It's been a while since I ran the numbers (I used to work for Boeing in an advanced projects group) but running a Mars mission with lunar fuel and oxidizer makes a BIG BIG BIG difference in the feasibility of it. Say you have a Mars ship in Earth or lunar orbit with empty tanks you've got to fill. From Earth you use the Shuttle, and it takes a full external tank and hundreds of millions of $$$ to get a Shuttle-cargo-bay-sized slug of liquids into your Mars ship tanks - many many shuttle missions and $$$ to fill them. It takes a LOT fewer pounds of fuel to lift the same hydrogen / oxygen from the surface of the moon to fill those same Mars ship tanks. It's the same as running a war - everybody wants to be on the tank that rolls into liberate the city, but in reality the war was won months before by the logistics and supply lines that made that final push possible.

      Although Ben Bova's _Welcome_to_Moonbase_ is approaching its 15th birthday, it remains a provocative look at commercial and scientific exploitation of the moon's resources.

      Commercially, the moon is a cheap source of materials needed for large-scale construction in space. Oxygen and aluminum are readily-available propellants. Aluminum is a good structural material, particularly in the moon's weaker gravity. Solar panels and reflectors can provide cheap heat and electricity. Metals can be refinend and oxygen extracted by melting lunar soil, capturing the escaping gases, and allowing the result to separate as it cools. The moon's atmosphere is almost nonexistent, providing a free vacuum several orders of magnitude better than the best commercial installations, and the thin atmosphere is very clean, virtually free of dust above one to two meters above the surface.

      The ability to cheaply manufacture and launch satellites, probes, and other vehicles means direct observation of planets, asteroids, and comets could be conducted many times more frequently. The moon, while it lacks the earth's large shock-absorbing core, is a geologically quiet base upon which to build a massive telescope or array, with the entire mass of the moon insulating it from the sun's radiation, and virtually no atmosphere to distort the image. Even the mere fact of having scientists in long-term direct contact with another solar body will enormously expand our knowledge of the universe. Studying the earth, we can only hope other places are similar, but studying the moon as well means we can make generalizations with much more confidence.

      I don't think any one company is rich enough to set up the infrastructure needed to be sustainable and commercially successful, and no government can dump that much money into a project with no short-term returns. We can only hope that several companies can cooperate either on one project or will develop complementary projects. If several groups are planning on trying to setup installations on the moon, it might be profitable for another organization to setup an installation whose sole purpose is to provide materials the others will need. A small automated facility which extracts oxygen from the soil could save a dozen other installations the expense of setting up their own oxygen plant. Another installation could extract only aluminum and sell that for construction of its neighbors, perhaps paying for its oxygen consumption in aluminum used to expand the oxygen extraction facility.

      I'll be the first to admit this sort of closed economy cannot sustain itself and must eventually reap some financial reward for the companies on earth, but cooperation between enterprises makes everyone's barrier to entry that much lower. As soon as the infrastructure is setup to mine and use materials from the moon, construction there should be immediately financially rewarding and should create a scientific and manufacturing boom. Once we reach that point, it's all downhill from there. The problem is the financial risk involved in getting to that point. Hopefully the lure of potentially vast riches will bring in the necessary funding.

The specific impulse (measurement of efficiency) for such an engine is in the 480-500 second range, which trust me, is really really good and probably represents the practical engineering limit on what is going to be built. Going beyond this would require using something like using extremely corrosive liquid florine or chlorine and that ain't gonna happen. The space shuttle main engine (SSME) is the best rocket engine in this class and probably a derivative of the SSME is what would be used on a chemically-fueled manned Mars mission. (If you go with a nuclear rocket for a Mars mission, liquid hydrogen is still the best choice as the working propellant, tho you'd need a lot less of it due to the fact a nuclear reactor could heat it much hotter than chemically combusting it with LOX in a SSME).

      Ice from Earth's South Pole would work fine as a source of hydrogen and oxygen to fill the tanks of a Mars ship, except for one little detail - YOU'VE GOT TO GET THE ice/oxygen/hydrogen FROM EARTH'S SOUTH POLE TO THE ORBITING MARS SHIP. This means fighting 1G gravity PLUS a thick atmosphere to get every pound of Mars fuel in orbit. Move the ice/oxygen/hydrogen from the MOON'S south pole and you ony have to fight 0.18 G gravity and no atmosphere to get it to the orbiting Mars ship.

      The energy required to do these two tasks doesn't scale linearly - it isn't six times easier to lift off from the moon because it has one-sixth the gravity of Earth. It is a LOT more than 6 times easier to get a pound off the moon than a pound off of the Earth. That's why a Saturn 5 was 365 feet tall and a lunar module was only 20 feet tall. (Well, yeah, I know the Saturn 5 had to lift more weight than the LM, but I'm going for mental illustration here. There is no such thing as a 20 foot high rocket that can lift ANY amount of weight from Earth to orbit, not even a few ounces...)

      So the final point remains, if you're going to mine something from the moon, your best bet is not to bring it to Earth but to take it to some orbiting launch site and use it to go somewhere else like Mars. Being on the moon puts something a lot closer to being available for use in space than being on Earth does.

Some Russian designs for space flight produce 5-6KW, still an order of magnitude too small to run a small crusher.

What we did find ruined a great many of the existing theories about the moon, and it seems likely that there are just as many bombshells up there remaining to be discovered. All we have right now are theories, based on a very incomplete sampling of facts.

    One other big point you're missing is that the minerals and raw materials mined on the moon would have a far greater value in Earth orbit than they would on earth. In orbit, the $10,000 per pound you mentioned is ADDED to their value. How much would NASA pay for aluminum girders and panels that are already AT ISS? Sending them to Earth orbit from the moon is also far cheaper than returning them all the way to Earth.

