Jonathan's Space Report No. 136 1992 Dec 8 ------------------------------------------------------------------------------ Space Shuttle Discovery was launched at 1324 UTC on Dec 2 into a 369 x 379 km x 57 deg orbit. At 1918 UTC the DoD-1 satellite was deployed. On Dec 3 the orbit was lowered to 317 x 331 km; on Dec 4 an attempt to deploy the ODERACS satellites failed due to electrical problems. Landing is scheduled for Dec 9. STS-53 is the 15th flight of Discovery. This is the 8th Shuttle flight in 1992, a record surpassed only by the 9 flights in 1985. More impressive, however, is NASA's success at meeting target launch dates. Since the delay to STS-39 in early 1991, there have been no major delays to the manifested missions, and every countdown this year has resulted in a launch, with the exception of the first STS-45 countdown which was scrubbed due to bad weather, delaying the mission by one day. Although we must expect scheduling problems in the future, up to and including loss of another orbiter, it does seem that NASA has ridden up the learning curve and can now operate this reusable piloted spacecraft on a schedule whose reliability is at least comparable, say, with unpiloted expendable rockets like Delta. STS-53 Mission Specialist Mike Clifford is the first of the 1990 astronaut group to fly in space; the last of the 1987 group astronauts made their first flight on STS-47. Things have improved a lot since the days when astronauts had to wait over a decade for their first flight! (See table below; group 5 was the first to feel the post-Apollo slump; group 9 the first to be delayed by the Challenger accident. This table ignores the effects of resignations prior to first flight).

A Gorizont C-band comsat was launched by Proton from Baykonur on Nov 27 for the Russian Ministry of Communications. A Molniya-3 elliptical orbit TV relay satellite was launched from Plestesk on Dec 2. The Molniya launch vehicle is a Soyuz with an additional Blok-L fourth stage. A Titan 4 launch vehicle, possibly a 404 variant, was orbited from Space Launch Complex 4-East at Vandenberg AFB on Nov 28. The USA-86 payload is most likely an Advanced Crystal imaging recon satellite, replacing the KH-11/Crystal launched in 1987. Arianespace carried out its seventh launch of the year on Dec 1, using the Ariane 42P variant to place Space Communications Corp. of Japan's Superbird A1 satellite into orbit. The Space Systems/Loral satellite replaces Superbird A, which failed in orbit due to ground controller error. Launches: Date Payload Rocket From Nov 23 Mak-2 - Mir 1986-17GX Nov 24 0420?
