During the flight, the reaction control system was tested, that the plane once in a ballistic trajectory of position may change. In addition, the thermal coating was tested, as well as the rocket motor, that burned twenty seconds. On the ground, the rocket engine tested for extended periods.

Virgin Galactic wants to offer its first commercial space flights this year. Before the SpaceShipTwo will probably still have to rise to greater heights: an altitude of 100 kilometers, is generally used as the boundary between Earth and space. The predecessor of the SpaceShipTwo, the height of one hundred kilometers already met.

According to meteorologists, the space otherwise only starts at 10,000 kilometers, even where the atmosphere ends. Some physicists space starts at 20 million miles away and from here the gravity of the earth no longer prevail.
