Dream Chaser Completes Free Flight Test

"Completion of Dream Chaser's free flight test on Nov. 11, 2017, was a major milestone under a space act agreement with NASA's Commercial Crew Program. NASA selected Sierra Nevada Corp., along with Orbital ATK and SpaceX, for the agency's second commercial resupply contracts to deliver critical science, research and technology demonstrations to the International Space Station from 2019 to 2024."
