NASA Recycles Astronaut Sweat and Pee into Drinkable Water on ISS
NASA's Environmental Control and Life Support System (ECLSS) on the International Space Station is now recycling 98% of all water astronauts bring onboard, including moisture from breaths and sweat, and urine through vacuum distillation. A new device can extract the remaining water in the urine brine, increasing the water recovery rate from 93 to 98%. NASA assures that the water is cleaner than what we drink on Earth.
