuttle Status 6/20/2001)

 On Thursday, May 31, 2001, NASA managers announced that Space Shuttle
Atlantis will not launch before early July. The additional time will
enable the International Space Station Program time to evaluate a
problem with the Station's new robot arm. Shuttle and Station managers
will reconvene in mid-June to assess a new launch date. The Flight
Readiness Review has been postponed with a new date to be announced.
Orbiter Atlantis rolled over to the Vehicle Assembly Building (VAB)
last night, and workers are preparing to mate the orbiter to the
external tank in VAB high bay 1. Once fully stacked, the Space Shuttle
will remain in the VAB until a new rollout date is selected.  
(Reference KSC Shuttle Status 5/31/2001)

  Managers announced a target launch date of no earlier than June 8
for Atlantis' next flight on mission STS-104. This shift accommodates
an on orbit sun angle condition between May 18 and June 7. This
so-called beta angel cut-out is an undesirable thermal condition for
Shuttle/ISS docking operations.  Previous launch date was no earlier
than February 8, 2001.  (Reference KSC Shuttle Status 1/25/2001)

Payload:
  ISS 7A.1 MPLM (Leonardo), MISSE, GAS (G-708), Hitchhiker (Simplesat, MSC, SEM-10)

Mission Objectives:
 Space Station Flight 7A.1

  The main purpose of STS-105 is the rotation of the International
Space Station crew and the delivery of supplies utilizing the
Italian-built Multipurpose Logistics Module (MPLM) Leonardo on its
second flight ( STS-102 , STS-105 ).  Astronauts will also perform two
spacewalks and conduct scientific experiments.  The MPLM on this
mission contains additional scientific racks, equipment and
supplies. It is 6.4 meters long (21ft) and 4.6 meters (15ft) in
diameter) and weighs over 9,000 lbs. An identical module named
Raffaello has flown once (STS-100).

  Aboard Leonardo are six Resupply Stowage Racks, four Resupply
Stowage Platforms, and two new scientific experiment racks for the
station's U.S. laboratory Destiny. The two new science racks (EXPRESS
Racks 4 and 5) will add science capability to the station. EXPRESS
stands for Expedite the Processing of Experiments to the Space
Station. EXPRESS Rack 4 weighs 1,175 pounds and EXPRESS Rack 5 weighs
1,200 pounds. The empty weight of each EXPRESS rack is about 785
pounds.  EXPRESS Racks 1 and 2A were delivered aboard the Raffaello
cargo module during STS-100/6A in April 2001. EXPRESS Rack 3 is
scheduled to be brought to the station during STS-111/UF-2 in 2002.

 The Resuppy Stowage Racks and Resupply Stowage Platforms are filled
with Cargo Transfer Bags that contain equipment and supplies for the
station. The six Resuppply Stowage Racks contain almost 3,200 pounds
of cargo and the four Resupply Stowage Platforms contain about 1,200
pounds of cargo, not including the weight of the Cargo Transfer Bags,
the foam packing around the cargo or the straps and fences that hold
the bags in place.  The total weight of cargo, racks and packing
material aboard Leonardo is just over 11,000 pounds. Total cargo
weight is about 6,775 pounds.


  Another payload onboard is the Materials International Space Station
Experiments (MISSE).  This project is a NASA/Langley Research
Center-managed cooperative endeavor to fly materials and other types
of space exposure experiments on the space station. The objective is
to develop early, low-cost, non-intrusive opportunities to conduct
critical space exposure tests of space materials and components
planned for use on future spacecraft.  Johnson Space Center, Marshall
Space Flight Center, Glenn Research Center, the Materials Laboratory
at the Air Force Research Laboratory and Boeing Phantom Works are
participants with Langley in the project.  The MISSE experiments will
be the first externally mounted experiments conducted on the ISS. The
experiments are in four Passive Experiment Containers (PECs) that were
initially developed and used for an experiment on Mir in 1996 during
the Shuttle-Mir Program. The PECs were transported to Mir on
STS-76. After an 18-month exposure in space, they were retrieved on
STS-86.  PECs are suitcase-like containers for transporting
experiments via the space shuttle to and from an orbiting
spacecraft. Once on orbit and clamped to the host spacecraft, the PECs
are opened and serve as racks to expose experiments to the space
environment.

