STS-51-B was the seventeenth flight of the shuttle program and the seventh for Space Shuttle Challenger. It was the second flight for SpaceLab.
The Space Shuttle is a retired, partially reusable low Earth orbital spacecraft system operated from 1981 to 2011 by the U.S. National Aeronautics and Space Administration (NASA) as part of the Space Shuttle program. Its official program name was Space Transportation System (STS). Five complete Space Shuttle orbiter vehicles were built and flown on a total of 135 missions from 1981 to 2011.
Space Shuttle Challenger (Orbiter Vehicle Designation: OV-099) was the second orbiter of NASA's space shuttle program to be put into service, after Columbia. Challenger was built by Rockwell International's Space Transportation Systems Division, in Downey, California. Its maiden flight, STS-6, began on April 4, 1983. The orbiter was launched and landed nine times before breaking apart 73 seconds into its tenth mission, STS-51-L, on January 28, 1986, resulting in the death of all seven crew members, including a civilian school teacher. It was the first of two shuttles to be destroyed in flight, the other being Columbia, in 2003. The accident led to a two-and-a-half-year grounding of the shuttle fleet; flights resumed in 1988, with STS-26 flown by Discovery. Challenger was replaced by Endeavour, which was built from structural spares ordered by NASA in the construction contracts for Discovery and Atlantis.
