NASA Looking For "Diamonds In The Sky"

Posted by ScuttleMonkey on 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."

      Laboratory experiments 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.

      No, the phrase is:

    Seems to me that if diamond dust is that prevalent, then many spacecraft and satellites must experience a high rate of surface erosion. And in the long run lenses on satellites doing optical surveillance would get pitted. And solar panels get frosted. Does anyone know if this happens? And more important, on my next trip to Beta Gamma Orion IV, if the greys don't have shields, will the dome get scratched? And does my Galactic State Farm policy cover this?

    We have come a long way in synthetic diamond production. It would be way cheaper to refine that technology thanit would be to try scouring space for what is literally diamond dust.

  27. Diamonds Rare on Earth? by bbitmaster · · Score: 1

    Funny how The article starts out saying "Diamonds may be rare on Earth" We all know this is a lie that De Beers has propagated so they can charge outrageous prices. Diamonds are actually fairly common in certain places. Apparently they have the Jet Propulsion Laboratory fooled as well, because this article appears on their site.

    I'd say it definitely happens, and not just because of diamond dust--pretty much all the dust in space would do it. That said, "prevalent" is a relative term. Space is still pretty incomprehensibly empty, even in the really "dirty" parts. See http://www.space.com/scienceastronomy/dust_storm_030814.html where a "dust storm" is described as being the impact of 12 particles of dust per square meter per day.
