RELEASE NO. 85-153 November 1985 

61-B MISSION TO DEPLOY THREE SATELLITES, 

ERECT SPACE STRUCTURES

Testing concepts for erecting structures in space and the deployment of three communications satellites 

will highlight mission 61-B, the 23rd Space Shuttle flight, scheduled for launch no earlier than Nov. 26. 

The 7-day mission will begin with the second night liftoff of the Shuttle program. Launch of Atlantis from 

Kennedy Space Center, FL, Pad 39A on its second flight is planned for a 9-minute window opening at 7:29 

a.m. EST. 

Atlantis will be placed in an orbit inclined 28.45 degrees to the equator. The initial orbit will be circular at 

an altitude of 218.5 miles. Orbital flight will extend as high as 235 miles for the satellite deployments. 

The seven-member crew includes Brewster H. Shaw Jr., commander, and Bryan D. O’Connor, pilot. 

Mission specialists are Mary L. Cleave, Sherwood C. Spring and Jerry L. Ross. Flying as payload 

specialists are Mexico’s Rodolfo Neri Vela and Charles Walker of McDonnell Douglas Astronautics CO. 

Highlights of the mission include deployment of Morelos-B, the second in a series of communications 

satellites for Mexico. Release from the payload bay will be initiated by mission specialist Spring on Flight 

Day 1. 

Morelos-B is a Hughes 376 satellite, the standard design used by many foreign nations and private 

companies. Morels will provide telephone, television and wire services to Mexico through a total of 22 

transponders. A PAM-D will boost the spacecraft to geosynchronous orbit. The satellite will be stationed at 

113.5 W. longitude over the equator south of Phoenix, AZ. The first Morelos spacecraft was deployed 

from the orbiter Discovery in June 1985. 

One Flight Day 2, another Hughes 376 satellite will be deployed for Australia. Aussat II is the second of 

three operations satellites for the government-owned Australian National Satellite System. The first Aussat 

was successfully deployed from Discovery in August 1985. 

The Aussat spacecraft has 11 12-watt and four 30-watt transponders to provide domestic communications 

to Australia’s 15-million population. The system also will be used to improve both maritime and air traffic 

control communications, relay digital data for business purposes, provide standard telephone 

communications and direct satellite-to-home television broadcasts to major cities as well as to the bush 

country. 

The deployment of this satellite also will be primarily the task of Spring. A PAM-D upper stage will boost 

the spacecraft to geosynchronous orbit. 

The 4,144-pound RCA Satcom K-2 communications satellite will be ejected from the payload bay on 

Flight Day 3 under the direction of mission specialist Ross. This will be the first deployment of a 

spacecraft on the uprated D-2 model of the Payload Assist Module (PAM D-2). 

Also aboard Atlantis for the 61-B mission is EASE/ACCESS, a combination of the two experiments 

designed to study an extravehicular method of construction in space. 

The Experiment Assembly of Structures in Extravehicular Activity (EASE) is a study of EVA dynamics 

and human factors in construction of structures in space. In the orbiter’s payload bay, Ross and Spring will 

assemble and disassemble an inverted tetrahedron consisting of six 12-foot beams. They will connect two 

of the beams to simulate Space Station construction and manipulate the assembled beam using the foot 

restraint and the Remote Manipulator System. 
Edited by Richard W. Orloff, 01/2001/Page 6

The Assembly Concept for Construction of Erectable Space Structures (ACCESS) experiment is a 

validation of ground-based timelines based on the neutral buoyancy water simulator at the Marshall 

Spaceflight Center, Huntsville, AL. Crewmembers will manually assemble and disassemble a 45-foot truss 

to evaluate concepts for assembling larger structures in space. 

The McDonnell Douglas Continuous Flow Electrophoresis System (CFES) again will be flown on mission 

61-B. This mission will test the mass production concept. Approximately 1 liter of raw hormone material 

will be purified over the first five days of flight. Payload specialist Walker will be performing sample 

evaluations throughout the flight. He will use syringe extractions for testing, and can make adjustments as 

necessary. Upon return to Earth, the material will be submitted to the Food and Drug Administration for 

testing. 

