Mojave, Calif. ? The sleek, bullet-shaped spacecraft is about the size of a large business jet — with wide windows and seats for six well-heeled passengers to take a thrill ride into space.

It’s billed as the world’s first commercial spaceship, designed to be carried aloft by an exotic jet before firing its rocket engine to climb beyond the Earth’s atmosphere.

In a Hollywood-style rollout, Virgin Galactic on Monday took the cloak off SpaceShipTwo, which had been under secret development for two years in the Mojave Desert. The company plans to sell suborbital space rides for $200,000 a ticket, offering passengers 2 1/2-hour flights that include about five minutes of weightlessness.

“Isn’t this the sexiest spaceship ever?” said British billionaire and Virgin Galactic founder Sir Richard Branson, who partnered with famed aviation designer Burt Rutan on the venture.

The stubby-winged spaceship possesses a slender fuselage that narrows at the nose and tail. Once in space, its unique twin tail booms can pivot upward to increase drag and allow the spaceship to plunge like a shuttlecock back into the atmosphere.
