Liquid Lifeline: NASA Tech Could Create IV Fluid In Space

On every crewed mission, NASA packs pouches of a potentially life-saving liquid in its cargo, known as IV (or intravenous) fluid. A simple mix of sodium chloride and purified water, it can treat up to 30% of medical conditions in flight, resolving things like dehydration, burns, and more. Crewed missions beyond low Earth orbit into […]
