Viewed from across the turn basin in the Launch Complex 39 Area at NASA's Kennedy Space Center in Florida, the Pegasus barge is maneuvered up to the dock. In the background at left is the Vehicle Assembly Building. The barge holds the external fuel tank, ET- 132, designated for space shuttle Discovery on the STS-128 mission. The tank will be offloaded and transported to a high bay in the VAB for checkout. On the STS-128 mission, Discovery will carry science and storage racks to the International Space Station. Launch of Discovery is targeted for Aug. 6. Photo credit: NASA/Troy Cryder
