Space Shuttle Columbia disaster Space Shuttle Columbia disaster On February 1, 2003, the Space Shuttle "Columbia" disintegrated upon reentering Earth's atmosphere, killing all seven crew members. The disaster was the second fatal accident in the Space Shuttle program after Space Shuttle "Challenger", which broke apart and killed the seven-member crew 73 seconds after liftoff in 1986. During the launch of STS-107, "Columbia"'s 28th mission, a piece of foam insulation broke off from the Space Shuttle external tank and struck the left wing of the orbiter. A few previous shuttle launches had seen damage ranging from minor to nearly catastrophic from foam shedding, but some
Space Shuttle in the lower atmosphere. After the foam burned away during re-entry, the heat caused a pressure buildup in the remaining liquid oxygen and hydrogen until the tank exploded. This ensured that any pieces that fell back to Earth were small. The Shuttle was monitored throughout its ascent for short range tracking (10 seconds before liftoff through 57 seconds after), medium range (7 seconds before liftoff through 110 seconds after) and long range (7 seconds before liftoff through 165 seconds after). Short range cameras included 22 16mm cameras on the Mobile Launch Platform and 8 16mm on the Fixed Service Structure,
