Sierra Nevada Corporation Completes Dream Chaser® Milestones for Commercial Crew Integrated Capabilities Program

SPARKS, Nev., April 25, 2013 – Sierra Nevada Corporation’s (SNC) Space Systems has successfully completed two milestones as part of NASA's Commercial Crew Integrated Capability (CCiCap) phase of the agency’s Commercial Crew Program. SNC completed the Program Implementation Review, providing NASA with detailed plans for advancing the Dream Chaser® crew transportation system towards a critical design state. SNC also completed an Integrated System Baseline Review that communicated the post-Preliminary Design Review maturity of the baseline Dream Chaser® orbital crew vehicle, mission systems, ground systems, and United Launch Alliance's Atlas V launch vehicle.

“The successful completion of these milestones resulted in affirmation that the Dream Chaser® Space System design meets its mission requirements as we work towards rebuilding the United States’ capability to fly astronauts into low Earth orbit,” said Jim Voss, vice president of SNC's Space Exploration Systems. “Both CCiCap milestones offered us the opportunity to communicate SNC's detailed development plans, as well as to receive and incorporate NASA's comments and feedback.”

SNC was awarded $212.5 million by NASA in August 2012 and to date has received over $330 million by NASA’s Commercial Crew Program. The funding represents the agency's co-investment in furthering the development of the Dream Chaser® Space System design to carry crew and critical cargo to and from the International Space Station. The Dream Chaser orbital crew vehicle is scheduled to complete its first free flight test in conjunction with NASA's Dryden Flight Research Center at Edwards Air Force Base in Calif., in 2013.
