The launched was held today at the Wenchang Satellite Launch Center, south China’s Hainan Province.

Long March-5 has expanded the diameter of liquid-fuel rockets to 5 meters from the previous 3.35 meters.

Its highly stable and cutting-edge control system is of great significance in China’s upgrading of its carrier rockets.

Started in 2006, the design and research results of Long March-5 have helped with the manufacture and successful launch of Long March-6 and Long March-7.

Long March-5 is the first to use the No. 1 launch pad at the Wenchang Satellite Launch Center, which is China’s first launch center along the coast line.

It is scheduled to carry the Chang’e-5 lunar probe into space around 2017.

Please delete previous message, I don't know how to quote, but I was replying to Blackstone

Its true China still needs 100ton + LEO rocket like Saturn V to match what US did in the 1960s

But few people know that, by today's standard, Saturn V is still state of the art technology for 2016, and when US give up on that rocket, they actually have lost the technology and know-how.

Because for a rocket as complex as Saturn V, you need millions of parts, and many of those parts were customize build by company and R&D that was created for them only. Once US govt decide they no longer need it, all of those company and special assemble knowledge literally became useless overnight.

Also I don't think they lost the blueprint for Saturn V, but there is only so much blueprint can do, a lot of assembly and constructions cannot be recorded on paper, they are passed down from man to man, word to word. And once it stops, all the secrets are lost.

With the success of LM5, I would say right now, China is on part with some of the world's best current heavy lift rockets.

US is still ahead, because they have started research on the SLS a decade years earlier than China, and they still some know-how and blueprints from Saturn V, but I don't think by so much judging by the difficulty and timeline of its development. Falcon Heavy on the other hand, if successful will be a huge difference, but it is 50ton LEO rocket is still half of SLS or Long March 9

From what I see it, 1960s Saturn V is irrelevant for today. So its not a race between 1960s USA vs 2010s China

Now its a race between 2030s SLS vs 2030s Long March 9, right now SLS's progress ahead, but never underestimate China.

In the end, this competition benefit both side as well as all mankind, everyone wins.

One of China’s top aerospace technology companies unveiled the first satellite smartphone designed for use with the country’s a first mobile communications satellite, Tiantong-1 (TT-1), at the six-day Airshow China in Zhuhai, Guangdong, which wraps up on Sunday.The new smartphone, developed by state-owned China Aerospace Science and Technology Corporation (CASC), is scheduled to go on sale in two to three months, where it will compete in a global market dominated by the British Inmarsat system.

CASC launched TT-1 into an equator-hugging, geostationary orbit about 35,000km above the earth on August 6.Satellite experts said the new satellite smartphone was a product of the “space-based Silk Road”, a long-term strategy proposed by Chinese aerospace companies, institutions and scholars to support the country’s “One Belt, One Road” initiative.

“The TT-1 smartphone is so far capable of covering the territory of China and the whole South China Sea,” an engineer from CASC’s Fifth Academy, based in Xian, Shaanxi province, said. “We are going to expand our coverage to the whole world by launching a network TT satellites in the next five years, because our ultimate goal is to replace Inmarsat, or even surpass it.”

Since no one mentioned. This launch is quite thrilling. Multiple "error" occurred during the launch and prepare process, launch time is delayed multiple times and there is even an "abort launch" command. Luckily those genius at launch center fixed the errors, made the judgement that the rocket is good to go and delivered a hell of a show to us.

Thursday saw China successfully launch its new Long March 5, but neither the launch nor its decade-long development was anywhere as smooth as would have been hoped - and there has been a refreshing openness about these issues after liftoff...
