In a leap toward sustainable space living, the China Astronaut Research and Training Center—under the China Manned Space Agency (CMSA)—has introduced a groundbreaking washing machine designed specifically for space missions. Compact, efficient, and detergent-free, this innovation could reshape how astronauts manage hygiene during long-duration flights.

🚀 Smart Cleaning in Microgravity

The cube-shaped device, slightly larger than a carry-on suitcase and weighing just 12 kg, uses only 400 mL of water per cycle to clean up to 800 g of clothing. Instead of traditional detergent, it relies on a fine mist and ozone—a powerful oxidizing agent—to eliminate bacteria and odors. After use, the ozone safely breaks down into oxygen, minimizing environmental impact.

💧 Why It Matters

Water is one of the most precious resources in space. On the International Space Station (ISS), astronauts recycle up to 90% of their water—including sweat and even urine—for drinking and hygiene. NASA aims to push that figure beyond 95% in future missions. By reducing water usage and eliminating the need for detergent, China’s ozone-based washer supports this goal while cutting down the mass of clothing needed for long-term missions.

🌍 Beyond Space: Earthly Implications

While designed for orbit, this tech could inspire ultra-efficient laundry solutions here on Earth—especially in regions facing water scarcity. As space agencies race to make deep-space travel more sustainable, innovations like this are proving that even dirty laundry can spark clean ideas.
