WATCH: This is how astronauts use the toilet in the International Space Station BY Alejandro Alba NEW YORK DAILY NEWS Sunday, May 10, 2015, 7:28 PM Have you ever wondered how and where astronauts got to the restroom? Well, wonder no more. Samantha Cristoforetti, the Italian European Space Agency astronaut, explained the use of the space toilet in a YouTube video the ESA uploaded Friday. When nature calls, astronauts aboard the International Space Station go through a two-step process that involves a small receptacle, a rubber suction hose and a urine recycling unit. Cristoforetti explained that when they have to pee they go to the ISS toilet cabin and pee into the rubber hose that uses suction to collect urine—which is very helpful considering everything floats in weightless conditions. ESA via Facebook Astronaut Samantha Cristoforetti conducts a tour of a bathroom facility on the International Space Station. Once the hose collects the urine it is transported to the urine processing assembly (UPA) and it is recycled into drinkable water. When it comes to taking a space dump, Cristoforetti said it works in a similar way. There is also a suctioning hose, but the feces is stored in a waste tank that it changed once every 10 days depending on the size of the onboard crew.
