KENNEDY SPACE CENTER -- NASA scrubbed the launch of STS-127, the space shuttle Endeavour, this morning at 12:25 a.m. EST. The launch, originally planned for 7:17 a.m., is now pushed back to at least June 17, NASA says.
A leak of gaseous hydrogen from the ground umbilical plate, venting fuel from the external fuel tank was discovered this morning. This is similar to what scrubbed STS-119 in March The mission management team will meet tomorrow at 2 p.m. to discuss the nature of the leak and the next launch opportunity.
The leak requires a 96-hour scrub turnaround, pushing Endeavour past its launch window. The next launch window is June 17.
Fuel is being drained at the moment. NASA will not be able to look further into the causes of the leak for 24 hours, as fuel is inerted and boiled off, a NASA spokesman said.
The crew of STS-127 will remain on site and quarantined, he said.
