Volunteers prepare to leave the Yuegong-1, or Lunar Palace 1, at Beihang University in Beijing, capital of China, May 15, 2018. Chinese volunteers have completed a one-year test living in a simulated space lab in Beijing, setting a new record for the longest stay in a self-contained cabin. The total length of the test, which started on May 10th last year, reached 370 days, with the third stage accounting for 110 days. Liu Hong, chief designer of Yuegong-1, said the test marks the longest stay in a bioregenerative life support system (BLSS), in which humans, animals, plants and microorganisms co-exist in a closed environment, simulating a lunar base.

The BLSS can also be applied in areas where water is scarce and oxygen levels are low, he said.

The previous record was set in the Soviet Union, where three people stayed for 180 days in a similar closed ecosystem in the early 1970s.

FULL RECYCLING

The cabin consists of two plant cabins and a comprehensive cabin. The volunteers grow wheat, strawberries and other plants. There is small amount of pre-stored pork and chicken. The main vitamin source for the volunteers are yellow meal worms raised in the cabin. They are roasted, ground and mixed with flour to make buns and pancakes.
