CHALLENGER’S SIXTH FLIGHT HIGHLIGHTS EARTH SCIENCE 

Space Shuttle Challenger will return to space for the sixth time on the 41-G mission with a record-setting seven 

crew members and a full slate of scientific instruments and payloads. Launch is set for no earlier than Oct. 5, 1984, 

during a two-hour launch window that opens at 7:03 a.m. EDT, with landing at the Kennedy Space Center 

approximately 12:25 p.m. EDT on Oct. 13. 

The 41-G mission is the first space mission to include seven crew members, the first flight of a Canadian payload 

specialist, the first to include two women, the first spacewalk by an American woman, first crewman to fly a fourth 

Shuttle mission, first demonstration of a satellite refueling technique in space, and the first flight with a reentry 

profile crossing the eastern United States. 

The major payloads being flown on this mission include: NASA's Earth Radiation Budget Satellite (ERBS); 

NASA's Office of Space and Terrestrial Applications (OSTA-3) payload; Orbital Refueling System (ORS) 

experiment; and the Canadian National Research Council's scientific experiment packages known as CANEX. 

Flying again in the crew cabin will be the large film format IMAX motion picture camera and a hand-held device 

called Radiation Monitoring Equipment. The Aurora Photography Experiment and several battery powered devices 

to measure gamma radiation will be flying in the crew cabin for the first time. 

There will be eight Getaway Special canisters mounted in the cargo bay and the canisters will be activated by crew 

members at various times during the mission 

Leading the record-sized crew is veteran astronaut Robert L. Crippen, on his fourth Space Shuttle mission. Crippen 

was pilot of STS-l and commander of STS-7 and 41-C. The pilot is Jon A. McBride. Mission specialists are STS-7 

veteran Sally K. Ride and Kathryn D. Sullivan and David Leestma. The two payload specialists are Canadian Marc 

Garneau and oceanographer Paul D. Scully-Power. 

Challenger will be launched from Kennedy Space Center's complex 39A into a circular 218 statute mile orbit with 

an inclination to the equator of 57 degrees. 

Activities during the crew's first day in space, in addition to the normal systems tasks, will include activating the 

OSTA-3 and ORS payloads, checkout of the Canadian developed Remote Manipulator System (RMS), unpacking 

and preparing the IMAX camera, and starting checkout operations for deployment of ERRS. 

The ERBS spacecraft will be activated and given a systems checkout before being grappled by the RMS and lifted 

clear of the cargo bay. Suspended at the end of the arm, more checkouts will be performed and the solar cell panels, 

antennas and other appendages will be extended and locked. Once the appendages are extended and locked, the 

spacecraft can no longer be returned to the cargo bay. Approximately nine hours after liftoff, ERBS will be released. 

The orbiter will separate from the satellite and the ERBS will be free to maneuver to its operational altitude of 329 

statute miles. 

Flight day two activities will include the start of the Canadian experiments, visual performance tests for crew 

members, a change in orbital altitude and the first of four crew commanded transfers of fuel in the ORS. 

ORS is attached to the same support structure that holds the Large Format Camera and is designed to develop and 

demonstrate the equipment and techniques for refueling existing satellites on orbit. 

Four fuel transfers, controlled by the crew from within the crew cabin, will be performed during the mission in 

addition to a spacewalk designed to connect a servicing tool to valves which simulate existing satellites not 

originally designed for on-orbit refueling. 
Edited by Richard W. Orloff, 01/2001/Page 6

On flight day three, the crew will again change orbital altitudes, this time maneuvering to the optimum altitude for 

SIR-B radar observations. From this point on, ground controllers will command the SIR-B and Large Format 

Camera activities from payload operations centers. The flight crew meanwhile will also perform a second ORS fuel 

transfer by remote control, conduct additional visual performance tests and conduct miscellaneous experiments and 

tests. On the next day, more IMAX footage will be taken, the CANEX series will continue, and mission specialists 

Leestma and Sullivan will perform extensive checkouts of the Extravehicular Mobility Units or spacesuits and will 

also configure the cabin for the spacewalk scheduled for flight day five. 

