On December 30, 2002 (November 27, 2002 lunar calendar), our country successfully launched the "Shenzhou" IV spacecraft. The "Shenzhou" IV unmanned spacecraft was successfully launched by the Long March 2F carrier rocket at Jiuquan Satellite Launch Center. In the early morning of December 30, 2002 Beijing time, the "Shenzhou" IV unmanned spacecraft was launched by the Long March 2F carrier rocket at Jiuquan Satellite Launch Center. In the early morning of December 30, 2002 Beijing time, our country's self-developed "Shenzhou" IV unmanned spacecraft was launched at Jiuquan Satellite Launch Center and successfully entered the predetermined orbit. This is the fourth flight test of our country's manned space project. Li Peng, Chairperson of the Standing Committee of the National People's Congress, Wu Bangguo, Vice Premier of the Political Bureau of the CPC Central Committee, and Jia Qinglin, Member of the Standing Committee of the Political Bureau of the CPC Central Committee, watched the launch of the spacecraft at the launch site. In the early morning of the 30th, the starry sky at the manned space launch site was brilliant. Next to the launch tower of the spacecraft, which was more than 100 meters high, stood the Long March 2F bundled large-thrust carrier rocket. The word "Shenarrow" written by Comrade Jiang Zemin on the arrow body was particularly eye-catching, and the top of the rocket held the "Shenzhou" IV spacecraft. At 0:40, with a loud bang in the sky, the rocket took off and flew into space at high speed. The long flames ejected from the tail of the rocket drew a gorgeous rainbow in the night sky. After more than ten minutes, the spacecraft successfully entered the predetermined orbit. The successful launch of this spacecraft marks a new progress in our country's manned spaceflight industry and another important step towards the realization of manned flight. After the successful launch of the spacecraft, Li Peng delivered an important speech. He said that we have experienced an exciting moment together, and the world-renowned "Shenzhou" IV spacecraft has been successfully lifted into the air. This is a great event to raise the national ambition and strengthen the national prestige and military prestige, and the whole country is proud of it and excited. On behalf of Wu Bangguo, Jia Qinglin, Cao Gangchuan, Song Jian and other leading comrades, I would like to extend my warm congratulations and sincere greetings to all the scientific and technological personnel, cadres, workers and PLA commanders and fighters who participated in the research and test of the manned spaceflight project. Li Peng pointed out that the success of this launch is of great significance in the nine months since the successful launch of the Shenzhou-3 spacecraft under the excellent situation of the whole Party, the whole army and the whole people earnestly studying and implementing the spirit of the 16th National Congress of the Communist Party of China and creating a new situation in high spirits. This is the result of the scientific decision-making and correct leadership of the Party Central Committee, and the result of unity, cooperation and hard work of all the test participants. The successful launch marks the maturity of our country's manned space technology, marks the significant improvement of our country's comprehensive national strength and scientific and technological strength, and fully demonstrates the strong confidence of the Chinese people to achieve national rejuvenation as one. The success of this launch is not only a huge boost to the development of our country's manned spaceflight project, but also a huge encouragement to all fronts across the country. Practice has once again proved that the decision of the Party Central Committee to make up its mind to engage in manned spaceflight is very correct. We must unswervingly follow the established goals and make due contributions to the development and utilization of space for mankind. Li Peng stressed that the 16th National Congress of the Communist Party of China has established new goals for our country's development and drawn a new grand blueprint. Manned spaceflight project is a key project of the country. Vigorously promoting this key project and breaking through and developing our country's manned spaceflight technology is of great significance and far-reaching impact on building a moderately prosperous society in an all-round way and advancing the great cause of socialism with Chinese characteristics. The comrades who work on this front are most honored. The hard work and sweat you have put in will never be forgotten by the party and the people. Your achievements will be recorded in the annals of history forever. The follow-up tasks of the manned space project are still very heavy. All comrades who hope to participate in the research and development test should earnestly study and implement the spirit of the 16th National Congress of the Communist Party of China, fully implement the important thought of "Three Represents", vigorously carry forward the spirit of "two bombs and one star", maintain and carry forward the fine tradition and tenacious style of the space front, make persistent efforts, take advantage of the momentum, work solidly and meticulously, adhere to quality first, ensure the complete success of the manned flight test, and make greater contributions to the realization of the flying dream of the Chinese nation and the realization of the goals set forth by the 16th National Congress. Before the launch of the Shenzhou IV spacecraft, Li Peng, Wu Bangguo, and Jia Qinglin also listened to the work report of Li Jinai, the chief commander of the manned spaceflight project, and inspected the front-line headquarters of the spacecraft launch, the command and control hall, the vertical assembly test plant of the rocket spacecraft and the manned space launch site. They met with the participants and shook hands with everyone. Our country successfully launched the Shenzhou spacecraft for the first time on November 20, 1999. According to the development plan, several unmanned spacecraft will be launched, and then manned flights will be carried out. The Shenzhou IV spacecraft launched this time is an important flight test in the entire development plan. The spacecraft will return to the ground after completing the scheduled test mission in space. " The Shenzhou-4 spacecraft is mainly developed by the China Academy of Space Technology and the Shanghai Academy of Aerospace Technology, which are affiliated to the China Aerospace Science and Technology group company; the Long March-2F rocket is developed by the China Academy of Launch Vehicle Technology, which is affiliated to the China Aerospace Science and Technology group company. The relevant units of the Chinese Academy of Sciences, the Ministry of Information Industry and other departments have developed shipborne instruments and ground measurement and control equipment for space science experiments and application research. The whole system of manned space application system will participate in the test. During the autonomous flight and orbit retention flight of the spacecraft in space, the multi-modal microwave remote sensor will be used for ground detection, comprehensive precision orbit determination test, space separation and purification experiment of biological macromolecules and cells, and microgravity fluid physics experiment. The astronaut system and the spacecraft's environmental control and life support subsystems also fully participated in the test. Previously, the prepared astronauts had entered the spacecraft for practical experience. In accordance with the requirements of the official manned flight, a number of emergency rescue zones on land and emergency rescue zones at sea were set up, and rescue personnel were in place and conducted relevant drills. During the orbital flight of the spacecraft, under the unified dispatch of the Beijing Aerospace Command and Control Center, the relevant measurement and control stations and the "Yuanwang" ocean space survey ship will continuously track, measure and control the spacecraft. The launch of the "Shenzhou" 4 spacecraft is the 69th flight of the Long March series of carrier rockets, and it is also the 27th consecutive successful space launch of our country since October 1996. The launch site of the spacecraft - Jiuquan Satellite Launch Center, has a complete launch measurement, control, communication, command system and equipment and facilities to meet the needs of astronauts, as well as a backup landing site and an emergency life-saving medical center.
