The Pegasus barge is towed into the turn basin in the Launch Complex 39 Area. In the foreground are the U.S. flag and launch countdown clock near the NASA News Center. The barge's cargo is the external tank prepared for mission STS-118 by the Michoud Assembly Facility near New Orleans. After docking, the tank will eventually be offloaded and moved to the Vehicle Assembly Building.. Photo credit: Jack Pfaller
