This is the fourth of nine planned missions to Mir between 1995 and 1998 and the first exchange of astronauts. Astronaut Shannon W. Lucid, who has been on Mir since late March, will be replaced on Mir by astronaut John E. Blaha. Blaha will spend more than four months on Mir. He will return to Earth on Space Shuttle Mission STS-81, scheduled for launch in January 1997. STS-79 is the second Shuttle-Mir mission to carry a SPACEHAB module on board, and the first to carry a double module. The forward portion of the double module will house experiments conducted by the crew before, during and after Atlantis is docked to the Russian space station. The aft portion of the double module primarily houses the logistics equipment to be transferred to the Russian space station. Logistics include food, clothing, experiment supplies, and spare equipment for Mir. The STS-79 crew will be commanded by William F. Readdy, who will be making his third Shuttle flight. The pilot, Terrence W. Wilcutt, will be making his second. There are four mission specialists assigned to this mission. Jay Apt, serving as Mission Specialist-1, is making his fourth Shuttle flight. Also making his fourth flight and serving as Mission Specialist-2 is Thomas D. Akers. Carl E. Walz, flying on his third flight, is serving as Mission Specialist-3. Blaha, a veteran of four missions, will serve as Mission Specialist-4 from launch to docking. After the on-orbit crew exchange, Lucid will serve as Mission Specialist-4 through landing. Atlantis is targeted for an early morning launch in mid-September from Kennedy Space Center's Launch Complex 39-A. The actual launch time may vary by a few minutes based on calculations of Mir's precise location in space at the time of liftoff due to Shuttle rendezvous phasing requirements. The STS-79 mission is scheduled to last nine days, five hours. Atlantis' rendezvous and docking with the Mir actually begins with the precisely timed launch setting the Orbiter on a course for rendezvous with the Mir station. Over the next three days, periodic firings of Atlantis' small thruster engines will gradually bring the Shuttle within closer proximity to the Mir. The STS-79 mission is part of the NASA/Mir program which is now in Phase 1B, consisting of nine Shuttle- Mir dockings and seven long-duration flights of U.S. astronauts aboard the Russian space station between early 1996 and late 1998. The U.S. astronauts will launch and land on a Shuttle and serve as a Mir crew member while the Mir cosmonauts use their traditional Soyuz vehicle for launch and landing. This series of missions will expand U.S. research on Mir by providing resupply materials for experiments to be performed aboard the station as well as returning experimental samples and data to Earth. The current Mir 21 mission began when the cosmonaut crew launched on February 21, 1996, in a Soyuz vehicle and docked with the Mir two days later. Dr. Shannon Lucid joined the Mir 21 crew with the March 1996, docking of STS-76. Lucid will complete her stay on the Mir and return with the STS-79 crew. On August 19, the Mir 21 crew was joined by the crew of Mir 22. The Mir 22 crew will remain on Mir after the Mir 21 crew returns to Earth in September. The STS-79 mission also will include several experiments in the fields of advanced technology, Earth sciences, fundamental biology, human life sciences, microgravity, and space sciences. Data also will supply insight for the planning and development of the International Space Station, Earth-based sciences of human and biological processes, and the advancement of commercial technology. STS-79 will mark the largest transfer of logistics to and from the Mir space station to date. During the docked phase, 4,600 pounds of water, food, and other resupply items along with research hardware and equipment will be transferred from Atlantis to the Mir. Atlantis will return to Earth with 2,200 pounds of Russian, European Space Agency, and U.S. science samples and hardware. STS-79 will mark the first transfer of powered scientific apparatus to Mir as five different experiments are powered down on the Shuttle and rapidly transferred to Mir. STS-79 will be the 17th flight of Atlantis and the 79th mission flown since the start of the Space Shuttle program in April 1981. -end- 2.0 Media Services Information NASA Television Transmission NASA Television is available through the Spacenet-2 satellite system.

