The manned space launch site has an "outdoor paradise" with red walls, white tiles, green trees and blue sky, which corresponds to Populus euphratica's interest in weak waterfront. Looks chic and elegant. This is the "enchanted gardens" in the astronaut area. The core building of the astronaut area, Wentian Pavilion, is the place where astronauts enter the launch site for short-term life, training, medical supervision and insurance, isolation and epidemic prevention, and preparation for boarding. What are astronauts doing in the last few hours before they go into space?

Astronaut Yang Liwei sat in the manned spaceship cabin. Good sleep is very important. Does going into space sound exciting? If you are an ordinary person, you will definitely be too excited to sleep. So, will astronauts be excited? Will they sleep well? Don't worry about this, because the psychological quality of astronauts is very strong, and it is no exaggeration to describe it as calm. Generally speaking, the astronauts' work and rest time is arranged according to the launch time, and 8 hours of sleep time must be guaranteed. For example, the launch time of the next day is 9: 00 am, so astronauts need to start 8 hours of continuous sleep around 8: 00 pm the day before.

Astronaut Yang Liwei lived in this room before the launch. Why do you have to sleep for 8 hours? On the one hand, a good sleep can ensure that astronauts have a good mental state when performing tasks. On the other hand, the quality of astronauts' sleep also affects the results of astronauts' pre-flight physiological tests to some extent. It can also be replaced before launch.

Going into space should be the most anticipated moment in every astronaut's heart, and it is also the most sacred moment in their lives. However, if their psychological fluctuations are great, or there are any potential physical problems before launch, they may still be replaced. The standard is the physiological test before the war.

This physiological test is more important than usual, mainly including ECG, temperature, blood pressure, heart rate and weight test, as well as simple internal medicine, surgery, neurology and five formal examinations. If the selected astronauts are too excited, excited or nervous, there will be slight physiological changes. All these changes can't escape the "eye-catching" of astronaut psychologists, medical supervisors and medical insurance personnel. If the candidates of the first echelon are abnormal during the inspection, they can be replaced by the backup echelon.

About four hours before launch, astronauts will start eating. In order to ensure the astronauts' food safety and balanced nutrition, there will be a special dietitian to distribute every meal for the astronauts. In addition to balanced nutrition, we should also pay attention to choosing foods that do not stimulate the astronauts' stomach before launch. Usually choose noodles and jiaozi. After eating this meal, before leaving the astronaut apartment, the astronaut will write his name and the time of exploration on the dormitory door as a souvenir, and this moment will remain in the historical memory forever. The astronaut signed the door before going into space. Say goodbye to everyone through the glass. Two hours and thirty minutes before the launch, the first astronauts will put on their spacesuits in the cabin and come to the isolation hall through a special passage to say goodbye to everyone.
