Via Richard Branson's blog:
Great news today news from our Astronaut Relations team at Virgin Galactic: our 500th future astronaut customer has just signed up! Even better news is that number 500 is Ashton Kutcher. I gave Ashton a quick call to congratulate and welcome him. 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 the most exciting business that we’ve ever launched and I still sometimes have to pinch myself that it’s for real. Ashton is joining a fast expanding group of true pioneers who are on their way to a life changing experience and a place in the history books. It’s great to have him on board.
So, um, that's happening.
