STS-61-B
STS-61-B (formerly STS-31) 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. This record for turn around between two flights of the same orbital space vehicle was only beaten in July 2020 by SpaceX. The mission was also notable for carrying the first Mexican astronaut, Rodolfo Neri Vela. This was also "Atlantis"' second and final mission to launch before the Space Shuttle "Challenger" disaster in 1986, which would ground the shuttle fleet for two and a half years; "Atlantis" would not fly again until STS-27, which launched on December 2, 1988, roughly three years later.