The fifth flight day will see the first spacewalk by an American woman, a three-hour spacewalk in which mission 

specialists Leestma and Sullivan will install a valve assembly into simulated satellite propulsion plumbing. The 

simulated plumbing duplicates that of existing Landsat spacecraft, a prime contender for orbital refueling and 

refurbishment. 

Landsat and other existing satellites were not designed to be refueled and the installation of access valves is a 

prerequisite if such operations are to be undertaken. 

During the spacewalk, Leestma will be the lead installer, with Sullivan assisting. 

Flight day six and seven will feature tests of the valve system installed during the spacewalk with hydrazine being 

transferred through the valve section. More IMAX footage will be taken and visual performance tests and dosimeter 

readings will also be performed on these days. 

Flight day eight will include checkout of the Shuttle's flight control system, stowage of the SIR-B antenna and cabin 

gear and preparations for deorbit. 

On the final day, the crew will deactivate all payload systems, close the cargo bay doors and deorbit. The deorbit 

burn will take place over Australia during the final portion of orbit 132. The reentry track will pass across the 

United States along a path roughly from northwest Minnesota to southeast Georgia and on to a touchdown at 

Kennedy Space Center at about 12:25 p.m. EDT, on Oct. 13. .

OFFICE OF SPACE AND TERRESTRIAL APPLICATIONS (OSTA-3) 

OSTA-3 will carry a modified version of the Shuttle Imaging Radar (SIR-B) and three other flight-proven 

instruments; the Large Format Camera (LFC), Measurement of Air Pollution from Satellites (MAPS) and Feature 

Identification and Location Experiment (FILE). 

During OSTA-3 operations the orbiter's open cargo bay will face the Earth and the nose will point along the 

direction of flight. Visible data will be recorded on film and/or tape for targets on the Earth's surface directly below 

the orbiter. The radar antenna will be unfolded in orbit and used at various viewing angles. 

The objectives for OSTA-3 are to record photographic and radar images of the Earth's surface, to measure the 

global distribution of tropospheric carbon monoxide, and to attempt autonomous classification of scenes. The 

images will be used for making maps interpreting geological features and resource studies. 

SHUTTLE I MAGI NG RADAR- B ( SI R- B) 

The Shuttle Imaging Radar-B (SIR-B) experiment encompassing 44 different investigations in a wide range of 

disciplines, including archeology, geology, cartography, oceanography and vegetation studies. 

The imaging radar first flew as SIR-A on STS-2 in November 1981. SIR-B is an advanced version of the same radar 

system. The experiment was developed for the Office of Space Science and Applications by Dr. Charles Elachi and 

his team at NASA’s Jet Propulsion Laboratory, Pasadena, Calif. He also serves as the SIR-B principal investigator, 

in charge of a science team of 44 participants from 13 countries. 

Imaging radar produces photograph-like black-and-white images from data collected by transmitting millions of 

microwave radar pulses sequentially along a broad swath. Characteristics of the terrain alter the signals in different 

ways -- dry sand reflects a signal differently than a rocky surface. The signal returns to the radar, and the unique 

signature of each reflected pulse is recorded. These millions of radar snapshots are then reconstructed by computers 

to produce detailed imagery. 

One of the unique features of imaging radar sensors is their ability to acquire data over virtually any region at any 

time, regardless of weather or sunlight conditions. 

The SIR-B antenna consists of a 35-by-7-foot array of eight panels (SIR-A had seven panels). 

During launch and landing, the antenna will be folded in three pieces and stowed in the payload bay. On orbit, with 

the payload bay doors open, the SIR-B antenna will be deployed. It will remain deployed except during Shuttle 

maneuvers that require large altitude changes. SIR-B will collect 50 hours of data covering 18 million square miles 

of the Earth's surface. Radar operations and observations will be controlled by the SIR-B team from the payload 

operations control center at Johnson Space Center. 

The most significant new feature of the SIR subsystem is the antenna array tilt mechanism, which allows the 

antenna to be tilted to angles between 15 to 60 degrees. This will allow target areas to be viewed from several 

angles during successive orbital passes. In addition, the antenna can be specially tilted to image ground, water or 

vegetation surfaces that show greater detail when viewed from a steeper or shallower angle. At a command from the 

ground, the antenna will move from one orientation to another at the rate of about one degree per second. 

