CAPE CANAVERAL, Fla. -- At NASA’s Kennedy Space Center in Florida, External Fuel Tank-122 is suspended vertically over the transfer aisle of the Vehicle Assembly Building as it is lifted toward a test cell. ET-122, the Space Shuttle Program's last external fuel tank was delivered to Kennedy's Turn Basin from NASA’s Michoud Assembly Facility in New Orleans aboard the Pegasus Barge. After testing, ET-122 eventually will be attached to space shuttle Endeavour for the STS-134 mission to the International Space Station targeted to launch February, 2011.

KENNEDY SPACE CENTER, FLA. — In the transfer aisle of the Vehicle Assembly Building at NASA's Kennedy Space Center, space shuttle Atlantis is raised into a vertical position. Atlantis will next be lifted into high bay 3 and mated with the external tank and solid rocket boosters designated for mission STS-122, already secured atop a mobile launcher platform. On this mission, Atlantis will deliver the Columbus module to the International Space Station. The European Space Agency's largest contribution to the station, Columbus is a multifunctional, pressurized laboratory that will be permanently attached to U.S. Node 2, called Harmony. The module is approximately 23 feet long and 15 feet wide, allowing it to hold 10 large racks of experiments. The laboratory will expand the research facilities aboard the station, providing crew members and scientists from around the world the ability to conduct a variety of experiments in the physical, materials and life sciences. Mission STS-122 is targeted for launch on Dec. 6. Photo credit: NASA/George Shelton

CAPE CANAVERAL, Fla. -- The Space Shuttle Program's last external fuel tank, ET-122, has been moved inside the Vehicle Assembly Building at NASA's Kennedy Space Center in Florida. The tank traveled 900 miles by sea from NASA's Michoud Assembly Facility in New Orleans to Kennedy's Turn Basin aboard the Pegasus Barge. The tank eventually will be attached to space shuttle Endeavour for the STS-134 mission to the International Space Station. STS-134, targeted to launch in Feb. 2011, 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.

CAPE CANAVERAL, Fla. -- Boaters watch as Freedom Star, one of NASA's solid rocket booster retrieval ships, pulls the Space Shuttle Program's last external fuel tank, ET-122, toward NASA's Kennedy Space Center in Florida. The tank traveled 900 miles by sea from NASA's Michoud Assembly Facility in New Orleans aboard the Pegasus Barge. After reaching the Turn Basin at Kennedy, the tank will be offloaded and moved to the Vehicle Assembly Building where it eventually will be attached to space shuttle Endeavour for the STS-134 mission to the International Space Station.

LOUISIANA -- In Gulfport, La., tugboats are preparing the Pegasus Barge carrying the Space Shuttle Program's last external fuel tank, ET-122, for connection to Freedom Star, NASA's solid rocket booster retrieval ship. The tank will travel 900 miles by sea to NASA's Kennedy Space Center in Florida before being offloaded and moved to Kennedy's Vehicle Assembly Building. There it will be integrated to space shuttle Endeavour for the STS-134 mission to the International Space Station. 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.