Also being flown again is 3M Co.’s DMOS, or Diffused Mixing of Organic Solutions, designed to grow 

crystals through the combination of organic solutions. DMOS was flown on orbiter Discovery in 

November 1984. Under the supervision of Cleave, the DMOS apparatus will build six types of organic 

crystals for 3M. These crystals will be larger and more pure than those grown in a positive gravity 

environment. 

A Getaway Special canister, holding an experiment for Telesat Canada, will be activated by Spring from 

the aft flight deck for a period of about 30 minutes. Six vapor deposition tubes will create metallic deposits 

for generation of crystal growth to make a mirror. 

The large format IMAX movie camera is aboard Atlantis to document the payload by activities, including 

the spacewalks. 

Also aboard is a hand-held Linhof large format camera for photography of Africa, particularly the areas of 

Ethiopia and Somalia. It will look for surface indications that might reveal the presence of water above or 

below the Earth’s surface. 

Mexican payload specialist Vela will conduct four experiments wile in orbit: transportation of nutrients 

inside bean plants, inoculation of group bacteria viruses, germination of three seed types, including 

abergon, lentil and wheat; and medical experiments which include measurements testing of internal 

equilibrium and volume change or the leg due to fluid shifts in zero-G. 

Both Vela and Walker will be testing for the rate of absorption of two medications into the bloodstream 

while in space, Tylenol and Scopedex. 

The orbiter Experiment (OEX), an onboard experimental digital autopilot software package, again will be 

tested on this flight. The autopilot software can be used with the orbiter, or another space vehicle such as 

the Orbital Transfer Vehicle which is under development, or even the Space Station. OEX is designed to 

provide precise stationkeeping capabilities between various vehicles operating in space. 

Deorbit burn for reentry will occur on orbit 109, with landing at Edward Air Force Base, CA on orbit 110 

at 6:23 p.m. EST, Dec. 3.

EASE/ACCESS

EASE: Experimental Assembly of Structures in Extravehicular Activity 

ACCESS: Assembly Concept for Construction of Erectable Space Structures 

The goal of the EASE/ACCESS experiments is to construct the first large structures in space. In both 

experiments, crew members assemble small components to form larger structures, just as may eventually 

be done to build the Space Station. 

Working in the Shuttle payload bay, astronauts will assemble the two structures. EASE and ACCESS, 

during two extravehicular activities (EVAs). The first EVA is devoted to experiments to study human 

performance of construction tasks in space. The second is dedicated to supplementary experiments that 

explore alternative construction techniques and practice Space Station maintenance scenarios. 

Experiment objectives are to: 

• Gain valuable on-orbit construction experience; 

• Compare assembly rates and techniques used in space to those used during ground assembly tests in 

neutral buoyancy water tank tests simulating the space environment; 

• Identify ways to improve erectable structures to ensure productivity, reliability and safety; and 

• Evaluate Space Station assembly and maintenance concepts and techniques. 

NASA’s Marshall Space Flight Center, Huntsville, AL is managing this first demonstration of microgravity 

construction techniques. EASE was developed in a joint effort between Marshall and the Massachusetts 

Institute of Technology. ACCESS was developed by NASA’s Langley Research Center, Hampton, VA. In 

preparation for this mission, these institutions have worked together, designing the structures, developing 

assembly methods in ground-based and neutral buoyancy simulations, and assisting in crew training. 

Both EASE and ACCESS are large space structures distinguished by different assembly methods and 

physical characteristics. Access is a “high-rise” tower composed of many small struts and nodes. ACCESS 

is assembled with crew members in fixed work stations. EASE is a geometric structure that looks like an 

inverted pyramid and is composed of a few large beams and nodes. Crew members move about during 

EASE assemblies, rather than working in fixed positions.

Edited by Richard W. Orloff, 01/2001/Page 16

ACCESS 

Height: Completely assembled - 45 feet 

 Assembly fixture - 11 ft. 

The entire structure consist of 93 tubular aluminum struts 1 inch in diameter. Thirty-three are 4.5-ft.-long 

struts; 60 are 6-ft.-long diagonal struts; 33 are identical nodal joints (1 bay or cell); 9 struts are used within 

and between bays; 6 struts join at one node. 

EASE 

Height: Completely assembled - 12 ft. 

