CONTRACT RELEASE: C07-21

NASA MODIFIES ORION CREW EXPLORATION VEHICLE CONTRACT

WASHINGTON - NASA has modified its contract with Lockheed Martin Corp of Littleton, Colo , to design, test and build the Orion crew exploration vehicle

The updated contract contains three significant changes Two years have been added to the design phase Two test flights of Orion's launch abort system have been added And production of a pressurized cargo carrier for the International Space Station has been deleted from the initial design phase

NASA continues work to ensure a smooth transition from the Space Shuttle Program to the Constellation Program This is demonstrated in a fourth element of the contract modification that provides for use of surplus raw materials, such as aluminum-lithium ingots now used in the construction of space shuttle fuel tanks, for Orion

"NASA and Lockheed have been working together as a team during the past six months to iron out many critical design and schedule details," said Skip Hatfield, manager the Orion Project at NASA's Johnson Space Center in Houston "This contract update will synchronize our spending plan with the rest of the Constellation Program "

NASA awarded the Orion prime contract to Lockheed Martin Corp on Aug 31, 2006 At that time, the development portion of the contract was valued at $3 9 billion with a period of performance through December 2011 This contract modification, in the amount of $385 million, brings the total value to approximately $4 3 billion and adjusts the development period of performance through December 2013

This update is the result of a NASA request for engineering change proposal issued on Dec 15, 2006 Lockheed Martin's proposal was received March 7, 2007 The contract modification was signed April 20

The modification reflects continuing progress on Orion's development, including program formulation and systems assessments addressing the rocket, ground infrastructure and all other elements necessary for a successful first launch The period of performance now matches the evolving NASA budget landscape

"The Orion team has made some critical decisions that will maximize the performance and flexibility of this spacecraft," said Jeff Hanley, manager of the Constellation Program at Johnson "This spacecraft will be a cornerstone of America's human exploration of the solar system by a new generation of explorers, and these changes and additional tests will ensure that it is robust enough to accomplish its missions "

Meanwhile, work progresses as planned on the contract NASA and Lockheed Martin have completed Orion's systems requirements review and are moving toward a systems design review scheduled in August
