Everyday operations in orbit: toilet maintenance
In this timelapse, ESA astronaut Sophie Adenot performs routine maintenance on the Waste and Hygiene Compartment, or WHC – the ISS toilet system. She is replacing the full solid-waste container in which solid waste is vacuum-dried, compressed and kept airtight. This operation typically takes place once or twice a week, when the container reaches capacity.
