AI Thread Summary
Humans settling on the Moon faces significant challenges, primarily due to high costs and the lack of technology for a self-sustaining colony. Current rocket technology is inefficient, expending most fuel just to lift payloads, which limits the feasibility of lunar settlements. Alternative propulsion ideas, such as laser propulsion and space elevators, are largely theoretical and would require immense engineering advancements. The discussion also highlights the absence of compelling reasons to settle the Moon compared to more accessible locations like Antarctica, where similar challenges exist. Overall, without breakthroughs in transportation and a clear purpose for lunar habitation, a Moon settlement remains unlikely in the near future.

What do you guys think about humans settling on the moon ?

Not anytime soon. Costs are way too high to place a permanent settlement on the Moon. Not to mention the fact that we currently don't have the knowledge of how to build a self-sustaining colony away from Earth, which only increases the cost since the colony would need to be resupplied in some fashion by Earth.

I don't think anything like this is going to happen before we have a way to get into orbit without using rockets. Rockets expend about 99% of their fuel just lifting their fuel. If we could develop a viable method to get vehicles into orbit without them having to carry their fuel with them, we could drastically cut down on costs and maybe, just maybe, start contemplating extravagant missions like this.

There are some ideas to get around the limitation of rockets, but I don't think any have gone much beyond sketches on paper. A big issue is that some of them, such as the space elevator, are such absurdly massive engineering projects that it's going to be difficult to ever get them off the ground.

How is it different? No matter what fuel you use (be it hydrogen or anything else) you are still limited by exactly the same problem.

Please remember hydrogen per se is NOT a fuel, it is just one of the fuel components - it requires and oxidizer to work.

Hydrogen is currently a common component in rocket fuel. The problem is that chemical propellants simply don't attain velocities high enough to get around this problem. Nuclear propulsion is quite a bit more efficient in terms of comparing the thrust to the mass of the fuel, but there are some pretty serious difficulties with getting large enough thrust to launch from the Earth's surface (safe nuclear propulsion has low power but lasts a very long time). There are some pretty clear radiation concerns related to increasing the power.

Some ideas I've read about that may (eventually) work out:
1. Laser propulsion: use extremely powerful lasers to push the vehicle into orbit, or at least to a pretty high altitude. The energy requirements are pretty ridiculous, so I don't know if this will ever be feasible.
2. Space elevator: Using carbon nanotubes, it's possible to build a tether to an anchor in orbit (presumably a captured asteroid). It would largely just be a matter of having the vehicle climb the tether to reach orbit, using a tiny fraction of the energy of an equivalent rocket. The biggest problems with this idea are that it would be an obscene engineering challenge, the carbon nanotubes are only barely strong enough (leaving little room for any engineering flaws), and the tether itself may have stability problems.
3. Space pier: Using synthetic diamond, it would potentially be possible to build a launch platform that reaches up into the upper atmosphere. Diamond has more than enough compression strength for a structure that reaches dozens of kilometers above the surface of the Earth, so it would have some leeway the space elevator doesn't have. But it'd be an even more ridiculously massive engineering project, requiring far more material than the space elevator.

All of these options are, today, rather absurd. They may never be done, and even if they are done eventually it could easily take more than a century to get engineering to the point where they're possible. But if we humans were ever able to get our hands on just one technology that didn't require us to waste 99% of our fuel, the solar system could easily become our playground.

It would be a lot cheaper and more productive to place habitat domes (or whatever) on the currently uninhabitable parts of the Earth, such as large deserts.
There isn't as far as we know any part of the Moon which has large amounts of resources that are not obtainable on Earth.
There is also no science goal I can think of, so this would be just one hugely expensive vanity project for whichever nation decided to do it.

Well, we do know of a way to extract energy from the vacuum: the Casimir Effect. Unfortunately, it's only an extremely short-range effect that likely has no possibility of use for propulsion.

Helium is one pretty major resource that's running out on Earth but pretty abundant on the moon. There are lots of others:
http://www.cnbc.com/2014/04/02/the-global-race-to-harness-the-moons-resources.html

But I'm pretty sure we need an alternative to rockets for this to become economical.

Also, let me just say that I fully support a vanity project like building a base on the moon. There are far worse things we are spending that kind of money on (such as war). If we could divert some money to do something like that, it'd be pretty amazing.
 
  • #12
I would certainly support your view that a project of this nature, even if not very productive, is a better idea than dedicating enormous amounts of resources to wars.
I don't think wars will end any time soon though, for some people wars are a good earner unfortunately, a moon base probably not.

A moonbase would have the same kind of profitability: the people that build the required components need to be paid.