Analysis of SIR-A data collected over the eastern Sahara Desert revealed that the radar signals penetrated deposits 

of dry, windblown sand and were reflected by underlying geologic formations. The images revealed evidence of 

ancient river channels in Egypt and Sudan that are believed to be 5 to 40 million years old. 

Several experiments in desert regions were prompted by the SIR-A results in the Sahara. SIR-B will cover much of 

the deserts of Egypt and Sudan in search of other geologic formations and evidence of previous human habitation. 
Edited by Richard W. Orloff, 01/2001/Page 14

Other desert areas to be studied by SIR-B include regions in southwest Africa, India, the western coast of Peru, 

China, central Australia, Saudi Arabia and the Mojave in California. In addition, SIR-B data gathered in Saudi 

Arabia will be used for groundwater prospecting. 

The Swedish Island of Oland in the Baltic Sea, a major population center in the Middle Ages, will be viewed by 

SIR-B in an attempt to find ancient Nordic ruins. The island is extremely dry in summer months, and investigators 

hope the radar will pass through the thin layer of Earth covering the limestone plateau to reveal any ancient 

structures or roads. 

Other SIR-B investigations include: studies of tectonic features (East Africa, Canada, midwestern United States and 

Turkey); coastal landforms (The Netherlands); meteor impact craters (Canada); vegetation identification (North and 

South America, New Zealand, Australia and Europe); tropical deforestation (Brazil); damage to forests by acid rain 

(Germany); and crop monitoring (Japan, midwestern and western United States and Australia). 

Oceanographic studies will address: the propagation of extreme waves (Agulhas Current, southern Atlantic); 

internal waves (western and eastern Atlantic); sea Ice (South Polar Ocean); icebergs (Labrador coast); and oil spills 

(Pacific Ocean and North Sea). 

Data may be collected in one of three modes. Raw digital data produced at a rate of 46 megabits per second will be 

transmitted to a ground station at white Sands, N. M., via the 50 megabit-per-second data relay channel of the 

Tracking and Data Relay Satellite (TDRS). When the orbiter’s Ku-band antenna is out of view of the TDRS, SIR-B 

data will be recorded on a digital tape recorder in the aft flight deck of the Challenger. Recorded data will be 

transmitted to the ground via TDRS later in the mission. SIR-B also carries an optical film recorder that can be used 

to record raw data in analog form. 

LARGE FORMAT CAMERA 

The Large Format Camera (LFC) - first of its kind to orbit Earth - makes its debut this mission from a special 

support structure aboard Challenger. The camera is bigger, more stable, more precise and more technologically 

advanced in optics and electronics than its airborne predecessors. 

The 900-lb. space eye can produce 2,400 negatives from 70 pounds of film, including two types each of black and 

white and color. 

A unique lens combines the high resolution and wide field of view for precise stereo photography. Other camera 

elements are derived from instruments built for Apollo, Skylab and the Viking Mars landers. 

From 185 statute miles up, the camera's lens can capture scenes down to about 70 ft., the length of a single-family 

house, compared with 270 ft. taken by Landsat satellites, the main source of data for Earth resources. A single LFC 

frame can photograph an area larger than the state of Massachusetts. 

During the 41-G mission, the LFC will be calibrated with views of stars and the moon. It will carry out oblique 

photography and horizon scans, followed by two 2 1/2-hour hot and cold "soaks." 

Once calibrated the LFC will assist in worldwide exploration for oil and mineral resources, mapping and monitoring 

Earth’s environment. 

The LFC will be monitored by the orbiter's general purpose computer, with data sent to the Mission Operations 

Control Center at Johnson Space Center. The crew also can access the information and operate the camera. 

Principal investigator is Bernard H. Mollberg at the Johnson Space Center. The camera was produced for NASA by 

the Itek optical Systems Division of Litton Industries, Boston, Mass.

