Default Elon Musk's plan to go to Mars (Article)

The big unanswered question, for me, is how to get the rocket up off Mars again? Leaving the Moon to return to Earth was doable in 1969 because of the low Lunar gravity. While Mars' gravity is not as high as Earth's, it is a lot bigger than the gravitational pull of the Moon is.
