At an aircraft hangar deep in the Mojave Desert this morning, the space tourism company Virgin Galactic unveiled one of the crafts that will boost paying customers up to the edge of space. Called the “WhiteKnight Two” by British tycoon Richard Branson, the vehicle will act as a mothership by flying to 48,000 feet with a smaller spacecraft slung between its twin fuselages. Then the spacecraft, SpaceShip Two, will detach and fire its rocket engines to take the six passengers the rest of the way up.
A crowd of engineers, dignitaries and space enthusiasts gathered inside a Mojave Desert hangar for the unveiling countdown. As the hangar door flew open, White Knight Two appeared outside under the sunny desert sky with Branson and American aerospace pioneer Burt Rutan waving from the cabin. White Knight Two, billed as the world’s largest all-carbon-composite aircraft, is “one of the most beautiful and extraordinary aviation vehicles ever developed,” Branson said [AP].

When the private space company SpaceX launches its Falcon 1 rocket at the end of July, it will bring an intriguing experiment into orbit: a small NASA satellite that could be maneuvered through space with an attached “solar sail.” The sail would be powered by photons from the sun hitting the reflective surface, a series of tiny impacts that can provide a boost in the frictionless void of space.
In a video, NASA scientists show off a satellite about the size and shape of a shoebox with four masts that spring out to support the sail, which measures 100 square feet when unfurled. If the sail is successfully deployed, NASA will experiment with using the sail to control the satellite’s altitude and orbital maneuvering.
To understand this technology’s potential, consider that it took the Voyager probes 30 years to get to the edge of the solar system where they are still hurtling outward further every day. Although slower to get started, a solar sail could catch up with a Voyager spacecraft in a single decade [Wired News].

Against the classic backdrop of New York City’s Explorers Club, a brash entrepreneurial space company held a press conference today to announce its latest customers, who have pledged to pay exorbitant prices to take pleasure cruises to space. In a sign that the space tourism market is taking off, the company’s executives also declared that business is so strong that they’re leasing more seats from their partner, the Russian space agency.
The company, Space Adventures, is playing up the scientific and educational possibilities of each mission, seemingly trying to dispel the notion that astronomically wealthy folks are spending bushels of money just to take pretty pictures of Earth from the International Space Station.
