Today (April 24) is China Space Day and the 52nd anniversary of the successful launch of dongfanghong I, the mainland's first artificial earth satellite. On April 24, 1970, the mainland's first artificial satellite "Dongfanghong I" was successfully launched, and a song "Dongfanghong" resounded throughout the world, announcing that the mainland has since entered the space age.
In recent years, with the increasing number of various types of satellites and spacecraft with different functions, the space debris generated has put forward higher requirements for the orbital planning and operation of subsequent launch missions. Therefore, in order to make better use of space space, the mainland will build a perfect asteroid monitoring and early warning system to ensure the safe, stable and orderly operation of spacecraft in space.
Wu Yanhua, deputy director of the China National Space Administration, said in an exclusive interview with a CCTV reporter recently that the mainland will begin to set up a near-Earth asteroid defense system to jointly deal with the threat of near-Earth asteroid impacts and contribute China's strength to protecting the security of the earth and mankind.
Wu Yanhua, deputy director of the China National Space Administration: We must begin to improve the establishment of a ground-based space-based monitoring and early warning system for asteroids. In this way, we must not only catalog, but also the key is to analyze which ones are critically endangered to make a judgment. The second is to study and explore related technologies and engineering, whether it is possible to eliminate these threats, we must carry out relevant technical research and research.
At the same time, the mainland will also start to set up a near-Earth asteroid defense system, organize the preparation of a near-Earth asteroid defense development plan, develop a near-Earth asteroid defense simulation and deduction software, and organize the basic process deduction.
Wu Yanhua, Deputy Director of the China National Space Administration: We strive to implement a threatening asteroid at the end of the "14th Five-Year Plan" or in 2025 and 2026, not only to observe the proximity, but also to implement the nearest impact, and to change its orbit for technical experiments, so that for our future human beings to truly deal with the threat of asteroid extraterrestrial objects to the earth's homeland, and truly make our new contribution to China.
Planetary Exploration Engineering The next step is to start asteroid exploration
Today is China Space Day, Wu Yanhua, deputy director of the China National Space Administration, said in an exclusive interview with a CCTV reporter recently that after the successful completion of the first Mars exploration mission of Tianwen-1, the next step of the planetary exploration project will begin the exploration of asteroids. Chinese the pace of exploring the universe will go even further.
Wu Yanhua, deputy director of the China National Space Administration: The state has approved the planetary exploration project, which includes the first Mars exploration mission of Tianwen-1, and also includes the next asteroid exploration, including such a detection mission that we return from sampling. Third, we will carry out a sample return to Mars. The fourth is the detection of Jupiter galaxies, and some detections through the universe.
Wu Yanhua said that the planetary exploration project is planned to be completed in the next 10 to 15 years. In addition, at present, the mainland is still carrying out the demonstration of medium- and long-term strategic planning, such as the exploration of the margin of the solar system. Facing deeper and farther space, multi-type launch vehicles, including heavy rockets, are also in the development stage and are expected to complete their first flights in the next few years.
Wu Yanhua, deputy director of the China National Space Administration: How big the carrying capacity is, how wide the space stage can be expanded. Heavy carrying we are a common name, in fact, refers to the low-Earth orbit capability in the 100-ton level, it includes a capacity of between 50 tons and 150 tons, it will also be a spectrum planning.
Wu Yanhua said that the heavy carrier rocket will meet the mainland's long-term deep space exploration and manned lunar landing and other major space missions in the future.
Wu Yanhua, deputy director of the China National Space Administration: For example, we are also arguing whether to engage in manned lunar landing, whether we should launch large space solar power plants, for example, whether we should launch larger exploration equipment on Mars, including exploration vehicles.
