CAPE CANAVERAL, Fla. – The sun rises over Launch Pad 39A at NASA's Kennedy Space Center in Florida to a cloud-filled sky and operations under way to secure space shuttle Discovery to the pad. Discovery's first motion on its 3.4-mile trip from the Vehicle Assembly Building was at 11:58 p.m. EST March 2. The shuttle was secured on the pad at 6:48 a.m. March 3. Rollout is a significant milestone in launch processing activities. The seven-member STS-131 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.
