NASA postponed the launch of the space shuttle Endeavour early Wednesday because of a liquid hydrogen leak. It is the same type of leak that caused the postponement of an earlier launch from Kennedy Space Center in Florida. On June 13, a leak was detected in the gaseous hydrogen venting system outside the shuttle’s external fuel tank, the space agency said
The space shuttle Discovery lifted off Sunday evening on a mission to the international space station, where Discovery will deliver supplies needed to expand the station’s crew to six people. The shuttle launched at 7:43 p.m
The space shuttle Discovery is on pace for a Sunday launch after NASA engineers repaired a leaky gas venting system, officials said Saturday. The leak had canceled a planned launch on Wednesday. NASA hopes the seven-member crew can take off around 7:40 p.m.
