el crowbar sent us a link to an MSNBC article detailing NASA's plans for a moon base. The permanently staffed structure could begin construction sometime in 2010, with six-month duty rotations the norm by 2025. Interestingly, the space agency is looking far afield for technical expertise. Consultants on the project include individuals from Caterpillar, Norcat, Boeing, and other manufacturing concerns. Right now the only detail for placement and purpose is 'on the rim of a crater near one of the poles', but the article outlines a few other ideas that enterprising individuals have in mind for a moon base. Besides helium-3 mining and lunar hotels, do you have any good ideas for a moon base startup?

Yeah, you can tell the American touch has been put on these plans (Note, I am American). Any chance we can put some government offices, maybe a DMV or something?

From TFA:
I think we should start by getting a few moon facts straight before we progress to a permenant settlement:
So if it was going to lose line of sight occasionally it would be on every lunar orbit, not every year. The lunar axis of rotation is so close to the orbital plane around the Earth that a polar station will never see the Earth move significantly in its sky.
If anybody is interested my preference would be for a heavy, pressurised rover. Capable of autonomous driving and control from the ground. Each new crew lands close to the path of the rover and drives it for a week or so. They then meet up with another lander and use its ascent stage to return to Earth. Some ascent stages are landed under remote control so that the first crew can use one to return.
The problem with a fixed base is that the local area will get boring pretty quickly, so a pressurised rover will be needed in any event. If the rover only drives at 10km/h the whole habitat may just as well be on the rover. It can drive fast enough to always be in sunlight, so you don't have to worry about energy storage at night.
Ascent stages are flown down under automatic control, or left behRe:Make it mobile (Score:5, Informative)
That's not entirely true. The earth rises and sets in places all around the moon's circumference as seen from the earth, not only at the equator. The effect that makes the moon's face as seen from the earth move a little bit is called "libration". There is libration both in longitude and in latitude. For some points near the poles of the moon, libration in latitude can make the earth invisible at times. Formulas for calculating librations can be found in chapter 53 of this book [willbell.com].

How about.... a solar forge, melting down local ore, bubbling a gas through it (lower gravity means more spherical bubbles, better strength) to make foam alloy structural elements, then putting it on your solar powered catapult to shoot into orbit for either a) recovery for earth use via semi-controlled re-entry or b) orbital construction.
Low gravity ceramic compounds would be interesting also.

Electricity could be provided from solar power, since you would have areas that always receive direct sunlight. At first a large scale Radioisotope Thermoelectric Generator could provide more than enough power.
I may be a pessimist but it's my belief that the key to long term human survival (as a species) requires that we find a way to get off this rock and not just for 6 months but indefinitely. The moon seems like a very good start. Once we learn how to survive there the prospect of permanent colonization of an actual planet, like Mars, would be cake.

Builds require structural materials to maintain their integrity, which means mass to haul into space
There is no protective atmosphere on the moon, so the structures are SOL if a rock happens to come wandering in from space, barring LOTS of mass for protection. (Yes it can happen - where do you think meteor showers come from?)
Radiation on the moon's surface is also not cut down, so same problem as incoming high speed rocks. Materials durability concerns, people concerns, all sorts of fun.
If we put the sucker underground, we get a nice layer of rock on top of the base, which will neatly avoid getting lots of support materials up there and will protect everyone. It would also provide thermal inertia against extreme temperature swings, reducing energy and insulation costs. Sure the view would suck, but I'll bet after a while the view on the moon would get old too. Have a viewing station above for observations/airlock/what have you, but build the bulk of it underground. The moon is relatively stable geologically and the far more active Earth has plenty of underground structures on it, so the real question is digging it out.
So I would suggest looking at ways to hollow out large areas on the moon with minimal equipment. My first thought would be small, low mass automated diggers running off of solar power feeds working slowly over time, so we can learn about the environment as we dig into it. Easy to get up there, and over time they could do serious work if built reliable (think filling up a swimming pool one drop at a time, just in reverse.)
It wouldn't have the neat "space base!" look you see on the covers of science fiction books, but I think it would be much more practical, safe, and useful.

