Galileo will also fly by asteroid Ida, at 2400 kilometers, on August 28, 1993. The spacecraft's performance and condition are excellent except that the high-gain antenna is only partly deployed; science and engineering data are being transmitted via the low-gain antenna, which the mission team is planning to use for the Jupiter mission and the Ida encounter. Galileo was launched October 18, 1989, flew by Venus in 1990 and Earth in 1990 and 1992 for gravity assists, and flew by asteroid Gaspra in October 1991 for scientific observation. MAGELLAN: The Magellan spacecraft controllers are conducting an aerobraking program, begun May 25, to lower and circularize the spacecraft's orbit, permitting higher-resolution global gravity mapping. In this 80-day innovative procedure, the spacecraft dips into Venus's upper atmosphere each orbit, slowing and shortening the orbit without expending fuel. Magellan was launched May 4, 1989. It radar-mapped more than 98 percent of Venus's surface from September 1990 to September 1992, and surveyed parts of the gravitational field from its elliptical orbit for the next 8 months. MARS OBSERVER: Spacecraft health and performance are normal. Mars Observer is scheduled to enter Mars orbit August 24, 1993; it will be maneuvered into a mapping orbit by November 8 and science operations are planned to start November 24. Mars Observer was launched September 25, 1992. TOPEX/POSEIDON: The satellite is healthy, and all scientific instruments are performing normally, typically providing three playbacks per day. The mission is mapping global sea level changes, reflecting seasonal warming and cooling and winds. So far it has accumulated 6 months of data. TOPEX/Poseidon was launched August 10, 1992. ULYSSES: The spacecraft is in a highly inclined solar orbit, now more than 33 degrees south relative to the Sun's equator, in transit from its Jupiter gravity assist in February 1992 toward its solar polar passages (about 80 degrees south and north) in 1994 and 1995. Spacecraft condition and performance are excellent, with Ulysses gathering data on the heliosphere -- the realm dominated by the solar wind, a stream of charged particles flowing from the Sun. The Ulysses spacecraft was built by the European Space Agency and launched October 6, 1990. VOYAGER 1 and 2: The two Voyager spacecraft are continuing their Interstellar Mission, having remotely detected the heliopause, the boundary between the solar magnetosphere and interstellar space, for the first time last month. Voyager 1, launched September 5, 1977, is currently 7.9 billion kilometers (4.9 billion miles) from the Sun after flying by Jupiter and Saturn in 1979 and 1980; Voyager 2, launched August 20, 1977, to fly by Jupiter (1979), Saturn (1981), Uranus (1986) and Neptune (1989), is now 6 billion kilometers (3.8 billion miles) from the Sun. ##### Source:NASA Spacelink Modem:205-895-0028 Internet:192.149.89.61 =--=--=-END-=--=--= =--=--=START=--=--= NASA Spacelink File Name:930630.REL 6/30/93: STS-51 PREFLIGHT BRIEFINGS SET FOR JULY 6 Michael Braukus Headquarters, Washington, D.C.

Diller June 30, 1993 KSC Release No. 73-93 The Wake Shield Facility (WSF), a primary payload for mission STS-60, has arrived at Cape Canaveral to begin final prelaunch assembly and checkout. The spacecraft will fly aboard the Space Shuttle Discovery targeted for launch the second week in November. The parabolic-shaped WSF is 12 feet in diameter and includes a communications and avionics system, solar cells and batteries, and a propulsion thruster. The experiment will take advantage of the near vacuum of space to attempt to grow innovative thin film materials for use in electronics. It will be deployed by the remote manipulator arm, and fly in formation with Discovery at a distance of up to 46 statute miles from the orbiter for 56 hours. It will then be retrieved from space, again using the remote manipulator arm. WSF is undergoing initial processing in NASA's Hangar S on Cape Canaveral Air Force Station. In mid-September it will be moved to the Vertical Processing Facility in the KSC Industrial Area where tests will verify its compatibility with the Space Shuttle. The payload is scheduled to be transferred to the pad approximately one month later, about mid-October. WSF development is sponsored by the Space Vacuum Epitaxy Center in Houston, Texas which is a NASA Center for the Commercial Development of Space (CCDS). Experiments are also being sponsored by NASA, the Air Force and Army, and Case Western Reserve University in Cleveland, also part of NASA's CCDS program.

