Deep Space Industries to join the asteroid gold rush

    A new space company will announce plans to mine the minor planets at a press conference in Santa Monica, California, tomorrow, 22 January.

    Deep Space Industries intends to build a fleet of commercial asteroid-prospecting spacecraft that can harvest and process these chunks of space rock.

    Until the 22 January event, the company's founders are keeping a tight lid on further information about their plans to plunder precious resources for profit.

    But their targets are likely to be a class of minor planet called Near-Earth Asteroids which have orbits bringing them close to us on their journeys around the Sun.

    They will want to tackle a type of asteroid that is like a crumbly pile of rubble, similar to Itokawa which was visited by the Japanese probe Hayabusa in 2005, rather than the more solid objects. That is simply because it will be easier to get at their assets.

    Another company, formed from an assortment of tycoons, has already emerged in 2012 to announce similar space mining plans, convinced that even a small asteroid can be worth billions of dollars.

    Planetary Resources is a US company led jointly by Eric Anderson, who also heads Space Adventures that has already sent several wealthy clients to the International Space Station.

    Anderson is co-founder and co-chairman of Planetary Resources with Peter H Diamandis, backed by famous investors including Eric Schmidt and Larry Page of Google. Avatar director James Cameron is an advisor.

    Got to love the hubris. What are the crises of the 21st century ? Permanent depletion of aquifers. Catastrophic loss of topsoil.
    Massive irreversible climate change. Overwhelming over-population. Enormous and growing inequality. Extinction of the last fossil fuel
    reserves with nothing to replace them. Scandalous military spending and weapons build up. What do we need ? Space mining ! Dum De Dum! To hell with all that boring stuff, a fleet of asteroid mining robots - thats the future.

    Heh, it will probably never be fully realised but I can't help but get excited when I read about people trying stuff like this.

    Scary. Getting worse by the day. Handing over control of more and more of the earth's resources to fewer and fewer people. So they
    can devote it to their private whims.

    http://www.theregister.co.uk/2013/01/22/deep_space_industries_asteroid_mining/
    The venture says that it will have its first class of 55lb (25kg) "FireFly" probes ready for action by 2015, hitching a ride on other commercial launches, and during their six-month missions will explore Near Earth Objects (NEO) for useful materials.

    The second generation of larger probes, dubbed DragonFlies, will be sent off by 2016 to land on and mine asteroids, producing around 60lb to 150lbs (27kg to 68kg) of finished cargo on a two to four-year mission.
    ...

    Gump explained that the probes wouldn't just be looking for metals, but also for liquids that can be broken down into oxygen, hydrogen and methane and used to refuel satellites once it has been brought back into the Earth's orbit, adding another revenue stream.

    "It cost around $20,000 per kilo to get the fuel for a geosynchronous satellite into position, we're sure we can supply it more cheaply than that," he said. "If you can then extend the lives of these satellites, then operators will be able to save millions of dollars in costs."

    Key to the success of the project will be DSI's patent-pending 3D printing technology, dubbed the Microgravity Foundry. He said the tech will make it possible to extract pure nickel blocks from asteroids. The process sees powdered nickel ore fed into the system, which is then formed into units of solid metal, and can also be used to make tools and replacement parts.

    Nickel at the moment costs 17 dollars a kilo:
    http://www.metalprices.com/p/NickelFreeChart/?weight=KG&size=M&theme=1011

    Assuming a dragon fly probe weighed just 50kg it would cost about a million dollars to put into orbit. As for manufacturing costs:

    http://www.spaceflightnow.com/news/n1201/29hayabusa2/

    Japans Hayabusa2 probe ( no advanced mining etc) cost 200 million dollars.

    If a dragon fly managed to mine a full 68kg of nickel and bring it to earth, it would be worth a whopping 1156 dollars. After 2 years.

    Price:
    Manufacture - optimistic 50 million
    Launch - optimistic 1 million
    operational cost ( ground team over 2 years) optimistic 5 million
    total 56 million dollars. Result : 1156 dollars worth of nickel. This is a scam pure and simple.

