In this image, taken June 14, workers on Kennedy Space Center's Launch Pad 39A prepare to remove the 7-inch quick disconnect and flight seal from the Ground Umbilical Carrier Plate, or GUCP, on space shuttle Endeavour's external fuel tank. Teams are removing the hardware to change out seals in the internal connection points. The GUCP is the overboard vent to the pad and the flare stack where the vented hydrogen is burned off. On June 12, a hydrogen leak caused the STS-127 mission to be scrubbed. Endeavour is scheduled to launch on its STS-127 mission on June 17, 2009, at 5:40 a.m. EDT.
