When astronauts go on a spacewalk, their urine is collected by what is essentially a large diaper before being thrown away, and they have less than a litre of drinking water available - but a new kind of spacesuit could solve both issues
Astronauts on spacewalks may soon be able to drink their own urine, thanks to a water filtration and recycling system that could be ready in time for NASA’s upcoming crewed missions to the moon.
The purified water is then ready to drink and can be piped into an in-suit bag. This has the additional benefit of ensuring a steady supply of drinking water: the current NASA spacesuits provide just under a single litre of drinking water, which is often insufficient for a long spacewalk. The remaining 13 per cent of the water content cannot be extracted and remains in the filter.
