Permanent human colonies on the moon? We like to think of it as our moon, but the Zhti Ti Kofft already have a base there. We are not powerful enough to force them off, and probably won't be in 20 years either. There is just no way they want to peacefully co-exist with us. After all they invaded during the balckout.
Fourty years ago, when the Americans were graring up for their first moon missions, the 'pundits' made exactly the same predictions.
Today it's the Chinese, but it all seems very similar.
Sure we've got better technology now, but will that really make the difference? Lunar colonisation will only happen when there's political will to see it happen, and frankly, I can't see the conditions being right for that for some time.
Well, I think the Chinese (and maybe Indian) governments *do* have the political will to go to the moon and stay there. By going to the moon, they send the world the message that they are just as capable a superpower as the United States. By staying there, they are doing something the American government cannot - or will not - do.
Excellent! So by the time we Americans get there, our lunar Walmarts will be fully stocked with cheap Chinese goods, and there will be a 7-Eleven in every major crater.
Typical BBC (and CBC, ABC, SABC, PBS) drivel that only the almighty Government can make something happen, and those mindless voters must be made to see reason.
Want space colonization? Try a gold rush... it worked in California, Yukon/Alaska, Australia (Vic), South Africa, and is currently populating parts of Brazil. So what do we need to start this gold rush?
First of all, higher commodity prices for things we'll find in space (metals, diamonds, power, etc). All these things are presently better provided (==cheaper) from terrestrial sources.
Second we need a frontier mentality that ANYONE may go out there and play. If they hurt themselves or get killed adding a mod-chip to their nuclear reactor, well too bad. If somebody does something bad, organize a posse and hunt them down. Only when the population gets big enough do citizens organize permanent posses and call them "police". Then and only then will the colonists form their own government and start paying taxes.
So we have a long way to go before real people have any need to go into space. We haven't finished mining Earth yet:-) .
I think all the Americans that think colonizing Mars is a good idea should attempt to colonize the Gobi desert instead. It's alot like the surface of Mars... BUT YOU CAN BREATH THE AIR!!!
Cripes, if the Chinese are willing to go all the way to Mars instead of colonizing the wasteland in their own backyard then America should explore there and spend the money they'll save on better observatories and robotic probes.

There are several reasons why someone might want to set up a base on the moon.
Because the moon has lower gravity, it would make an ideal space station.
The moon has a higher content of metals than the earth's crust. Plus, you can dig up entire craters and no one will notice. You can set up low-G manufacturing processes, dump all the waste chemicals into the moon, and no one will care.
Because the moon is on top of the earth, it is really easy to launch attacks on the earth from the moon with missiles or bombs. Whoever can get the hardware on the moon first will dominate the entire earth.
The problems outweight the costs. There's the whole problem of radiation. Solar flares release enough dangerous radiation that it would kill anyone who stayed on the moon's surface for an extended period of time. We would need a lot of shielding to protect us from it, more than is reasonable to manufacture at this time.
Also, launching stuff into space is one thing, but it is more expensive to get it to the moon and back.
When these two problems are solved, then you may see people beging to establish bases on the moon.

Why couldn't we have had humans living on the moon 20 years ago? Is there a technological reason? Afterall we could keep humans alive on the moon for a matter of days, all we'd have to do is launch frequent resupply missions and they'd be just dandy up there. Not really much different from the space station, except you get the added bonus of SOME gravity so maybe your bones won't complete decalicfy while you're up there. But there really are not pending technological obsticals to a moon base.
Now, weather a moon base is practical, usefull, or economically feasable is a whole another ball of wax, and the answers are probably all "no". What the hell are you going to do up there? I would like to have a ham radio linear transponder up there, but other than that what is the moon really good for? It can't be a RELIABLE communications satellite because it's only in the sky half the time and is very far away with a very high latency. It's got some rocks and minerals but nothing that would be worth flying back down to earth. Scientific research I suppose, but what could you do on the moon that you can't do on the space station for a lot less money, due to it being so much closer? Yea yea, a jumping off point for a Mars mission. See above, what is really the point to going to Mars? We still don't have the propulsion technology to make frequent Mars trips a practical reality.
One thing that could be a lucritive source of income for a moon base would be moon tourism. Perhaps the science could use it to fund itself, a la the russions and the space station.
IMO, before we even think about a moon base, we need to think long and hard about what the fuck we're going to do with it. Send more probes, shit send a thousand probes. Don't send big dumb expensive probes, send little cheap insectiod probes. Do the same to Mars. If there's something interesting there, we'll find it that way.
I know I know, if people said what I've said about the new world the US wouldn't be here. But the analagy with space is a little different. The "new world" was just another continent on earth. It had air, water, arible land, native people for which to enslave and abuse. Mars is a giant inhospitible desert with some frozen CO2 at the poles. Its possible we've overlooked something, but again it's a hell of a lot cheaper and easier to send probes.
If someone wants to squander their personal fortune on manned missions to Mars/Moon, go for it, but I'd rather my tax dollars be spent more efficiently.
I totally disagree. First off, the moon could be set up as a base to launch more investigative, futher expeditions into our solar system. (prolly for cheaper, cuz it wouldn't cost as much to blast off from the moon, due to lower gravity) Second of all, perhaps there will be a different set of minerals up there that we could start mining and build stronger, yet lighter materials. Remember, we're only on earth here, and what we see is only a product of what our earth can perform.

