The Scaled Composites SpaceShipThree (SS3) is a proposed spaceplane to be developed by Virgin Galactic and Scaled Composites if SpaceShipTwo is successful. The originally proposed vehicle mission was orbital spaceflight. As of 2008, the company has scaled back those plans and articulated a design that would be a point-to-point vehicle traveling outside the atmosphere.
