NASA astronauts John Young and Mark Kelly inspect Columbia debris arriving at KSC from the collection point at Barksdale Air Force Base, Shreveport, La. The debris is being collected at the RLV Hangar near the Shuttle Landing Facility. Workers there will attempt to reconstruct the orbiter as part of the ongoing investigation of the accident that destroyed the Columbia and claimed the lives of seven astronauts as they returned to Earth after a 16-day research mission, STS-107.