MEASUREMENT OF AI R POLLUTI ON FROM SATELLI TES ( MAPS) 

The 41-G mission will carry an experiment called Measurement of Air Pollution from Satellites (MAPS). Having 

flown previously on the Space Shuttle in November of 1981, the MAPS experiment will provide information as to 

what happens to industrial wastes after they enter the atmosphere, by measuring the distribution of carbon monoxide 

in the troposphere on a global scale. Subsequent flights of the MAPS experiment will be made to help determine the 

seasonal variation in this distribution. 

The equipment for MAPS consists of an electro-optical sensor and electronic module, a digital tape recorder, and an 

aerial camera. This equipment is coupled to a cold plate and mounted on the pallet shelf. 

Upon reaching Earth-viewing position, pallet power will be supplied and the MAPS instrument turned on. After a 

30-minute warm-up, the instrument is balanced and its gain is checked before it begins to acquire data. 

The instrument will continue to operate throughout the Earth-observation period, with balance and gain checks 

recurring every 12 hours upon commands sent from the principal investigator's team. 

The principal investigator for MAPS is Dr. Henry G. Reichle Jr. of NASA's Langley Research Center, Hampton, 

Va. 

FEATURE I DENTI FI CATI ON AND LOCATI ON EXPERI MENT ( FI LE) 

The Feature Identification and Location Experiment (FILE) is designed to help develop equipment which will make 

remote sensing instruments more efficient. Based on a simple classification algorithm, this is the first step toward 

the technology needed to select data at the sensing stage, thus reducing the data load and speeding data 

dissemination for Earth-observing missions. 

The FILE system consists of two charged-coupled detector (CCD) television cameras (one camera equipped with an 

optical filter for visual read, the other with near infrared), a logic unit, a buffer memory, two Lockheed Mark V tape 

recorders and two Hasselblad 70 mm cameras. Having flown previously on the OAST-l payload (STS-2) the FILE 

instrument will be the same except for the absence of the sun sensor. This was done to add greater flexibility to the 

OSTA-3 version for ground commands and alternative operation by the crew. 

The FILE instrument will be operated during sunlit intervals of the Earth-observing period by either ground 

command or crew activation. Principal Investigator is W. Eugene Sivertson with co-investigator R. G. Wilson both 

from NASA's Langley Research Center, Hampton, Va.

EARTH RADIATION BUDGET EXPERIMENT (ERBE) 

The Earth Radiation Budget Experiment (ERBE) is a three-satellite project that will accurately measure the amount 

of solar energy absorbed in different regions of Earth and the amount of thermal energy emitted back to space. 

Earth absorbs more energy in the tropics than it emits, and receives no solar radiation in the winter polar regions, 

though it continues to emit radiation. The difference in temperature causes the atmosphere and oceans to circulate 

and transfer energy, creating Earth's weather and climate. 

Earth's radiation budget and climate are changed by several processes: variations in the sun's output of radiation, 

veiling of Earth by volcanic dust, increases in atmospheric carbon dioxide from fossil fuel burning and other 

processes not yet fully understood. 

Investigators at NASA's Langley Research Center, working with other NASA centers, government agencies, 

universities and private industry, developed the Earth Radiation Budget Experiment to provide new information on 

radiation exchanges. 

The experiment consists of three sets of satellite-mounted instruments. One set is on the Earth Radiation Budget 

Satellite (ERBS), managed by NASA's Goddard Space Flight Center, that will be deployed during the 41-G 

mission. A second set will be on a National Oceanic and Atmospheric Administration (NOAA) satellite, NOAA-F, 

scheduled for launch into near-polar orbit in late 1984. The third set will be aboard NOAA-G, scheduled for launch 

in late 1985 or early 1986. 

The three-satellite ERBE system will measure thermal and solar radiation of the entire Earth at some time during 

each day, and most of the Earth at all times of day during every month. 

Each ERBE package consists of two instruments -- a Scanner and a Non-Scanner -- that use seven radiometer 

sensors to measure various intensities of radiant energy in the atmosphere and one sensor to measure solar intensity. 