Re:corporate welfare (Score:5, Insightful)
That's harsh. Apparently corruption managed to land us on the moon, send dozens of probes out into the solar system, and built an International Space Station complete with the capability to take routine space trips every 4 months. If NASA did all of what it has done while being nothing more than a tool for corporations to steal government money, then shit, sign me up to be a congressional lobbyist- I might cure world hunger.
I'd prefer to see the space program killed altogether and NASA disbanded instead of having taxpayer money wasted on moon colonies and manned trips to Mars.
This is definitely not a waste of money. Once this industry gets started, the possibilities are enormous. First think of the political implications of having a thriving off world colony. What if we could move UN headquarters to Lunar City, the first truly international city? What would it mean for world unity, for peace and human progress? You're worried about the cash? Well the first thing they told me in economics is that technological innovation drives the economy- we were an agricultural planet until technology came along and forged the industrial economy. The technologies developed to build a moon base would filter down, as they always have, and invigorate the economy. Then think about the industry that would follow, that would benefit Earth: off world manufacturing that would get pollution out of our fragile ecosystem, off world (solar) energy generation, off world disposal of hazardous waste. Did you know that on earth, Iron, the most commonly used metal, is mined from Iron Oxide- rust? Did you know that rust is literally covering the surface of mars? It might even get cheaper to extract Iron from Mars than on earth if we keep up this exploration nonsense.
And best of all, think about the scientific opportunities space bases would allow us. A perfect, undisturbed view of the heavens. Super ideal experiment conditions in the form of vacuum and free fall. Greater access to natural resources for particle physics- research stations on mercury interacting with the sun, or on pluto interacting with nothing. Advances in bio-chemistry that would come from vastly improved understanding of planetary/atmosphere physics and chemistry, and study of asteroids and comets, as well as above mentioned 0 g and vacuum. All these opportunities are only accessible if we make a serious, money losing push at first.
I get your cynicism as to the intentions of the politicians but realize, it's not the politicians or the people who are interested in huge profits who are doing this (there are vastly better industries to make money in than space). It's the people who are passionate about such things. And while it may just be another project for the politicians, for the people who choose to devote their lives to its pursuit, space is much more- and it is something worth going about correctly and responsibly. People willingly sacrifice their lives in return for the chance to explore space. To say that NASA is a waste of taxpayer money and no better than waging a war...
Re:Other uses - make it a colony, not a base! (Score:5, Insightful)
That's somewhat impractical and slightly redundant. Presumably the point of a moonbase is to develop the technology and techniques needed to develop colonies in the future? "Importing as little as possible" is an easy thing to say, but a lot harder to do. Even here on earth we find it hard to grow enough food in enclosed environments, what's it going to be like in space?
It's worth looking back at human history for lessons on colonies, in fact probably the colonization of North America is the most enlightening and best known. American colonies, whether English, French, Spanish, Dutch or Danish, all had two things in common:
- They were expensive
- They had a low success rate
They all had to import things initially (food, people, tools) and they had their own set of problems (disease, climate, natives), but generally colonizing a different continent is a lot easier than a different planetary body. Despite this, most colonies failed miserably. Some of the common reasons for failure included:Basically, for a variety of reasons, a self sustaining colony cannot be instantly setup, it always needs expensive support from the homeland until it has adjusted to its new environment. However a few colonies were worth the initial huge cost (in both currency and lives) to keep them maintained, the reasons for this include
To cut a long and interesting story short, the successful ones all made money. In the case of the Spanish they literally brought it home in the form of gold, for the English and Dutch new trade goods and markets and the taxes on trade did it and the French, well, are generally a lesson in how not to do it.
Any extra-terrestrial colony is only going to be a long term proposition if it makes more than it costs. Obviously no body, private or public, is going to throw money at a colony just for the sake of having it there (small scientific outposts excepted). With a current average launch cost of about $10,000 per pound one-way (I think) the moon is going to have to produce or allow production of something pretty fucking valuable to allow a permanent colony to grow there (and there are no new markets out there).
Assuming you can find that thing then you have the next problem of free market economics. Anything that costs $10,000 per lb is going to be sought after and extremely rare on Earth. As soon as you start transporting it back from the moon in practical quantaties (say one full shuttle load) it's no longer going to be rare and the price is going to drop, or, in the case of something that expensive, more likely plummet. I'm not an economist, but common sense tells me the chances of the price staying high enough for long enough to even break even is negligble.
The other end of the problem is to lower launch costs of course. I'm not really in the loop anymore but I think the current thinking is that things start getting interesting when launch costs come down to <$500/lb. That's a twenty fold decrease. A jump of that magnitude needs a technology revolution, not just tinkering with existing techs.
There are many obstacles to permanent ET colonies but the biggie is always the cost of overcoming that pesky gravity field we have. Whilst going to the moon may be fun, and incidentally show those Chinese who's who, I can't help but think that the money would be better spent in this direction.

So if you value permanemnt human space settlement in it's own right, the aim should be for it to exist for it's own sake. Best way to do this is to make it "home" for people. For this, you need it to be as self-sustaining as possible. Once the colony got big enough, it may be able to host greater scientifict research, and also work as a launch platform for deeper space exploration.
I have no idea if this is more cost-efficient than putting the money into development of exotic launch technologies here on Earth tho'. It may be, but it may also be that those projects has a lower return on the investment than learning how to "seed" new colonies out there that can aid further exploration of space (and secure humanity).
