TOKYO: Italian astronaut Samantha Cristoforetti sheds some light on one of the more mysterious aspects of space travel: How do astronauts answer the call of nature aboard the International Space Station in zero-gravity conditions?
Inside the ISS toilet cabin, Cristoforetti explains the two-step process for going to the bathroom. Taking a pee demands the use of a rubber hose, which contains a switch that activates a suction to collect the urine.
Such a device is essential aboard the ISS, where anything and everything floats in weightless conditions.
