NASA Goes Full Court Press On Hydrogen Leak

Leaky Valve Has Scrubbed Two Endeavour Launch Attempts

Space Shuttle Program teams are working on plans for carrying out a through engineering investigation into the reoccurring hydrogen gas leak that has postponed space shuttle Endeavour's STS-127 mission to the International Space Station until next month.

A leak in the hydrogen venting system outside Endeavour's external fuel tank postponed Endeavour's launches Saturday and Wednesday. The leak occurred in the attaching point to the external tank and the vent line at the Ground Umbilical Carrier Plate, or GUCP.

Endeavour's seven astronauts are spending the rest of the week with family and friends. They returned to NASA's Johnson Space Center in Houston yesterday morning and will resume their mission training next week.

At NASA Kennedy Space Center's Launch Pad 39A, technicians moved the rotating service structure back around Endeavour Thursday morning. The structure provides access to the shuttle and protection from the weather.

Endeavour's next launch attempt is targeted for July 11 at 7:39 p.m. EDT.
