UPDATE: NASA now says they will try for a new launch on Nov. 30th. Florida Today talks to the shuttle launch director:
"We want to do the right thing for this vehicle," said Mike Leinbach, the shuttle launch director. "We were presenting an option to the program that might have gotten to Monday, but we all know in our hearts the right thing to do is to take this slowly, understand this issue (and) go fix it."
The launch of the shuttle Discovery was scrubbed this morning after NASA detected a leak of dangerous gaseous hydrogen.
According to the AP, NASA might try to launch this Monday but the timing is complex.
Florida Today explains:
NASA had said the agency needed to launch Discovery by Sunday or delay until a window that opens Dec. 1 and closes after Dec. 5. But they also were looking at whether Monday might be a possibility.
Up until now, NASA has said the sun angle on the International Space Station between Monday and Nov. 23 will be such that the outpost could not generate enough power, and the shuttle could not dispel enough heat, for docked operations.
A similar kind of leak delayed launches twice in 2009. Weather delayed yesterday's original launch date.
When the shuttle finally goes into orbit, it will be Discovery's 39th -- and final -- mission.