Abort modes for STS-79 include: Abort-To-Orbit (ATO) -- Partial loss of main engine thrust late enough to permit reaching a minimal 105-nautical mile orbit with the orbital maneuvering system engines. Abort-Once-Around (AOA) -- Earlier main engine shutdown with the capability to allow one orbit of the Earth before landing at the Kennedy Space Center, FL. Transoceanic Abort Landing (TAL) -- Loss of one or more main engines midway through powered flight would force a landing at either Ben Guerir, Morocco; or Moron, Spain. Return-To-Launch-Site (RTLS) -- Early shutdown of one or more engines, and without enough energy to reach a TAL site, would result in a pitch around and thrust back toward Kennedy until within gliding distance of the Shuttle Landing Facility. 9.0 Mir Rendezvous and Docking Atlantis' rendezvous and docking with the Russian space station Mir actually begins with the precisely timed launch of the Shuttle on a course for the Mir, and, over the next two days, periodic small engine firings that will gradually bring Atlantis to a point eight nautical miles behind Mir on docking day, the starting point for a final approach to the station. Mir Rendezvous -- Flight Day 3 About two hours before the scheduled docking time on Flight Day Three of the mission, Atlantis will reach a point about eight nautical miles behind the Mir space station and conduct a Terminal Phase Initiation burn, beginning the final phase of the rendezvous. Atlantis will close the final eight nautical miles to Mir during the next orbit. As Atlantis approaches, the Shuttle's rendezvous radar system will begin tracking Mir and providing range and closing rate information to Atlantis. Atlantis' crew also will begin air-to-air communications with the Mir crew using a VHF radio. As Atlantis reaches close proximity to Mir, the Trajectory Control Sensor, a laser ranging device mounted in the payload bay, will supplement the Shuttle's onboard navigation information by supplying additional data on the range and closing rate. As Atlantis closes in on the Mir, the Shuttle will have the opportunity for four small successive engine firings to fine-tune its approach using its onboard navigation information. Identical to the three prior Mir dockings, Atlantis will aim for a point directly below Mir, along the Earth radius vector (R-Bar), an imaginary line drawn between the Mir center of gravity and the center of Earth. Approaching along the R-Bar, from directly underneath the Mir, allows natural forces to brake Atlantis' approach more so than would occur along a standard Shuttle approach from directly in front of Mir. During this approach, the crew will begin using a handheld laser ranging device to supplement distance and closing rate measurements made by Shuttle navigational equipment. The manual phase of the rendezvous will begin just as Atlantis reaches a point about a half-mile below Mir. Commander Bill Readdy will fly the Shuttle using the aft flight deck controls as Atlantis begins moving up toward Mir. Because of the approach from underneath Mir, Readdy will have to perform very few braking firings. However, if such firings are required, the Shuttle's jets will be used in a mode called "Low-Z," a technique that uses slightly offset jets on Atlantis' nose and tail to slow the spacecraft rather than firing jets pointed directly at Mir. This technique avoids contamination of the space station and its solar arrays by exhaust from the Shuttle steering jets. Readdy will center Atlantis' docking mechanism with the Docking Module mechanism on Mir, continually refining this alignment as he approaches within 300 feet of the station. At a distance of about 30 feet from docking, Readdy will stop Atlantis and keep station momentarily to adjust the docking mechanism alignment, if necessary. At that time, a final go or no-go decision to proceed with the docking will be made by flight control teams in both Houston and Moscow. When Atlantis proceeds with docking, the Shuttle crew will use ship-to-ship communications with Mir to inform the Mir crew of the Shuttle's status and to keep them updated on major events, including confirmation of contact, capture and the conclusion of damping. Damping, the halt of any relative motion between the two spacecraft after docking, is performed by shock absorber-type springs within the docking device. Mission Specialist Carl Walz will oversee the operation of the Orbiter Docking System aboard Atlantis. Undocking, Separation and Mir Fly-Around Once Atlantis is ready to undock from Mir, the initial separation will be performed by springs that will gently push the Shuttle away from the docking module. Both the Mir and Atlantis will be in a mode called "free drift" during the undocking, a mode that has the steering jets of each spacecraft shut off to avoid any inadvertent firings. Once the docking mechanism's springs have pushed Atlantis away to a distance of about two feet from Mir, where the docking devices will be clear of one another, Readdy will turn Atlantis' steering jets back on. Immediately, he will fire the Shuttle's jets in the Low-Z mode to begin slowly moving away from Mir. Atlantis will continue away from Mir to a distance of about 600 feet, where Readdy and Pilot Terry Wilcutt will begin a flyaround of the station. Atlantis will circle Mir twice before firing its jets again to depart. During this flyaround the crew will perform documentary photography of the Mir space station, including the newly arrived "Priroda" science module, using still and video cameras as well as the IMAX large format movie camera. Logistics Transfers STS-79 will mark the first flight with a double SPACEHAB module, increasing the amount of logistics the Shuttle can carry to the Mir space station. In addition to the U.S. astronaut exchange, the STS-79 crew will transfer over 4,600 pounds of food, water, clothing, personal hygiene supplies, replacement Mir hardware components, and