Access to fresh water can be a problem in space. American astronauts at the International Space Station (ISS) get most of their water by recycling and recovering it using the Water Recovery System, which NASA introduced in 2009.
Just as the name implies, the Water Recovery System allows astronauts to recover most of the water they lose through sweat and urine or while brushing or making coffee.
American astronauts aren’t just recycling their own urine.
They’re also recycling the urine of cosmonauts, since the Russians have refused to recycle their own pee. According to Layne Carter, NASA’s water subsystem manager for the ISS, the recycled water tastes just like bottled water.
