Yee) Subject: STS-34 Press Kit [3 of 3] [Revised] (Forwarded) ordnance inhibits for the first SRM will be removed. The belly of the orbiter already will have been oriented towards the IUS/Galileo to protect orbiter windows from the IUS's plume. The IUS will recompute the first ignition time and maneuvers necessary to attain the proper attitude for the first thrusting period. When the proper transfer orbit opportunity is reached, the IUS computer will send the signal to ignite the first stage motor 60 minutes after deployment. After firing approximately 150 seconds, the IUS first stage will have expended its propellant and will be separated from the IUS second stage. Approximately 140 seconds after first-stage burnout, the second- stage motor will be ignited, thrusting about 108 seconds. The IUS second stage then will separate and perform a final collision/contamination avoidance maneuver before deactivating. SHUTTLE SOLAR BACKSCATTER ULTRAVIOLET INSTRUMENT The Shuttle Solar Backscatter Ultraviolet (SSBUV) instrument was developed by NASA to calibrate similar ozone measuring space-based instruments on the National Oceanic and Atmospheric Administration's TIROS satellites (NOAA-9 and -11). The SSBUV will help scientists solve the problem of data reliability caused by calibration drift of solar backscatter ultraviolet (SBUV) instruments on orbiting spacecraft. The SSBUV uses the Space Shuttle's orbital flight path to assess instrument performance by directly comparing data from identical instruments aboard the TIROS spacecraft, as the Shuttle and the satellite pass over the same Earth location within a 1-hour window. These orbital coincidences can occur 17 times per day. The SBUV measures the amount and height distribution of ozone in the upper atmosphere. It does this by measuring incident solar ultraviolet radiation and ultraviolet radiation backscattered from the Earth's atmosphere. The SBUV measures these parameters in 12 discrete wavelength channels in the ultraviolet. Because ozone absorbs in the ultraviolet, an ozone measurement can be derived from the ratio of backscatter radiation at different wavelengths, providing an index of the vertical distribution of ozone in the atmosphere. Global concern over the depletion of the ozone layer has sparked increased emphasis on developing and improving ozone measurement methods and instruments. Accurate, reliable measurements from space are critical to the detection of ozone trends and for assessing the potential effects and development of corrective measures. The SSBUV missions are so important to the support of Earth science that six additional missions have been added to the Shuttle manifest for calibrating ozone instruments on future TIROS satellites. In addition, the dates of the four previously manifested SSBUV flights have been accelerated. The SSBUV instrument and its dedicated electronics, power, data and command systems are mounted in the Shuttle's payload bay in two Get Away Special canisters, an instrument canister and a support canister. Together, they weigh approximately 1200 lb. The instrument canister holds the SSBUV, its specially designed aspect sensors and in-flight calibration system. A motorized door assembly opens the canister to allow the SSBUV to view the sun and Earth and closes during the in-flight calibration sequence. The support canister contains the power system, data storage and command decoders. The dedicated power system can operate the SSBUV for a total of approximately 40 hours. The SSBUV is managed by NASA's Goddard Space Flight Center, Greenbelt, Md. Ernest Hilsenrath is the principal investigator. GROWTH HORMONE CONCENTRATIONS AND DISTRIBUTION IN PLANTS The Growth Hormone Concentration and Distribution in Plants (GHCD) experiment is designed to determine the effects of microgravity on the concentration, turnover properties, and behavior of the plant growth hormone, Auxin, in corn shoot tissue (Zea Mays). Mounted in foam blocks inside two standard middeck lockers, the equipment consists of four plant cannisters, two gaseous nitrogen freezers and two temperature recorders. Equipment for the experiment, excluding the lockers, weighs 97.5 pounds. A total of 228 specimens (Zea Mays seeds) are "planted" in special filter, paper-Teflon tube holders no more than 56 hours prior to flight. The seeds remain in total darkness throughout the mission. The GHCD experiment equipment and specimens will be prepared in a Payload Processing Facility at KSC and placed in the middeck lockers. The GHCD lockers will be installed in the orbiter middeck within the last 14 hours before launch. No sooner than 72 hours after launch, mission specialist Ellen Baker will place two of the plant cannisters into the gaseous nitrogen freezers to arrest the plant growth and preserve the specimens. The payload will be restowed in the lockers for the remainder of the mission. After landing, the payload must be removed from the orbiter within 2 hours and will be returned to customer representatives at the landing site. The specimens will be examined post flight for microgravity effects. The GHCD experiment is sponsored by NASA Headquarters, the Johnson Space Center and Michigan State