A view of Launch Pad 39B at NASA's Kennedy Space Center in Florida shows space shuttle Endeavour rolling off the pad for the 3.4-mile rollaround to Launch Pad 39A. First motion was at 8:28 a.m. EDT. At right is the open rotating service structure with the Payload Changeout Room and the fixed service structure with the 80-foot-tall lightning mast on top. Endeavour is targeted to launch Nov. 14 on the STS-126 mission. On this 27th mission to the International Space Station, Endeavour will carry the Lightweight Multi-Purpose Experiment Support Structure Carrier and the Multi-Purpose Logistics Module Leonardo that will hold supplies and equipment, including additional crew quarters, additional exercise equipment, spare hardware and equipment for the regenerative life support system.
