The new toilet, the universal waste management system (uwms), weighs only 45 kg (100 lb) and is 71 cm tall. It is 65% smaller and 40% lighter than the toilets currently used on the international space station.
For many people, how astronauts go to the toilet in space is an old problem. Going to the toilet in space may sound simple, but in weightlessness, this simple thing can become very difficult.
In addition to womens consideration, the versatility of the new toilet is also key. Its core design concept is that the toilet can be easily integrated into various spacecraft and life support systems.
NASA said that in places like the international space station, where astronauts live and work for a long time, uwms will convert the pretreated urine into a regeneration system for further use. For shorter tasks, uwms works with another system, where waste is stored without chemical pretreatment.
NASA astronaut Jessica Meir said 90 percent of the water-based fluids on the space station, including urine and sweat, we tried to mimic the elements of the earths natural water cycle on the space station..
