The Moon contains rich reserves of water, rare-Earth metals, and helium-3
Our Moon is more than just some pretty decoration for the night sky and a place to plant a few flags – it’s also a potential source of valuable raw materials that could someday be used for energy and engineering both on Earth and in space.
If you saw the movie Moon (and if you haven’t I highly recommend it) there was a whole lunar base set up for the extraction of helium-3 from the surface. This isn’t some fantasy “unobtainium” element, it’s a very real isotope that’s rare on our magnetically-shielded Earth but common on the Moon, where it can be easily deposited by the solar wind. Helium-3 alone could make lunar mining ventures economically (or at least environmentally) sensible as it could theoretically power nuclear fusion reactors on Earth with virtually no radioactive waste products.
