I half wrote a short story a few years back of a degenerate civilization of half a billion of p3rv3rted creatures living in lunar lava tubes that skipped colonizing the universe but settled on living in paradise-like greenhouse caves, their every whim realized by automated systems - so the big thing to do was just having s3x and partying non stop - and this became a tourist industry where visitors inhabited a sleeve body to spend some time with those lunies. Great place to unwind, de-stess - but you might lose a few points SAN. I postulated most communities were b1s3xual, others were strictly lez/bear/f3mboy/cis ... others were mixed futanar1 and a few ones near the polar regions were distinctly more wild. Think centaurs and hentaicles and goo-girls. One can hope I'll live to see this future.

I reckon any lava tube settlement would need to have certain safety features like we implement in big road & rail tunnels now. Namely side tunnels for utilities, evacuation, etc. Likely pressure and fire shelters too, plus said side tunnels would need to run along the main tube to serve as evacuation routes between damaged segments. As for the surface, here's hoping we'd be able to both have enough solar & thermal / chemical storage to get through the weeks of night. Though no doubt there'd be all manner of backup systems there too.

In the Expanse these Settlements have replaced Earth as the system's Breadbasket that is how much they could out produce anywhere else in the system for growing crops.

I think that one way to use lavatubes would be to use structural supports to it, and support inner walls from it, effectively leaving vacuum insulation in between like a thermos bottle. And maybe having some sort of plumbing to the rock and/or to the surface for managing heat inside the inner structure. This would alleviate most dust problems, as that could only enter through airlocks, and also fluctuations in temperature of surrounding rock material doesn't affect the living space practically at all. We don't yet know anyway how dangerous or toxic local stones, sands, and dusts, are everywhere on the Moon. What we know however, is that most of the stuff formed in anaerobic conditions near surface. We wouldn't like something like asbestos inside habitats, even if stuff is chemically inert...

You're definitely going to need a liner or at least some kind of spray on coating. It's going to be cold in a Lunar lava tube, well below zero Celsius. Once you heat it up and introduce humidity and oxygen there will be a constant rain of rock spalling off as it expands, hydrates, and oxidizes.

The temperature variation on a lava tube near the surface will be far greater NOW than it will be after we climate control the interior. Less than on the surface (+250F to -210F), but more than that of a habitat.

Will definitely need structural liners. The loads applied by even modest atmosphere pressures are simply immense !! And domes on the surface will need deep hold down piles.

FOUND THIS ONLINE "I would imagine that the main difficulty will be ataching some kind of 'bulk head' with an airlock system will be the most technically challanging part. The stresses at the transition of pressurized to vacuum will result in siginificant tension of the rock. This could result in fracturing. A rough idea of the amount of force acting on a bulkhead holding 10psi for a 30ft by 20ft lavatube (mathematically rectangular for simplicity): 30 ft*20 ft *144in2 /ft2*10psi = 864,000 lb The force concentrated around the perimeter of the bulkhead is approximately: 864,000 lb/(2*30ft +2*20ft) = 8640 lb/ft of perimeter. If the bulkhead sill is 2 inches thick this suggests a shear force per unit area of about: (8640 lb/ft * 1ft/12*in)/2 in = 360 psi. If the bulkhead were curved and set well into the bedrock, then perhaps a safe pressure tight bulkhead could wall off the open end of the lavatube on the moon. Interesting.'' People are thinking about it

I love this. Been waiting for this topic a long time.

I just want to say how much I genuinely appreciate this channel and all of the work that goes into it. I'm 36 and grew up watching the Discovery Channel when it was still worth watching.. SFIA has been in my top 5 youtube channels for years now and I hardly ever miss an episode. Thank you so much, and please never stop!!! lol Edit: There are so many unknowns that hide behind whether or not humans can have children in low gravity environments.

Make one more step and understand that we can explore the Cosmos only INSIDE the asteroids, if we curve out it's guts, build a decent living space and construct the engine, power enough -- to move a few millions ton mass in space. In complete safety!

As a gardener, I will add a bit of caution here. You say "a plant can undergo a period of low lighting" and then imply a cloudy week would be similar to lunar night. Now I am aware you know better, as even thick clouds let a lot more solar radiation through than the pitch black of lunar night. But for those viewers of you that were unaware: Two weeks of complete darkness are an extreme amount of stress for most plants we grow for food. Seedlings would be killed for certain, and larger plants suffer extensive damage, very likely more than 2 weeks of light can bring back in growth. All farming on the moon would rely on artificial light and (for lack of atmosphere, as plants can get sunburnt just as humans do) artificial shading as well. Maybe you could genetically engineer plants to survive it, and some lichen, moss etc might be hardy enough to survive, but default farming requires technical infrastructure for atmosphere, humidity, radiation management -> pretty much the same life support machinery humans also require.

I think lava tubes will also serve as emergency shelters or privately operated bases. The easiest way I can think to set up a base would be like those inflatable robots. A collapsed bag is stuck in the entrance, and as it inflates, it unrolls inside-out and fills the cavern. After that, you could stay there for a bit... or start pouring cement. Protection from radiation, micrometeors and the ability to better prevent lunar death-dust from getting any further inside by putting static filters along the entrance.