University. POLYMER MORPHOLOGY The Polymer Morphology (PM) experiment is a 3M-developed organic materials processing experiment designed to explore the effects of microgravity on polymeric materials as they are processed in space. Since melt processing is one of the more industrially significant methods for making products from polymers, it has been chosen for study in the PM experiment. Key aspects of melt processing include polymerization, crystallization and phase separation. Each aspect will be examined in the experiment. The polymeric systems for the first flight of PM include polyethelyne, nylon-6 and polymer blends. The apparatus for the experiment includes a Fournier transform infrared (FTIR) spectrometer, an automatic sample manipulating system and a process control and data acquisition computer known as the Generic Electronics Module (GEM). The experiment is contained in two separate, hermetically sealed containers that are mounted in the middeck of the orbiter. Each container includes an integral heat exchanger that transfers heat from the interior of the containers to the orbiter's environment. All sample materials are kept in triple containers for the safety of the astronauts. The PM experiment weighs approximately 200 lb., occupies three standard middeck locker spaces (6 cubic ft., total) in the orbiter and requires 240 watts to operate. Mission specialists Franklin R. Chang-Diaz and Shannon W. Lucid are responsible for the operation of the PM experiment on orbit. Their interface with the PM experiment is through a small, NASA-supplied laptop computer that is used as an input and output device for the main PM computer. This interface has been programmed by 3M engineers to manage and display the large quantity of data that is available to the crew. The astronauts will have an active role in the operation of the experiment. In the PM experiment, infrared spectra (400 to 5000 cm-1) will be acquired from the FTIR by the GEM computer once every 3.2 seconds as the materials are processed on orbit. During the 100 hours of processing time, approximately 2 gigabytes of data will be collected. Post flight, 3M scientists will process the data to reveal the effects of microgravity on the samples processed in space. The PM experiment is unique among material processing experiments in that measurements characterizing the effects of microgravity will be made in real time, as the materials are processed in space. In most materials processing space experiments, the materials have been processed in space with little or no measurements made during on-orbit processing and the effects of microgravity determined post facto. The samples of polymeric materials being studied in the PM experiment are thin films (25 microns or less) approximately 25 mm in diameter. The samples are mounted between two infrared transparent windows in a specially designed infrared cell that provides the capability of thermally processing the samples to 200 degrees Celsius with a high degree of thermal control. The samples are mounted on a carousel that allows them to be positioned, one at a time, in the infrared beam where spectra may be acquired. The GEM provides all carousel and sample cell control. The first flight of PM will contain 17 samples. The PM experiment is being conducted by 3M's Space Research and Applications Laboratory. Dr. Earl L. Cook is 3M's Payload Representative and Mission Coordinator. Dr. Debra L. Wilfong is PM's Science Coordinator, and James E. Steffen is the Hardware Coordinator. The PM experiment, a commercial development payload, is sponsored by NASA's Office of Commercial Programs. The PM experiment will be 3M's fifth space experiment and the first under the company's 10-year Joint Endeavor Agreement with NASA for 62 flight experiment opportunities. Previous 3M space experiments have studied organic crystal growth from solution (DMOS/1 on mission STS 51-A and DMOS/2 on STS 61-B) and organic thin film growth by physical vapor treatment (PVTOS/1 on STS 51-I and PVTOS/2 on mission STS-26). STUDENT EXPERIMENT Zero Gravity Growth of Ice Crystals From Supercooled Water With Relation To Temperature (SE82-15) This experiment, proposed by Tracy L. Peters, formerly of Ygnacio High School, Concord, Calif., will observe the geometric ice crystal shapes formed at supercooled temperatures, below 0 degrees Celsius, without the influence of gravity. Liquid water has been discovered at temperatures far below water's freezing point. This phonomenon occurs because liquid water does not have a nucleus, or core, around which to form the crystal. When the ice freezes at supercold temperatures, the ice takes on many geometric shapes based on the hexagon. The shape of the crystal primarily depends on the supercooled temperature and saturation of water vapor. The shapes of crystals vary from simple plates to complex prismatic crystals. Many scientists have tried to determine the relation between temperature and geometry, but gravity has deformed crystals, caused convection currents in temperature-controlled apparatus, and caused faults in the crystalline structure. These all affect crystal growth by either rapid fluctuations of temperature or gravitational