The structure consists of 6 aluminum beams, each 12 ft. long, weighing 64 lb., containing four identical 

nodal joints. 

Assembly Equipment – The Mission Peculiar Equipment Support Structure (MPESS), which spans the 

15-ft. width of the payload bay, serves as a work platform and equipment carrier for the assembly 

experiments. Interface plates, attached to the support structure skeleton, allow easy mounting of 4-foot 

restraints and several hand restraints where astronauts can anchor themselves, making assembly procedures 

safer and easier. 

No tools are used for this first on-site assembly. The crew members “snap” together the prefabricated 

components to form each structure. Both the larger EASE beams and the smaller ACCESS struts are joined 

by nodes, clusters of sockets, which are locked into place by sleeves on the ends of a beam or strut. 

ACCESS nodes and struts are located in canisters mounted on the sides and top of the support structure 

near astronaut work stations; EASE beams are clamped to the front surface of the support platform, and the 

nodes are mounted on top. The EASE/ACCESS support structure and other equipment occupy 

approximately one-fourth of the payload bay. 

Crew Activity – The EASE/ACCESS experiments are supported by five of the seven 61-B crew members: 

the commander, the pilot, and the three mission specialists. The ability to make timely, on-the-scene 

judgments and to provide activity reports is central to the first orbital construction mission. Mission 

specialists Ross (EV-1) and Spring (EV-2) serve as structural assembly experts during two EVAs. They 

build the structures working from and around the MPESS. A third mission specialist, Mary Cleave, 

operates the orbiter robot arm to position crew members during some special construction tasks. Either the 

commander or pilot will oversee operations and assist with data collection such as filming activities.

EVA-1: Baseline Experiments 

The first space construction walk is planned for 6-hours duration using crewmembers Ross and Spring. 

The EVA begins with the ACCESS experiment. The baseline experiment assembly technique requires both 

crew members to be positioned in designated work areas: one stands in foot restraints at the support 

structure base and the other works in similar restraints on top of the work platform. This “assembly line in 

space” technique allows rapid construction for measurements of productivity. 

ACCESS Assembly Procedures: 

1. Unstow assembly fixture, raise it to a vertical position, and unfold three guiderails; 

2. Remove struts and nodes from three stowage canisters; 

3. Connect nodes and struts on assembly fixture, forming one cell or bay; 

4. Slide finished bay upward along guiderails to the top of the assembly fixture; 

5. Repeat procedure to construct nine more bays; and 

6. Disassemble by sliding bays down, removing and stowing nodes and struts. 

The second half of this EVA is devoted to the EASE experiments. To measure learning and productivity, 

the structure is assembled and disassembled repeatedly. Investigators are planning for at least six full 

assemblies during the EVA. The baseline experiment techniques allow astronauts to move about freely, 

using foot restraints as necessary. 

EASE Assembly Procedures 

1. Unstow beams clamped to the front of the work platform; 

2. Connect three vertical beams to a node attached to the top of the work platform; 

3. Connect three horizontal beams to the three vertical beams by nodes; and 

4. Repeatedly assemble and disassemble structure 

The EVA crew members can alter assembly method as necessary and will do as many assemblies as time 

allows.

EVA-2: Supplementary Experiments 

To enhance the value of this mission for space Station planning, several additional tasks will be undertaken 

with both structures on a second space construction walk involving Ross and Spring. Supplementary 

experiments include manipulating the large space structures, simulating Space Station maintenance 

operations, installing flexible cable and using the orbiter robot arm to assist the astronauts during structural 

assembly. The second EVA begins with the construction of nine ACCESS bays using the baseline 

experiment technique. One crew member then is positioned on the manipulator foot-restraint work station 

and moved around by Cleave from inside the flight deck. The manipulator work station is outfitted with a 

specially designed ACCESS component carrier. 

Second ACCESS Assembly Procedures: 

1. Assemble first nine bays from fixed work stations mounted to the support structure; 

2. Pack component carrier with struts and nodes needed to construct one bay; and 

3. Move MFR crew member on the RMS to the top of the existing ACCESS bay where he completes the 

tenth bay. 

