1. Self reliance and self-improvement, deep space exploration goes further. "Chang'e" surveys the moon, "Zhurong" explores fire, "Xihe" organizes a network day by day, "Beidou" organizes a network, and "Tianhe" travels through the stars... We are going farther and farther in the vast starry sky. Since the 18th National Congress of the Communist Party of China (CPC), facing the major needs of the country, focusing on strategic directions and key areas, the major national science and technology projects and major projects in the space field have made a series of major achievements, constantly refreshing China's height of climbing the space science and technology peak. Chang'e-3 achieved the soft landing of Chinese spacecraft on extraterrestrial objects for the first time, Chang'e-4 achieved the soft landing and patrol detection of human spacecraft on the back of the moon for the first time, and Chang'e-5 achieved the sampling and return of Chinese extraterrestrial objects for the first time; The first Mars exploration mission of Tianwen I achieved the goal of "circling, landing and patrolling" once, and successfully achieved the leap from Earth Moon system to interplanetary exploration in China's deep space exploration; "Xihe" made our country enter the era of "exploring Japan" formally, and the exploration achievements in only one year created five international "firsts"; "Wukong", "Huiyan" and other scientific satellites have made major scientific discoveries in the fields of dark matter particle detection, black hole and astronomical observation; The construction of the high-resolution Earth observation system was completed as scheduled, forming a global observation capability with high temporal resolution, high spatial resolution and high spectral resolution; The Beidou-3 global satellite navigation system has been fully completed and put into service. China has become the third country in the world to independently own a global satellite navigation system; ... In the past ten years, the innovative achievements made by China's aerospace industry have greatly encouraged the innovation enthusiasm of the people all over the country, and the world has seen China's determination to become self reliant, self reliant and committed to high-level independent innovation. (On June 23, 2020, the last networking satellite of China's Beidou-3 global satellite navigation system was launched.) 2. Manned space flight, the "space home" has become a reality, which is a day recorded in China's space history. On June 5, 2022, with the successful launch of the Shenzhou XIV manned spacecraft, astronauts Liu Yang, Chen Dong and Cai Xuzhe entered the Tianhe core module, and the mission of the Chinese space station turned to the construction stage in an all-round way. The dream of building a "space home" for Chinese people is becoming a reality step by step. Manned space flight is a concentrated reflection of the development level of high-tech in the world, and also an important symbol to measure a country's comprehensive national strength. In the past decade, China's key technologies in manned spaceflight have been continuously broken through, and the construction of "Space Homeland" has been steadily promoted. In June 2013, astronauts Nie Haisheng, Zhang Xiaoguang, and Wang Yaping took Shenzhou 10 spaceship into space, completed one automatic and one manual docking, conducted space teaching, and successfully completed the first practical flight of China's manned space shuttle transportation system; On November 18, 2016, astronauts Jing Haipeng and Chen Dong completed their 33 day mid-term stay in space, laying a more solid foundation for the subsequent construction and operation of China's space station; On April 20, 2017, China's first cargo spaceship, Tianzhou-1, was launched and completed the first "space refueling" with the Tiangong-2 space laboratory in orbit. China became the third country in the world to independently master this key technology. Since 2020, China has successfully implemented the Long March
