Launch Scrubbed after Slight GH2 Leak
Wed, 11 Mar 2009 03:34:19 PM EDT
NASA officials scrubbed Wednesday’s attempt at 2:37 EDT to launch space shuttle Discovery after a slight leak was detected in a gaseous hydrogen (GH2) vent line. The vent line is at the intertank region of the external tank and is the overboard vent to the pad and the flare stack where the vented hydrogen is burned off. The launch team is resetting to preserve the option of attempting a Thursday night liftoff at 8:54 p.m. EDT depending on what repairs are needed and what managers decide. The Mission Management Team is meeting at 5 p.m. today to discuss the issue.
