    Isn’t moon dust just sand?

      It’s sand that has never been exposed to water or oxygen. This leaves various reactive chemicals on the surface that would normally be broken down. The lack of water also means the particles haven’t been smoothed off as much. They are sharp and spiky.

      The combination of these effects makes the dust quite unique, compared to earth dust.

        It also reportedly smells like gunpowder.

          Burned or unburned? They are two distinct smells.

            Burned, according to the astronauts. I don’t know if the exact mechanism has been published anywhere, but since spent gunpowder has been oxidized I imagine that’s what’s going on with the dust as well.

        All those oxides but the iron is pure? SUS.

      Sand, but sharp due to a lack of water erosion, and formed mostly from asteroid impacts and thermal cycling. So it’s more like glass dust. It’s possible it has similar effects on lungs as asbestos, but we don’t know for sure.

Rules

  1. Don’t throw mud. Behave like an intellectual and remember the human.
  2. Keep it rooted (on topic).
  3. No spam.
  4. Infographics welcome, get schooled.


If you are here asking: “Is this a science meme?”

Probably, yes. We use the Dawkins definition of meme: a replicating idea, not just an image macro with a fact on it. A good post here doesn’t need to teach you something. It needs to make you ask something: who, what, where, when, and especially why or how.

Science isn’t a filing cabinet of facts, it’s a conversation. For example, a photo of an eel or other localized wildlife counts because most people never see one, and wonder is the first step of inquiry. A car meme counts if it makes you curious about what’s under the bonnet. If you want to talk about something you noticed in the world, chances are someone else wants to talk about it too.

We moderate for vibe, not category. Pruning is light, especially where a post creates interesting discussion. Experimenting is encouraged.

See the pinned paper on Shitposting as Public Pedagogy if you want the academic case for why this works.
