SpaceDev licensed the HL-20 technology from NASA and extended it to use for its new Dream Chaser suborbital spacecraft. Later, the Dream Chaser became a candidate for NASA's Commercial Orbital Transportation Services (COTS) Program for delivering cargo to and from the International Space Station. In the event, SpaceDev was not selected for award under COTS, but did sign a non-reimburseable Space Act Agreement to facilitate additional exchange of non-cash project milestones with NASA.
