EIGHTEENTH SHUTTLE FLIGHT TO FEATURE INTERNATIONAL 

CREW AND CARGO 

The upcoming flight of Discovery, the 18th of the Space Shuttle program, will be distinctively international 

as NASA flies the first French and Arab payload specialists and a cargo that includes American, Mexican 

and Arabian domestic communications satellites. 

Also aboard are three west German small self-contained payloads, also known as Getaway Specials. 

Discovery's fifth launch is scheduled for no earlier than 7:33 a.m. EDT on June 17, 1985, from Complex 

39-A at the Kennedy Space Center, Fla. 

Aboard the ship will be a crew of seven, commanded by Shuttle veteran Daniel Brandenstein, pilot on the 

eighth Shuttle mission. He will be joined by pilot John Creighton and mission specialists Shannon Lucid, 

Steven Nagel and John Fabian. Fabian is also a Shuttle veteran, having flown on STS-7. 

French Payload Specialist Patrick Baudry will carry out biomedical experiments similar to those flown by a 

French cosmonaut aboard a Soviet manned mission. Sultan Salman Al-Saud will conduct 70 mm 

photography over Saudi Arabia, photograph a fluids experiment and participate in the French Postural 

Experiment. 

Discovery's payload bay will have a full load with the three communications satellites, a 

deployable/retrievable spacecraft called Spartan 1 and six Getaway Special canisters. Several mid-deck 

experiments will also be flown, including one for the Strategic Defense Initiative Organization and a 

materials processing furnace. 

The Shuttle will be launched from KSC into a 220-mile orbit inclined 28.45 degrees to the Earth's equator. 

The mission is planned for 7 days. 

The Mexican communications spacecraft is called Morelos-A. It is a version of she Hughes US 376 

satellite, a number of which have already been deployed by the Space Shuttle. Morelos-A is the first of two 

domestic communications satellites that will provide advanced telecommunications to even the most 

remote parts of Mexico. 

Morelos will be deployed on the first day of the flight on Discovery s sixth orbit of the Earth. 

Arabsat-A is owned by the Arab Satellite Communications Organization. Built by Aerospatiale, it will 

provide telecommunications links between the member nations. Arabsat will be deployed from the Shuttle 

5 cargo bay about 26 hours into the flight during orbit 18. 

Telstar 3-D is an American domestic communications satellite owned by American Telephone and 

Telegraph (AT&T). Telstar 3-D will provide telecommunications services to the continental United States, 

Alaska, Hawaii and Puerto Rico. It will be deployed from the Shuttle on orbit 32 just before the 48-hour 

point in the mission. 

All three communications spacecraft will be spring-ejected from the cargo bay of the orbiter. On each, a 

small attached rocket called the Payload Assist Module will be ignited about 45 minutes after deployment. 

Between deployment and PAM ignition, the Shuttle will be maneuvered to a safe distance. The end 

effector camera on the robot arm will be used to observe the perigee kick motor firing on each of the 

spacecraft. 
Edited by Richard W. Orloff, 01/2001/Page 6

The PAM stage propels a satellite to a transfer orbit which reaches out as far as 22,300 miles above Earth. 

A second small rocket motor is then fired on each spacecraft to circularize the orbit at that distance. The 

period of a satellite in geosynchronous orbit is synchronized with the Earth's rotation so it always remains 

over the same region of the globe. 

This characteristic enables continuous communications services to he provided to a broad region of Earth 

directly beneath the spacecraft. 

Spartan is designed to carry a variety of experiments. The name is an acronym standing for Shuttle Pointed 

Autonomous Research Tool for Astronomy. It can be deployed, flown in formation with the orbiter and 

then can be retrieved and returned to Earth. 

Using the Shuttle’s remote manipulator arm, Spartan will be deployed on flight day 4 and will be retrieved 

on the sixth day of the mission. 

X-Ray sensors aboard Spartan 1 will search for hot gas clouds in galaxy clusters and perform a survey of 

X-Ray sources in our own galaxy -- the Milky Way. 

The Spartan program is an extension of the NASA sounding rocket program and is sponsored by the 

Goddard Space Flight Center, Greenbelt, Md., to provide low-cost, high-quality observations. 

