An ambitious billionaire has revealed his plans to colonize Mars - and charge 80,000 brave souls $500,000 to be flown there.

　　Elon Musk, the billionaire founder and CEO of the private spaceflight company Space X, has announced his vision for life on the Red Planet.He says the settlement plan would start small, with a pioneering group of fewer than 10 people, who he would take there on a reusable rocket powered by liquid oxygen and methane.Musk, already the first private space entrepreneur to launch a successful mission to the International Space Station, says what would begin by first sending fewer than 10 people could blossom "into something really big”. “At Mars, you can start a self-sustaining civilization and make it into something really big," he told the Royal Aeronautical Society in London last week.

　　Laying out precise details and figures to his "difficult" but "possible" plans, the space pioneer says the first ferry of explorers would be no more than 10 people at a price tag of $500,000(￡312,110)Per ticket.“The ticket price needs to be low enough that most people in advanced countries, in their mid-forties or something like that could put together enough money to make the trip," he said.

　　Rather than lounging around on an interplanetary vacation, the passengers would be sent to work, carrying with them equipment to build sustainable housing on the dusty and currently barren soil for future generations.Immediate ground work would focus on building transparent domes pressurized with CO2 while possibly covered in a layer of water to serve as protection from the sun.With the CO2, Mars' soil would be capable of growing crops for food, he said.Additional equipment carried over could also produce fertilizer, methane and oxygen using the atmosphere's natural elements of nitrogen, carbon dioxide and its surface of ice water.

　　Musk believes one person out of every 100,000 people would be interested in making the journey with 8 billion expected on Earth by time his plans become reality.