ERBE’s primary goals are to determine, for at least one year: Earth's average monthly regional, zonal and global 

radiation budget; seasonal movement of energy from the tropics to the poles; and average daily variation in 

radiation on a 621-mile regional scale for each month. 

Secondary ERBE goals are to insure the accuracy and efficiency of the ERBE instruments and develop analysis 

techniques for a highly reliable, economical and long-term monitoring system, needed to supply information for 

climate monitoring and mathematical modeling of climate patterns. 

Earth's radiation budget has been studied for several years with instruments on sounding rockets, balloons and 

satellites, but the studies provided limited measurements, incomplete coverage and sporadic observations. 

NASA, the National Academy of Sciences and the National Science Foundation have developed a long-range 

climate research program to increase understanding of climate processes and determine climate predictability. 

NASA's program is managed by the Office of Space Science and Applications, NASA Headquarters, Washington, 

D.C. 

EARTH RADI ATI ON BUDGET SATELLI TE ( ERBS) 

The Earth Radiation Budget Satellite (ERBS) is one of three satellites in a program known as the Earth Radiation 

Budget Experiment Research Program. 

The 5,087-lb. spacecraft was built by Ball Aerospace Systems Division Boulder, Cob., which in collaboration with 

its subcontractor, Bendix Field Engineering Corp., Columbia, Md., also will conduct on-orbit operations under 

contract to NASA. 
Edited by Richard W. Orloff, 01/2001/Page 17

The spacecraft has three instruments -- the Earth Radiation Budget Experiment Scanner (ERBE-S); the Earth 

Radiation Budget Experiment Non-Scanner (ERBE-NS), both of which were built by TRW in Redondo Beach, 

Calif.; and the Stratospheric Aerosol and Gas Experiment II (SAGE II), built by Ball Aerospace. 

The spacecraft will be lifted out of the orbiter's payload bay by the Canadian-built Remote Manipulator System 

(RMS), a 50-ft. long mechanical arm. 

After separation from the RMS, the spacecraft's Orbit Adjust Propulsion System (GAPS) will be fired in a 

programmed sequence to raise the orbital altitude to 379 statute miles. Orbital inclination will be 57 degrees. 

ERBS is 15 ft. wide, 12.5 ft. high and 5.2 ft. long. 

The NASA Office of Space Science and Applications oversees the ERBE program; the Goddard Space Flight 

Center, Greenbelt, Md., is responsible for the overall project management. Langley has responsibility for the three 

instruments and science data reduction. Program manager is Dick Diller of NASA Headquarters, Project manager is 

Carl L. Wagner Jr. of Goddard. The instruments manager is Charles V. Woerner of Langley. 

I NSTRUMENTATI ON 

The ERBE instruments set will provide the measurements required to determine the Earth radiation budget on 

several spatial and temporal scales. The instrument measurements of the reflected short-wave and emitted longwave radiation from the Earth will be used to derive the solar-absorbed radiation and emitted thermal radiation 

monthly on regional, zonal and global scales. Data also will be analyzed for equator to pole energy transfer gradient, 

average diurnal variations, monthly and regionally and the total solar energy output. Furthermore, the data will be 

analyzed to ascertain instrument engineering integrity, calibration procedure effectiveness and the efficiency of 

sampling and analysis to determine changes in the radiation budget at the top of the atmosphere. 

ERBE NON- SCANNER ( ERBE- NS) 

The ERBE-NS has five sensors with cavity radiometer detectors. Four of the sensors are primarily nadir-pointed 

Earth-viewing sensors, with a fifth sensor used for solar viewing. Of the four nadir-pointed sensors, two view the 

entire Earth's disc from limb to limb. They are designated wide-field-of-view sensors 

The other two nadir-pointed sensors are designated medium-field-of-view. One of each pair of nadir-viewing 

channels measures the total radiation of the Earth, and the other measures the short-wave radiation. 

ERBE SCANNER ( ERBE- S) 

The ERBE-S has three sensors with radiometric thermistor bolometers (devices for measuring minute amounts of 

radiant energy). One is for short-wave measurements, one for long-wave measurements, and the third for total 

radiation measurements. The sensors are located within a continuously moving scanhead assembly which is oriented 

to perform cross-track scanning with a rapid retrace. A two-point inflight calibration is provided for each sensor. 

