NASA Needs Fake Moon Dust 179

Posted by Zonk from the like-to-see-the-requisition-form-for-that dept.
crisco writes "NASA's renewed interest in lunar exploration and 'in situ resource utilization,' or ISRU, is driving the need for tons of carefully faked lunar dust and sand for testing purposes: 'We don't have enough real moondust to go around,' says Larry Taylor, director of Planetary Geosciences Institute at the University of Tennessee in Knoxville. To run all the tests, "we need to make a well-qualified lunar simulant.' And not just a few bags will do. 'We need tons of it, mainly for working on technologies for diggers and wheels and machinery on the surface,' adds David S. McKay, chief scientist for astrobiology at the Johnson Space Center (JSC)."

    'This is very interesting. It is a very soft surface, but here and there where I plug with the contingency sample collector, I run into a very hard surface, but it appears to be very cohesive material of the same sort. I will try to get a rock in here.'

      As I understand the lunar dust is much "rougher" as it hasn't been polished by the same forces (eg: wind and water), which causes it to stick to just about everything.

      The Effects of Lunar Dust on EVA Systems During the Apollo Missions [nasa.gov]

      "the effects could be sorted into nine categories: vision obscuration, false instrument readings, dust coating and contamination, loss of traction, clogging of mechanisms, abrasion, thermal control problems, seal failures, and inhalation and irritation. Although simple dust mitigation measures were sufficient to mitigate some of the problems (i.e., loss of traction) it was found that these measures were ineffective to mitigate many of the more serious problems (i.e., clogging, abrasion, diminished heat rejection). The severity of the dust problems were consistently underestimated by ground tests, indicating a need to develop better simulation facilities and procedures."

      I wonder how someone could manufacture "fake moon dust" here on earth. Meh, at least I can sleep at night knowing this isn't my problem.

      • Manufacturing nano particle in mass has been going on for a few years now. Shouldn't be hard to use some of these processes to make moon dust. Sure it won't have the same randomness possibly, but it shouldn't be too hard, just an issue of scale. How much does NASA really want this, are they willing to buy enough to fund a factory.

I think a lot of the new simulants are necessary to test out industrial processes that might be used on the Moon and to better understand the likely effects of lunar dust abrasion.

      Because to simulate the "vision obscuration, false instrument readings, dust coating and contamination, loss of traction, clogging of mechanisms, abrasion, thermal control problems, seal failures, and inhalation and irritation" it certainly sounds like they could use asbestos dust and have something quite close.

      If the lunar surface is primarily aluminum oxide of some form (not that it is, but that sounds kind of right) then is will be both durable and abrasive. If testing is required to determine life expectancies of both operating equipment and excavation/drilling machinery then they will need to replicate both the particle size, distribution (in terms of seive percentages) and durability/hardness.

    It's quite abundant, and I'm sure there are some places in the Phillipines or maybe even our own Mt. St. Helens area where they've still got excess and would be happy to get rid of it. If that doesn't fit the bill, how hard is it to find rocks of the same composition as the moon, and grind them up?

    • I think the trick would probably be to get some volcanic stone, and then expose it to repeated explosions (not grinding) in an anaerobic environment, in as close to vacuum as you can generate on earth. By the way, grinding is definitely not the way to go here, as that would tend to polish the grains, making them far smoother than lunar dust.

      • Well, if the vacuum and lack of bacteria isn't important, then maybe they could give free stone targets to shooting ranges, with the stipulation that the dust be collected and given back. All kinds of problems with that too. Bullets are probably less energetic than meteors, and maybe you need meteors of various sizes. If it turns out they actually need to reproduce the process, that sounds like a really cool machine. You'd need to have one heck of a containment system for fragments produced by rocks col
