CAPE CANAVERAL, Fla. –Sitting on top of the mobile launcher platform and propelled by the crawler-transporter, space shuttle Discovery rolls up Launch Pad 39A at NASA's Kennedy Space Center in Florida after a nearly 12-hour journey from the Vehicle Assembly Building. First motion out of the VAB was at 2:07 a.m. EDT Aug. 4. Rollout was delayed approximately 2 hours due to lightning in the area. The rollout was slower than usual as technicians stopped several times to clear mud from the crawler's treads and bearings caused by the waterlogged crawlerway. The drying mud of the crawlerway is evident in the foreground. Discovery's 13-day flight will deliver a new crew member and 33,000 pounds of equipment to the International Space Station. The equipment includes science and storage racks, a freezer to store research samples, a new sleeping compartment and the COLBERT treadmill. Launch of Discovery on its STS-128 mission is targeted for late August. Photo credit: NASA/Troy Cryder
