NASA officials announced plans in Monday to launch space shuttle Endeavor on Wednesday after delaying the Saturday’s initial launch due to a hydrogen leak.
NASA is expected to make a final decision this afternoon on whether or not the shuttle will launch on Wednesday, June 17th or if they should delay for another week.
Meanwhile, the repairs to the shuttle’s external fuel tank would be completed by 6:00 a.m. (1000 GMT) Monday, officials said. The leak was similar to one from the first launch attempt of space shuttle Discovery’s STS-119 mission in March. Technicians are using the same repair method, NASA said.
The STS-127 crew members are Commander Mark Polansky, Pilot Doug Hurley and Mission Specialists Dave Wolf, Christopher Cassidy, Tom Marshburn, Tim Kopra and Canadian Space Agency astronaut Julie Payette. Kopra will join the space station crew and replace Japanese astronaut Koichi Wakata. Wakata will return to Earth on Endeavour to conclude a three-month stay at the station.
The new launch schedule interferes with previous plans to launch the Lunar Reconnaissance Orbiter (LRO) on Wednesday. NASA said it would be pushing the probe’s launch back to Friday.