The crew was awakened at 11:37 p.m. CDT last night to begin their seventh day aboard to the song "I Got You," performed by James Brown, a favorite tune of Payload Commander David Low. Included in the day's work will be a second day of test runs of the Fluid Aquisition and Resupply Experiment by Mission Specialist Jeff Wisoff. FARE, in the shuttle's middeck, consists of two transparent tanks linked by a series of filters and special plumbing, studies technology for transferring fluid from one container to another with a minimum of bubbling in weightlessness. Fluids and gas do not naturally separate in weightlessness as they do in Earth's gravity when fluid collecting at the bottom of a container and the air above. FARE's technology may one day lead to a method for refueling spacecraft in orbit. Other experiments later today will include a study of an astronaut's body posture in orbit. In weightlessness, the spine lengthens and other changes take place which result in a unique posture. The study will photograph and videotape crew members floating in a relaxed position, and is hoped to provide assistance in improving the design of future spacecraft to make them as comfortable and habitable as possible. For the same reasons, the crew will evaluate lighting conditions and noise levels on the shuttle and in the Spacehab today. Endeavour remains in excellent mechanical health in an orbit of 256 by 209 nautical mile orbit circling Earth each 93 minutes. --end-- Source:NASA Spacelink Modem:205-895-0028 Internet:192.149.89.61 =--=--=-END-=--=--= =--=--=START=--=--= NASA Spacelink File Name:6_2_2_45_11_17.TXT MCC Status Report #15 MISSION CONTROL CENTER STS-57 Status Report #15 Monday, June 28, 1993, 5 a.m. CDT Endeavour's crew this morning checked the controls the shuttle will use to return to Earth, worked to unclog a line in a water recycling experiment, and planned to speak with reporters about their flight in an early morning press conference. Mission Specialist Nancy Sherlock performed an impromptu plumbing job on the Environmental Control Systems Flight Experiment, a study of wastewater purification equipment that may be used aboard future spacecraft. EFE uses a mixture of water and potassium idodide to simulate wastewater. The solution is pumped through a series of filters to purify it. During the flight, experimenters have seen a reduced flow of water through the device and opted to perform the maintenance procedure. Sherlock loosened a fitting on one water line inside the experiment, wrapped the loose fitting with an absorbent diaper, and, using a laptop computer onboard, turned a pump on the experiment into reverse for about 20 minutes in an attempt to flush out the clog. Sherlock then retightened the fitting and put the experiment back into normal operation for ground experimenters, who will now spend about an hour and a half watching it run to see if the clog has been cleared. Meanwhile, Commander Ron Grabe and Pilot Brian Duffy found everything in order during a standard check of Endeavour's flight controls and cockpit displays performed in preparation for the trip home. A test firing of the shuttle's steering jets is scheduled later. Endeavour is currently set to touchdown at 7:44 a.m. CDT Tuesday at Florida's Kennedy Space Center. However, enough supplies and electricity are available onboard to add another day in orbit to the flight, and shuttle managers will consider that option when they meet later this moring. A second opportunity for landing Tuesday at Kennedy would mean a 9:24 a.m. touchdown. For Tuesday's first opportunity, Endeavour would fire its engines at 6:34 a.m. to begin its descent. For the later landing, Endeavour's engines would fire at 8:14 a.m. The crew was awakened at 10:37 p.m. Sunday for their eighth day in orbit to Perry Como's "Catch a Falling Star." Endeavour is in a 256 by 208 nautical mile orbit, completing a circle of Earth every 93 minutes, 21 seconds. --end-- Source:NASA Spacelink Modem:205-895-0028 Internet:192.149.89.61 =--=--=-END-=--=--= =--=--=START=--=--= NASA Spacelink File Name:6_2_2_45_11_19.TXT MCC Status Report #17 MISSION CONTROL CENTER STS-57 Status Report #17 Monday, June 28, 1993, 3 p.m. CDT Endeavour's six-member crew went to sleep a few minutes after 2 p.m. CDT today after completing their eighth work day in space. Earlier today, Ron Grabe and Brian Duffy checked the equipment the shuttle will use for tomorrow's Florida landing. Nancy Sherlock, aided by Janice Voss, attempted a repair of a water recycling experiment. The entire crew spoke to reporters about their flight in a 6:37 a.m. CDT press conference. Endeavour is currently set to touch down at 7:45 a.m. central Tuesday at Florida's Kennedy Space Center. A second opportunity for a landing tomorrow at Kennedy would mean a 9:23 a.m. touchdown. For tomorrow's early opportunity, Endeavour would fire its engines at 6:39 a.m. to begin its descent. For the later landing, Endeavour's engines would fire at 8:19 a.m. The Spaceflight Meterology Group's latest weather forecast remains the same for Tuesday morning. The Planning Team and Entry Team flight controllers will monitor weather conditions leading up to Endeavour's scheduled landing time. Curent predictions are generally favorable with a possibility of low clouds and rain showers within 30 miles of KSC's runway 33 at the first landing opportunity, and a chance of rising winds at the time of the second opportunity. Meanwhile, Commander Ron Grabe and Pilot Brian Duffy found everything in order during standard checks of Endeavour's flight controls, cockpit displays and steering jets performed in preparation for the trip home. Endeavour is in excellent condition for tomorrow's landing. The STS-57 crew will wake up at 10:07 p.m. CDT tonight to begin their final steps in powering down and packing up the experiments on board in preparation for their Tuesday landing. Endeavour is in a 256 by 208 nautical mile orbit, completing a circle of Earth every 93 minutes.

Low clouds and the possibility of rain showers in the vicinity of the Shuttle landing facility have prevented Endeavour's landing so far. During their shortened work day, the crew set up the bicycle ergometer and monitoring equipment for an experiment investigating aerobic exercise as a countermeasure to the dizziness astronauts sometimes experience upon returning to Earth's gravity. The study compares readings from various body systems as the astronaut exercises vigorously on the stationary bicycle. Measurements from exercise performed pre-flight, on the third flight day, the day before landing, and post-flight are compared to help determine if aerobic exercise could be used as an effective countermeasure against the physiological effects of weightlessness during longer duration space missions. Thursday's landing at Kennedy Space Center is scheduled at 7:52 a.m. CDT, requiring Endeavour's orbital maneuvering systems engines to fire at 6:41 a.m. CDT to bring Endeavour back into the Earth's atmosphere. Should weather be unfavorable at KSC, landing would occur at Edwards Air Force Base, California at 9:21 a.m. CDT. The deorbit engine firing would occur at 8:10 a.m. CDT for the California landing. Endeavour's systems continue to function well as the Orbiter circles the Earth every 93 minutes in a 256 by 208 nautical mile orbit. -end- Source:NASA Spacelink Modem:205-895-0028 Internet:192.149.89.61 =--=--=-END-=--=--= =--=--=START=--=--= NASA Spacelink File Name:6_2_2_45_12.TXT 6/30/93: SPACELINK NOTE--ENDEAVOUR LANDING Unfavorable weather conditions have delayed the landing of Space Shuttle Endeavour yet another day. Landing is now scheduled for tomorrow at 8:53 a.m. EDT at the Kennedy Space Center. If weather conditions should prove unsuitable at Kennedy, Endeavour's landing will be at the back-up facilities at Edwards Air Force Base, California. Previously issued landing statements and plans follow: 6/29/93: STS-57 LANDING Because of weather restrictions today, Endeavour's STS-57 mission has been extended a day. Expecting to land this morning, crew