Yee) Subject: NASA Headline News for 04/08/91 (Forwarded) Headline News Internal Communications Branch (P-2) NASA Headquarters Monday, April 8, 1991 Audio Service: 202 / 755-1788 This is NASA Headline News for Monday, April 8, 1991 . . . The STS-37 mission continues to go well. The orbiter and all five crewmembers are in good shape and the Gamma Ray Observatory has been successfully deployed. Orbiter anomalies to date are very few, the major item being the failed reaction control system jet. That jet failed about 10 minutes after launch on Friday. It appears to be similar to previous instances on other orbiters and poses no impact to the mission. On Sunday, astronauts Jerry Ross and Jay Apt suited up and went outside for the first contingency spacewalk in six years. The cause of the contingency spacewalk was a recalcitrant high-gain antenna on the Gamma Ray Observatory, which had failed to deploy in six attempts, including two which had the robot arm gently shaking the payload to help free the antenna. Ross and Apt were outside at 2:39 pm EDT and within 17 minutes had freed the antenna. Following their success, the spacewalkers continued outside, this time setting up equipment which is being used today in the space station assembly experiment. Sunday's was the first unscheduled spacewalk since the STS-51D flight in April 1985. During that flight, astronauts Jeff Hoffman and David Griggs attached a "flyswatter" to the end of the remote manipulator arm to help activate a switch on the side of the Hughes Syncom satellite. That satellite was later retrieved and repaired on a subsequent mission. Atlantis is scheduled to land at Dryden Flight Research Facility, California, Wednesday at 12:34 pm EDT. * * * * * * * * * * * * * * * * Jet Propulsion Laboratory flight controllers report that operations are proceeding smoothly to bring the Galileo spacecraft out of the safe mode it went into on March 26. Galileo's onboard computer system experienced a transient signal which caused one of the two redundant computers to shut itself off, causing the other to enter the safe mode. JPL expects to have the spacecraft back and fully functioning by April 25. The spacecraft is now 37 million miles from Earth and travelling at a heliocentric velocity of 64,400 miles per hour. JPL also reports that routine mission operations and cruise-mode data collection activities are being carried out by the Ulysses spacecraft. The spacecraft's fields and particles sensors picked up significant amounts of science data during the major solar flare which occurred 10 days ago. Ulysses is approaching the halfway point in its journey from Earth to Jupiter -- its first mission milepost. The spacecraft is 222 million miles from Earth and heading towards Jupiter at the heliocentric velocity of 53,770 miles per hour. * * * * * * * * * * * * * * * * The Marshall Space Flight Center will begin a series of sub-scale test firings to evaluate materials intended for use in the Advanced Solid Rocket Motor on Wednesday, April 10.

The test will be conducted at Marshall's East Test Area by Aerojet Corp., ASRM Division, Iuka, Miss., under contract to Lockheed Missiles and Space Co., Sunnyvale, Calif.

You'd have to convert to absolute temperatures first (e.g. is one third of 0F 0F?). Not that the number should mean anything, but I come up with a value of about -7F. -- Chris Jones clj@ksr.com {uunet,harvard,world}!ksr!clj ------------------------------ Date: 8 Apr 91 11:19:55 GMT From: udecc.engr.udayton.edu!blackbird.afit.af.mil!tkelso@tut.cis.ohio-state.edu (TS Kelso) Subject: NASA Prediction Bulletins: Space Shuttle The most current orbital elements from the NASA Prediction Bulletins are carried on the Celestial BBS, (513) 427-0674, and are updated several times weekly.

Atlantis is on pad LC39B. Viktor Afanas'ev and Musa Manarov continue in orbit aboard the Mir/Kvant/Kvant-2/Kristall/Soyuz TM-11/Progress M-7 complex. The Progress M-6 cargo craft undocked on Mar 15 and reentered. Progress M-7 was launched on Mar 19 and docked on Mar 28 at the third attempt. This is the first time that a Progress has had an aborted docking; it got within 100m on Mar 22 and missed; another attempt failed on Mar 23. The Progress cargo craft is based on the Soyuz design. Kosmos-2136 landed on Mar 20 after a standard 2 week Vostok class recon mission. Kosmos-2137 was launched on Mar 19 by a Kosmos/R-14 rocket into a 449x494 km orbit inclined 65.8 degrees. This orbit marks it as one of a rare class of small spacecraft believed to be doing radar calibration or surveillance work; it is the fourth in a series launched from 1979 onwards. MLF1 Kosmos-1146 1979 Dec 5 444x494x65.9 MLF2 Kosmos-1427 1982 Dec 29 445x499x65.8 MLF3 Kosmos-1615 1984 Dec 22 453x512x65.8 MLF4 Kosmos-2137 1991 Mar 19 449x494x65.8 Kosmos-2138 was launched on Mar 26 by Soyuz from Plesetsk. It is a recon satellite carrying a number of film return capsules and will stay in orbit for 2 months. A Nadezhda navigation/search and rescue satellite was launched by Kosmos/R-14 on Mar 12. The Kospas search and rescue transponder is similar to ones carried on US NOAA weather satellites. Nadezhda satellites launched to date: NE9 Kosmos-1383 1982 Jun 29 (Kospas) 991x1029x83 NE10 Kosmos-1447 1983 Mar 24 (Kospas) 961x1015x83 NE13 Kosmos-1574 1984 Jun 21 (Kospas) 971x1010x83 NE19 Nadezhda 1989 Jul 4 (Kospas) 960x1013x83 NE20 Nadezhda 1990 Feb 27 (Kospas) 938x1003x83 NE22 Nadezhda 1991 Mar 12 (Kospas) 958x1017x83 The 40-th Molniya-3 C-band comsat was launched from Plesetsk on Mar 22. The Molniya launch vehicle is a Soyuz booster with an extra Blok-L fourth stage. ___________________________________ |Current STS status: | |Orbiters | | | |OV-102 Columbia OPF Bay 1 | |OV-103 Discovery OPF Bay 2 | |OV-104 Atlantis LC39B | | | |ML/ET/SRB stacks | | | |ML1/STS-37/ET/OV-104 LC39B | |ML2/STS-39/ET VAB Bay 1 | |ML3/STS-40 VAB Bay 3 | ----------------------------------- 10 years ago: 22-30 Mar 1981 Soyuz-39 carried out a week long mission to the Salyut-6 space station.
