Richard Branson's Virgin Group is on track to become the world's first commercial spaceline, with suborbital flights for space tourists due to start in 2008, the British billionaire said on March 29.
In an interview with Reuters in Dubai, where his Virgin Atlantic airline began flights from London this week, Branson said other companies offering space travel had not matched the progress made by the Virgin Galactic venture.
"A number of companies around the world are offering space travel but they haven't tested and built any space ships. They certainly haven't had test flights into space," Branson said.
"Virgin is the only company in the world that has actually achieved that," he added.
Virgin Galactic will offer space flights for $200,000, and says it has already received more than 150 firm reservations and taken $13.1 million in deposits. Some 45,000 people have expressed an interest in the trips.
The spacecraft to be used by Virgin is based on SpaceShipOne, which in 2004 won the $10 million Ansari X prize offered to the first private organisation to launch a reusable manned spacecraft into space twice within two weeks. Virgin is building five models of SpaceShipTwo, a larger version.
The craft is attached to a larger plane - White Knight Two - for take-off from the ground, and then detaches at 50,000 feet from the carrier aircraft before accelerating rapidly and entering sub-orbital space. Virgin says customers will spend 15 minutes in space, including five minutes of weightlessness.
"You'll go up under the mother ship, attached to it; you'll be dropped away and then you'll have the rush of your life as the craft goes from zero miles an hour to 4,000 miles an hour, taking you into space where you will be able to unfasten your seatbelt and enjoy weightlessness, see the curve of the earth and see the atmosphere," Branson said.
The entrepreneur says he plans to be on the first commercial Virgin Atlantic flight along with his children and parents - including his 91-year-old father. Branson says safety is of paramount importance to the venture.
