Space Shuttle Columbia and ended in disaster 73 seconds after launch. In the aftermath NASA's shuttle timetable was disrupted, and "Columbia" was not flown again until 1989 (on STS-28), after which it resumed normal service as part of the shuttle fleet. STS-93, launched on July 23, 1999, was the first U.S. space mission with a female commander, Lt. Col. Eileen Collins. This mission deployed the Chandra X-ray Observatory. "Columbia"'s final successful mission was STS-109, the fourth servicing mission for the Hubble Space Telescope.

The first of four orbital test flights occurred in 1981, leading to operational flights beginning in 1982, all launched from the Kennedy Space Center, Florida. The system was retired from service
