The picture shows the genealogy of the development of the Long March 9
Recently, the network circulated the production of China's new heavy rocket engine and the first engineering prototype, marking the successful completion of the "key technology research and demonstration stage research and development work" of the rocket engine. And China also recently announced, the latest appearance of the Long March 9 rocket, and the previous appearance is very different, the Long March 9 is at a gradual speed, to help China complete the grand blueprint of space, the Long March 9 two types of power have been unveiled, where to go from the light rod version of the advanced configuration? In fact, China has long planned, after the United States refused to cooperate with China, the Long March 9 rocket broke through overnight, the United States heard the news: regret the intestines, this Long March 9 new debut 2 kinds of engines, more advanced light rod version is not used, why is this?

The Long March 9 is China's new generation of heavy carrier rockets, in 2010 began to discuss China's new generation of heavy carrier rockets, in 2013, Tan Yonghua, president of the Sixth Academy of Aerospace Science and Technology Group, published a paper in the Journal of Astronautics, officially set the performance data of the Long March 9 heavy carrier rocket. Long March 9 is prepared for China's deep space exploration, landing on the moon and landing on the moon, China's future construction of new space stations and other tasks, the long march 9 core stage maximum diameter of 10 meters, the maximum take-off mass of 4137 tons, low-Earth orbit carrying capacity of 150 tons, the earth transfer orbit of 53 tons, in terms of take-off weight and carrying capacity, similar to the United States Saturn 5 rocket. Former NASA National Space Agency officials said the United States was powerless to stop China's development in the space field, saying that the United States should regret not cooperating with China to make China progress so much.
The rocket engine tested this time is the YF90 220-ton rocket engine of the second stage of the Long March 9, which is a step further from the Long March 9, according to reports, the Long March 9 heavy carrier rocket is scheduled to be launched at the Wenchang Cosmodrome in Hainan in 2028. The Long March 9 currently adopts a three-stage semi-power configuration, and when ensuring the progress of the YF90 220-ton rocket engine, it will tackle the first stage of the rocket and the booster YF130 480-ton liquid oxygen kerosene engine, and the Long March 9 carries the hope of China's future deep space exploration and the establishment of bases on other planets. China's continuous breakthroughs in the field of aerospace have made American rationalists and objective people begin to reflect on whether the US blockade and sanctions against China really work, why China is more and more powerful the blockade, perhaps they have forgotten that China does not believe in evil, Chinese indomitable spirit, inspiring Chinese scientists to constantly break through, what European and American countries can do, China can also do, and even do better than them.

And the Long March 9 in this year and broke the earth-shattering news, which makes the European and American countries very complicated in the heart, according to media reports, China's carrier rocket and aerospace engineering technology experts, Academician of the Chinese Academy of Engineering Long Lehao revealed a new Long March 9 configuration scheme in a speech, compared to the four boost version, the new plan of 2021 is very challenging, is a subversive change, it is not too much to say that it is to tear it down and start over. The new scheme of 2021 is the light rod version of the Long March 9, the Long March 9 of 2021 has no booster, the whole rocket looks like a pole, the bottom of the first stage, evenly arranged 16 YF135 engines, the second stage and the first stage is a 120-ton hydrogen-oxygen engine. In terms of structural layout and layout, similar to Saturn 5, this means that the 2021 version of the Long March 9 will represent Asia, becoming one of the most advanced rockets in the world, and the corresponding technical difficulty will be higher.
In fact, the Long March 9 has 3 configurations, the first two have different details, but the overall is the traditional four-boost version, and the 2021 version of the Long March 9 is a single-pole version. European media lamented that China is catching up with the United States with its own strength, and even about to surpass Russia. Some people are very concerned about the 2021 version of the Long March 9 rocket, and some people wonder, since the 2021 version of the Long March 9 is better than the previous Version of the Long March 9, why not choose to use the new configuration of the Long March 9, in fact, it is not not used, but it has not been waited. China must land on the moon by 2030, and if it uses the 2021 version of Long March 9 at this time, it will have to wait until after 2032, or even 2035, to carry out the lunar landing mission. The time required for a rocket from the proposal to the completion of the test to the launch is quite long, as short as several years, and the long one takes more than ten years. Even the American Ares 5 heavy carrier rocket has not yet completed the test, let alone launched into the air.

Countries around the world attach great importance to deep space exploration, especially China proposed to establish a lunar base, after landing on Mars, some countries can not sit still, in addition to the United States and Russia, as well as European countries and Japan, even India is also clamoring to land on Mars. In this space expansion game, China's opponents are actually only the United States and Russia, especially the United States, the United States clamored to curb China's development in space, China naturally can not show weakness, must show to the Americans, China is what they can not stop. At the same time, China's expansion in space and the establishment of planetary bases are also seeking the well-being of all mankind, which is of great help to high-tech development and materials science and medicine, and the Long March 9 will be an important beginning.
