China's largest rocket is undergoing final assembly at a facility in Tianjin ahead of its shipping to a coastal launch site for what will be a crucial mission for the country's space ambitions.

Footage aired on China Central Television (CCTV) on October 6 showed components of the Long March 5 at the factory under the attention of engineers.

The two-stage, 5-metre-diameter, 57-metre-tall Long March 5 launch vehicle is by far the largest and most capable in terms of payload capacity that China has developed.

This third Long March 5 rocket is being readied to launch a near-8-metric-tonne experimental communications satellite named Shijian-20 to geostationary transfer orbit sometime in January 2019.

After a successful maiden flight in November 2016, the second failed to reach orbit in July 2017, severely disrupting China's space plans.

The failure delayed a number of major missions, including the Chang'e-5 lunar sample return mission which was scheduled for November 2017.

A variant named the Long March 5B had also been expected to have a test flight ahead of lofting the first 20-tonne module of the Chinese Space Station (CSS) into low Earth orbit.

January return to flight
The cause was determined to be damage to the turbopump on one of the two cryogenic YF-77 first stage engines, prompting a redesign of the structure and test-firing in Xi'an.

Success of the upcoming launch will be crucial to progress on China's lunar, space station and interplanetary exploration plans, with the Long March 5 also to launch an orbiter and rover to Mars in summer 2020.

After testing and assembly of the third Long March 5 in Tianjin, north China—expected to be completed later this month—two cargo ships designated Yuanwang 21 and 22 will travel from the Yangtze River to collect the components and transport them to the island of Hainan in the South China Sea.

Following this two-week process, a two-month long campaign to get the Long March 5 vertically assembled and integrate the Shijian-20 communications satellite with the rocket with take place at a vertical assembly and testing building at the Wenchang Satellite Launch Centre.

Launch could then take place sometime in January, which unlike China's three closed inland launch sites will draw thousands of spectators.

The one which failed to rich orbit and still declared successful? Even second one was declared successful untill US revealed that it has fallen into sea.
The satellite is in service until today. It is a satellite a generation ahead of Indian ones. Your MKiii can only launch 4 tonnes...that's a 25 year old Chinese capability. You do know that right?

Sijian 17 launcher is new LM5 and there was "underperformance" in second stage I think. They had to balance by firing higher stage rocket motor for longer than planned. This is totally new heavy launch system and of course some bugs are going to be around. US rockets also fail all the time and European ones too (this is where Indian and Chinese records are pretty decent and compares well with western ones). LM5 failure in first two was small scale. Second failure little worse than first one because the Satellite was still delivered to Geostationary orbit and currently operates. No one has disputed that or offered evidence to contradict this.

What is India's heaviest delivery to Geostationary at the moment? and to LEO? Not really on topic but I looked it up and the claim that India has heavy lifter depends on how a person defines heavy. The heaviest ISRO one is 4 ton to GTO and LM5 is 14 ton to GTO. China's previous generation of main utility rockets launch 5.5 ton to GTO.

No... It just a mediocre rocket payload that cant even match long march 2B. Heavy rocket means at least 16tons payload to GTO. :enjoy:

Dont try to give the delusion you are on par with China space power, you are far from it.

Even our long march 7 which has 2 successful launch and far bigger payload than anything india space can throw, is just a medium size rocket for CSA.

The first satellite reached orbit.
