LAS CRUCES, N.M. – A thruster glows red during a hot-fire test for Boeing’s CST-100 spacecraft orbital maneuvering and attitude control OMAC system. During the tests at NASA’s White Sands Test Facility in Las Cruces, N.M., Boeing and partner Aerojet Rocketdyne tested two thrusters to demonstrate stable combustion and performance in a vacuum, simulating a space environment. Two additional thrusters were tested in a vacuum to demonstrate long-duration mission survivability. The 24 thrusters that compose the CST-100’s OMAC system will be jettisoned with the service module after the deorbit burn, prior to re-entry. The tests completed Milestone 9 of the company's funded Space Act Agreement with NASA’s Commercial Crew Program, or CCP, during the Commercial Crew Integrated Capability, or CCiCap, initiative. CCP is intended to lead to the availability of commercial human spaceflight services for government and commercial customers to low-Earth orbit. Future development and certification initiatives eventually will lead to the availability of human spaceflight services for NASA to send its astronauts to the International Space Station, where critical research is taking place daily.
