CONTRACT RELEASE: C08-008

NASA AWARDS EXTERNAL TANK CONTRACT MODIFICATION

WASHINGTON - NASA has signed a $47 5 million contract modification with Lockheed Martin, New Orleans, for space shuttle external fuel tanks The modification aligns and extends all activities associated with the production contract to include final assembly of one tank, partial manufacture of a tank and the acquisition of the component parts for one additional tank to serve as spares

The modification supports the agency's priorities of safely flying the space shuttle, completing construction of the International Space Station and NASA's long-term plan to return astronauts to the moon and beyond

The cost plus award fee/incentive fee contract will conclude Sept 30, 2010, and brings the total value of the contract, awarded in October 2000, to $2 93 billion The contract calls for the delivery of 18 external tanks to NASA

Work will be performed at NASA's Michoud Assembly Facility in New Orleans, NASA's Marshall Space Flight Center in Huntsville, Ala , and NASA's Kennedy Space Center, Fla

Lockheed Martin builds, assembles and tests the space shuttle external tanks for NASA at the Michoud facility The external tank holds the liquid hydrogen fuel and liquid oxygen for the shuttle's three main engines It is the largest single component of the space shuttle and the only part of the shuttle that is not reused At 154 feet tall, the gigantic rust-colored tank is taller than a 15-story building and as wide as a silo, with a diameter of about 27 5 feet During launch, the tank acts as the structural backbone for the shuttle orbiter and the solid rocket boosters attached to it
