, the desert-dwelling Fremen of the arid planet Arrakis recycle their body’s moisture using specially designed outfits called stillsuits. Inspired by such imaginings,Frontiers in Space Technologyseries for as long as I can remember,” says Sofia Etlin, a space medicine and policy researcher at Cornell University. “Building a real life stillsuit was always a bit of a dream.
A fictional Fremen’s stillsuit is powered by body movement, but astronauts will have to carry a 20.5-volt battery as part of this new design. The total system, including pumps, sensors and display screen, weighs around 8 kilograms and can purify half a liter of water in five minutes. The team hopes to further test its system during simulated moon and Mars missions here on Earth and eventually during real spacewalks.
