The head of SpaceX, a space exploration company, is laying out a plan for humans to colonize Mars, the planet. And Elon Musk says this could happen in 50 to 150 years, though he wants to get it started, sending the first humans to Mars in the year 2024.
ELON MUSK, CEO TESLA MOTORS: I think there are two main motivations for Mars. I mean, one is, is the sort of defense reason of saying, OK, if something would have happened to Earth, is live as we know it, does it end? Or if it`s on another planet, then it probably doesn`t end.
Multi-planet civilization is likely to last a lot longer than a single civilization.
The other part of it is, just being an incredible adventure. It would be a very exciting and even if somebody never plan to go to Mars, just following the progress I think would -- vicariously would be quite aspiring.
AZUZ: But at the moment, quite expensive. Musk says it costs $10 billion to get someone there with today`s technology. He wants to get the price of a ticket down to $200,000 per person, through the development of newer and more advanced systems. He says, ultimately, the mission would need a combo of private and government funds.
The downsides: Musk says that people wanting to go to Mars would have to be prepared to die, that the fatally risk would be high. Also, SpaceX is currently dealing with setbacks, like the explosion of one of its rockets on a launch pad earlier this month. But the company, like the U.S. government, is working to send people far beyond the moon.
