China's space program in 2 1 century

Generally speaking, the significance of developing manned space flight in China is as follows: 1. Manned space flight is one of the most complicated systems engineering in human history, and its development depends on the development of the whole scientific and technological level. At the same time, it also affects the development of the whole field of modern science and technology, and puts forward new development requirements for all fields of modern science and technology, thus promoting and promoting the development of the whole science and technology. The development of a country's manned space technology can reflect the country's overall scientific and technological and high-tech industrial level, such as system engineering, automatic control technology, computer system, propulsion capability, environmental control and life support technology, communication, remote sensing and testing technology. It can also reflect the development level of modern mechanics, astronomy, earth science and space science in this country. Without the research and development of aerospace medical engineering, it is impossible to send people into space and live and work safely, healthily and effectively. The famous "Apollo" program in the United States was implemented from 196 1 to 1972, and it cost 24 billion dollars to complete six missions to the moon, sending 12 people to the moon and returning to the ground safely. It not only achieved the political goal of the United States to catch up with the Soviet Union, but also promoted the development of American science and technology, especially propulsion, guidance, structural materials, electronics and management science. Today, with China's comprehensive national strength increasing, the development of manned space flight can greatly realize the leap-forward development of China's scientific and technological strength. 2. The development of manned space flight is the direct embodiment of the comprehensive national strength of all countries today. All developed countries regard enhancing comprehensive national strength as the primary goal of their development strategy, and its core is to develop high technology, with manned space technology as one of its main contents. If a country can send its astronauts into space, it can not only reflect the national strength, but also greatly increase the pride of the former people, improve the national spirit and enhance cohesion. In particular, once the current "shenzhou spaceship" project is successful, it will attract the attention of the whole world like the "two bombs and one satellite" project in the 1960s, and enhance China's international status. Undoubtedly, the development and utilization of space resources will become more and more important in the future when the earth's resources are exhausted. Manned space technology obviously plays an important role in it. Now we know that the vast space is a huge treasure house with abundant resources, and manned space flight is the bridge to this treasure house. The "space factory" can be almost like magic. Under the conditions of microgravity, vacuum and no convection, it is conceivable that if the first three industrial revolutions have brought great wealth to mankind, the "new industrial revolution" triggered by space technology will eventually change the existing model of the whole human society, and the word "space manufacturing" will flood every corner of the whole market. If China wants to occupy a place in the future market, it cannot do without manned space technology, which is the basis of developing space resources. In addition to the above points, the development of manned space flight will mark the beginning of a new stage of human development. Scenes that can only be seen in science fiction movies before will be realized step by step in our real life. It will no longer be impossible for human beings to move to other planets to live and live, and it is entirely possible to develop better living space to solve the present situation of increasingly crowded living space, especially for China. By then, mankind will face more new tests and choices. The aerospace industry is an internationally competitive undertaking. The development level of space technology represents a country's comprehensive national strength and scientific and technological level. As the earliest developed space powers, it is well known that the United States and the former Soviet Union/Russia monopolize and block space technology. China's space industry got off to a difficult start, when the West blocked it and the former Soviet Union refused to support it. From the very beginning, China was determined to develop its space industry independently. It is under the guidance of this correct principle that, after the hard struggle of several generations of astronauts, China began to own its own liquid rocket and gradually owned its own satellite, until today it successfully launched its own manned spacecraft. If we didn't have the technical strength and experience to develop and successfully launch a self-returning satellite, maybe we wouldn't have our own shenzhou spaceship today. Only self-improvement can cooperate. The peaceful development of space is the general trend, and China has also participated in some international cooperation, such as cooperating with the European Union to develop a satellite navigation system. However, most of the international cooperation in the space field is strong cooperation, and all parties have considerable strength. For example, Russia may plan to cooperate with the United States to develop the "Peace -2" orbital station and space plane; The United States, Russia, Japan, Canada, Brazil and ESA 1 1 Member States are jointly implementing the Alpha Permanent International Space Station program. These countries and organizations have considerable scientific and technological strength. If China does not have its own strength, technology and advantages with its own property rights and characteristics, where can international cooperation start? Independence and self-reliance do not prevent China from learning from the development experience of other advanced countries and cooperating with them; On the contrary, it has laid a solid foundation for China to learn from the development experience of other countries and carry out international cooperation. As a developing country, being able to independently develop manned spacecraft with international advanced level fully embodies China's own space technology strength, thus it can be called "the world's space power" in the true sense. Perhaps this is the real reason why the United States, Russia, Japan, Germany and other countries are particularly concerned about whether China seeks international cooperation. Therefore, China's road of independence and self-reliance is determined by the characteristics of the space industry itself, and it is also the correct way for China's space industry to stand on its own feet. Only by self-reliance can we be self-reliant; Only self-improvement can cooperate. Aerospace industry is an industry that has a bearing on the overall situation. The development and breakthrough of space technology is not only crucial to the development of space industry itself, but also to the development of other related disciplines and industries. Since the implementation of manned space flight project 10, China has broken through a large number of core technologies with independent intellectual property rights, and improved the level of China's space science and technology and related disciplines, especially the overall level of emerging disciplines such as information, materials and energy in the 2 1 century, which not only laid a solid foundation for the sustainable development of the space industry, but also provided a solid backing for meeting the extensive demand of national economic construction for space technology and its industrialization under the increasingly fierce international competition. The firmness of these foundations and support lies in our insistence on independence. References:
