Re: This is at least practical
"On the Moon if something goes wrong they can't fix, so long as it didn't go catastrophically wrong help is only a few days away. "
The mission currently in place would have the ride home in a week long lunar orbit. If the landing system requires over 20 refueling flights to put down one lander, that's weeks before emergency supplies or personnel can be sent.
Talk of nuclear power is guessing about something way off in the future. So far there's only some talks about preliminary designs that would still need to be adapted, prototyped, tested and approved. That's not going to happen in a month or 12. Solar panels are rather simple. A lander that unfolds an array like a flower opening up could be designed and built in a short amount of time. Every battery on every craft can be specified so it can be used for storage of solar power so as time goes by, a station would have more capability. It would have made things easier on Apollo 13 if the CO2 scrubber cartridges were the same on the capsule and lander.
The US has put people on the moon. If they stick with what is known to have worked as a mission design, boots could be on the ground in a few years. What's being "planned" now is massively complicated and the focus has been on getting there, not back nor establishing any sort of village. The south pole as a target is also highly aggressive with lots of risks. Maybe there's water resources or maybe there's only some frost. There could be lots of water, but locked up in regolith that will take lots of processing to extract it.
