NASA was forced to postpone the launch of space shuttle Endeavour on Wednesday for the second time after a problem with a hydrogen gas leak surfaced again while the ship was being fueled for flight.
An identical problem delayed a launch attempt on Saturday. Technicians had replaced seals in a hydrogen vent line in hopes of fixing the leak. The next opportunity to launch Endeavour will be on July 11 because of because of temperature constraints related to the International Space Station’s orbit.
“We’re going to step back and figure out what the problem is and go fix it,” said deputy shuttle program manager LeRoy Cain. “Obviously we have something here we didn’t understand as well as we thought we may have.”
Next up: Thursday June 18’s launch attempt for LRO/LCROSS at 5:12 p.m., 5:22 p.m. or 5:32 p.m. EDT. (9:12. 9:22 or 9:32 GMT)