"Practical"
Let's see: - a nearly unlimited source of steel and other useful materials - no steep gravity well - lack of atmosphere means very efficient solar power collection, practically free energy - the moon is much closer than Mars Mean distance to moon: 384,000 km Mean Distance to Mars: 78,300,000 km Shortest possible Distance to Mars: 56,000,000 km
"Useful"
Some Idiot: "What use is this electromagnotism, Mr Faraday?" Faraday: "What use is a baby?"
The moon could be a staging area for larger trips, a cheap builing area for large structures and more. Commerse. Research. (yes, and tourism too).
"Economically Feasible"
How great inventions or explorations were able to turn a cash profit from day one? Isn't this a somewhat goofy yardstick for the worthiness of a human endevour?
Right now, it costs a bundle to move a pound of steel into space from earth. From the moon, it would be almost free.
And if that's not enough:
I want out species to survive. Genetically, we have all of our eggs in one basket. One accident, one asteroid, one war, one mishap with a supercollider or a nanobot or a designer virus, and we're gone. No backup. Gone. Any backup today is better than a great backup "real soon now".

Think about it. You correctly identified rays as going THROUGH the subject, to a hypothetic receptor on the other side. Obviously, for an image to manifest, the amount of energy that moves through the subject has to vary, otherwise the image would be all-white (or all-gray). Hence, we have some of the rays moving straight through, and the rest of the rays being scattered away. Some of those will be going straight back to where they originated from. Hence, you get just the same image (well, inversed) if you place the receptor right at the source.
They're gonna bounce the rays off its surface. You know, like you do with visible light? Its exactly the same kind of wave for christ's sake.
All EM waves are not equal.
Low-frequency waves, like RF and up through the microwave range, interact with matter like classical EM fields. They're reflected by conductors, and mostly absorbed by dielectrics.
High-frequency waves, like light (IR through UV), are in about the right energy band to interact directly with electrons in atoms. This process involves both classical and quantum effects. Because the energy structure of most materials is complex, you get complicated patterns of absorption bands and what not giving objects colour and distinctive spectra. In cases where an object has lots of free electrons, like a metal, the system is still close enough to the classical one to give reflection.
Really high frequency waves, like X rays and gamma rays, interact on pretty much an atom by atom basis with matter. Sometimes, especially with the low end of the scale (soft X rays), lattice effects in an ordered material will give diffraction patterns. For soft x-rays, you may also get interactions with inner-shell electrons giving absorption bands (gamma rays do the same thing with nuclei). Most of the rest of the time, though, you get scattering.
In summary, all photons are not equal. Shining an x-ray beam at a surface will give you some backscatter, as another poster pointed out, but what you're *not* going to get is diffuse or specular reflection like you'd get with visible light.

1KG of He3 is worth $6 million. Transportation costs to space and manufacturing processes need to come together...oh yeah, and we need to figure out that whole fusion thing. But once we're there, science knows of no better energy source (outside of anti-matter).
Why not just process He3 out of terrestrial helium? Sure, the ratio's about 1e-8 instead of the 1e-4 or so you have for deuterium, but you don't need a million tonnes of the stuff, and it stands a good chance of being cheaper to process it here than to haul the required large-scale strip-mining equipment to process it out of lunar soil.
D+D also works fine for fusion, with the drawback of your reactor vessel breaking down more quickly. Using D+He3 doesn't completely solve that problem, though, as parasitic D+D reactions occur even if you have a large surplus of He3 in the fuel.
For long-term space sources, we'd probably scoop-mine the atmosphere of Jupiter for helium to process instead of mining trace amounts from rocky bodies, but that's a far future consideration.
If we use fusion at all in the medium term, I suspect it will be D+D.
(D+T is much easier to reach breakeven on, but dumps almost all of its energy into neutron radiation, and requires you to breed tritium to sustain the reaction. This makes it a poor choice for large-scale power generation.)

