You can be like Ashton Kutcher, Angelina Jolie and other celebrities who have signed up to board the Virgin Galactic's SpaceShipTwo and be one of the first space tourists in history.

Ashton Kutcher became the 500th person to sign with Virgin Galactic, which is currently running test flights and has no timetable for the first launch.

I gave Ashton a quick call to congratulate and welcome him, said Virgin Group Chairman Sir Richard Branson in a statement on virgingalactic.com. He is as thrilled as we are at the prospect of being among the first to cross the final frontier (and back!) with us and to experience the magic of space for himself.

Virgin Galactic is a space flight project spearheaded by Sir Richard Branson, chairman of the Virgin Group whose hobbies include ballooning adventures and record-breaking feats.

Aside from Ashton Kutcher, other celebrities who made a deposit to be one of the first space tourists include Angelina Jolie, Brad Pitt, Katy Perry and Tom Hanks, according to USA Today.

SpaceShipTwo, the ship that will propel Virgin Galactic customers into space, has room for six passengers for each flight, which Virgin Galactic says is expected to last about two hours.

All passengers will be able to leave their seats and float in zero G [gravity] should they wish and enjoy view of space and the earth stretching for around 1,000 miles in every direction, the fact sheet says.

Space tourism is not just for the famous, but you do have to be rich to join the likes of Kutcher, Jolie, Pitt, Perry and Hanks in space.

A ticket for space travel with Virgin Galactic will set you back $200,000. At least a $20,000 deposit is required to hold your spot as a Virgin Galactic astronaut.

Before boarding, Virgin Galactic requires customers to undergo three days of preparation, medical checks and acclimation to zero-gravity. You'll also be able to bond with your fellow space travelers.