members packed experiments and flight gear and checked the flight control systems. Tomorrow's landing attempt is targeted for 7:59 a.m. EDT at the Kenndey Space Center. With the one day extension, the STS-57 mission will have lasted 9 days. 6/28/93: ENDEAVOUR SCHEDULED TO LAND AT KSC TOMORROW MORNING Mitch Varnes June 28, 1993 KSC Release No. 74-93 Nearly eight days after rocketing into space on the year's fourth Shuttle mission, the orbiter Endeavour and a six member crew are preparing to return home tomorrow morning. Endeavour is now scheduled to land at the Shuttle Landing Facility (SLF) at 8:44 a.m. EDT on Tuesday. The deorbit burn to bring Endeavour back to Earth is planned to take place at 7:34 a.m., 70 minutes before landing. The nominal landing time of 8:44 a.m. is the first of two oppor- tunities Endeavour has to land at its Florida launch site. The ship's second chance to land at KSC is at 10:24 tomorrow morning. Current weather forecasts for tomorrow morning indicate marginal but potentially favorable conditions for a KSC landing. Endeavour will reenter Earth's atmosphere over the South Pacific and head eastward toward the three-mile-long Shuttle runway. The spaceship will soar over Baja California, Mexico, southern Texas and the Gulf of Mexico before reaching the west central Florida coast. Mission commander Ron Grabe will then guide NASA's newest orbiter high above Orlando and Titusville before bringing the Shuttle in for a landing onto the concrete runway. Endeavour's twin sonic booms should be audible over much of Central Florida. Endeavour roared away from KSC launch pad 39-B on Monday, June 21 at 9:07 a.m. EDT. STS-57 is the fourth flight of Endeavour and the 56th Space Shuttle mission. During the course of the eight- day flight, the astronauts successfully conducted scores of biomedical and materials sciences experiments inside the pres- surized Spacehab module. Two astronauts particpated in a spacewalk and the European Retrievable Carrier (EURECA) was retrieved by the crew and stowed inside Endeavour's payload bay. EURECA was deployed from the Shuttle Atlantis in the summer of 1992 and contains several experiments to study the longterm ef- fects of exposure to microgravity. Endeavour will next fly on mission STS-61, now targeted for launch in December. KSC's Shuttle Landing Facility has previously served as the land- ing site for 15 Shuttle missions. The first KSC landing occurred at the end of mission STS-41-B, on Feb. 11, 1984. The most recent KSC landing occurred on April 17, 1993 when STS-56 Com- mander Ken Cameron guided Discovery to a successful landing. The KSC news center will open at 5 a.m. on Tuesday to support Endeavour's landing. Buses will begin transporting members of the news media to the landing facility beginning at 5:15 a.m. The last press bus will leave at 7:15 a.m., sharp.

June 30, 1993 Barbara Schwartz Johnson Space Center, Houston NOTE TO EDITORS: N93-37 A series of background briefings for Space Shuttle mission STS-51 will be held July 6 at the Johnson Space Center, Houston, beginning at 10:00 a.m. EDT. STS-51 will be the 17th flight of the Space Shuttle Discovery. The mission will feature the deployment of the Advanced Communications Technology Satellite (ACTS), as well as the deployment and retrieval of the Orbiting and Retrievable Far and Extreme Ultraviolet Spectrometer (ORFEUS) which will be mounted on the Shuttle Pallet Satellite (SPAS). Following its deployment from the Shuttle, the ACTS- will be placed in a geostationary orbit by a Transfer Orbit Stage (TOS) where it will be used as a space-based testbed for new satellite communications technology. During its week-long free-flight, the ORFEUS/SPAS will gather information on how stars are formed and will study properties of the interstellar medium. A briefing agenda is attached. All briefings will be carried on NASA Select television with two-way audio for questions from participating NASA locations. NASA Select is carried on GE SATCOM F2R, transponder 13, 72 degrees west longitude.
