- Опубликовано: 4 июн 2024
- China is now the number one nation in terms of rocket launches, with most of its launchers tracing their design heritage back to the Dong Feng 5 ICBM.
This includes the Long March 2, 3 & 4 - all propelled by YF-20 family Engines burning UDMH & NTO
The Newer Long March 5,6 &7 all use new cryogenic propulsion systems.
Long March 11 is a solid rocket based system.

He misspoke at 3:21, when he says: “The Feng Bao made 8 orbital launch attempts over its career, with only 8 of them being successful”.
He meant to say 11 attempts with only 8 successful.
Was about to say... 8/8, not good enough. Kind of a tough customer.

Wikipedia says the Feng Bao 1 had 11 launches, and 4 failures. Definitely misspeaking somewhere in there.
Love the fact that you're doing these types of videos. Would be awesome if you could a similar video on Europa through Ariane 1-6, the indian SLV->ASLV->PSLV->GSLV Mk2/2+/3 or a "History of" type video like you did for Atlas and Delta. I mean who wouldn't want a 15-20min long video of the history of the Titan family.
Excellent suggestion.
Agreed!
Also the SSLV for India, which is slated to launch next year
*Yes that would be great*
There is one for Atlas, but I don't think any of the others.
3:21 It made 8 orbital launch attempts with only 8 of them being successful? That failure of a rocket only achiving 100% launch successfulness

Tiger moms, man it's never good enough for them.
@@yanDeriction Haha, that crack me up. You only got 8/8, we need 9/8!
@Martian Engineer Everyone's slacking compared to SpaceX :P
@Martian Engineer failure is the mother of success
The Chinese Space Program is a bit like if the US kept every version of the Atlas ever build in servies to this day
That's basically what the Soyuz is too. In the end it's just based on a very old ICBM.
but if they disregarded where the rockets or it's jettisoned parts will crash
@@totallynoteverything1. Exactly why they built that new launch site on near Hainan. Not every country have the luxury to have a wonderful place called Florida or Mojave desert. (Most developed area of China is alone east and most desert are not easily accessable due to their relatively high altitude)
And yet its still most cost effective and reliable. Unlike the US, only for flashy propaganda but totally impractical. Now looking back,the shuttle was such a joke. Overpriced. Impractical. High maintenance. Highly inefficient. Nothing more than just a PR coup.
@Fred H
Wrong. The shuttle was designed that way for a specific mission that the DOD wanted done. The shuttle was able to get all its funding because it designed it specifically to be able to do that mission. I suggest doing a little research.
As a chinese, what i know about our rockets is that they are all long march 长征, some are huge and tall, some are small and short

Absolutely wonderful and faithful video. One small detail: it would've been helpful to include "Long March" titles in-between rocket family transitions just in order to give some extra level of awareness to the viewer.
It's weird. When I first subbed to this channel it was shortly after a friend of mine introduced me to KSP and subsequently to Scott. I started watching the KSP vids that had to do with realistic physics concepts and real life astro things, that led me to watch the videos that are straight up just physics. Now the channel is mostly talking about rocket designs, reactors, motors, space news and whatnot and I still watch every video. Also I ended up discovering Frasier Cain through Scott (can't remember how). I'm not a physicist and certainly no astronomer (chemistry undergrad), but I love watching these. Scott explained how the Chernobyl reactor worked in a way that I understood and can actually relay to others.
Now I see why you needed to take a break from this and play Kerbal.
Personally, I need a break to play kerbal whenever I so much as think about China. I'm trying to get banned so that I can put it on my resume.
@@revenevan11 Guess you'll have to stick to KSP then, I'm afraid 😛, and leave real rockets to the Chinese.

Long March 5 just had its first completely successful launch yesterday (Dec 27, 2019), capable of delivering 25,000 kg to LEO and 14,000 kg to GTO

I was very impressed with the size of the cx 5 when it was launched, but now very excited to see the CZ 9 rocket when it is finished😱
Previously, every rocket needed to be modified to fulfill the requirements of each mission, so there were tons of types, the CZ-7 was originally called CZ-2/HF, "HF" means change engine, some of the CZ-5 designs was shifted to CZ-7 due to its core stage diameter. The bad naming issue could be ended up in these new series of rockets been developing. I'm happy to see that CASC started to use digits which refers to the stage number, booster number sth. like that to name the rockets' sub types.
Great video! I just want to add that the LM-5 Y3 just launched successfully yesterday with live coverage. Many more LM-5 coming up in 2020!
90% of the time, you literally post a video a day or so after I think about a certain topic that sparks my interest... And the video is about the topic I was thinking about. . . WTFalcon? I think we are vibing on the same wavelength Scott. Your f-ing amazing.
Thanks for answering my questions and explaining everything I think about, you telepathic beast. No wonder you do so well on RUclips!

