Virgin Galactic's unveiling of the SpaceShipTwo rocket plane drew hundreds of paying space tourists and travel agents, rocket geeks and glitterati to the Mojave Air and Space Port. For a while, it looked as if stormy skies and brisk winds would force a change in Virgin billionaire founder Richard Branson's plans for an after-dark, outdoor debut.
But in the end, the spotlights went on and the music blared as scheduled, despite the near-freezing temperatures, the wind and the puddles of rain. SpaceShipTwo rolled down the runway, suspended from its WhiteKnightTwo carrier airplane. California Gov. Arnold Schwarzenegger and New Mexico Gov. Bill Richardson stepped out and smashed bottles of champagne - and Branson's daughter, Holly, officially gave the 60-foot-long craft its new name: the VSS Enterprise.
The name pays tribute to the sailing ships of old as well, to the fictional "Star Trek" starship - and to the idea that the craft will bring private enterprise into the world of space travel, said Virgin Galactic's president, Will Whitehorn.
SpaceShipTwo has been under development for years in a Mojave hangar at Scaled Composites - the company that built the craft's predecessor, SpaceShipOne, to win a $10 million prize for private spaceflight five years ago.
Branson is spending an estimated $250 million to $400 million on his space venture, which will involve building at least six SpaceShipTwo planes and two WhiteKnightTwo motherships. The company already has signed up more than 300 would-be spacefliers, including actress Victoria Principal, Hollywood director Bryan Singer and 90-year-old enviro-theorist James Lovelock. Paralyzed cosmologist Stephen Hawking, who sampled zero-G two years ago, may eventually fly as well.
What SpaceShipTwo will do
SpaceShipTwo is designed to carry six passengers and two pilots to the edge of outer space, past the 100-kilometer (62-mile) altitude mark. The flight profile would provide about five minutes of weightlessness, a commanding view of a curving Earth below the black sky of space, and the world's highest roller-coaster ride going up and coming down.
Rutan has kept mum about his expectations for the flight schedule, but observers guess that 2011 or 2012 is the likeliest time frame for the start of commercial service. Between now and then, SpaceShipTwo is likely to go through scores of tests. Ground testing starts on Tuesday, Branson told.
The first flight tests, due to begin next year, would involve captive-carry flights during which the rocket plane would ride between WhiteKnightTwo's twin cabins so that Scaled's team can check the aerodynamics of the combined crafts. Then there would be drop tests, in which SpaceShipTwo would be released and piloted through a glide back down to Earth.
Eventually, the hybrid rocket motor would be added to the mix: SpaceShipTwo would light up its engine in a series of powered flights, climaxing with the full profile for commercial service. SpaceShipTwo would be dropped from WhiteKnightTwo at a height of 60,000 feet, blast off, rise to spaceworthy heights and go supersonic on the way down.
The making of SpaceShipTwo
SpaceShipTwo's passenger cabin is being placed on the fuselage inside Scaled Composites' hangar in Mojave, Calif.
The full-scale rocket motor to be used in SpaceShipTwo is successfully test-fired on May 6, 2009, at the Northrop Grumman test facility in San Clemente, Calif. The hybrid rocket motor was built by Scaled Composites and SpaceDev.
Windows dot the interior of the SpaceShipTwo passenger cabin, as seen during an early stage of the rocket plane's construction. The design is aimed at making sure each of the six passengers has a view of the curving Earth and the black sky of space from a height of 62 miles (100 kilometers).
Virgin Galactic's billionaire founder, Richard Branson, flashes a grin as he stands in front on VMS Eve, the WhiteKnightTwo airplane that will eventually carry SpaceShipTwo to its air launch. Branson took his first flight on Eve in July 2009 at the EAA AirVenture air show in Oshkosh, Wis. The plane is named after Branson's mother, who inspired the painting on the fuselage.
Virgin Group employees sit in the cabin of a prototype Virgin Galactic SpaceShipTwo spacecraft at London's Science Museum in February 2007. SpaceShipTwo is designed to carry six passengers and two pilots to the edge of outer space for a few minutes of weightlessness and an out-of-this-world view. The fare is $200,000 per passenger.
Sunlight glints off Eve, Virgin Galactic's first WhiteKnightTwo mothership, on the eve of its rollout on July 28, 2008, in Mojave, Calif. The airplane has twin cabins, and the SpaceShipTwo rocket plane is designed to be attached to the wing structure between the cabins.
The WhiteKnightTwo carrier plane known as Eve flies over mountains during a test flight from its home base at California's Mojave Air and Space Port. Eve is to serve as the mothership for Virgin Galactic's SpaceShipTwo rocket plane. SpaceShipTwo's test flights are due to begin in 2010.
