Is it really necessary to send humans to those places just to get the knock-on benefits? Couldn’t we do those things directly, without going there?
It seems to me that, today, those who have the money to spend on these endeavors would only do so if there were perceived short-term benefits to themselves. That means they plan to exploit the resources, or increase their own power somehow.
I know the good engineers that make this happen are doing it for the challenge and in the pursuit of knowledge, and I know that’s why we poors support it, but that doesn’t “pay the bills.” What is the motivation behind the money? Why are they really doing this?
So I can’t speak to the actual motivation for the moon, but can for one reason for at-least-temporary human habitation there. Solar system exploration (and, inevitably resource extraction.
When you launch rockets from Earth, a vast majority of the fuel you start with is burnt off just getting to orbit, out of the deepest part of our gravity well. If you want to go anywhere else in our solar system, you’re severely limited to what’s left. The moon’s gravity is low enough that it could work as a refuelling station. Provided we find enough water there and set up solar hydrolysis stations there and build the infrastructure to get it up to orbiting ships. All that will take people to set up, and possibly to manage long term.
iirc it also has a lot of fusion fuel in the form of Helium-3
