China's space station can run in orbit for at least 10 years. What is the purpose of building a space station?

What's the point of building a space station?

Many related experiments can be carried out on the space station, such as science and technology, agriculture, astronomy, aerospace, chemical industry, medical care, electronics, food and so on.

Specifically, first of all, many scientific experiments under space conditions cannot be carried out on the surface of the earth. Such as zero gravity and high radiation conditions. For example, when a flame burns on the earth, it is in the shape of a water drop. In the absence of gravity, according to speculation, the flame should be spherical and it is impossible to burn for a long time. But according to the experiment of the space station, the flame can burn for a long time without gravity, and there is no thermal convection.

Secondly, experiments on the space station can also stimulate young people's interest in space science and technology.

For example, Wang Yaping, an astronaut from China, gave a lesson to the students in the space station on the morning of June 20th 13. The course content includes concepts such as how objects move in weightlessness, surface tension of liquid, Newton's law and so on.

The next experiment of the space station will also greatly improve the lives of ordinary people.

For example, many crop seeds are cultivated in space environment at present. So far, about 22 provinces and cities in China have participated in the cultivation of new varieties with space stations. There are 38 qualified varieties. The varieties involved are rice, wheat, vegetables, wood, garden plants with plants and so on, some of which have been planted in Guangxi, Fujian, Gansu and other places. Fourth, the establishment of a space station is of great significance to safeguarding national security. In the process of developing the space station, many scientific and technological achievements can be born. For example, when the United States implemented the Apollo program, it also produced nearly two-thirds of the existing technology in the United States.

The space station is connected with photographic equipment for observation.

Fifth, the astronomical observation equipment on the space station has obvious advantages over the ground and satellites, and can be used to study the position, trajectory, material state and changing law of celestial bodies in the universe. Some astronomical phenomena, such as solar flare and dark stripe explosion, can be observed in time, which plays an urgent role in protecting the earth.

Sixth, when humans can travel in space, the space station will be used as a supply transit station like a car service area. On the space station, probes from various planets can refuel on it. Greatly reduced the cost of exploring space.

To sum up, the function of establishing a space station is to carry out scientific experiments, stimulate interest in science and technology, improve people's lives, safeguard national security, and observe astronomy and phenomena. Space station is of great significance to human production and life and further exploration of the universe.
