SNC PR Louisville, CO – June 24, 2011 – Sierra Nevada Space Systems (SNC) has announced completion of two significant milestones as part of the Commercial Crew Development Round 2 (CCDev2) Program.  SNC is building the Dream Chaser, a Space Shuttle-like human spacecraft for NASA to provide astronaut transport to the International Space Station (ISS).

“The first milestone completed under the CCDev2 program was a major step in the development of the spacecraft – a Systems Requirement Review (SRR), where SNC validated their requirements based on NASA’s draft Commercial Crew Program Requirements,” SNC Space Systems head Mark Sirangelo said. “The SRR was successfully completed on June 1, 2011 with participation by NASA and SNC industry partners.  All the requirements were approved and will be used to guide the design of the Dream Chaser to ensure that it meets the pending NASA certification requirements.

“Our fast-paced SNC Dream Chaser development program completed its second milestone only two weeks after Milestone 1.  This milestone was a review of the selection of the improved airfoil fin shape to be used on the Dream Chaser.  This new fin will improve the handling qualities of the spacecraft as it flies in the atmosphere on return from space to a gentle runway landing.  Wind tunnel testing and computational fluid dynamics analyses were used to complete the fin selection milestone work.”

Jim Voss, Vice President of SNC’s Space Exploration added, “These were important milestones in our program, whose successful accomplishment sets the stage for completing significant work during the CCDev2 Program. NASA aerodynamicists, engineers, and managers from the Commercial Crew Program evaluated the work and participated as active participants in the review.  The rapid development enabled by our partnership with NASA and the world class space companies on our team will ensure that our Nation retains its leadership in human spaceflight.”

Under the CCDev2 program, SNC will conduct multiple spacecraft hardware milestones and other development activities over the next year, culminating in a system-level Preliminary Design Review (PDR) and preparation for atmospheric flight test of the Dream Chaser.  As the only company under contract to NASA for development of a Shuttle-like spacecraft, SNC is positioned to quickly restore US capability to transport humans to the ISS after the Space Shuttle retires and to support other human spaceflight markets in low Earth orbit.

About The Dream Chaser

The Dream Chaser is a lifting body spacecraft based on former NASA design, the HL-20 crew vehicle, and carries with it a strong development heritage.  It will launch on an existing launch vehicle and will have on-board propulsion utilizing SNC’s proprietary hybrid rocket motor technology.  The Dream Chaser, which is now under full production, is a piloted or autonomous spacecraft which provides safe, reliable, and cost effective transport of up to seven crew members or a combination of people and cargo to low earth orbit and returning them safely to the Earth without excessive deceleration or landing forces.  Risk to deconditioned crew and delicate science experiment return samples is minimized through a low G landing on a runway.  The combination of NASA heritage and proven technology will enable SNC’s unique space transportation system to effectively and reliably carry crew and cargo to orbital destinations.
