Which, to me, seems like the closest real-world-on-Earth-world training simulation you could develop.
You’d be totally reliant on one power source, sealed inside a pressurized tube, with totally disrupted circadian rhythms. But at least on a nuclear sub, you have the chance to escape to the the surface world, and a chance to restock there. On Mars? Step outside, you’re dead, and if you can’t replicate a resource on a world with less gravity & less solar power & not a shred of a biosphere, you’re dead.
Sounds like a fun, low-stress environment to me. Humans do great with living with unrelenting psychological stress in sealed metal tubes.
The first realistic colonies should be at the bottom of canyons with glass ceilings. If they are big enough you won't even feel like you're stuck in a sealed metal tube.
