Tugboats maneuver the Pegasus barge close to the dock in the turn basin near the Vehicle Assembly Building, or VAB, at NASA's Kennedy Space Center in Florida. Pegasus, carrying the 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. 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.
