Sustainable water recycling for long‑duration space habitats Water for drinking, hygiene and plant growth is a primary constraint on long‑duration human spaceflight: resupplying the ISS costs on the order of tens of thousands of dollars per delivered mass. Durable, efficient closed‑loop water sourcing and reuse are essential to enable months‑to‑years surface and orbital habitation.
