I’m pretty sure everyone is allergic to having their skin and lungs rubbed with mica.

Moon dust is functionally a lot like asbestos. It is composed of a sizeable amount of tiny shards of rock that aren't great for your lungs.

Yea, you should really consider that before breathing on the moon

xkforce@lemmy.world · 9 pts · 2y

Any lunar dust that they made contact with would have found its way into the lunar module for them to breathe in and be exposed to.

Isn't moon dust just sand?

cynar@lemmy.world · 86 pts · 2y (3 replies)

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.

Catoblepas@lemmy.blahaj.zone · 8 pts · 2y

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.

50% SiO2, 15% Al2O3, 10% CaO, 10% MgO, 5% TiO2 and 5-15% iron

And 100% reason to remember the name.

nxdefiant@startrek.website · 10 pts · 2y

All those oxides but the iron is pure? SUS.

More like Jack Schmidt = Cave Johnson

The sample size is at least a little bit bigger...

Some guy stole moon rocks (presumably still had moon dust on them) to bang his gf on them.

Roberts was sentenced to more than eight years in prison for his role in the Moonrock caper, as well as a separate offence of stealing dinosaur bones from a museum in Utah.

I'm afraid to ask what he did with the dinosaur bones!

credo@lemmy.world · 6 pts · 2y

Boned on bones, obviously.

Thank you so much

Raxiel@lemmy.world · 15 pts · 2y

So, if someone were to crash the moon into the earth to stop it escaping, as many as 1/12 of the population could experience a reduced quality of life?

Might need to consider not doing that I suppose.

He's a climate change denier though.

Not being allergic to finely graded rocks that have been bathing in radiation for billions of years seems more unlikely.

what'd be the smallest sample size that would yield a relevant result?

30? 1000?

Me. Just get me there
