Brief introduction of space farm

Space Farm, whose scientific name is Controlled Ecological Life Support System (CELSS), solves the supply problem of the most basic materials such as food, oxygen and water needed by astronauts by cultivating green plants (vegetables, algae, etc.). In space, this is one of the key technologies and problems to realize long-term manned interstellar travel and immigration in the future. In the future space program, the United States will list "long-term experiments of plants in a sealed space capsule" as a key research project. In order to realize the grand plan of returning to the moon in 20 18 and manned landing on Mars in 2033, the space farm of the other three research centers of NASA, some military enterprises, research institutes, universities and research centers are in full swing.
