ESA astronaut Samantha Cristoforetti shows how to use the most unglamorous but often asked-about part of living on the International Space Station: the toilet.
A fan creates suction to avoid smells and floating waste. Solid waste is stored and put in cargo ferries to burn up when the spacecraft leaves the Space Station. The astronaut urine is recycled – into drinking water.
