A Chinese research team has unveiled a prototype washing machine designed for use in space, joining a growing international push to solve one of the more mundane but pressing challenges of long-duration missions: laundry.
China Says No to Smelly Astronauts - Space Washing Machine in the Works
Currently, astronauts aboard the International Space Station (ISS) and China’s Tiangong space station cannot wash their clothes. Instead, they wear garments multiple times before discarding them, adding significantly to cargo loads on resupply missions. As China plans for extended stays aboard Tiangong and prepares for future lunar and Mars missions, the need for a sustainable clothing-cleaning system has become more urgent.
The Chinese design reportedly uses minimal water and detergent, relying on condensation recycling and vibration technology to loosen dirt and sterilize fabrics. Engineers say the system must balance three demands:- low water consumption, efficient power use, and the ability to operate in microgravity without spilling or causing vibrations that could disrupt the spacecraft.
The project places China alongside other players in the space laundry race. Last year, NASA and Procter & Gamble announced joint trials of Tide’s special detergent and cleaning system for space use. Meanwhile, European researchers have tested concepts such as ultrasonic cleaning and fabric-recycling solutions.
Space experts note that while a washing machine may sound like a trivial luxury, it could have major benefits. Clean clothes reduce health risks and improve morale on months-long missions. They also cut down on the need to send large volumes of fresh garments from Earth, freeing up cargo space for food, equipment, and scientific instruments.
As China accelerates its space program - with plans for a lunar base by 2030 - developing practical technologies for everyday life in orbit is becoming increasingly central. The new washing machine prototype is expected to undergo further testing before potential deployment on Tiangong.
“Living in space isn’t just about surviving, it’s about sustaining a healthy, comfortable environment,” one researcher was quoted as saying. “A washing machine may seem simple on Earth, but in space it represents a big step toward long-term human presence.”
