The world of human space flight paused-first to mourn, then to discover what had happened. Bush in a national address, 14:04 EST, February 1, 2003 NASA refers to this most rare and catastrophic of events as an LOCV-" Loss of Crew and Vehicle." FrozenĬolumbia is lost. The control room was sealed off, and each flight controller began carefully preserving his or her console's data.Ĭolumbia was gone, and all seven of her crew had been killed. It was an acknowledgement that the worst had happened the mission was now in "contingency" mode. Finally, at 9:12 Eastern Time, re-entry Flight Director LeRoy Cain keyed his communications loop and called out a rarely heard order: " Lock the doors." Advertisement Controllers continued to hope that they were merely looking at instrumentation failures, even as evidence mounted that a catastrophic event had taken place. Sixteen days later, as Columbia re-entered the atmosphere, superheated plasma entered the orbiter's structure through the hole in the wing and the shuttle began to disintegrate.Īt Mission Control in Houston, the flight controllers monitoring Columbia's descent began to notice erratic telemetry readings coming from the shuttle, and then all voice and data contact with the orbiter was lost. In reality, the impact shattered at least one of the crucial reinforced carbon-carbon heat shield panels that lined the edge of the wing, leaving a large hole in the brittle ceramic material. Instead, NASA's Debris Assessment Team mathematically modeled the foam strike but could not reach any definitive conclusions about the state of the shuttle's wing. Foam strikes during launch were not uncommon events, and shuttle program managers elected not to take on-orbit images of Columbia to visually assess any potential damage. Only after the shuttle was orbiting Earth did NASA's launch imagery review reveal that the wing had been hit. Columbia continued to climb toward orbit. Just under a minute and a half later, at 81.7 seconds after launch, a chunk of insulating foam tore free from the orange external tank and smashed into the leading edge of the orbiter's left wing at a relative velocity of at least 400 miles per hour (640 km/h). Columbia Accident Investigation Board ReportĪt 10:39 Eastern Standard Time on January 16, 2003, space shuttle Columbia lifted off from pad 39A at the Kennedy Space Center in Florida. It is important to note at the outset that Columbia broke up during a phase of flight that, given the current design of the Orbiter, offered no possibility of crew survival. The conquest of space is worth the risk of life. We are in a risky business, and we hope that if anything happens to us, it will not delay the program. But just as it is human nature to look to the future and wonder what might be, so too is it in our nature to look at the past and wonder, “what if?” Today, on the twentieth anniversary of the event, Ars is re-publishing our detailed 2014 examination of the biggest Columbia "what if" of all: what if NASA had recognized the damage to the orbiter while the mission was still in progress? Could anything have been done to save the crew? February 1, 2023: One of the most tragic events in the history of space exploration is the loss of the space shuttle Columbia and all seven of her crew on February 1, 2003-a tragedy made worse because it didn’t have to happen.
