sts-61b

The Satcom series was a family of communications satellites originally developed and operated by RCA American Communications (RCA Americom). Satcom was one of the early geostationary satellites; the first were the Syncom series, in 1964. The first Satcom satellite, Satcom 1, was launched on December 13, 1975. The last satellite, Satcom K2, was placed into orbit on November 27, 1985 and was de-orbited in February 2002. Satcom was first superseded and then replaced by the GE series of satellites.

STS-61-B was NASA's 23rd Space Shuttle mission, and its second using Space Shuttle Atlantis. The shuttle was launched from Kennedy Space Center, Florida, on 26 November 1985. During STS-61-B, the shuttle crew deployed three communications satellites, and tested techniques of constructing structures in orbit. Atlantis landed at Edwards Air Force Base, California, at 16:33 EST on 3 December 1985, after 6 days and 21 hours in orbit.
STS-61-B marked the quickest turnaround of a Shuttle orbiter from launch to launch in history – just 54 days elapsed between Atlantis' launch on STS-51-J and launch on STS-61-B. The mission was also notable for carrying the first Mexican astronaut, Rodolfo Neri Vela.
