CAPE CANAVERAL - NASA
started to take fully assembled shuttle Atlantis apart at Kennedy Space Center
on Wednesday, while plans are on hold to send another external fuel tank back
to its production plant in New Orleans.
Ripple effects from
Hurricane Katrina raised serious doubts about the agency's ability to launch
its next mission in March.
Up to 70 percent of the
people who work at a shuttle external tank manufacturing plant in New Orleans
had their homes damaged or destroyed when Katrina swept ashore this week, NASA
officials said.
Its storm surge swamped the
Michoud Assembly Facility with as much as 2 feet of water. Electrical power and
communications were knocked out. Water service was interrupted.
The Lockheed Martin factory
will remain closed until at least Tuesday, but it might take several weeks to
restore power, communications and other utilities. It's also uncertain how soon
workers will be able to return.
Plans to ship three tanks
-- including the one for NASA's next mission -- back to Michoud for
retrofitting are on indefinite hold.
The situation makes it
increasingly unlikely that NASA will be able to launch its next mission as
planned in March. The next window of opportunity doesn't open until May. But
NASA officials say it's too early to tell whether storm damage will trigger
further delay.
"They're looking at
all sorts of possibilities, and it's much too early to determine how this is
all going to fall out," KSC spokesman Bruce Buckingham said. "Our
prime concern is the employees and their situation in the aftermath of the
storm."
NASA's second post-Columbia
test flight was pushed back to March from September to give engineers time to
solve continuing problems with external tank foam insulation.
Future shuttle flights are
on hold until NASA determines why a large piece of foam fell off Discovery's
tank two minutes after a July 26 launch, barely missing the shuttle's right
wing. A similar chunk of falling foam caused the February 2003 Columbia
disaster.
A NASA investigation team
had been staging its work from Michoud. Operations are now working out of the
Marshall Space Flight Center in Huntsville, Ala.
The 15-story tank for
NASA's next mission will be returned to the 52-story KSC Vehicle Assembly
Building from Port Canaveral.
Loaded onto a covered
barge, it began a trip back to Michoud last week but since has been sheltered
at Port Canaveral to avoid the storm. Now, it's unclear when the tank will be
shipped, Buckingham said.
