In NASA's Vehicle Assembly Building, the redesigned external fuel tank that will launch Space Shuttle Atlantis on the next shuttle mission, STS-115, is suspended above the transfer aisle where it will be raised to a vertical position. Once it is raised, the tank will be moved into a checkout cell for further work. The tank, designated ET-118, will fly with many major safety changes, including the removal of the protuberance air load ramps. Photo credit: NASA/George Shelton
