NASA Still Unsure How To Inspect Shuttles In-Flight
Planned March Flight Faces Delays
POSTED: 5:52 p.m. EDT May 19, 2004
NASA is still struggling to find a way to inspect and repair any potentially deadly space shuttle gashes in orbit.
It's a hurdle that could prevent shuttle flights from taking off again next March as planned.
The former astronaut heading the return-to-flight task force said the biggest challenge involves a 50-foot inspection boom. He said unless the boom problem is solved quickly -- or an alternative found -- a spring launch may have to be delayed.
Spacewalkers could be used instead of the boom, but at extra risk to the crew.
NASA scrapped the first scheduled post-Columbia launch earlier this year to give it more time to work out a solution.
Columbia shattered over Texas on Feb. 1, 2003, killing all seven astronauts aboard.
It is believed that a piece of foam broke off from a fuel tank during launch, damaging the leading edge of one of the shuttle's wings. That hole could have allowed super-hot gasses inside the wing as it re-entered Earth's atmosphere.
Cameras has recorded the foam striking the shuttle, but there was no way to inspect the shuttle when it was in orbit.
