Space Shuttle Columbia was the first space shuttle designed and built by NASA.
Space Shuttle Columbia was the first spaceworthy Space Shuttle in NASA's orbital fleet. Space Shuttle Columbia's first mission, STS-1, lasted from April 12 to April 14, 1981. On February 1, 2003, Space Shuttle Columbia disintegrated during re-entry over Texas, on its 28th mission. All seven crew members aboard Space Shuttle Columbia perished.
History of Space Shuttle Columbia.
Construction began on Columbia in 1975 primarily in Palmdale, California. Columbia was named after the Boston-based sloop Columbia captained by American Robert Gray, who explored the Pacific Northwest and became the first American vessel to circumnavigate the world; the name also honored Columbia, the command module of Apollo 11. After construction, the orbiter arrived at John F. Kennedy Space Center on March 25, 1979, to prepare for its first launch. On March 19, 1981, during preparations for a ground test, five workers were asphyxiated during a Nitrogen purge, resulting in two deaths.
The first flight of Columbia (STS-1) was commanded by John Young (a space veteran from the Gemini and Apollo eras) and piloted by Robert Crippen, who had never been in space before, but who served as a support crew member for the Skylab missions and Apollo-Soyuz. It launched on April 12, 1981, and returned on April 14, 1981, after orbiting the earth 36 times. 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.
In 1983, Columbia undertook its second operational mission (STS-9), this time with six astronauts, including the first non-American astronaut on a space shuttle, Ulf Merbold. Columbia was not used for the next three years, during which 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 R. 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 shortly after launch. In the aftermath NASA's shuttle timetable was disrupted, and Columbia was not used again until 1988 (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.
Space Shuttle Columbia: Prototype orbiter.
Columbia was roughly 8,000 lb. heavier than subsequent orbiters such as Endeavour, which were of a slightly different design, and had benefitted from advancements in materials technology. In part this was due to heavier wing and fuselage spars, the weight of early test instrumentation that remained fitted to the avionics suite, and an internal airlock that was not fitted to the other shuttles. Despite refinements to the launcher's thermal protection system and other enhancements, Columbia would never weigh as little unloaded as the orbiters in the fleet. The next-oldest shuttle, Challenger, was also relatively heavy, although 2,200 lb. lighter than Columbia.
Externally, Columbia was the only orbiter in the fleet that had an all-tile thermal protection system (TPS), although this was later modified to incorporate nomex felt insulation blankets on the fuselage and upper wing surfaces. The work was performed during Columbia's first retrofitting and the post-Challenger stand-down. Also unique to Columbia were the black "chines" on the upper surfaces of the shuttle's forward wing. These black areas were added because the first shuttle's designers did not know how reentry heating would affect the craft's upper wing surfaces.
Until its last refit, Columbia was the only operational orbiter with wing markings consisting of an American flag on the left wing and the letters "USA" on the right. Challenger, Discovery, Atlantis, and Endeavour all until 1998 bore markings consisting of the letters "USA" afore an American flag on the left wing, and the pre-1998 NASA "worm" logo afore the respective orbiter's name on the right wing. From its last refit to its destruction, Columbia bore markings identical to those of its sister orbiters - the NASA "meatball" logo on the left wing and the American flag afore the "Columbia" designation on the right; Columbia's distinctive wing "chines" remained.
Another unique external feature, termed the "SILTS" pod, was located on the top of Columbia's tailfin, and was installed after STS-9 to acquire infrared and other thermal data. Though the pod's equipment was removed after initial tests, NASA decided to leave it in place, mainly to save costs, along with the agency's plans to use it for future experiments. The tailfin was later modified to incorporate the drag chute first used on Endeavour in 1992.
Internally, Columbia was originally fitted with Lockheed-Martin-built ejection seats identical to those found on the SR-71 Blackbird. These seats were active on the initial series of orbital test flights, but were deactivated after STS-4 and were removed entirely after STS-9. Columbia was also the only orbiter not delivered with heads-up displays for the pilot and copilot, although these were incorporated after STS-9. Like its sister ships, Columbia was eventually retrofitted (at its last refit) with the new MEDS "glass cockpit" display and lightweight seats. Unlike the other orbiters, Columbia retained an internal airlock, but was not fitted to accept the external airlock and docking adapter needed for flights to the International Space Station. This retention of an internal airlock allowed NASA to use Columbia for the STS-109 Hubble Space Telescope servicing mission, along with the Spacehab double module used on STS-107. If Columbia had not been destroyed, it would have been fitted with the external airlock/docking adapter for mission STS-118, an International Space Station assembly mission, in November 2003.
After the STS-118 mission, Columbia’s career would have started to wind down. The shuttle was planned to service the Hubble Space Telescope two more times, once in 2004, and again in 2005, but no more missions were planned for it again until 2009 when, on STS-144, it would retrieve the Hubble Space Telescope from orbit and bring it back to Earth.
Space Shuttle Columbia Flights.
Space Shuttle Columbia flew 28 flights, spent 300.74-days in space, completed 4,808 orbits, and flew 125,204,911 miles in total, including its final mission. It is the only spaceworthy shuttle to have never visited either the Russian Space Station Mir or the International Space Station while those stations have been in operation.

On its final mission, Columbia carried a crew of seven astronauts. They were Rick Husband (commander), Willie McCool (pilot), Michael P. Anderson, Laurel B. Clark, and David M. Brown, Israeli astronaut Ilan Ramon, and Kalpana Chawla.
On the morning of February 1, 2003, the shuttle re-entered the atmosphere after a 16-day scientific mission. NASA lost radio contact at about 0900 EST, only minutes before the expected 0916 landing at Kennedy Space Center in Florida. Video recordings show the craft breaking up in flames over Texas, at an altitude of approximately 39 miles (63 km) and a speed of 12,500 mph (5.6 km/s).
In the months following the tragedy, NASA scientists determined that a hole was punctured in the leading edge on one of Columbia's wings, made of a carbon-carbon composite. The hole had formed when a piece of insulating foam from the external fuel tank peeled off during the launch 16 days earlier, puncturing the edge of the wing. Hot gases, inaccurately described in initial reports as plasma, penetrated the interior of the wing, destroying the support structure and causing the rest of the shuttle to break apart during the intense heat of re-entry.
Forensic analysis of the debris was conducted jointly with the Materials Science department of Lehigh University. The collected debris of the vessel is currently stored on the 16th floor of the Vehicle Assembly Building at the Kennedy Space Center; recovered items are occasionally loaned for research into the hypersonic flight regime. Former NASA Administrator Sean O'Keefe vowed that Columbia will not be sealed away as the debris from the Challenger was. The debris from Challenger is permanently entombed in two Minuteman missile silos at Cape Canaveral Air Force Station.
