Nie Haisheng, Liu Boming and Tang Hongbo are astronauts on the Shenzhou 12 mission, Nie Haisheng is the commander, Zhai Zhigang, Wang Yaping and Ye Guangfu are backup astronauts.

After the Shenzhou-12 spacecraft is put into orbit, it will dock with Tianhe core module by autonomous rapid rendezvous and docking. At this time, Shenzhou-12 will form an assembly with Tianhe core cabin and Tianzhou-2 cargo spacecraft.

Among them, the Tianhe core cabin is where three astronauts live and work, so the problem comes. In the next three months or so, how should astronauts survive here and what work should they complete?

According to expert Shi Liming, the Tianhe core cabin is very large, with a length of more than five floors, a wider diameter than the carriages of trains and subways, and a larger volume than any cabin of the International Space Station.

Tianhe core cabin has six areas: working area, sleeping area, health area, dining area, medical supervision and medical insurance area and sports area. Astronauts' food, clothing, housing and transportation are all completed in these areas.

Clothing: In the core cabin of Tianhe, astronauts don't have to wear heavy spacesuits. However, due to the astronauts' extravehicular activities, the extravehicular radiation is serious. In order to protect the life, health and safety of astronauts, China customized the extravehicular spacesuit for them. The weight of each extravehicular spacesuit reaches 100 kilograms, and a spacesuit has six floors, which has the functions of radiation protection, high and low temperature protection, pressure adjustment and so on, and is also equipped with a life support system.

Food: The dining area has microwave ovens, refrigerators, water dispensers, folding tables and other furniture and appliances. Moreover, the Tianzhou-2 cargo spacecraft carries 120 kinds of space food, including Chinese food such as kung pao chicken and shredded pork with fish flavor, which will never wronged our astronauts. Some netizens even said: Astronauts eat better in space than I do.

Accommodation: In fact, in the weightless environment, astronauts can not only sleep lying down, but also sleep standing, sleeping backwards, sleeping sideways and so on. Some foreign countries will let astronauts sleep on the wall. However, every astronaut in our country has his own bedroom, and he can sleep in his own room, which can ensure that his sleep will not be disturbed and let the astronauts get a full rest.

Ok: Usually, astronauts mainly stay in the core cabin of Tianhe, so there is little demand for travel. However, after completing the mission, the astronauts will return to the Dongfeng landing site in the spacecraft return module.

Life: China Space Station is located in low earth orbit. After the astronauts move in, a series of changes may occur in the body, such as muscle atrophy and bone loss. It doesn't matter much if the space mission takes a short time, but the longer the mission takes, the more serious the situation will be. This change cannot be reflected in space, but when astronauts return to the ground, they may not be able to adapt to the gravity environment of the earth in severe cases.

The three astronauts of Shenzhou 12 will perform a long-term mission in China Space Station for about three months. If they don't exercise for a long time, they may not be able to adapt to life on the ground. As a result, experts set up a fitness area for them in the Tianhe core cabin.

Fitness equipment includes space treadmills, space bicycles, resistance stretchers, etc. Astronauts can exercise here if they have nothing to do.

In addition, the space station in China has mobile WiFi, and astronauts can also call their families through private voice channels. It can be said that the three astronauts made full preparations from food, clothing, housing and transportation to life during the mission.

According to the task arrangement, after the three astronauts settle in the Tianhe core cabin, they will complete four aspects of work: carrying out the daily management of the core cabin assembly; Carry out extravehicular activities and operations; Conducting space science and technology experiments; Carry out astronauts' own health management.

After the astronauts enter the Tianhe core cabin, they must first sort out the materials carried by the Tianzhou-2 cargo spacecraft, and then the astronauts need to install and debug various equipment. After installation, they should run checks to ensure that all kinds of equipment can be used normally.

After the indoor equipment installation is completed, the astronauts will leave the cabin, but instead of going to see the stars and the moon, they will install debugging equipment outside the cabin. Compared with the cabin, extravehicular activities are very inconvenient, because the extravehicular spacesuit is very heavy, so astronauts sometimes have to operate with the help of mechanical arms.

Installing equipment is only part of the astronaut's job. Astronauts also need to carry out scientific experiments and technical experiments on the space station, pack and sort out garbage, and maintain the assembly of core modules. It can be said that the task of the three astronauts is very heavy, but they are ready.

Finally, I wish our three astronauts a smooth return to Earth after completing the mission of China Space Station. We are waiting for your good news on earth!
