CAPE CANAVERAL, Fla. - At the foot of Launch Pad 39A at NASA's Kennedy Space Center in Florida, STS-131 Pilot James P. Dutton Jr. hops out of a slidewire basket during training on the emergency exit system at the pad. Looking on are Mission Specialists Naoko Yamazaki of the Japan Aerospace Exploration Agency, at left, and Dorothy Metcalf-Lindenburger. The system includes 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 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.