  Other payloads onboard are part of the Goddard Space Flight Center's
Wallops Flight Facility Shuttle Small Payloads Project. The SSPP
system utilizes payload carrier systems such as the Hitchhiker,
Getaway Specials and Space Experiment Modules to provide a low cost
scientific research enviromnent.  SSPP payloads on STS-105 include the
Hitchhiker payload Simplesat, The Cell Growth in Microgravity GAS
Canister (G-708), the Microgravity Smoldering Combustion experimet
(MSC), and the Hitchiker Experiment Advancing Technology Space
Experiment Module-10 payload).

  On Friday, the loading of cryogenic propellants began at 8:10 a.m. EDT
and was completed at 11:07 a.m. EDT.  The flight crew received a
weather briefing at 12:45 a.m. EDT, ate breakfast and then departed
for the launch pad at 1:25 p.m. EDT.  Orbiter ingress began at 1:55 p.m. EDT
and the hatch was closed at 3:10p.m. EDT.   The access arm was retracted
at 5:03 p.m. EDT.  Launch occured at 5:10 p.m. EDT at the opening of
the launch window.

  On Thursday beginning at 8:20 a.m. and completing at 11:21 a.m. EDT,
the external tank was loaded with its complement of 500,000 gallons of
liquid cryogenic propellants. The crew departed for the pad at 1:47
p.m. and closeout was at 3:32 p.m. EDT.  The countdown progressed to
the T-minus 9 minute mark where the launch was scrubbed due to
weather.

  On Tuesday, August 7, 2001, launch countdown activities continue on
schedule. Operations to load the Power Reactant and Storage
Distribution (PRSD) system tanks with cryogenic reactants began late
this afternoon. Loading operations are scheduled to be completed by
early tomorrow morning, at which time the orbiter mid-body umbilical
unit will be demated.  Later tomorrow, the communications system on
the Shuttle will be activated and tested and the rotating service
structure will be moved to the launch position at about 9:30 p.m.
(Reference KSC  Shuttle Status 8/07/01) 

  On Monday, August 6, 2001, after a thorough engineering evaluation,
Shuttle managers determined that the hydraulic power unit on
  Space Shuttle Discovery's left-hand solid rocket booster is ready
for flight with no additional work required.  The launch countdown
began on time at 5 p.m. in firing room No. 3. and preparation at Pad
39A continues on schedule toward the Aug. 9, STS-105 launch
date. Discovery's aft compartment has been closed out for flight and
Shuttle ordnance installation is complete. Payload interface
verification testing is also complete.  The STS-105 crew and
Expedition 3 crew arrived at KSC Sunday at about 1:15 p.m. to begin
final preparation for flight.  (Reference KSC Shuttle Status 8/06/01)

  On Wednesday, August 1, 2001, during the Flight Readiness Review
NASA managers confirmed Aug. 9 as the official launch date for
STS-105. At Launch Pad 39A, workers completed replacement of
Discovery's master events controller No. 2 and retests are nearing
completion. (Reference KSC Shuttle Status 8/02/01)

  On Wednesday, June 20, 2001, with the orbiter, external tank and
solid rocket boosters fully stacked in VAB high bay 3, Space Shuttle
Discovery underwent Shuttle Interface Testing earlier this week. Final
preparations for rollout to Launch Pad 39A are in work. Discovery
could roll to the pad as early as June 26.
 (Reference KSC Shuttle Status 6/20/2001)

  NASA managers announced that Space Shuttle Discovery's launch
will occur no earlier than early August. The delay accommodates the
ongoing robot arm evaluation and allows the flight crew additional
time to train for potential arm repair efforts during the upcoming
mission.  (Reference KSC Shuttle Status 5/31/2001)

  STS-105 Flight Day 1 Highlights:

 On Friday, August 10, 2001, 4:30 p.m. CDT, STS-105 MCC Status Report #1
reports:

  After a one-day delay because of weather, Space Shuttle Discovery
blasted off this afternoon, carrying a crew of four and three new
residents to the International Space Station.

