Kennedy Space Center
On February 1, 2003, "Columbia" and her crew of seven were lost during re-entry over Texas during the STS-107 mission (the 113th shuttle flight); a vehicle breakup triggered by damage sustained during launch from Pad 39A on January 16, when a piece of foam insulation from the orbiter's external fuel tank struck the orbiter's left wing. During reentry, the damage created a hole allowing hot gases to melt the wing structure. Like the "Challenger" disaster, the resulting investigation and modifications interrupted shuttle flight operations at KSC for more than two years until the STS-114 launch on July 26, 2005.
Columbia (supercontinent)
Columbia began to fragment about 1.5–1.35 Ga, associated with continental rifting along the western margin of Laurentia (Belt-Purcell Supergroup), eastern India (Mahanadi and the Godavari), southern margin of Baltica (Telemark Supergroup), southeastern margin of Siberia (Riphean aulacogens), northwestern margin of South Africa (Kalahari Copper Belt), and northern margin of the North China Block (Zhaertai-Bayan Obo Belt).
