China will build a new space launch site in Wenchang, Hainan, and analyze its advantages and disadvantages.

The purpose of building a new space launch site is to adapt to the sustainable development strategy of China's space industry and meet the launch needs of a new generation of non-toxic and pollution-free launch vehicles and new spacecraft. Advantages: Hainan's new launch site faces the sea, which not only has good maritime traffic conditions, but also has good safety in the rocket navigation area and debris landing area. First of all, Hainan is the land area with the lowest latitude in China. The satellite has small launching angle, high launching efficiency, low cost and low technical difficulty, which can prolong the service life of the satellite. When launching a geosynchronous satellite in Hainan, compared with Xichang, the carrying capacity of the rocket can be increased by 10% to 15%, the fuel consumed by the satellite can be saved by about 100 kg, and the service life of the satellite can be extended by more than two years. Secondly, geosynchronous orbit, sun-synchronous orbit and near-earth orbit satellites can be launched in many directions and in a large range; Third, it is convenient to transport. Large launch vehicles can be transported by ship, and the diameter of the transported rockets is not limited. Fourth, the security is good. The landing areas of large launch vehicles are all oceans and there is no land pollution. Launching geostationary orbit satellites into densely populated areas; Fifth, Hainan has a beautiful natural environment, and energy, transportation and communication all have the conditions to build a space launch site, which can provide strong logistical support; Sixth, the existing launch base is limited by geographical conditions and other factors, so it cannot be comprehensively developed and utilized. If it is built in Hainan, it can not only be used for commercial launch, but also greatly promote the development of tourism in Hainan.