  As the station sailed over the Pacific Ocean southwest of the border
between Mexico and Guatemala, Discovery rocketed away from Launch Pad
39-A at the Kennedy Space Center at 4:10 p.m. Central time en route to
a rendezvous and docking Sunday afternoon.

  Aboard Discovery were Commander Scott Horowitz, Pilot Rick Sturckow
and Mission Specialists Pat Forrester and Dan Barry along with
Expedition Three Commander Frank Culbertson, Pilot Vladimir Dezhurov
and Flight Engineer Mikhail Tyurin. They will replace the Expedition
Two crew, Commander Yury Usachev and Flight Engineers Jim Voss and
Susan Helms, who were wrapping up their 155th day in space at the time
of Discovery's launch.

  Less than nine minutes after beginning its journey, Discovery
settled into its preliminary orbit as the crew prepared to open the
ship's payload bay doors prior to receiving the green light to
begin orbital operations. This is the fifth shuttle mission of the
year.

  Discovery's crew will spend the next few hours unpacking equipment,
setting up computers and conducting the first in a series of engine
firings to refine the shuttle's orbit as it heads for the
station. The crew will begin an eight-hour sleep period shortly after
11 p.m. and will be awakened at 7:15 a.m. Saturday for its first full
day in orbit. That day will be devoted to preparations for Sunday's
rendezvous and docking and eight days of joint operations with the
Expedition Two crew, highlighted by the official transfer of command
of the station from Usachev to Culbertson .

  Aboard the station, Usachev, Voss and Helms have spent most of the
past couple of weeks packing gear for the trip home aboard Discovery,
and tidying up for the arrival of visitors about 1:30 p.m. Sunday.

  Discovery is in an orbit inclined 51.6 degrees to either side of the
Equator with all of its systems operating normally.


  STS-105 Flight Day 2 Highlights:

 On Saturday, August 11, 2001, 8:00 a.m. CDT, STS-105 MCC Status Report #2
reports:

  The seven crewmembers aboard Discovery were awakened shortly after 7
a.m. Saturday for their first full day in space, a day of pursuit and
preparation for a Sunday rendezvous and docking with the
International Space Station (ISS).

  Discovery's astronauts and cosmonauts, Commander Scott Horowitz,
Pilot Rick Sturckow and Mission Specialists Pat Forrester and Dan
Barry, and Expedition Three Commander Frank Culbertson, Pilot
Vladimir Dezhurov and Flight Engineer Mikhail Tyurin, were awakened
to &quot;Back in the Saddle Again&quot; by Gene Autry. It was played
for Culbertson, making his third flight into space, eight years
after he last flew.

  At the time the crew was awakened, some 8000 statute miles separated
Discovery from the ISS. A second firing of Discovery's orbital
maneuvering systems engines is scheduled for early in the crew's day
today to further adjust its orbit in preparation for rendezvous and
docking with the station. Also scheduled today are the checkout of
spacesuits to be worn by Barry and Forrester during two spacewalks
next week, the preparation of rendezvous and navigation tools and a
test of the shuttle's robotic arm, all routine work on the day before
docking.  Crewmembers also will perform a camera survey of Discovery's
cargo bay with arm-mounted cameras.

  Discovery is scheduled to linkup to the ISS tomorrow at 1:37
p.m. Central time as the two spacecraft fly over the Indian Ocean
northwest of Australia, just south of the Indonesian island of Jawa.

The major objective of the STS-105 mission of Discovery is the swapout of the new resident Station crew, led by Culbertson, with the Expedition Two crew, Commander Yury Usachev and Flight Engineers Jim Voss and Susan Helms, who have been aboard the Station more than five months.  They are to return to Earth aboard Discovery on August 22.

  Discovery also is bringing equipment, supplies and scientific
experiments to the Station.  Almost 7,000 pounds of that cargo is in
Leonardo, the Italian-built Multipurpose Logistics Module in
Discovery's cargo bay. Once that is transferred to the station,
Leonardo will be packed with other equipment, unused items and trash
for return to Earth.

