Astronauts on board the International Space Station have produced water by collecting moisture and distilling urine, marking a huge advance for space travel.The team used the Environmental Control and Life Support System (ECLSS) of the space station to reach this milestone.

The waste water collection system is made to gather sweat and breath moisture and send it to the Water Processor Assembly (WPA), which turns it into drinkable water. The Urine Processor Assembly (UPA) also uses vacuum distillation to recover water from urine.

However, the urine brine produced by this distillation process still contains some water molecules. To further extract water from the brine, researchers have been testing a novel technique called the Brine Processor Assembly (BPA). Wastewater extraction system known as the BPA is being evaluated in a zero-gravity environment.

It uses specialised membrane technology to treat the brine made by the UPA before blowing warm, dry air over it to evaporate the water. The station’s water collecting devices capture the humid air that is produced as well as personnel breath and sweat. The water created by this procedure, according to scientists, is cleaner than the water we drink on Earth.

He clarified that the crew is not drinking urine directly but rather consuming reclaimed, filtered, and thoroughly cleaned water.
