On June 5, 2022, the Shenzhou 14 spacecraft was successfully launched, carrying three astronauts. Three astronauts need to stay on the manned spacecraft for six months and do some scientific research. Every astronaut brought personal belongings, such as astronaut Chen Dong. He said that he had assigned homework to his children. He said that he would check the children's homework when the spaceship came back. He said that he would pat the earth during the break, which was a sense of ceremony. Astronaut Liu Yang is the only female astronaut in this mission. She wants to take more photos in space with her children's wishes and wishes. Astronaut Cai boarded the spaceship for the first time, bringing some TV dramas, movies and plant seeds, and wanted to grow vegetables on the spaceship.

It is worth noting that before the three astronauts entered the spacecraft, the breakfast they ate that day was steamed bread, and the breakfast of other staff members was also steamed bread. Steamed bread has a good meaning, which represents? Did the package succeed? The meaning of. All three astronauts boarded the spaceship with blessings and thoughts for their families. Because the work in the spaceship is very complicated and challenging, the selection of astronauts is also very strict and demanding.

There are many conditions for selecting astronauts, which require very serious and meticulous scientific research spirit, the situation of three people getting along, their age and forgotten flight experience. In addition to personal requirements, there are also requirements for the tacit cooperation of the trio, which should have both characteristics and * * *. And the most important thing is to be able to endure the hard life in space for half a year.

Astronauts must undergo strict training after selection, such as simulating the environment when doing tasks in the space station and how to deal with emergencies reasonably. These must be trained in advance. In terms of living conditions, astronauts' physical and psychological qualities, they will receive very intensive training. In addition, there are still some dietary aspects that need to be improved. Because it is inconvenient to eat in space flight, you should get used to it in advance on the ground. Some foods should not only be convenient, but also pay attention to a balanced diet.
