The Scaled Composites Model 339 SpaceShipTwo (SS2) is an air-launched suborbital spaceplane type designed for space tourism. It is manufactured by The Spaceship Company, a California-based company owned by Virgin Galactic.
SpaceShipTwo is carried to its launch altitude by a Scaled Composites White Knight Two, before being released to fly on into the upper atmosphere powered by its rocket engine. It then glides back to Earth and performs a conventional runway landing. The spaceship was officially unveiled to the public on 7 December 2009 at the Mojave Air and Space Port in California. On 29 April 2013, after nearly three years of unpowered testing, the first one constructed successfully performed its first powered test flight.
Virgin Galactic plans to operate a fleet of five SpaceShipTwo spaceplanes in a private passenger-carrying service and has been taking bookings for some time, with a suborbital flight carrying an updated ticket price of US$250,000. The spaceplane could also be used to carry scientific payloads for NASA and other organizations.
On 31 October 2014 during a test flight, VSS Enterprise, the first SpaceShipTwo craft, broke up in flight and crashed in the Mojave desert. A preliminary investigation suggested the feathering system, the craft's descent device, deployed too early. One pilot was killed; the other was treated for a serious shoulder injury after parachuting from the stricken spacecraft.
The second SpaceShipTwo spacecraft, VSS Unity, was unveiled on 19 February 2016. and the vehicle is currently undergoing flight testing.
The SpaceShipTwo project is based in part on technology developed for the first-generation SpaceShipOne, which was part of the Scaled Composites Tier One program, funded by Paul Allen. The Spaceship Company licenses this technology from Mojave Aerospace Ventures, a joint venture of Paul Allen and Burt Rutan, the designer of the predecessor technology.