ACCESS Maintenance and Repair Tasks:

When 10 full bays are constructed, Space Station maintenance and repair tasks scheduled to be practiced 

are: 

1. To stimulate stringing electrical cable, both crew members will string flexible cable along the 

ACCESS truss framework; 

2. To rehearse repair of a damaged structure, MFR crew member removes and replaces struts and nodes; 

3. To practice handling large frameworks, MFR crew member removes entire structure from the 

assembly fixture and maneuvers it in the payload bay. Structure is reattached, disassembled, and 

stowed. 

During the second half of the EVA, EASE is constructed with one crew member positioned in the foot 

restraint. The other works at the equipment support structure base, using foot restraints as necessary. 

Second EASE Assembly Procedures: 

1. Unstow beams clamped to front of work platform; 

2. Move MFR crew member, equipped with beams and nodes, to the top of the EASE structure; 

3. Attach three vertical beams to a node mounted on top of the support structure; and 

4. Connect three horizontal beams to three vertical beams with nodes to complete structure. 

EASE Maintenance Tasks: 

1. To practice maneuvering large geometric structures, crew members remove entire structure and move 

it around; 

2. Crew members connect two EASE beams to form a 23.5-ft., 130-lb. beam; and 

3. To practice handling long structures in space, crew members transport and manipulate the connected 

beams.

Data Collection 

Careful observation of crew activities is needed to understand the human factor elements of space 

construction. Aspects such as learning, productivity and fatigue are important as well as the biomedical 

effects of working during EVAs. During the EVAs, researchers from Marshall, MIT and Langley will 

monitor the mission from Johnson Space Center. Video cameras located in the orbiter payload bay and on 

the robot arm will be used to record images of each crew member at work. Movie cameras mounted in the 

aft-flight deck windows will be synchronized to generate a 3-D film which will be used to analyze 

astronaut motions. 

Following the flight, investigators will retrieve more detailed information from the video and film. The 

film will be used to reconstruct 3-dimensional images of astronauts at work during the experiments to 

derive body positions, equipment locations, and any difficulty in completing a task. Planners will use 

mission data to construct computer models for completing similar EVA tasks. In addition to recorded data, 

crew reports on activities and tasks will be provided to investigators. The crew members’ suits are 

instrumented to monitor pulse rate and oxygen use to that biomedical profiles on working in space can be 

obtained.

MORELOS COMMUNICATIONS SATELLITE

Morelos is the second of two spacecraft to be launched by the Space Shuttle for the Secretariat of 

Communications and Transportation, Mexico. Morelos will provide advanced telecommunications tot he 

most remote parts of Mexico: educational TV, commercial programs over the national TV network, 

telephone and facsimile services and data and business transmissions. Television programming will 

originate in at least 12 principal cities. Cultural, educational and athletic events will be televised 

nationwide. The Hughes Space and Communications Group is prime contractor. 

Morelos is a spin-stabilized, gyrostat design with a despun antenna and communications payload. Two 

cylindrical solar panels, one fixed and one extendible, supply prime power to the spacecraft. At launch, 

Morelos is mated to the PAM-D stage with the antenna reflector and aft solar panel are stowed. The PAMD stage supplies the necessary impulse for injection into a transfer orbit. Shortly after separation of the 

spacecraft from the orbiter Discovery, an omnidirectional antenna is deployed. 

Morelos’ two cylindrical solar panels telescope when the spacecraft is in orbit. In launch position, with 

antenna reflector folded down, Morelos is 9 ft., 4 in. high. In orbit with panels extended and antenna 

erected, it is 21 ft., 8 in., high. It is 7 ft., 1 in. in diameter and weighs 1,422 lb. at the beginning of life I 

orbit. Four thrusters using 293 lb. of hydrazine propellant, provide orbit and attitude control during the 

satellite’s 9-year planned mission life. 

From low-Earth orbit, the cradle’s protective sunshield is opened and a table at the base spins the satellite 

to 55 rpm to provide gyroscopic stability. Four springs push the satellite into space and 45 minutes later, an 

onboard sequencer fires the McDonnell Douglas payload assist module (PAM). A Morton Thiokol Star 

apogee kick-motor places the satellite into a circular synchronous orbit. 

