CAPE CANAVERAL, Fla. -- This panoramic image shows tug boats maneuvering the Pegasus Barge carrying the Space Shuttle Program's last external fuel tank, ET-122, through the Turn Basin at NASA's Kennedy Space Center in Florida. Once docked, the tank will be offloaded from the barge and transported to the Vehicle Assembly Building (VAB). NASA's Liberty Star solid rocket booster retrieval ship is seen (left) docked at the Turn Basin. The tank traveled 900 miles by sea, carried in the barge, from NASA's Michoud Assembly Facility in New Orleans. Once inside the VAB, it eventually will be attached to space shuttle Endeavour for the STS-134 mission to the International Space Station targeted to launch Feb. 2011. STS-134 currently is scheduled to be the last mission in the shuttle program. The tank, which is the largest element of the space shuttle stack, was damaged during Hurricane Katrina in August 2005 and restored to flight configuration by Lockheed Martin Space Systems Company employees.
