Orbital Space Plane Program
Based largely on existing technologies, the Orbital Space Plane would provide safe, affordable access to the International Space Station. The Orbital Space Plane program is more than a spacecraft. The program will take an integrated systems approach to design the entire space transportation system — including ground operations, space vehicle and all supporting technologies needed to conduct a mission to and from the International Space Station. In addition, flight demonstrators such as the X-37 vehicle will flight test advancing technologies to reduce the risk of future reusable launch vehicle systems including the Orbital Space Plane.
The program will place emphasis in reusable kerosene engine designs and — in concert with Department of Defense initiatives — on a variety of launch system technologies, including development of air-breathing hypersonic propulsion systems.
