"We've had reports there are pieces on the ground in California and Arizona," Michael Kostelnik, an associate administrator of the National Aeronautics and Space Administration told reporters here. He said team of experts had been dispatched to various sites in those states to examine the wreckage but cautioned that it was "not clear what the material is" at this point. The move follows media reports that a radio-astronomer from the California Institute of Technology saw what appeared to be "debris shedding" from Columbia as it streaked over the state. The San Francisco Chronicle quoted Anthony Beasley, of Caltech's Owens Valley Radio Observatory, as saying that the shuttle had "a sparkle effect" as it flew over and that he saw a bright piece separate. The potential discovery is seen as important for establishing a credible timeline of the fiery disintegration last Saturday of Columbia and the deaths of all its seven astronauts, according to space flight experts. Such a timeline could help engineers pinpoint the problem that that has led to a sharp rise in temperatures in the spacecraft's left wing and on the left side of the fuselage and, ultimately, the shuttle's disintegration as it headed for landing at the Kennedy Space Center in Florida. "It would be important to see the material early in the sequence," Kostelnik said. Received on Tue 04 Feb 2003 07:36:31 PM PST |
