MIT Study Finds Fault With Mars One Colony Concept 269

MarkWhittington writes The Mars One project created a great deal of fanfare when it was first announced in 2012. The project, based in Holland, aspires to build a colony on Mars with the first uncrewed flight taking place in 2018 and the first colonists setting forth around 2024. The idea is that the colonists would go to Mars to stay, slowly building up the colony in four-person increments every 26-month launch window. However, Space Policy Online on Tuesday reported that an independent study conducted by MIT has poured cold water on the Mars colony idea. The MIT team consisting of engineering students had to make a number of assumptions based on public sources since the Mars One concept lacks a great many technical details. The study made the bottom line conclusion that the Mars One project is overly optimistic at best and unworkable at worst. The concept is "unsustainable" given the current state of technology and the aggressive schedule that the Mars One project has presented.

    Antarctica is the closest environment to Mars that we have. Maybe we should try to get a self sustainable colony there using the same materials we would send to Mars?

      Except there's oxygen and water in Antarctica, and those would presumably be some of the biggest challenges.

      • Mars should have loads of water, you just need to drill a big whole or melt it. Also, worst case scenario you get Oxygen from the water as well. I would think that it might actually be the other parts of our atmosphere that are harder to recreate. You ?cant? just breath pure oxygen. And I hear that we have yet to find a good portable solution to all the radiation you encounter outside of the atmosphere.

          You can breath pure oxygen perfectly fine, especially when you lower the atmospheric pressure. On Mars, it would make total sense to breath pure oxygen at 1/5 earth atmospheric pressure. It's also what mountain climbers use to compensate for the pressure drop.

          The real issue is fire danger - anything combustible might spontaneously catch fire, so all materials in such environment would have to be fire-resistant. That, or you must wear a helmet all day.

              Their issue was the pure oxygen at sea level pressure.
              pure oxygen at 1/5 pressure is still a high density compared to sea level pressure of 15 lbs / sqIn.
              Something closer to 1 lb / sqIn would be the right density to prevent any flash up and provide our normal Oxy saturation provided you have a way to balance or remove CO2 from the container.

              Do read "How to colonize the Galaxy in 8 easy Steps."
              It's still relevant today even with the changes in technology in the last 20 years.

              • Oddly enough, according to the article, one of the criticisms of the project is that there will be too much oxygen, not the lack of it. They plan on growing their own food, which means the plants will need to intake CO2. There will not be enough humans / animals to convert oxygen into C02. Over time, 62 days according to the article, the amount of oxygen will go up and the plants will die off, and with no food source the humans will die.

                • But wouldn't periodical burning of something made mostly out of carbon fix that, at least until enough humans arrive?

                  I'm not saying it has to be a bonfire or even a candle lit dinner... but a small object, burned in a burning chamber of some kind?

        • Mars has lots of water in the same sense that earth has lots of gold. Getting water on Mars is not just a matter of digging a well or picking up large, pure ice chunks off the surface. It's more akin to industrial mining.

          • Two words: Ice cap.

            We know that Mars has large chunks of solid water on the surface - depending on your chosen colony site collecting more water could very well mean just stepping outside with an ice axe and chopping a block out of the glacier.

            • Nope. Those chunks of ice in the ice caps are actually dry ice (CO2), not water. To get to the water, you have to dig down a ways for it, and it's mixed in with dust and iron oxide.

          And how do you replace the drill bits? How do you keep your drilling machine moving - are you making all of its its consumable / wearable parts? How do you get the materials to patch leaks in your pipes as they arise, fix your broken valves, fix your pumps, and a whole host of other issues? How do you produce the power to melt the ice in a sustainable manner? If its nuclear, how do you refine the fuel? If it's solar cells, how do you make them to replace them when they break? If it's heliostats, how do you make the control electronics and the motors?

          And for every one of those things, how do you make the raw materials for them, and the hardware that makes it. And for each of those raw materials, how do you make its raw materials and the hardware that makes it? And for each piece of hardware... you get the picture. Modern human technology is built on IMMENSELY large intermeshed technology trees. Sure, with a huge multi-hundred-billion dollar research project to compress it down you might be able to bring it down to say 1% of its materials / parts, but it's still going to be a massive technology tree.

          And of course, you have to find all of the base elements on Mars, in quantities that can justify mining. And of course they're not going to all be next to each other, so better get started on your highly efficient planet-wide transportation system.

          And yes, efficiency really, really matters, every step of the way. If your solution to something is to use some Super Universal Plasma Centrifuge Refiner to separate out elements from ore and some Super Universal Molecular Assembler to make whatever chemical you need at a rate of a few grams an hour, and some Super Universal 3d Printer to print out whatever pieces of whatever spare part of whatever type every few days, and a Super Universal Assembler of robot arms that can put anything together, and to feed this whole chain you've got the planetary-wide mining and transportation system and extensive power and consumables needs and part wear, then you're on an irreversible downward slope. And the equation gets way harder once you throw humans into the equation because their needs are just so great. The simple fact is, you not only have to reproduce Earth's tech trees, but you need to do it efficiently.

