NASA Offering Contracts To Encourage Asteroid Mining

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."

If you're comparing the advantages of asteroid mining over lunar mining, the most likely delivery points will be LEO, Luna, and the Earth-Moon Lagrange points.

Over the long term, EML2 will emerge as a real "hub" of the Earth-Moon system, as LEO becomes more crowded with human activity.

      It's a bootstrap process. You start out with the easiest items to make from asteroid rock: bulk shielding, water, structural iron, oxygen and hydrocarbons for fuel. At that level you bring ready-made processing equipment. Then you bring machine tools, 3D printers, and the like, and start making other processing equipment. Gradually you make more things locally, and import less. About 2% of your items will either be hard to make (like computer chips), or require elements that are rare in asteroids or other space locale.

    In general the idea is that your primary market is in space, and competes with Earth-launch costs. (Such as fuel.) Then incrementally grows as what is essentially a waste product from the first production becomes a product in the second, then the third... say bulk shielding, then simple bulk metal components, then dishes/antennas/etc, then manufactured products like solar arrays. Each competes only with the cost of sending up that product from Earth into space, but eventually you have enough industry going on up there that dumping a shipment of PGMs or even nickel all the way back to Earth is a small side trip that is worth the extra income, even though it can't possibly justify all that infrastructure in the first place. At that point, you are just starting to become competitive with Earth-side mining, and the development should increase exponentially after that.

    The initial process of getting from here to that first product is also, by coincidence, the same requirements as doing interesting science.

    It might not ever be economical. But the process of finding out that it's not economical is just relatively low-cost science. Unless we're stupid, we don't have to commit any more than that to find out that it is or isn't worth committing more.

    Combined with the high likelihood of a thick layer of water-ice at the poles (for fuel) and its nearness to Earth (allowing teleoperated robots, and much easier human presence), makes the moon a reasonable place for us to get started than an asteroid.

    It's more like several tenths of a percent native iron in the Lunar regolith, and typically the particles of iron are cemented to blobs of glass created by the heat of impact. You *can* separate the iron bits magnetically, but then you need an additional melting step to separate the slag from the iron. Other than that, I agree that native iron will be a useful product on the Lunar surface.

    A chondrite type asteroid contains carbon and water (as hydrated minerals). These can be extracted and reformed into hydrocarbons and oxygen, which are an excellent fuel for *landing* on the Moon. Also asteroid rock brought back to a Lunar vicinity orbit can be in sunlight ~100% of the time, whereas a region at the Lunar pole which traps water ice would also have low sun exposure.

    Rather than thinking of Moon and Near Earth Asteroids as competitors, think of asteroid rock placed near the Moon as a literal stepping stone. It would be a place to fuel your lander on the way to the surface. By lowering the total mass ratio to reach the Lunar surface, it makes it *easier* to get there. Now, if you can extract water ice, that helps you get back to orbit from the Moon's surface. Ideally you want to do both. The rocket equation imposes an exponential mass ratio based on delta-V. If you can refuel at multiple points instead of bringing it all from your point of origin, it changes the exponential into a linear problem. That's way way better.

    > Good for you! You are proposing to build an actual von Neumann machine.

    The idea of a Von Neumann machine assumes 100% automated and that it copies 100% of it's parts exactly. We don't make those assumptions. Human labor is allowed in the Seed Factory concept, whether hands-on, or by remote control for space versions. Some parts will be too hard to make internally, like computer chips. Other parts will require rare elements that are not available locally. So those items are simply bought instead of trying to make them in-house. We think a reasonable goal is 85-98% internal production by mass, depending on location. Lastly, we don't replicate (copy our parts exactly), we expand by making parts for new machines not in the starter kit, or by building larger versions of existing machines. If you want to, you can eventually produce a copy of the original starter kit, but that is after a period of growth from the seed to the fully mature factory.

    > Any estimate on when we will see this is more than just an electronic document?

    Our Seed Factory Project [ http://www.seed-factory.org/ ] has purchased a 2.67 acre (1 hectare) R&D location in the Atlanta metro area. We are starting to install a conventional workshop, with the intent to build prototypes of the starter kit machines. We plan to collaborate with local area Maker groups and hopefully institutions like Georgia Tech. Our designs will be open-source, which is why we are using Wikibooks and similar sites to document things.

    > The real question is how many of these kind of tools together with a good smelter do you need before you can be self-sufficient and keep making your own sets of tools out of raw materials?

    We phrase the R&D question a little differently: What is the best starter kit, and best growth path from the kit to a fully expanded factory? We have a draft starter kit list at https://en.wikibooks.org/wiki/... , and it includes a lathe, mill, and press, which are basic machines, but there are several others in addition. The starter kit emphasizes flexibility by using attachments to do different tasks. The expanded factory can add more specialized machines as needed, since your starter machines can only do one thing at a time.

    > it would be nice to get a set of these kind of tools into the hands of people in 3rd world countries

    Providing starter kits for under-developed areas is one of the project goals.

    If you can build 85-98% of your stuff from local materials, it dramatically reduces how much you have to bring from Earth. That has huge leverage on what projects are feasible. However, helping people on Earth is a more immediate and larger need. So space versions will be 3rd or 4th generation Seed Factories.
