Elon Musk has put his Mars-colonization vision to paper, and you can read it for free. SpaceX's billionaire founder and CEO published the plan, which he unveiled at a conference in Mexico in September 2016, in the journal New Space. From a report: The paper outlines early designs of the gigantic spacecraft, designed to carry 100 passengers, that he hopes to construct. "The thrust level is enormous," the paper states. "We are talking about a lift-off thrust of 13,000 tons, so it will be quite tectonic when it takes off." Creating a fully self-sustained civilisation of around one million people -- the ultimate goal -- would take 40-100 years according to the plans. Before full colonisation takes place, though, Musk needs to entice the first pioneers to pave the way.
