NEW YORK, July 20: Scientists have developed a promising new technology that could significantly improve the experience of astronauts on spacewalks by recycling urine into drinkable water within minutes. This innovation comes as a response to the challenges astronauts face during extended spacewalks outside the International Space Station (ISS).

For years, astronauts have used a maximum absorbency garment (MAG) — a high-tech diaper designed in the 1980s — to manage bodily functions during spacewalks. While effective in collecting urine, MAGs do not recycle the water and can cause discomfort and potential skin issues during long missions, which can last up to eight hours. Astronauts also have to rely on a limited supply of water carried in an in-suit drink bag.

The newly developed system aims to address these issues by introducing a lightweight, efficient method to recycle urine. This system involves astronauts wearing an undergarment made from flexible compression material and antimicrobial fabric. Equipped with a humidity sensor located within a silicone cup beneath the wearer's genitalia, the system detects urine and activates a vacuum pump.

The pump draws the urine into a filtration device attached to the astronaut's back. Measuring approximately 15 inches tall and 9 inches wide, the 17.6-pound filtration device processes the urine, converting it into fresh water that can be delivered to the spacesuit’s drink bag. The entire process takes about five minutes, allowing astronauts to stay hydrated without carrying additional water.

Currently in the testing phase, this new technology represents a significant advancement in space exploration. If successful, it could address the logistical challenges of managing waste during spacewalks, particularly as NASA plans to establish a permanent lunar outpost by the end of the decade.

The system’s development highlights ongoing efforts to improve the comfort and efficiency of astronauts' missions, marking a potential breakthrough in space travel and sustainability.
