CAPE CANAVERAL, Fla. - On Launch Pad 39A at NASA's Kennedy Space Center in Florida, the members of space shuttle Discovery's STS-131 crew continue their emergency exit training in a bunker near the catch nets for the slidewire baskets at the base of the pad. The bunker would provide a safe haven for the astronauts if evacuation of the pad were required. From left are Commander Alan Poindexter; Mission Specialists Rick Mastracchio and Clayton Anderson; Pilot James P. Dutton Jr.; and Mission Specialists Stephanie Wilson, Naoko Yamazaki of the Japan Aerospace Exploration Agency, and Dorothy Metcalf-Lindenburger. The crew members of space shuttle Discovery's STS-131 mission are at Kennedy for training related to their launch dress rehearsal, the Terminal Countdown Demonstration Test. The seven-member crew will deliver the multi-purpose logistics module Leonardo, filled with resupply stowage platforms and racks, to the International Space Station aboard Discovery. Targeted for launch on April 5, STS-131 will be the 33rd shuttle mission to the station and the 131st shuttle mission overall.
