NASA Looking For "Diamonds In The Sky" 101

Posted by ScuttleMonkey from the asteroid-mining-the-next-big-industry dept.
I Don't Believe in Imaginary Property writes "Scientist Charles Bauschlicher and his research team have found a new way to look for 'diamonds in the sky'. It may not be romantic, but diamonds shine especially brightly in the 3.4 to 3.5 micron and 6 to 10 micron infrared ranges, which should make NASA's Spitzer Space Telescope the perfect tool to see them with. Though less common and more monopolized on earth, diamonds are surprisingly common in outer space and the nanometer-sized bits comprise 3% of all the carbon found in meteorites. That means that if meteorite composition is representative of interstellar dust, that dust would contain about 10 quadrillion (1 * 10^16) nanodiamonds per gram."

      Arthur C. Clarke noted that the idea that Jupiter's core was a gigantic diamond was inspired by an article [nature.com] in Nature which speculated that a solid layer observed in the compositions of Uranus and Neptune was composed of carbon liberated by intense pressure from methane.

      Laboratory experiments [sciencemag.org] mimicking the temperatures and pressures found deep within those planets suggest diamond production is indeed possible, but would be more likely to be an agglomerate mass of diamond microcrystals than the yottacarat diamond solitaire envisioned by Clarke. Uranus and Neptune would probably make for better diamond production than Jupiter and Saturn due to a higher abundance of methane and thus carbon.

      That being said, recent research suggests [newscientist.com] that Uranus and Neptune are not sufficiently carbon-rich to have produced an appreciable amount of diamond after all.

      • Why isn't anyone mining Uranus for diamonds, then? Seem that this would be the cheapest (and most profitable) space exploration possible!
        • I'm not entirely sure that would be cheap! And then if you, in a magical world far in the future, create a viable constant mining business/supply chain from Uranus, you're dealing with the fact that you're creating increased supply so the price/value of diamond by definition goes down, unless demand outstrips supply.

      Actually, diamonds probably aren't worth the trouble of asteroid mining. Crushed diamond powder is cheap and plentiful right here on earth. It's only the larger chunks of diamond that are valued much, and even those aren't in short supply. The price of diamonds is only as high as it is because a cartel of the major producers work in collusion to keep the prices up. I suppose diamonds from asteroid mining might force them to lower their prices a bit, but it's unlikely that mining asteroids for diamonds could successfully compete with earth based diamond mining.
      Quite possibly if we do end up with asteroid miners, they'll be throwing away cheap carbon compounds like diamonds, in favor of useful ores like iron or nickel.

        Yes, diamond powder is great for grinding and polishing hard things, like silicon wafers.

        Industrial diamond is manufactured cheaply. You can even find it on eBay for a couple of bucks a carat.

        The trick is getting a consistent grit/mesh/size so that you know how polished you can make your wafers.