Morelos-B will not be activated once it achieves its geosynchronous orbit. Rather, it will remain inert for a 

period up to two years, drifting naturally to its final longitude. Near its operating position, the reflector 

antenna and electronics shelf are despun and achieve close pointing accuracy. The satellite drifts into final 

orbit and is placed in operating position with onboard thrusters. 

NASA has been reimbursed $10 million by the Mexican government for launch services associated with 

the Morelos-B satellite. 

MEXICAN PAYLOAD SPECIALIST EXPERIMENTS 

Rodolfo Neri Vela will be performing a series of mid-deck cabin experiments as well as take photographs 

of Mexico. The experiments are: 

Effects of Spatial Environment on the Reproduction and Growing of Bacteria (REPGROW) – 

Cultures of Escherichia coli B-strain bacteria will be mixed on orbit with different bateriophages that attack 

the Escherichia coli and subsequently, are observed for possible changes and photographed as required. 

Transportation of Nutrients in a Weightless Environment (TRANSPORT) – Ten plant specimens will 

be planted in containers that will allow a radioactive tracer to be released on orbit for absorption by the 

plants. At selected intervals, each plant will be sectioned and the segments will be retained for post-flight 

analysis to determine the rate and extent of absorption. 

Electropuncture and Biocybernetics in Space (ELECTRO-PUNCTURE) – The objective of the 

experiment is to validate electropuncture theories. These theories state that disequilibrium in the behavior 

of human organs can be monitored and stimulated by using electric dc current in specified zones. This 

experiment is performed by measuring the conductance of electricity in a predetermined zone. If a

disequilibrium is detected, exercises or stimulus will be applied for a certain period until the value of the 

conductance falls into the normal range. 

Effects of Weightlessness and Light on Seed Germination (SEEDS) – Seed specimens of amaranth, 

lentil and wheat will be planted on orbit during Flight Day 2 in two identical containers. Subsequently, one 

container will be exposed to illumination and the other to constant darkness. Photographs of the resulting 

sprouts will be taken every 24 hours. One day prior to landing, the sprouts will be submitted to a 

metabolical detention process for subsequent histological examination on Earth to determine the presence 

and localization of starch granules.

AUSSAT -2 

Aussat, the Australian national satellite communications system, will provide a wide range of domestic 

services to the entire continent and its offshore islands. This includes direct television broadcast to 

homesteads and remote communities, high-quality television relays between major cities, digital data 

transmission for both telecommunications and business use, voice applications for urban and remote areas, 

centralized air traffic control services and maritime radio coverage. Aussat-2 is the second in a system of 

three to be operated by Australia’s national satellite company, Aussat Proprietary Ltd. 

Aussat-2 uses two telescoping cylindrical solar panels and a folding antenna for compactness during 

launch. After the satellite nears its orbital position, the antenna erects and the outer solar panel deploys, 

exposing the inner solar array. 

Aussat’s antenna system will provide seven transmit beams and three receive beams. Five transmit beams 

serve the Homestead and Community Broadcasting Satellite Service: four contiguously placed over the 

western, central, northeast and southeast regions of the Australian content and one over Papua, New 

Guinea. The other two are national beams which provide continental coverage for Fixed Satellite Service. 

Aussat will carry 15 channels, each 45 MHz wide. Four will use high-power, 30-watt traveling wave tube 

amplifiers (TWTAs) to provide radio and television services to Australia’s remote areas. The remaining 11 

channels will operate with 12-watt TWTAs. It will be possible to connect the communications channels 

individually to the transmit beams by ground command. This arrangement will provide traffic flexibility 

for the system. 

The satellite’s diameter is nearly 7.2 ft. Stowed for launch its height is 9.2 ft. In orbit, with antennas 

deployed and aft solar panel extended, the height will increase to 71 ft. Its initial on-station weight will be 

about 1,322 lb. 

The Aussat satellites, with a mission life of 7 years, will operate at the 14/12 GHz Ku-band. Two 

spacecraft will be located above the equator just north of Papua, New Guinea, at 156 degrees and 164 

degrees east longitude. The third satellite will be located at 160 degrees east longitude. 

The master control station for the Aussat system will be in Sydney and backup control equipment will be 

installed in Perth. Monitoring equipment will be installed at Earth stations in Sydney, Perth, Brisbane and 

Adelaide. 

