Towed by a tugboat, the Pegasus barge passes through the open bridge in the Banana River on its way to the turn basin in the Launch Complex 39 Area at NASA's Kennedy Space Center. The barge is carrying the external tank for space shuttle Endeavour's STS-123 mission. After offloading, the tank will be transported to the Vehicle Assembly Building. Endeavour is targeted for launch to the International Space Station on Feb. 14. Photo credit: NASA/Jim Grossmann
