Why not launch a space rocket on the Qinghai-Tibet Plateau at an altitude of more than 5,000 meters?

The height of several kilometers is of little practical significance to rocket launch. The main purpose of building a space city is to facilitate transportation and so on? It is more difficult to build the Qinghai-Tibet Plateau.

Basic conditions of the rocket launching area: firstly, the terrain should be broad and flat, without dense forests, so as to reduce the impact of birds on the spacecraft, thus bringing unnecessary troubles, convenient transportation, shortening the transportation time, improving the effectiveness, good climate and less abnormal weather, thus reducing the number of buildings around the launch problem, and basically no tall buildings, so as to reduce casualties and economic losses caused by spacecraft accidents.

The location should be far from densely populated areas such as cities, and the climate should be dry and rainy. It is better for the base to be near the low latitude. In addition to secret launch, it is best to choose during the day to facilitate the search after the accident, especially for manned vehicles, and it is also best to return during the day to facilitate search and rescue. In addition, consider the weather.

The launch time of buildings with uneven surroundings cannot be clearly determined, because a little error in launch time will prevent the rocket from entering the original orbit! You know, the earth has been spinning. Latitude should be low, so the rotation speed is high and the speed required for rocket launch is low. The community should be empty and have a broad view. The climate is clear and the clouds are thin. Convenient transportation is beneficial to the transportation of rockets.

Space and military are closely related to national defense, and the safety of the launch site itself naturally ranks first. Most space launch sites have traces of intercontinental missile experimental bases, and the site selection has many military purposes.
