NASA Offering Contracts To Encourage Asteroid Mining 153

An anonymous reader writes "Two private companies, Deep Space Industries and Planetary Resources, have received contracts from NASA to study asteroid redirection and will pursue their plans of asteroid mining. From the article: "Deep Space Industries is planning to build a number of dense spacecrafts called FireFlies, and they plan on sending the satellites on one way missions to gather information about the density, shape, composition and size of an asteroid. They also have plans to build a spacecraft called Dragonfly, which has the purpose of catching asteroids. The asteroid material will be collected and returned to Earth by 'Harvesters'. Planetary Resources, on the other hand, plans to build a number of middle sized and small telescopes that will be capable of examining asteroids near the planet Earth for economic potential. They already have the telescopes Arkyd 300, Arkyd 200 and the Arkyd 100, each having its own specific systems."

  • Anything obtained will be overpriced and just a general novelty for quite a few years. I could see asteroid mining to be relevant for rare-metals once we improve the cost-effectiveness of venturing into space. But for now, the price point is just too high. And what are these "companies" even doing in the meantime? Hmmm...

      Space-procured Palladium and Platinum has the potential to make space-based mining possible. If you could put an asteroid in earth orbit containing a couple of tons of platinum group metals and extract them (that's the tricky part) you would own the global market for those materials.

        The global platinum market is only $10 billion/year, which is not a lot of money to fund an asteroid mining mission, and to safely land the platinum ore on the ground.

          I think that the "platinum group metals" the previous poster talked about, consists of more than just platinum.

          • That's also discounting that the platinum group metals are highly useful for industrual catalyst material, which would be indespensible in space-based manufacturing-- It's necessary to produce bulk quantity nitric acid, and is used to make many kinds of hydrogen fuel cell.

            Part of the reason why 'World market for platinum" is so small, is because the metals are hard to extract-- they tend to form in useful deposits only old vocanic areas, which have very hard stone matricies that need to be mined. EG-- it's

            Correct. But I didn't feel like doing an hour's worth of research for the most accurate number. The Rosetta mission cost EUR 1 billion, and it only managed a one-way 10 year journey of a 100 kg payload on a comet. A mining mission needs to be round-trip, and would easily involve 100 tons of equipment. Cost would run in trillions of dollars easily. Even if you include all platinum group materials, it wouldn't be worth it.

        From a medium-term perspective, I think iron, hydrogen, oxygen and carbon would be more useful as they would then be available for space-based construction, allowing us to expand our space resources.

        • Except the earth does not have an endless supply of things to mine. We are working with finite resources that will be exhausted even faster by the ever growing world population. The newest mining technologies is what has increased the US energy production but even these technologies have some serious consequences if taken to far.

        Unless, of course, it doesn't. I figure most of this tech will have to be reinvented by whoever actually does stuff in space. That means I don't think this stuff is particularly useful in anyone's lifetime, much less our own.

      • Manned space exploration is not unique in that regard. Any field of research will lead to new ideas and new technologies if we throw enough money at it.
        • That's the paradox. Almost all of our fundamental scientific knowledge was created in someones mind at very little cost. It's the implementation of those concepts that cost a lot of money. And while a lot of people will never admit it the vast majority of technology advancements have come from the money spent on military applications. The multistage rockets that got the US to the moon also provided the technology to develop ICBM's. Nuclear weapon development advanced the underlying understanding on how to r

    Thank you!

  • TFA in the summary doesn't have any useful information and no additional links. The only thing I can find on NASA's website is an announcement back in June that eighteen studies were funded [nasa.gov]. Has something happened recently?

    Science fiction authors have totally solved this problem a zillion different ways. They all share certain features. First you go to the asteroid. Second, you set up some sort of mass driver on the asteroid or ion driver, ideally one that uses solar electricity or heat and not imported fuel, but if you don't mind a bit of radioactivity, propulsion by nuke is OK (Orion).

    Depends on the mass of the asteroid as well, and how long you want to wait to get it home, and how much of it you want to have left when you get there. If you don't mind waiting a VERY long time, you could even use an angled light sail for propulsion. Third, you drive it home, or rather, have your fully automated computer tools do it for you. Fourth, you get it into Earth Orbit and then use it to threaten the hegemony running Earth, insisting that they send you dancing girls and exotic foods or you'll drop it on their heads -- it makes you way more money than actually selling the metal.

