Dream Chaser Manned Systems Briefing Dream Chaser is a proposed American manned reusable spaceplane. The winged vehicle is designed for vertical take-off and horizontal landing (on con- ventional runways). Its main mission would be to provide NASA a commercial service for transporting crew and cargo to and from the International Space Station (ISS) in low earth orbit (LEO), although at the moment an unmanned autonomous ver- sion of the vehicle has been con- engine.
