Moon cave discovered that could one day house humans
Moon cave discovered that could one day house humans
It is the first cave to be discovered on the Moon and could protect astronauts from radiation.
Scientists have for the first time discovered a cave on the Moon.
At least 100m deep, it could be an ideal place for humans to build a permanent base, they say.
It is just one in probably hundreds of caves hidden in an “underground, undiscovered world”, according to the researchers.
Countries are racing to establish a permanent human presence on the Moon, but they will need to protect astronauts from radiation, extreme temperatures, and space weather.
Helen Sharman, the first British astronaut to travel to space, told BBC News that the newly-discovered cave looked like a good place for a base, and suggested humans could potentially be living in lunar pits in 20-30 years.
Oh you... 🤣
You fucking asshole. How fucking dare you sully the moon like that. Piece of shit. upvotes

Oh God! It's mooning us!

Fuck. No, please. Just no.
The shadow acts as the wedding band. Accepted.
Next-level mooning.
Just wondering what it means for history if the first humans to start living on the Moon do so in a cave.
Maybe space cavemen?
We're cavemen on the Moon, we carry bone harpoons! But there ain't no whales so we tell caveman tales and sing a whaling tune!
Because it's costly to bring materials and to set up mining operations, a lot of tools will be made of readily available moon rock. So, maybe we'll have a moon stone age, too.
More, shelter.
There's no atmosphere to attenuate hard radiation, so rock overhead is the next best thing.
There's no gravity to contain an atmosphere, and domes are expensive and time consuming to build. Meanwhile the crews are exposed to radiation.
There's nothing but regolith on the surface of the moon-- finely powdered rock of unknown (and likely poor) assay for vital ores and minerals useful to bootstrap a colony.
A cave provides shelter, more assay-ably dense ore resources, potentially water in the form of subsurface ice, and potentially a vitrable (melted, glassified rock) cavity to contain a viable, pressurized atmosphere on the quick.
A cave on the moon is a find. Given the potential for neocolonialism in the next decade or three, it's a boon for whatever program discovers one.

Eh. How hard is it to bring a little arc furnace and start making aluminum? Hell, magnesium would be even easier, since hard vacuum is cheap up there.

Yet...
Mildly related by the topic. I'm playing ghost recon breakpoint and a bunch of the main characters are hiding in a huge cave. My character said something like "do you have a computer?" And the NPC replied, "I live in a cave, I'm not a cave man" .
I... expected this
Glad to live up to the expectation!
This is the best summary I could come up with:
Scientists have for the first time discovered a cave on the Moon.At least 100m deep, it could be an ideal place for humans to build a permanent base, they say.It is just one in probably hundreds of caves hidden in an “underground, undiscovered world”, according to the researchers.Countries are racing to establish a permanent human presence on the Moon, but they will need to protect astronauts from radiation, extreme temperatures, and space weather.Helen Sharman, the first British astronaut to travel to space, told BBC News that the newly-discovered cave looked like a good place for a base, and suggested humans could potentially be living in lunar pits in 20-30 years.But, she said, this cave is so deep that astronauts might need to abseil in and use “jet packs or a lift” to get out.Lorenzo Bruzzone and Leonardo Carrer at the University of Trento in Italy found the cave by using radar to penetrate the opening of a pit on a rocky plain called the Mare Tranquillitatis.It is visible to the naked eye from Earth, and is also where Apollo 11 landed in 1969.The cave has a skylight on the Moon’s surface, leading down to vertical and overhanging walls, and a sloping floor that might extend further underground.It was made millions or billions of years ago when lava flowed on the Moon, creating a tunnel through the rock.The closest equivalent on Earth would be the volcanic caves in Lanzarote, Spain, Prof Carrer explains, adding that the researchers visited those caves as part of their work.
When you make these discoveries and you look at these images, you realise you’re the first person in the history of humanity to see it,” Prof Carrer said.Once Prof Bruzzone and Prof Carrer understood how big the cave was, they realised it could be a good spot for a lunar base.
“After all, life on Earth began in caves, so it makes sense that humans could live inside them on the Moon,” says Prof Carrer.The cave has yet to be fully explored, but the researchers hope that ground-penetrating radar, cameras or even robots could be used to map it.Scientists first realised there were probably caves on the Moon around 50 years ago.
Then in 2010 a camera on a mission called the Lunar Reconnaissance Orbiter took pictures of pits that scientists thought could be cave entrances.But researchers did not know how deep the caves might be, or if they would have collapsed.Prof Bruzzone and Prof Carrer’s work has now answered that question, although there is much more to be done to understand the full scale of the cave.“We have very good images of the surface - up to 25cm of resolution - we can see the Apollo landing sites - but we know nothing about what lies below the surface.
There are huge opportunities for discovery,” Francesco Sauro, Coordinator of the Topical Team Planetary Caves of the European Space Agency, told BBC News.The research may also help us explore caves on Mars in the future, he says.
That could open the door to finding evidence of life on Mars, because if it did exist, it would almost certainly have been inside caves protected from the elements on the planet’s surface.The Moon cave might be useful to humans, but the scientists also stress that it could help answer fundamental questions about the history of the Moon, and even our solar system.The rocks inside the cave will not be as damaged or eroded by space weather, so they can provide an extensive geological record going back billions of years.The research is published in the scientific journal Nature Astronomy.Graphic by Gerry Fletcher

