@@cheynestahlhut2061 That would make a lot of sense. A fully rigged model of the equipment plus a photogrammetry setup to model the immediate environment at regular intervals. It wouldn't be very difficult. You'd control a simulation in real time and take frequent 3 second breaks to wait for the live cam to catch up so you can verify that nothing unexpected happened. For any particularly tricky maneuvers, you could pause sending command instructions to the moon until you did it just right. Essentially, it's a custom save point. You'd just resume transmission once you've done it perfectly and wait out the delay to see if it worked.

Moon dust is a major health issue, I wonder how living on something akin to asbestos will affect the design process.

[@mjk9388]

Andrew Michler I agree. I have often wondered if that’s one of the reasons (along with radiation) that Elon Musk has wanted to pursue Neuralink. Im guessing with Neuralink a human might be able to control robots outside the habitats with just their thought. A robot could then do all the work so that you don’t have those dangers with humans being outside the habitat. At the same time, the AI that will eventually be part of Neuralink would then be learning how to control those robots by itself without a human’s conscious thought. Maybe I’m overthinking that a little, but it would be a novel approach to minimizing the danger to humans while quickly teaching AI how to control the robots.

[@steffenjespersen247]

It is not a super big deal if you design around it. As there is no atmosphere it only moves if something kicks it up and even if that happens it will just fall straight down again. If you are only running robots you can just enclose the buildings that needs to be clean and have those robots stay inside not walking in and out dragging dust. If you wish to keep your solar-cells clean then just dont drive of fly near them, just lay a long cable.

Environmentalists don't love plants and animals, they hate humans. Well, most of them. If they talk about terrestrial solar or wind power they hate humans. If they talk up the French power grid or regulating the climate with giant space mirrors or massive arcologies they love plants and animals. If they talk about beamed orbital power it's hard to tell, that group might just want orbital death rays.

[@tokilladaemon]

“If environmentalists believe in wind and solar they hate humans” Jeez dude it’s only January and you already dropped the shittiest take of the year

[@nicholashollis1522]

@@tokilladaemon Wind power is rather inefficient and wasteful, not to mention an eyesore that kills birds. Also, oil and other fossil fuels provide the vast majority of the earth's current power, not even including vehicles. You cannot propose reduction of fossil fuel usage without massive changes in society that have us abandon luxuries or conveniences, economic growth, and having us make immense investments at an opportunity cost. However, Nathan Brown is *woefully* wrong in dismissing solar power. Solar, hydro electric, and geothermal energy are the MOST promising energy sources available today. Solar is such a solid investment that homeowners will put panels on their roofs and sell excess power back to the grid. I predict solar and nuclear energy will be the primary energy sources in the coming decades, especially as we find better uses for recycling spent nuclear fuel. Something rarely discussed in these sort of energy discussions is there's currently no green alternative for air travel, we cannot simply ignore this, nor can we maintain modern society without air travel.

[@nathanbrown8680]

@skem Simple. Wind and Solar are environmentally destructive and are incapable of meeting the needs of the current human population. Wind turbines are devastating to wild bird populations and require extensive networks of roads for maintenance. Solar is land inefficient requiring massive habitat destruction. Both require either enormous quantities of batteries for continuous power and producing those batteries and disposing of them at the end of their useful life entails massive chemical pollution. By talking about "renewables" instead of "carbon neutral" the greens make the only way to balance the energy budget to reduce humanity to a pre-industrial lifestyle that cannot sustain anything approaching the current population. Thus people who care about both the environment and people either push nuclear power as the only available and viable non-carbon producing power source that scales beyond the limited number of hydroelectric suitable rivers, propose climate change abatement methods that don't care about carbon, or don't believe in anthropogenic climate change in the first place and thus don't consider carbon dioxide a pollutant. Since we have solutions established to all the other pollutants associated with fossil fuels they're not talking about power generation at all except to oppose wind, terrestrial solar, and new hydroelectric plants on habitat destruction or endangered bird killing grounds.

To be fair, we get a healthy dose of this already. Any long term viewer knows Isaac's view of how probable an interstellar war where the outcome is uncertain is.

You should do more episodes like this these are the things that people are looking to your channel towards more close time less long time

[@UtraVioletDreams]

Isaac you're channel contains a lot of speculation. But! It's always very well thought through. And out of tons and tons of other channel's, it's really one of a kind! Edit: I'm getting fat from all those snacks :D

[@fabianherrmann6398]

Same. Forget the moon. When is science helping me to overeat and still stay slim?

[@sparcer1]

Issac you are way better than first I started watching, bravo Love your vids

[@tedbreuer6927]

Try "The Expanse" series; more plausible than Star Trek/Wars... You'll enjoy all the detail of what can be possible.

