NASA Completes Key Review of Orion Spacecraft

NASA has established arequirements baseline for its planned new Orion crew exploration vehicle, bringing America's next human spacecraft a step closer to construction, the space agency says.

The Orion project completed its system requirements review in cooperation with its prime contractor, Lockheed Martin, March 1, NASA says. The review marked the first major milestone in the Orion engineering process and provided the foundation for design, development, construction and safe operation of the spacecraft that will carry explorers to Earth orbit, tothe moon, and eventually to Mars, the space agency says. The detailed requirements established in this review will serve as the basis for ongoing design analysis work and systems testing.

"This is a significant step in the development of a space transportation system that will expand our horizons to include other worlds," says Skip Hatfield, Orion Project manager at NASA's Johnson Space Center in Houston.

The Orion review followed an overall review of requirements for the Constellation program that was completed in November. Similar reviews are planned later this spring for ground and mission operations systems that will support Constellation launch systems and space flight operations ground infrastructure.

"We have now completed program-wide launch vehicle and human spacecraft system requirements reviews," says Constellation Program Manager Jeff Hanley. "These are important pieces of a management and engineering puzzle that will allow us to accomplish the goal of putting humans back on the moon."

The Orion requirements data set was reviewed by agency and contractor scientists and engineers from across the country. More than 1,700 topicscovering all aspects of vehicle performance, design and qualification werediscussed during the course of the formal review.

Once all project-level reviews are complete, the Constellation Program will hold another full review to update baseline requirements. A lunar architecture systems review of equipment associated with surface exploration and science activities on the moon is expected in the spring of 2009.