What about launch bases on the moon? Escaping the moon's gravity to get to other locations has gotta be way cheaper than escaping earth's gravity.
In order to get to the moon in the first place, you need to have almost completely escaped the Earth's gravity, so it doesn't help for launch of things that are originally from Earth. Best approach for that is to launch them to as _low_ an orbit as you can (so as to minimize delta-v required of high thrust, low-Isp drives), and to spiral the rest of the way out over a period of months using a low thrust, high-Isp drive.
A network of these on the moon, maybe on one of mars's moons or mars iteself. I know, supplies need to come from somewhere, but shipping water from mars's icecaps to the moon might be cheaper than shipping water from earth to them moon.
This turns out not to be the case, as you need a lot of delta-v to travel from Mars's orbit to Earth's (the sun's gravity well is deep).
If a moon base was constructed, the best way to supply it in the short term would be to lift water and other hard-to-get commodities from Earth, and do your best to conserve them at the base. For long-term supply of extensive lunar or near-earth colonies, you'd probably tow an ice asteroid into one of the stable Earth/Moon Lagrange points, and mine that.
FWIW, a better supply chemical to lift from Earth would be ammonia. You can react it with oxygen from lunar rock to get water, and you can also use the nitrogen as a fertilizer component. Methane would also be a good choice. The moon has lots of oxygen, silicon, and metals, but lacks carbon, hydrogen, and nitrogen (which are all needed in fairly large quantity for earth life).
As for things to do on the moon itself, it's useful as a materials supply yard, but only if the materials are going to be used in space. Given the cost of building a lunar mining facility vs. the cost of lifting material from Earth, we'd only build a mining facility if we were building something Really Big in space for other reasons.

Correct. But it does help for things that are going to Earth. That is, a base on the Moon would be ideal as a place for docking spacecraft that shuttle back and forth between places (like mining the asteroids, for instance). The advantage is that you don't want to bother lifting the 'craft up Earth's gravity well when you don't need to, and of course, if you're transferring things TO Earth FROM the Moon, that's virtually free.
This only applies if the craft MUST dock, because even the Moon has a gravity well. If it can just jettison things, then hell, very clever orbital mechanics wins over the Moon any day.
But, it COULD be useful. It would also be more useful as a manufacturing plant for Earth satellites - launch cost of 2.3 km/s to GEO, rather than 13.8 km/s.
This turns out not to be the case, as you need a lot of delta-v to travel from Mars's orbit to Earth's (the sun's gravity well is deep).
Huh? Mars's orbital velocity is ~24 km/s, Earth's is 30 km/s. That's 5 km/s difference, and escape velocity from Earth is 11 km/s, and Mars's escape velocity is 5 km/s. As far as I can tell, if you escape from Mars's orbit, you'll basically fall back to Earth's orbit, free. I'm just doing back-of-the-envelope calculations, but it seems smaller to me (yah yah, I'm ignoring tons of orbital dynamics, but the points are ~roughly valid). I think the parent poster is correct.
Actually, a brief search online finds that I'm right, as shown here. The DV from Mars C3=0 orbit to Earth C3=0 orbit is 0.9 km/s - virtually nothing! delta-V from Earth's surface to lunar surface is 9.7+2.5+0.7+0.7+1.6 = 15.2 km/s. Delta-V from Mars surface to Lunar surface is 4.1+0.9+0.3+0.2+0.9+0.7+1.6=8.7, which is almost a factor of 2. I think more clever methods could probably be derived to lower that to less (using Phobos or Deimos for a gravity handle, if they're rotating in the proper way... I can't think off hand).
The Sun's gravity well is deep, but 1/r^2 wins every time.

Much as with lunar mining, this is only economical if you have a large amount of space traffic to and from Earth's region of space. No such traffic exists, nor will it exist in the near future. Even the arguments about towing metal-rich asteroids around only hold water if you assume the metals will be used in space.
So far, nobody's found a good enough reason to move people and industry into space in sufficient quantity to produce a need for space mining/storage.

