An alligator basks in the sun on the bank of the Banana River near NASA's Kennedy Space Center in Florida. It is witness to the passage of the Pegasus barge through the Banana River toward the turn basin near the Vehicle Assembly Building, or VAB, at NASA's Kennedy Space Center in Florida. Pegasus, carrying external tank 130, arrived in Florida after an ocean voyage towed by a solid rocket booster retrieval ship from NASA's Michoud Assembly Facility near New Orleans. After the Pegasus docks, the fuel tank will be offloaded and transported to the VAB. External tank 130 is the one designated for space shuttle Endeavour on the STS-127 mission targeted for launch on May 15. Photo credit: NASA/Troy Cryder
