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."

  8. The general issue is decentralization & resile by Paul+Fernhout · · Score: 4, Interesting

    As I discussed here (~25years ago): http://www.pdfernhout.net/prin...
    "As outlined in my statement of purpose, my lifetime goal is to design and construct self-replicating habitats. These habitats can be best envisioned as huge walled gardens inhabited by thousands of people. Each garden would have a library which would contain the information needed to construct a new garden from tools and materials found within the garden's walls. The garden walls and construction methods would be of several different types, allowing such gardens to be built on land, underground, in space, or under the ocean. Such gardens would have the capacity to seal themselves to become environmentally and economically self-sufficient in the event of economic collapse or global warfare and the attendant environmental destruction. "

    And: http://www.pdfernhout.net/reco...

    And here: http://pcast.ideascale.com/a/d...

    But many others have discussed similar things, so just another voice in the choir in that sense. If Musk really reflects on these issues (other than being another Mars fanboy) he will see that there are many possible avenues to decentralization and resiliency, of which Mars is just one. As we gain knowledge and experience in creating such systems, then we can disperse farther and farther to deal with bigger and bigger possible disasters (including the ones you point out about gamma ray burst or wandering neutron stars).

    Also something I've been involved with, but has since became more broadly "Open Manufacturing" and the maker movement: http://openvirgle.net/

    So, generation ships etc. are interesting ideas, and they all fit into a large general picture of possibilities.

    Still, for all that, making the Earth work well for most everyone (zero emissions cradle-to-cradle manufacturing, better healthcare and nutrition, a global basic income, better education for all, indoor agriculture, new power sources like dirt cheap solar and hot and cold fusion, and so on) is a good first step towards knowing how to live in space, especially given we are already on what Bucky Fuller called "Spaceship Earth". So, I see no big incompatibility between trying to make the Earth work for everyone and preparing for a future where there are quadrillions of people living in self-replicating space habitats throughout the solar system and ultimately the galaxy and beyond -- perhaps even into other dimensions and realities and simulations? Of course, there are philosophical issues still about all this about meanings in life and so on.

    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.

  12. Agree with the sentiment, disagree with details by lazlo · · Score: 4, Interesting

    On the one hand, I think his number is off, or at least lacking detail. There's significant evidence that around 100k years ago humanity went through a population bottleneck of around 10k humans, so that seems like compelling evidence that a 10k population at least can contain sufficient genetic diversity to allow a species similar to humanity to survive. If you need a million hands to do work, then you could have those 10k people generate offspring, or you could augment their productivity by a factor of 100, or a combination of both, but as for moving people (or genes) from Earth to Mars, you should be able to get away with only moving 10k and still have at least a reasonable chance of being a back-up to our one planet egg basket.

    Then there's the idea of needing to send 100k ships to Mars. Unless you're just swimming in delta V, then you should probably launch ships at or near the transfer windows that happen every 26 months. If you're sending a ship every window, then those 100k ships will take over 200 thousand years. A lot can happen in 200,000 years. Like really, a whole lot. If you're sending 1000 ships every launch window, economies of scale work really well for orbital transfers, and you'd be really a lot better off sending a ship 1000 times bigger. It'd still take 200 years, which is still a long time, but not nearly as long as 200,000. And if you only need 10k people, you could send 1000 at a time for the next 20 years, which while still seeming extremely optimistic, at least sounds within some bounds of rationality.

    But maybe it's harder to get people interested in reasonable and achievable, but difficult goals than it is to get them excited about the unrealistic monumental ones. Sitting on the couch watching National Geographic, it's a lot more fun to say "I could totally go and climb Mt. Everest myself, I should do that!" than it is to get off the couch and go jogging for 15 minutes.

    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.

    > I don't know what technology could get a ticket to Mars from the Earth down to say $100 USD,

    I do, but then I wrote a textbook about space systems engineering [ http://en.wikibooks.org/wiki/S... ]. It's a combination of self-replicating automation, extracting local materials and energy everywhere, and a space elevator network.

    * It would be very expensive to haul all the equipment you need to Mars in order to live there. Instead, what you want to send is a starter kit of basic machines, and use those to build other machines, until you grow big enough to make the final equipment (habitat domes, etc.). You prefer to make this starter kit as automated as possible, since you won't have the facilities to support people until later. You start on Earth, and build a starter kit that grows to a full factory. That factory builds a second starter kit that gets launched to orbit, where it grows to a full factory. In turn that one sends a starter kit to Phobos, and then finally the Phobos one sends one down to Mars.

    * All of the factories run off of local solar energy and process local materials to make most of the new products. A few percent will need to be imported parts, because they are too hard to make, or use rare elements. At each location you build up greenhouses, habitat modules, and processing plants. One of the locations is a "Cycling Mars Transfer Orbit", which goes back and forth from Earth to Mars. So instead of sending 10,000 Mars Colonial Transports carrying 100 people each, you build up a mining colony/transit hub that makes multiple trips, carrying people each time.

    * A rotating elevator (Skyhook or Rotovator) can provide about as much velocity change as a rocket stage. A series of them in Low Earth Orbit, High Earth Orbit, and Mars Orbit can provide the velocity changes to hook up with the mobile mining colony, and then put you down on Mars.

    Such a system would be low cost to build and run, but you need enough traffic (like 10,000 passengers a year) to justify building it.
