On Launch Pad 39A at NASA's Kennedy Space Center in Florida, workers take photos of the ground umbilical carrier plate's (GUCP) 7-inch quick disconnect, which has been removed from the external fuel tank. A hydrogen gas leak at that location during tanking for space shuttle Discovery's STS-133 mission to the International Space Station caused the launch attempt to be scrubbed Nov. 5. The GUCP will be examined to determine the cause of the hydrogen leak and then repaired. The GUCP is the overboard vent to the pad and the flame stack where the vented hydrogen is burned off. Discovery's next launch attempt is no earlier than Nov. 30 at 4:02 a.m. EST.
