Being only light seconds away is huge. Also, establishing a base on the moon makes it possible to get help and supplies to mars much easier to respond to than trying to launch from earth. Also, before anyone arrives at Mars, we can turn the landing pad on Mars into an IKEA waiting for the astronauts to show up with the screw driver and hammer. On the moon we can also grow food in the lava tubes and light them with artificial lighting, raise chickens and turkeys and with that much water, we could pond raise fish and crustaceans, as well as grains and cereals. Any pound of food you raise on the Moon is a major savings. We must remember that the surface of the moon is a shooting gallery and the risk of solar flair radiation is ever present. This is why we have to live and farm under the surface. The dust on the moon is an interesting threat and blessing. The dust gets everywhere and ruins couplings and pivots, but I understand that if you hit the dust with microwaves you can get the dust to anneal to form a crust. It may be a quick way to make paved roads and maybe glass bricks. Or just a way to keep the dust at bay around the base. There is no atmosphere, but there are multiple impacts a day from meteors coming in at ballistic speeds that will throw up the dust to settle everywhere.

Industrializing the moon is our best bet. The earth wouldn't get polluted nearly as much and all of the toxic waste is left on the moon. Also, all of the CO2 emissions emitted by factories on the moon would help to create an atmosphere that we could use as leverage in terraforming it to become habitable.

Gravity on the Moon is pretty low for retaining an atmosphere, but putting a robotic/telepresence factory complex on the Moon would allow us to mine it and build space infrastructure and materials without having to boost the materials out of Earth's gravity well. Cool.

[@freespirit9981]

Other countries wanted to be the first on the moon so that pushed USA. Now China wants to have the first base on the moon. Their is one issue there think China does not see. Russia and USA see it you can easily just put a base on the moon but does it pay for itself or is it just going to be more wasted tax dollars? So getting a base there without having sustained income now you have a base that will fall into disrepair when the first major economy krysis hits. USA was smart by getting companies involved to think and develop the other infrastructures processes that will be needed if you want the base to pay for itself. Plus think things have been on hold till they develop a fusion reaction that can be contained. What is the point of getting H3 for electricity if you can not use it yet? One element that will be a vital key to moon base profitability. As other minerals costs more and more to mine we will eventually meet a threshold where it will be cheaper to go to the moon and mine and then send the material back to earth. While at the same time saving our limited supply of clean drinking water that we have on this planet. But their is one factor all countries should be looking at right now is the cost of green house gases versus human health. If we can do more of this stuff on the moon limiting the CO2 emissions then that could have a mass savings when it comes to human health or even all life health for that matter.

In case of interplanetary trips, I found that only rendezvous of a tanker and a ship on highly elliptical orbit make any sense, but it also took a lot of time. Delivering the fuel by a single stage vehicle to the most desired LKO is very inefficient even using aero breaking - rather a not desirable maneuver in the real word. I used only chemical rockets to simulate the current technology status. Nuclear engine also didn't change a lot the situation, the number of deliveries to return the investment was crazy high.

Well, Its not a small endeavour, but its a nessesary steping stone for the simple fact that the mood is by far the best refueling station and spacecraft manufacturing site in our area. You have ICE to make fuel, low gravity to build massive constructs, no atmosphere to hamper you in sending things in orbit, and rare materials that are nessesary for any high tech construct. Yes, we CAN colonize mars without the moon, but the simple fact that the moon is the perfect spot to refuel a starship, or build killometer long solar reflectors to power up the earth/other planets or even begin the terraforming process of mars (using the reflectors to help heat up the surface, and power up the gigantic magnetic field generators needed to shield mars from the solar wind), it makes the moon a crucial asset to have on hand during ANY expansion and exploitation plan.