Payload specialist Baudry and the French biomedical experiments had been scheduled to fly on mission 51-

E in early March. When that flight was canceled, Baudry and the experiments were reassigned to flight 51-

G. 

The French Postural Experiment (EPE) will help scientists better understand the human body's postural 

adaptation in space, while the French Echocardiograph Experiment will investigate other aspects of space 

adaptation. 

Another middeck experiment, the Automated Directional Solidification Furnace, is located in three 

middeck lockers and will be used for materials processing research. 

The Strategic Defense Initiative Organization is flying an experiment called the High-Precision Tracking 

Experiment. 

There are six Getaway Specials mounted along the sides of Discovery's payload bay. The three West 

German payloads will be used to study materials processing in space and the behavior of liquid propellants. 

The U.S. Air Force and U.S. Naval Research Laboratory are sponsoring an investigation of the ultraviolet 

radiation environment in space in another Getaway Special canister. A fifth canister contains a package of 

nine student experiments in biological and physical science. A Goddard Space Flight Center investigation 

of a developmental beat transfer system is in the sixth canister. 

Discovery 5 return to Earth is planned to begin with a deorbit burn at 7 days 40 minutes into the flight on 

orbit 111. 

Landing on the dry lake bed at Edwards Air Force Base, Calif., will occur almost exactly I hour later, at 

about 9:14 a.m. EDT, June 24, 7 days, 1 hour and 41 minutes mission elapsed time.

FRENCH MIDDECK EXPERIMENTS 

The French Echocardiograph Experiment (FEE) and the French Postural Experiment (FPE) will fly on 

flight 51-0 as part of a cooperative project with the Centre National d’Etudes Spatiales (CNES) of France. 

The objectives of these experiments are to obtain on-orbit data regarding the response to weightlessness off 

the cardiovascular and sensorimotor systems. The system was previously flown on a Soviet Salyut mission 

in July 1982. 

These experiments accompany and will be performed by the French payload specialist Patrick Baudry with 

participation from other crew members. 

French Echocardiograph Experiment (FEE) 

The human cardiovascular system is adapted to compensate for the constant pull of gravity on Earth. 

During the first few days of spaceflight the crew is subjected to some significant changes as their systems 

adapt to the sharp reduction of gravitational effects. Such effects include the temporary pooling of blood in 

the head and upper torso, with changes in the size of some heart cavities and flow rates in major arteries.. 

Data on these changes and the readaptation to gravity after the mission have important implications for 

crew health and safety. 

The French echocardiograph uses a non-invasive, ultrasonic technique to obtain data on these events. The 

equipment weighs 176 pounds and is contained within two middeck double lockers. One double locker 

holds the electronics; the second holds the video tape recorder, the control monitor and a stowage drawer. 

Payload specialist Baudry will perform the FEE supported by mission specialist Shannon Lucid. The 

experiment will be performed at launch plus 4 to 6 hours and one other time during that day. Baudry and 

Lucid will then separately perform the experiment at approximately the same time each flight day. Preflight 

and post flight collection sessions will be required to correlate data collected in flight. 

The echocardiograph was built by Matra-Interelec, Paris, and the sensors were built by the Tours-based 

company, Vermon. The principal investigator is L. Pourcelot, University of Tours, and Dr. Antonio Gull, 

Toulouse Hospital. The FEE is managed by the Laboratoire de Biophysique Medicale, Faculte de 

Medecine, Tours, France. 

French Postural Experiment (FPE) I 

The human sensorimotor functions may be categorized into four areas: muscular tone, posture, orientation 

and movement. All these functional modes interact to operate within the constant field of gravity 

experienced on Earth. Without the physical bias and point of reference provided by gravity, these sensor Imotor functions must adapt. It is the objective of the EPE to learn more of this adaptive process. A better 

understanding of this process may provide new insights as to how these functional modes interact on Earth. 

Parametric measurements of electromyographic activity of muscles, angular head movement and up-anddown eye movement will be conducted. Measurements will be obtained using biochemical electronic 

sensors, data tape recorders and a camera. The five in-flight objectives of the FPE are: posture and 

movement; posture and vision; vestibule-ocular reflex; optokinetic nystagmus (involuntary oscillation); 

and spatial memory. 

