It's curious how little is written about the X-37B that seems to be a successful reusable space vehicle. It's unmanned, very much smaller than the Shuttle but seems to be of use for the US Air Force for something. It also stays in orbit for over a year at a time. http://en.wikipedia.org/wiki/Boeing_X-37 http://en.wikipedia.org/wiki/Boeing_X-37
