Provide strong support for China to build a smart society.

Key technologies, cutting-edge leading technologies and subversive technological innovations provide strong support for building a digital China smart society into a powerful country in science and technology, quality, space and network.

The key technologies are as follows:

Key common technology is a management science and technology term published on 20 16. Technology that can be combined with other technologies, widely used in many industrial fields, and can have a profound impact on the technological progress of one industry or multiple industries.

The space is introduced as follows:

Space flight, also known as space flight, space flight, space flight or space flight, refers to various activities of entering, exploring, developing and utilizing space (that is, space outside the earth's atmosphere, also known as outer space) and celestial bodies outside the earth.

Space activities include space technology (also called space technology), space application and space science. Space technology refers to a comprehensive engineering technology that provides technical means and guarantee conditions for space activities. Space application refers to the use of space technology and its developed space resources in scientific research, national economy, national defense construction, culture and education.

Space resources refer to all kinds of environment, energy and material resources that can be developed and utilized by human beings outside the earth's atmosphere, such as high and remote positions in space, high vacuum, ultra-low temperature, strong radiation, microgravity environment, solar energy and material resources of celestial bodies outside the earth.

Life in space is introduced as follows:

The cosmic environment is extremely harsh, and the main factors harmful to human body are high vacuum, high hypoxia, cosmic radiation, temperature difference and so on. These unfavorable factors will cause serious harm to the human body.

In this environment, astronauts cannot live and work. Facing the severe space environment, how to ensure the life safety of astronauts? Our scientists and technicians have developed a closed environment that is basically isolated from the outside world, that is, a closed cockpit, to protect astronauts.