During in-flight operation, the experiment will be conducted on a non-interference basis with the planned 

crew activity once a day by two crewmembers throughout the mission. Baudry and the Saudi payload 
Edited by Richard W. Orloff, 01/2001/Page 15

specialist will be trained to perform the FPE and to assist each other. Each experimental session will 

require 65 minutes, including set-up and calibration, plus an additional 30 minutes for unstowage and 

stowage. 

The FPE equipment weighs 17.6 lb. and is stored in two mid-deck lockers. The experiment hardware was 

developed by the Centre National de Recherche Scientifique (CNRS) Laboratoire de Physiologie 

Neurosensorielle, Paris, and built by three companies -- Aeta, of Velizy; Erems, of Balma: and Comat of 

Toulouse --under a CNES contract. principal investigators are Prof. Alain Berthox and Prof. Francis 

Lestienne, CNRS. The experiment is managed by Laboratoire de Physiologie Neurosensorielle, CNRS.

ARABSAT COMMUNICATIONS SATELLITE 

Arabsat is a communications spacecraft designed for launch by the Space Shuttle orbiter. Once deployed, it 

is boosted to its operational synchronous orbit of about 22,300 statute miles by a Payload Assist Module-P 

(PAM-D). Main body of the spacecraft is rectangular with deployable solar arrays extending north and 

south along the pitch axis in flight. A graphite epoxy central cylinder transmits loads from the satellite 

through the adapter to the launch vehicle. The cylinder also houses the propulsion system's propellant 

tanks, the antenna feed and reflector brackets for high stability. 

Two solar array wings are independently oriented toward the sun by rotational drive assemblies. The arrays 

are deployed once the spacecraft has ended the transfer orbit phase of flight. 

Once in geosynchronous transfer orbit, the outer panel on each array is deployed with release of four 

primary stirrups which hold the arrays. After final firing of the apogee motor, the remaining three panels 

are deployed. 

C-band transmit and receive antennas are on the east and west sides of the spacecraft. An S-band antenna 

faces Earth. 

A low-thrust, l00-lb. bipropellant apogee engine is in the main body. Providing a high specific impulse, it 

is fired at the transfer-orbit apogee to arrive at the precise geosynchronous orbit. 

About 80 seconds after deployment, when Arabsat is about 200 feet from Discovery, the PAM-D is 

jettisoned by a signal from the master control station in Riyadh, Saudi Arabia, through the COMSAT 

Launch Control Center, Washington, D.C. Actuators then deploy Arabsat's solar panels. 

The Arabsat spacecraft weighs 2,800 lb. and the PAM-D, 4,863 lb. 

ARABSAT PAYLOAD SPECIALIST ACTIVITIES 

Sultan Salman Al-Saud, the Saudi Arabian Arabsat payload specialist, will take part in four scientific 

investigations: Earth Observation, Phase Separation, Ionized Gas and French Postural Experiments. 

Al-Saud will photograph Saudi Arabia during Discovery's 49 daylight passes over its southwestern region 

with a 70 mm camera from orbit. The photographs will be studied by Saudi scientists at the research 

institute, the University of Petroleum and Minerals in Dhahran, Saudi Arabia. They also will be compared 

with previous data from multispectral scanner, thematic mapper and radar images (SIR-A and SIR-B). 

Analysis will cover geological features, sand dune morphology, hydrogeological features, turbidity in the 

Red Sea, urban areas and forestry. 

In another experiment, two liquids which do not mix on Earth will be studied in microgravity. They are 

referred to as "phases." Using Phase Separation Experiment hardware developed at the NASA Marshall 

Space Flight Center, Al-Saud will place various concentrations of Saudi, Kuwaiti and Algerian oils mixed 

with water in a hand-held, transparent Plexiglas container with 15 chambers, each having a small metal 

mixing ball. He will shake the container and mount it in front of a fluorescent light, then photograph the 

separation and record his observations. 