  During their eight days docked to the station, Discovery Mission
Specialists Barry and Forrester will perform two spacewalks.  On the
first, next Thursday, they will install an device called an Early
Ammonia Servicer on the Station.  It contains spare ammonia that could
be used to cool Station systems should it be needed.  During the
second spacewalk, two days later, they will install heater cables for
the station's large S0 truss segment, which will be delivered on a
future mission, as well as handrails.

  Discovery is orbiting the Earth in excellent shape with no issues
being worked by the flight control team.

  The next mission status report will be issued Saturday evening prior
to the start of the crew's sleep period, or earlier, as events
warrant.

 On Saturday, August 11, 2001, 7:00 p.m. CDT, STS-105 MCC Status Report #3
reports:

  The seven crewmembers aboard Discovery, including the future residents
of the International Space Station (ISS), spent their first full day
in orbit today preparing for their arrival tomorrow at the orbital
outpost.

  Commander Scott Horowitz, Pilot Rick Sturckow and Mission Specialists
Pat Forrester and Dan Barry, along with Expedition Three Commander
Frank Culbertson, Pilot Vladimir Dezhurov and Flight Engineer Mikhail
Tyurin, checked out Shuttle systems, navigational tools and docking
hardware in advance of Discovery's planned linkup to the ISS.

  The docking is scheduled to occur Sunday at 1:38 p.m. Central time
over the Indian Ocean northwest of Australia, just south of the
Indonesian island of Jawa.

  Forrester and Horowitz powered up, unfurled and checked out
Discovery's 50-foot long robotic arm, which will be used by Forrester
to move the Leonardo cargo module from Discovery's payload bay to the
ISS for the transfer of food and supplies, and by Horowitz to
transport Barry and Forrester around the Station during their two
spacewalks next week.

  In addition, Barry and Forrester tested the devices they will use
tomorrow to measure Discovery's distance from the ISS and its rate of
closure on the complex during the terminal phase of the Shuttle's
approach to the Station.
 
  Discovery's docking mechanism was also checked out and its outer
docking ring extended to insure it is ready for tomorrow's capture of
the ISS docking port on the forward end of the Station's Destiny
laboratory module.

  Next week, Barry and Forrester will test the spacesuits they will wear
during their two excursions outside Discovery to attach a spare
cooling reservoir to the ISS and to hook up heating cables for a large
truss structure that will be mounted to the Station next year.

  The crew enjoyed a few hours of spare time this afternoon to relax as
they wound down for the start of an eight-hour sleep period just after
9 p.m. Central time tonight.

  Aboard the ISS, Expedition Two Commander Yury Usachev and Flight
Engineers Jim Voss and Susan Helms spent the day packing up personal
items and preparing Station systems for tomorrow's arrival of their
replacements, Culbertson, Pilot Vladimir Dezhurov and Flight
Engineer Mikhail Tyurin. This was the 156th day in space for the
current occupants of the ISS.

  The exchange of crew members on the Station will occur on Monday,
although formal command of the Station will not be transferred from
Usachev to Culbertson until a few hours before Discovery's undocking
on August 20.

  Almost 7,000 pounds of food, supplies and personal items for the
Expedition Three crew are housed in Leonardo, the Italian-built
Multi-Purpose Logistics Module (MPLM). Once the module is transferred
to the Station and unpacked, it will be filled with equipment no
longer needed on the ISS, including Expedition Two crew clothing and
trash for return to Earth.

  Discovery is orbiting the Earth in excellent shape with no issues
being worked by the flight control team.


  STS-105 Flight Day 3 Highlights:

 On Sunday, August 12, 2001, 6:00 a.m. CDT, STS-105 MCC Status Report #4
reports:

  The crew of Discovery, trailing the International Space Station by
less than 2,000 statute miles, was awakened at 5:10 a.m. Central time
to the sounds of &quot;The White Eagle,&quot; a traditional Russian
folk song played for Expedition Three Pilot Vladimir Dezhurov.
Dezhurov and his crewmates, Expedition Three Commander Frank
Culbertson and Flight Engineer Mikhail Tyurin are just hours from
reaching their new home aboard the International Space Station (ISS).

