Yuegong-1

Lunar Palace 1[1] or Moon Palace 1[2] or Yuegong-1[3] (Chinese: 月宮1号[4] or 月宮1 or 月宮一号[5] or 月宮一 ; 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.

Facilities

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.[1][2][6]

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.[1][7]

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.[3][6]

Missions

Integrative Experimental Facility for Permanent Astrobase Life-support Artificial Closed Ecosystem Research

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.[1][6]

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.[1][6]

The diet studied was to determine if a spacecrew could subsist on a high protein diet with vegetation and mealworms. The mealworms, composed of 3/4 protein, were chosen due to a United Nations study recommending it as a foodsource for the poor and undernourished of the world; however, it has met with resistance when tried with Western astronauts. They also have a tendency to escape their farming environments. Growing mealworms the size of fingers took mere weeks. The mealworms were fed the leftover and inedible parts of the vegetative produce that was harvested.[2][8]

The mission's ecological system was to be a testbed for the controlled ecological life support system (CELSS) for the permanent Chinese space station of the China Manned Space Engineering Office (CSME). The BLSS system used on the mission was at the time the most advanced ever fielded.[6]
