KSC-2009-1279

CAPE CANAVERAL, Fla. – Following the simulated launch countdown on Launch Pad 39A at NASA's Kennedy Space Center in Florida, STS-119 crew members are in the slidewire basket they would use during an emergency egress. The slidewire basket could propel them to a landing area below, if needed. The practice egress is part of the prelaunch preparation known as Terminal Countdown Demonstration Test. The TCDT also includes equipment familiarization. Discovery is targeted to launch on the STS-119 mission Feb. 12. During the 14-day mission, the crew will install the S6 truss segment and solar arrays to the starboard side of the International Space Station, completing the station's truss, or backbone.