  Discovery Commander Scott Horowitz, Pilot Rick Sturckow and Mission
Specialists Pat Forrester and Dan Barry, along with the Expedition
Three crew, will begin rendezvous operations a little before 9
a.m. today. The shuttle will begin a final approach to the station
from a point about 9 miles behind the outpost with the last major
rendezvous maneuver scheduled at around 11:15 a.m.

  With Discovery about 600 feet directly below the station, Horowitz
will fly the shuttle in a quarter circle to a point in front of the
complex.  From there he will very slowly and precisely maneuver
Discovery toward the station, pausing about 30 feet from the ISS to
precisely align the docking mechanisms of the two craft.

  Docking is expected to occur at 1:38 p.m. over the Indian Ocean just
south of the Indonesian island of Jawa. The hatches separating the two
spacecraft are to be opened around 3:30 p.m. allowing the current
station residents, Expedition Two Commander Yury Usachev and Flight
Engineers Jim Voss and Susan Helms to greet their replacements and the
Discovery astronauts who will bring them home after more than five
months in space.

  ISS flight controllers are expected to ask the Expedition Two crew on
Wednesday to try to reboot one of three command and control computers
which experienced a hard drive problem last week and which has been
put in standby mode with no impact to station operations. If the
reboot does not recover the use of the hard drive, the crew may be
asked to replace a component in the computer with a spare being
brought to the station on Discovery. Two other command and control
computers, a prime and a backup, are working perfectly in support of
U.S. segment systems.

  Discovery is orbiting the Earth every 90 minutes in good shape in
pursuit of the International Space Station.

reports:

  New residents arrived at the International Space Station (ISS) today
following a flawless docking of Discovery to the orbital outpost to
relieve a trio of space travelers who have lived and worked on the
complex since March.

  Discovery Commander Scott Horowitz, with the assistance of Pilot Rick
Sturckow and Mission Specialists Pat Forrester and Dan Barry,
carefully guided the Shuttle to a linkup with the ISS at 1:42
p.m. Central time as the two craft sailed 240 miles above northwestern
Australia. On board Discovery were the new Station Commander Frank
Culbertson, and his Expedition Three crewmates, Pilot Vladimir
Dezhurov and Flight Engineer Mikhail Tyurin.

  Expedition Two Commander Yury Usachev and Flight Engineers Jim Voss
and Susan Helms looked on from the station's Destiny laboratory as
Discovery arrived this afternoon, then worked in concert with their
Shuttle counterparts to ensure a tight seal and a firm mate between
the two vehicles.

  At 3:41 p.m., hatches finally swung open between Discovery and the
ISS, and the two crews greeted one another.  First aboard the station
was Culbertson to survey his home for the next four months.  Within
minutes, all ten astronauts and cosmonauts had shared greetings before
settling in for a station safety briefing conducted by Usachev.

  Monday the crews will attach the Leonardo cargo carrier to the station
at about 9:30 a.m. and begin unloading its supplies.

  Just prior to this operation, the two station crews will
systematically begin the process of handing over command from
Expedition Two to Expedition Three.  The plan is for Culbertson and
Helms to remove her form-fitting seat liner from the Soyuz spacecraft
and replace it with Culbertson's at about 7 a.m.  Two hours later at
about 9 a.m., Dezhurov and Usachev will do the same followed at 12:30
p.m. by the seat liner swap of Tyurin and Voss.  The Soyuz is used as
a return vehicle in the event of a problem on the station.

  Crew sleep is scheduled for about 8 tonight with a musical wakeup
call from Mission Control at 5:10 a.m. Monday.  The station and
shuttle complex is orbiting the Earth every 92 minutes in good shape.

  The crewmembers aboard the Discovery / International Space Station
complex were awakened shortly before 4:30 a.m. Central time today to
the sounds of the overture from &quot;The Barber of Seville&quot; by
Rossini, a tribute to Expedition Three Flight Engineer Mikhail Tyurin,
who along with Commander Frank Culbertson and Pilot Vladimir Dezhurov,
will move over to the ISS today to take up residency.

  Once they swap out their custom-made Soyuz capsule seat liners with
those belonging to Expedition Two Commander Yury Usachev and Flight
Engineers Jim Voss and Susan Helms, Culbertson, Dezhurov and Tyurin
will become the third trio of residents to inhabit the complex, while
Usachev, Voss and Helms become members of Discovery's crew.

