The orbiter Endeavour hangs nearly vertical above the transfer aisle of the Vehicle Assembly Building. It will be lifted into the upper levels of the VAB, moved to high bay 1 and stacked with the e1ternal 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 e1tensive 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 e1tend its visits to the orbiting lab. Endeavour is targeted for launch on Aug. 7. Photo credit: NASA/Charisse Nahser