One of the problems of lava tubes on the moon is in sealing the tunnel to pressurize it. Putting aside the problem of fissures\cracks it boggled my mind trying to work out how to build a pair of walls to section off some. Natural holes may seem like a good idea until you recognize that that's where it already collapsed, so it probably a bad place to start construction of a massive crane system to lower all the gear and materials down. It might be easier to find an area of larger collapse where the sides are caved in, so you could construct a road. It might be easier to use seismic sensors and pound the ground looking for an entirely underground tube with no openings, and bore in to it. The hard part is making martial concrete. Maybe use mud ice for the outer layers?

In a mile wide lava tube that is on the Moon, ‘No wonder people think the Moon is hollow?’, so a hyper gravity habitat to grow children is posable and needed for colonies, ‘Adults would stay healthier in 1G, also.’

300 meters maybe, but rings don't need square sites. Once you get past gravity trains you might as well splurge and go with a multifloor parabolic high rise. If his estimate of the diameter of the largest lava tubes is correct, you could have a multifloor parabolic carousel completely inside a lava tube. For smaller lava tubes you could put the high rise in a cylinder over one of those "skylight" openings he mentioned.

Using the temp difference between the surface and below ground they could use memory metal to generate electricity. Someone would have to do the calculations of power to weight to see if it's comparable to solar power.

One interesting individual factor determining whether or not a family or person settles in a lava tube could be psychological trauma. For example if someone decided to leave earth fleeing warfare. If you experienced having to watch the skies for bombs coming in over your head, you might be more comfortable underground. This thought occurred to me a year or so back when I was trying to apply futurism concepts to the universe of Resident Evil via fanfiction. And I realized that even though the scenario I came up with ended with an O'neill cylinder's worth of space on an ark ship, and a few tens of thousands of humans remaining split between being awake and cryo, (with the possibility of using cloning and mind uploading to revive even more than that), that the survivors in that scenario had just seen an end of civilization scenario that involved missiles containing bioweapons and nukes alike, as well as AI driven drones from the WBE of a madman attacking them with both bombs and nanites. (The madman was Albert Wesker, if you're familiar with that universe's lore.) And they may not want that giant cylinder to live in if they had a choice, or open sky over them, and may well give it over to the few animal species they managed to save and take with them or the surviving J'avo (a species of mutant from RE6 that really do need a lot of room compared to normal humans, see google). Even though they'd gotten safe breathing room, the people in that scenario I'd come up with just didn't feel safe in a wide open space. They wanted more rock armor melted onto the outside of their ship to carve apartments out of instead, because many of them just couldn't sleep well with open or seemingly open skies. It makes me wonder what kinds of cultures those early settlers might come from or create. If you lived through war with a lot of bombs being dropped on your head, why would you want to even think about living in a dome that could become a target? You might just put your cropland and animals in the dome and come topside for some sunlight during the lunar day, then drive your animals underground into a shelter when you go to sleep so that if you're attacked while sleeping you don't lose a good chunk of your food supply. BTW, I wholeheartedly endorse mushroom farming on the moon. Just please give me enough heat and humidity to raise pink oysters. I love them so much they're my youtube avatar pic!!! 😆 🍄🍄🍄🍄🍄🍄🍄🍄🍄

I think it would depend if you were a long term resident or a transient technician working on something for a few weeks or months. Humans are ver adaptable creatures. Personally, I would love to get away from most of the people who now have their heads buried in cell phones. I know quite a bit about algae and aquaculture and would really enjoy raising fish on the moon both for ornamental purposes and food.

I imagine living in long Lava Tube settlements with artificial gravity mats in the initial phase of my colonization of Proxima Centauri b. Proxima Centauri may be my Pearl Harbor to Earth’s Imperial Japan.

What do you mean by Pearl Harbor. Will Earth attack?

@ebonaparte3853 Proxima Centauri is home to a Fleet Shipyard and Intermediate Maintenance Facility of Imperium. Earth better not attack. Honestly, I think at that point Earth will have become a polluted and decayed planet consisting of billions of bilious retardāres, almost insect-like in their mindless conformity, existing in the very conditions of squalor and poverty which exist today in countries such as India, Burundi, or Haiti. If somehow, miraculously, they field an attack. The Imperium will TAKE OUR MOTHER PLANET BACK and do so in a way that will make Genghis Khan look like a pacifist girl scout!!!

"Are they places someone would want to live and raise a family?" No, as even if we make the assumption conception is possible, it would be a death sentence for the parents and doom the children to be stuck on the moon as they could not survive leaving on anything other then an orbital elevator and could never go to Earth or any cylinders.

I think that living on the moon is perfectly reasonable for survuval purposes... the 2 planet species concept. Apart from that it would be a good place to build bigger rockets.

Issac is so smart, next to him I feel about as smart as a potato.

also you were in Pittsburgh? i missed it, its so cool that astrobotics is in my hometown ,🥰
