On February 1, 2003, the Space Shuttle Columbia disintegrated upon re-entry to the Earth over parts of Texas and Louisiana during STS-107, resulting in the deaths of all seven astronauts. The incident resulted from a piece of foam insulation that fell off during launch, which struck the shuttle, creating a hole that allowed hot gases to penetrate the shuttle during re-entry. In the aftermath of the disaster, the space shuttle program was suspended for 29 months as NASA investigated the incident and made plans to prevent future tragedies.
