On Launch Pad 39A at NASA's Kennedy Space Center in Florida, workers prepare to begin removing the quick disconnect from the ground umbilical carrier plate (GUCP) on space shuttle Discovery's external fuel tank. A hydrogen gas leak at that location during tanking for the 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 targeted for no earlier than Nov. 30 at 4:02 a.m. EST.
