About Richard Branson:
He’s ballooned across the Atlantic, floated down the Thames with the Sex Pistols, and been knighted by the Queen. His megabrand, Virgin, is home to more than 250 companies, from gyms, gambling houses and bridal boutiques to fleets of planes, trains and limousines. The man even owns his own island.

And now Richard Branson is moving onward and upward into space (tourism): Virgin Galactic’s Philippe Starck-designed, Burt Rutan-engineered spacecraft are slated to start carrying passengers into the thermosphere in 2009, at $200,000 a ticket.

Branson also has a philanthropic streak. He’s pledged the next 10 years of profits from his transportation empire (an amount expected to reach $3 billion) to the development of renewable alternatives to carbon fuels. And then there’s his Virgin Earth Challenge, which offers a $25 million prize to the first person to come up with an economically viable solution to the greenhouse gas problem.
