CAPE CANAVERAL, Fla. (AP) - NASA is removing some parts from the
shuttle that is out on the launch pad in hopes of plugging a gas leak and launching Discovery to the international space station on Sunday.
Discovery was supposed to blast off Wednesday night with a crew of seven and one final set of solar wings for the space station. But hydrogen gas began leaking as the shuttle was being fueled, and
NASA called everything off.
The leak occurred near the line that vents hydrogen gas out of the external fuel tank. On Thursday, workers removed the quick-disconnect unit at that location and a pair of seals. They will replace the parts Friday.
A NASA spokesman says shuttle managers have "high confidence"
that all work can be done in time to launch in the evening.
