A crew access hatch(front center) from the space shuttle Columbia is just one of several pieces of debris being cataloged by NASA (news - web sites) officials Barksdale Air Force Base in Louisiana February 10, 2003. NASA officials said on Monday they have identified part of Columbia's left wing, a critical discovery because that is where heat spiked just before the spacecraft disintegrated on February 1.