You never "fall" between orbits. You have to make two course corrections - one from a circular orbit at Mars radius to a transfer orbit, one from the transfer orbit to a circular orbit at Earth radius - and neither is free.
Velocity at perihelion for the Earth-Mars Hohmann transfer orbit is 32.72 km/s, compared to Earth's orbital velocity of 29.78 km/s. Delta-v of 2.94 km/sec either to or from Mars, on this end. Velocity at aphelion for the Earth-Mars Hohmann transfer orbit is 21.48 km/sec, compared to Mars' orbital velocity of 24.13 km/s. Delta-v of 2.65 km/s. Total delta-v needed for a Earth-Mars or Mars-Earth trip: about 5.6 km/sec, and that's assuming that you start far enough away from either world for the gravitational well of each to be negligeable. That's true on the Earth end of things if you're starting from a high orbit (or a high lunar orbit), but not from the Mars end.
If you're going from Mars surface to Lunar surface, you need to add an extra 5.03 + 2.38 = 7.41 km/sec, for a total delta-v of about 13.0 km/sec. If you're just going from low Mars orbit to low Luna orbit, you only need to add about 1.47 + 0.70 = 2.17 km/sec, for a total of about 7.8 km/sec delta-v. Doing at least one of these is unavoidable if you want to actually carry material from one body to the other

The delta-v quoted by your source is far lower than the delta-v needed to get into a Hohmann transfer orbit even from free space in a circular solar orbit at Earth's radius (which the C3=0 orbit is the equivalent of).

As the Hohmann orbits are the lowest energy transfer orbits that don't require slingshots from other bodies, I question the values on that figure.
Ah, there's your problem. The C3=0 orbit is NOT a circular orbit at Earth's radius. It's a parabolic orbit with Earth at its focus, which necessarily can NOT be a circular orbit about the Sun at Earth's radius. A parabolic orbit means that at infinity, it will have no velocity relative to the Earth, which means, if the craft traveled to infinity, it would then have the equivalent orbital velocity of Earth. Problem is, it never reaches infinity, as it's not a two-body system, since the Sun's there.
If you want a spacecraft to be in a circular orbit at Earth's radius, well, it doesn't have to do anything - just stay home. It already is in one.:) After it lifts off, depending on the direction, it is doing two things - first, it is escaping from Earth's gravity, and second, it is changing its orbit. You don't have to "add" the escape velocities onto the necessary orbital delta-V. If you wanted it to actually reach a circular orbit, that takes a lot more work, actually!
This is the problem when you're doing "you need to add an extra 5.03 + 2.38 km/s" - you're adding the Lunar escape velocity and the Martian escape velocity, which you do not need to do, because you're not exactly going to infinity. On the return, you can easily aerobrake in Earth's atmosphere as well to enter lunar orbit.
Also don't forget about aerobraking! No matter what, any time you approach a planet (even entering lunar orbit! you can always place your perigee inside Earth's atmosphere with clever timing!) if you need to slow down, it's free.
And if you don't like that site, how about here, which shows that Deimos is more accessible than the Moon (and shows a delta-V from Mars surface to Lunar surface of 8.0 km/s, not 13.0 km/s).
Or here, where you'll note that "LEO to Mars" is a delta-V of 4.8 km/s, not the 5.6 km/s you're claiming - this is because, of course, it's in LEO, and therefore has some orbital velocity about Earth (and is therefore traveling at -greater- than Earth's orbital velocity at certain points).
I can continue to give examples if you want - the point is that from the Moon, it's easier to get to Mars and back than it is to get to Earth and back.
The easiest way to think about this is simple: You do not need to actually escape Earth orbit in order to reach Mars. A highly eccentric orbit can include both Earth and Mars (if both were stationary, obviously - they're not, so you can't orbit them, but you can of course use that path to transfer between them), and so must necessarily take less energy than the escape velocity of Earth+the escape velocity of Mars (which reaches Mars by going through infinity).
Interestingly enough, Hohmann transfers are not lowest energy. Google for "interplanetary superhighway", which is a relatively recent discovery. Really does suck that the 3-body system isn't analytically solvable...

It can actually be fairly cheap to launch from the moon, once you've covered the capital costs of setting up the launcher. You don't have to launch straight up; a tangent to the surface would do nicely. A very long solar-powered linear accelerator is practical on the lunar surface, because there's no air to provide drag. You might even be able to supercool / superconduct the electromagnets by tapping into the ground in a shadow zone. Not new, either -- read your Heinlein.

Wrong. Getting to the moon is about as expensive as getting to Mars, more or less, largely because Mars has an atmosphere that you can use to brake against for free. Only a fool would go to the Moon, stop there, then launch off again to go to Mars; for one thing, you're much more efficient doing your boosting near the bottom of a gravity well rather than at the top of one (em vee squared, dude).
Second of all, perhaps there will be a different set of minerals up there that we could start mining and build stronger, yet lighter materials.

