I am reading #Seveneves which is about exactly that!
great book! the last third wasn't my cup of tea though.

Based on Shattered Horizon, some awesome zero-G combat happens is what.
Which company is going to call it Moon Base Alpha?
Aeiou

Heinlein wrote eloquently on the subject in more than one essay. ”The Moon Is a Harsh Mistress” being one, and “The Man Who Sold the Moon” another.
I am reading Daniel Suarez's Critical Mass right now, which is about a near-future mass industry getting bootstrapped on the moon after returning a bunch of raw materials from mining a nearby asteroid. Fun to see that reflected in actual news as I am reading fiction about the same thing!
(Sidenote: most of the tech is very realistic, but be aware the author has bought into blockchain hype, and you will be forced to read about how awesome DAOs are. But hey, maybe tech bros won't be allowed into space to ruin everything? not trying to be a total hater.)
Just can't see anything like this happening until there's not just workable fusion power generation, but portable versions of that technology.... which at this rate and given the challenges currently facing humanity, pretty doubtful that will ever occur. The costs of equipment delivery, resupply, material recovery and transport would be literally astronomical. There's just no way it makes money.
Why fusion ? A portable fission reactor could do the job.
What would we be mining for that could possibly necessitate and justify the costs of transport (equipment and materials) there and back? Almost any resource would be cheaper to mine on Earth, and the only exceptions would still be so rare as to require gigantic energy inputs.
The advantage to any space-based mining is not to directly benefit industry on Earth, but to help real manufacturing and other industrial scale operations in space. Doing that could lead to massive benefits for ground-based society, especially if we can automate so scaling to use resources beyond the Earth-Moon system became practical.
Sounds a little like starting a pot for chicken stock because you got an invite to an easter egg hunt.
@uphillbothways Couldn't it be a staging ground, not just for lunar mining, but also asteroid mining?
Maybe, but only if a lunar space elevator were built first. That could hypothetically be built with current technology.
Similarly, a terrestrial elevator to orbit would change things, but that requires further technological advancement.
Current propellant based escape technologies would prevent economic feasibility.
Helium-3; copious amounts in the lunar crust - but it's filtered out by our atmosphere.
https://en.wikipedia.org/wiki/Lunar_resources#Helium-3
"Materials on the Moon's surface contain helium-3 at concentrations estimated between 1.4 and 15 parts per billion (ppb) in sunlit areas,[1][61][62] and may contain concentrations as much as 50 ppb in permanently shadowed regions.[63] For comparison, helium-3 in the Earth's atmosphere occurs at 7.2 parts per trillion (ppt)."
Stretching the use of the word copious here... Helium 3 is specifically what I was thinking of when I said "the only exceptions would still be so rare as to require gigantic energy inputs."... Also, utilizing it would require fusion technology we don't have yet.
Listen, going to the moon and space travel is neat and all... There's just no way space mining makes money with current tech.
There are several institutes that differ from your opinion on abundance and profitability. There is an estimated millions of tons of helium-3 in the lunar surface at just a few meters down and it's estimated that just 25 tons would suffice to fuel the US power consumption for a year, and 200 ton for global needs.
Regardless of helium-3, establishing the infrastructure will allow for other mining as well. Platinum and other rare earth metals. Whoever does it first is going to make a butt load of money.
I hope so too. I just want to see some space faring progress in my lifetime. I missed the boat and am too dumb to contribute, but I can hope greed can bridge the gap where basic human progress fails to meet expansionist ideals. If it has to begin on the backs of investor money, at least it gets the ball rolling.
