No one from Earth has visited Mars yet, and Elon Musk wishes to change that in a quite big way. The SpaceX CEO says we need to put a million people on the Red Planet to make certain that human civilization survives. Elon Musk said in an interview with the digital magazine Aeon "I think there is a strong humanitarian argument for making life multi-planetary... in order to safeguard the existence of humanity in the event that something catastrophic were to happen," Musk's statement sounds ominous but may not be off the mark, given the dangers that researchers see in climate change and space rocks.

Just what would it take to transfer so many people from Earth to Mars?
Musk told Aeon "Excluding organic growth, if you could take 100 people at a time, you would need 10,000 trips to get to a million people. But you would also need a lot of cargo to support those people. In fact, your cargo to person ratio is going to be quite high. It would probably be 10 cargo trips for every human trip, so more like 100,000 trips. And we’re talking 100,000 trips of a giant spaceship." This isn't the first time Musk has made a pitch for colonizing Mars. At the AllThingsD's 2013 conference last year, Musk said, "Either we spread Earth to other planets, or we risk going extinct... An extinction event is inevitable and we’re increasingly doing ourselves in." Got it. You can read the full interview in Aeon magazine.
