Columbia Breaks Apart: Seven Astronauts Die in Reentry

Eighty-two seconds into launch, a piece of insulating foam the size of a briefcase broke off Columbia’s external tank and struck the leading edge of the left wing at roughly 500 miles per hour. Sixteen days later, on February 1, 2003, superheated atmospheric gases poured through the resulting breach as the shuttle reentered Earth’s atmosphere, tearing the orbiter apart over Texas and Louisiana and killing all seven crew members. NASA engineers had actually spotted the foam strike on launch footage and spent days debating whether it posed a threat. Three separate requests for satellite imagery of the wing were made by lower-level engineers, all of which were either declined or not forwarded up the chain of command. Program managers concluded the foam could not have caused serious damage, partly because similar foam strikes had occurred on previous missions without catastrophic failure. The Columbia Accident Investigation Board would later call this reasoning a textbook case of "normalization of deviance." The crew, commanded by Rick Husband and including payload commander Michael Anderson, mission specialists David Brown, Kalpana Chawla, and Laurel Clark, pilot William McCool, and payload specialist Ilan Ramon of Israel, had spent sixteen days conducting scientific experiments in orbit. At 8:44 a.m. Eastern Time, mission control lost contact. Debris rained across a corridor stretching from Dallas to western Louisiana. The investigation led to a two-and-a-half-year grounding of the shuttle fleet and sweeping changes to NASA’s safety culture and management structure. The disaster also accelerated the decision to retire the shuttle program entirely, which NASA completed in 2011 after 135 missions. Columbia was the second shuttle lost, twenty years after Challenger. Both tragedies shared a root cause: institutional pressure to maintain launch schedules overriding engineering concerns about known risks.
