How is Spaceship One Uniquely Designed to Achieve its Goals?

  • September 9

SpaceShipOne is a rocket-powered aircraft with sub-orbital spaceflight capability at speeds of up to 3,000 ft/s (900 m/s). Its unique design features a “feathering” atmospheric reentry system where the rear half of the wing and the twin tail booms fold 70 degrees upward.
