Some people theorize that life on Earth may have come from space; meaning that we humans are ‘aliens’ on Earth. And now you have people like Elon Musk talking about establishing self sustaining colonies on Mars. This whole concept seems insane, but could it actually happen some time soon?

How likely are we to actually go to Mars in our lifetime? Some people have already claimed to haveĀ been to Mars. Are we going to re-think the way we look at such people and their stories once Elon Musk takes us to Mars?

Is it possible that world governments have already completed successful missions to Mars? Is it possible that with programs like Elon Musk’s SpaceX, we may learn new details pertaining to human space travel that may or may not have been kept out of mainstream media?

Apparently, Leonardo DiCaprio has signed up to be among the first SpaceX passengers on Elon Musk’s mission to Mars.
