China's Space Station Achieves Full Oxygen Regeneration in Orbit

China's Tiangong Space Station has achieved 100% oxygen regeneration and 95% water recycling, reducing the need for ground supplies by six tonnes annually. The system has six subsystems for various operations, such as the creation of oxygen, the removal of carbon dioxide, and the creation of water from carbon dioxide and hydrogen. The technology is among the greatest in the world, according to Bian Qiang, director of the environmental control and life-support engineering office under the Astronaut Center of China.