[@John_McJohnson]

If you can get past the absurd idea of the UN controlling anything.

[@palfers1]

Bravo Isaac. Many useful topics covered here today.

[@brianofphobos8862]

Arthur, check out how much Earth light hits the moon. I believe you will be supersized.

[@timesathousand]

I love how Isaac talks about the grand strategy of what projects are worth investing: moonbase vs bypass the moon vs O'Neil cylinders etc. One day I really hope our species--or at least enough of our species--are united in efforts to undertake projects like this and are investing our resources towards the most optimal payout for humanity as a whole rather than for shareholders. Isaac is one of the only things in my adult life that actually makes me hopeful that Star Fleet could one day be a real thing. Thanks dude.

For now, colonizing the Moon makes MUCH more sense than colonizing Mars. Elon Musk is jumping the gun a bit. We need some serious space infrastructure in our local cis-lunar neighborhood first.

[@killroywashere1254]

Graveheart We were told by the Aliens (the Moon is ours) get off and stay off. That is why we haven't been back to the MOON!! Elon Musk knows we have been told!!! We will have to bargain with the Aliens to build a colony on the Moon. and that won't be easy.

[@Starbat88]

@@killroywashere1254 I suppose that makes sense. If some other alien civilization colonizes the moon first, do we really have the right to tell them to leave, just because the moon is in our orbit? Especially if they have been living there for generations...

[@lghammer778]

Great episode, Isaac, cheers! 😃🙏🏽🖖🏽

[@biglenin7306]

Why is eleon musk so focused on Mars??? He needs to foucus on the moon!!!

[@jwadaow]

He is designing a vehicle capable of either.

[@sweetwater4583]

Playing on the decades of science fiction authors writing about mars for cash?

[@animistchannel2983]

SpaceX ships won't need the moon. They are already designed to lift what they need direct from earth to orbit, and operate directly from earth orbit to mars and back. The moon is an industrial staging area for earth-orbit-area operations, but mars is a much larger (and terraformable if you want) staging area to the entire rest of the solar system. SpaceX is going directly to the long game, because they can, while others are still basically screwing around in earth's gravity well. Both the moon and mars can be used to build O'Neill Cylinder-type habitat ships, which is the true future of space development and settlement. Once you have those, all limits are off and you can go anywhere for whatever reason you want. They go up... and they don't have to come back down. That's the mother ship from which you control your moon or mars or asteroid industrial sites, while the workers live in regular gravity, with fresh grown food, normal family lives, and just have to take workday shifts in the various weird conditions. Moon-built ships will be more likely to hang around and have service relations with the earth area. Mars-built ships will tend to expand outward into the gas giant systems and Kuiper Belt zones. There is plenty of use, and room, for many kinds and missions, and enough space companies to do them all.

[@fabianherrmann6398]

It is telling that NASA and SpaceX is aiming for Mars and ESA is focusing on a moon base concept to test equipment there and use it as a launch pad. I think it is the American fixation with being first somewhere new, which is a great motivator and fine by me. ESA has not that much money to burn through and thus rather keeps it closer to home.

[@animistchannel2983]

@ I think at some point people just have to take Elon at his word, that he's doing mars to make humanity a multi-planet species, that makes earth-based life cosmically harder to wipe out, and leads to a future that gives him hope, where we expand across space. That's a non-business, idealistic, star-trekkie geeky goal. If you remember his actual speech introducing the BFR/Starship, he said, "...but we have to find a way to pay for it." Since then they've made more products, more profitable support companies (like Boring & Solar), and launched StarLink. That's the earth-money they need to pay for establishing mars until it's self-sufficient.

[@skipkurtz2705]

Professor Arthur, you make complex issues such as these understandable to uneducated admirers of space, like me. Thank you so much. I'd rather watch your videos than science fiction, and has been my favorite genre for fifty years!

[@TheGrinningViking]

I figured out the moon braking problem, right now! Sand bags, sand bags filled with moon dust, it would be rediculously cheap and simple. Toss in a net at the end and sides to catch the bags and they will fall back into place. It'd also provide error correction for overly fast landings - though you would want not to hit the net, as it would then likely need some simple repairs.

[@chrisbrandenburg3505]

I'm laying in bed watching your videos and I just had a horrible thought. Can you imagine the moment that we've discovered every species of life on Earth. Nothing more to explore. The excitement of discovering a new species gone forever I don't know why but that scares the crap out of me

[@joeredfield979]

That magnet rail gun ship launcher is an amazing idea to imagine.

