Space, the final frontier. Or, you know, that place where Ashton Kutcher will soon be hanging out. The Two and a Half Men thespian is Virgin Galactic’s 500th customer for a roundtrip ticket to outer space. Worth about $140 million, Kutcher can easily afford the $200,000 price tag for the SpaceShipTwo rocket plane trip to 62 miles out, where passengers can see the arc of Earth and the black sky above. Other celebs rumored to be on the “list” of people planning a Virgin space voyage: Katy Perry, Brad Pitt and Angelina Jolie, and Beyonce and Jay-Z—it’s not clear whether Blue Ivy Carter will join in. Commercial service isn’t expected to begin until at least 2013.
