Mission Control Center even told the crew that there was “absolutely no concern for entry” because the phenomenon had been seen before. The event that doomed Columbia was noticed during the second day of the ill-fated mission, upon reviewing launch camera photography. The organizational failures that led NASA to downplay or dismiss all accident precursors as “acceptable risks” are well documented in the board’s report. According to the investigation board, damage caused by debris occurred on every space shuttle flight, and STS-107 was the seventh time that a release of foam from the bipod ramp was recorded. What caused the release of a piece of foam during ascent was not an “unforeseen and unplanned event or circumstance,” as the definition of “accident” would imply the external tank was defective by design, and the phenomenon of debris shedding was well known. and Soviet space programs - the Columbia disaster was not an accident at all. The impact caused the breach in the wing’s leading edge, creating the conditions for the re-entry breakup.Īs in all previous fatalities in human spaceflight - both in U.S. The board determined that the leading cause of the accident was the impact of the shuttle’s left wing with a piece of foam coming off the external tank’s bipod fitting 81.7 seconds after launch. The Columbia Accident Investigation Board was convened by NASA to investigate the event. Destruction of the crew module took place over a period of 24 seconds, beginning at an altitude of 42,672 meters and ending at 32,000 meters, leaving the crew with no chance of survival. The heat, reaching behind the thermal protection system, resulted in thermal degradation of structural properties of the left wing, causing destruction of the insulation that protected the leading edge support structure and melting the aluminum wing spar. The shuttle was destroyed upon re-entry by a flux of super-heated air, estimated to be about 2,760 degrees Celsius, coming through a breach in the reinforced carbon-carbon left wing’s leading edge. 1 marks the 10th anniversary of one of the most tragic events in human spaceflight: the loss of Space Shuttle Columbia and its crew. "Columbia, we're studying the debris for the effects of hypersonic re-entry on materials.Feb. "Challenger, we buried it and moved on," Mike Leinbach, the launch director for the STS-107 Columbia mission, told WUSA. However, unlike the Challenger investigation, which has been put to rest, the Columbia tragedy is still being studied. During the same week, decades prior, the Challenger space shuttle mission ended in tragedy, killing all seven crew members. They determined there was a thermal breach in Columbia's left wing, which caused it to have structural failure. The FBI, in collaboration with other local and national agencies, and of course NASA, worked together to determine what caused the crash.

Then sometimes you'd find a piece the size of a Volkswagen Beetle," Hillman said, according to an FBI report.Ībout 84,000 pieces in total were discovered, which makes up about 40 percent of the spacecraft, according to. "Sometimes you would find a piece that was two inches by two inches. Michael Hillman, an FBI Dallas special agent, led the Hazardous Evidence Response Team that helped clean up after the incident. #NASARemembers /0O0q5dPsop- NASA History Office February 1, 2018 Fifteen years ago #OTD, Feb 1, 2003, at 8:59 am EST Space Shuttle Columbia broke up on reentry killing the crew of mission STS-107 - Rick Husband, Willie McCool, Michael Anderson, Kalpana Chawla, David Brown, Laurel Clark, and Ilan Ramon.
