> So far nobody Well...Elon has made guesses/estimates/given us lots of ideas about his monetization strategy. I think the most promising is to sell tickets at $500,000 apiece, which he thinks will be about the going market price to meet a demand of ~100,000 colonists. Mars One thinks they can do it on a TV show (they'll fail, though, obviously). My point is that your "nobody" comment is unfair and incorrect. Lots of intelligent, capable and experienced people have articulated a number of different business models around the colonization of Mars. None of them are proven, of course, but that will take time.
