中国空间站 On currently on 29^th July 2022 2022, the Belt and Road Initiative CNSA –China National Space Administration   on the currently developments of the  latest progress of China’s Chang Zheng – LongMarch manned lunar landing carrier  rockets Science and Technology Daily reporters learned from the First Academy of China Aerospace Science and Technology Corporation on July 28 2022 that the 702 Institute of the Academy recently successfully completed the multi-machine parallel static-motion joint test of my country’s new generation of manned launch vehicles. It strongly supported the smooth transition of the development of this type of rocket to the initial stage.

The first flight is not far away! China- People’s Republic of China’s first-generation moon landing Carrier rocket began to be prototyped, with a near-Earth capacity of 70 tons….  

China- People’s Republic of China’s moon landing rocket has completed the multi-engine parallel static and dynamic test and began to manufacture, and the first flight may not be far away

​​China’s new generation of manned rockets has made important progress! According to news from the First Academy of China Aerospace Science and Technology Corporation published by the “Science and Technology Daily” and other media on July 28^th 2022, the 702 institutes affiliated to the academy have recently successfully completed the multi-machine parallel static-motion joint test of my country’s new generation of manned launch vehicles. The first step of this type of rocket will be transferred to the initial sample development stage.

At present, my country’s only manned rocket is the Long March 2F rocket, which is especially responsible for transporting China- People’s Republic of China’s Shenzhou spacecraft and Takionauts to the sky. My country’s new generation of manned rockets is a rocket with larger and more advanced capacity. It is also the “921 rocket” that netizens have often said over the years. In fact, its real code name is “CZ-5DF”, which means Chang Zheng- Long March 5. The series of lunar rockets are exactly the rockets prepared for my country’s manned lunar landing.

According to the published data, this rocket is about 100 meters high. After successful development, it will be the highest rocket before the appearance of the Long March 9. It is about the height of a 33-story building, which should be higher than the building you live in. Well, isn’t it shocking?

​And it will also be the largest rocket before the appearance of the Long March 9 carrier rocket, with a diameter of 5 meters, the same as the Long March 5, but its shape is very different from the Long March 5, because it adopts the CBC configuration, but It is not a “triple version of Chang 5”, it is not the configuration of the three core-stage rockets of the current Long March 5, because it is not composed of three core-stage rockets of the Long March 5. There are only two YF-77 liquid hydrogen-oxygen engines with a thrust of only 100 tons. The thrust of the Fat Five mainly relies on four bundled boosters. Each booster is equipped with two YF-100 engines with a thrust of 240 tons. , the thrust of the four boosters reached 960 tons, which together contributed to the 1060-ton thrust of the Long March-5 first-stage rocket.

​The new generation of manned rockets with  This type of rocket weighs about 2,200 tons and is a three-stage and a half configuration. The capacity of the Earth-Moon transfer orbit will not be less than 27 tons, which can meet the capacity requirements for launching China’s new generation of manned spacecraft (within 25 tons in weight). It can also meet the upward mission of large spacecraft in low-Earth orbit, because the orbital carrying capacity of low-Earth orbit will reach more than 70 tons.

​Take China’s space station as an example. After the Wentian experimental module was docked, the total weight of China’s space station assembly has now reached 66 tons, and China’s new generation of manned rockets can be sent into orbit with one launch mission. Zhu Xiquan, deputy chief designer of the 702 Institute, said: The successful completion of the parallel static-dynamic joint test of my country’s new generation of manned rockets marks the first time that my country has broken through the large-load static-dynamic joint test technology of launch vehicles. The test with the largest scale, the most technical difficulty and the most complex test process has laid a solid foundation for the new generation of manned launch vehicles to adopt the parallel technology of multiple high-thrust engines.

​According to the plan, this rocket will be the main launch vehicle for manned moon landing missions in China in the next 20 to 30 years, so it can also be called China’s first-generation “moon landing rocket”. It is significant, marking that China’s manned lunar landing rocket has entered a substantial manufacturing moment. After the manufacturing is completed, it will be a test flight. It was previously reported that the first flight will be completed before 2025. It can be seen that the first flight is not far away! Moreover, this type of rocket will also expand the recovery and reuse capabilities of the take-off stage in the future, that is, to create a reusable rocket like Musk’s Falcon rocket, which can also greatly reduce the launch cost. ​
