Orion, which looks like a far-out hypersonic jet, is similar in idea to NASA's Dyna Soar project. You can get a good idea of its capability by imagining it to be a much bigger X-15. The X-15, a supersonic, high-altitude experimental plane, could be modified to boost itself beyond the earth's atmosphere, the way Orion does.
