The Virgin Galactic suborbital SpaceShipTwo has completed a key flight test at the Mojave Air and Space Port in California — an on-the-fly appraisal that serves as an important precursor to upcoming hot-engine flights using its hybrid rocket motor.

After a high-altitude release from the WhiteKnightTwo mothership, SpaceShipTwo  was piloted to a smooth runway touchdown Wednesday (Dec. 19), scoring a successful test drop and checking off a number of milestones.

"Today was a big step closer to first powered flight," said George Whitesides, CEO and president of Virgin Galactic, a spaceliner firm backed by British entrepreneur Richard Branson.

"We had a variety of systems newly installed on the vehicle," Whitesides told "The most important were the components of the rocket system, including all the flight-ready tanks and valves. But we also flew with flight-ready thermal protection materials on the leading edges of the vehicle for the first time," he said.

More work to do

Whitesides said that the flight team and Virgin Galactic were pleased to see that the vehicle, under the steady hand of pilot Mark Stucky, retained its excellent flight characteristics. 

"We still have a bit more work to do before we will be ready to ignite the rocket, including two more glide flights," Whitesides said. "2013 will be a big year," he said.

According to veteran Mojave Air and Space Port tarmac watcher Bill Deaver, SpaceShipTwo landed just before 8 a.m. PST under "crystal clear Mojave dawn skies," he told "It looked like they tried a new, long, high key pattern of one circuit around the field rather than the former, shorter circuit on landing."

SpaceShipTwo is a hybrid motor-powered vehicle designed to fly six passengers and two pilots to the edge of space, without making a full orbit of Earth. Commercial operations of the craft will eventually be carried out at New Mexico's Spaceport America.

The price per seat for a SpaceShipTwo space traveler is $200,000 — so there's still time to start saving your money!