U.S. science experiments and supplies to the Mir, including five powered experiments (experiments requiring electrical power on the Shuttle and immediately on Mir.) The Atlantis crew will simultaneously receive over 2,100 pounds of Russian hardware, empty food and water containers, ESA return science items, and U.S. science hardware, data and specimens from Shannon Lucid's science gathering activities during her stay on Mir. This is the largest Shuttle transfer of logistics to and from the Mir to date. 10.0 Shuttle/Mir Science The NASA/Mir program is now into the Phase 1B portion, which consists of nine Shuttle-Mir dockings and seven long- duration flights of U.S. astronauts aboard the Russian space station between early 1996 and late 1998. The U.S. astronauts will launch and land on a Shuttle and serve as a Mir crewmember for flight durations ranging from 127 to 158 days, while the Mir cosmonauts stay approximately 180 days and use their traditional Soyuz vehicle for launch and landing. This series of missions will expand U.S. research on Mir by providing resupply materials for experiments to be performed aboard Mir as well as returning experimental samples and data to Earth. The Mir 21 mission began when the crew launched on February 21, 1996, in a Soyuz vehicle and docked with the Mir two days later. Dr. Shannon Lucid joined the Mir 21 crew with the March 24, 1996, docking of STS-76. The return of STS-79 will conclude a mission of experiments in the fields of advanced technology, Earth sciences, fundamental biology, human life sciences, microgravity, and space sciences. Data also will supply insight for the planning and development of the International Space Station (ISS), Earth-based sciences of human and biological processes, and the advancement of commercial technology. Science Overview As scientists learn more about the effects of the space environment, they continue to develop questions from the fields of human life sciences, behavioral sciences, fundamental biology, biotechnology, material sciences, and spacecraft structural and environmental dynamics. Valuable scientific information regarding these subjects will be returned from the Shuttle Mir Science Program disciplines of advanced technology, Earth sciences, fundamental biology, human life sciences, ISS, microgravity and space sciences. These investigations will provide valuable information about space flight and long term exposure to the microgravity environment. This knowledge will assist researchers in developing future space stations, science programs, procedures for those facilities, and advance the knowledge base of these areas to the benefit of all people on Earth. The commercial initiated research and technology from the advanced technology discipline will evaluate new technologies and techniques using the Mir space station as a test bed. An increased understanding of the characteristics of superconductors, protein crystal growth, and the development of biological and chemical systems through fluid processing in reduced gravity can lead to an enhanced technological base for implementation on the International Space Station and commercial processing here on Earth. Earth sciences research in ocean biochemistry, land surface hydrology, meteorology, and atmospheric physics and chemistry also will be performed. Observation and documentation of transient natural and human-induced changes will be accomplished with the use of passive microwave radiometers, a visible region spectrometer, a side-looking radar, and hand-held photography. Earth orbit will allow for documentation of atmospheric conditions, ecological and unpredictable events, and seasonal changes over long time periods. Fundamental biology research continues developmental investigations that study the effects of the space environment on the biological systems of plants. Prolonged exposure to microgravity provides an ideal opportunity to determine the role gravity has on cell regulation and how this affects development and growth. Investigations under this discipline will also characterize the internal radiation environment of the Mir space station. Human life sciences research consists of investigations that focus on the crewmember's adaptation to weightlessness in terms of skeletal muscle and bone changes, psychological interactions, immune system function, and metabolism. In addition, environmental factors such as water quality, air quality, surface assessment for microbes, and crew microbiology will be assessed. These ambitious investigations will continue the characterization of the integrated human responses to a prolonged presence in space. The International Space Station risk mitigation discipline consists of several technology demonstrations associated with human factors and maintenance of crew health and safety aboard the space station. In order to improve the design and operation of the International Space Station, information is gathered to fully evaluate the Mir interior and exterior environments. This discipline includes investigations of radio interference, crew force impacts to structures, particle impact on the station, docked configuration stability, water