Citation please?
Oh boy, finally! For decades, the lack of caves has kept us from living on the moon. No more! We will take those caves. And then we will live the shit out of the moon! Moon cave, baby!
but they will need to protect aronauts from radiation, extreme temperatures, and space weather.
Space weather? Like meator showers?
Yes i believe it has to do with the moons atmosphere or lack there of one. Space rocks won't burn up like they do on earth and therfore are more likely to strike down.
Since the solar wind would probably be covered by "radiation", yes.
At least 100m deep, it could be an ideal place…
Seems excessively very deep to me - someone’s going to have to build a freight elevator as tall as a soccer field is long. Even worse, I’d expect you’d want your airlock on the surface so you’re not struggling to maneuver in a bulky suit just to get outside: now you’re talking about a 100m pressurized elevator.
Does anyone know how deep you’d ideally want? I’m sure NASA has studied it. I do remember reading that 1’ is the exact wrong number because of indirect radiation. While you get more protection from radiation and a more stable temp, the deeper you go, the marginal value probably drops off pretty quickly, plus the inconvenience would quickly climb. When people online talked about living underground on the moon, I always imagined like 5-10m
Edit: here’s an argument to keep it less than 12m deep
Edit2: and here’s an argument for at least 1-2m
I would design the elevator car to be self-contained, rather than pressurizing the entire shaft.
Actually, it would be more like riding in a pressurized moon rover. Then, using wheels or rollers on opposing sides of a track to act as guides, some kind of hoist, or maybe just a linear inductive motor using the track as a stator plate.
The advantage to the linear induction motor is simplicity- if you’re building the track/guides out of metal any way, then, it’s just a few more components and you have a way to go up, go down, and brake.
In any case there’s really no reason to have a pressurized shaft.
The value of the cave is it’s already there, with no need to excavate that incredibly annoying moon dust. Which, to be clear, is a horribly hazardous material.
Because there’s little to no natural erosion, it’s sharp and splintery and highly barbed. It’s also magnetic, so it sticks to anything made of iron or steel; and for example probably causes something akin to silicosis.
It’s basically the reason that NASA and others are looking at pressurized rovers with suit ports for hopping out instead of an airlock and space suit design. It significantly resizes the amount of moon dust coming in.
Remember, there's not a lot of gravity on the moon, the energy to get in and out of that hole isn't the same as on Earth. You could probably create a tether that could be ridden up and down.
See the link on my first edit. Even in the Moon’s low gravity, a fall over 12m is potentially fatal. It would be foolish to live such that astronauts take this extra risk every day.
You also have to get all your stuff down there in one piece. Sure, more ropes, but tons of equipment, huge sections of living quarters and airlock, construction vehicles, etc. then every supply run needs to get tons of supplies all the way down there. You could do it, but it seems like giving yourself a lot of unnecessary work, taking up way too much time. And of course any sort of cave-in makes any survivors completely unreachable
but first you have to kill the bubbul frog
That's no moon.
Hooray, we solved the homeless crisis.
