SpaceShip2 (VSS Enterprise) glides toward Earth on its first test flight after release from the mothership, 'WhiteKnight2' (VMS Eve) over the Mojave Desert in California, on October 10, 2010. The craft was piloted by engineer and test pilot Pete Siebold from Scaled Composites. A seat on Virgin Galactic spaceship will cost $200,000 per person, with refundable deposits starting at $20,000. Virgin Galactic has managed to sell 700 seats thus far. Virgin Galactic space flights are the brainchild of British Sir Richard Branson, who heads up the Virgin empire.
