Yuegong-1

Lunar Palace 1 or Moon Palace 1 or Yuegong-1 (Chinese: 月宫1号 or 月宫1 or 月宫一号 or 月宫一 ; pinyin: Yuègōng 1 hào or Yuègōng 1 or Yuègōng Yī hào or Yuègōng Yī) is a Chinese research facility for developing a moon base. It is an environmentally closed facility where occupants can simulate a long-duration self-contained mission with no outside inputs other than power/energy.

Lunar Palace 1, the 160m² 500m³ self-contained laboratory in Beijing, is composed of a 58m² vegetation area of two cabins, 42m² living area with 3 bedrooms, dining room, bathroom and waste disposal chamber. The lab was designed by Liu Hong of the Beijing University of Aeronautics and Astronautics (BUAA). The lab is a type of Bioregenerative life support system (BLSS), the third built in the world, and first in China.

With a crew of 3, 55% of the food consumed would be produced internally, the rest would be from stocks laid-in. The oxygen would be regenerated through the vegetation compartment. The water is recycled internally. The crew's waste was turned into fertilizer for the vegetation.

Construction on the facility began in March 2013. The facility was unveiled on Chinese New Year (31 January 2014). It was commissioned just prior to the first mission starting in February 2014.

The first research mission to use the facilities was the Integrative Experimental Facility "Lunar Palace 1" for Permanent Astrobase Life-support Artificial Closed Ecosystem (PALACE) Research (aka "Lunar Palace-1") 105-day mission of 3 researchers. The three, Dong Chen♂, Xie Beizhen♀, and Wang Minjuan♀, two women and one man volunteers from the BUAA, were the first multi-crew long duration research project undertaken of this kind in China, during the period 2014 February 3 to May 20.

The crew grew five cereals, including wheat, corn; soybeans, peanuts, lentils; 15 vegetables, including carrots, cucumbers, water spinach; one fruit, strawberries. The grown wheat provided the main source of calories for the crew and the primary source of oxygen. Meat was the primary laid-in foodstock; however, meat was grown on the mission as well, in the form of yellow mealworms, the primary protein source for the crew.
