I was having a chat with my Mum the other day and, somehow, the subject of ISS housekeeping came up.
Now, I am sure that there are plenty of filters in the air circulation system on the ISS but it is still a sealed box floating in space! No possibility of opening a window for a bit of ventilation (as it were). Skin scales, hair, sweat, snot (and even worse things ) are going to be floating around inside and accumulating in all sorts of nooks and crannies (Like the filth that accumulates on the inside of a PC after a few years)
How DO they keep the place fit do live in?
Or don't they bother! (I understand MIR was pretty rank during its final years)
Oh, and while we are at it, My Mum would also like to know how they clean the inside of spacesuits (as would I)?
All this sounds a bit trivial, but I can imagine it would be a pretty big issue on, say, a Manned Mars Mission!
Floating-in-space is due to under-powered faulty space tech regime we live under.
I'm not going to ignore the physics of gravity.
But there are other classical physics techniques which can be employ to make life more bearable and sanitary such as angular momentum the 'carnival ride'. But these techniques require more power than can be delivered in space in part due to restrictions on nuclear power use in space.
Some deficiencies in space technology are purely due to bad policy and politics.
