Summary
STS-61-B launched on a Lockheed Space Operations Company Space Shuttle from Launch Complex 39A, Kennedy Space Center, FL, USA on November 27, 1985. It was Lockheed Space Operations Company's 14th launch, 9th this year and humanity's 3,017th orbital launch attempt. It was the 23rd Space Shuttle flight and the 9th this year. The payload was bound for low Earth orbit (LEO). Atlantis (STS 61-B), one of 8 catalogued objects, reached a 360 × 366 km orbit inclined 28.5°. 7 crew members flew: Rodolfo Neri Vela, Brewster H. Shaw, Bryan D. O'Connor, Mary L. Cleave, Jerry L. Ross, Sherwood C. Spring and Charles D. Walker. The spacecraft was Space Shuttle Atlantis (OV-104). 8 objects from this launch are catalogued, 5 of them payloads.

Spacecraft
Space Shuttle Atlantis (OV-104)
Space Shuttle Atlantis (Orbiter Vehicle Designation: OV‑104) is a Space Shuttle orbiter vehicle belonging to the National Aeronautics and Space Administration (NASA), the spaceflight and space exploration agency of the United States. Constructed by the Rockwell International company in Southern California and delivered to the Kennedy Space Center in Eastern Florida in April 1985, Atlantis is the fourth operational and the second-to-last Space Shuttle built. Its maiden flight was STS-51-J from 3 to 7 October 1985. Atlantis embarked on its 33rd and final mission, also the final mission of a space shuttle, STS-135, on 8 July 2011. STS-134 by Endeavour was expected to be the final flight before STS-135 was authorized in October 2010. STS-135 took advantage of the processing for the STS-335 Launch On Need mission that would have been necessary if STS-134's crew became stranded in orbit. Atlantis landed for the final time at the Kennedy Space Center on 21 July 2011. By the end of its final mission, Atlantis had orbited the Earth a total of 4,848 times, traveling nearly 126,000,000 mi (203,000,000 km) or more than 525 times the distance from the Earth to the Moon.
- Destination: Low Earth Orbit
- Mission length: 6 days 21 hours
Space Shuttle Atlantis successfully landed at Edwards Air Force Base after this mission.

About this launch
STS-61-B was the twenty-third space shuttle mission and the second for the Space Shuttle Atlantis. The shuttle was launched for Kennedy Space Center and the shuttle deployed three communicates satellites. It also tested techniques for constructing structures in orbit. This mission marked the quickest turnaround of a shuttle, just 54 days elapsed beetween this launch and Atlantis' previous mission.
