English: CAPE CANAVERAL, Fla. – On Launch Pad 39A at NASA's Kennedy Space Center in Florida, the pad's White Room, which provides workers and astronauts an entry point to a shuttle's crew compartment, is moved into place against space shuttle Discovery. 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.