Scott your as "perfect" as any human being I know! Absolutely amazing!
While it would suck at the time, having a rocket land on your house would make pretty cool story a few years down the road.
Yeah I could see myself telling that story over and over again at my oncology appointments. Because cancer probably.

And, now it's gone.
No as a westerner that has never learnt Chinese pronunciation you did very well getting those names as close as possible...
There's so little material about Chinese space program that is properly translated to English, thanks for making videos about this~
im sure youre sick of chinese space tech, but i would love to learn more about the Long March 11 launch system from the barge. looks friggin awesome
It's basically a df-31 missile, the rocket was designed to quickly and safely replenish lost satellites during wartime.
Very well explained, thanks!
Going to hit 1 million very soon. It's because of your talent, balance and hard work. Early congratulations!
Actually there are changes in recent years about how Chinese media publishing the results for the space program.
There's a documentary about the first limping launch of CZ5 that offers the reason for delaying a couple of times, also a few TV shows has invited the launch control team and the technician that called out the pause in the 10s countdown for interview/talks. but these are all in Chinese and broadcasted on Chinese platforms, some can be found on RUclips but not many.
Thanks for covering another huge gap in my knowledge, this one beeing about chinese rockets! Now I just have to learn about almost anything minus one. What exciting times lie ahead of me! Thank you for sharing your research, Scott.
Can you do a video about the briz-M stage for the proton, specifically the fuel crossfeed
Yes! Been expecting this one.
Man it is crazy how much stuff falls off those rockets when they launch.
tanks608 one of the assembly staff told me those debris are used for temperature keeping prior to liftoff
Insulation, it’s supposed to fall off
@@scottmanley omg the man himself, isnt insulation falling off and striking the vehicle what took down Columbia though?
@@tanks608 when it reentered yes because it put a hole in the heat shield. But this doesnt need to reenter
@@tanks608 a think a foam caused it not sure
The long march 11 launch looks similar to that of an SS-18 ICBM where the rocket is ejected out of its container and into the air before the rocket engine ignites
It is an ICBM derived rocket, derived from DF-31 ICBM, a spy leaked DF-31’s top secret data to some foreign country (I believe it's USA) , rendered those missiles obsolete, but DF-31AG is still in service--the only two things DF-31 and DF-31AG shared are the look and the name.
Yeah, they repainted the launch vehicles at former launches, which obviously is military vehicles , and lately they don’t even repaint again
It’s meant to be cheap, easy to handle and transport.
Scott, was that an oversight by ya goodself at 8:28 when you said 4.2 KG to LEO.? Hardly seems worth the launch vehicle.
nice!a review about PRC's rockets!
Taking the Xichang Satellite Launch Center as an example, its booster landing area is called "Guizhou First-stage Rocket Debris Falling Area", involving 19 counties and nearly 2 million inhabitants. The area of the landing area is about 4,000 square kilometers. Each launch requires about 100,000 people to enter the evacuation area for about 10 hours. It's painful, but it had been done for every launch. You can often find videos of locals using mobile phones to record the fall of a booster on Chinese social media. I know it's crazy but it seems to be an entertainment for them.
Welcome back mr space guy
12:04 What is the russian Yenisei rocket? i haven't heard of it before and i couldn't find any information on it
It's also called Irtysh and Soyuz-5, you can find information under these names. It's still in planning but it's supposed to replace the Zenit-2 and Proton in the 2020's and later have a super heavy version with similar capabilities as the Energia, which I think is the version depicted in the image in the video.
Is that a GunStar next to the Falcon in the background?
There's some channels who's video I like before watching. This is one of them.
7:29 you don't fool us Scott, We know you are perfect and thy scalp is divine!
Great piece :)
Wow Scott. Epic! I can understand the procrastination with the Kerbal SRB only moon landing now....😄
Hey, Scott! You keep switching between payload to LEO, GEO, and GTO in this video, which makes it hard to compare the rockets. Would it be unfair to measue all launch vehicles on LEO? (Maybe do a whole show on measuring payload performance?)
Yes it would, because depending on the design of the rocket, for example the type of engine on the upper stage, it can make a big difference to what payload it can take to different orbits.
For example, Falcon 9 has a larger payload to LEO, where Altas V 421 catches up in terms of payload at higher altitudes, eventually overtaking Falcon 9 capabilities at a high enough altitude (about 12 tonnes at 1400km altitude). This is because the H2/LOX upper state on the Atlas is much more efficient which makes a big difference at high altitude.
I agree with this view: 【the courage to innovate means the courage to fail.】 The failure of the rocket launch was reasonable and acceptable.
Marveled at the rapid development of elon musk's space x, young engineers working at CNSA have criticized on social networks: "Chinese news media have always promoted the high success rate of Chinese rocket launches. Leading CNSA executives to fear failure and become too conservative, Technology innovation is slow. "
be greatful that China has a world class space program, while in my country, space is just an after thought.
awesome video!
Great and informative video
Could you do a video on finances behind rocket programs? I always wondered who insures a rocket launch against failure? Who funds and how do they (NASA, JAXA or any other agency) ask for funds for certain missions? I know not everyone is interested in finances but it might make an interesting video!
An insurance company will insure a rocket. If nothing goes wrong, they will make a big profit. When something goes wrong, they will declare bankruptcy. The insurance buyer will then cover their own loss. Even if the insurer doesn't go bankrupt, they will likely write off the lost asset with depreciation. A brand new rocket is worth 500m. But, after sitting out in the open for a few days waiting for launch, the rocket is only worth 25m. The insurer collected 20% premium of 100m. After rocket failure, the insurer pays out 25m less administration fees and compulsory excess of 12.5m. All in all, the insurance buyer gets back about 10m, which is quite good considering it could have been a total loss of 500m + 100m = 600m. Financing is very interesting indeed, and most people will think it's rocket science.
They do have real-time streaming of the launches, just not on western platforms like yt
I totally understand why you had to get some Kerbal time in between this research. I wish you had a paid team to help your research cause your videos are awesome
thank you for your explanation
Yay ! The classic spaceship and theme sound are back, along with "hello I'm Scott Manley". This is my favorite intro of any RUclips channel. I also like the way rocket parts just fall to earth in China. Hopefully I can visit there someday to see it. We just don't get that here.
The smoke from those crashes is insanely toxic. Those people shouldn't be that close, it's shear stupidity. The Chinese gov't actually warns them well in advance and instructs them to evacuate and not to go near the crash site, but they ignore it because they have a death wish or something.

