The Pegasus barge passes through the haulover canal on the Banana River with its cargo of external tank No. 125. The barge is being towed to the turn basin in the Launch Complex 39 Area where the external tank will be offloaded and moved to the Vehicle Assembly Building. The external tank will be used on space shuttle Atlantis for mission STS-122 targeted for launch on Dec. 6. Photo credit: NASA/Troy Cryder
