Deep Sky

Astronomers have used the Hubble space telescope to discover the faintest and most distant galaxies ever seen. A new camera fitted to the orbiting observatory in May by shuttle astronauts has captured dim red "star cities" that formed only 600-900 million years after the Big Bang. 2009

Commercial Enterprise

On June 21, 2004, … the launch of SpaceShipOne, the first private-venture craft to attempt to leave the earth's atmosphere and enter space, defined as an altitude of 100 kilometers (62 miles).  

The one space tourism venture that has garnered the most interest in recent months, however, has been Virgin Galactic. Days before the first Ansari X Prize flight, Virgin announced it was partnering with Scaled Composites and Mojave Aerospace Ventures—the joint venture of Scaled and financier Paul Allen—to create a suborbital space tourism business flying vehicles based upon SpaceShipOne. Since then the company has released few details about its plans: the news section of Virgin Galactic’s web site was last updated on October 4, when SpaceShipOne made its final, prize-winning flight.

However, during Saturday’s sessions of the National Space Society’s International Space Development Conference in Arlington, Virginia, Virgin Galactic executives offered a host of new details about their plans for suborbital spaceflights and beyond.

The Virgin Galactic experience

Even though the first commercial flights of Virgin Galactic’s SpaceShipTwo are still nearly three years away—spring 2008 under current plans—the company has paid considerable attention to the experience its customers will have. “What we’re doing is giving you a two-hour experience of going into space that will only require a few days of training,” said Will Whitehorn, president of Virgin Galactic. - 2005

Virgin Galactic

December 8, 2009—Aspiring space tourists got a first look at their future ride late Monday, when Virgin Galactic unveiled the first of its long-awaited SpaceShipTwo planes (pictured with wings folded upward, suspended from the middle of its twin-fuselage launch vehicle). Projected fare = $200,000.00
