What's Going On with China's Equivalent of SLS? 

That’s my understanding as well, let’s which ones really see the day 🙂

Like cars with different engines' capacities but kept the original shell, in fact, with cars, they are harder as their engines are inside, where else the rocket boosters are like hot rods, no such problem. 🇧🇷🇷🇺🇮🇳🇨🇳🇿🇦

I'd say the new requirements of reusability force these changes. They believe it is easier to achieve that by putting all the first-stage engines together as a whole than by taking them apart. The question now is, can 21st-century technology solve the problems of the old Soviet moon rockets?

@@DongfangHour Its actually different design iterations, and CASIC is experimenting almost all of them. Long March 9 is more like a project name and will be the name of the vehicle once vehicle is in production. For example, J-9 fighter had more than 5 different designs, technically they are all called J-9, but only the one that put into production will have the name of J-9. It is also possible to have almost entirely different design under one name, like J-8I is a fighter with nose intake, J-8II is a fighter with side intakes, the design is vastly different due to change of intake location, but both of them are called J-8. I will not be surprised if there are two variants of LM-9 in service, like LM-9I and LM-9II.

Haha, you have a point 😄

确实，我也是今天刚发现。有心了

Thanks Dave!

It’s probably cheaper

@@franksun4017 And add redundancy, with the mechazilla you only have one chance, the landing has to be perfect, but with this one you have several meters of margin.

@@Pakicetus_ true，blowing up rockets isnt fun.

Thanks for the kind words! The interview with Ellie was fun for sure. And I fully agree, the more space stuff the better... 🙂

You know those things.Thus your pro must be same as those crazy rocket lovers.

I think they are going for YF-135, which is the optimised version of YF-130

I agree with you. Since human lunar landing does not need long march 9 any more. YF-135 would be half of YF-130 just like Russia's RD-191 to RD-180. This would be the most fast/cost saving path.

Good points @Duya Taksis 🤔

you are right about 240t engine, I remember reading about it in news.

谢谢你让我知道了他在讲什么😂

🙏🏻

Thanks Jeff! Glad you enjoyed the interview with Ellie 🙂

Thanks Janice for your kind words Janice! I had no idea that some people were copying the program… I’m curious, which channels are you referring to?

@@DongfangHour when you have someone keeps on worrying about you, keeps on making up BS about you hope to slow you down and make waning number one position last just a tad bit longer - you know you are doing something right 🤭 I like all the colorful labels your presidents and NATO president come up with China, "systematic threat", "pacing challenge", "ex$itial threat" (some of them are too colorful to mention here), we only have to say that *we are honored 🤭*

@@DongfangHour You can be honored by something of your propaganda, something does not exsit, here is something for you to proud that does exsit, such as how iPhone got its idea of its camera module, how RU-vid got its idea, how ASML got its idea of immersive EUV (currently its most advanced), Biden's infrastructure project, DDGX ... these are things that actually happened and worthy of you to be proud of

Thanks Matt! That sounds like a good idea, I might wait a few months though because there isn’t much information available (yet)

CZ5DY is very different from the currerent CZ5. It will be the rocket for human lunar mission(2 separate launchs). It will have around 70ton leo, using 21 yf100k engines for first stage, simlair to falcon heavy.

I don’t know, there isn’t any further information beyond Long Lehao’s PowerPoint AFAIK…

We call it "technological reserve"

It is not like they need to milk government contract for as long as possible with outdated tech like you-know-who.

No research effort will be wasted. Competition makes progress, even better when you have the budget.

There’s no mention of stainless steel in any case 😉

Normally yes 😉 launch is now scheduled for November 29.

Thanks

Well, within 4 years, Long March 9 will launch its maiden flight. We shall wait and see. Doesn’t matter what people like you and me say, we have been proven wrong many times about progress of China ambitious space program so far.

“The development of China's liquid rocket engine has good news. Yesterday, the first complete test run of China's largest thrust liquid rocket engine(500 tons) independently developed by the Sixth Institute of Space Science and Technology Group, as well as the first complete thermal test run of China's largest thrust 80-ton liquid oxygen methane engine, were a complete success.”--posted news on 05th, Nov.2022.

A powerful rocket engine developed by China has passed a "milestone" test, according to a Nov. 6 report on the website of Hong Kong's South China Morning Post. China Aerospace Science and Technology Group (CAST) announced that the Sixth Institute of Aerospace Science and Technology (Sixth Institute) has successfully completed the first complete test run of China's largest thrust liquid rocket engine, saying the result is a milestone for China in building an aerospace power. The report said that on Nov. 5, the Sixth Academy of Aerospace completed the complete test run of the 500-ton liquid oxygen kerosene engine. The 500-ton liquid oxygen kerosene engine has about four times the thrust of the existing 120-ton liquid oxygen kerosene engine, according to the Sixth Aerospace Institute. The new engine's maximum thrust also exceeds that of Russia's RD-180 rocket engine - one of the world's most powerful liquid rocket engines currently in use. The development team of the Sixth Academy of Aeronautics and Astronautics said that after nearly 10 years of dedicated research and development, it has innovatively adopted a fully digital design and management model for the first time, breaking through a series of key and core technologies. The engine is expected to power the Long March 9 launch vehicle, the report said. China is developing the Long March 9 launch vehicle to send astronauts to the moon around 2030 and to set up a lunar research station around 2035 along with Russia and other potential international partners. Using this engine will give the Long March 9 a takeoff weight nearly six times that of the Long March 5. China used the Long March 5 on the Chang'e-5 launch mission in 2020 to successfully return samples from the lunar surface. In late October this year, China also used the Long March 5 to put the last module of the Chinese space station into orbit. A launch vehicle using this engine will also support China's space ambitions to explore Mars and other planets.

@@feihuo7874 500t, that should be YF130. CASC plans to develop 9 liquid rocket engines in 8 years(2012~2028).120t engine is not on the list.

@@ooxx201 How do you know about the progress of engine development of China?

Hahaha, and I thought no one would notice 😄

@@DongfangHour exposed

Absolutely, the footage of the LM9 mock-up towards the end of the video are from Zhuhai.

@@DongfangHour I was going to mention that as well because I've been following the Zhuhai airshow online and stumbled upon that CGTN video where a guy is holding up a toy model of the supposed LM9 with reusable core stage, he even took it apart as he was describing the rocket. Apparently you also saw the CGTN footage. I have virtually zero knowledge of these things but I agree with you and at the same time find it more plausible that their main goal will be about making successful launches and achieving the actual objectives out there on Mars or wherever in a timely manner...assuming a reusable LM9 will take considerably more time and therefore making it a secondary goal.

@@DongfangHour I am Chinese in Guangzhou not far away from Zhuhai

Or any rocket for that matter! 😂

Too early to tell

SLS = Space Launch System

Scrub Leak System.

Space is nowhere near the China moon shot. Wait unit Musk landed on the moon, then compared with China.

Like the space station？

Yeah, that circus called SLS is clearly off the Chinese sketchbook, lol

They try to do something interesting and innovate. Must be trying to steal from westerners. Cope some more.

Yeah right. I suppose you were attending China space program committee meeting recently. Thx for your inner circle updates.
