On Saturday, Adm. Hal Gehman, chairman of the Columbia Accident
Investigation Board, announced the appointment of Dr. Sheila E. Widnall as
the newest member of the board. Dr. Widnall, former Secretary of the Air
Force, is an expert in aircraft turbulence and spiraling airflows.

As
the search for Space Shuttle Columbia debris continues, NASA working
groups and the independent Columbia Accident Investigation Board, or CAIB,
are poring over flight data that was downlinked by the orbiter during its
last minutes.
Preliminary analysis of the data indicates that plasma was present
in the vehicle's left wheel well during its final moments, the CAIB announced Thursday.
Plasma is a super-heated gas that surrounds the orbiter during re-entry.
The
CAIB said heat transfer through the structure, such as might be
caused by a missing tile, would not be sufficient to cause the temperature
indications seen in the last minutes of flight.
By analyzing other flight data -- including landing gear position
indicators and drag information -- the board also concluded that it is
unlikely the left landing gear was deployed early.
More than 2,500 federal, state and local employees continue to
search for orbiter debris in East Texas and Louisiana. Some of the recovered
pieces have already found their way to the primary investigation site at the
Kennedy Space Center, Fla., or KSC. The first two truckloads of debris arrived
at KSC on Wednesday.
Some
search teams are looking for pieces along Columbia's
flight path west of Fort Worth. So far, no debris has been found farther
west than Granbury, Texas, about 64 kilometers (40 miles) southwest of
Fort Worth. Other teams -- including employees of the Environmental Protection
Agency, the Civil Air Patrol and the Federal Emergency Management Agency --
are searching east and south of Fort Worth.
U.S. Navy divers and equipment may also be brought in to search
the waters of area lakes, including Toledo Bend and the Sam Rayburn reservoir.
Eyewitnesses reported seeing debris enter those lakes on Feb. 1.

Investigators are now working in the Reusable Launch Vehicle Hangar at KSC.
They will now begin the process of reconstructing Columbia, laying out the
pieces relative to one another as they were positioned on the shuttle.
Members
of the Columbia Accident Investigation Board, or
CAIB, conducted an orientation tour of KSC facilities Wednesday.
They viewed the processing locations currently holding NASA's three
remaining orbiters -- Atlantis, Endeavour and Discovery.
KSC officials briefed them about shuttle ground processing.
Also on Wednesday, NASA Administrator Sean O'Keefe addressed a
joint congressional hearing into the Columbia accident.
He responded to questions about the independence of the CAIB.
"The Board has taken over hardware and software releases
of NASA so that NASA cannot alter anything unless the Board approves.
NASA has already begun to honor document requests from the Board, and has
also supplied additional documents to the Board which were not requested
that we believe may be helpful to their work."
O'Keefe also talked about NASA's future.
"We have an opportunity here and now to learn
from this loss, and renew the boundless spirit of exploration present at
NASA's beginning. We will do this by being accountable to the American
people for our failings and, we hope, credible and compelling in pursuit
of research, exploration and inspiration for future generations."

reports:
The first two truckloads of Space Shuttle Columbia debris were expected to
arrive at Kennedy Space Center, Fla., or KSC, on Wednesday. They departed
from Barksdale Air Force Base, La., Tuesday. Search teams have recovered
more than 1,600 pieces of debris so far, tagging them for identification
and delivering them to field collection sites in East Texas. The collected
items are then loaded onto trucks and transported to KSC -- Columbia's
intended destination on Feb. 1 when it broke up in the skies over Texas.
Some of the
accident investigators are working at the collection sites, while others
are already at KSC, analyzing the recovered pieces to determine a cause
for the accident.
NASA Administrator Sean O'Keefe announced Monday that future
information about the Space Shuttle Columbia accident will be released at
a pace directed by the Columbia Accident Investigation Board, or CAIB.
NASA will continue to release information periodically as it becomes available,
but "we will defer to the CAIB to set the pace of discussions of how the
investigation itself is progressing," O'Keefe said.
NASA's role in the investigation is to help determine the cause
of the accident, find solutions to the problem and return to safe flight
operations as soon as possible.

During a news conference Monday, NASA Administrator Sean O'Keefe announced
that future information about the Space Shuttle Columbia accident will be
released at a pace directed by the Columbia Accident Investigation Board,
or CAIB. NASA will continue to release information periodically as it
becomes available, but "we will defer to the CAIB to set the pace of
discussions of how the investigation itself is progressing," O'Keefe said.
"We intend
to fully support and ensure the Board has independence and objectivity to
proceed as its members feel appropriate," Administrator O'Keefe said.
The NASA
Inspector General has been an observer on the ground from the beginning,
helping to ensure the independence and objectivity of the CAIB under the
terms of the Inspector General Act.
NASA's role in the investigation is to help determine the cause of the accident, find
solutions to the problem and return to safe flight operations as soon as
possible.
Debris collection continues in East Texas. Approximately 12,000 pieces have been
found so far. Search teams are tagging the debris and delivering it to
Barksdale Air Force Base, La. The first truckload of debris is expected to
depart Barksdale today, bound for the Kennedy Space Center, Fla.
Investigators there will analyze the recovered pieces, hoping to determine
the cause of the accident.