Hm. True, but then you say...
The Moon is largely made up out of minerals we are quite familiar with here on ol' Terra[.]
Even more true! But then you miss the obvious - it shouldn't be that hard to flat out build spacecraft on the Moon (after all, they've got iron, silicon, etc.), and it's virtually free to launch craft into LEO/GEO/etc. from the Moon's surface (it's about 2 km/s delta-V or so needed, AND there's no atmosphere, so even something like an ion drive will kinda work - you'd still need a bit of an initial boost so you don't run into hills, etc., or a magnetic rail launcher).
If it wasn't for R&D costs and the pathetic state of automated factory technology (and/or the lack of a human base on the moon), fundamentally, you're better off building one factory 'craft, sending it to the Moon, and having it build 20 GEO satellites and launching them into GEO from there, rather than launching 20 GEO craft from Earth.
Note that I'm not talking about the current state of affairs - no way. But fundamentally, the Moon is a nice 'spacecraft launch base', but only if the spacecraft are built there.
Plus you have the added benefit of you don't have to pay for any of the materials. Though strip-mining the moon might piss some people off. Not me, though!
Even if the Moon would end up lacking certain critical materials (it is apparently short on carbon, though it's difficult to say what the subsurface holds), it's probably still a winning situation to ship up small amounts of the missing 'critical materials' (to make steel, for instance) as the materials available on the Moon likely would make up the bulk of the weight of the craft. You also have the added benefit that assembly in 1/6 gee is probably significantly easier for certain tasks than zero gee (and harder for others, but at least if you can't permanently lose bolts by bumping them:) ). With enough lunar infrastructure, a construction yard would make it EXTREMELY easy to build things on the Moon. You then have the additional benefit of not needing to put them through the utter hell of launching off of Earth. Most spacecraft failures and problems come from launch stress problems, and launch from the Moon could be (basically) as gentle as you want.
In any case, don't discount out the Moon as a launch base - you're definitely right that it's stupid to use it as a stopping point. It's NOT silly to use it as a future launching base and construction/assembly yard.

The delta-V is a function of the path; the required delta-V for a typical ion-drive trajectory is actually a bit higher than a two-impulse elliptical transfer. What's reduced by ion drives is mass ratio, which you would expect from the rocket equation.

It was clearly wrong (either erroneous or grossly mis-stated) the first time.
Getting to LEO from the ground requires roughly 5 miles/second of delta-V, about 8 km/sec. Getting to escape velocity requires about 7 miles/second, or 11.2 km/sec. If you chop 4 km/sec off the delta-V for escape, you're down to 7.2 km/sec and you will not even achieve orbit.

Sure they say they could have gardens, but that just is not enough when somebody wants to get out in the open..... They can also say that the colonies might provide suits to roam the outside, but the fact that people are in the suits seems claustrophobic
I guess it was persecution, but not in the way you probably mean - the first settlers in what's now the USA were Seperatists, who wanted to be able to persecute everyone else...
It could happen, but won't. Maybe that's a big call to make - things are advancing at an exponential rate and all that... who can really say what will or won't be done in 20 years time?
But I don't see it happening. For one thing it would be too vulnerable a target. We'd need to be pretty seriously close to some sort of worldwide peace.
Ah well.

Well I guess we would not make satellites either, it would be too vulnerable a target....hey wait a minute....
Whether something is vulnerable or not has little bearing on whether it will be pursued.
The ISS was vulnerable to micro meteors travelling at horrific speeds, yet it went up . Same with HST.
He3 is reason enough alone to send remote control mining to the moon.
I think we should delay sending man til the robots build it and test it thoroughly.
They do not need food, water, or air, just solar power and spare parts.
I say we start it now as a economic stimulus.
Supposedly there is over $100 trillion USD worth of He3 up there.
That is a good enough reason for me.
That would more than cover the cost of the robot portion of the project, and as cold as it is on the darkside we get free cryrogenics for superconductors.
The solar panels would work even better.
Satellites could largely be built and launched from the moon for much less by robots.
Spacecraft to travel to mars could be built and launched for the moon for much less.
In the long run it would end up saving money.

