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 4 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 worlds 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.
