“Laundry is even easier — much like your college dorm years, we don’t even bother doing it. A good pair of jeans will last for six months in space, and I wore the same socks and underwear for four days straight (I tried to continue doing this on Earth in the name of science, but my wife objected). That’s because our clothes aren’t actually touching us — they’re floating away from our bodies, meaning they’re not pressed against our skin, soaking up all the funk. That’s not something you’d ever think of, but it makes perfect sense as soon as you experience it.
If you need a haircut, just ask a colleague to grab the hair clippers, which are connected to a vacuum tube. As a general rule, most astronauts don’t have any salon experience, but we’re more about function over fashion. Trimming my mustache was trickier and required the use of an actual vacuum cleaner, but I’m always careful when trimming it anyway, as it is the source of my power.”