Just after I get my flying car!
Fourty years ago, when the Americans were graring up for their first moon missions, the 'pundits' made exactly the same predictions.
Today it's the Chinese, but it all seems very similar.
Sure we've got better technology now, but will that really make the difference? Lunar colonisation will only happen when there's political will to see it happen, and frankly, I can't see the conditions being right for that for some time.
(Spudley Strikes Again!)
Can I buy some land there? :)
I think it would be technologicly feasable to have people living on the moon in 20 years, but I don't think there will be a financial inscentive for the huge cost.
As x approaches total apathy I couldn't care less.
it will be China or India. The United States seriously lacks the resolve (or the infrastructure) to go to the Moon.
Maybe 20 years from now, we'll be surpassed in space and get shamed into exploring again.

Why couldn't we have had humans living on the moon 20 years ago? Is there a technological reason? Afterall we could keep humans alive on the moon for a matter of days, all we'd have to do is launch frequent resupply missions and they'd be just dandy up there. Not really much different from the space station, except you get the added bonus of SOME gravity so maybe your bones won't complete decalicfy while you're up there. But there really are not pending technological obsticals to a moon base.
Now, weather a moon base is practical, usefull, or economically feasable is a whole another ball of wax, and the answers are probably all "no". What the hell are you going to do up there? I would like to have a ham radio linear transponder up there, but other than that what is the moon really good for? It can't be a RELIABLE communications satellite because it's only in the sky half the time and is very far away with a very high latency. It's got some rocks and minerals but nothing that would be worth flying back down to earth. Scientific research I suppose, but what could you do on the moon that you can't do on the space station for a lot less money, due to it being so much closer? Yea yea, a jumping off point for a Mars mission. See above, what is really the point to going to Mars? We still don't have the propulsion technology to make frequent Mars trips a practical reality.
One thing that could be a lucritive source of income for a moon base would be moon tourism. Perhaps the science could use it to fund itself, a la the russions and the space station.
IMO, before we even think about a moon base, we need to think long and hard about what the fuck we're going to do with it. Send more probes, shit send a thousand probes. Don't send big dumb expensive probes, send little cheap insectiod probes. Do the same to Mars. If there's something interesting there, we'll find it that way.
I know I know, if people said what I've said about the new world the US wouldn't be here. But the analagy with space is a little different. The "new world" was just another continent on earth. It had air, water, arible land, native people for which to enslave and abuse. Mars is a giant inhospitible desert with some frozen CO2 at the poles. Its possible we've overlooked something, but again it's a hell of a lot cheaper and easier to send probes.
If someone wants to squander their personal fortune on manned missions to Mars/Moon, go for it, but I'd rather my tax dollars be spent more efficiently.

"...acording to a leading Lunatic Scientist"
somehow I don't think there is going to be a colony on the moon by 2023, I say we are lucky if we get a man back to the moon by then....
sigh....
--meh--
The article mentions: "The craft will make an x-ray map of the moon" in regards to the probe being sent by tht ESA. How, praytell, are they going to do that? You have to have a receptor on the other side of the x-ray beam, don't you? I mean, it's not like *radar* is it? Not the last time I looked...
So, what are they going to do, beam x-rays through the moon down to a receptor on earth or vice-versa? Somehow I doubt they'd get very accurate pictures.
Are they going to have the craft drop a plate off on one side of the planet, zoom across to the other side and take the picture?

The article just says it's technologically feasible. How boring.
In the movie The Right Stuff, and, IIRC in the book,a congressman says to an astronaut "What makes your rockets go up?" The astronaut starts to saying something about reaction masses and exhaust velocity, and the comgressman cuts him short and says, "No. What makes your rockets go up is funding."
Of course a Moon base is technologically feasible. Goodness, if we're just talking technological feasibility we should be able to be a lot more imaginative than that. (Project Orion, anyone?).
But unless someone "salts" the Moon with gold nuggets (I believe it's in Carl Sandburg's The People, Yes in which someone starts a rumor that there's gold on the Moon, and so many people start heading for the Moon that the person who started the rumor figures there must be something in it after all and joins them) I don't see how it's going to happen.
(Another nugget from The People, Yes "Another baby in Cuyahuga County, Ohio--why did she ask: 'Papa, what is the moon supposed to advertise?'" I'd give a nickel to know whether Heinlein read that before writing "The Man who Sold the Moon.")

On Earth 1 or 2 people die and we start inventing things to keep more from dying.
The Sol system is a little less friendly. A comet or other planet wide disaster is more likely to kill a very large portion of the planet, and totally destroy it's manufacturing infrastructure.
It would be far better to have a self sustaining economy away from Earth, one that could help rebuild our planet if BAD THINGS were to happen to it.
Before we can have a s.s. economy in space, we need to take first steps. We need to put people up there and find out what they need based on the circumstances, then we invent it and move on to the next thing.
The moon hopefully will provide enough resources for those living there to create what they feel they need.

