Long-Duration Life Support
On the Space Station, water and air can be topped up from Earth; on a multi-year voyage to Mars there is no resupply. Life support must therefore recycle almost everything — reclaiming water from every source and regenerating oxygen — and may ultimately grow food, closing the loop far more tightly than any system flown so far.
