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."
Mars does not have a molten iron core, and hence doesn't have the cool magnetic field that earth does. That magnetic field does a LOT to protect our atmosphere from getting stripped off, not to mention protecting us from radiation.
Screw Mars. Spend all that money on making it nice HERE. We have the means. We have the tech. We could have a star trek utopia right here... Free education, opportunity through small businesses, cheap housing, plentiful energy. We could have all that right here if we just put a smidge of effort into it.
Take all that money and just pay off 5% of the population's houses. Those people, now freed from having to grind on the treadmill for their housing, could start small businesses... circulating money in the economy. It doesn't need to be much. Start a taco truck... Employ a few people... We'd have zero unemployment and a lot more happiness. The economic repercussions would be staggering.
A lot of human suffering is because a few assholes ruin it for the rest of us. How about we fix THAT? Screw mars...