Fuel costs are a small fraction of the total cost of rockets. It's the structure that holds and uses the fuel that costs. Also, with ~5% payload more than 5% of the fuel is used for accelerating payload.
There are some ideas to get around the limitation of rockets, but I don't think any have gone much beyond sketches on paper. A big issue is that some of them, such as the space elevator, are such absurdly massive engineering projects that it's going to be difficult to ever get them off the ground.
There are many ideas. Personally I like the StarTram approach, but it would be a massive engineering project. Not the biggest one, however, and not the most expensive one either.

Everybody's concentrating on HOW to go to the Moon. What about the less obvious question of WHY go to the Moon?

As a starting point, ask an even easier question: why not settle in Antarctica? It's remote, virgin, a lot like the Moon, only thousands of time cheaper, and opening a door won;t kill everyone in under a minute.

I'm not promoting moving to Antarctica, I'm simply pointing out that there's got to be compelling reasons to put up with the inconvenience and danger of moving to a remote, hostile place.

In most sci-fi universes, the Moon is either terraformed or possesses some unique natural resource that requires a large colony for extraction.

As for Antarctica, we do have habitats there, largely for scientific purposes. If we could make it reasonably economical to get to the moon, the moon would be an *amazing* place to do astronomy, for largely similar reasons that quite a bit of astronomy is done in Antarctica.

Right, but it's a thousand times more economical to settle Antarctica, and yet we don't start colonies there.

Again, I'm simply pointing out that the reasons we don't settle the Moon are the same as the reasons we don't settle any other less-than-hospitable place. We just haven't run out of room or resources here yet.

Running out of room or resources will never be a reason to settle on the moon or anywhere else outside of the earth. There just won't be any way to transport enough people to make any difference. The only reason that will ever make sense is adventure.

When I think of a moon base I don't think about ordinary people living and working there at all, I just think of it as the next step after the ISS , why do we go to ISS ? to do research on the effects zero of gravity etc on the human body etc and to conduct many other experiments . It can also serve a stepping stone to go to Mars. Martian geology and history is far more interesting for scientists now compared to the moon , we can learn how to manage the technical difficulties in a mission that can take years to complete, Mars might offers some unique challenges that the moon can't prepare us for , there are also discussions on the possibility of making rocket fuel on the moon using the water and other stuff available there but I don't think we have profitable methods for extracting them yet. http://www.dailymail.co.uk/sciencet...n-craters-help-signal-presence-lunar-H2O.html

Maybe the OP was a little vague, anyway if we build an ISS on the moon (LSS) given the amount of money and resources it will take, it will be a permanent base on the moon although it's inhabitants will be moving in and out.
We will need some kind of a profitable industry on the moon to keep the base running if we want a large scale human 'colony ' where ordinary people can live work and reproduce, I can't think of any profitable industry right now with current technology.

Moon has a lack of hydrogen, carbon and nitrogen. There are sufficient resources for technical infrastructure but not for life. Due to the resulting requirement of imports a colony would be limited in size and never independent. It would be doomed if the supply stops for some reason.

DrStupid said:

Most regions and even many countries on Earth are doomed without trade with others - at least if you don't want to fall back to pre-industrial levels.

Lunar regolith samples show up to 100µg/g for H, C and N. Source: Lunar sourcebook, page 444 (88 in the pdf). Not much, but a moon base would certainly try to avoid losing those elements, so a small supply can be sufficient. I guess (!) simply heating the rocks sufficiently in an oxygen atmosphere would extract a significant amount of those elements.

Yeah. I don't think the raw materials would be nearly as much of a challenge as all of the infrastructure required to maintain a self-sustaining environment. You'd need a huge colony to contain all of the necessary manufacturing infrastructure just to maintain the habitat.

You are talking about permanent settlement, with some kind of economy---e.g. manufacturing fuel, chemicals, material, equipment needed elsewhere---and self-sustaining. Well-shielded from radiation, vacuum, meteorites, cosmic rays. Growing its own food. Plenty of water and mineral elements.

I think the best prospect is in the subsurface ice layer of Ceres.

People on Ceres would manufacture stuff that is in effect already in orbit, because of low gravity. Could trade at a premium.
So that is a good site for human habitat, permanent habitation with a growing population. Deep enough in the ice to be well shielded.
Artificial lighting and heating would be needed. Nuclear reactor fuel have to be imported from Earth probably. Still a good economic prospect.

Better than moon, I think. Moon too much dry rock. Too much gravity. Big deal to land and take off.

A lunar space elevator is possible with current materials. It would probably need several rocket launches to get the material up (it cannot be too thin as it needs some resistance against micrometeorites), but then it would save a lot of launches as getting to the surface and back gets easier.

When China draws up plans for a moon base. I agree with @DaveC426913 that it's not economical, but there is an even stronger driving force in humans: the pissing contest. Landing there in the first place was anything but economical. Sure we got a lot of technology and the modern age out of it, but politicians don't care about what happens once they've retired and they stop needing donations. We went to the moon the first place for the sole purpose of getting there before the Soviet Union, we will do the same thing with China, I just hope this time around the contest will be more peaceful.

