Scientists are working on a spacesuit that will transform urine into drinkable water
Boffins at Cornell University have created a prototype outfit akin to ‘Dune’s Stillsuit that features a device that recycles 87 per cent of waste into sanitised drinking water in five minutes.
In a recent study published in the journal ‘Frontiers in Space Technology’, author Sofia Etlin said: “The design includes a vacuum-based external catheter leading to a combined forward-reverse osmosis unit, providing a continuous supply of potable water with multiple safety mechanisms to ensure astronaut wellbeing.”
Currently, astronauts that embark on lengthy spacewalks have to wear nappy-like undergarments called maximum absorbency garments (MAGs), which allows them to relieve themself on the go.
However, scientists want to move away from this method due to health risks these contraptions pose toward astronauts.
Etlin explained: “The MAG has reportedly leaked and caused health issues such as urinary tract infections and gastrointestinal distress. Additionally, astronauts currently have only one liter of water available in their in-suit drink bags.
“This is insufficient for the planned, longer-lasting lunar spacewalks, which can last ten hours, and even up to 24 hours in an emergency.”
