KENNEDY SPACE CENTER, FLA. -- The dawn sky over the Atlantic Ocean reveals Space Shuttle Endeavour sitting on Launch Pad 39A. First motion out of the Vehicle Assembly Building was at 8:10 p.m. July 10, and the shuttle was hard down on the pad at 3:02 a.m. July 11. The orbiter access arm is already extended to the orbiter from the fixed service structure. Peering just above the solid rocket booster on the left is the 290-foot-tall water tank. It provides the deluge over the mobile launcher platform for sound suppression during liftoff. Endeavour is scheduled to launch on mission STS-118 on Aug. 7. During the mission, Endeavour will carry into orbit the S5 truss, SPACEHAB module and external stowage platform 3. The mission is the 22nd flight to the International Space Station and will mark the first flight of Mission Specialist Barbara Morgan, the teacher-turned-astronaut whose association with NASA began more than 20 years ago. STS-118 will be the first flight since 2002 for Endeavour, which has undergone extensive modifications, including the addition of safety upgrades already added to orbiters Discovery and Atlantis.
