China Wants to REUSE Old Rockets
Вставка
- Опубліковано 8 лют 2025
- China is seeking to make its older generation Long March rockets (partially) reusable, while at the same time also developing new-generation reusable rockets. In this video, we explain the reasons the Chinese state-owned launch industry could be going for this approach, and the roadmap ahead.
The move remains puzzling nonetheless, especially with domestic commercial launch startups getting very close to launching for the first time VTVL reusable medium-lift rockets.

The effort that goes into these videos is insane data, timelines graphs, & other statistics. Most channels dedicated to China space industry don't even come close to dongfang hour
🙂+1🙂
Thanks so much for the kind words Edie! Glad you appreciate these graphs and animations, I do pour a lot of time into them 😅
They are very well informed and focus on the most relevant aspects.
@@DongfangHour Any updates on Chinese manned mission in thru space station ?
that wire capture animation is genius
Please keep up with the great work covering China's space programs and industry. Kind of makes sense in that they trying to make their old rockets reusable in terms it will do less damage and more controllability of the discarded stages .
Really appreciate the coverage and the work that must go into providing it ... Thank you!
Thanks @PinkLittleElephant, glad you appreciate the videos 🙂
Great channel… love your vids… respect to you!!! 👍👍👍
Nice new look with the updated professional rebranding.
Again excellent coverage, with easy to follow explanations. Wonder if part of exploring parachutes on boosters recovery attempts is to further develop parachute technologies. Could be useful for delivering payloads to Mars, for instance. Key to economical reuse, is minimizing any maintenance and facilitating quick turn-arounds between flights. It's fantastic to see so much diversity in the launch and space technologies China is exploring.
Love this channel ❤
Yeah can't disagree with you
🙏👍🙏
Great content! Many thanks
🙂Thank you for your updates🙂👍🙏
🙏🙏
@2:38, great research and display of info.
Woah new logo! Looks dope
Thanks!
It makes total sense. The technology will be proven, refined and universally adapted. For example, multiple strap on boosters could act as the first stage. By using lots of strap on boosters, the rest of the rocket could be designed around ignition when engines are already in a vacuum, when maximum Q is over, when aerodynamic considerations no longer drive the design, and with a 4,000 Km/hr head start. Also, every second of the rocket burn would provide acceleration in the orbital velocity direction, instead of burning fuel to get above the atmosphere (not contributing to orbital velocity). Reusable strap on boosters will greatly lower the cost per launch to get the rocket to 4000 Km/hr at a good altitude. A rocket starting at 4000 Km/hr and 100 Km altitude would at least double the payload into orbit. The reusable strap on boosters would certainly cost a fraction of the rest of he rocket. The reusable strap on boosters will progress rapidly down the learning curve … a stepping stone stage of reuse development with value in its own right, leading to core stage reuse from much higher velocities requiring retro rocket deceleration.
Awesome!
awesome content as usual thanks PEACE
Another well done video! Keep it up!
Btw can u guys maybe make some souvenir that has the old logo on it? I'm not saying the new one is not good or anything bad, just personally like the style of the old logo and that's why I want get some souvenir.
Hey Shawn, thanks for the kind words!
That's actually a cool idea, maybe having the old logo as a sticker or on a mug 🙂
Well done China🇨🇳👍👍👍
Thanks
Thanks for the support silversurfer! Much appreciated! 🙏
Good to catch up with you again, Jean. I had to attend to my own work at the end of 2022. The logo and the UA-cam site looks great. Also, you seem to have caught up with yourself too. I am writing a eMOVIE about News Anchors. The first of this trilogy's EVOLUTION -wendy BUILDING THE THIRD EYE. The movie revolves around an investigative news anchor who is being introduced and comes into contact with a world she finds difficult to accept by way of her concrete thinking and world view. I am writing it based on my own experience and on Tilda Swinton. Your transformation is an actual model for this characters story. Great job and good work Jean!

