Astronauts aboard the International Space Station have achieved a 98% water recovery rate in a breakthrough achieved by a method that might make the faint of heart slightly squeamish: they hit peak astronaut pee recycling.
The water recycling achievement is an important milestone for low-orbit space missions that aim to provide the basic needs of astronauts without resupply missions. This means recycling or regenerating things like food, air and water.
This has the potential to be a useful technology for some places on earth too. Would help reduce issues desert cities have with water, say.