[@guilhermecunha3363]

Also, I started reading Artemis from a previous recommendation, I havnt yet finished it but this video enhanced my imagination! Glad to be a supporter!

[@L_mattox]

Isaac, if you see this comment, then I have a question for you. How do you feel about the Venus Project? If you've never heard of it, it's a sort of hypothetical plan for the future of politics, engineering, and human civilization as a whole. There's a few documentaries made by the Venus Project group, that they put up on KZbin for free. I don't remember the names of all of them, but I know the three main ones are "Future by design", "Paradise or Oblivion" and "The Choice is Ours". Anyway, have a good day.

[@DerekJones1081962]

I'm glad that you finally got around to fission as a power source. Solar while popular is inefficient in all the positive ways mentioned. Specifically smelting, which even on earth was more efficient using magnetic induction furnaces. Also, you didn't even mention ion drives and cesium being a by-product of fission being a useful constant acceleration and station keeping fuel.

[@TheBasqueWasp]

14:08 So why don't you just put the top of the elevator a little to close to earth so that it will be attracted to it. In that scenario it would be in a stable state, trying to fall to earth but held by the elevator's tension.

[@cannonfodder4376]

Yet another great episode Isaac. It still puzzles me that people obsess over Mars and still ignore the Moon and its importance to Space Industrialization and learning. So much at our grasp and still not grasped.

[@noddwyd]

Best part about this channel is the big picture thinking. It's not just a few things happening as the future develops, it's tons of things developing at once with multiple options for each area. Makes it harder for those dark dystopia futurology types to flourish. Or does it? Haha. You can always say this is just a simulation generated by aliens attempting to understand us in a safe way. AFTER they've already destroyed us. Totally safe that way.

[@Nikarus2370]

Thing I've not seen mentioned before. I recall reading a paper in college about pressing and sintering aluminum oxides. (Basically squeeze powdered aluminum oxide down, and then hit it with some heat. Not enough to reach the melting point [which for AlO is quite high] but above a certain point, it'll bond a bit). Thought is, that well the Moon doesn't have good access to one of the most important building materials on earth, concrete. So the paper was talking about how pressed-sintered alumina blocks could be used as bulk material when laying foundations, building radiation shielding, and etcetera on the moon, with a lower power demand to fully processing the material into aluminum.

[@izayakross7875]

2:54 this is the correct answer. Mass driver Its a faster, fancier, flat roller coaster track. All you need is electricity. and maintenance...lots and lots of maintenance...

[@thekaxmax]

side note: shipping H2 as ammonia is more volume-efficient than liquid H2, and because of tank differences is more mass-efficient. There is an efficient catalyst to reform it to H2 and N, and the N can be used for energy as well.

[@patrickcross1571]

Out of curiosity, why not simply put a particularly large solar plant at one of the lunar poles? If I recall correctly the moon itself doesn't have a tilted axis like earth does, so theoretically if you could build a plant with those following panels you mention in the video, you could have solar power ad infinitum limited only by time needed for maintenance. Something I'd also ask you to look at, coming from an urban planner-to-be here on earth; what about landscape preservation? This probably sounds stupid given the lack of delicate environments on the moon, but I feel like people on earth will sooner or later get irritated by the familiar sight of the moon at night being replaced by yet more urban sprawl. And what of spots with historic significance like the Apollo 11 site? Will they simply get built over with time?

[@michelejames8695]

Love your videos! So interesting!!

[@mattca353]

Its good to have more "near term" videos about how we will build a space infrastructure, especially as SpaceX is building Starship at breakneck speed and NASA going all in the lunar space station. I wouldn't be shocked that more than a few people watching this episode are already mentally preparing to work on these projects (especially with the first life extension therapies coming online very soon). Hell, i'm am one of them ;)

[@evensgrey]

We do have jobs where the standard work cycle is two weeks of working like hell, 12 hours a day, 14 days in a row, followed by two weeks off. This isn't easy, but some people seem to like it. This is usually things like offshore oil drilling (and firefighters, who at least in North America typically work 14 10 hour day shifts, 14 days off, 14 14-hour night shifts, 14 days off, repeat). This is rather like the situation for early Lunar installations, which will be places where you'll need to work like hell when you have the resources to do so, and just have downtime when waiting for whatever the limiting factor is (likely the energy to process the material).

[@gerogefinkle4764]

Ben Bova wrote an AWESOME book in 1981 titled "Welcome to Moonbase", I have read that book like a bible since I got it, hoping that I could influence that part of our future. This video reminds me a lot of the principles that he stated in his book, or course this is a nearly 40 year old book, and we are way more advanced scientifically. BUT still a good read, and a fun watch!