Thx 4 the News. Grüße aus Rostock-Germany! ;-)
Thanks for the great video!
Glad you liked it Cedric!
Great video
Thanks Daniel
My big question is not if China can succeed in developing very cost effective reusable strap on boosters; it’s a question of business and government direction … when a niche startup company succeeds, will they provide them to the whole launch industry and so launch companies will quickly leapfrog towards low cost per LEO payload pound, or will the other companies try to freeze them out and develop their in house reusable strap on booster. It might depend on how much the government wants to speed up launch progress in cost effectiveness and capacity and how much arm twisting to force the big players to equitably cooperate.
kinda missed the red since that's kinda our color and it's also kinda in the channel's name?
That's true, although I feel the yellow stands out a bit more, and I had been exploring it on thumbnails for quite some time now. Makes the channel look a little bit more coherent IMO 😉
Another issue with the red was that it made some people think the channel was government-affiliated...
@@DongfangHour eh with the political situation as is i am pretty sure as long as you are not clearly anti- you get labeled gov affiliated, shrugs. if you are you get labeled gov affiliated -- to the other gov
yellow black definitely stands out more sure, and yellow is the second main color for china... black is not though.
The sheer amount of methods being tested out by the SOEs is interesting, seems like bigger burden on the state's coffers, does that mean CNSA's budget is even more than NASA's?
You need to be aware that there is a considerable difference in the domestic purchasing power of the USD and the CNY in two different countries.
China has a lot of highly skilled well trained engineers , research Costs them a fraction of what it costs in the US
They can also manufacture the custom things they need for minimal cost due to their manufacturing dominance
It is simply about better work efficiency and conduct. Why waste resources carelessly?
i'm impressed
Great video as usual
Great work. China's space program is coming along nicely. When will china finish mapping the moon and choose a site and start preparing to build the lunar moon base? It will be unmanned to start but will be manned in the end right? Do we have a specified date for when it will be manned?
What is USA and Artemis timeline, and how realistic do you think these prediction or statement dates are? Iirc, china also recently updated their date forward to 2027 from 2030 or even 2035. I think that's when China will start building the moon base.
Thanks ex0duzz! One of the next videos will be on lunar missions, covering all your questions 😉
But otherwise until the end of the decade, we can expect 3 uncrewed missions (Chang'e 6, 7, and 8) and a crewed mission (involving hardware like the NGCS, the lander, and the Long March 10).
It's a cool idea to use parachutes, but I think reusable rockets are the way to go.
Thx for sharing
Great channel…
I wonder if the CIA or FBI is monitoring him because of the wealth of information he brings us about china
NSA as well?
@@wx365 thank you good person I had forgotten about those dirtbags as
As an American, I love your unbiased content. China's space program today reminds me of the US program during Apollo, and they did it themselves without any help or stolen Nazi German tech. Waited 50 years for this, the future is finally here.
probably they found out that things flying down with high speed from the sky might be an issue
hey dongfanghour its a fantastic job youve done im one of your fan will you decide to setup a new account on inland China‘s video app？like bilibili
TBH, I would like to some day. I would need to figure out a system to do the Chinese subtitles (and find the time...).
I know some channels on Bilibili are reposting my videos :)
@@DongfangHour hey dongfanghour good news Tianzhou 6 is about to launch think youre goingto be interected
It's super nonsensical but I'm so worried about the Mars rover. LOL
wouldn't purpose built reusable rockets better than using old ones?
Reusability can save money,time and resources.Reusable boosters that can decent vertically on a flat surface can make that happen.
As long as they work, do their job properly and save money go for it. Why waste it's smart
The only issue is, solid fuel rockets, infact all roctets, are very low cost in China!
There is little incentive for China to deploy reuse rocket technology!
I still think 東方 text in the logo is giving more nuance.

@@DongfangHour I like the old design better 😭
I like your t-shirts can you send me one
Hey Atomic Physics! It's available on our online store, as well as some other very cool space merch 😊 shop.dongfanghour.com/
@@DongfangHour seen them, seems they are very expensive for now, let me look for the $$ first
Can you send me one t-shirt, i know i cannot afford
It's amazing to see a young lady like this doing a podcast on rockets.
Copying Elon Musk
China's good at copying!
Du bist gut darin, ein LOSER zu sein😊
not as good as u copying the same words everywhere has sth to do with china Lmao
very good content!!!!
