Hollywood actor Ashton Kutcher is the 500th customer to sign up for Virgin Galactics trip into outer space. Virgin CEO Sir Richard Branson made the announcement on his blog. He said, ''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 themagic of space for himself.'' Branson added, ''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.'' The date of Kutchers space flight is yet to be announced, reported Contactmusic. According to the firms official website, tickets for the trip cost $200,000.