I don't think most people care about economy as much as they first appear to. We don't have enough money to take care of our own sick people, but we have enough to fight wars in the middle east. We don't have enough money to build new schools, but we want to build a giant wall on the Mexican border. If you call anything a threat to the United States, the ignorant masses will vote in hardliners. The SuperPACs and media will very much support it, the SuperPACs want people distracted from real issues and a Chinese moon base is even easier to sell as a threat than gays getting married. I think it'd actually be very simple to convince a large portion of the american populous to build a base on the moon. "If we don't do it, the Chinese will. Let's make american great again and beat the Chinese threat. God wants us too." I think that campaign would grow enough of a movement. Fear, Patriotism, and Religion. Three keys to controlling masses. It may not be right away, but I don't think the american people would be comfortable with a foreign moon base without our own. We can't build a wall between us and the moon.

The moon is a barren desolate rock. I can't see any reason why anyone would wish to "settle" on the moon, other than if it was a prison or a monastery/nunnery etc.

That's because national pride and jingoism is about " here is something I can do and you can't" attitude and planting your flags, collecting soil samples and not much more .After the competition is over people lose interest but the technologies developed will help the industry and future missions. Space settlements will take much longer time, money, dedication and a much better reason.

http://spacecolonization.wikia.com/wiki/Colonization_of_Ceres

I am no expert but the problem with Ceres seems to be is it's distance from Earth(for emergency evacuation or for supply of resources ,since we don't have any experience in building space habitats , it's better we start with something much closer to Earth )and it's very low gravity might be a problem for permanent human settlement but Ceres can be our interplanetary fuel station and a source of water and oxygen . If we can build a star tram or some other cheaper method of transportation on the moon or/and Mars Ceres can be good supplier of resources.Ceres can also be an asteroid mining station because it is relativity closer to the asteroid belt.
http://news.discovery.com/space/history-of-space/mars-prospecting-ores-gold.htm
Mars has water and possibly some ores , combined with resources coming in from Ceres will be good. I don't think the details of the feasibility will ever be worked out without a space race engaging different nations and private companies( if they can convince themselves of good returns )because right now there is no urgent need for a settlement outside earth.

We've already BEEN to the Moon quite a few times, starting in 1969(!), but we didn't stay long because we had to carry all our food, water and air. In the ensuing 46 years we may have learned a few things, but the technology required to build a colony in space was already old back then. What we need to work on is not so much propulsion systems as management of closed ecosystems -- the Earth being a less obvious but more important example. Unfortunately the Earth is so big that we fail to notice the effects of our mismanagement until it's too late. If we want to learn to behave more responsibly, the Moon is an ideal place to start.

Any sensible plan for getting off this planet, including L5 space colonies, BEGINS with a permanent Moon colony, if only to provide raw materials (Moon dust) to be smelted by solar mirrors in space into metals, oxygen and other essentials. Solar powered electromagnetic launchers on the Moon can easily fling buckets of dust out of the Moon's gravity well to factories at the various Lagrange points, obviating the fallacious necessity of lifting them from the Earth with rockets. Then we can really get started!

But NASA is embarked on an insane dead-end politician's fantasy of going to Mars BEFORE setting up a station on the Moon. This is a scheme guaranteed to sour everyone on the idea of putting humans into space. It is a suicide mission for NASA as well as the astronauts who go to Mars. What are they THINKING?!

I think NASA's primary objective on Mars is to find out if life is/was present on it. Sending humans there might get the job done quickly compared to robots which are extremely slow , NASA doesn't seem to have any plans for a human colony anywhere right now.

Yes but surely we can mine the rock here on Earth much more cheaply. Also the radiation on the moon could be a problem possibly? Finally, where would they get water and petrol from?

Also, any moon colony would spend 2 weeks in total darkness and 2 weeks in brutal solar radiation. I think the only possible use for it would be an orbiting prison colony for cimes against humanity etc.

Try this simulator - Orbiter 2010 - fly to the moon and back etc. You will find 1) it is not even slightly difficult to send a satellite to the moon; and 2) there is nothing to see there on the Moon - its just a big lump of inorganic rock.

Earth is so much better than the moon/rock. Earth has an atmosphere, magnetic shield, daily sunshine (rather than monthly on the moon), fossil fuels, carbon dioxide removal, perfect gravity for our species, oxygen and water production, stable temperature, seasonal variations, tides, the list is endless.

That's why you build underground.

We discovered large deposits of ice in some of the polar craters. That was a big deal a few years back, because water is one of the critical resources for a colony.

Petrol, not so much.