Hughes Space and Communications Group built the three satellites and two telemetry, tracking, command 

monitoring stations. 

NASA has been reimbursed $9.5 million by the Australian government for launch services associated with 

the Aussat 2.

RCA SATCOM K-2

Two of a planned fleet of three communications satellites, operating in the Ku-band part of the spectrum, 

will be launched for RCA American Communications, Inc., in 1985. The third is scheduled for launch in 

1987. 

Each of the spacecraft, designated Satcom K-1, K-2 and K-3, will have 16 channels operating at 54 MHz 

usable bandwidth wile providing coverage of the continental 48 states. The spacecraft are designed to 

provide coverage to the continental 48 states, or to either the eastern half or western half. 

The first of the series to be launched is Satcom K-2, on STS 61-B, which has been assigned an orbital 

position of 81 degrees west longitude. Satcom K-1, assigned an orbital position of 85 degrees west 

longitude, is to be orbited aboard the Shuttle Columbia on Dec. 18. 

The three-axis stabilized spacecraft are equipped with power, attitude control, thermal control, propulsion, 

structure, and command ranging and telemetry systems necessary to support mission operations from 

launch vehicle separation through 10 years of operational life in geosynchronous orbit. 

This new generation of spacecraft carries 45-watt transponders, which permits the use of Earth station 

antennas a small as 3 ft. in diameter. Because Ku-band frequencies are not shared with terrestrial 

microwave systems, antennas served by the satellites can be located within major metropolitan areas 

characterized by heavy terrestrial microwave traffic. 

Following the launch of Satcom K-2, it will be placed into a 23,000-mi. geosynchronous orbit. After this, 

the 280-square-foot solar panels will deploy from the 67-by-84-by-60-in. main spacecraft structure. The 

spacecraft will then be tested for in-orbit operation and locked into its orbital slot of 81 degrees W. 

longitude. 

The spacecraft main structure contains all electronic boxes, batteries, propulsion and attitude control 

equipment on eight honeycomb panels. Including the antenna feedhorn tower, the maximum spacecraft 

main body height is 90 in. Transponders and housekeeping components are mounted on four panels, two 

each on the “north” and “south” sides of the spacecraft. 

Additional housekeeping equipment is mounted on a base panel, facing away from the Earth. The Earthfacing panel provides a mounting surface for the communication antenna reflector with its component feed 

assembly, a command and telemetry antenna and the Earth sensors for attitude control. 

The Satcom KU-band communications capability is provided by 15 45-watt traveling wave tube amplifiers 

for each of the 16 channels and six traveling wave tube amplifiers for redundancy. The 16 channels are set 

up in two groups of eight, each group contains three spare amplifier tubes. Each of the 16 channels uses 

active frequency and polarization interleaving to permit the simultaneous use of each. The channels have a 

usable bandwidth of 54 MHz. 

The spacecraft is controlled in geosynchronous orbit by a high speed momentum wheel which has active 

speed control and wheel-axis roll trim. Momentum damping is provided by onboard magnetic torquers with 

backup provided by onboard reaction control system hydrazine thrusters. 

Main spacecraft power comes from the deployed solar array with three battery systems providing backup 

power. 

Satcom K-2, owned and operated by RCA American Communications (RCA Americom), is one of three 

Ku-band domestic communications satellites operating in the 12 to 14 Gigahertz range. There are 16 

operational transponders and six spares, each transmitting 45 watts of power, more than the 12 or 30 watts 

used for C-band transponders.

RCA Satcom Ku-2 is a version of the RCA 4000 three-axis, stabilized spacecraft, similar in appearance to 

the ASC-1 satellite deployed from Discovery in August 1985. It will provide television programming in 

three ways: 

Satellite Master Antenna Television (SMATV) will provide entertainment and educational services. 

Receiver antennas will be installed at multi-unit residential complexes such as condominiums and 

apartments, hotels, hospitals and schools. 

Direct-to-Home services will distribute a wide range of programming choices to homes far removed from 

cable systems or standard over-the-air television stations. 

The syndication System will deliver time-sensitive programming to commercial broadcast television 

stations. 

