href=\"https:\/\/www.sciencenews.org\/article\/book-review-spacesuit-fashioning-apollo-nicholas-de-monchaux\">suited up in space<\/a>, astronauts currently relieve themselves into what\u2019s known as a maximum absorbency garment, which is essentially a multilayered diaper containing a super-absorbent polymer (<em>SN: 3\/11\/11<\/em>). The garment is known to be uncomfortable, leak and cause urinary tract infections.<\/p>\n\n\n\n<p>Current spacesuit designs also incorporate an in-suit drinking bag, or IDB, that carries less than a liter of water. Astronauts can sometimes go for eight- to 12-hour spacewalks, which often includes enormous amounts of physical exertion, Etlin says. NASA\u2019s <a href=\"https:\/\/www.sciencenews.org\/article\/artemis-mission-new-diverse-crew-astronauts-moon\">future Artemis missions<\/a> on the moon will probably see explorers spending at least as much time or longer on the lunar surface, though current plans have them carrying IDBs of the same size, she says (<em>SN: 12\/1\/22<\/em>).<\/p>\n\n\n\n<p>Etlin and her colleagues designed and built a new type of undergarment with a collection cup that goes over an astronaut\u2019s private parts. Urine is routed into a filtration system that first removes salty water from the urine and then uses a pump to take the salt out from that water. The filtered water is enriched with electrolytes and then sent into the IDB.<\/p>\n\n\n\n<p>A fictional Fremen\u2019s 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.<\/p>\n\n\n\n<p>Sweat \u2014 which fictional stillsuits also collect \u2014 would be easier to filter than urine, Etlin says. But she and her colleagues decided to focus on a single waste product for their first prototype. \u201cOne step at a time,\u201d she says.<\/p>\n\n\n\n<p>The team hopes to further test its system during simulated moon and Mars missions here on Earth and eventually during real spacewalks. <\/p>\n\n\n\n<p>It \u201cwould be amazing for us,\u201d says Julio Rezende of the Federal University of Rio Grande do Norte in Natal, Brazil, who leads Habitat Marte, a Mars analog mission in Brazil. \u201cI believe this technology would bring a lot of benefits.\u201d<\/p>\n\n\n\n<p>Rezende sees potential terrestrial spin-offs, too, such as a similar system that could be used for firefighters combating forest fires or hikers on long trails.<\/p>\n\n\n\n\t\t\t<\/div>\r\n<br>\r\n<br><a href=\"https:\/\/www.sciencenews.org\/article\/dune-spacesuit-astronaut-pee-water\">Source link <\/a>","protected":false},"excerpt":{"rendered":"<p>In the science-fiction series Dune, the desert-dwelling Fremen of the arid planet Arrakis recycle their body\u2019s moisture using specially designed outfits called stillsuits.
