Achieving long-term manned flight in confined spaces, establishing and developing a life-health guarantee system for inter-satellite survival and suitable for long-term residence of multi-occupants is the primary problem that the world's space powers are committed to. At 11:15 on December 14th, with the participation of four volunteers who participated in the 180-day trial of the Greenway StarCraft for four people, the large-scale international trial of the first human and environmental field in China was a complete success. Li Yinghui, the person in charge of the test and deputy chief designer of the manned spaceflight system, said that the test deepened China's understanding of the third-generation aerospace environmental control and life support system technology and was an important engineering practice for developing the technology. As the test reaches its intended goal, it opens up a new situation for the advance research of the life support technology of the extraterrestrial base, and also provides an important technical basis for the follow-up experimental research and the mission of China's space station. It is reported that Greenway StarCraft is the controlled ecological life insurance test with the longest time, the largest number of people and the highest system complexity in the world. Turn Mars Seeds into Reality As humans continue to explore deep space, the plot of Mars planting potatoes in the movie will sooner or later become a reality. This test is a forward-looking construction of an extraterrestrial planet base, with the primary goal of solving human survival and health problems. Li Yinghui introduced that aerospace environmental control technology can be divided into three generations. The oxygen, water, food and other materials of the first generation of technology are all carried from the ground, and the waste is not recycled. It is mainly used for short-term missions and is used in Shenzhou spacecraft. The second generation technology is based on physical and chemical regeneration, which can realize the regeneration cycle of air and water, but the food still needs ground supply. It is aimed at medium and long-term missions, for the International Space Station and the future space station in China. The third generation technology is based on the principle of ecology, organically blending the first two generations of technology, artificially establishing a closed and controlled ecosystem, and coordinating multiple functional units such as animal and plant cultivation, wastewater waste treatment, and atmospheric regulation to achieve food in a closed environmental system. High-efficiency recycling of the atmosphere and water to significantly reduce the demand for material replenishment for space missions. This test is the beginning of the third generation of environmentally-controlled biocontrol technology research. Yu Qingni, the head of the test technology and deputy director of the Center for Environmental Management of the Astronaut Center, said that most of the self-sufficiency required for life was achieved in the trial, including 100% oxygen, 99% water and 70% food.
