NASA just recycled 98% of all astronaut pee and sweat on the ISS (engineers are thrilled)

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.
