"Crystal News" full page report: the infinite mystery of space technology exploration

In order to carry forward the humanistic spirit, develop public culture, enrich citizens' life, improve urban taste and continuously expand the brand influence of the campus, following the brand activity of "famous teachers of Harbin Institute of technology entering Shenzhen high school classroom", Harbin Institute of Technology (Shenzhen) cooperated with the Publicity Department of Shenzhen Municipal Party committee to carry out the brand activity of "famous teachers of Harbin Institute of technology entering Shenzhen civic culture lecture hall".

As the first famous teacher of the brand activity, on May 14, Wei FengSi, the academician of the Chinese Academy of Sciences and the president of the Academy of space science and applied technology of the campus, visited the public culture lecture hall and gave a wonderful lecture entitled "invisible killer: space weather you don't know". Different from the previous lectures, the audience of this lecture included not only elder people with gray hair, but also vigorous young generation. All of them exchanged dialogues with academicians, and the atmosphere of the lecture was warm.

So, what is space weather? Let's hear what the academicians say.

Space weather: invisible killer you don't know

"Generally speaking, space weather is the phenomenon of ‘storm’, ‘thunder and lightning’ between 20-30km away from the earth's surface to the solar atmosphere." Wei FengSi said in the lecture that space weather science is a new frontier interdisciplinary science. Its concept is developed on the basis of analogy of "earth weather". What it studies is the sudden storm time changing phenomenon of electromagnetic environment, particle environment and atmospheric environment in the solar terrestrial space environment.

"Space weather science is also a strategic science related to the survival and development security of human society. From national security and economic and social operation to people's daily communication and financial activities, space weather is closely related. According to the official website of popular science on August 10, 2016, as early as 1967, due to the influence of solar storm, a common space disastrous weather, all radars of the three ballistic missile early warning systems deployed by the United States in the high latitude region of the northern hemisphere were completely interrupted. The US military suspected that the Soviet Union at that time deliberately interfered with the US radar equipment. " "Fortunately, space weather forecasters timely reported that the event was caused by solar storms rather than human factors, thus avoiding a possible nuclear war between the United States and the Soviet Union," Wei said Wei FengSi said.

In October 2003, there was also a space disastrous weather event. In this event, there were global short wave communication interruption, over the horizon radar, civil aviation communication, satellite, navigation and other failures, which led to the national power grid interruption of Sweden for one hour, the loss of Japanese reconnaissance satellites, and the impact on the communication between the United States and Britain in Iraq Academician Wei FengSi said that according to statistics, major space disastrous weather events occur almost every year, which directly affect our human life. It is a great challenge for us to reduce or avoid the possible serious damage caused by space disastrous weather. At present, space weather science has also become the commanding height of various countries.

China and the United States will become the leaders of space weather in the eastern and western hemispheres

Since the 1990s, countries all over the world have formulated national space weather start-up plans. The European Space Agency (ESA) and NASA of the United States have been paying close attention to space weather changes. The United Nations and the World Meteorological Organization (WMO) have successively supported research programs in the field of space weather and coordinated global space weather monitoring and research activities.

In October last year, President Barack Obama issued a presidential decree "all ministries and commissions work together to improve the national capacity to cope with space weather events", which showed that the United States attaches great importance to the development of space weather as a national behavior of national decision-making, and also indicates the beginning of a new round of space weather development.

"To our delight, China's space weather science is on the road of leapfrog development. The international community pays close attention to the development of China's space science. During the 13th Five Year Plan period, the "space environment ground-based monitoring network" (the second phase of the meridian project) has become one of the ten national major science and technology infrastructure construction projects, and the space-based satellite program for space weather monitoring and early warning is also being launched. The international space weather meridian plan led by China has been implemented; China's national space weather monitoring and early warning center and the United States space weather forecasting center have become the co chairman of the international coordination group on space weather of the World Meteorological Organization (WMO). China's space weather forecasting capability has begun to make contributions to China's major space activities, such as when the Shenzhou-7 astronauts leave the capsule "The inter prediction error is only one minute; the failure of China's communication satellites is predicted a few days in advance; the radiation safety warning is provided for the trans polar flight of civil aviation of China; the efficiency of the most advanced short wave communication system is increased by 45%," Wei FengSi said.

