NASA RESETS SHUTTLE ENDEAVOUR'S LAUNCH FOR NO EARLIER THAN MAY 2
WASHINGTON -- NASA managers met Friday to discuss the status of space
shuttle Endeavour's launch to the International Space Station. The
launch was postponed because of a heater issue associated with the
shuttle's hydraulic power system. The next launch attempt will be no
earlier than May 2.
The shuttle has three Auxiliary Power Units (APUs) that provide
hydraulic power to steer the vehicle during ascent and entry. NASA
launch commit criteria and flight rules require all three APUs to be
fully operational for launch.
Endeavour's external fuel tank was drained of more than 500,000
gallons of liquid hydrogen and oxygen so engineers can access the
area Saturday and evaluate the issue with APU 1.
