>>6 Completely agree - the only real issue we'd run into would be political, as we don't own the moon, and the bureaucracy behind claiming such a thing over other countries would be ridiculous, and potentially conflict-inducing if taken lightly.
I have to question the part about the gravitational force, though. We won't be mining an incredible amount out of the moon, though it's true we run that risk of tipping the balance just enough to fuck up its orbit. However, if this were ever taken up as a large-scale project, I'm sure this is one of the first things astrophysicists would yell at them about, so it's likely not a problem.
The only problem regarding that would stem from mass hysteria due to uninformed majority opinion that our scientists don't take into account these simple mistakes. I mean, even
I can think of a solution to that if they're really worried - bring a lot of dirt with you, and replace it :|
It's a dumb solution, but a solution nonetheless. Point being, if I could come up with that, the professionals would be able to do one even better.
In terms of mining it as well, gravity has little to do with it. They'll be mining it by machinery - that much I'm sure you already get. Most likely, they'll build the machinery when they get there, so bringing up parts really isn't a big deal if they ever get the funding necessary to pull off such a stunt.
And it isn't 0 gravity, just low gravity.
I'm curious about the H3 comment you made though. What do you mean, inevitable end? I hope that isn't something against nuclear technology; I'm probably reading into it too much.
If wikipedia is anything to go off of (it hasn't failed me yet), the scientific community is actually very much interested in mining H3 from not only the moon, but other planets and gas giants. The issue is the same with mining the moon though - politics, funding, etc. In addition, H3 is scarce even on the moon - the moon just has a larger amount of that scarce molecule.
If anything, the reason it was deemed not worthy of their time and effort was because of this. The amount of resource it takes to fly up to the moon in the first place greatly outweighs what they would potentially receive from such an endeavor.
"Cosmochemist and geochemist Ouyang Ziyuan from the Chinese Academy of Sciences ... has already stated on many occasions that one of the main goals of the program would be the mining of helium-3, from which operation "each year three space shuttle missions could bring enough fuel for all human beings across the world." which is an
extreme overstatement however, as one payload to GTO of current spacecraft designs is less than 4 tonnes. To "bring enough fuel for all human beings across the world",
more than one Space Shuttle load (and the processing of 4 million tons of regolith) per week would be necessary."