influence of the crystal geometry. The results of this experiment could aid in the design of radiator cooling and cryogenic systems and in the understanding of high-altitude meteorology and planetary ring structure theories. Peters is now studying physics at the University of California at Berkeley. His teacher advisor is James R. Cobb, Ygnacio High School; his sponsor is Boeing Aerospace Corp., Seattle. Peters also was honored as the first four-time NASA award winner at the International Science and Engineering Fair (ISEF), which recognizes student's creative scientific endeavors in aerospace research. At the 1982 ISEF, Peters was one of two recipients of the Glen T. Seaborg Nobel Prize Visit Award, an all-expense-paid visit to Stockholm to attend the Nobel Prize ceremonies, for his project "Penetration and Diffusion of Supersonic Fluid." MESOSCALE LIGHTNING EXPERIMENT The Space Shuttle will again carry the Mesoscale Lightning Experiment (MLE), designed to obtain nighttime images of lightning in order to better understand the global distribution of lightning, the interrelationships between lightning events in nearby storms, and relationships between lightning, convective storms and precipitation. A better understanding of the relationships between lightning and thunderstorm characteristics can lead to the development of applications in severe storm warning and forecasting, and early warning systems for lightning threats to life and property. In recent years, NASA has used both Space Shuttle missions and high-altitude U-2 aircraft to observe lightning from above convective storms. The objectives of these observations have been to determine some of the baseline design requirements for a satellite-borne optical lightning mapper sensor; study the overall optical and electrical characteristics of lightning as viewed from above the cloudtop; and investigate the relationship between storm electrical development and the structure, dynamics and evolution of thunderstorms and thunderstorm systems. The MLE began as an experiment to demonstrate that meaningful, qualitative observations of lightning could be made from the Shuttle. Having accomplished this, the experiment is now focusing on quantitative measurements of lightning characteristics and observation simulations for future space-based lightning sensors. Data from the MLE will provide information for the development of observation simulations for an upcoming polar platform and Space Station instrument, the Lightning Imaging Sensor (LIS). The lightning experiment also will be helpful for designing procedures for using the Lightning Mapper Sensor (LMS), planned for several geostationary platforms. In this experiment, Atlantis' payload bay camera will be pointed directly below the orbiter to observe nighttime lightning in large, or mesoscale, storm systems to gather global estimates of lightning as observed from Shuttle altitudes. Scientists on the ground will analyze the imagery for the frequency of lightning flashes in active storm clouds within the camera's field of view, the length of lightning discharges, and cloud brightness when illuminated by the lightning discharge within the cloud. If time permits during missions, astronauts also will use a handheld 35mm camera to photograph lightning activity in storm systems not directly below the Shuttle's orbital track. Data from the MLE will be associated with ongoing observations of lightning made at several locations on the ground, including observations made at facilities at the Marshall Space Flight Center, Huntsville, Ala.; Kennedy Space Center, Fla.; and the NOAA Severe Storms Laboratory, Norman, Okla. Other ground-based lightning detection systems in Australia, South America and Africa will be intergrated when possible. The MLE is managed by the Marshall Space Flight Center. Otha H. Vaughan Jr., is coordinating the experiment. Dr. Hugh Christian is the project scientist, and Dr. James Arnold is the project manager. IMAX The IMAX project is a collaboration between NASA and the Smithsonian Institution's National Air and Space Museum to document significant space activities using the IMAX film medium. This system, developed by the IMAX Systems Corp., Toronto, Canada, uses specially designed 70mm film cameras and projectors to record and display very high definition large-screen color motion pictures. IMAX cameras previously have flown on Space Shuttle missions 41-C, 41-D and 41-G to document crew operations in the payload bay and the orbiter's middeck and flight deck along with spectacular views of space and Earth. Film from those missions form the basis for the IMAX production, "The Dream is Alive." On STS 61-B, an IMAX camera mounted in the payload bay recorded extravehicular activities in the EAS/ACCESS space construction demonstrations. The IMAX camera, most recently carried aboard STS-29, will be used on this mission to cover the deployment of the Galileo spacecraft and to gather material on the use of observations of the Earth from space for future IMAX films. AIR FORCE MAUI OPTICAL SITE CALIBRATION TEST The Air Force Maui Optical Site (AMOS) tests allow ground-based electro-optical sensors located on Mt. Haleakala, Maui, Hawaii, to