Space Shuttle Columbia (OV-102) was a Space Shuttle orbiter manufactured by Rockwell International and operated by NASA. Named after the first American ship to circumnavigate the upper North American Pacific coast and the female personification of the United States, Columbia was the first of five Space Shuttle orbiters to fly in space, debuting the Space Shuttle launch vehicle on its maiden flight on April 12, 1981 and becoming the first ever spacecraft to be re-used after its first flight when it launched on STS-2 on November 12, 1981. As only the second full-scale orbiter to be manufactured after the Approach and Landing Test vehicle Enterprise, Columbia retained unique external and internal features compared to later orbiters, such as test instrumentation and distinctive black chines. In addition to a heavier aft fuselage and the retention of an internal airlock throughout its lifetime, these made Columbia the heaviest of the five spacefaring orbiters; around 1,000 kilograms (2,200 pounds) heavier than Challenger and 3,600 kilograms (7,900 pounds) heavier than Endeavour when originally constructed. Columbia also carried ejection seats based on those from the SR-71 during its first six flights until 1983, and from 1986 onwards carried an imaging pod on its vertical stabilizer.
During its 22 years of operation, Columbia was flown on 28 missions in the Space Shuttle program, spending over 300 days in space and completing over 4,000 orbits around Earth. NASA's Flagship Orbiter, Columbia often flew flights dedicated to scientific research in orbit following the loss of Challenger in 1986. Columbia was used for eleven of the fifteen flights of Spacelab laboratories, all four United States Microgravity Payload missions, and the only flight of Spacehab's Research Double Module. In 1992, NASA modified Columbia to be able to fly some of the longest missions in the Shuttle Program history using the Extended Duration Orbiter pallet. The pallet was used by the orbiter in thirteen of the pallet's fourteen flights, which aided lengthy stays in orbit for scientific and technological research missions. The longest duration flight of the Shuttle Program, STS-80, was flown with Columbia in 1996, at over 17 days in orbit. Columbia was also used to deploy the first ever satellites into orbit by the Shuttle on STS-5, retrieve the Long Duration Exposure Facility and deploy the Chandra observatory, which was the heaviest payload ever carried by the Space Shuttle. Columbia also carried into space the first female commander of an American spaceflight mission, the first ESA astronaut, the first female astronaut of Indian origin, and the first Israeli astronaut.
At the end of its final flight in February 2003, Columbia disintegrated upon reentry, killing the seven-member crew of STS-107 and destroying most of the scientific payloads aboard. The Columbia Accident Investigation Board convened shortly afterwards concluded that damage sustained to the orbiter's left wing during the launch of STS-107 fatally compromised the vehicle's thermal protection system. The loss of Columbia and its crew led to a refocusing of NASA's human exploration programs and led to the establishment of the Constellation program in 2005 and the eventual retirement of the Space Shuttle program in 2011. Numerous memorials and dedications were made to honor the crew following the disaster; the Columbia Memorial Space Center was opened as a national memorial for the accident, and the Columbia Hills in Mars' Gusev crater, which the Spirit rover explored, were named after the crew. The majority of Columbia's recovered remains are stored at the Kennedy Space Center's Vehicle Assembly Building, though some pieces are on public display at the nearby Visitor Complex.
