In the RLV Hangar, Space Shuttle Test Director Steve Altemus (left) shows former astronauts Jim Lovell (center) and Wally Schirra (right) a piece of debris from Columbia. The latter two visited several sites around the Center, encouraging workers to help get the space program "back on its feet." The RLV Hangar is where Columbia debris is being collected and examined as part of the investigation into the tragedy that claimed the orbiter and lives of seven astronauts returning from mission STS-107.
