How to locate the satellite launch base and what is the satellite launch site related to?

* * * * Longlou Town, Wenchang, Hainan, China-Space Launch Site * * * the State Council and the Central Military Commission approved the construction of a new space launch site in Wenchang, Hainan Province on 2 1. According to the analysis of space experts, following Jiuquan, Xichang and Taiyuan, China will build a coastal launch base, which will greatly meet the new needs of China's space development. The launch site built in Hainan, on the one hand, is closest to the equator, which can greatly reduce fuel consumption; The thrust of the same type of rocket can be increased by 10%. On the other hand, it can also solve the problem of shipping such a huge rocket, and greatly improve the safety of wreckage falling. According to CCTV, the construction of the new space launch site conforms to the sustainable development strategy of China's space industry and meets the launch needs of a new generation of non-toxic and pollution-free launch vehicles and new spacecraft. After the completion of the new space launch site, it will mainly undertake the launching tasks of spacecraft such as geosynchronous orbit satellites, large-mass polar orbit satellites, large-tonnage space stations and deep space exploration satellites. Make up for the shortage of inland bases According to the analysis of aerospace experts, there are currently three major space launch bases in China, Jiuquan, Xichang and Taiyuan, but they all go deep inland, which has caused many troubles that are not conducive to the launch of new spacecraft. The completion of Hainan space launch base will make up for these shortcomings. First of all, due to the limitation of the current diameter of China Railway Tunnel, rockets and engines with a diameter of more than 3.5 meters cannot be transported by railway. At present, Jiuquan, Xichang and Taiyuan satellite launch centers are all inland, so new rockets with a diameter of 5 meters will not be able to reach these locations for launch. Wenchang is located in the coastal area, and the adjacent Qinglan Port is one of the five major hub ports in Hainan Province, which can berth 5,000-ton ships and accommodate ro-ro ships loaded with large rockets with a little modification. Secondly, the rocket booster and the first-class arrow are thrown away after work, and these wrecks generally fall within 1000 km east of the launch point. Within the range of 1 1,000 km east of Hainan launch site, almost all of them are in the South China Sea, with only a few scattered islands, which greatly improves the safety of debris falling. The second best location in the world. Finally, the latitudes of the three launch centers are relatively high. Geographically, Hainan is the closest province to the equator in China. For example, when launching a geosynchronous orbit satellite, the orbit is close, the satellite can reach the predetermined orbit with less energy consumption, and can make full use of the energy of the earth's rotation, thus saving the energy of the satellite and prolonging its operating life. The latitude of Wenchang in Hainan is about19 30 ". If completed, it will become the second best launch site in the world. The new space launch site and its supporting Wenchang Space City cover an area of 20 square kilometers, including a series of projects such as space launch site, space theme park, rocket assembly plant and command center. Local officials said that in 2002, the national expert group conducted a site selection demonstration for the space launch base, and in 2005, it was officially determined that the site was located in Longlou Town, Wenchang. Wenchang Longlou Town covers an area of 98 square kilometers and has a total population of more than 20,000. The population is relatively sparse, the terrain is flat and open, and the geological structure of granite is stable. The reporter called the relevant person in charge of Wenchang Municipal Government today. The other party said that it had been informed of the news before, and said that the city had held a meeting to make arrangements and would fully cooperate with relevant parties in the country and the province to do a good job in the construction of the space launch site project. According to sources, the total investment of the space launch site project may exceed 20 billion yuan, and the supporting infrastructure includes the construction of bridges and high-grade highways. The first batch of more than 20,000 scientific and technical personnel and their families will immigrate to Hainan, and their living base will be located along the Nandu River in Guilin, near Haikou City. Schools, hospitals, supermarkets and other life-related supporting facilities will be built, with the target scale of building an area that can accommodate 50,000 people. According to the safety factors, the residents of Longlou Town will move to the resettlement area 10 km away from the space launch base. It is also known that Wenchang also plans to build a space theme park, making Wenchang Space Launch Base a comprehensive project to promote Hainan's economic and social development, especially the development of tourism. Xie Mingzhong, secretary of Wenchang Municipal Party Committee, also said that the ticket to visit the satellite launch base is tentatively set as 500 yuan.