microbiological monitoring and inventory management. Microgravity research will advance scientific understanding through research in biotechnology, fluid physics, combustion science, and materials science. The ambient acceleration and vibration environment of Mir will be characterized to support future research programs. Space science research continues with the externally mounted Mir Sample Return Experiment (MSRE) and Particle Impact Experiment (PIE) payloads. These experiments continue to collect interstellar and interplanetary space particles to further our understanding of the origin and evolution of planetary systems and life on Earth. Most of the Mir 22/NASA 3 research will be conducted on the Mir; however, Shuttle-based experiments are conducted in the middeck and SPACEHAB modules of STS-79 and STS-81. Fundamental Biology The microgravity environment on a long duration mission provides an ideal opportunity to determine the role gravity plays in molecular mechanisms at a cellular level and in regulatory and sensory mechanisms, and how this affects development and fundamental biological growth. Fundamental biology is also responsible for characterizing the radiation of the Mir environment and determining how it may impact station-based science. Environmental Radiation Measurements Exposure of crew, equipment, and experiments to the ambient space radiation environment in low Earth orbit poses one of the most significant problems to long term space habitation. As part of the collaborative NASA/Mir Science program, a series of measurements are being compiled of the ionizing radiation levels aboard Mir. During the mission, radiation will be measured in six separate locations throughout the Mir using a variety of passive radiation detectors. This experiment will continue on later missions, where measurements will be used to map the ionizing radiation environment of Mir. These measurements will yield detailed information on spacecraft shielding in the 51.6-degree-orbit of the Mir. Comparisons will be made with predictions from space environment and radiation transport models. Greenhouse-Integrated Plant Experiments The microgravity environment of the Mir space station provides researchers an outstanding opportunity to study the effects of gravity on plants, specifically dwarf wheat. The greenhouse experiment determines the effects of space flight on plant growth, reproduction, metabolism, and production. By studying the chemical, biochemical, and structural changes in plant tissues, researchers hope to understand how processes such as photosynthesis, respiration, transpiration, stomatal conductance, and water use are affected by the space station environment. This study is an important area of research, due to the fact that plants could eventually be a major contributor to life support systems for space flight. Plants produce oxygen and food, while eliminating carbon dioxide and excess humidity from the environment. These functions are vital for sustaining life in a closed environment such as the Mir or the International Space Station. Wheat is planted and grown in the "Svet," a Russian/Slovakian developed plant growth facility, where photosynthesis, transpiration, and the physiological state of the plants are monitored. The plants are observed daily, and photographs and video images are taken. Samples are also collected at certain developmental stages, fixed or dried, and returned to Earth for analysis. Human Life Sciences The task of safely keeping men and women in space for long durations, whether they are doing research in Earth orbit or exploring other planets in our solar system, requires continued improvement in our understanding of the effects of space flight factors on the ways humans live and work. The Human Life Sciences (HLS) project has a set of investigations planned for the Mir 22/NASA 3 mission to determine how the body adapts to weightlessness and other space flight factors, including the psychological and microbiological aspects of a confined environment and how they readapt to Earth's gravitational forces. The results of these investigations will guide the development of ways to minimize any negative effects so that crewmembers can remain healthy and efficient during long flights, as well as after their return to Earth. Assessment of Humoral Immune Function During Long Duration Space Flight Experiments concerned with the effects of space flight on the human immune system are important to protect the health of long duration crews. The human immune system involves both humoral (blood-borne) and cell-mediated responses to foreign substances known as antigens. Humoral responses include the production of antibodies, which can be measured in samples of saliva and serum (blood component). The cell-mediated response, which involves specialized white blood cells, appears to be suppressed during long duration space missions. Preflight, a baseline saliva and blood sample is collected. While on Mir, the crew is administered a subcutaneous antigen injection. In flight and postflight, follow-up blood and saliva samples are collected to measure the white blood cell activation response to the antigen. 