Chinese may grow veggies on the Moon
Chinese taikonauts may get fresh vegetables and oxygen supplies by gardening in extraterrestrial bases in the future, an official said after a just-concluded lab experiment in Beijing.
Deng Yibing, Deputy Director of the Beijing-based Chinese Astronaut Research and Training Center, said that the recent experiment focused on a dynamic balanced mechanism of oxygen, carbon dioxide and water between people and plants in a closed system.
According to Deng, a cabin of 300 cubic meters was established to provide sustainable supplies of air, water and food for two participants during the experiment. Four kinds of vegetables were grown, taking in carbon dioxide and providing oxygen for the two people living in the cabin. They could also harvest fresh vegetables for meals, Deng told Xinhau.
The cabin, a controlled ecological life support system (CELSS) built in 2011, is a model of China's third generation of astronauts' life support systems, which is expected to be used in extraterrestrial bases on the Moon or Mars.
