CAPE CANAVERAL, Fla. – On Launch Pad 39A at NASA's Kennedy Space Center in Florida, STS-119 crew members gather around the slidewire baskets used for emergency egress from the pad. From left are Mission Specialist Steve Swanson, Pilot Tony Antonelli, Mission Specialist Koichi Wakata, Commander Lee Archambault and Mission Specialist John Phillips. Practicing emergency 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.
