Sierra Nevada Corp. (SNC) Space Systems recently hosted discussions with NASA about the non-toxic propulsion systems that would power the Dream Chaser spacecraft’s main and reaction control systems.

The reaction control system will give the spacecraft the ability to steer in space by providing small amounts of directional thrust for docking with the International Space Station. The main propulsion system is much more powerful, and generally capable of providing thrust in one direction for aborts or orbital insertion burns.

SNC is working toward a milestone to test the propulsion systems during its Commercial Crew Integrated Capability (CCiCap) partnership with NASA’s Commercial Crew Program (CCP).
