NASA Extends Space Shuttle Main Engine Contract

Each space shuttle is powered by three of the sophisticated engines, the world's only reusable rocket engines. During launch, each of the 7,750-pound engines burns liquid hydrogen and liquid oxygen, fed from the shuttle's external tank.

Washington DC (SPX) Aug 03, 2007
NASA has signed a $975 million contract extension with Pratt and Whitney Rocketdyne to maintain the agency's fleet of space shuttle main engines until the orbiter is retired in 2010. The contract began on April 1, 2006. It is scheduled to conclude Sept. 30, 2010. The $975 million contract extension brings the total value of the cost-plus-award/incentive fee contract to slightly more than $2.05 billion.

Pratt and Whitney Rocketdyne supports the Shuttle Propulsion Office at NASA's Marshall Space Flight Center in Huntsville, Ala.; the Space Shuttle Program Office at NASA's Johnson Space Center in Houston; and the Space Operations Mission Directorate at NASA Headquarters in Washington.

The contract includes maintenance and refurbishment of existing shuttle main engines at NASA's Kennedy Space Center, Fla.

Each space shuttle is powered by three of the sophisticated engines, the world's only reusable rocket engines. During launch, each of the 7,750-pound engines burns liquid hydrogen and liquid oxygen, fed from the shuttle's external tank.

Each engine generates approximately 400,000 pounds of thrust, which works with the shuttle's twin solid rocket boosters to power the spacecraft to orbit.

Cabin Leak Threatens US Space Shuttle Launch
Washington (AFP) July 31, 2007
NASA engineers have discovered a leak in space shuttle Endeavour's cabin and are rushing to find its source to prevent a delay in the mission's launch, a US space agency spokesman said Tuesday. The engineers found a small leak over the weekend after they closed the shuttle's hatch to check that the cabin seals properly during a routine check for the August 7 launch, NASA spokesman Kyle Herring told AFP. "You can't launch with a cabin leak," Herring said, adding, however, "At this point there is no delay of the launch."
