![]() NASA made several technical and organizational changes to subsequent missions, including adding an on-orbit inspection to determine how well the orbiter's thermal protection system (TPS) had endured the ascent, and keeping a designated rescue mission ready in case irreparable damage was found. Construction of the International Space Station (ISS) was paused until flights resumed in July 2005 with STS-114. ![]() When Columbia reentered the atmosphere of Earth, the damage allowed hot atmospheric gases to penetrate the heat shield and destroy the internal wing structure, which caused the orbiter to become unstable and break apart.Īfter the disaster, Space Shuttle flight operations were suspended for more than two years, as they had been after the Challenger disaster. Before reentry, NASA managers had limited the investigation, reasoning that the crew could not have fixed the problem if it had been confirmed. Similar foam shedding had occurred during previous Space Shuttle launches, causing damage that ranged from minor to nearly catastrophic, but some engineers suspected that the damage to Columbia was more serious. The disaster was the second of two fatal accidents in the Space Shuttle program, after the 1986 breakup of Challenger soon after liftoff.ĭuring the STS-107 launch, a piece of the insulative foam broke off from the Space Shuttle external tank and struck the thermal protection system tiles on the orbiter's left wing. The Space Shuttle Columbia disaster was a fatal incident in the United States space program that occurred on February 1, 2003, when the Space Shuttle Columbia disintegrated as it reentered the atmosphere, killing all seven crew members.