When you brought up the concept of disassembling the moon to provide resources for a orbiting colony, in got me thinking. Using the entire moon would be of course, devastating to the earth, causing catastrophic geological upheaval. Even scaling back this idea, we are looking at using vast quantities of lunar resources to bring to earth and also to colonize the rest of the solar system. At what point does the removal of mass from the moon begin to affect the earth in any measurable way? Small but measurable changes to tidal forces, as an example. I know this might be seen as an infinitesimal issue and might take generations to cause any effect at all but it seems like it would be a fairly simple (for a mathematician, not me) calculation to perform and at least give us a clue about our impact. There was a point when previous generations (and even some still today) could not fathom humans having impact on earth's climate. I am not a tree hugger either, but I think our impact on other planets or moons is an ethics discussion that at some point will need to be addressed.

First of all, I wanna thank Issac Author for making this video in English caption. It benefit me greatly. Why? Cuz I’m deaf. Reading captioned videos is really educational. Just like listening the narrator speaking about their topic in every videos in KZbin. Now...about Mining the Moon... I’m all for colonization to the Milky Way Solar System but im not too sure about mining our Moon 🌙. Why? If we mine on the Moon for our daily needs, then by theory, the Moon WILL become smaller & smaller. I don’t know if you have heard somewhere on what caused the wind 🌬 that we feel everyday? To my surprise, the pull of the Moon’s gravity toward the Earth 🌍 are what caused the wind that we feel. So if the Moon is gonna get mined for the Moon’s colony, will we no longer feel the wind? My theory suggestion is to recycle what the Moon needs and what we need. Feel free to debate. No need to bash people with mean words. Just wanted to hear your thoughts on mining on the Moon. Thank you.

[@levizion6167]

I love these videos. We live in such a vast universe, it would be nice to explore even a small part of it. I am hoping that colonizing the moon and mars will lead to cheaper and faster methods of traveling through space. Plus I like the idea of terraforming other worlds.

[@valrond]

One of my favourite episodes, and that's saying something, cause I like this Upwards bound series a lot. And this is something that we might actually see in our lifetime. The start of a colony on the Moon.

[@unvergebeneid]

Pretty sure the Moon is a much better choice for a permanent colony than Mars. A Moon colony seems economically viable while I don't see that for Mars. People often forget that humans don't go to live somewhere because they can but because there's something in it for them.

[@Molb0rg]

Mars and any other body in solar system can be economically viable, not the point of the video. Ruch to mars, just cuz we can - yep, a bit questionable "plan", however, it does not mean it should fail.

[@unvergebeneid]

Not even Antarctica is economically viable. We only have a base there for science. A body that is more expensive to live on and _much_ more expensive to get to and from? I don't see it. What's their product? What's their USP? What's so much cheaper to make or dig up on Mars that it's worth the cost? I think you might be confusing the possibility to be self-sustaining with the ability to be economically viable. Remember all those cultures that were self-sustaining before the Europeans came and made them poor? Sure, they were exploited and everything but they were also suddenly exposed to a global marketplace. If you can't keep up, that makes you poor. Or in other words, not economically viable. Mars would be poor. Until the Earth explodes, any ability to be self-sustaining doesn't help Mars one bit to avoid that fate. The only thing that might save them is that they might be _so_ hard to get to, that they are basically isolated. Then they can do their own thing and technologically fall behind Earth in relative peace.

[@bozo5632]

+Penny Lane - the top few meters of lunar soil alone is worth more than all previous human economic activity combined. It's actually worth more than the whole Earth, in terms of raw materials, since more of it is more accessible. (It's geologically mostly dead and cold, most of Earth is too hot to dig in.) Once the infrastructure is built, manufacturing and agriculture in space will be much, much, much cheaper, safer, greener and more sustainable than doing it on Earth.

[@badbeardbill9956]

And free space is a much better choice than the Moon. Look up space settlements. O'neill cylinders.

[@unvergebeneid]

I really don't think it is at the moment. You've got to transport everything up there, you've got to build every square meter of real estate, you've got no free rock you can use for radiation shielding and most importantly, you've got no natural resources. I'd say you _need_ a Moon base before you can even think about building rotating habitats. You don't want to hurl all the building materials up there from Earth.

I suppose that would be one way to assure the sun would never set on the British space empire. I do also wonder at what lower level of Earth orbital satellite construction it makes sense to start mining on the moon, somewhere before or around orbital rings or space elevators perhaps but i guess there are too many cost factors with too little information.

