What is the information about the Long March 5 rocket?

The Long March 5 rocket is the first new generation of large launch vehicle developed by my country.

The Long March 5 carrier rocket (hereinafter referred to as the Long March 5) is affectionately called the "big rocket" by astronauts. His specific information includes: The Long March 5 is about 57 meters tall, 20 stories high, with a rocket body diameter of 5 meters and a take-off mass of 870 tons. It is the tallest and largest rocket in my country. The rocket is equipped with three new high-thrust engines, which respectively won the three crowns of my country's "largest thrust liquid oxygen kerosene engine", "largest thrust hydrogen oxygen engine" and "rocket engine with the highest specific impulse performance".

The Long March 5 rocket is not only big, but also powerful. Li Dong, chief designer of the Long March 5 rocket of the China Aerospace Science and Technology Corporation, said that the Long March 5 has made breakthroughs in a series of key core technologies such as high-power hydrogen and oxygen engines. Its take-off thrust has exceeded 1,000 tons, and its carrying capacity in low-Earth orbit has reached 25 tons. , the carrying capacity is more than 2.5 times higher than that of the current Long March 3A series rockets, making it the rocket with the strongest carrying capacity in China.

The significance of the "Long March 5"

The successful first flight of the Long March 5 marks that our country has entered the ranks of large-tonnage rocket launches in the world, and will significantly enhance our country's access to space. capabilities and promote a historic leap in comprehensive space launch capabilities, which is an important cornerstone for my country to move from a major space country to a powerful space country. The Long March 5 is a milestone project for the upgrading and upgrading of my country's launch vehicles. It has many innovation difficulties, a large technological span and a high degree of complexity. It represents the highest level of scientific and technological innovation of my country's launch vehicles.

The technological level of launch vehicles not only represents a country’s ability to independently enter space, but also reflects its ability and level to ultimately utilize space and develop space technology. It is the foundation of a country’s aerospace capabilities.

In recent years, other aerospace powers have been developing large rockets and even heavy rockets, establishing the development of advanced space launch technology as an important national strategy. However, the maximum carrying capacity of the Long March series of rockets currently in service in my country is only It is a 5-ton class. To further carry out deep space exploration in the future, we must develop high-thrust launch vehicles. This is an inevitable requirement for the development of space technology.