PAM D-2 

The PAM D-2 is instrumented with radio frequency telemetry which will downlink data to tracking aircraft 

during the burn of the solid rocket motor, a mission requirement for the first flight of a PAM-D2. This 

uprated, upper stage is identical to the PAM-D, except for size and weight. The spin-up will be noticeably 

slower due to the larger mass and inertial components of the payload. PAM-D2 is designed to lift up to 

4,200 lb. to geosynchronous orbit, compared to the 2,800-lb. PAM-D version.

DIFFUSIVE MIXING OF ORGANIC SOLUTIONS

The Diffusive Mixing of Organic Solutions (DMOS-2) experiment is intended to grow organic crystals in 

near-zero gravity. 3M scientists hope to produce single crystals that are purer and larger than those 

available on Earth and will study their optical and electrical properties. DMOS experiments also will 

include an investigation into the process of fluid mixing within the DMOS cells. 

One of the potential applications, of the crystals 3M is growing, is making optical devices comparable to 

electronic devices, though much faster. Possible uses include optical switches and computers that process 

information with light instead of electricity. 

The DMOS-2 experiment will be flown in six football-size chemical reactors carried in the mid-deck area. 

The reactors, or cells, are housed in the Experimental Apparatus Container supplied by NASA. 

Each cell consists of three chambers into which organic liquids will be loaded. In space, valves between 

the chambers will be opened and the liquids allowed to mix. 

The experiment will be controlled by the Generic Electronic Module (GEM), a bubble-memory computer 

about the size of a hatbox that also was used successfully to operate 3M’s two previous space experiments 

(DMOS-1) and Physical Vapor Transport of Organic Solids). The GEM has a hand-held keyboard display 

that lets the crew control the experiment. 

The hardware for DMOS-2 is similar in size and function to that of DMOS-1. However, the new hardware 

is of modular construction and includes a quick-change cell installation feature, larger loading holes for 

chemicals, a more positive valve-opening assembly that uses a lever instead of the cam-and-roller of 

DMOS-1 and electronics mounted on each cell instead of on a single control board. 

Dr. Marc Radcliffe, a chemist with 3M, is principal investigator and Dr. Earl Cook, a 3M physicist, is coinvestigator. 

Two of the cells are devoted to a study of the physics of the mixing process. One cell uses a yellow and 

blue dye with light density methanol in the middle chamber and the other cell uses a red dye in the middle 

with heavier density heptane in the end chambers. These will help explore variations in mixing based on 

density differences. 

Of the four crystal growth experiments, two are devoted to studies of the molecular growth and ordering 

under near ideal conditions in space and the other two examine the way crystals pack together and how this 

packing affects their electro-optical properties. One of the crystal growing experiments uses cyanine 

tosylate and triethylammonium oxonol in chloroform. The other crystal growth and both crystal packing 

experiments use proprietary chemicals. 

All six cells will be activated just prior to the first sleep period and will remain active throughout the flight. 

An hour prior to landing, the two fluid-mixing cells will be closed so that entry forces don’t change the dye 

concentrations. In the crystal experiments, the valves between cell chambers will be left open to insure no 

damage to crystals which may have been growing in the valve area.

GETAWAY SPECIAL EXPERIMENT 

(Telesat of Canada) 

To stimulate Canadian student interest in the space program, Telesat sponsored a national competition 

soliciting science experiments from high school students throughout Canada. The contest resulted in 72 

entries from nearly 300 Canadian students. After screening by Telesat Canada and Canadian National 

Research Council scientists, seven finalists were selected for judging by a panel which included Dr. Stuart 

Smith, chairman of the Science Council of Canada, Dr. Alphonse Ouimet, a member of the Telesat Board 

of Directors and Dr. Jeff Hoffman, NASA astronaut. 

The panel selected the experiment submitted by Daniel Rey and Jean-Francois Deschenes of the Ecole 

Secondaire Charlebois, Ottawa, Ontario. Their experiment, entitled “Towards a Better Mirror,” proposed to 

fabricate mirrors in space that would provide higher performance than similar mirrors made here on Earth. 

On Earth, oxidation lowers the reflectivity of mirrors as air interacts with the metal used in mirror 

production. The experiment uses vapor deposition. The experiment assembly is built on an aluminum Tbeam support structure which holds six vapor deposition tubes. The products of the experiment will be 

tested post flight using a number of sophisticated optical techniques to determine precise measurements of 

the on-orbit coating process. These measurements will be used to compare the space-made mirrors with 

control mirrors made on Earth during the flight.

