Space Shuttle Columbia disaster

This image from NASA video shot by Shuttle Mission Specialist Laurel Clark shows Mission Specialists Kalpana Chawla, left, and Commander Rick Husband on the flight deck of the Space Shuttle Columbia shortly before reentry, Feb. 1, 2003, while in space. The 13-minute video was found in the wreckage of the Space Shuttle Columbia near Palestine, Texas five days after the Shuttle broke apart. NASA says the plasma gas seen in the video is normal on all shuttle landings. The tape begins after the de-orbit engine burn and shows the crew preparing to land.
