Astronauts assist push the frontiers of house exploration and nourishment, and now NASA has refined a water-recycling system that lets them drink their very own urine.

A vital life assist system on the International Space Station can recuperate 98% of the wastewater — which incorporates sweat and urine — that’s produced by NASA astronauts, in response to the federal house company.

Recycling meals, water and air is a crucial method of extending missions in house without having to make provide runs again to Earth.

One of the methods the Environmental Control and Life Support System produces drinkable water is by utilizing superior dehumidifiers that acquire moisture from the crew members’ breath and sweat. 

The trick for cleaning astronauts’ urine goes by a couple of extra steps.

The system first distills the urine, creating some water in addition to a urine brine. The brine is then filtered earlier than it’s blown with heat, dry air to evaporate the wastewater. That urine is handled once more by one other filter. 

The urine is examined and handled repeatedly till it reaches an appropriate ingesting customary. After that, the crews add a small dose of iodine to forestall any microbial progress. 

“The processing is fundamentally similar to some terrestrial water distribution systems, just done in microgravity,” Jill Williamson, the ECLSS water subsystem supervisor, stated in a launch. “The crew is not drinking urine; they are drinking water that has been reclaimed, filtered and cleaned such that it is cleaner than what we drink here on Earth. We have a lot of processes in place and a lot of ground testing to provide confidence that we are producing clean, potable water.”
