Researchers at Cornell University have designed a novel in-suit urine collection and filtration system, or “Dune” system,” to “promote astronaut wellbeing.”
A marvel of the “Dune” sci-fi film franchise is the survival outfit worn by the desert-dwelling Fremen — “stillsuits” that recycle all bodily fluids into potable water. Now, such technology appears to be on the horizon, with scientists unveiling a prototype spacesuit system that turns urine into drinking water. Astronauts can spend a considerable amount of time outside their space habitat doing extra-vehicular activities, or EVAs.
Astronauts have said the current amount of water it provides is not enough. ‘Dune’ system To “promote astronaut wellbeing,” the researchers have designed a novel in-suit urine collection and filtration system, or “Dune” system,” Etlin said. The system would recycle urine using forward and reverse osmosis, a model used by the current wastewater management treatment system aboard the space station, to remove contaminants from the urine and filter it to drinking water.
