Opened up the horizons, right, for ordinary people, and only this, just like the beginning of that first lesson in the Chinese astronauts in the vacuum under the water droplets can float the experiment, to give people a desire to know, so that people understand the vastness of the universe.
Do a variety of scientific experiments. For example, we eat space peppers is biological breeding.
Astronauts go to space, in order to explore more human has not been involved in the knowledge or things. July 20, 1969, for the entire human society to explore the understanding of space is a huge progress, epoch-making significance. The U.S. Apollo program was a success, and the Apollo 11 spacecraft landed safely on the moon and set foot on its surface. A small step on the moon is indeed a big step for human civilization.
The movie "Wandering Earth" may explain why we should explore space, the depletion of resources, the deterioration of ecology, the greenhouse effect and a series of other problems are the reason for human beings to go to explore space, is to prepare for the future. And as a country's comprehensive strength grows stronger, the success of exploring the unknown will lead to a higher and higher international status.
Many big countries have spent a lot of money on experiments and invested a lot in exploring space. But some people may ask, even in a world power like the United States, there are people at the bottom who are not living in poverty, and there are citizens who can't eat or wear warm clothes, so why can't we turn this huge investment into relief for the poor families? What can the space sector offer us?
China has also been vigorously developing its space program over the past few years, and is actively promoting the construction of a manned Chinese space station, which is expected to be completed around 2022. China's aim is to build the space station into a space base for conducting large-scale space science experiments and applications.
Exploring space comprehension costs a lot of money, but it's really necessary. This is especially true now that China needs to improve its international standing and take the lead in mastering advanced technologies in order to gain a foothold in the competitive world landscape. Simply put, exploration is to allow the people to have the conditions to enjoy higher resources, this new crown epidemic is the best proof.
Hello
Don't forget to take it after reading it carefully!
Benefits of space technology
Communication]
Satellite TV Mobile phones
On April 8, 1984, China's first experimental communications satellite was successfully launched. Today, China's communication satellites undertake the transmission of dozens of television programs and 30 foreign broadcasts.
The World Cup, the Olympic Games ...... satellite TV allows us to stay at home, know all the world's events. Not only that, the use of aerospace technology to develop a digital TV set-top box, but also can receive cable digital TV signals, so we see more channels, more clear programs.
The newest addition to the lineup is the newest addition to the lineup, the newest addition to the lineup, the newest addition to the lineup. Over the decades, and the people close to the heart of the "space civilization", of course, less meteorological satellites to provide "weather forecasts". China Xi'an Satellite Control and Measurement Center activity measurement and control of the recovery of the landing site of the Department of Meteorological Station weather forecast team leader Li Yonghui said: "The current weather forecast method used for the recovery of the spacecraft can also be used to serve the weather forecast of some sports events. For example, it can be directly used for the Beijing Olympic Games in a certain venue, a certain period of time of the weather forecast, and can even be refined to predict the weather changes within half an hour."
China is a country prone to natural disasters, with annual losses of up to 200 billion yuan. In recent years, China has made extensive use of satellite remote sensing to forecast and assess typhoons, rainstorms, mudslides, and so on, enabling the country to reduce losses from natural disasters by tens of billions of dollars each year.
Satellites can also provide farmers with crop yield estimates and pest forecasts, and fishermen with fish location information. "China's multi-modal microwave remote sensors have achieved all-weather, all-day, all-time earth observation capability, able to see the ocean's physical production, which place has fish, fish roughly how much can be judged, the role is self-evident." Chang'e 1 satellite deputy chief designer Huang Jiangchuan said.
Medical]
Artificial tissues developed with space technology
NASA has developed "bioreactors" for research, which are used to create human tissues such as ligaments. They neutralize gravity so cells can grow as they would in the body. The miniature heart pump was developed using fuel pump technology from the space shuttle.
Space sickness drugs can also cure seasickness
The first case of space sickness followed manned spaceflight, and it was disorientation caused by weightlessness. Cosmic medicine has developed a variety of drugs and devices to address these and other ailments caused by prolonged weightlessness. Some of these methods can also be used to treat common ailments such as seasickness.
Smart materials to improve technology for prosthetics
NASA's research into the next generation of space shuttle technology will have wide-ranging implications. Research is underway into "smart" materials that have memory of their original shape even after they have been altered. Such materials may help to improve the technology for making prostheses.
Derivation of devices for measuring physical conditions
Non-invasive sensors for measuring pulse and other physical conditions are directly derived from similar devices used to monitor astronauts.
New drug development
"Nearly half a century of human space activities have yielded a large number of scientific results, some of which have been used to improve human life, and some of which will be embodied in people's lives in the near future." Hu Wenrui, academician of the Chinese Academy of Sciences and member of the International Academy of Astronautics, explained this in detail.
From the life-threatening "artificial heart", kidney dialysis technology, to the feet of a pair of travel shoes, are space technology "masterpiece".
[Space vegetables]
Space has a difficult to simulate on Earth, the unique high vacuum, strong radiation, microgravity and other environments, for scientific research provides an ideal experimental place. Utilizing the special environment of space to induce variation in plant traits and cultivate new varieties with excellent traits is space breeding.
Since 1987, China has conducted more than 300 kinds of crop seed satellite piggyback test, completed more than 50 strains of large-area planting promotion.
Incomplete statistics show that, at present, China has 43 strains in large-scale planting and promotion, Beijing, Shanghai, Heilongjiang, Jiangsu and Gansu and other places have space breeding base. "Aero-pepper three, four," "space gourd melon," "Aero-eggplant one, three," ...... these tasty space Vegetables, nutritional content generally increased by 30% to 46%, has been placed on the table of ordinary people.
China in recent years, more than 1,000 kinds of new materials, 80% is in the space technology under the traction of the development of the completion; nearly 2,000 space technology results have been transplanted to various sectors of the national economy.
Hu Wenrui introduced, in the human body of millions of proteins, humans have understood less than one percent. "Under the microgravity environment in space, proteins can grow very large crystals that can be used for structural analysis. If applied to pharmaceuticals, every successful analysis of the structure of a protein will produce a new product."
It is reported that the United States for the development of a new drug research and development costs are generally in the range of 500 million to 1 billion U.S. dollars, an average of about five years. The study of proteins in the space environment will undoubtedly greatly improve the efficiency and quality, and the results may be used to change the human health situation, solve the problems of food, medicine, etc., greatly improving the standard of living of human beings.
Can discover more unknown things, can promote the development of science and technology, but also can explore our unknown areas, but also to expand the insights of everyone. Can take the most perfect results
