Summary:
-
Researchers from Cornell University developed a spacesuit urine collection and filtration system inspired by the ‘stillsuits’ from the Dune franchise, designed for hygiene and comfort during long spacewalks.
-
The system recycles urine into potable water using a vacuum-based external catheter and a forward-reverse osmosis unit, achieving an 87% recycling efficiency.
-
The compact and lightweight system, weighing approximately 8 kg, will be tested in simulated conditions and future NASA missions to the moon and Mars.
