The 180 days experiment with 4 volunters was started in June, 2016, and will finish in December. It is examined how oxygen, water and food can be used and reused in space. The physiological changes and emotional fluctuations of the volunteers brought by a hermetic environment will be checked, and a total of 25 kinds of plants in the capsule are studied as part of a larger ecological treatment system.
