This line of inquiry did not begin until earlier this month--more than three months after the accident--because there were "too many emotions, too many egos," said retired Adm. Harold Gehman, chairman of the Columbia Accident Investigation Board.
Testifying before the Senate Commerce Committee, Gehman said this part of his inquiry Was in its earliest stages, starting just 10 days ago. But Gehman said he already has concluded it is "inconceivable" that NASA would have been unable or unwilling to attempt a rescue for astronaut, s in orbit if senior shuttle managers and administrators had known there was fatal damage to Columbia’s left wing.
Gehman told reporters after the hearing that answers to these important questions could have enormous impact, since they could place in a different context NASA’s decisions against more aggressively checking possible wing damage in the days before Columbia’s fatal return.
Investigators believe breakaway insulating foam damaged part of Columbia’s wing Shortly after liftoff, allowing superheated air to penetrate the wing during its fiery re-entry on Feb. 1 and melt it from the inside.
Among those decisions was the choice by NASA’s senior shuttle managers and administrators to reject offers of satellite images of possible damage to Columbia’s left wing before the accident. The subject dominated the early part of Wednesday’s hearing. Gehman complained that managers and administrators "missed signals" when they rejected those offers for images, a pointedly harsh assessment of the space agency’s inaction during the 16 day shuttle mission.
"We will attempt to pin this issue down in our report, but there were a number of bureaucratic and administrative missed signals here," Gehman told senators. "We’re not quite so happy with the process."
The investigative board already had recommended that NASA push for better coordination between the space agency and military offices in charge of satellites and telescopes. The U. S. National Imagery and Mapping Agency in March agreed to regularly capture detailed satellite images of space shuttles in orbit.
Still, Gehman said it was unclear whether even images from America’s most sophisticated spy satellites might have detected on Columbia’s wing any damage, which Gehman said could have been as small as two inches square. The precise capabilities of such satellites was a sensitive topic during the Senate hearing.

CCTV security systems could soon spot an assault on a bus before it happens, according to a major research project.
The system, part of which has already been tested in laboratory conditions, looks for suspicious behaviour associated with crime. It would be able to send live CCTV pictures to operation rooms, from where controllers would be able to intervene.
The Queens University Belfast team say the software could make a significant impact on crime on transport. Although much of the work is currently at the theoretical stage, they predict that within five years their software will be able to profile people as they board a bus. The system would then compare who it thinks these people are, and what they are doing, with more general data on the bus’s location, time of day and historic crime rates. Once it has sifted this data, it could be able to conclude whether someone is about to commit an assault and send live pictures to controllers.
Dr Paul Miller, head of the research project, said the 15-strong team were still developing initial databases to identify an individual’s gender and body shape. However, the team say the system goes further by then looking for recognised signs of an imminent criminal offence. These signs include someone moving seats shortly before an assault, groups closing in on a passenger sitting alone and people loitering on a double-decker’s stairwell, or close to the driver’s cab.
The system would only alert a controller if the sum of all of these" atomic events" added up to the Drofile of a possible crime. "The system won’t be able to say, ’this is an incident’ —but it will be able to push that video stream to the top of the queue for security analysts [in a control room] to make a decision, "said Dr Miller." Ultimately, most of the events will be benign, with nothing going on. That’s why you still need the human element. "
Dr Miller said that laboratory tests on gender recognition, based on a database of 4,000 faces, had proved successful and the project would move into testing systems on buses over the next year. "Research shows crimes happen when there is an opportunity and no chance of payback," he said. "If a security analyst can directly communicate with the assailant, to tell them they are being watched, it will have a marked effect on the offender. Just one example of this actually happening can have a deterrent effect on the crime rate in an area. /
