More than 500 people—including American actor Ashton Kutcher—will become “astronauts” next year.

They have each paid $200,000 for a two-hour flight on SpaceShipTwo.

The aircraft will take them very high and very fast—in fact, they will break the sound barrier.

A British company called Virgin Galactic, which is owned by a well-known and famously daring billionaire named Sir Richard Branson, tested its new aircraft last week.

During the test, the spacecraft flew 69,000 feet high over the Mojave Desert, in the U.S.

SpaceShipTwo will take passengers, six at a time, into the atmosphere at 2,500 miles per hour—more than three times the speed of sound.

Passengers will experience a lack of gravity. During the flight they’ll be able to leave their seat and do a mid-air summersault, according to Virgin’s website.

“SpaceShipTwo’s cabin will have lots of room for zero g fun,” the website says.
