Astronaut training includes professional basic theory training, physical training, special endurance and adaptability training, professional technical training, flight procedure and mission simulation training, life-saving and survival training, flight skill training, psychological training, large-scale joint exercises, etc. All of which belong to three major aspects, namely professional basic knowledge training, vocational skill training and flight mission training. After the basic theory training is selected into the astronaut team, professional basic theory training will be carried out first. The learning contents include space, atmosphere, astronomy, meteorology, geophysics, aerodynamics, rocket and spacecraft design principles, spacecraft system and component structure, navigation and control, communication, telemetry and remote control, mathematics, computers, foreign languages and other theoretical knowledge required for aerospace. In addition, there are aerospace medicine and physiology. Improve their cognitive level through training, and lay the foundation for subsequent training.
