The spaceplane being developed by UK billionaire Sir Richard Branson has made its first powered flight.
The vehicle was dropped from a carrier aircraft high above California's Mojave Desert and ignited its rocket engine to go supersonic for a few seconds.
Sir Richard's intention is to use the spaceship to carry fare-paying passengers on short pleasure rides above the Earth's atmosphere.
His company Virgin Galactic has already taken hundreds of deposits.
The rocket vehicle is known as SpaceShipTwo (SS2).
Although it has been in the air on more than 20 occasions, this was the first time its hybrid motor had been ignited.
It was only a short burn lasting about 16 seconds, but it propelled SS2 beyond the sound barrier to a speed of Mach 1.2. Future outings should see progressively longer burn durations, enabling the plane eventually to reach sufficient velocity to climb more than 100km into the sky.
