 Space Shuttle Columbia landing, completing STS-80. The mission lasted for 17 days, 15 hours, 53 minutes, and 18 seconds. 

Space Shuttle Columbia (NASA Orbiter Vehicle Designation: OV-102) was the first spaceworthy Space Shuttle in NASA's orbital fleet. First launched on the STS-1 mission, the first of the Space Shuttle program, it completed 27 missions before disintegrating during re-entry on February 1, 2003 near the end of its 28th mission, STS-107, resulting in the deaths of all crew members aboard.

 History

Construction began on Columbia in 1975 at Rockwell International's (formerly North American Aviation/North American Rockwell, now Boeing North America) principal assembly facility in , a suburb of Los Angeles. Columbia was named after the historical poetic name for the United States of America, like the explorer ship of Captain Robert Gray and the Command Module of Apollo 11, the first manned landing on another celestial body. Also, Columbia was the female symbol of the U.S. After construction, the orbiter arrived at Kennedy Space Center on March 25, 1979, to prepare for its first launch. Columbia was originally scheduled to lift off in late 1979, however the launch date was delayed by problems with both the SSME components, as well as the thermal protection system (TPS).[2] On March 19, 1981, during preparations for a ground test, workers were asphyxiated while working in Columbia's nitrogen-purged aft engine compartment, resulting in (variously reported) two or three fatalities.[3][4]

 The first flight of Columbia (STS-1) was commanded by John Young, a Gemini and Apollo veteran who was the ninth person to walk on the Moon in 1972, and piloted by Robert Crippen, a rookie astronaut originally selected to fly on the military's Manned Orbital Laboratory (MOL) spacecraft, but transferred to NASA after its cancellation, and served as a support crew member for the Skylab and Apollo-Soyuz missions.

 Columbia spent 610 days in the Orbiter Processing Facility (OPF), another thirty-five days in the Vehicle Assembly Building (VAB), and 105 days on Pad 39A before finally lifting off.[2] Columbia was successfully launched on April 12, 1981, the 20th anniversary of the first human spaceflight (Vostok 1), and returned on April 14, 1981, after orbiting the Earth 36 times, landing on the dry lakebed runway at Edwards Air Force Base in California. Columbia then undertook three further research missions to test its technical characteristics and performance. Its first operational mission, with a four-man crew, was STS-5, which launched on November 11, 1982. At this point Columbia was joined by Challenger, which performed the next three shuttle missions, while Columbia underwent modifications for the first Spacelab mission.

 In 1983, Columbia, under the command of John Young for his sixth spaceflight, undertook its second operational mission (STS-9), in which the Spacelab science laboratory and a six-person crew was carried, including the first non-American astronaut on a space shuttle, Ulf Merbold. After the flight, Columbia spent 18 months at the Rockwell Palmdale facility beginning in January 1984, undergoing modifications that removed the Orbiter Flight Test hardware and bringing it up to similar specifications as that of its sister orbiters. At that time the shuttle fleet was expanded to include Discovery and Atlantis.

 Columbia returned to space on January 12, 1986, with the launch of STS-61-C. The mission's crew included Dr. Franklin Chang-Diaz, as well as the first sitting member of the House of Representatives to venture into space, Bill Nelson.

 The next shuttle mission was undertaken by Challenger. It was launched on January 28, 1986, ten days after STS-61-C had landed. The mission 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 commanded by Lt. Col. Eileen Collins, the first female Commander of a U.S. spacecraft.
