Virgin Galactic showed off for the public its SpaceShipTwo, a craft that will take passenger astronauts into sub-orbital flights as early as next year.

The unveiling at the Mojave Air and Spaceport was another milestone in Virgin Galactic’s role in the private commercial space industry.

SpaceShipTwo, dubbed Enterprise, was designed by Scaled Composites based at the Mojave spaceport. The craft can carry up to six passenger astronauts and two pilot astronauts.

Enterprise will be carried by WhiteKnightTwo to an altitude of 50,000 feet and dropped before the spaceplane fires its rocket engines for its sub-orbital flight.