    Nickel in LEO costs a bit more ;)


  • Registered Users, Registered Users 2 Posts: 325 ✭✭ThatDrGuy


    Nickel in LEO is worse than worthless. There is absolutely no demand for it and the last thing we need is more junk in LEO that satellites have to avoid.

    I had the thought that asteroids would be richer in heavier elements that are rare in the earth's crust, because the heavier materials sink to the core. But even 68kg of platinum would only be worth about 4 million dollars.

    actually it's worth a lot more at GEO

    you can make structures out of it , 3D printer and all that

    you can use it as reaction mass

    you could make flywheels out of it for gyroscopic attitude control

    it could be used to make shields , mirrors

    The Mars Curiosity rover used 300Kg of inert ballast during it's descent



    on the ground it's pretty worthless allright


  • Registered Users, Registered Users 2 Posts: 325 ✭✭ThatDrGuy


    Unless asteroid nickel is actually unobtainium I somehow doubt it would be worth hundreds of thousands of times the stated nickel prices that mining it would require. Ballast ? Really ? The end product of the most advanced mining project in the history of humanity. Can you imagine the poor guy flogging this sales pitch. Market? Why yes. Where is your market ? I have one word. Just one word... ballast. Space seems to be the new frontier for economic stupid ( it used to be the internet) Put online in or after a word gave it a veneer of economic gospel, no matter how daft. The price of nickel reflects its current utility relative to its scarcity. Not very high to put it mildly. Quoting it's utility as a input in a vast chain of space manufacture and supply that doesn't exist is hardly convincing. Its putting the space cart ahead of the space horse. I found the video hilarious and scary at the same time. Brought out the vision of space billionaires living in low density housing in an orbiting forested park while a conflicted polluted overpopulated earth rots beneath them.

    Has my comment regarding ballast been misunderstood? I was suggesting that those ballasts were far from inert. Wrong forum I know, which way to conspiricy theories?

    but what if launch costs keep falling, and all the hardware is used over and over again, and what if they mine more than just nickel

    a boeing 747 will cost over 300 million to buy, and who knows how much to run and service, but I can fly accross the atlantic and back for less than 1000 euro

    the same thing will happen with all types of space technology, its only a matter of time

    Yes there are cheaper ways to orbit, but no one has invested significant resources into them. Rocketry will have a minimum cost. Which creates a viscious cycle - satellites could be a lot cheaper if it cost 1/10 the amount to launch them

    Don't mean to drag the thread off topic but have to agree here :(

    Another video uploaded by DSI after the conference shows a Q&A. About 11 minutes in one of the lads on the panel 'addresses' sharing and distributing the resources that'll be mined/obtained (apparently if they get the investment they're looking for they hope to beaming solar generated electricity down to earth by 2025). Just worrying that the people who'll be in control of all these resources reckoned that the best method of sharing resources throughout the earth is demonstrated everyday through the 'free enterprise system'.

    In other words he meant "No, we're not going to distribute resources with everybody". Which is upsetting cause they really made themselves out to be doing the planet a favour in their conference.

The advent of 3D printing really does a lot here as it means that practically any component can be manufactured on board. So basically once you have the station built, it can build its own fireflies and send them on, massively reducing the cost of sending thousands (if not millions) of drones into space.

    Hi Zeroy, infastructure is an investment. There will be millions of people using the infastructure and they can recoup a lot of the cost. As fossil fuels become prohibitively expensive high speed links are vital to try and maintain industry and transport. Every billion spent on mars is a billion not spent on addressing very real problems on earth. Thats fine if that billion comes from defence spending but that seems to be sacrosanct.


    Growing crops on mars as this info graphic suggests is 10 kinds of crazy.

    Growing crops requires:
    Soil:

    Martian soil :
    Has no known organic components ( no earthworms, nitrogen fixing bacteria etc)
    Is mega toxic: full of oxalate and heavy metals such as cadmium and arsnic
    Is highly reductive iron oxide.