    Optionally, you can have your robots smelt the asteroid in place first, using large mirrors to concentrate solar energy to melt the asteroid rock into slag plus metal, perhaps even collecting the slag (with a thin metal coating) to use in your linear accelerator or solar heated rocket as reaction mass. Some asteroids are really comet heads and might be covered with solid gases and ice and might support making real fuel on the spot as well. And fusion would no doubt shift the plan a bit as well.

    But the final stage is always to drop them on Earth, not use them for good. Otherwise there isn't any real plot. Sometimes they don't even bother dropping them per se, they just fall by accident. But nobody can resist an umpty teraton-of-TNT explosion: not invading space aliens, not Dr. Evil, not the asteroid mining company's board of directors, not even the grizzled old asteroid miner whose sainted mother was put out onto the street to starve during the housing riots of 2057.

    • by khallow ( 566160 )
      So what you're saying is that sci fi writers have not only solved asteroid mining, but also overpopulation and the productive employment of psychopaths. Win-win-win all the way around.
  • The goal isn't to bring the resources back to Earth.

    Sure a astroid made out of solid gold might surpass the break even point at current prices you'd only have to bring back more than 50 pounds of gold per million dollars spent to break even. But there are also diminishing returns, too much new gold and the price will crash.

    Water and plutonium, which is what the article says they are focusing on, are worth far less than gold.

    Having water and plutonium already in orbit means missions can be designed to use th

    • by tomhath ( 637240 )
      The problem is that those resources are in the asteroid's orbit, which isn't useful to any mission other than one going to the asteroid. And putting it into a different orbit would be much more difficult than an Earth launch.
      • > And putting it into a different orbit would be much more difficult than an Earth launch.

        This is factually incorrect. Using electric thrusters, and Lunar gravity assist, you can retrieve asteroid rock for about 2% of the rock's mass in fuel. Since part of what you can extract from the rock is more fuel, the mining operation is self-sustaining until the equipment wears out. A reasonable estimate is you can fetch 200 times the mass of a fueled space tug over it's life.

        • by tomhath ( 637240 )
          And how does that compare to getting the same amount of rock from Earth? Just because a science fiction writer made up a story about it doesn't make it feasible.
        • "Using electric thrusters"

          And about a thousand-year burn? Electric thrusters have crap thrust. Fantastic specific impulse, but crap thrust. And even a very small asteroid is going to be in the multi-kiloton range.

    • You are entirely correct, except you misused the word 'worth'.

      Worth is dependent upon location. Gold buried under 600 tons of radioactive lava is worthless.

      Water in a desert is priceless.

      Water and high purity plutonium located in outer space are worth far more than gold in that same location.

      • by itzly ( 3699663 )
        Water in a desert is priceless only for people who want to go traipsing in the desert.
        • Without people, everything is valueless.

          The value of gold is only high for people. Cows don't care about gold.

          All valuation assumes that there are people in that same location. If they are not there, then the value is always $0.

          • by itzly ( 3699663 )
            Exactly. There are no people in space, nor is there much use for them. So the water isn't very valuable either.

              So the water isn't very valuable either.

              things are worth what people will pay for them

              Too Short, Didn't Read? Allow me to elaborate. There's not much use for people here on Earth, mostly we stink up the place. Space is maybe not the next frontier (seems like we should finish exploring the oceans first) but it's coming up. We are curious monkeys, and we want to know what's out there. So we're going, sooner or later, if we don't drown in our own waste first. And in order to do that, we're going to have to mine asteroids,

    • by itzly ( 3699663 )
      Of course, water and plutonium are only useful in space if there's a profitable application for them that outweighs all the overhead of mining and refining the stuff.

    • The amount of solar energy that passes closer to us than the Moon is equal to the whole world's fossil fuel reserves every minute. That's not just energy independence, that's a superabundance of clean energy, as long as the Sun lasts. I think that is worth a small amount of R&D funding. Tapping that energy is easier if you can use equipment made locally in space, rather than hauling it all up from Earth. We have no production capability in space at the moment. If we can reach the "bootstrap point",
