What benefits can space technology bring us?

Satellites can also provide farmers with crop yield estimation and pest prediction, and provide fishermen with fish location information. "China's multi-mode microwave remote sensor has realized the ability to observe the earth all-weather and all-day, and it is self-evident that it can see marine products, where there are fish schools and how big the fish schools are."

Medicine

Using space technology to develop man-made organizations

NASA has developed a "bioreactor" for research. These reactors are used to make human tissues such as ligaments. They neutralize gravity, so cells can grow as if they were in the body. The miniature heart pump is developed by using the fuel pump technology on the space shuttle.

Space sickness drugs can also treat seasickness.

The first case of space disease was accompanied by manned space flight, which was a directional obstacle caused by weightlessness. Cosmic medicine has developed a variety of drugs and equipment to solve the above and other diseases caused by long-term weightlessness. Some of these methods can also be used to treat common diseases, such as seasickness.

From the life-threatening "artificial heart" and kidney dialysis technology to a pair of sports shoes on the feet, all of them are "masterpieces" of aerospace technology.

[Space Vegetables]

Space has a unique high vacuum, strong radiation, microgravity and other environments that are difficult to simulate on earth, providing an ideal experimental site for scientific research. Using special space environment to induce plant character variation and cultivate new varieties with excellent characters is space breeding.

Since 1987, more than 300 kinds of crop seeds have been developed in China, and more than 50 strains have been planted and popularized in a large area.

According to incomplete statistics, 43 strains have been planted and popularized in large areas in China, and there are space breeding bases in Beijing, Shanghai, Heilongjiang, Jiangsu, Gansu and other places. "Hangjiao No.3 and No.4", "Space Cucumber" and "Hangqie 1 No.3" ... The nutritional content of these delicious space vegetables has generally increased by 30% ~ 46%, and they have been put on the table of ordinary people's homes.

Of the more than 1000 new materials developed in China in recent years, 80% were developed under the traction of space technology. Nearly 2,000 achievements in space technology have been transplanted to various sectors of the national economy.

Among the millions of protein in human body, less than 1% is known. "In the microgravity environment in space, protein can grow very large crystals, which can be used for structural analysis. If it is applied to pharmaceuticals, every successful protein structural analysis will produce a new product. "

It is reported that the R&D cost of developing a new drug in the United States is generally between 500 million and 654.38 billion US dollars, with an average time of about 5 years. Undoubtedly, studying protein in the space environment will greatly improve the efficiency and quality, and the results may be used to change human health, solve problems such as food and medicine, and greatly improve people's quality of life. Hu Wenrui estimates that it may take decades to turn these into reality. However, once the results are applied, the changes of human life will be unpredictable. "

Space food facilitates daily life.

Many freeze-dried foods in supermarkets are foods eaten by astronauts.

Nuclear balance prevents the outbreak of full-scale conflict

The space race has enabled the development of some destructive technologies. Both superpowers are equipped with a large number of powerful nuclear missiles that can destroy the whole world in just a few minutes. Many historians have pointed out that a delicate "balance of terror" helps to prevent a full-scale conflict between East and West.

No matter how far away the place is, you can keep in touch.

Iridium telephone system has been widely used by the US military. This communication system allows you to keep in touch with the transmitting antenna of a remote mobile phone, such as deep in the jungle or the Arctic wilderness.

You won't get lost anywhere.

The global positioning system depends on the satellite network around the earth. Global Positioning System (GPS) satellites continuously broadcast time and position data. The receiver can calculate its distance from the satellite according to the time required to receive the signal. The receiver can calculate its accurate position by using the relevant data of three or four satellites.

Communication satellites make the world a "village"

1 The "Dianxing" satellite launched in 9621can receive, enhance and transmit signals in real time.

1964, we launched the first satellite that can really keep its relative position with the earth unchanged. During half a century's operation, communication satellites have brought earth-shaking changes to the world. Communication satellites not only triggered the revolution of cheap instant communication equipment, but also increased our understanding of distant places in the world. Communication satellites can also enable people in remote areas to receive education by broadcasting.
