CAPE CANAVERAL, Fla. - At NASA's Kennedy Space Center in Florida, the payload canister containing the multi-purpose logistics module Leonardo, standing vertically on a transporter, arrives at Launch Pad 39A. The canister next will be lifted into the pad's payload changout room. Located on the pad's rotating service structure, the room is an enclosed, environmentally controlled area that supports payload delivery and servicing at the pad and attaches to the shuttle's cargo bay for vertical payload installation. The contents of the canister, including Leonardo, is set to be transferred into space shuttle Discovery's cargo bay on March 24. The seven-member STS-131 crew will deliver Leonardo, filled with resupply stowage platforms and racks, to the International Space Station. STS-131 will be the 33rd shuttle mission to the station and the 131st shuttle mission overall. Launch is targeted for April 5.
