The testing of the liquid hydrogen fill and drain valve in shuttle Discovery’s main propulsion system is complete. The valve and its position indicator both operated normally during yesterday’s testing. And all leak checks were within specification.
The evaluation of the low-level hydrogen leak detected in a tail service mast on the mobile launcher platform on Launch Pad 39A following Tuesday's launch scrub is complete, and no leaks were detected.
All the test data will be brought to the mission management team for review at the noon EDT meeting. Mission managers also are scheduled to meet at 2:15 p.m. to give the “Go - No Go” for tanking.
If Discovery gets the “Go”, tanking commentary on NASA TV will begin at 2:45 p.m. and fueling operations will start at approximately 3 p.m. Launch commentary will begin tonight at 7 p.m.
Discovery's seven astronauts are sleeping and will wake up for their launch day preps at 1:30 p.m.