collect imagery and signature data of the orbiter during cooperative overflights. Scientific observations made of the orbiter while performing Reaction Control System thruster firings, water dumps or payload bay light activation are used to support the calibration of the AMOS sensors and the validation of spacecraft contamination models. AMOS tests have no payload-unique flight hardware and only require that the orbiter be in predefined attitude operations and lighting conditions. The AMOS facility was developed by Air Force Systems Command (AFSC) through its Rome Air Development Center, Griffiss Air Force Base, N.Y., and is administered and operated by the AVCO Everett Research Laboratory, Maui. The principal investigator for the AMOS tests on the Space Shuttle is from AFSC's Air Force Geophysics Laboratory, Hanscom Air Force Base, Mass. A co-principal investigator is from AVCO. Flight planning and mission support activities for the AMOS test opportunities are provided by a detachment of AFSC's Space Systems Division at Johnson Space Center, Houston. Flight operations are conducted at JSC Mission Control Center in coordination with the AMOS facilities located in Hawaii. SENSOR TECHNOLOGY EXPERIMENT The Sensor Technology Experiment (STEX) is a radiation detection experiment designed to measure the natural radiation background. The STEX is a self-contained experiment with its own power, sensor, computer control and data storage. A calibration pack, composed of a small number of passive threshold reaction monitors, is attached to the outside of the STEX package. Sponsored by the Strategic Defense Initiative Organization, the STEX package weighs approximately 50 pounds and is stowed in a standard middeck locker throughout the flight. PAYLOAD AND VEHICLE WEIGHTS Vehicle/Payload Weight (Pounds) Orbiter (Atlantis) Empty 172,018 Galileo/IUS (payload bay) 43,980 Galileo support hardware (middeck) 59 SSBUV (payload bay) 637 SSBUV support 578 DSO 49 DTO 170 GHCD 130 IMAX 269 MLE 15 PM 219 SSIP 70 STEX 52 Orbiter and Cargo at SRB Ignition 264,775 Total Vehicle at SRB Ignition 4,523,810 Orbiter Landing Weight 195,283 SPACEFLIGHT TRACKING AND DATA NETWORK Primary communications for most activities on STS-34 will be conducted through the orbiting Tracking and Data Relay Satellite System (TDRSS), a constellation of three communications satellites in geosynchronous orbit 22,300 miles above the Earth. In addition, three NASA Spaceflight Tracking and Data Network (STDN) ground stations and the NASA Communications Network (NASCOM), both managed by Goddard Space Flight Center, Greenbelt, Md., will play key roles in the mission. Three stations -- Merritt Island and Ponce de Leon, Florida and the Bermuda -- serve as the primary communications during the launch and ascent phases of the mission. For the first 80 seconds, all voice, telemetry and other communications from the Space Shuttle are relayed to the mission managers at Kennedy and Johnson Space Centers by way of the Merritt Island facility. At 80 seconds, the communications are picked up from the Shuttle and relayed to the two NASA centers from the Ponce de Leon facility, 30 miles north of the launch pad. This facility provides the communications between the Shuttle and the centers for 70 seconds, or until 150 seconds into the mission. This is during a critical period when exhaust from the solid rocket motors "blocks out" the Merritt Island antennas. The Merritt Island facility resumes communications to and from the Shuttle after those 70 seconds and maintains them until 6 minutes, 30 seconds after launch when communications are "switched over" to Bermuda. Bermuda then provides the communications until 11 minutes after liftoff when the TDRS-East satellite acquires the Shuttle. TDRS-West acquires the orbiter at launch plus 50 minutes. The TDRS-East and -West satellites will provide communications with the Shuttle during 85 percent or better of each orbit. The TDRS-West satellite will handle communications with the Shuttle during its descent and landing phases. STS-34 CARGO CONFIGURATION (illustration) CREW BIOGRAPHIES Donald E. Williams, 47, Capt., USN, will serve as commander. Selected as an astronaut in January 1978, he was born in Lafayette, Ind. Williams was pilot for STS-51D, the fourth flight of Discovery, launched April 12, 1985. During the mission, the seven-member crew deployed the Anik-C communications satellite for Telesat of Canada and the Syncom IV-3 satellite for the U.S. Navy. A malfunction in the Syncom spacecraft resulted in the first unscheduled extravehicular, rendezvous and proximity operation for the Space Shuttle in an attempt to activate the satellite. He graduated from Otterbein High School, Otterbein, Ind., in 1960 and received his B.S. degree in mechanical engineering from Purdue University in 1964. Williams completed his flight training at Pensacola, Fla., Meridian, Miss., and Kingsville, Texas, and earned his wings in 1966. During the Vietnam Conflict, Williams completed 330 combat missions. He has logged more than 5,400 hours flying time, including 5,100 in jets, and 745 aircraft carrier landings. Michael J. McCulley, 46, Cdr., USN, will be pilot on this flight.
