What are the advantages of Wenchang Satellite Launch Center?

The advantages and disadvantages of space bases are generally analyzed from these angles.

Latitude position 1:

The latitude of Wenchang is as large as the north latitude19 20' to 2010'. This latitude position is the lowest dimension among the three satellite launch bases built in China. Launching a satellite here will help the spacecraft to obtain a larger initial velocity, thus saving fuel and carrying a larger satellite or experimental equipment.

I think this is also the fundamental reason for choosing Wenchang. In the past, the satellites and spacecraft we launched were not too big, so there was no more fuel at the high point of Jiuquan dimension. But next, China will go into space, prepare to land on the moon, and prepare to build a large space station. These spaceships are very large, so it is very important for the rocket to get a large initial velocity at the beginning of launch.

2 climatic conditions

Generally speaking, dry climate, scarce precipitation, clear weather and high atmospheric visibility are all conducive to rocket launch.

Wenchang is located in the northeast of Hainan Province, with a tropical monsoon climate and abundant rainfall. Annual rainfall1721.6mm, with an average of1529.8 ~1948.6mm. ..

Strictly speaking, this climate is not conducive to rocket launch.

But the rainy season is relatively concentrated. The rainy season is mainly concentrated in the flood season from May to 65438+ 10, and the rainfall accounts for 80% of the whole year.

Maybe the country mainly considers launching rockets in the dry season.

But worst of all, Wenchang City is surrounded by the sea on three sides, which is one of the areas most seriously affected by the landing typhoon in China. From August to165438+10 every year, our city is often affected by strong tropical storms and typhoons, with an average of 2.6 typhoons every year.

I wonder what preventive measures the country has. If it is not solved well, the problem will be very serious.

The Kennedy Space Center is located on the east coast of Florida, close to Wenchang. In September 2004, part of the Kennedy Space Center was destroyed by Hurricane Francis. In the south and east of the aircraft assembly building, more than 10001.2x3m tiles were uncovered, exposing the entire 3,700-square-meter building. The production workshop of the space shuttle insulation tile was also damaged, with some roofs exposed and the interior seriously damaged by water.

In addition, in April 2008, Typhoon Raccoon landed in Hainan, and the landing place was Wenchang.

3 Terrain conditions

Wenchang, located in the northeast of Hainan, belongs to the low hilly platform plain. Hainan's terrain is relatively flat. If we consider the Taiyuan Satellite Launch Base (near Luya Mountain) and Xichang Satellite Launch Base (the hinterland of Daliangshan Mountain) in China, the terrain conditions of Wenchang are very good.

This is also an advantage of Wenchang.

4 traffic location

Wenchang is surrounded by the sea on three sides, which is convenient for transporting large rockets and aviation equipment by sea, with low population density and safer launch.

The traffic location near the sea is another great advantage of Wenchang besides its low dimension. It is also an important reason for its goal.

In addition, Wenchang coastal area is rich in precipitation and water resources, which is also an advantage.

The above is my analysis. As an armchair geography teacher, I am very worried about the climatic conditions for the country to build a space base in Wenchang. But then again, the world-famous space cities are all built in low dimensions. In addition to the Kennedy Space Center, the European Space Launch Center is located in French Guiana, which is located on the Atlantic coast of northern South America, near the equator, between 528 west longitude and 2 ~ 6 north latitude.

The spacecraft is getting bigger and heavier, so it is not unrelated to get a larger initial launch speed.

Well, it seems that climate is not the main factor in building a space launch center.
