The orbiter Endeavour hangs vertically above the transfer aisle of the Vehicle Assembly Building. It will be lifted into the upper levels of the Vehicle Assembly Building , moved laterally over a crossbeam to high bay 1 and stacked with the external tank and solid rocket boosters on the mobile launcher platform. Endeavour will be launched on mission STS-118, its first flight in more than four years. The shuttle has undergone extensive modifications, including the addition of safety upgrades already added to shuttles Discovery and Atlantis. Endeavour also features new hardware, such as the Station-to-Shuttle Power Transfer System that will allow the docked shuttle to draw electrical power from the station and extend its visits to the orbiting lab. Endeavour is targeted for launch on Aug. 7. Photo credit: NASA/Troy Cryder