PROTEIN CRYSTAL GROWTH EXPERIMENT 

The hand-held Protein Crystal Growth Experiment, conducted by payload specialist Walker, it is one of a 

series of experiments being flown to study the possibility of crystallizing biological materials such as 

hormones, enzymes and other proteins. Successful crystallization of these materials, which are very 

difficult to crystallize on Earth, will allow their three-dimensional atomic structure to be determined by Xray crystallography. Knowledge of the atomic structure hopefully will lead to a capability to develop 

pharmaceuticals to enhance or inhibit the protein’s function on a rational manner. 

The experiment consists of two vapor diffusion crystal growth units and one dialysis growth unit. Each 

vapor diffusion unit is 3 in. wide, 14 in. long and 1/2 in. thick and contains 24 small crystal growth 

chambers. Each f the 48 chambers is equipped with a porous liner saturated with precipitating agent such 

as alcohol or saline solution. A small drop of protein solution will be injected into each chamber shortly 

after entering orbit. 

Up to six of the growth chambers will be “seeded” by injecting a microscopic particle crystallized protein 

into the droplet to form a nucleus for a larger crystal. 

The dialysis unit is a block of Lexan (about 1 by 1 in. and 1/2 by 5 in.) with an internal cylindrical cavity 

containing small glass ampoules of precipitating solution suspended in water. Also suspended in the cavity 

are three small dialysis buttons activated by shaking the unit, causing the fragile glass ampoules to break, 

and releasing the precipitating agent to mix with the water. The proteins in the dialysis buttons are then 

crystallized through dialysis. 

After activation and photography, the units are stowed to allow crystallization to proceed in a vibrationfree, gravity-free environment. At the end of the mission, the units are photographed again and prepared 

for entry, landing and removal.

CONTINUOUS FLOW ELECTROPHORESIS EXPERIMENT (CFES) 

The McDonnell Douglas continuous flow electrophoresis device will make its seventh trip into space 

aboard Atlantis on flight 61-B. The objective of this mission is to separate a sufficient quantity of 

biological material for animal and clinical testing of a breakthrough pharmaceutical. 

Charles D. Walker, McDonnell Douglas engineer and payload specialist, will monitor the operation of this 

machine and conduct biological assays. This is Walker’s third flight as payload specialist. 

The continuous flow electrophoresis device will operate for about 175 hours during the 7-day mission. It is 

expected that about 66 hours of processing time will be necessary to purify the approximately 1 quart of 

concentrated protein material on board. 

To ensure that the desired hormone is being separated and collected within the fluid modules, once each 

day Walker will run a test on a sample of material taken from the collection streams. Using assay material 

carried on board separately, he will test for hormone presence in the fluid. 

Walker will test daily for the presence of contamination. These tests will be made by withdrawing small 

samples of fluid from five locations and incubating them in vials previously loaded with freeze-dried 

reactants. Post-flight results from mission 51-D in April 1985 showed that preflight levels of cleanliness 

were maintained. 

After separation of the biological material is complete, Walter will reconfigure the CFES device to permit 

additional research on the effects that varying sample concentrations have on the efficiency of the process. 

Several samples of differing concentrations will be tested to determine the optimum concentration ratio of 

sample to buffer.

IMAX 

The IMAX project is a cooperative effort between the Canadian IMAX company and NASA. The system 

uses a specially designed 70 mm film camera to record color motion images on specially sprocketed film. 

During this flight, the IMAX camera will be used to document payload bay activities associated wit the 

EASE/ACCESS assembly during the two planned space construction walks. 

The camera is mounted in the payload bay in a pressure-sealed container with a viewing windows. The 

windows has a sliding door which opens when the camera is in operation. The camera is controlled from 

the aft flight deck, exposing the film through a 30 mm fisheye lens. 

IMAX cameras flew on STS missions 412-C, 41-D and 41-G to document payload bay and orbiter middeck and flight-deck crew activities along with spectacular views of space and the Earth. Film from those 

missions is included in the IMAX production “The Dream is Alive.”
