Just because things are weightless in space doesn’t mean astronauts can bring whatever they want on their flights. Since they must ensure that the takeoff masses are as low as possible, they must travel light. Very light.

This means that the number of personal items should be kept to a minimum, including the number of underwear changes. No seriously. They should wear each pair for as long as possible, even if they have to train two hours a day according to regulations.

According to the Associated Press, an astronaut needs 68 kilograms of clothing in space per year. If they eventually leave for a six-month stay on the International Space Station or a three-year Mars mission, with current options, baggage and storage limits would not allow for many changes of clothing.

And anyway, there is no place to do laundry. So what’s a high thief to do? Well, wear the stuff until they are too disgusted with themselves to last another day, then carefully fold the item into an unmanned cargo capsule that will be dropped to burn in the atmosphere at his return to Earth.

Being an astronaut may seem glamorous and coveted, but in reality, much of everyday life is a chore. Basically, t-shirts, underwear and socks end up getting so dirty that crew members go through a pair every week, former NASA astronaut and player Leland Melvin told the AP. of the NFL.

“After that, they are deemed toxic,” said Melvin, spokesperson for the project. “They, like, have a life of their own. They are so stiff from all this sweat.

In an effort to alleviate the overall problem, Procter & Gamble will send two Tide detergent and stain removal experiments to the ISS later this year and next year.

in December, P&G will launch a tailor-made detergent for the space; Scientists at the ISS will study how enzymes and other ingredients react to six months of weightlessness.

Then, in May, astronauts will receive stain remover pens and wipes for testing.

And while NASA or another space agency sets up a colony on a celestial body, P&G says it’s developing an eco-friendly washer-dryer combo that will use minimal amounts of water and detergent. Such a machine could also prove useful in water-problem areas here on Earth, AP suggests.

One of the many challenges with capsule design, however, is that lye water must be collected for drinking and cooking. But given that urine and sweat are recycled aboard the ISS, the reuse of gray water doesn’t seem overwhelming.