  The Soyuz serves as a crew return vehicle in the unlikely event it
should become necessary to leave the station.

  Official handover of command of the ISS from Usachev to Culbertson
will take place on August 20, shortly before Discovery undocks from
the Station.

  After the crew transfer is complete, the oncoming ISS residents will
begin a comprehensive handover with their departing counterparts,
receiving briefings on Station systems, the current configuration of
hardware and computers and procedures they will employ during their
first days on board the outpost.

  Mission Specialist Pat Forrester will use Discovery's robot arm to
move the Italian-built Leonardo cargo module from the shuttle's
payload bay to the nadir docking port of the Station's Unity module so
it can be unloaded of more than three tons of supplies and equipment
for the newly arrived Expedition Three crew. Leonardo also contains
racks of scientific experiments which will greatly enhance the
scientific research on board the ISS over the next few
months. Leonardo will be installed on the Station late this morning.

  Other equipment will be transferred throughout the day from
Discovery's middeck lockers to the ISS as the crews work in concert to
set the stage for the Expedition Three mission.

  The joined spacecraft are orbiting at an average altitude of about
244 statute miles, completing an orbit of the Earth every 90 minutes.
Both craft are in good condition.

International Space Station scheduled for 9:52 a.m. CDT Monday.

  The ten crewmembers aboard Discovery and the station are spending
their final day and night together prior to the farewell ceremony and
hatch closing scheduled for about 7 a.m. CDT tomorrow. That follows
the wakeup call from Mission Control set for 4:40 a.m.


  Leonardo brought almost 7,000 pounds of material to the station,
including equipment, supplies and two scientific racks for the new
Expedition Three crew of Commander Frank Culbertson, Pilot Vladimir
Dezhurov and Flight Engineer Mikhail Tyurin.  Leonardo -- one of three
pressurized cargo carriers provided by the Italian Space Agency --
completes its second visit to the station.


  Astronaut Pat Forrester carefully removed the high-tech moving van
from the station and placed it back in Discovery's payload bay at 2:15
p.m. CDT. He was backed up throughout the operation by Discovery
Commander Scott Horowitz, who operated the arm during the spacewalks
by Forrester and Dan Barry to outfit the station with spare equipment
and scientific gear.

  Once Discovery departs, Pilot Rick Sturckow will perform a strategic
fly around of the station at a distance of about 400 feet before
firing thrusters shortly after 11 a.m. to depart the vicinity of the
complex. Wednesday afternoon, Discovery is set to return to the
Kennedy Space Center with the Expedition Two crew of Yury Usachev, Jim
Voss and Susan Helms. The three departed the Florida spaceport March 8
and will return after 167 days in space.

  Meanwhile, Russian space officials are set to launch the fifth
Progress resupply craft to the International Space Station Tuesday at
4:24 a.m. Central time followed by an automatic docking early
Thursday. The Progress will carry supplies, food and equipment for the
new Expedition Three crew. Its predecessor will be undocked Wednesday
and commanded to burn up harmlessly in Earth's atmosphere.


  Discovery and the ISS are orbiting the Earth every 90 minutes at an
altitude of 246 statute miles with all systems functioning
normally.

  STS-105 Flight Day 11 Highlights:

 On Monday, August 20, 2001, 5:00 a.m. CDT, STS-105 MCC Status Report #20
reports:

  Crewmembers aboard Discovery and the International Space Station are
spending their final hours together on a day that will see them bid
farewell to one another, close hatches between the spacecraft, undock
and separate to enable the new resident Expedition Three crew to begin
a stay of about four months aboard the station.

  The final farewells and hatch closing are scheduled for just before
7 a.m. Central time.  Discovery's crewmembers, Commander Scott
Horowitz, Pilot Rick Sturckow, and Mission Specialists Pat Forrester
and Dan Barry, assisted by the returning Expedition Two crew,
Commander Yury Usachev and Astronauts Jim Voss and Susan Helms, will
undock Discovery at 9:52 a.m. as the two craft sail over the south
Pacific due west of the southern coast of Chile.

