NASA Offers Reward for Extracting O2 from Moondust 276

DoubleWhopper writes "Break out the duct tape and paper clips. NASA has announced a $250,000 reward to the "first team of scientists to invent a way to extract breathable oxygen from lunar soil". Wired reports, "Inventors who attempt the Moon Regolith Oxygen (or MoonROx) challenge will have just eight hours to extract at least 11 pounds of breathable oxygen from a simulated form of lunar soil.""

          This is like the 4,928th time I've said that Slashdot's average reader is rather uninformed about the US Patent system.

          35 USC 105 [uspto.gov]

          Note that 35 USC 102 is novel inventions, 103 is non-obvious inventions, 104 is foreign inventions, and 105 is inventions in outer space. It's no more than 2 statutes away from the critically misunderstood non-obvious inventions statute.

          I apologize for sounding like I'm ranting on you. It's not you, it's just that it's really hard to have a positive, upbeat attitude when disseminating information about the US Patent system around Slashdot. Put yourself in the shoes of someone who IS informed about how the patent system actually works and I hope you'll understand.

        The soil on the Moon basically consists of minerals including aluminum, calcium, magnesium, oxygen, silicon, and titanium. So let's take the first one, aluminum.

        It's atom has 13 protons right? So just take those 13 protons and split them up into 13 Hydrogen atoms. Then take those 13 hydrogen atoms and add them together to make 1 Oxygen atom...with 5 extra protons that can be put aside for furture oxygen building. So from just 1 aluminum atom you get 1.5 Oxygen atoms!
    • Amen, brother. The risk-reward ratio is way too low on this one. Basically, they're asking for a technological innovation on par with the light bulb, and they want to give a prize less than the lab assistants wages necessary to even seriously look at the problem for 10 years.

        That's a bit of a stretch, isn't it? Generating light by means of electricity in a fashion that's repeatable by manufacturing techniques of the day and cheap enough for the common man was an incredible achievement and required significant technological advance for the time. We already have many industrial processes for extracting oxygen from oxides (often used for purifying oxidized metals, not recovering the oxygen itself). This prize is just for developing a system that packages those processes in a way that they can be used on the moon. Furthermore, it's not like NASA is asking the developer to warrant the stability of the process or any such thing, just come up with a viable method. Years of development will come afterward, and it might not even be with the prizewinner's system if the second runner up, six months later, comes up with a system that works better.

Maybe that's NASA's plan: convince researchers who want to take the prize home themselves to try this with company funding, give the prize to the researchers, license the patent from the company at a cost lower than doing the work themselves, leave the company to make money from other commercial spacefaring entities.

        And on this contest it sounds like the byproducts will be aluminium and silicon... and those will be discarded. Which is why I think the contest is poorly worded, and will lead to an inferior 'winning entry'.

        Why throw away ultra pure silicon and aluminium just to get oxygen? With a slight increase in complexity you get a sweet refinery that can produce O2, Si and Al, as well as iron and titanium in much smaller quantities.

        Sample rock break down, I figure this is *fairly* representative, but I just picked a random rock from the below link (by weight %):

        CaO - 20.57
        Na2O - 0.384
        MgO - 0.53
        Fe - 0.2
        Ti - 0.018

        Here is a page on the moon rock samples:
        http://www-curator.jsc.nasa.gov/curator/lunar/lsc/ index.htm [nasa.gov]

        Each link is a PDF which contains, amoung other things, a breakdown of the mineral composition of the rock in question.
        • I was curious, so conversion to mass percent:

          SiO2: 0.53 * 44.94% = 23.8%
          Al2O3: 0.47 * 35.71% = 16.8%
          CaO: 0.29 * 20.57% = 6.0%
          Na2O: 0.26 * 0.384% = 0.1%
          MgO: 0.40 * 0.53% = 0.2%
          -----------
          total = 46.9% oxygen by mass in that rock. I couldn't find how much moon dust would be available for processing. I wonder the percent yield necessary to win the contest . . .

      The challenge is to rip those oxygen atoms from the silicon and calcium atoms. This is hard because they are tightly bound. Moreover, I doubt NASA would be interested in any process that consumes some other non-moon-available chemical (trading 5 lbs oxygen for 10 lbs of a reducing agent). I suspect that some sort of electrolysis [kyoto-u.ac.jp] might do the trick, but even that might be outside the power budget.

      The carbon would be reacted with various metal oxides present in lunar soil.

    The lunar environment is so radically different there that it changes a lot of the design parameters. Structures weigh 1/6 as much there as they do here. Build a structure that is strong enough for Lunar gravity and it'll collapse here. You've got both a 250 degree F heat source and -250 degrees heatsink readily available on the Moon which makes for a nice heat engine but again, it only works on the Moon.

      I would suggest that you look more at this article from New Scientist:

      http://www.newscientist.com/article.ns?id=dn7403 [newscientist.com]

      The big deal is that you are going to be given a lunar soil simulant (they say that getting the real stuff is just too expensive to do anything but a final proof test with) that comes from a volcanic ash deposit near Flagstaff, AZ. For a small fee a research team can obtain samples of this simulant for experimental purposes.

      It must put out at least 5 kg of oxygen (assuming that the time to produce this is limited to a short period of time... 24 hours or less), and the whole device must weight less than 25 kg. I would also guess that space considerations are also something to worry about, but that the weight of the device is a bigger deal.

      I guess the Wired news article says 11 kg in 8 hours.

      In short, it is something that should fit in a foot locker that astronauts could pull out and set up once another lunar mission actually occurs.

      This is a bigger deal than the tether challenge, and something that has some hard short-term practical applications in the space industry. Also, the $250,000 is something you can pay a research team to do more than hold a pizza party afterward with when you win. If you already have a minerology lab, this would be worth pulling a couple of interns/lab assistants over to wrap their energies around. And potentially some very nice contracts in the future if NASA gets off their behind and gets back to the moon.