    There are also far less environmental problems with mining the moon. By any reasonable definition, the moon doesn't HAVE an environment to spoil. On the Earth, there are profound cleanup-related issues that are only now beginning to be reflected in the costs of things.

    I will say that as far as the amount of legal objections you have to put up with goes, mining on the moon could be as bad as mining on Earth. I'm sure the far left will come up with some reason to sue endlessly.

  49. Re:Pt and Ti not interesting at nearly 70K$/troy o by hey! · · Score: 2

    The costs were based on the total mission cost from a '67 contractor memo I googled off of NASA's web site (sorry, don't remember the exact search). It was a starting point for some very vague back of the envelope estimations, some of which were wildly optimistic, a few somewhat pessimistic. It tells me that we have to be about a thousand times more efficient (which may well be possible) to justify going there to pick up already processed material (which won't be waiting for us ;-).

    Actually, the surface of the moon is already covered with lunar material that has been broken up for you: it's called "dust." Smashed up by millennia of impacts from meteors, asteroids, and the like. Look anywhere on the moon and you will find many tons of it. I'm not sure what the depth is, though, and it may vary.

    However, you really have the same problem: you've got a huge amount of dust to process, and that takes very large machines and lots of energy to run them.

    Moreover, the astronauts did in fact find concentrations of minerals in the moon rocks they sampled, and this was found while moving at a five-minute-shopping-spree pace, mind you: their time on the moon was extremely valuable, and they were constantly hurrying to get everything done.

    Well, on earth, you find concentrations of valuable commodidites in various rocks; even in common seawater. However, most sources of valuable metals that are economically feasible to exploit have been conveniently concentrated into seams by geologic processes that do not exist on the moon. As you point out there may be concentrations of materials on the moon formed by other processes, we just don't know.

    One other big point you're missing is that the minerals and raw materials mined on the moon would have a far greater value in Earth orbit than they would on earth.

    It's an interesting point, but I suspect that the cost of fabricating hardware is going to be much higher on the moon than the cost of launching earthmade hardware, until the initial cost of the lunar facilities has been amortized over LOTS of orbital projects. In other words, to help build a relatively small project in Earth orbit, you'd have to build a much larger and more complex project on the moon first -- it just isn't an immediate help. However, if you were building a VERY large orbital structure or a large number of structures then lunar or asteroid mining might be a sensible option to pursue.

    Left-bashing aside, I think you overestimate the mining company's political clout. They can pretty much come in, liquidate an area, take their profits and disband before they can be held to account for any damage. On the other hand, getting the amount of nuclear fuel to the moon you'd need to power a major mining operation would be a huge political and legal mess.

    In any case, it's not that I don't want it to happen; I just think its very unlikely.

    No offense, but it seems to me your numbers are at best somewhat suspect. : (

    However, you really have the same problem: you've got a huge amount of dust to process, and that takes very large machines and lots of energy to run them.


    Wrong, since the dust is already ground up finely, most of the work is already done. The next stage might be to sift, maybe separate magnetically, and then to heat up batches of the dust and melt out the metals. Not a lot of machinery needed. And, you have lots of free solar energy to work with, assuming you base near the poles, so that you can gather solar energy all the time. Particularly good when you just need to melt stuff: you can focus the sun on it using big mylar mirrors.

    Well, on earth, you find concentrations of valuable commodidites in various rocks; even in common seawater. However, most sources of valuable metals that are economically feasible to exploit have been conveniently concentrated into seams by geologic processes that do not exist on the moon. As you point out there may be concentrations of materials on the moon formed by other processes, we just don't know.


    As I pointed out before, mankind has spent a total of, what, a week and a half on the moon, in scattered areas, getting at best an initial sampling of data. We don't KNOW whether minerals are concentrated anywhere on the moon or not. Detailed surveys have not been done yet.

    It's an interesting point, but I suspect that the cost of fabricating hardware is going to be much higher on the moon than the cost of launching earthmade hardware, until the initial cost of the lunar facilities has been amortized over LOTS of orbital projects.

    You suspect, but do you have numbers?

    Fabricating parts remotely is getting very easy to do, if you use 3D printing/sintering technology. They're used in rapid prototyping now. They can literally print out a metal part one layer at a time, with very good tolerances. This is a machine the size of an office photocopier. Sending one to the moon would be very feasible. They require metallic powder to work with, which is coincidentally what you might expect to get out of your dust-mining operations.

    Building electronics would be more difficult, but you would have lots of good clean vacuum and power, and raw materials.

    I am sure, though, that there would be dividing line at which it would be cheaper to ship some components from Earth than manufacture them locally. If it's only some parts, though, and they're electronics and gaskets, you could carry lots of them for not too much weight.

    Would it actually be commercially feasible? I honestly don't know. I admit I want to see it tried, though, because I'm a hopeless space fanatic. One thing is certain: it IS getting easier all the time.

    On the other hand, getting the amount of nuclear fuel to the moon you'd need to power a major mining operation would be a huge political and legal mess.


    Firstly, most of your power could be solar, if you're close enough to the poles to have power plants in sunlight all the time. Secondly, one of the major promising finds on the moon is large amounts of Helium-3 in the lunar dust and everywhere else, which may prove to be an excellent nuclear fuel. There is still a lot of research on fusion power that needs to be done on that, I admit, and there is a possiblity that it might not come to fruition in our lifetimes, but it is promising.

    Let me say I respect the fact that you're trying to stick to facts. But, there is a lot of work that has been done on this subject, much of which is very encouraging. I'm sorry I don't have links at hand, but you might check in on the sci.space newsgroups to find more detailed info.
