Researchers Examine How We Could Achieve Sustainable Water Systems for Space

If humans want to live in space, whether on spacecraft or the surface of Mars, one of the first problems to solve is that of water for drinking, hygiene, and life-sustaining plants. Even bringing water to the International Space Station (ISS) in low Earth orbit costs on the order of tens of thousands of dollars. Thus, finding efficient, durable, and trustworthy ways to source and reuse water in space is a clear necessity for long-term habitation there.
