Like the shuttle, Dream Chaser's primary mission is to carry crew and cargo into low-Earth orbit and the International Space Station. Its developer, the Sierra Nevada Corporation, says the re-usable craft will be able to land on conventional runways.
Pictured above left is a scale model of Nasa's HL-20, the Dream Chaser's inspiration. On the right, a wire-frame image, again of the HL-20. Before the Dream Chaser launches in 2015, it needs to pass a safety checklist that includes, atmospheric, orbital and crew-rated testing.
