Isn't lunar dust an absolute nightmare made of sharp shards of material melted/compressed from large object impacts, or something of the sort? That has to be a nightmare on the skin or soft body tissues. And devices. The idea is fun, but I'm definitely not moving there. I mean uuuuh "it is my duty to let the younger generations populate the new frontiers while I hold the fort in their absence". Yeah, let's roll with that. Knowing my luck I'd be the first Selenite to die from lung lacerations infected from recycled air because the single live native bacterium of the moon decided to get cozy in my air filter, just the day the neighbor decided to clean the rugs. Or I'd get the only non-functioning internet connection in the planet. "Satellite's fried, kid, can't do nothin' until next rocket comes with da spare!". Jokes aside, is there some sort of good reference about the internals of the Moon? I never gave it a lot of thought but it makes sense it'd have some internal structure. While I don't think there's a lot of lunar spelunkers on the job, maybe we got something with scanning or something. I don't even know where to look.
