If humans ever want to work and live in space, whether in habitats on the Moon or Mars or in stations far from Earth, a reliable source of clean drinking water is essential. This presents many challenges in space, where resources are limited, and resupply missions are costly, time-consuming, or both. For starters, humans cannot survive for more than three days without water. Water is also essential for oxygen generation, irrigating edible plants, and hygiene. Meeting these requirements requires a closed-loop system that can provide clean water for months to years without replenishment.