11.0 Commercial Payloads Two commercial payloads will be transferred to Mir on STS-79 and will be retrieved by STS-81 some four months later: POWERED TRANSFER ITEMS Biotechnology System (BTS) The Bioreactor rotating wall vessel developed at the Space Cell Biology and Biotechnology Center at NASA's Johnson Space Center is the first of a series of long-duration cell culture experiments. BTS will study the three-dimensional growth of cartilage cells during its 147-day mission. Cartilage is the material that makes up the joints in the human body. The bioreactor enables the growth of mature cartilage from a small number of starting cells. This level of maturity is rarely achieved by other culture methods. Dr. Lisa Freed of MIT is using BTS to study cartilage so that cartilage cells may be engineered for replacement and transplantation. STS-79 astronauts will activate BTS and sample the culture to ensure it is viable and sterile before transferring it to Mir. Aboard Mir, John Blaha will take weekly samples of the culture, and return the entire experiment on STS-81. Material in Devices as Superconductors (MIDAS) The MIDAS experiment, developed at NASA's Langley Research Center, Hampton, VA, will fly into orbit on STS-79 and be transferred over to the Russian Mir space station for approximately four months. While on the Mir, MIDAS will measure the electrical properties of high temperature superconductor (HTS) materials during extended space flight and compile the results in a database for commercial use. HTS materials may be used in a variety of device applications to reduce power requirements and thermal losses. In addition to the development of a database, the MIDAS experiment will demonstrate the development of a manufacturing process using integrated superconductor and conventional microelectronics. There have been no previous flights which characterize HTS material in spaceflight at cryogenic temperatures. Sample boards are provided by the Eaton Company (USA), the Moscow Institute of Electronic Equipment (Russia), and the Langley Research Center. Commercial Generic Bioprocessing Apparatus (CGBA) The CGBA hardware has been used extensively on short duration Shuttle missions to house a great variety of biotechnology experiments of interest to commercial product development. There are many biotechnology processes which require much longer periods of time than a Shuttle mission can provide. For this reason, the commercial affiliates of BioServe Space Technologies, a NASA Commercial Space Center, are eager to take advantage of the long duration mission which the Shuttle/MIR program provides. Among the experiments carried by the CGBA to Mir will be small, self -contained aquatic ecosystems -- complete with both plants and animals -- developed by Paragon Space Sciences of Tucson, AZ. A leading American pharmaceutical company will conduct experiments to determine the secondary metabolite production in plant tissue. In addition, a leading biotechnology concern is taking advantage of this long duration mission to conduct crystallization experiments involving proteins and oligonucleotides. In addition, three experiments will make a round-trip voyage aboard Atlantis itself: Extreme Temperature Translation Furnace (ETTF) The ETTF, which will be integrated into the SPACEHAB module, is a new furnace design allowing space-based processing up to 1,600 degrees Centigrade and above. ETTF was developed by McDonnell Douglas Aerospace, Huntsville, AL, and the Consortium for Materials Development in Space at the University of Alabama-Huntsville (UAH), a NASA Commercial Space Center. ETTF is designed to investigate how flaws form in cast and sintered metals. Studying the basic thermodynamics and behavior of pores and metal grains will allow metallurgists to make stronger machine tools on Earth. The furnace is integrated into a SPACEHAB single rack to demonstrate the facility's on-orbit capabilities. Major ETTF elements include the furnace assembly, a flight computer for experimental processing, a power and switching assembly for the furnace and an experiment power switching unit for control of the water cooling system. A 3-DMA gravitational measurement and recording system is embedded in the ETTF design to allow the experimenter to correlate G-loads with scientific results. The ETTF will process four ampoules containing sintered metal compositions as well as iron. Furnace melts will be made at 1,000 degrees Centigrade, 1150C, 1375-1400C and 1540 to 1600C. Teledyne Advanced Materials Systems is a partner for the sintered samples. Commercial Protein Crystal Growth (CPCG) Experiments STS-79 will include the 31st Shuttle flight of a Protein Crystal Growth payload managed by the Center for Macromolecular Crystallography, a NASA Commercial Center for the Development of Space based at the University of Alabama at Birmingham. The complement of CPCG experiments aboard this mission is comprised of 128 individual samples involving twelve different proteins. The samples will be processed at 22 degrees Centigrade using the newly developed Commercial Vapor Diffusion Apparatus (CVDA). The goal of these experiments is to produce large, well-ordered