The moon is a great place to send criminals. Send 'em there for life as involuntary colonists. Let 'em dig big caves.
As they dig those big caves they can grind the rock up for soil, melt pockets of ice that they find and use the water to grow wheat.
You put the wheat in big metal capsuls and you use a magnetic catapult to chuck the wheat down the gravity well to good ol' earth.

What about launch bases on the moon? Escaping the moon's gravity to get to other locations has gotta be way cheaper than escaping earth's gravity.
In order to get to the moon in the first place, you need to have almost completely escaped the Earth's gravity, so it doesn't help for launch of things that are originally from Earth. Best approach for that is to launch them to as _low_ an orbit as you can (so as to minimize delta-v required of high thrust, low-Isp drives), and to spiral the rest of the way out over a period of months using a low thrust, high-Isp drive.
A network of these on the moon, maybe on one of mars's moons or mars iteself. I know, supplies need to come from somewhere, but shipping water from mars's icecaps to the moon might be cheaper than shipping water from earth to them moon.
This turns out not to be the case, as you need a lot of delta-v to travel from Mars's orbit to Earth's (the sun's gravity well is deep).
If a moon base was constructed, the best way to supply it in the short term would be to lift water and other hard-to-get commodities from Earth, and do your best to conserve them at the base. For long-term supply of extensive lunar or near-earth colonies, you'd probably tow an ice asteroid into one of the stable Earth/Moon Lagrange points, and mine that.
FWIW, a better supply chemical to lift from Earth would be ammonia. You can react it with oxygen from lunar rock to get water, and you can also use the nitrogen as a fertilizer component. Methane would also be a good choice. The moon has lots of oxygen, silicon, and metals, but lacks carbon, hydrogen, and nitrogen (which are all needed in fairly large quantity for earth life).
As for things to do on the moon itself, it's useful as a materials supply yard, but only if the materials are going to be used in space. Given the cost of building a lunar mining facility vs. the cost of lifting material from Earth, we'd only build a mining facility if we were building something Really Big in space for other reasons.
can we call it a repeat even if it's "new"?
I'll turn into a supernova and burn up everything. Well I'll turn into a black little hole and you'll turn into string.
The writers and producers of the science-fiction classic, "Space 1999", were off the mark by about 25 years. "Space 1999" was broadcast by NBC in 1975 and dealt with the lives of colonists on a moonbase called "Alpha". The series began with an episode where a nuclear explosion hurls the moon out of the earth's orbit. Each succeeding episode of the series descibes the dangers that the colonists face in space.
Quoth the poster:
Wrong. Getting to the moon is about as expensive as getting to Mars, more or less, largely because Mars has an atmosphere that you can use to brake against for free. Only a fool would go to the Moon, stop there, then launch off again to go to Mars; for one thing, you're much more efficient doing your boosting near the bottom of a gravity well rather than at the top of one (em vee squared, dude).The Moon is largely made up out of minerals we are quite familiar with here on ol' Terra, and nature has done us a favor by differentiating them using water-based sorting processes which don't exist on Luna.

The delta-V is a function of the path; the required delta-V for a typical ion-drive trajectory is actually a bit higher than a two-impulse elliptical transfer.
Let me clarify - you shave 4 km/sec off the delta-v you need to produce using chemical rockets.
An ion drive with an Isp of thousands or better can use even an inefficient transfer scheme and use only a little fuel. Adding 4 km/sec using a rocket with an Isp of 300 gives you another factor of 3+ on the fuel:cargo ratio.
Seriously though, there would be huge benefits if we could arrange a permanent outpost on the moon. It's certainly possible to do so within 20 years, hell the US sent a man to the moon after ten year research. The problem? Designing and building any form of outpost would require international cooperation. The ISS is a good example of what's possible and what can go wrong.
Sure we can stick a few people into the ISS for 6 months, but the moon is another matter. It's unprotected by Earth's magnetic field, so radiation is a huge problem. It's too far away for us to do anything if something serious happens accidentwise. We don't yet have any economic reason to bother sending a permanent outpost there.
The moon will eventually be colnised for its resources, but not in the next twenty years, probably not in the next 40 yrs either. I expect to be dead and buried long before the international community discover a reason for sending people out to live there permanently or semi-permanently.
"Take the prisoner downstairs," Tom said condescendingly.
Getting to LEO from the ground requires roughly 5 miles/second of delta-V, about 8 km/sec. Getting to escape velocity requires about 7 miles/second, or 11.2 km/sec. If you chop 4 km/sec off the delta-V for escape, you're down to 7.2 km/sec and you will not even achieve orbit.
You're right about the mass-ratio, so I suspect that you're just fumbling the expression of the concepts. A forum like Slashdot isn't a good place to do that; there are too many people out there who accept any authoritative-looking thing as gospel. While they may well deserve what they get, I think it's incumbent upon those of us who actually know something to try to help the public understand things rather than obfuscate them.

