China's most powerful carrier rocket, the Long March-5, is crucial to the launch of the Chang'e 6 mission. Here is how this Hercules of a rocket is assembled.

Before the Long March 5 Y-8 carrier rocket became this tall and sturdy sight that so many have flocked to see. It was first in pieces, in containers, shipped from northern China all the way to Qinglan port, in tropical Wenchang, Hainan province. Its pieces in compartments were still horizontal when on the road. Then, it's the assembly process unlike any other Long March rockets.

LUO XINSHENG, China Aerospace Science and Technology Corporation "We have an assembly process in vertical, where the rocket is hoisted to erect from a horizontal state. First step, hoist up Booster One, let it sit on the launch platform, and connect with the platform.

The first step assembly is special to Long March 5. Other Long March family rockets typically start with Core Stage One. For Long March 5, hoisting Core Stage One is the next step. It will hang on Booster One. Next are the three boosters. Each will connect with Core Stage One. Booster Three will first be put in place opposite Booster One, and then it's Booster Two and Four. In this way, the base is formed.

Next, Core Stage Two is put up. Meanwhile, in another workshop, the Chang'e 6 probe is added to the payload bracket in the fairing. This combination with the probe inside will be transported to our vertical assembly workshop and connected with the rocket. This is the last step of assembly."

The Long March 5 rocket is China's "most powerful" and fastest rocket to date. The rocket will start the journey for Chang'e 6, a historic mission to the moon. SY, CGTN, Wenchang, Hainan Province.
