Aaah! Space travel sounds much fun!!! You could say it's a lot like being in the army :P
Urine filtration? I remember reading another post on toilet water filtration in order to make it safe for consumption. The idea is kind of disturbing, but if everything works according to plan and the process is successful and the water comes out clean and safe to drink, then I guess it will be ok (?)
Yes, I think the filtration and processing is very very good. It's just the thought the it was pee just yesterday.
At least here on Earth the water we drink has likely evaporated and rained down several times before making it to our faucets.