          The scale of the challenge of true indepence from Earth is such that I really have trouble envisioning achieving anything even close in the next several hundred years. Now, spare part imports and the like, while producing your own food, water, oxygen, and maybe a couple types of bulk construction materials cast into a couple commonly needed standardized forms? That may be more acheivable. But you're still going to need heavy rockets shooting up parts and hard-to-produce raw materials to you at regular intervals, or your "colony" will enter an irreversible downward slope, and "human willpower" from the doomed colonists isn't going to conjure up, say, a couple tons of neodymium or a self-sustaining CPU manufacturing facility.

          • Great post. I would only like to emphasize that we don't have to build a 100% self-sustaining colony from the first launch, and that a Mars base is not a closed environment. So, two comforting factors:

            1. Importing even only a few small key components (like CPUs or nuclear fuel) can cut a huge part of that tech tree you mentioned, until the local capabilities are improved.

            Just remember that a lot of that is due to economic efficiency, not because the resources aren't available locally or because there weren't other material choices or simpler technology that would have gotten the job done. You don't need to ship 14nm CPU process technology, if you could replicate the 3200nm, ~20k transistor technology of 1978 you'd have an 8086 chip that is still a decade more advanced technology than what got us to the moon. Instead of neodymium you could probably use a gas laser or iron magnet for most applications, using only common elements. When we look at how we could build a Mars outpost using our most advanced technology and materials it's from our perspective here on Earth where the sourcing and manufacturing is cheap and easily available while the delivery is extremely expensive. If you flip that around to say what's the lowest tech, most easily sourced and versatile alternative they could do locally it might turn out that the must-have part of our tech tree isn't that big after all.

      • If the goal were to simulate and test the feasibility of a long-term Martian outpost, that shouldn't be too hard to replicate. Mars has the necessary elements, just not as easily accessible as on Earth.

        Create an isolated, pressurized base where the only source of oxygen comes from internal systems, not outside. Place a "factory" by the outpost that pulls in water from the environment at the same rate as it would on Mars (obviously it would discard most of it); crack some of the water to get the necessary ox

        • Harder to test would be the problems caused by low gravity, lower atmospheric pressure and increased radiation. Well, for the latter I guess we could just open the ozone hole for them again ;-)

          Low atmospheric pressure would be easy enough to test with a (de)pressurized base on earth but then again on mars presumably you could
          pressurize the colony to the same pressure as earth.

          Increased radiation is also easy enough to test if you really wanted to. There are plenty of sources of radiation from tanning beds to radon to
          radioactive waste. We have already done plenty of those experiments (intentionally or unintentionally) on earth and pretty much know the
          outcome of those.

        So it should be easy. We should require anyone who wants to move to mars to spend 5 years in antartica.
        Antartica is a cake walk compared to mars. My guess is that a majority of those people wouldn't make it
        five years and might reconsider their desire to go to mars.

      • And despite all those advantages in Antarctica, we've only be able to establish seasonal colonies in the continent, and those have been entirely dependent on re-supply from outside for almost all their basic needs. And in Antarctica resupply is a infinitesimal fraction of a cost of what it would be in Mars.

        Prove to me that we can establish a permanent, self-sufficient settlement in Antarctica first, and then we can consider Mars.

        • Antarctica has a different set of problems, mostly tied to horrendous cold and weather. Mars has virtually no atmosphere, making both of those a non-issue for anything that generates heat locally. Insulate a habitat from the ground and you'll probably need to start dumping the buildup of body heat before long. And those 400mph winds during a Martian windstorm still have less force behind them than a 3mph breeze on Earth: 99.3% lower air pressure also means 99.3% less wind pressure.

      • Not really - there's plenty of water and CO2 on Mars, and plants are pretty good at converting those into oxygen without the help of any high technology.

    • Not really. Antarctica is bitter cold and has horrendous weather. Mars meanwhile is more "termperatureless" due to the near-lack of air, insulate yourself from the ground and you're essentially in a giant vacuum thermos. It also has negligible weather other than occasionally "dusty" thanks to that same lack of atmosphere. A 400mph wind may gradually sand-blast exposed surfaces, but there's substantially less force behind it than a light breeze on Earth. And our rovers have pretty well established that t

    Mars One is a commercial TV-show. The goal is to make money for the producers. The entire project is financed by making television about the endeavor. Actually reaching Mars and building a sustainable colony there are secondary goals. The project can be a succes without ever launching a single rocket, as long as people are willing to pay for the show that is produced around it.

    Although I'm a bit cynical about the probability of reaching Mars I think the idea of financing a spacemission by selling TV is pure genious. The landing on the moon is one the highlights of 20th-century television. If so many people want to see it there must be an opportunity to make money.

        The big problem is all the rocket jocks think that getting to Mars is hard part and they have the idea that since biology and ecology are "soft" sciences that those are just details that will work themselves out. Until someone starts a long term self-sufficient colony on someplace like Antarctica, its really hard to take an Mars colonization plan seriously.
