🎶🇺🇸CRAWLIN BACK TO YOOOOOUU🇨🇳🎵

Afraid I gotta be a killjoy here; we're not gonna see a colony on the moon (or any other celestial body) at any point this century. To make a long-term habitable settlement, you'd need to either foster an ecosystem from scratch, or use industrial processes to supplement all the biochemicals and compounds and stuff needed to keep a person alive. The former would be very difficult. It would take (at the very least) decades of experimental ecological husbandry just to figure out how to start.

The latter is just flat out beyond anybody's industrial capacity - like, orders of magnitude beyond. Everything we produce and enjoy today as industrialized societies is supplemental. A rounding error. The manufacture and processing of the countless things needed to be alive, all that biochemical work is done by every living thing in the ecosystem. We have only a dim understanding of the processes behind the things we know we need, and there's certainly more we have yet to notice.
