Thanks kumbackquatsta! It was fantastic to have Brilliant reach out, they're a great platform and their product does match well with the topic of the channel :)
Can we just appreciate the Space players in their own right without having to compare or pit them against each other. Every Space player is a blessing to mankind in their own right.
So much precision math and physics are involved. I always wonder, how do you navigate in space? How do you know your position in this 4-dimensional existence? Maybe this is a topic for a video?
can I remake this video in kerbal space program and post it? basically i want to take your script but make it a live version in ksp with maybe some shots taken from your video as i find approriate
Very interesting explanation at loc 8:23 of how reentry angle depends on relative position of center of mass and center of pressure (area). See also an excellent demonstration of aerodynamic stability using weighted paper airplanes in ruclips.net/video/HESOat2iPzU/видео.html starting at loc 27:30.
That's a fantastic presentation you linked there, Jonathan, lots of great rocket science concepts packed into one hour. Even though it's meant for kids, I found myself hooked and watched the whole thing 😂
Hey Matteo, Melvin, thanks for asking. Both those programs are on standby for now. We're trying to figure out how we can keep them running in the future as they are side projects alongside busy full-time jobs. There's a good chance we keep the newsletter going. Not so much for the podcast... 🙁 Stay tuned!
With the grwatwst respect for your twchnical knowledge, the spacecraft's origins are back in 1962-63, when Korolov's team was developing Soyuz. You don't despute that, but China received a tremendous amount of technical support from Russia to develop Shenzhou. Now, there's lots of modern innovations on Shenzhou, the Orbital Module being at the top of the list. But Shenzhou remains in concept, a Russian design. And how's your Starship coming along? An original design, is it?
Yes, the Chinese chose to go for a proven design (Soyuz), and had some assistance from Russia for certain parts of Shenzhou. The newer NGCS spacecraft (currently in development), in contrast, is developed with indigenous means.
If I remember well, Russia helped with the development and is not lost on me that Tiangong 1 and 2 kind had the same goal for the TSS as the Salyuts had for Mir.
It's very hard to get a final opinion on this topic. I would tend to agree with the well-established book "China in Space" by Brian Harvey: "In 1995, the Chinese were looking to buy critical elements for their manned space program. They bought an entire spacecraft life support system, a Sokol spacesuit, a docking module, a Kurs rendezvous system, and a full Soyuz capsule though the latter was stripped down shell without any equipment or electronics." (p. 367). So yes the Chinese did get quite a few systems from Russia which served as precious building blocks. I believe there's still a lot of indigenous systems in Shenzhou though. There are also intrinsic design differences (orbital module notably), and you can see incremental improvements between each version of Shenzhou since 1999.
Why china cannot develope its own technologies and design, The shenzhou module is a licensed version of The Russian Soyuz crew module. I mean it's okay to take inspiration from other's work because starting every small thing from scratch is painful, but China is a whole different story they attacks NASA's & ISRO's servers to get information, copies a ton of other's technology and hardly develops technology by themselves. No hard feelings, but it's high time for China to develop technologies in house, stop doing cyber attack and give credit to the sources from which it's taking help in developing something.

Excellent presentation to laypeople appreciation. Complex space science in simple words. Keep up the great work Dongfang Hour 👍🇨🇳
Great explanation to the Chinese spacecraft reentry and landing process, thanks!!!
Glad you enjoyed it! 😉
congrats on the sponsorship. watching the channel grow and the quality remaining so high, you deserve the recognition.
Thanks kumbackquatsta! It was fantastic to have Brilliant reach out, they're a great platform and their product does match well with the topic of the channel :)
You guys are more professional and knowledgeable about space than NASA officials.
agree

This channel deserved more views!
The re-entry was very successful and fast.
another superb explanation that enriches my knowledge of space exploration as well as the Chinese efforts.
Glad you liked it!
very well researched, you even knew better than a native. You deserve more views!
Beautifully executed...kudos
So much precision math and physics are involved.
I always wonder, how do you navigate in space? How do you know your position in this 4-dimensional existence? Maybe this is a topic for a video?
Could be an idea 🙂 There are many ways to obtain one’s position and attitude: star trackers, inertial instrumentation, satnav (when in LEO), …
Professional! Thank you very much
Excellent explanation!
Thank you 🙏🏻
Love your content! Keept it up! 加油！
Awesome content!!
Thanks!
Well researched
Incredible channel keep it up
Great video!
Great explanation 👍🀄️❗️🙏
like the introductory video vignette and the soundtrack reminds me of RedDwarf TV series intro.
Another Excellent Video 👍
Nice one 👍 from Botswana
Magnificent !
So clear and consice
Thanks for helping my understanding of the magic involved in all that _______.
Just read some interesting comments. Thanks.

Hi Xiao, feel free to sample some of the video, as long as credit is given 😉
@@DongfangHour thanks

不错的视频 cheers
Congratulations to our motherland!
Thanks for the education 👌
My pleasure!
Excellent.
amazing
Have you guys stopped your newsletters? I haven't really been receiving it in my email recently
same for their podcast in audio format

@@DongfangHour yep, I figured it's plenty of extra effort. Even if we'll miss the podcast, we'll be here to share love with your videos and work!
outstanding episode👌👍
So pharking cool
What is the orbital module?
After separation, you said it has no further purpose. So it gets discarded? Burn up in the atmosphere?
What happens to the propulsion module? Does it get burned up in the atmosphere? or return to the Space Station?
Both the orbital and propulsion modules eventually reenter the atmosphere and burn up.
@@DongfangHour Thanks.
Good
别客气☺️
The chinese comand module use hidrazine or hidrogen peroxide?

So?
did you guys hear about the 1km hop test
Yep! Coming up in the next episode 😉
Thumbs up
i will never complain about the length of intercontinental plane flights again. taikonauts are tough and patient
It looks similar to soyuz even the rocket heads are same
Looks a lot like the soyuz, the shape, modules, the exact way its steered into the atmosphere with its shape... Is that on purpose?
Yes, the Chinese chose to go for a proven design (Soyuz), and had some assistance from Russia for certain parts of Shenzhou.
The newer NGCS spacecraft (currently in development), in contrast, is developed with indigenous means.
@@DongfangHour thanks. Soyuz is great. I wish the best to China.
😁 thanks.

Essex should tiyf P
Its very similar to soyuz, do you think Chinese shnzhou and Dragon capsule copied the Russian Soyuz?
If I remember well, Russia helped with the development and is not lost on me that Tiangong 1 and 2 kind had the same goal for the TSS as the Salyuts had for Mir.

Pointless to re-inventthe wheel
That’s god that has nothing to do with rocket science.

China is challenging the No.1 position of India in aerospace industry in Asia
我们只是做自己事情，我们不想和别人论长短。
Why does being the first matter???? I can’t wrap my head around it man.
Very informative but it is Russian technology that is Russian Shenzhou Spacecraft.
