SpaceDev Proposing Orbital Launch System

SpaceDev, the makers of the hybrid rocket engine which propelled SpaceShipOne to last year's completion of the X-Prize challenge, are nearing completion of an initial study for NASA that lays out plans for a 6 person reusable spacecraft capable of reaching low Earth orbit.

The plan calls for a number of sub-orbital flights by 2008 and a orbital flight by 2010.