Shenzhen will become a new space science and technology center in South China

"The space environment foundation monitoring network (the second phase of the meridian project) proposed the construction of a" two vertical and two horizontal "network layout, with Shenzhen as a key area for monitoring. The Shenzhen municipal government has paid close attention to it and is building Shenzhen into a new space science and technology center in southern China through the implementation of the "infrastructure of Shenzhen low latitude space environment monitoring station". In April this year, Wei FengSi was officially appointed as the president of the campus space science and Application Technology Research Institute, which is expected to be officially established in late June this year, with nine laboratories under it. One belt, one road, will be built in the south of Shenzhen. We will make contributions to the development of the new space technology center in southern China through the construction of the space science and Applied Technology Research Institute, serving the communications and navigation, financial services, telemedicine, digital city, the all side guarantee, and the economic and social development of the ecological environment and fishery production. Wei FengSi said in the lecture.

"As a frontier city of reform and opening up, Shenzhen's economic development rate is in the forefront of large and medium-sized cities in China. In the construction of the Institute of space science and applied technology, we will also fully carry forward the spirit of "daring to be the first in the world" of Shenzhen, and promote the construction of Shenzhen into a new space science and technology center in southern China with the help of the whole country. At present, the Institute is looking forward to all sectors of the society, recruiting cooperation units and outstanding talents. We hope that people with lofty ideals will join us in building Shenzhen into a new space science and technology center in southern China. "Wei FengSi said.

Ensuring communication, safe travel and leading development: space technology is closely related to citizens

What are the benefits to Shenzhen citizens when Shenzhen becomes a new space science and technology center in southern China? What benefits can Shenzhen citizens feel and enjoy? Wei FengSi said that he came to Harbin Institute of Technology (Shenzhen) to take the lead in setting up the Institute of space science and applied technology to build Shenzhen into a new space science and technology center in southern China. His purpose was to explore the feasibility of using space science and technology to open up space science and technology and promote the faster and better economic and social development in Shenzhen.

Popularly speaking, one can provide protection for one belt, one road and another, and the other is to provide a guarantee for the South China Sea fishing, especially the "one belt and one road". When it comes to daily travel, if your flight passes through the polar region, you must check in advance whether the space weather is suitable for travel; if you are engaged in the financial industry, the sudden interruption of communication caused by space weather disasters will also have an impact on your control of stock and securities trading information. "Wei FengSi said.

"Shenzhen's becoming a new center of space science and technology in southern China means that Shenzhen will become a monitoring center for low latitude space environment in the south, a center for space weather forecasting in the south, a monitoring and Analysis Center for low-level air pollution in the south, etc., which involves solving the problems of haze and air pollution, which is also related to the health and safety of Shenzhen citizens." Wei FengSi said that in the future, the Institute of space science and applied technology led by him will also actively explore how to use space science and technology to open up new areas of strategic economy in Shenzhen's peaceful use of space, such as low orbit navigation, space solar energy utilization and quantum lidar detection technology, so as to lead the new development of space science and technology in the south.

It is reported that the Academy of space science and applied technology and the University of science and technology of China are actively exploring how to use quantum lidar detection technology to provide necessary monitoring means for air quality forecast and air pollution analysis in view of the current serious air pollution problems such as haze and smog in China, so as to monitor the composition, distribution and concentration of sulfur dioxide, haze and other air pollutants monitor. Shenzhen will become a new generation of lidar test base for atmospheric environmental monitoring in China, and promote the industrialization of this technology, which will be widely used in Meteorological Bureau and Environmental Protection Bureau, laying the foundation and making contributions to major livelihood projects such as air pollution control and haze elimination in China.
