How do astronauts wash clothes in space? They don’t wash it.
They wear their underwear, gym clothes, and everything else so they can’t take dirt and odor and then destroy it.
NASA wants to change that — if not in season, then at least on the Moon and on Mars — and stop throwing away tons of dirty laundry every year, Put them in the trash for burning in the abandoned warehouses. So he’s collaborating with Procter & Gamble to determine the best way to clean astronauts’ clothes in space so they can be reused for months and even years, just like on Earth.
Cincinnati announced Tuesday that it will send into space this year and next a pair of experiments with Tide detergentTo try to solve the problem of dirty and sweaty clothes.
It is not a minor problem, when the United States and other countries plan to establish bases on the Moon and on Mars.
Rocket cargo space is cheap and expensive, according to NASA, so there’s no point wasting it on new clothes if the clothes you have can be kept new. If you calculate that an astronaut needs 150 pounds of clothing in space each year, that adds up quickly, especially on a three-year mission to Mars, said Mark Civic, a chemist who specializes in tissue technology and world care. .
In addition, there is health factors.
Station astronauts exercise for two hours each day to combat the effects of weightlessness on muscles and bones, which quickly leave their exercise equipment sweaty, smelly, and stiff. Their shirts and socks smell so bad that they only wear one pair a week, according to Lilan Melvin, a former NSASA astronaut and former NFL player.
“After that time, these materials are considered toxic,” said Melvin, a project spokesperson. “It is as if they have their own lives. They are cruel of every race.”
In its initial trial, P&G will ship in December A cleaner designed specifically for space So scientists can figure out how enzymes and other ingredients interact with six months of weightlessness. Then, in May, the anti-stain wipes will be sent to the station for astronauts to test.