protein crystals in the microgravity environment from very small volumes of protein solutions. These crystals will be used for X-ray diffraction studies to determine the three- dimensional structures of the individual proteins singly, and as they are bonded to other key molecules. The CVDA hardware consists of 32 "banks" of sample holders, each containing four separate experiment chambers. This hardware is an adaptation of the most common laboratory method (vapor diffusion) for growing protein crystals. Each chamber contains a double-barreled syringe which is loaded with protein and precipitant, prior to launch. The bottom of the chamber is fitted with a cylinder of polymer wicking material which holds a more concentrated reservoir solution. After orbit is attained, a crew member activates the experiments by using a gauged mechanism to extrude the solution from the syringe barrels to form a protein droplet on each syringe tip. The droplet becomes more concentrated as water diffuses from it, through the vapor phase, to the more concentrated reservoir solution captured in the wicking material. As equilibrium is approached, protein crystals grow slowly in the protein droplet. The samples on this mission flown for commercial development purposes include a protein responsible for causing some types of asthma and other allergic reactions. Another is an enzyme that is important for the activation of the "complement system." This system of enzymes protects humans by killing microorganisms and infected cells. Mechanics of Granular Materials This experiment seeks to develop a quantitative scientific understanding of the behavior of cohesionless granular materials in dry and saturated states at very low confining pressures and effective stresses. Cohesionless granular materials are unlike other engineering materials since their strength and stiffness properties derive entirely from friction and dilatancy. Dilatency is the change of volume associated with the application of shear stresses. The strength and stiffness of these materials are usually several orders of magnitude lower than cementious composites. Granular material properties depend on confinement. Investigators expect to see higher axial loads for a given axial displacement in microgravity. This data could help scientists to understand the behavior of the Earth's surface during earthquakes and landslides. The MGM experiment was developed by Sandia National Laboratories, in cooperation with the University of Colorado and the Marshall Space Flight Center. Risk Mitigation Experiments Several experiments are planned during STS-79 to obtain data that will reduce the development risk for the International Space Station. RME 1302: Mir Electric Field Characterization The radio frequency interference (RFI) environment seen by the Shuttle is of increasing concern due to new ground-based transmitters for communications and radar applications. In addition, the 52 degree inclination of the International Space Station (ISS) orbit will expose ISS and the Shuttle to larger radio-frequency radiation levels due to longer travel over populated areas. This experiment seeks to collect data on the internal and external RFI in the 40 Mhz to 18 Ghz frequency band. Part one of this experiment will be conducted in the Shuttle cabin only. Part two will be conducted in the Priroda module of the Mir station. Data will assist designers in the selection of frequency bands for radio-frequency components of ISS and its supporting systems. RME 1312: Real-time Radiation Monitoring Device (RRMD) RRMD measures the elemental composition and energy spectra of cosmic radiation in real-time. It also provides information on the effect of radiation on biological samples. The detector unit contains a Linear Energy Transfer Spectrometer. Biological samples in the dosimeters are dry E-Coli and plasmid DNA. Biological samples in the biospecimen box are E- Coli and D. radiodurans mixed with a liquid nutrient. The investigators are interested in the ability of bacteria to repair any radiation-damaged DNA. RRMD was developed by NASDA and Mitsubishi Heavy Industries, Ltd. of Japan. RME 1313: Active Rack Isolation System (ARIS) The Active Rack Isolation System is designed to isolate certain classes of science experiments from major mechanical disturbances that might be found on the International Space Station. Active isolation augments passive isolation, adding apparent mass and damping, thus canceling accelerations. Specifically, ARIS is expected to isolate payloads from low frequency vibrations. The objective of the ARIS flight experiment is to expose the system to accelerations due to the Space Shuttle and also due to the Shuttle/Mir orbital complex, which will provide a low frequency vibration environment similar to that anticipated for the International Space Station. ARIS isolation performance cannot be proven by ground testing, hence the flight test on STS-79 was proposed to characterize ARIS performance, measuring its isolation capabilities from .003 to 300 Hertz. The ARIS rack is being developed by the Boeing Defense and Space Group in Seattle, WA. The ARIS hardware is integrated into