Given how filthy the ISS is, I don't know if I'd want to eat anything not nuked into oblivion.
Why would it be filthy? It's not like they get a lot of dirt out there
Dust comes from human skin flakes.
There a giant vacuum though.
Just open two opposite windows.
Well that didn't work (windows outlook debacle).
Part of it yes, but I'd assume they also clean there sometimes.
Part of it is I don't know how skin particles will act inside a space station. Are there static electricity forces that would make it stick to surfaces, or does it remain suspended in air until the filtration gets to it?
Static electricity would definitely be a factor, but there’s probably pretty good air circulation and filtering. That combined with regular wipe downs of surfaces probably keeps dust under control.
I know the moon missions in the past had a hell of a time dealing with lunar dust. It’s super fine and static was sticking it to everything.
Imagine trying to clean it. You can't whip out a mop. Showers, wash cycles etc are all no go. Not too mention experiments from plants, chemicals, drugs etc which create their own issues. In some ways it's clean, but others not so much.
You can use a vacuum cleaner, but since there's hardly any gravity most would already get picked up be a simple air filter.
