![]() In contrast, orbital spacecraft re-enter at orbital speeds, close to 25,000 km/h (16,000 mph), using heat shields. SpaceShipTwo uses a feathered reentry system, feasible due to the low speed of reentry. ![]() The wing span is 8.2 m (27 ft), the length is 18 m (59 ft) and the tail height is 4.6 m (15 ft). SpaceShipTwo's crew cabin is 3.7 m (12 ft) long and 2.3 m (7 ft 7 in) in diameter. After 70 seconds, the rocket engine cuts out and the spacecraft will coast to its peak altitude. It launches from its mother ship, White Knight Two, at an altitude of 15,000 m (49,000 ft), and reaches supersonic speed within 8 seconds. SpaceShipTwo was designed to reach 4,200 km/h (2,600 mph), using a single hybrid rocket engine - the RocketMotorTwo. The predecessor craft, SpaceShipOne's target was also 100 km but the last flight reached an altitude of 112 km (70 mi). The apogee of the new craft was designed to be approximately 110 km (68 mi) in the lower thermosphere, 10 km (6.2 mi) higher than the Kármán line but as of July 2021, the maximum height reached was 89.9 km. Its capacity will be eight people - six passengers and two pilots. ![]() SpaceShipTwo is a low-aspect-ratio passenger spaceplane. 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. 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. Its first flight to space (above 50 miles altitude), VSS Unity VP03, took place on 13 December 2018. The vehicle is undergoing flight testing. The second SpaceShipTwo spacecraft, VSS Unity, was unveiled on 19 February 2016. One pilot, Michael Alsbury, was killed the other was treated for a serious shoulder injury after parachuting from the stricken spacecraft. A preliminary investigation suggested that the craft's descent device deployed too early. On 31 October 2014, during a test flight, the first SpaceShipTwo VSS Enterprise broke up in flight and crashed in the Mojave desert. The spaceplane could also be used to carry scientific payloads for NASA and other organizations. 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. On 29 April 2013, after nearly three years of unpowered testing, the first one constructed successfully performed its first powered test flight. ![]() The spaceship was officially unveiled to the public on 7 December 2009 at the Mojave Air and Space Port in California. It then glides back to Earth and performs a conventional runway landing. 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 is manufactured by The Spaceship Company, a California-based company owned by Virgin Galactic.
