These pictures show the
punctures in the coolant tubes in the right main engine of Columbia
which caused a small hydrogen leak during the Shuttle's climb
to orbit on July 23.
These
close up views show the denting and rupturing of the three coolant
tubes in the nozzle of Columbia's right main engine, likely caused
by foreign object debris during the Shuttle's launch July 23.
Following
the landing of Space Shuttle Columbia on July 27, this close-up
view shows what appear to be three small holes in the liquid hydrogen
tubes inside the nozzle on main engine No. 3. Engineers will examine
the engine to determine if a possible hydrogen leak occurred during
the STS-93 launch on July 23.
