Virgin Galactic, an US company developing a commercial manned space flight system and tourism business, has completed the first piloted free flight of SpaceShipTwo, named the VSS Enterprise.
The spaceship was released from its mothership at an altitude of 45,000ft (13,700 metres).
During its first flight the spaceship was piloted by Pete Siebold, assisted by Mike Alsbury as co-pilot. The two main goals of the flight were to carry out a clean release of the spaceship from its mothership and for the pilots to free fly and glide back and land at Mojave Air and Space Port in California.
Other detailed objectives of the flight were successfully completed, including; verification that all systems worked prior and following the clean release of Enterprise; initial evaluation of handling and stall characteristics; qualitative evaluation of stability and control of SS2 against predictions from design and simulation work; verification of performance by evaluating the lift-to-drag ratio of the spaceship during glide flight; practice a landing approach at altitude and finally descend and land.
Preparations for the milestone flight were extensive. The WhiteKnightTwo mothership (Eve) flew 40 times including four captive carry flights of spaceship and mothership mated together. The most recent captive carry was on 30 September 2010. The most recent solo flight was on 5 October 2010 and demonstrated that all the systems required for a free flight by the VSS Enterprise were functioning correctly without any safety issues.
Commenting on the successful flight Scaled Composites pilot, Pete Siebold, said, “The VSS Enterprise was a real joy to fly, especially when one considers the fact that the vehicle has been designed not only to be a Mach 3.5 spaceship capable of going into space but also one of the world’s highest altitude gliders.”
Sir Richard Branson, founder of Virgin Group, who was present during the first successful flight, added “This was one of the most exciting days in the whole history of Virgin. For the first time since we seriously began the project in 2004, I watched the world’s first manned commercial spaceship landing on the runway at Mojave Air and Space Port and it was a great moment. Now, the sky is no longer the limit and we will begin the process of pushing beyond to the final frontier of space itself over the next year.”
Virgin Galactic’s future commercial operations will be at Spaceport America in New Mexico where final preparations are taking place for a finished runway inauguration ceremony on Friday, 22 October 2010.
The National Geographic channel in the United States will be showing a documentary on the build up and preparation for the first flight of VSS Enterprise on Monday, 18 October at 22:00 ET/PT.
