CAPE CANAVERAL, Fla. – A shuttle training aircraft drops for touchdown on the Shuttle Landing Facility runway at NASA's Kennedy Space Center in Florida. STS-119 Commander Lee Archambault and Pilot Tony Antonelli are practicing shuttle landings as part of the Terminal Countdown Demonstration Test activities. The TCDT includes equipment familiarization and a simulated launch countdown. The STA is a Grumman American Aviation-built Gulf Stream II jet that was modified to simulate a shuttle’s cockpit, motion and visual cues, and handling qualities. In flight, the aircraft duplicates the shuttle’s atmospheric descent trajectory from approximately 35,000 feet to landing. The crew of space shuttle Discovery is targeted to launch on the STS-119 mission Feb. 12. During Discovery's 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.