The film will be studied by Saudi investigators at the university of petroleum and Minerals and the 

Marshall Space Flight Center. Results may shed light on the process of enhanced oil recovery and behavior 

of oil spills and pollution. 
Edited by Richard W. Orloff, 01/2001/Page 17

The Ionized Gas Experiment (ICE) requires that Sultan Salman Al-Saud, using the Orbiter Discovery’s TV 

cameras, record thruster firings in specified configurations to study the mechanics of thruster plumes and 

the degree off Ionization produced. This experiment is part of a Saudi Arabian student Ph.D. thesis at Stanford university. purpose is to assess the thruster plumes effect on operations measurements and 

communications associated with space vehicles. The data obtained also will be analyzed at the university of 

petroleum and Minerals for a better understanding of the impact of gas particles on solid surfaces. Al-Saud 

also will photograph the Arabsat satellite's rocket engine firing. 

Al-Saud will assist French payload specialist Patrick Baudry in the postural Experiment on the adaptation 

mechanism of the sensory motor activities. This includes posture stabilization and orientation and the role 

of vision in posture control and reflex mechanisms that stabilize the retina. Requiring about 3 hours, the 

experiment will be performed before, at the beginning, during the middle and last day of flight two times a 

day. 

In another activity, Al-Saud will try to observe the crescent of the new moon with the unaided eye from 

orbiter windows as it becomes visible close to the western horizon immediately after sunset June 17 or 18 

at the end of the Muslim religious holiday, Ramadan

MORELOS COMMUNICATIONS SATELLITE 

Morelos is one of two spacecraft scheduled for launch by NASA's Space Transportation System for the 

Secretariat of Communications and Transportation, Mexico. It will provide advanced telecommunications 

to the most remote parts of Mexico including 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 extendable, supply prime power to the spacecraft. At launch, 

Morelos is mated to the PAM-II) stage and the antenna reflector and aft solar panel are stowed. The PAMfl) 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., I in. in diameter and weighs 1,422 lb. at the beginning of life in 

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 spin table at the base spins the 

satellite to 55 rpm to provide gyroscopic stability. Four springs push the satellite into space; 45 minutes 

later, an onboard sequencer fires the McDonnell Douglas payload assist module. A Morton Thiokol Star 

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

TELSTAR 303 

The third in the Telstar 3 series of communications satellites will be deployed on flight day 3 during the 

ascending half of orbit 34. When combined with the single sideband Earth station equipment developed by 

AT&T Laboratories, each Telstar 3 satellite is capable of relaying nearly four times the number of 

simultaneous telephone calls commonly carried by satellites of the previous generation. Along with the 

company 5 other spacecraft, Telstar 303 will transmit AT&T's Skynet family of satellite services. 

The current AT&T Communications space network consists of two Telstar 3 satellites and two Comstar 

satellites leased from COMSAT. AT&T Communications -- the AT&T organization responsible for longdistance and international services -- launched the first of its Telstar 3 satellites in 1983 on a Delta rocket. 

The second rode into space during Discovery's maiden mission in August 1984. This particular satellite is 

scheduled to replace a Comstar satellite that is nearing the end of its service life. 

Designed for all types of domestic communications, the Telstar 3 satellites operate in the 6/4 GigaHertz Cband and serve the continental United States, Hawaii, Puerto Rico or Alaska, depending on exact orbital 

placement over the equator. Each satellite is able to relay hundreds of video teleconferences, 24 color 

television programs or billions of bits of high speed data and facsimile signals. The third Telstar 3 will be 

placed at 125 degrees w. longitude. It has a total of 24 working transponders, the equipment that receives 

and transmits communications signals, as well as six amplifiers held in reserve. 

In addition, improved batteries and solid state amplifiers will allow the Telstar 3 series of satellites to 

operate 3 years longer than the previous generation of satellites -~ for 10 rather than 7 years. 

