GUCP Repair Work Concluding

[Inside KSC News Feeds]

Technicians are putting the last touches on the Ground Umbilical Carrier Plate, or GUCP, in preparation for tomorrow’s leak test involving the full tanking of the external tank with super-cold liquid hydrogen and liquid oxygen. The tanking is slated to begin at 7 a.m. EDT Wednesday. Leak checks at an ambient temperature were completed Monday. The GUCP leaked on two prior launch attempts for the STS-127 mission when the cryogenic propellants were loaded into space shuttle Endeavour’s external tank. The Endeavour astronauts are completing administrative work today and will take T-38 training jet flights to El Paso, Texas. Also, technicians removed a stuck work light knob in space shuttle Atlantis that wedged between a window and dashboard during the STS-125mission. Technicians pressurized Atlantis before pulling the knob out, clearing the way for the window to be inspected.
