Crews Begin Removing Ground Umbilical Carrier Plate

At NASA's Kennedy Space Center in Florida, crews began removing the plate that attaches a gaseous hydrogen vent line to space shuttle Endeavour's external fuel tank. Hydrogen leaks in the area of the Ground Umbilical Carrier Plate, or GUCP, postponed Endeavour's launch attempts June 13 and 17, delaying its 16-day flight to the International Space Station. The vent line leading from the external tank away from Launch Pad 39A to the "flame stack," where excess hydrogen gas is burned off during fueling, was disconnected over night.
The repairs will be confirmed by a "tanking test" within the next week, in which Endeavour's external tank will be filled with liquid hydrogen and liquid oxygen, just as it is before launch. If the repairs are successful, Endeavour's next launch attempt will be targeted for July 11 at 7:39 p.m. EDT.
At NASA's Johnson Space Center in Houston, the STS-127 mission astronauts will catch up on administrative work and review spacewalk procedures today.