an ISS International Standard Payload Rack (ISPR). The ISPR was then integrated into the SPACEHAB, placed in a double rack enclosure on the starboard side of SPACEHAB. ARIS weighs approximately 700 pounds, which includes 350 pounds of Russian logistics as ballast. During the flight, periods without jet firings as well as specific jet firing occasions will be required to evaluate ARIS performance. RME 1319: Inventory Management System (IMS) This experiment seeks to determine the utility of using a bar code reader to keep track of items transferred from Shuttle to Mir and from Mir to Shuttle. Bar code tags will be attached to selected transfer items. Results of this experiment will help in determining the type of IMS required for the International Space Station. The IMS experiment was developed at the Johnson Space Center. 12.0 IMAX During the STS-79 mission, the crew will use an onboard IMAX camera to document activities on Atlantis and Mir. After the mission, selected still images from the film will be made available to the public via the Internet. Sections of the film will be transferred to videotape and will be broadcast on NASA-TV for subsequent use by the media. NASA is using the IMAX film medium to document its space activities and better illustrate them for the public. This system, developed by the Imax Corp., Toronto, Canada, uses specially designed motion picture cameras and projectors to record and display high-definition, large screen pictures. NASA has flown IMAX camera systems on many Shuttle missions. Footage from STS-79, as well as the recent STS-63, STS-71, and STS-74 missions will be incorporated in a large- format feature film about NASA's cooperation with Russia. The IMAX system consists of a space-qualified 65mm camera, lenses, rolls of film, lights and other equipment necessary for filming. The IMAX and supporting equipment are stowed in the middeck of the orbiter. An audio tape recorder with microphones will be used in the crew compartment to record audio sounds and crew comments during camera operations. 13.0 Shuttle Amateur Radio Experiment (SAREX) Ham radio operators and students will attempt to make radio contacts with the orbiting Shuttle as part of the Shuttle Amateur Radio Experiment, SAREX, during STS-79. Amateur radio has been flying aboard Space Shuttles since 1983. Amateur radio operators from around the world will point their antennas at Atlantis, hoping to find the astronauts on the air. Some of these amateurs have volunteered to assist student groups who have prepared questions to ask the astronauts during specially-scheduled contact times. To make their radio contacts, the astronauts will use a radio on board the Shuttle, on frequencies used by ham radio operators. For the students who participate in SAREX, the contact is the culmination of months of hard work. Many of the students have studied space science and communications, and have trained to use ham radio equipment and Shuttle- tracking computer software. To operate amateur radio from the Space Shuttle, one or more of the astronauts must have an amateur radio license. Mission Specialist Jay Apt's amateur radio call sign is N5QWL. Apt has flown on three previous Shuttle missions and has operated amateur radio during each flight. John Blaha also will serve as a Mission Specialist, and his ham radio call sign is KC5TZQ. Astronaut Carl Walz is KC5TIE; he participated in SAREX from Columbia during STS-65 in July 1994, before earning his amateur radio license. During SAREX missions, the astronauts will typically make the following types of amateur radio contacts: Scheduled radio contacts with schools; Random radio contacts with the amateur radio community; Personal contacts with the astronauts' families. SAREX is sponsored by the American Radio Relay League (ARRL), The Radio Amateur Satellite Corporation (AMSAT) and NASA. SAREX is supported by the Federal Communications Commission. ADDITIONAL INFORMATION FOR AMATEUR RADIO OPERATORS Since this flight is a Shuttle-Mir docking mission, and SAREX and Mir amateur radio stations sometimes share the same downlink frequency (145.55 MHz), the SAREX Working Group has decided to use the following frequencies during this mission. The crew will use separate receive and transmit frequencies. PLEASE do not transmit on the Shuttle's DOWNLINK frequency. The DOWNLINK is your receiving frequency. The UPLINK is your transmitting frequency. FM Voice Downlink: 145.84 MHz FM Voice Uplink: 144.45, 144.47 MHz The crew will not favor either uplink frequency, so your ability to communicate with SAREX will be the "luck of the draw." Transmit only when the Shuttle is within range of your station, and when the Shuttle's station is on-the-air. CALL SIGNS: FM voice call signs N5QWL, KC5TIE, and KC5TZQ Members of the Goddard Amateur Radio Club (Greenbelt, MD) re-transmit live, Shuttle air-to-ground audio over the amateur frequencies from their club station, WA3NAN. To listen-in, tune to amateur radio high frequency (HF) bands at 3.86, 7.185, 14.295, 21.395, and 28.65 megahertz (MHz) and in the Maryland/DC area on a very high frequency (VHF) band at 147.45 MHz. 14.0 STS-79 Crew Biographies William F.