  With Sturckow at the controls, the shuttle will conduct a flyaround
of the station, circling it 1< times before the shuttle's jets are
fired at 11:12 a.m. to drop Discovery into a lower orbit for final
separation from the station.

  The seven crewmembers aboard Discovery were awakened at 3:40 a.m. by
the sounds of "Brand New Day," played by Sting. The song was for
Helms, requested by her family and friends. She and her Expedition Two
crewmates are wrapping up five and a half months on orbit.

  Parked in Discovery's cargo bay is Leonardo, the Multi-Purpose
Logistics Module that brought 7,300 pounds of material to the station,
including equipment, supplies and two scientific racks. It is
returning to Earth with almost 2 tons of unneeded equipment from the
station, trash and personal effects of the Expedition Two crew.

  Expedition Three Commander Frank Culbertson, Pilot Vladimir Dezhurov
and Flight Engineer Mikhail Tyurin are beginning a science-intensive
increment that is scheduled to end with their replacement by the
Expedition Four crew late this year.

   Also on today's schedule for Discovery's crewmembers after
undocking is the deployment of a small science satellite called
Simplesat, designed to evaluate the use of inexpensive commercially
available hardware in space. It is designed to demonstrate GPS
attitude control and pointing in free flight. It will be
spring-ejected from a canister at the rear of the Shuttle's cargo bay.

   The Russians are all set to launch an unmanned Progress resupply
craft from the Baikonur Cosmodrome in Kazakhstan tomorrow at 4:24
a.m. Central time. It is the fifth Progress to be launched to the
station, and is scheduled to dock a little after 5 a.m.  on Thursday,
the day after the current Progress attached to the ISS is undocked
from the rear of the Zvezda Service Module to burn up in the
atmosphere with its load of trash.

  Discovery and the ISS are circling the Earth every 90 minutes at an
altitude of 246 statute miles. All systems are functioning well. 

 On Monday, August 20, 2001, 6:00 p.m. CDT, STS-105 MCC Status Report #21
reports:
 
 Discovery's astronauts, now consisting of the Expedition Two crew,
bid farewell to the International Space Station and the Expedition
Three crew and undocked from the complex at 9:52 a.m. CDT Monday after
more than a week of joint operations.  Frank Culbertson, Vladimir
Dezhurov and Mikhail Tyurin now will settle in to oversee activities
on the station for the next four months.

  The final farewells and hatch closing occurred at 7 a.m. Central
Monday just prior to closing the hatches and conducting leak checks
between the two vehicles.  Under control of Pilot Rick Sturckow,
Discovery gently backed away from the station to a distance of about
450 feet.  At that point, Sturckow performed a fly-around of the
complex allowing for photo documentation and a final look by Yury
Usachev, Jim Voss and Susan Helms at their home for the past five and
a half months.

  Returning with Discovery is the Leonardo Multi-Purpose Logistics
Module that brought equipment, supplies and two scientific racks to
the station. It is returning to Earth with more than a ton of
equipment, experiments, personal effects and unneeded hardware.

  Also today, Discovery's crewmembers deployed a small science
satellite called Simplesat, designed to evaluate the use of
inexpensive commercially available hardware in space.  It is designed
to demonstrate Global Positioning System attitude control and pointing
in free flight. It was spring-ejected from a canister at the rear of
the Shuttle's cargo bay.

  Tuesday is a day devoted to packing up the orbiter and checking its
landing systems for the planned return to the Kennedy Space Center
Wednesday.  Landing is set for just before Noon Central time with
weather conditions expected to be favorable with light winds and only
a slight chance of rain predicted in the area.

  Meanwhile, on the steppe of the Kazak desert, a Soyuz rocket is
poised to launch an unmanned Progress supply ship to the station
tomorrow at 4:24 a.m. Central time.  It is the fifth Progress to be
launched to the station, and is scheduled to dock a little after 5
a.m. Thursday, the day after the current Progress attached to the ISS
is undocked from the rear of the Zvezda module to burn up in the
atmosphere.

  The two spacecraft are at slightly different orbits, circling the
Earth every 90 minutes.  All systems are in excellent shape.
