I'd look at a house on earth and ask: what things have to be supplied from the outside; what things can be produced inside the house? Houses on earth have piping for water, and cabling for electricity.

Plants can be grown in a green-house using these two ingredients, and the people can sleep in a spaceship.

Comment whatever comes to your mind.

Off the top of my head, you could get some solar power with a massive array. It’s possible to generate oxygen from the Martian atmosphere, as NASA recently proved.

I would think any permanent structure on Mars is going to be more like the ISS except underground. So, basically everything will have to be resupplied from Eart. There could be some in-situ resource utilization but it’d be challenging.

I think that water is an important resource. Once that you have water and electricity, you can produce oxygen easily. And you need large quantities of water anyways.
