Arlington National Cemetery
The Space Shuttle "Challenger" Memorial was dedicated on May 20, 1986, in memory of the crew of flight STS-51-L, who died during launch on January 28, 1986. Transcribed on the back of the stone is the text of the John Gillespie Magee, Jr. poem "High Flight", which was quoted by then President Ronald Reagan when he addressed the disaster. Although many remains were identified and returned to the families for private burial, some were not, and were laid to rest under the marker. Two crew members, Scobee and Smith, are buried in Arlington. On February 1, 2004, NASA Administrator Sean O'Keefe dedicated a similar memorial to those who died when the Shuttle "Columbia" broke apart during reentry on February 1, 2003. Astronauts Laurel Clark, David Brown and Michael Anderson, who were killed in the "Columbia" disaster, are also buried in Arlington.
Space Shuttle Columbia
"Columbia" spent 610 days in the Orbiter Processing Facility (OPF), another 35 days in the Vehicle Assembly Building (VAB), and 105 days on Pad 39A before finally lifting off. "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 flew the next three shuttle missions, while "Columbia" underwent modifications for the first Spacelab mission.
