Why did the successful launch of Fat Five cause such a big sensation? Does it have any special meaning?

The launch of the Long March 5 is of great significance and caused a huge sensation, because this is when our country was under tremendous pressure after the failure of the second launch of the Long March 5 rocket and made complete preparations. my country's first heavy-lift launch vehicle was launched again.

The Long March 5 Yaosan launch vehicle has a maximum take-off weight of 870 tons and a maximum thrust of 1,000 tons. It has entered the ranks of large rockets in the world, surpassing Japan's H-2B launch vehicle and Europe's Alia. The Na-5 launch vehicle and Russia's Angara launch vehicle have made breakthroughs in hydrogen-oxygen engine and ice rocket technology in one fell swoop. They can send 25 tons of weight to the earth's low-Earth orbit and 14 tons of payload to the geosynchronous orbit. They have strong carrying capacity. It can provide support for my country’s future large-scale space construction.

In addition to its strong carrying capacity and the ability to deploy large-scale space facilities in low-Earth orbit, the Long March 5 Yaosan rocket can also deliver deep space probes to orbit around the sun or directly launch them out of the solar system. This It has very extraordinary significance for our country to carry out deep space exploration

Now it is different. We have a launch vehicle that is much more powerful than H2B. With the Long March 5 Yao-3 launch vehicle, our country has taken advantage of the trend to make a breakthrough. The bottleneck of large rocket R&D and manufacturing can not only carry out deep space exploration, but also take advantage of the situation and use the Long March 5 technology to develop the Long March 9 ultra-large rocket that is proportionally enlarged and added with new materials and new technologies, achieving a maximum thrust of With a capacity of 5,000 tons, the Long March 9 rocket will be the largest rocket in the world with the largest thrust and the best performance in the world.

It can be said that the Long March 5 Yaosan rocket has made my country's launch vehicle technology enter the top three in the world, second only to the United States and Russia. The United States and Russia have now launched super large rockets with a thrust of more than 3,000 tons. The US Saturn 5 has a maximum thrust of 4,000 tons, and the Russian N1 rocket has a maximum thrust of 4,600 tons. These super huge rockets and their technology are very advanced. It is the result of the direct competition between the United States and the Soviet Union in the Cold War. It is the product of the superpower's national effort to develop. Of course, its launch failure rate is high, and it has now been retired.

After the Long March 9 appears, it will not only surpass these two rockets in terms of thrust, but will also be safer, and its material technology and processing accuracy will be improved by several levels. At the same time, another significant significance of the successful launch of the Long March 5 Yaosan rocket lies in its satellite, which is the Shijian-20 satellite. This is an 8.6-ton satellite and a new generation satellite platform in our country. In fact, the value of the Shijian-20 satellite is even greater than that of the Long March-5 Yaosan-3 rocket. It is currently the heaviest and most advanced satellite platform in the world.

The deployment length of its cross-shaped solar panels can reach 40 meters. The Shijian-20 satellite has the characteristics of autonomous precise orbit change, over 10G bandwidth communication, laser communication, strong power, and high cooling performance. The platform can be used as a communication satellite, or it can be equipped with different payload equipment to become other satellites, such as experimental satellites, return satellites, reconnaissance satellites, ocean surveillance satellites, optical satellites, space search satellites, navigation satellites, etc. You can imagine it It becomes a large truck with abundant energy and quick connection with the ground. You can install different equipment on it to achieve different functions. After the satellite is successfully tested, our country will rely on it to build the most advanced and powerful satellite in the world. satellite system.

The Long March 5 Yaosan 20 satellite has opened a new era for our country’s aerospace industry. We should be proud of this. This is because our country has long blocked rocket technology and satellites from us in the United States, Russia, Europe and other space powers. In terms of technology, compared with Europe and Japan that rely on American technology to successfully develop rockets, my country's independent research and development is more difficult, but its achievements are higher. This has created a young and promising aerospace industry. R&D and manufacturing teams, they are a valuable asset for our country to move towards the stars and the sea.
