ESA wants to make astronauts’ shared spacesuit underwear more hygienic
Yes, it’s true — astronauts share ‘underwear’ when they put on spacesuits to work outside of the International Space Station. This isn’t quite the same type of underwear you’re thinking of, as the astronauts first put on a disposable diaper, then the full-body underwear layer. Still, there are some downsides to this arrangement that the ESA is attempting to address with a new project.
