SPARKS, Nev. ( & KRNV) -- Sierra Nevada Corporation (SNC) has successfully passed Milestone 9 of the advancement testing -- The 'Risk Reduction and Technology Readiness Level.'

Milestone 9 culminated in a major comprehensive review of various hardware systems. To date, SNC has received 92 percent of the total award value of the CCiCap agreement.

SNC completed a series of Risk Reduction and TRL advancements on five major systems of the Dream Chaser. The five specific systems subjected to extensive testing were: Crew Systems, Environmental Control and Life Support Systems (ECLSS), Structures, Thermal Control (TCS) and Thermal Protection Systems (TPS).

With the successful completion of Milestones 9 and 9a, SNC has continued to demonstrate that it puts safety first.

“By thoroughly assessing and mitigating each of the previously identified design risks, SNC is continuing to prove that Dream Chaser is a safe, robust, and reliable spacecraft,” said Mark N. Sirangelo, corporate vice president of SNC’s Space Systems. “These crucial validations are vital steps in our Critical Design Review and in showing that we have a very advanced and capable spacecraft. This will allow us to quickly and confidently move forward in restoring cutting-edge transportation to low-Earth orbit from the U.S.”

The comprehensive set of tests were in addition to the Risk Reduction and TRL advancement tests completed on the Main Propulsion System and Reaction Control System. The data collected from the more than 3,500 tests completed over a year during these two milestones resulted in continued maturation of the Dream Chaser spacecraft design.
