NASA managers are expected to make a final decision by this afternoon about whether to launch space shuttle Endeavour on Wednesday, June 17 or wait until later in the week.
Technicians at NASA's Kennedy Space Center are working to fix a leak associated with the gaseous hydrogen venting system outside Endeavour's external fuel tank. The leak postponed Endeavour's Saturday morning scheduled launch to the International Space Station. Teams on Kennedy’s Launch Pad 39A are in the process of changing out internal seals in the Ground Umbilical Carrier Plate, or GUCP, which is attached to the external tank. The vent line runs from the GUCP, away from the launch pad to a "flare stack" where excess hydrogen is safely burned off.
Managers met Sunday afternoon to evaluate how repairs are going and assess when Endeavour's next launch attempt will be. The earliest the shuttle could be ready for liftoff is June 17, however there is a conflict on that date with the scheduled launch of NASA's Lunar Reconnaissance Orbiter/Lunar Crater Observation and Sensing Satellite from Cape Canaveral Air Force Station, Fla.
NASA managers are looking to maximize launch opportunities this week for both the shuttle and the LRO/LCROSS missions. If there are no issues with Endeavour’s repair work, the shuttle would attempt to launch on June 17 and LRO/LCROSS would have launch opportunities on June 19 and 20. If Endeavour doesn’t launch on June 17 and LRO/LCROSS launches on that day, the shuttle could make a launch attempt on June 20.
Endeavour's leak is similar to what happened during the first launch attempt of space shuttle Discovery's STS-119 mission in March. Technicians are using the same repair method, which led to Discovery's successful launch on its next attempt.

STS-127 Mission Overview
The 16-day mission will feature five spacewalks and complete construction of the Japan Aerospace Exploration Agency's Kibo laboratory. Astronauts will attach a platform to the outside of the Japanese module that will allow experiments to be exposed to space.
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.