The Telstar 3 series of satellites was designed by AT&T Bell Laboratories and built by the Hughes Aircraft 

Corp. using the Hughes 376 spacecraft. Each Telstar 3 satellite consists of two primary sections containing 

the communications units and the support systems, surrounded by two concentric cylinders. Once in space, 

the outer cylinder drops down about 6 ft. exposing the solar cells on the inner cylinder. With its antenna 

fully deployed in space, the satellite will have an overall length of 22.4 fit. and a diameter of 7.1 Et. The 

two cylinders are covered with 15,588 solar cells. When the satellite is in the sun's path, these cells, thin 

silicon chips, covert solar energy to electrical power to energize the satellite. When not operated by solar 

power, the Telstar 3 satellite uses nickel-cadmium, long-life batteries. 

The Telstar 3 spacecraft will use a PAM-fl) for transfer orbit insertion. Ground controllers at AT&T's 

Hawley, Pa., Satellite Management and control Facility will monitor the satellite until it reaches a selected 

apogee, or high point, at which time they will fire the onboard apogee kick motor to circularize the orbit at 

the geosynchronous altitude of 22,300 mi.

SPARTAN 1 

Spartan 1 is the first in a series of Shuttle launched, short duration free-flyers designed to extend the 

capabilities of sounding rocket class experiments. 

The primary mission of Spartan 1 is to perform medium resolution mapping of the X-Ray emission from 

extended sources and regions, specifically the hot (10,000 degrees C) gas pervading a large cluster of 

galaxies in the constellation Perseus and in the galactic center and Sco-X-2. in addition the X-Ray emission 

from the nuclear region of our own Milky way galaxy will be mapped. 

Spartan 1 is a rectangular structure, 126 by 42 by 48 in.; weight 2,223 lb. including 300 lb. of experiments. 

it will be deployed and retrieved using the Canadian-built robot arm. Total deployed time will be 

approximately 45 hours. 

The satellite is designed to accommodate experiments that require stellar or solar pointing and establishes 

its inertial reference using gyros and a cold gas Attitude Control System (ACS). The ACS, controlled by an 

internal micro-computer, will obtain an initial fix from the sun and two guide stars, Vega and Deneb, and 

then point the detectors at the desired celestial targets. 

All scientific and engineering data is recorded by an on-board tape recorder. No telemetry or command link 

is provided. Power is provided by internal batteries. When -Spartan is retrieved and the Shuttle returns, the 

recording tape will be removed and sent to the Goddard Space Plight Center where scientific data tapes 

will be generated. 

The Spartan 'family" of short duration satellites are designed to minimize operational interfaces with the 

orbiter and crew. The only interfaces are latching, release and berthing support, deployment and retrieval, 

and turn-on and checkout by the crew prior to deployment. By keeping the interfaces to a minimum, it is 

possible to operate the Spartan autonomously and minimize both demands on the orbiter timeline and 

impact on other experiments. 

Spartan 1 is built by the Attached Shuttle Payloads Project (ASP) at the Goddard Space Flight Center at a 

cost of approximately $3.5 million. 

The Spartan program manager is John A. Glaab, Office of Space Science and Applications, NASA 

Headquarters, Washington, D.C. ASP project manager at Goddard is Sterling Smith; David Shrewsberry is 

the mission manager. The project scientist is Dr. Ray Cruddace at the Naval Research Laboratory (NRL), 

Washington, D.C., and the principal investigator is Dr. Gilbert Fritz of NRL.

GETAWAY SPECIALS 

G-025 - Liquid Sloshing Behavior in Microgravity 

This experiment will examine the behavior of a liquid in a tank under microgravity conditions. It is 

representative of phenomena occurring in satellite tanks with liquid propellants. A reference fluid in a 

hemispherical model tank will be subjected to linear acceleration inputs of known levels and frequencies. 

The dynamic response of the tank liquid system will be recorded and analyzed. 

The results will validate and refine mathematical models describing the dynamic characteristics of tankfluid systems. This in turn will support the development of future spacecraft tanks, in particular the design 

of propellant management devices for surface tension tanks. 

The experiment was provided by MBB/ERNO, the prime contractor for the Spacelab. it is mounted on a 

Payload Support System (PASS) flight unit, identical to the system designed and developed by 

MBB/ERNO for the Federal German materials science project MAUS (in German, the acronym for 

materials science autonomous experiments), described below. PASS is a standardized structure, power 

supply and data processing unit. 

