 How to live in the Moon Palace?


In July 9, 2017, the first group of Moon Palace one experimenters worked in the plant cabins. Beijing News reporter Wujiang photo Leafy vegetables grow green and oil, cucumber is hung on branches, volunteers harvest wheat, and deal with waste. Through the porthole of red and blue light, the real life picture of Moon Palace one is displayed in front of the public. On the 21-22 th of April, Beihang University opened the science base of Moon Palace No. 1 for the public. Moon Palace No. 1 is the first human integrated airtight experiment system for the first third biological regenerative life support foundation in the world, and is the first successful four biological chain ring system in the world. The Moon Palace 365 experiment, which is currently carried out, is a comprehensive experiment aimed at the manned lunar base and Mars exploration program. The main task is to study how a biological system can provide life support for the crew of different metabolic levels and keep the system stable, for which 8 volunteers need to work. We have to go in three shifts and close our lives for 365 days. Uncover 1 What is the Moon Palace one? It consists of 1 integrated modules and 2 plant cabins. Moon Palace No. 1 consists of 1 integrated modules and 2 plant compartments, with a total area of 160 square meters and a total volume of 500 cubic meters. The integrated module includes living rooms, personnel exchanges and workshops, washrooms, waste disposal and insects. Each plant compartment is divided into 2 plants, which can independently control environmental conditions according to different plant growth needs. According to Liu Hong, chief designer and chief scientist of Moon Palace No.1, plant cabins are mainly planted with staple food, including wheat, potatoes, carrots, scallions and so on. Plant cabins II planting vegetables, such as soybeans, beans, cucumbers, tomatoes, peppers and so on. Plant cabin I attached a single transparent membrane, from which can not see the external world; and plant cabin IIs suspension windows are not covered with film, inside and outside. Liu Hong explained that there were cameras in the cabin, cameras were used to capture the behavior of cabin personnel, and some psychological research was carried out. On the one hand, the selection of plant species should consider the nutritional needs. According to the nutrition matching, the production efficiency is high and the cultivation technology is simple. And, according to the needs of the plant to set up the light formula, the plant is high in demand for red and blue light, the most red light, followed by blue light, so the plant cabin looks like red and blue light. Liu Hong introduced it. Uncover 2 How to realize the 100% cycle of water and gas? Waste water purification, water vapour condensation and water production are used to configure nutrient solution, drinking and so on. The closure degree of the Moon Palace No. 1 system can reach 98%, and the water and oxygen in the cabin can achieve 100% cycle regeneration. How does the 100% water cycle come true? Liu Hong told reporters that human waste water, including urine, sanitary waste water and other purification treatment, then used to configure nutrient solution, plant cultivation. Plant evaporation and human breathing will produce water vapor, water vapor will go into the air, and collect the condensate collection system and concentrate for purification, for people to drink, wash and wash clothes, etc. This is very similar to the source of water that we drink at ordinary times. We usually drink water from rivers and lakes, and rivers, lakes and water are also air condensate water. Liu Hong explained. How does the 100% air cycle come true? In the system, plants are autotrophic organisms, consume carbon dioxide, produce oxygen, people and animals and microbes are heterotrophic organisms, consume oxygen and produce carbon dioxide. There is a set of air circulation system in the cabin, the oxygen rich air produced in the plant cabin will be hit into the integrated cabin. The carbon rich air produced in the comprehensive cabin will be purified to the plant cabin after purification, thus recycling oxygen and carbon dioxide. How does the solid waste deal with it? There are waste disposal rooms in the cabin to deal with solid and liquid wastes. Solid waste, including human excrement, plant straw and kitchen waste, will enter the waste disposal room and be treated with biotransformation agents. Liu Hong said. Uncover 3 The schedule is very full. You can browse the Internet and catch up with the opera. In May 10, 2017, the Moon Palace 365 experimental program was launched, and the experiment lasted for 365 days. There were 8 volunteers in the group, divided into two groups, with 3 classes. The 1 group was the first class, lasted for 60 days, and the 2 group was second classes. The duration lasted for 200 days, and the 1 group was again third classes, with a duration of 105 days. What activities do volunteers do in the cabin every day? Liu Hui, one of the 8 volunteers, told reporters earlier that the schedule was very full. He basically got up at half past six and went to bed at eleven in the evening. Every day, he also measured and recorded body weight, body temperature, blood pressure and blood oxygen saturation. The volunteers also have recreational activities in the cabin. Liu Hui introduced, from 6 evening to eat dinner, volunteers to cook, eat, chat, inside the Internet can watch the news, understand the state affairs, also chasing hot films, what happens outside through the network know. How do the volunteers eat their stomach in the cabin? In the Moon Palace 365 experiment, 80% of the food comes from recycling, and 20% is oil, salt and sugar and some meat and other imported foods. Liu Hong said. It is worth noting that Tenebrio molitor is also the food in the cabin. It is reported that it can provide a rich food protein for volunteers, and can also degrade part of the waste to accelerate the circulation of material, and also play a certain role in psychological adjustment. It has the characteristics of rich nutrition, some waste disposal, easy cultivation, safe eating and delicious taste. ialogue Moon Palace No. 1 chief engineer Liu Hong: Although it is still on the ground, it will be spaced in space Liu Hong: Moon Palace 365 experimental process is dense, many visitors will also affect the experiment, has not been publicly visited, this time by third space day opportunities, open to the public, hoping to stimulate the public, especially young people to scientific enthusiasm, to train follow-up power. Beijing News: the experiment has entered countdown. How is it going now? Beijing News: during the Moon Palace 365 plan, did you encounter any difficulties? Liu Hong: the bigger difficulty is that the experiment lasts for a long time, and it crosses all kinds of festivals. No matter it is mid autumn festival or Spring Festival, members must be on duty. On the technical level, the members of the cabin stayed for 200 days, breaking the world record of 180 days in the biological regeneration life support system created by Russian researchers. We have to ensure that these 200 days are healthy from psychological to physiological. Moreover, the system has changed shifts, with various metabolic levels alternating. It is also a great challenge to ensure timely control of the system. Beijing News: will Moon Palace 1 experiment be applied to space? Liu Hong: at present, there is no space application level in the world, stay in the stage of ground research, and then do space carrying, such as carrying the lunar probe, Mars probe, space station, and studying the influence of the space environment on the system. Through the contrast of earth and earth, we can analyze the correction parameters and the correction model. In this way, the parameters and models of the whole system can be applied to space. The Beijing News: will the experiment of Moon Palace 1 be applied to peoples livelihood? Liu Hong: plant cultivation technology can be well applied to plant factories, which can save land, product quality and pollution problems are well controlled. The spectral formula and the circulation technology of nutrient solution can be further applied in agriculture and applied to modern precision agriculture. Beijing News: in addition to agriculture, there are other technology transformation? Liu Hong: the family and office space in Moon Palace one can also be transformed into technology, such as family ecological housing and plant cultivation at home. Because plants are not only food, they can also increase air humidity, increase negative oxygen ions, and regulate peoples emotions and psychology. This experiment has done a lot of experiments. Different plants will do many researches when they look at it, cultivate it and eat it. Next, we can make some products and equipment so that ordinary people and people without relevant skills can operate well.
