A closeup of space shuttle Endeavour after its arrival on Launch Pad 39A at NASA's Kennedy Space Center in Florida. Traveling from the Vehicle Assembly Building, the shuttle took nearly 12 hours on the journey as technicians stopped several times to clear mud from the crawler's treads and bearings caused by the waterlogged crawlerway. 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. 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