For one point, each detector views space during each scan for zero radiance. The second point is obtained periodically when the sun is in position for viewing or by inflight calibration. 

The ERBE-S measures 15.9 by 13,9 by 24.8 in. and weighs 70.8 lb. 

The ERBE-NS and the ERBE-S also will be launched aboard NOAA-F (1984) and NOAA-G (1985) as part of the 

ERBE Research Program.

STRATOSPHERI C AEROSOL AND GAS EXPERI MENT ( SAGE I I ) 

The Stratospheric Aerosol and Gas Experiment (SAGE II) instrument will monitor the vertical global distribution of 

aerosols and gases in the stratosphere by measuring the attenuation (reduction in intensity) of the sun's energy 

through Earth's atmosphere. The experiment was developed at NASA's Langley Research Center. 

The scientific objectives of the mission are to: (1) globally map vertical profiles of stratospheric aerosols, ozone, 

water vapor and nitrogen dioxide with one-kilometer vertical resolution from 80 degrees south to 80 degrees north 

latitude; (2) determine seasonal variations in the aerosols and gases to define a baseline for investigating natural and 

human effects on changes in climate and environmental quality; and (3) identify sources and sinks of the aerosols 

and gases and observe natural transient phenomena such as volcanic eruptions, tropical upwellings and dust storms. 

SAGE-II is 15.2 in. in diameter by 28.3 in. in length and weighs 65 lb. 

SAGE II will view about 15 sunrises and 15 sunsets each 24 hours, collecting solar attenuation profiles that will be 

mathematically reduced to atmospheric constituent concentration profiles. Each event occurs at a different latitude 

and longitude, and global coverage is repeated every three to four weeks. 

SAGE II data will be stored aboard the ERBS satellite and transmitted to a ground station each day. Instrument 

radiance data and spacecraft orbital parameters, synchronized to a common time base, will be provided to the SAGE 

II science team at the Langley Research Center for reduction and analysis. 

ERBS PAYLOAD OPERATI ONS CONTROL CENTER ( POCC) 

The Payload Operations Control Center (POCC) is the controlling facility for all spacecraft mission operations. The 

POCC contains all the processing resources, switching, control consoles and testing facilities to operate the mission 

assigned. All spacecraft operations will be conducted by Bendix Field Engineering Corp. personnel at the Goddard 

Space Flight Center, under the direction of Ball Aerospace Systems Division.

ORBITAL REFUELING SYSTEM (ORS) 

The. Orbital Refueling System experiment is a demonstration of Shuttle-human-tended capabilities to refuel already 

orbiting satellites once their self-contained thruster systems have depleted fuel reserves. This demonstration is a 

precursor to actual Shuttle refueling missions for satellites. 

The ORS has been designed to deliver about 550 lb. of fuel to a retrieved satellite. The system, developed by the 

Engineering Directorate at Johnson Space Center, will be tested on 41-G in various stages leading to a full 

hydrazine transfer between two different tanks on the ORS support structure. 

For the final fuel transfer stage, mission specialists David Leestma and Kathryn Sullivan will don their spacesuits 

and proceed to the aft end of the payload bay where the ORS equipment is mounted on an MPESS (Mission 

Peculiar Experiment Support Structure) along with the Large Format Camera. There the crewmembers will open the 

tool kit and remove the hydrazine servicing. tool --which will already be hooked up to the fuel supply tank. The 

crewmembers will connect it to the ground fill panel of a simulated satellite panel, thus completing the fuel supply 

link. After pressure checking the hookup, the crewmembers will return to the cabin. 

The actual transfer of the hydrazine, which is a very toxic and corrosive material, will be controlled from the aft 

flight deck experiment control panels. The ORS is equipped with sensors which provide pressure and temperature 

values and switch and valve positions.

CANADIAN EXPERIMENTS (CANEX) 

Marc Garneau, the Canadian payload specialist, will conduct 10 experiments for the National Research Council 

(NRC) of Canada. The experiments fall into three categories: space technology, space science and life sciences. 

