Photos: That's one small step for SpaceShipTwo

Virgin Group founder Sir Richard Branson (left) and Scaled Composites CEO Burt Rutan show off the final design for Virgin Galactic's SpaceShipTwo at an event on Wednesday morning at New York's American Museum of Natural History.

Members of the press, as well as special guests and about 100 of the 200 deep-pocketed travelers who have reserved $200,000 seats aboard the craft, which aims to be the first commercial suborbital spacecraft for the private sector, were present for the unveiling of the design.

Construction of the actual SpaceShipTwo is nearly 60 percent complete. Virgin Galactic hopes that it will make its first flight in 2009. Final images and mockups have changed quite a bit from older designs, like these from 2006.