Personally I think the moon would be a learning and development curve for us before going to Mars. Perfect tech on the moon the use it in on Mars tried and tested. Plus the moon then is usable as the space gateway instead of building one in orbit of the earth. It would have most of what we need to build with and it has a lot less gravity than earth so obviously would need a lot less fuel than an earth launch. It's a sensible direction why waist money on something that would be made obsolete by technology over the decades after its completion. The moon base would be upgradable and large enough to make great real estate for industrial/colonisation which would relieve the earth of overpopulation. From there to Mars then we have a true multi planetary race which is virtually impossible to wipe out even by natures standards. Great vids Isaac really enjoy your work thanks

[@maxnaz47]

Success! I no longer require closed captions. :-D

[@maxnaz47]

Just a thought, i don't know if you read these comments or not, but i am curious, the general assumption is that all the matter colliding with earth, the moon and other celestial bodies is that the mass is added to it. However, we know that even here on earth, we are losing mass faster than what we are gaining it. Thinking about an impact on the moon, the amount of material ejected by the impact would be far greater than the mass of the meteorite. Given enough time, the reduced mass of both earth and the moon perhaps is the cause of the gravity between us becoming weaker and the moon drifting further away, so potentially, if we could in fact, add more mass to the moon, perhaps we could slow its rate of escape and create more 'balanced' seasons? Perhaps building a moon base and using the mining profits to send back to earth and once a mining colony is set up and functioning, start looking at bringing in asteroids to land on the moon that we can mine. If we are looking for specific minerals or whatever, we can select the appropriate asteroid to bring in, it may take years, if not decades, but having the moon as launch platform the the rest of the solar system should reduce costs substantially. What do you think?

[@deus_ex_machina_]

@@maxnaz47 Neat idea. Never thought of that.

[@bozo5632]

+pumpuppthevolume - fuel is no problem. There's some water on the moon, and water is unrefined, high grade rocket fuel. Plenty of air, water and rocket fuel up there, trapped in the surface gravel and especially in polar craters.

You won't need much fuel. A space elevator on the Moon is much easier than on Earth. Even if you used rockets, you could also use skyhooks.

Must admit this is a very interesting and thought provoking video for space travel, long time living, terraforming and mining mineral/precious metals on both inner and outer planets or moons/asteroids.

Moon has 1/6 gravity. If that's good for manufacturing, then orbital factories where you can have any gravity you want, are even better. In one rotating station, you can have a zero G stockpile in the hub, a micro-G area for heavy transport, low-G factories, one-G crew sections, and even arbitrarily high-G areas if you wanted. Even better. We don't need no stinking planets. (Or silly moons.) Space is the place.

[@squirlmy]

But the moon has raw material, and unmatched orbital stability. And heaven help us if we get space espionage or even warfare, whether between space-faring nation-states or corporations, etc. Orbital factories would have little defense and need to be hardened against lots of threats. A factory in a moon crater or tunnel would be much better sheltered. Piracy developed right along European exploration overseas, I imagine the same might happen in space.

[@badbeardbill9956]

OP: Yeah. Planets and Moons aren't all that good for habitation. They're great for resource extraction, of course. And they'll be fairly well defended, if need be. Remember, they have to protect against potentially large asteroids. Gonna need some beefy lasers.

[@bozo5632]

+Cuvtixo D - A lunar bunker might be tough enough to survive an attack, but it would have to be a real military bunker, not just a surface base. Otherwise it's probably about the same, except the moon is a more predictable target. Probably you live in Cleveland or some place that's surely more vulnerable than an orbital station would be. Whoever controls space can destroy any settlement anywhere anyway, on or in the Earth or wherever, so I don't see it as an additional problem.

[@bozo5632]

+Cuvtixo D - orbital stability is good, but active station keeping and/or interplanetary propulsion is even better.

