NASA says Columbia crew had no chance to survive

CAPE CANAVERAL, Florida (Reuters) - Astronauts on the shuttle Columbia were trying to regain control of their craft before it broke apart in 2003, but there was no chance of surviving the accident, a NASA report said on Tuesday.

From the crew's perspective, the shift from what appeared to be a normal descent on February 1, 2003, into disaster happened so fast that the astronauts didn't even have time to close the visors on their helmets.

Columbia broke apart about 12 miles over Texas as it headed for landing at the Kennedy Space Center. The cause of the accident was traced to a hole in one of the shuttle's wings, which was hit by a piece of falling foam insulation during launch 16 days earlier.

Seven astronauts, including Israel's first astronaut Ilan Ramon, were killed when superheated atmospheric gases blasted inside the breach like a blow torch, melting the ship's structure.

The crew cabin broke away from the ship and started spinning rapidly. Analysis of the wreckage indicated the crew members had flipped cockpit switches in response to alarms that were sounding. The astronauts had also reset the shuttle's autopilot system, the report said.

"We have evidence from some of the switch positions that the crew was trying very hard to regain control. We're talking about a very brief time in a crisis situation," said NASA's deputy associate administrator, Wayne Hale.

But rapid depressurization caused the Columbia crew to lose consciousness, and medical findings show that they could not have recovered, said the report, which took four years to compile.

"This report confirms that although the valiant Columbia crew tried every possible way to maintain control of their vehicle, the accident was not ultimately survivable," said Hale, who oversaw the shuttle program during its return to flight after the accident.
