CAPE CANAVERAL, Fla. (AP) - NASA has postponed the launch of
space shuttle Discovery because of a gas leak.
The leak of gaseous hydrogen occurred as the launch team was
filling the external fuel tank for liftoff Wednesday night. The
seven astronauts had yet to board the spaceship.
Discovery's flight to the international space station is already
a month late because of concern about hydrogen gas valves in the
engine compartment.
NASA officials say the leak occurred in plumbing outside of the
shuttle and had nothing to do with those valves.
Shuttle officials are now shooting for a launch on Thursday
night.
