With the theme of "force · awakening", the conference held two-day brainstorming, six explosion forums, gathered the ground application of global trendy technologies, crossed the collision of cultural and artistic inspiration, and looked for the key to the future < p > at the conference, Gu Yidong, academician of the Chinese Academy of Sciences and chief expert of space science of China's manned spaceflight project, gave a keynote speech on China's manned spaceflight and applications. He mentioned that mankind has entered the space age for 64 years and has made epoch-making achievements in the history of development. Human space activities have profoundly changed the social outlook, greatly expanded the territory of human activities and cognition, profoundly changed human's outlook on the universe and nature, and become one of the remarkable symbols of contemporary scientific and Technological Development and social progress. Application satellites and business expansion have become an indispensable infrastructure for human social life, deeply penetrated into all aspects of economy, industry and people's life, and greatly promoted the process of globalization and informatization < p > academician Gu Yidong introduced that the construction of China's space station has begun, and will aim to build a national space laboratory, become the most important near earth space comprehensive laboratory in the next decade, and carry out long-term and multi field space science and application research. At present, four fields and mission objectives have been planned, including space life science and human body research, microgravity physics research, space astronomy and earth science. It is expected to effectively promote the formation and evolution of dense celestial bodies such as cosmic dark matter, dark energy and black holes, the law of matter essence, the essence of life phenomena and the response and change law of human beings in space, And breakthroughs in major frontier scientific issues such as the sustainable development of the earth < p > he said that the construction and operation of China's space station is a historical opportunity to promote the development of China's space science and application. It will make a unique contribution to the historical process of building China into an aerospace power and a world power in science and technology, and provide profound scientific and technological accumulation for China's manned space exploration near earth and far away in the future.

First of all, I would like to start from a general background, that is, the general situation of human space activities and manned spaceflight, and then talk about some scientific applications of manned spaceflight in our country < p > as we all know, more than 60 years ago, the first man-made satellite of the former Soviet Union went to heaven in 1957, which should be said to have opened the space era of mankind. In the past 64 years, we have made epoch-making achievements in the history of human development. Human beings have landed on the moon, various probes and unmanned probes have landed on the moon, Mars and asteroids. Human exploration footprints have spread throughout the entire solar system, built space stations, and especially carried out large-scale space applications and space exploration. Therefore, we can say that human space activities have profoundly changed social changes, greatly expanded human activity space and territory, profoundly changed human understanding of the universe and nature, and become one of the remarkable symbols of contemporary scientific and Technological Development and social progress < p > these are two pictures. This is a scene of Apollo landing on the moon; This is the largest international space research facility of mankind, more than 400 tons, 110 meters long, and the largest man-made space flight device < p > in terms of space applications, a large number of application satellites have been launched, including earth observation, communication and navigation. We will no longer talk about their functions carefully. It has also formed a large-scale industry. Some people say 300 billion or 600 billion. Its scale, directly and indirectly, is at least $3 trillion. Therefore, due to the expansion of the number of parts launched on orbit and applications, it has become an indispensable infrastructure for human society. Our weather forecast is unimaginable without meteorological satellites. It also penetrates into all aspects of economy, industry and human society, and greatly promotes the process of globalization and informatization. If you think about it carefully, you can feel this very clearly < / P > < p > there may be many people who do not particularly understand space exploration. Space science is to use space vehicles to study the space between the earth and the sun and the space of the whole solar system, as well as the universe, its physics, chemistry The synthesis of such a large discipline as the law of natural phenomena such as life < p > we know the mechanism of solar activity and that the solar wind and plasma emitted by the sun are filled in the space of the solar system, and interact with the earth's magnetosphere and power layer to affect the space of human activities, especially if human activities are in space < p > in the past, astronomical observation on the ground was through the naked eye or telescope. After entering space, human beings completely opened the electromagnetic spectrum blocked by the earth's atmosphere, that is, human beings opened the window and mysterious veil of astronomical observation. Therefore, from gamma rays to infrared rays with lower energy, all electromagnetic spectral bands can be observed in space. Therefore, it has opened up an era of full spectrum, such as all electromagnetic wave astronomy, particle astronomy, gravitational wave astronomy and neutrino astronomy. For example, the observation of the cosmic background strongly supports the framework of the "Big Bang" theory, which is a major breakthrough in the emergence and evolution of the universe < p > this is the strong gravitational lens phenomenon seen by Hubble telescope. It is a very good proof of general relativity and light bending. At present, it is used as a very important tool to observe and study the distribution of dark matter in the universe. This is the next generation space telescope that may be launched at the end of December. Its mirror has a diameter of 6.5 meters. It will make further exploration on the formation and changes of the early universe and cutting-edge scientific issues, including extraterrestrial planets < p > planetary science we all know that there are important questions about the moon, Mars, the existence of water on Mars, etc ?
