Ground Umbilical Carrier Plate Removal Photo Collection

This photo collection shows the work that was done (Wednesday) on the Ground Umbilical Carrier Plate (GUCP), on space shuttle Endeavour’s external fuel tank.

A hydrogen leak at the location during tanking for the STS-127 mission caused the launch attempts to be scrubbed on June 13 and June 17.

The GUCP will be examined to determine the cause of the hydrogen leak and repaired. The GUCP is the overboard vent to the pad and the flame stack where the vented hydrogen is burned off. Endeavour’s next launch attempt is targeted for July 11 at 7:39 p.m. EDT.
