What tasks did the "Long March" rocket, which contributed to the "six wars and six victories" of the lunar exploration project in 17 years, undertake →

In the 17 years of lunar exploration project "six wars and six victories", among them, the credit of the "Long March" series of carrier rockets is indispensable, in the lunar exploration project, which Long March rockets have been used, and what different tasks have they undertaken?

The rocket model in the China Academy of Launch Vehicle Technology is part of the Long March series of carrier rockets, and a total of 4 Long March series carrier rockets were used in the mission of the entire lunar exploration process.

Long March 3 A, commonly known as Chang Sanjia. It is known as the Gold Medal Rocket, and the more famous payloads it launches include the Dongfanghong-3 satellite, Beidou-1 and the first mission of the lunar exploration project, Chang'e-1.

Long March 3 B, commonly known as Long March 3 B, adds 4 boosts to the long three A, making its power more powerful. It has mainly launched the Chang'e-3 and Chang'e-4 probes.

Long March 3 C, that is, Long Three C, Long Three C also carried out two launch missions of the lunar exploration project, one is the launch mission of the Chang'e-2 probe, in addition, in 2014, the Long March 3 C also launched a type of re-entry and return tester, mainly to verify the re-entry and return technology, laying the foundation for the subsequent Chang'e-5 mission.

In addition to the chang'e 1 to 4 missions, the rocket used by Chang'e 5 is the most capable of carrying China's new generation of carrier rockets, that is, the Long March 5, commonly known as "Fat Five".

In December 2020, the Long March 5 Yaowu carrier rocket carrying Chang'e-5 was successfully launched in Wenchang, Hainan, which also opened the final step of the three-step lunar exploration project. The Long March 5 very precisely sent Chang'e 5 to its intended orbit.

How accurate is the launch? After the launch, Chang'e 5 entered the predetermined orbit very smoothly, and did not do too many orbit correction actions, which also laid the foundation for the next mission of Chang'e 5, because a lot of fuel was saved, so Chang'e 5 completed some expansion actions on the basis of the existing mission actions, such as the controlled moon collision of the orbiter and so on.

It can be said that during the entire lunar exploration project, the Long March series of rockets was launched 6 times and succeeded 6 times, "six battles and six victories", which made great contributions to the successful conclusion of the three-step lunar exploration project. In the next step, in order to meet the needs of more space missions, the Long March rocket is still in the process of designing and developing new models, such as the longer heavy rocket with greater thrust - the Long March 9 and the new generation of manned rockets developed to meet the needs of the next manned moon landing. It is believed that in the near future, we can see that the Long March family will continue to have new family members join in, making greater contributions to China's aerospace to a deeper and farther space.
