CAPE CANAVERAL, Fla. -- Technicians prepare space shuttle Discovery's external fuel tank for a tanking test no earlier than Dec. 15 on Launch Pad 39A at NASA's Kennedy Space Center in Florida. During the test, engineers will monitor what happens to 21-foot long, U-shaped aluminum brackets, called stringers, located at the intertank, as well as the newly replaced ground umbilical carrier plate (GUCP), during the loading of cryogenic propellants. Teams already have installed environmental enclosures on the tank, removed foam and prepared the tank's skin for approximately 89 strain gauges and thermocouples. Discovery's first launch attempt for STS-133 was scrubbed in early November due to a hydrogen gas leak at GUCP. The next launch opportunity is no earlier than Feb. 3, 2011.
