Elon Musk: We Must Put a Million People On Mars To Safeguard Humanity

An anonymous reader writes: Elon Musk's ambitions for SpaceX keep getting bigger. First he wanted to make the trip to Mars affordable, then he wanted to establish a city-sized colony, and now he's got his eye on the future of humanity. Musk says we need a million people on Mars to form a "sustainable, genetically diverse civilization" that can survive as humanity's insurance policy. He continued, "Even at a million, you're really assuming an incredible amount of productivity per person, because you would need to recreate the entire industrial base on Mars. You would need to mine and refine all of these different materials, in a much more difficult environment than Earth. There would be no trees growing. There would be no oxygen or nitrogen that are just there. No oil." How fast could we do it? Within a century, once the spacecraft reusability problem is solved. "Excluding organic growth, if you could take 100 people at a time, you would need 10,000 trips to get to a million people. But you would also need a lot of cargo to support those people. In fact, your cargo to person ratio is going to be quite high. It would probably be 10 cargo trips for every human trip, so more like 100,000 trips. And we're talking 100,000 trips of a giant spaceship."

    I think Musk just jumped the shark.

    That's what people said about Tesla and just about every real thinker of the past. It doesn't mean he isn't at least a little crazy. Crazy can be good. Take John Nash for example.

    There is no way to "safeguard humanity" (at least in a physical sense). It's called "entropy".

    We can hedge our bets, though.

    In Musk's case, though, I don't think he's crazy. I just think he's a charismatic con man looking to line his own pockets by selling a pipe dream.

    Really? The man was independently wealthy. He could have bought his own island and lived in luxury the rest of his life. Instead he plowed his entire fortune into Tesla and SpaceX and was a couple of weeks away from losing everything. If the 4th SpaceX launch had failed like the previous 3 or if they hadn't figured out the drivetrain problems on the Tesla roadster he would have nothing now.

    I'd think it's pretty clear that Musk is motivated by other things than money. You may agree or disagree with his dream, but there's no question the man is sincere.

    Lot of good that'll do us when Earth gets hit with a large asteroid, as it does periodically. That's why he says this is about hedging our bets, not about human happiness.

    Pedantry is often mistaken as philosophy.

    Actually history is not all that simple. Henry Ford also started paying his employees a living wage long before it was popular. In fact other industrialists hated him for raising wages.
    Ford hated unions but actually paid his workers very well for the day. It was in 1935 that the problems with the Unions happened and Ford was getting up in years. It is a lot more complicated than you think http://en.wikipedia.org/wiki/H...

    Of course Auto Workers Union revises their own history and has removed a lot of the influence of radical communists from the official history.

    He also "interfered" with his workers lives and offered programs to help with "heavy drinking", gambling, and dead-beat dads. He got a lot of flack for these programs in the day as being too intrusive.

    Henry Ford in the end was a great man but also a product of his day. Today he would be seen as racist and anti-semitic. In the early 1900s he was seen are a radical progressive. No man is all good or all bad.

    No, in case *SOMETHING ELSE* managed to fuck* up our home planet and wipe out humanity. Does the term "extinction-level event" mean anything to you? Seen any (non-feathered) dinosaurs lately?

    * we're adults here, or at least this is the Internet and you can pretend. Swearing is OK