    Light & Water:
    All the water is at the poles that recieve next to no light. Most of the light
    is at the equator which has no water

    C02:
    Humans make, but balance quite delicate

    To farm mars you would have to import everything. All the nutrients. All
    the water. All the organic gaia. You would need constant shipments of these. The only input mars offers is light and some gravity. Massive athmospheric condensers could extract some water but you would have to cover enormous areas of mars for only a few acres of farming. Farming is much easier in death valley. Death valley is a lot less hostile to human life too. Yet there are no plans that I know of to farm death valley. Why ? Because it is economic lunacy. But put Mars or Space in a plan and even though its a million times dafter the economic lunacy seems to vanish.

    Seamus 3d printers are not replicators. They cannot perform magic or violate the laws of thermodynamics. If the tech existed to replicate a space probe whole without any inputs from earth, we wouldn't need space mining.


  • Registered Users, Registered Users 2 Posts: 959 ✭✭✭ZeRoY


    All in its own time ... the madness starts when they mention doing this in the next two decades, then I agree. But otherwise, it will happen, totally convinced (maybe not on Mars).

    wrong, try again

    maybe, we won't know for sure untill we look. my guess is the first people will land somewhere between the poles and the equator

    the reason I used the example of a 747 is because it is a good example of a reuseable transport that cost millions to build and service, but it is used every day by average people like me, this is what needs to happen with rockets

    the space shuttle is the exact opposite of a 747, it failed at being reuseable

    right now spaceX, blue orgin, and skylon are working on making space flight a cheap every day low cost business, I think they all have a good chance of success, but I think spaceX are ahead of the pack for now but that could change

    once all the hardware is reuseable then the costs will drop and Mars and the Moon will be easy to reach

    Is a hammer made from plastic that same as one made from hardened steel?
    Can electronics be made in a 3D printer?

    Can a 3D printer make anything more useful than a plastic shoe or wrench or cup or screw. I doubt it.

    What's the purity of nickel on asteroids?

    And again, I don't know a lot about this, but are they not looking into printing electronics;



    My understanding of the vision for 3D printing was always more the idea that a part of your hoover at home breaks, instead of throwing it out you can just google the part and print it off. Less so making things like socks and hammers. Wouldn't it work if they just designed the fireflies/satelites/robots printable in the first place?

  • Registered Users, Registered Users 2 Posts: 68,317 ✭✭✭✭seamus


    3D printing isn't limited to producing one-piece plastics. That's the current limit of home applications, but primarily because the process and the raw materials are cheap and easy to work with.

    On the scale of billion-dollar budgets, complex machinery can be "printed" component-by-component and assembled automatically. It's unbelievably short-sighted to think that 3D printing will only ever be able to print simple one-piece plastics. There have already been prototypes of printers with multiple "cartridges" containing different compounds which allows for a complex item to be printed in one move.

    No, they're not replicators, but they're planning to mine minerals. There's your raw material from which you build more equipment. Anything which isn't easily mined or produced in orbit can be periodically shipped up from earth. Building equipment on earth and shipping it up is more troublesome because stuff can break. Even just shipping the components up unassembled is better than having it pre-assembled.

    Actually I like your sock example, because that's a good example of the kind of process I mean. You can produce nylon fibres - that's your 3D printing - then have the socks woven by machine. Et voila; Socks, produced automatically by the facility. I'm not sure what use nylon socks would be in orbit, but it could be done.


  • Registered Users, Registered Users 2 Posts: 4,632 ✭✭✭maninasia


    Well yes but then you would have to ship the nylon to make the sock in the first place..and the chips etc etc. Materials matter, and the combination of materials made under different processes at different pressures will vary enormously in their usefulness and application.

    I think some sort of microfabricating facility will be useful in the far future, but not for decades and decades. You would want a bunch of generic switches, ICs etc which a robot could stick together for you and which would have updatable firmware. Again though you are not actually going to be making the ICs and many of the components on a spacecraft.

    The energy to needed to produce these tools and also to refine the materials to make the tools (such as nickel), especially if they require high temperatures and pressures, is also a big problem. The raw material is not just sitting there ready to be used on an asteroid. It needs to be refined and purified or else just drop shipped back to Earth.
