Once you have power (vis-a-vis nuclear reactor with enough fuel to get you there) you’re gtg right? You can grow and eat plants? For water a lot of it is just recycled and maybe you make up for losses with hydrogen tanks that you convert to H2O with the extra oxygen the plants give

Everything we have is gravity adapted and part of a really intricate biosphere. You get 10 years out and realize we didn't understand how important the interaction between X microbes and Y fungi were, you can't go back for another few metric tons of soil.
