the iss is regularly supplied with air, prepackaged-food, water and toilet paper. a trip to mars isn't going to be, dummy. apollo only had to work for days and only the air was scrubbed, poorly. you are being intellectually dishonest. > "...humans can't even make a washing what can run non-stop for months on end and you're telling me these men have to rely on a machine that's keeping them alive and not contaminating their food with their own piss and feces reliably for months? give me a fucking break." the iss has no self-contained closed-loop life-support system. you're deluded if you think nasa has one.
