KENNEDY SPACE CENTER, FLA. - External tank No. 118 waits in the Vehicle Assembly Building for a crane to be attached that will raise it to vertical and lifted into high bay 3 for mating with solid rocket boosters stacked there. The tank is designated to fly on mission STS-115 with Atlantis. It will fly with many major safety changes, including the removal of the protuberance air load ramps. The mission will deliver the second port truss segment, the P3/P4 Truss, to attach to the first port truss segment, the P1 Truss, as well as deploy solar array set 2A and 4A. Launch of Space Shuttle Atlantis is scheduled for late August. Photo credit: NASA/Jim Grossmann
