Workers prepare to offload external tank 134 from the Pegasus barge docked in the turn basin near the Vehicle Assembly Building, or VAB, at NASA's Kennedy Space Center in Florida. Pegasus 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 Pegasus docks in the turn basin, the fuel tank will be offloaded and transported into the VAB.

ET-134 will be used to launch space shuttle Endeavour on the STS-130 mission to the International Space Station. Launch is targeted for Feb. 4, 2010. For information on the components of the space shuttle and the STS-130 mission, visit http://www.nasa.gov/shuttle. Photo credit: NASA/Jack Pfaller
