RocketAcademy writes "British billionaire Richard Branson, whose Virgin Galactic company is backing the development of SpaceShip Two, has told CBS News he is 'determined to start a population on Mars.' He said, 'I think over the next 20 years, we will take literally hundreds of thousands of people to space and that will give us the financial resources to do even bigger things. That will give us the resources then to put satellites into space at a fraction of the price, which can be incredibly useful for thousands of different reasons.' Branson isn't the only billionaire interested in the Red Planet. Elon Musk, founder of Space Exploration Technologies (SpaceX), wants to put humans on Mars in the next 12 to 15 years."
