Space Shuttle Columbia exploded while it was returning to Earth on Feb. 1, 2003.
The seven astronauts aboard were killed.
Columbia had launched Jan. 16, 2003. While in space the astronauts were performing science experiments 24 hours a day in two shifts.
During launch, a piece of foam insulation broke off from the propellant tank and hit the edge of the shuttle’s left wing. That damage was determined to be the cause of the explosion. Heat shield panels on the wing were damaged.
According to space.com, in 2008, NASA released a crew survival report that determined, “The astronauts probably survived the initial breakup of Columbia, but lost consciousness in seconds after the cabin lost pressure and then died as it disintegrated.”
The crew members were: Michael Anderson, payload commander; David Brown, mission specialist; Kalpana Chawla, mission specialist; Laurel Clark, mission specialist; William McCool, shuttle pilot; Rick Husband, shuttle commander; and Ilan Ramon, payload specialist.
Debris and remains of the astronauts were found in more than 2,000 locations in Texas, Arkansas and Louisiana.