[@andrewgoodall2183]

Much as I enjoy Isaac Arthur videos, and I do appreciate they deal with higher concepts rather than achievable shorter term realities, whenever he's discussing the more obtainable things like on this video, I spend my whole time thinking "supply chain". Even with a decent sized moon installation, you still can't just fabricate and build everything on the moon just like that. The sheer amount of production plant for all the things you'd need for even what we'd consider mundane technology would run into the hundreds of thousands of tonnes and such diverse material requirements it's crazy. You can't just say "3D printing" and all of that goes away. Smelting iron on the moon (though still very difficult) or making the lunar equivalent of a concrete block, or making fuel - yes, only a few tens of billions of dollars and a few hundred tonnes of plant required to make that happen. Making a component that requires a hundred different sub-components and THEIR sub-components using a total of hundreds of different materials all created using thousands of different processes, with each and every process, however simple, potentially requiring tonnes of unique production plant, means you are needing a city sized installation before you can even make a clock radio, let alone a spaceship. Globalisation alone makes our technological lifestyles possible, and a production-level moon base still requires all that globalisation, with the moon's link to it being by way of a prohibitively expensive Saturn V equivalent. This is why we don't live on the Moon, simple as that.

[@davidtekaat246]

I have looked at a lot of videos about colonizing the moon. And I haven't found any with my same ideas. I think we should set up a moon colony on earth. We should have inflatable domes, which we cover with 3D printers with simulated moon mortar. The domes should be connected to each other by inflatable tunnels covered with simulated moon mortar. There should be living quarters, hydroponic green houses, gardens with garden soil for recreational gardening, a 5 acre pasture with one inch of garden soil and one inch of grass turf, a park with artificial turf and with small sections of real grass turf, and maybe even a very small zoo. All the domes will have plastic floors so no water is lost. Condensation forming on the ceilings will be drained into the water supply. All the domes will be blown up with compressed air from earth and will have a refresh system, which will refresh the air and maintain the air pressure. Humidity, Temperature will be maintained by humidifiers, heaters, fans and coolers. Light will be provided by multi-color LEDs, mostly white. Power will be supplied at first by solar power, and later by nuclear or fusion power. There will be a bull, a cow, two sheep, and two goats, two chickens, two turkeys, two fish, and two rabbits. There will also be pets, two dogs, two cats, two bunnies, etc. (and maybe a small zoo) All of this will be set up by astronauts and robots before the colonist arrive. The first colonist will be 5 fathers and 5 mothers, and 90 babies. The parents will be good parents, gardeners, farmers, zoo keepers, teachers, etc.. During the first two years an exact duplicate facility will be built on the moon. When the babies are two years old, they will move to the moon and live on the moon. Or if it is proven that they will be too young to travel to the moon than the facility on earth will be added to, to accommodate 10 more parents and 90 more babies. The two year olds would move into the new addition. Every two years the facility will be either added to, or 100 people will move to the moon. This plan will allow the kids to grow up in the isolation of the colony, and will make it easier for them to live in the isolation of the colony on the moon. And will allow them to grow up on the moon and be better able to adjust to the lower gravity on the moon, although some artificial gravity maybe eventually provided. This artificial gravity will especially be good for the parents. The kids will have everything in the facility to keep them occupied and entertained. Also they could have some books, movies, games, etc., especially adapted for them, being careful not give them anything that would make them feel isolated. After 20 years there could be 2000 people living on the moon, most of whom grew up on the moon. This program could be speeded up so in 20 years there could be 4000, 6000, or 8000 people living on the moon. This program could be simultaneously done to colonize Mars so we could have 2000 people on the Moon and Mars at the same time. For the moon we could send supplies every month, but for Mars we could only send supplies every 26 months. So I suggest we send 10, 20, or 30 rockets to Mars every 26 months all at the same time. We could have several refueling stations along the way to mars and orbiting mars so rockets could refuel along the way to mars and right before landing on mars so the empty rocket would have enough fuel to take off again, refuel in space and return to Earth. Eventually the moon and Mars could export minerals or small expensive items that were assembled on the moon or Mars, like jewelry, iphones, iwatches, etc. Or grown on the moon like caviar, marijuana, etc.

It occupies an unlikely orbit and is so extraordinary that all existing explanations for its presence are fraught with difficulties are none of them could be considered remotely watertight.”"
