In the RLV Hangar, Congressman Dave Weldon (left) listens to Steve Altemus, Space Shuttle test director. Weldon is visiting the site where pieces of Columbia debris are being examined and stored. Third from left is Center Director Roy Bridges. Workers 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.