NRC Spac e Vi s i on Sys t e m 

The National Research Council Space Vision System is a state-of-the-art development in robotic technology being 

designed to work with the Space Shuttle and Canadarm, the remote manipulator system that Canada contributed to 

the United States Space Shuttle program, The same technology also has many potential applications in the industrial 

community. 

The system is being designed to give more precise guidance information to make it easier for astronauts to 

approach, capture and then berth large satellites or to assemble other structures in space under the dramatically 

changing lighting conditions which can occur rapidly in space. 

During their tests, Marc Garneau will assist in the operation of the orbiter's closed-circuit television cameras and 

make video recordings of stationary and moving test targets under a range of lighting conditions and distances. 

The purpose of the tests is to aid development of the NRC Space Vision System to be used in space for rendezvous, 

inspection and assembly tasks and to be flown in orbit for the first time in 1986. 

Advanc e d Compos i t e Mat e r i al s Expos ur e 

Spacecraft structures and mechanisms have begun to make use of strong, lightweight composite materials of 

graphite fiber and epoxy compounds. There is some evidence that these materials deteriorate in the space 

environment through exposure to atomic oxygen at high velocities (eight kilometers a second). 

For this experiment, a number of samples of different materials have been attached to the Remote Manipulator Arm 

to see what deterioration, if any, occurs during a short-duration flight, The arm will be extended so that the samples 

face the direction of flight for 36 hours. Analysis will be conducted after the flight when the samples have been 

returned to Canada. 

Me as ur e me nt s Us i ng a Sunphot ome t e r 

The Canadian-made Sunphotometer is a hand-held instrument which is pointed at the sun to obtain readings of solar 

radiation at several wavelengths in the visible and the near-infrared region of the spectrum. This instrument is used 

by the Canadian Atmospheric Environment Service to measure local atmospheric constituents and to monitor acidic 

haze. 

At mos phe r i c Mi s s i on and Shut t l e Gl ow Me as ur e me nt s 

During space flight, some surfaces of the orbiter develop a faintly visible reddish glow which could affect optical 

instruments of payloads. 

The causes and characteristics of the glow are not fully understood; but, under suitable conditions, it may be photographed. This experiment involves the use of very high-resolution optical filters and an image intensifier to obtain 

photographs which can be analyzed to identify the reactions which produce these emissions.

Spac e Adapt at i on Syndr ome Expe r i me nt St udi e s 

Marc Garneau will conduct a set of experiments to isolate and measure several of the key adaptation processes 

occurring during the first days in space. 

The experiments located in the mid-deck will examine vestibulo-ocular reflex, sensory function in limbs, 

proprioceptive illusions, awareness of external objects, space motion sickness and taste in space.

RADIATION MONITORING EQUIPMENT (RME) 

Radiation Monitoring Equipment (RME) will be used to actively measure any gamma radiation exposure to the 

crew in the orbiter cabin. The experiment consists of a handheld radiation monitor (Gamma and Electron 

Dosimeter) and two pocket RME meters (Neutron and Proton Dosimeter). The two meters are self-contained and 

each includes a 9-volt alkaline battery. Data will be collected several times throughout the mission, with the meters 

being operated by the crew. 

THERMOLUMINESCENT DOSIMETER (TLD) 

The Thermoluminescent Dosimeter (TLD) is a small portable dosimetry system developed by the Central Research 

Institute for Physics in Budapest, Hungary, and will be carried in a cabin locker. It is being flown to obtain cosmic 

radiation doses during space flight for comparison with the presently used dosimetry systems. 

IMAX

Located in the mid-deck will be an IMAX motion picture camera, making the third and final scheduled trip into 

space aboard the Shuttle. Footage from the Shuttle flights will be assembled into a film called "The Dream Is 

Alive." 

The IMAX high-fidelity motion picture system uses a large 70 mm film frame which, because of its size, improves 

picture quality. IMAX films are displayed on a screen that is nine times larger than a conventional screen. 

The IMAX camera is part of a joint project among NASA, the National Air and Space Museum, IMAX Systems 

Corp. of Toronto, Canada, and the Lockheed Corp.
