Analog suit life support
From OpenLuna
Air - A non-space qualified Narked at 90 rebreather, but using cheaper CO2 scrubbers and pressurized O2. (Or so I think.) The breathing bag and control electronics should be the same, and the fail-safe "limp home" mode should still work the same.
Water - Water extraction from air should work the same, urine recycling, at some point, but not in early suits. Water supply in the suit should remain the same.
Waste - Storage in later suits.
Food - Later suits? As early as we can.
