Thermal Analysis Shows Hot Plasma Possible in Columbia Left Wheel Well Area
Preliminary analysis by a NASA working group this week indicates that the
temperature indications seen in Columbia's left wheel well during entry
would require the presence of plasma (super heated gas surrounding the
orbiter during entry.)
Heat transfer through the structure as from a missing tile would not be
sufficient to cause the temperature indications seen in the last minutes
Additional analysis is underway, looking at various scenarios in which a
breach of some type, allowing plasma into the wheel well area or elsewhere
in the wing, could occur.
Other flight data including gear position indicators and drag information
does not support the scenario of an early deployment of the left gear.
The search continues for possible debris from Columbia in the western
U.S., but as of early Thursday, no debris further west than Ft. Worth,
Texas has been confirmed as Shuttle-related.
