SPARKS, Nev. (Mynews4.com & KRNV) – Sierra Nevada Corporation has announced the successful completion of the second Dream Chaser Space System Integrated Systems Safety Analysis Review, marking the company’s completion of NASA’s Commercial Crew Integrated Capability initiative Milestone six. This critical safety review evaluated the Dream Chaser spacecraft, the launch vehicle, vehicle integration and the ground and mission systems, which comprise the entire DCSS.
Milestone six represents a major step forward in the maturation of the system's safety and reliability analysis, which is critical to achieving a safe and effective design of the DCSS. During the milestone review, SNC provided NASA with significant and detailed systems safety analysis products, including hazard analysis and failure tolerance analysis of the entire DCSS.
Vice-President Mark N. Sirangelo said that SNC's Dream Team is making significant strides to prepare the Dream Chaser Space System for its first orbital flight. “The completion of this safety milestone is a vital program and developmental achievement that advances the program considerably. By successfully passing two critical cornerstone safety milestones in 2013, we have established a path for the Dream Chaser to safely transport U.S. astronauts to and from low-Earth orbit.”
The first DCSS Integrated Systems Safety Analysis Review was held in early 2013, providing NASA its first look at the DCSS safety and reliability analysis products. Since that time, SNC has worked closely with NASA to find opportunities for improvement, and has made significant updates to the design of the vehicle aimed at improving safety and reliability.