G-027 - Slipcasting Under Microgravity Conditions 

The process of slipcasting uses a ceramic slurry to form complicated shapes of hollow bodies. On Earth, 

this process is limited in applications because of gravitational influences on the dispersed particles in the 

slurry. sedimentation can be avoided only by the use of materials with equal densities or by the utilization 

of a stabilizing additive. However, the latter may be harmful to the desired properties of the slip-cast 

product. 

The goal of this experiment is to demonstrate with model materials that slipcasting is possible in 

microgravity, even with unstabilized suspensions using mixtures of powders with different density, grainsize and concentration. Ceramic and/or metal powders are homogeneously mixed in solid paraffin. Rods of 

these solid slurries are pressed into cartridges against the ends of porous ceramic rods mounted in the lower 

halves of the cartridges. 

During weightlessness, 13 samples of these solid slurries will be melted. Then slipcasting will be started by 

heating the lower parts of the cartridges. After cooling and solidification, the paraffin will preserve the 

slipcast layers as well as the residual slurries for later examination with respect to their structure and 

particle distribution. 

Mission 51-G will be the fifth flight of MAUS payloads, with 10 experiments having been carried into 

space since November 19B2. The project is managed by the German Aerospace Research Establishment 

(DFVLR) acting on behalf of the German Minister of Research and Technology (BMFT). The industrial 

prime contractor is MBB/ERNO. 

G-028 - Fundamental Studies in Manganese-Bismuth 

The objective of the experiment is to produce manganese-bismuth (MnBi) specimens with better magnetic 

properties than currently is possible under Earth gravity. other experiments have shown that during melting 

and solidification of alloys of the MnBi system in the absence of sedimentation and buoyancy and other 

forces promoting segregation, such as surface tension, likewise have no effect. Compared with the original 

materials there has been a distinct increase in the proportion of ferromagnetic MnBi. 

During this flight, MnBi, having interesting magnetic applications, will be prepared under microgravity 

conditions.

G-034 - Texas Student Experiments 

This payload features 12 different biological and physical science experiments designed by high school 

students from El Paso and Isleta, Texas. The effort was supported financially by the school districts 

involved and by businesses and other citizens in the area. A list of experiments, students and their schools 

follows; 

Growth of Lettuce Seeds David Bowden Hanks HS 

Barley Seed Germination Gisele Bryant Coronado HS 

Growth of Brine Shrimp Donald Cake Bassett Int. 

Germination of Turnip Seeds Pricillo Campos Irvin HS 

Liquid Laser Clay Casares Hanks HS 

Planaria Regeneration Monica Chavez Coronado HS 

Wicking of Fuels Kelly Foster Hanks ES 

Effectiveness of Antibiotics on Bacteria Karen Herman Morehead Tnt. 

Growth of Soil Mold Rebecca Lopez Bowie NH 

Crystallization in Zero-G Michael Moore Coronado NH 

Symbiotic Growth of Chlorella and Kefir in Microgravity Rudy Santini Isleta MS 

 Steven Walker Eastwood MS 

DRAM Chips John Thurston Canyon Hills 

A 13th experimenter, James Martinez, intends to make a post-flight examination of plant genetic structure 

with the returned biological materials. 

G-314 - Space Ultraviolet Radiation Experiment (SURE) 

This experiment has been designed to measure the natural radiation field in the upper atmosphere at 

extreme ultraviolet (EUV) wavelengths, between 50 and 100 nanometers. The hardware consists of a 

spectrometer which separates the wavelength band into two intervals of 128 discrete wavelengths. The 

radiation intensity at each wavelength is measured and stored on a tape recorder. 

The experiment instrument was developed in the Space Science Division at the Naval Research Laboratory 

(NRL) . it is the first of a series to be developed at NRL which ultimately will have the capability of 

observing “ionospheric weather.” It is envisioned that someday satellites will be stationed at high altitudes 

to provide global pictures of ionospheric weather conditions. Ionospheric storms, or the effects of such 

phenomena as solar flares or eruptions, could be monitored and their evolution followed. Effects on 

communication systems could be observed immediately anywhere in the world. 

