Ashton Kutcher is space bound.

Following in the footsteps of elite celebrity space travelers like Lance Bass, the famed perma-bro actor and Twitter pioneer has signed up to break the exosphere as the 500th passenger on Richard Branson's Virgin Galactic airline (spaceline?).

Virgin Galactic hasn't actually begun operations yet (the company has refused to offer a timeline for its first commercial flights), but Branson is hopeful to start sending millionaires and annoying sons-in-law into the black abyss soon.

Other celebrities that have signed up to be among Virgin Galactic's first passengers include Tom Hanks, Katy Perry, Brad Pitt and Angelina Jolie. The cost of commercial space flight? $200,000.
