China Wants to REUSE Old 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

that wire capture animation is genius

Well done China🇨🇳👍👍👍

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 .

Awesome!

🙂Thank you for your updates🙂👍🙏

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.

Woah new logo! Looks dope

Love this channel ❤

Really appreciate the coverage and the work that must go into providing it ... Thank you!

LOL! Your new Dongfang Hour logo reminds me of China's High-Altitude Weather Balloon! (Except it's not a White Balloon)

Great channel… love your vids… respect to you!!! 👍👍👍

Great content! Many thanks

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.

@2:38, great research and display of info.

Thx 4 the News. Grüße aus Rostock-Germany! ;-)

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.

kinda missed the red since that's kinda our color and it's also kinda in the channel's name?

i'm impressed

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 RU-vid 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! -wendy

Great video

Thanks for the great video!

It's a cool idea to use parachutes, but I think reusable rockets are the way to go.

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.

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.

Thanks

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?

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.

Thx for sharing

probably they found out that things flying down with high speed from the sky might be an issue

Great channel…

Reusability can save money,time and resources.Reusable boosters that can decent vertically on a flat surface can make that happen.

I wonder if the CIA or FBI is monitoring him because of the wealth of information he brings us about china

It's super nonsensical but I'm so worried about the Mars rover. LOL

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!

wouldn't purpose built reusable rockets better than using old ones?

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

I still think 東方 text in the logo is giving more nuance.

First

It's amazing to see a young lady like this doing a podcast on rockets.

I like your t-shirts can you send me one

Copying Elon Musk China's good at copying!

very good content!!!!
