KENNEDY SPACE CENTER, FLA. -- Space Shuttle Endeavour is on Launch Pad 39A and ready for prelaunch processing after a nearly 7-hour trip from the Vehicle Assembly Building. First motion out of the VAB 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 at left. On top of the structure is the 80-foot-tall lightning mast that helps provide protection from lightning on the pad. The shuttle sits on a mobile launcher platform. Part of the platform and seen below the orbiter's wings are the tail masts, which provide several umbilical connections to the orbiter, including a liquid-oxygen line through one and a liquid-hydrogen line through another. 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.
