NASA has postponed the launch of space shuttle Endeavour's STS-127 mission because of another hydrogen leak
NASA officials have rescheduled the launch of space shuttle Endeavour's STS-127 mission for 5:40 a.m. EDT on Wednesday, June 17. The national space agency postponed Endeavour's original June 13 liftoff date due to concerns over a leak associated with the gaseous hydrogen venting system outside the shuttle's external fuel tank.
NASA said that it has decided to postpone the launch of the launch of
Endeavour and mission STS-127 because of “a leak associated with the
gaseous hydrogen venting system”. A similar problem was found in March
before the launch of Discovery, which caused a mission delay of more
than a month.