Sending ppl up there is just cost prohibitive
But if you think a little like Isaac Asimov, then sending
robots makes perfect sense
You send small robots up there that can be remotely controlled
from earth, and have Xmit/Rcv stations at different locations
around the globe
You bring in several countries and even companies on the project,
split the costs, and write a agreeable charter
One country footing the bill imght be high, but if 10 did it ???
As there is almost no atmosphere on the moon, so Solar works
VERY well up there
As it is VERY cold on the dark side of the moon you can use
that for refridgerant purposes, ie. cooling
Once a LARGE Solar array is built, air scrubbers similar
to what was in the old space capsules of the 60's could
be built and an underground network or redundant tunnels
could be dug . Better tech is now available
Make all the equipment electrically powered, and excess
electricity can be used to process mined ore
Not enough electricity , then the ore sits around awhile
Trying to fly all the materials to the moon is crazy,
have the raw materials there built into what we need
I think China is thinking this, thus there comment
they intend to mine the moon
It is not going to be easy, that much is sure, but alot
of our manufacturing here on earth has already alot of
robotic elements
Auto worker unions fought against the further invasion
of robots into car plants
This tech and this mindest could build the moonbase
and make it inhabitable prior to humans ever setting
foot in there
If the chinese are smart they will do it this way, and
to be real honest, this way nobody dies
Once the moonbase has run on automated systems and taken
a meteor or asteroid hit without being destroyed , then
it is considered safe for a large scale move in of scientists
Shielded by 100's of feet of moon dirt, ppl could live and work
there to build space stations, space craft, more solar arrays,
build a truly GIANT low gravity telescope on the moon
Think zero light pollution on the dark side of the moon,
think of a radio antenna twice the size of the Aericebo array
Alot of truly GREAT things could be done on the moon

would need to largely live underground
Several hundred feet underground in circular tunnels
similar to those going under the english channel
The cost of tunnelling has dropped due to projects
and tech derived form it like "The Big Dig" in Boston
The moon base should be built by robots running off
a Solar array set up on the moon, by said robots
The robots need to be able to diagnose and troubleshoot
each other, and repair each other
Like a linux cluster if a percentage of them goes down,
then it just functions at lower capaciy, but progress
is still made
Every so often spare parts are sent up and land similar
to the air bag landing used for the mars rover
Solar power is much stronger on the moon as it nearly
has no atmosphere
Feeding, Breathing, Sleeping humans would be too expensive
to put up their initially and the Biosphere here in the
US failed in its testing
Have the robots work the kinks out
Humans can go up there once the moonbase is finished and
testing is complete
Several nations should join together to shoulder the
burden and share the rewards

The dark side of the moon would make a great place for
a Telescope roughly 3 or 4 times the size of the
Keck telescope in Hawaii
The solar power on the moon would be very plentiful, and
we could build the majority of this with robots and remote
control systems
Yes, there is a 2 second dealy, but we have a further dealy to
mars and use the rovers there in a similar manner
Build the moonbase underground for insulation , and for
shielding against cosmic rays
Have humans show up only after extensive testing proved
the moon base was safe for humans
Have redunant power and life support systems to keep
it that way too

I think it would be alot easier to have robots land on it,
mine it, and rail gun it to the moon
Then use it to build space craft or whatever on the moon
If the earth is wiped out due to disease, nuclear war,
or some other human engineered disaster, we need a backup
plan , and the moon is the closest one to us
A moonbase is a good idea, all the He3 up there is a good idea
We can use the MUCH stronger solar power up there to make it work
We have robots build it around the clock 24 x 7 not needing air,
food, water or rest, just spare parts
We send spare parts up in a air bag delivery system similar to
what we sent the mars rover in
The asteroid belt may hold more mineral wealth then we could
feasibly mine here on earth
It is easier to move tons of the sutff around in zero gravity too
I think robots are the way to do it, humans would die, and
would cost alot more than robots would
We form a group of concerned countries and co-fund it
10 major nations funding it could bring it in collectively cheap
