Chinese engineers have unveiled a prototype device that could solve one of the biggest problems of long-duration space missions: dirty laundry. Specialists from the China Astronaut Research and Training Center have developed a “washing machine” prototype to help astronauts on orbit.
For astronauts working on space stations, dirty laundry has always been a significant issue. Due to the lack of washing machines and the scarcity of water, they wear clothes until they are completely soiled, and then they simply throw them away.
However, a new device, reported by the South China Morning Post (SCMP), could change this practice. The apparatus is capable of washing up to 800 grams of clothing using only 400 milliliters of water.
How the “Space” Washing Machine Works
The device’s operating principle is based on spraying clothing with a mist of tiny water droplets, followed by ozone treatment for disinfection. Hot air then dries the clothes and breaks down the ozone, while special sensors and filters prevent the release of harmful gases. Simulations have shown that the sterilization level reaches 99.9%.
The researchers plan to create a system that can last at least five years. In the future, they also aim to improve its efficiency for even longer missions. This device will allow astronauts to take 60% less clothing into orbit, significantly reducing the weight of the payload.
