China Focus: China sets record for longest stay in self-contained moon lab

Volunteer Liu Hui prepares 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.
