Musk on how quickly he wants to see humans on Mars:
This is a very difficult thing, obviously. I’m hopeful that the first people could be taken to Mars in 10, 12 years. I think it’s certainly possible for that to occur. The thing that matters long term is to have a self-sustaining city on Mars. To make life multi-planetary. That will define a fundamental bifurcation of the future of human civilization. We’ll either be a multi-planet species and out there among the stars, or a single-planet species until some eventual extinction event, natural or man-made.
