English: CAPE CANAVERAL, Fla. - At Launch Pad 39A at NASA's Kennedy Space Center in Florida, from left, STS-131 Mission Specialists Clayton Anderson, Naoko Yamazaki of the Japan Aerospace Exploration Agency, and Stephanie Wilson practice pad emergency evacuation procedures inside a slidewire basket. Evacuation from the pad's 195-foot level is made possible by seven baskets suspended from seven slidewires that extend from the fixed service structure to a landing zone 1,200 feet west of the pad. The crew members of space shuttle Discovery's STS-131 mission are participating in 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.