The principal investigator of the SURE project is Dr. Robert Conway and the project engineer is Kenneth 

wolfram, both of NRL. Co-investigators are Drs. George Carruthers, Robert McCoy, Robert Meier, George 

Mount and Dianne Prinz, all of NRL. 

G-471 - Capillary Pump Loop (CPL) 

This experiment is the first of a thermal control system using capillary pumps. These pumps contain no 

moving parts but work on the principle of capillary action by which plants and trees transport water and 

nutrients from their roots to their leaves against the force of gravity. The purpose off the experiment is to 

demonstrate the thermal control capability of a capillary-pumped system under zero-gravity conditions for 

ultimate use in large scientific instruments, advanced orbiting 

spacecraft and Space Station components. 
Edited by Richard W. Orloff, 01/2001/Page 23

The CPL consists of two capillary-pumped evaporators with integral heaters, a fluid loop charged with 

ammonia, a condenser plate (heat sink) and various control electronics. Each pump contains a wick of 

porous material which is saturated with the working fluid. As heat is added, the fluid evaporates and travels 

to the condenser, thus transporting the heat at a nearly constant temperature from the heat source to its sink. 

The evaporation process produces the pressure gradient, or pumping action, that circulates the fluid. 

Principal investigator is Roy McIntosh of NASA's Goddard Space Flight Center, Greenbelt, Md.

AUTOMATED DIRECTIONAL SOLIDIFICATION FURNACE (ADSF) 

The Automated Directional Solidification Furnace (ADSF) will be carried into space for the first time on 

flight 51-G. Experiments to be carried out in the furnace are expected to demonstrate the capability of the 

ADHE equipment and provide preliminary scientific results on magnetic composites. Future missions are 

expected to demonstrate the feasibility of producing improved magnetic composite materials for 

commercial use. These materials could eventually lead to smaller, lighter, stronger and longer-lasting 

magnets for electrical motors used in aircraft and guidance systems, surgical instruments and transponders. 

In ground-based directional solidification, gravity-driven convection causes an undesirable stirring or 

mixing of the material; resulting in an unequal distribution of the composite material as it resolidifies. 

The furnace-is specially designed to melt a long, slim magnetic composite sample and then resolidify the 

molten metal material with a more uniform distribution of the composite material for further processing. 

Four furnace modules are included in the ADSF, each of which will process a single sample. The samples 

being used during the 51-G mission are a manganese and bismuth composite. They will be processed 

varying the speed of both the melt and resolidification. Material processed during the mission will then be 

compared with samples of the same metallic alloys processed in laboratories on Earth. 

The ADSF flight hardware is housed in three separate containers. It weighs about 250 lb. and occupies the 

space of five crew lockers in the orbiter middeck. Operation of the experiment is highly automated, 

requiring the crew only to initiate operation of each of the four furnaces. All of the ADSF flight hardware 

is reusable. 

The furnace was built by the General Electric Co. Principal investigator for the ADSF experiment is Dr. 

David Larson of the Grumman Aerospace Corp. Project manager is Fred Reeves and mission manager is 

Ed Valentine, Marshall Space Flight Center. The program is managed by Marshall for the Microgravity 

Science and Applications Division at NASA Headquarters Washington, D.C.

HIGH-PRECISION TRACKING EXPERIMENT 

The Strategic Defense Initiative Organization will fly the first of a series of technology development 

experiments aboard flight 51-G. The experiment, called a High-Precision Tracking Experiment, is designed 

to test the ability of a ground Laser Beam Director to accurately track an object in low-Earth orbit. 

The High-Precision Tracking Equipment payload consists of an 8-inch diameter retroreflector mounted in a 

cylindrical housing. when removed from its storage locker, the retroreflector assembly will be attached to 

the Shuttle's middeck side hatch window in order to receive and reflect a low-energy laser beam projected 

from a test facility located on the island of Maui, Hawaii. 

In addition to the High-Precision Tracking Equipment, the Strategic Defense Initiative organization has 

requested NASA support for experiments on two Shuttle flights a year beginning in 1987. Prior to that 

time, a variety of cabin and other experiments may be flown.