Thanks Scott!
3:23 ...it made eight orbital attempts and only eight of them successful...
A 100% success rate sounds pretty decent :)
12:03 Wow Long March 9 look like much smaller, than other heavies rockets, but beat them all with 140 tons lift power. Have very effective engine. Exclude Starship with 150 tons, but Starship is much bigger in size, than Long March 9, but have only extra 10 tons lift power
Very true. But Starship is also meant to be fully reusable. So technically, Starship is in the neighborhood of like 200-300 tons iirc to LEO, but they won't do that.
The best space news RUclips channel...bar-none
good job! thank you!
9:57 Indian Semi-Cryogenic engine (SCE-200) is also based on RD-120. Ukraine and India in 2005 signed a pact to develop SCE-200 together. This engine will power Gslvmk3, ULV series, RLV(Resuable Launch Vehicle) and HLV.

Why is there panels Falling off the rocket at launch
the rocket is breaking apart (read @tanks608 's comment and replies)
@@14Thenger no, it's just insulation falling off as it's supposed to. It's not worth keeping the added weight for the tiny improvement in efficiency it would provide (by decreasing the amount of propellant lost to boiling), but while waiting on the pad it allows them more time to fill and trouble shoot any issues.
Daniel Leca me too I think it was the ice because of the cold fuel inside
Because it's made in China, duh
If you're talking about the one launching at 12:27 from the barge, those are spacers that hold the rocket in the middle of the tube that it cold launches from. Large ICBMs and those that launch from mobile platforms often use the same technique (see the Russian SS-18 or US Peacekeeper) and you'll see them fly off when the missile clears the tube.

"I'm Scott Manley, fly safe" don't talk to me...talk to the guys who drop toxic ballistic objects on peoples' houses...
Well if they complain, you can just shoot them. Or put them in a concentration camp. Oh the life of a nasty dictator must be nice.
They wiped out an entire town when one failed. They sequestered all the foreigners in the launch facility until it was "safe". Safe meaning until they cleaned up the disaster enough to let them go. When the foreigners left all they saw was lines of military blocking the view of the destroyed town. Some pictures did get out, it was pretty bad.
Chinese launchers were developed from surface to surface missiles and are still used that way. They just happen to lob a satellite at the same time.
Well, in fact, the locals would be happy to be hit by a booster in their house. First, the government will organize them into a safe area during the launch. If their houses and property are damaged, they will receive considerable compensation, usually higher than their actual loss.
@@John-pk4jm Everybody in the flightpath in a potential debris landing place is "organised in a safe area"? Yeah sure. It's China. That can only affect a tiny number of people.... not. Even in remote areas.
I very much doubt that point. Even for simply practical reasons. You can not plan where these boosters and other bits hit with any precision. That's nonsense. It would be an insanely large area.
Possibly IF people survive their house being destroyed they get a compensation? Or maybe not. What can they do if not?
Scott Manley, n-not perfect?! How can this be?!

4C has a restartable upper stage. 4A and 4B don't. Also, the CZ-4 family in general can accommodate different fairing sizes, so the 4B and 4C can use the same fairing types.

@@jiaruiyan870 I would have say, 1000000000 nm instead
It is by design though, but it sure looks funny.
At 7m40s, it looks like there's some orange substance (hypergolic fuel?) being dumped out of the first stage shortly after liftoff, and earlier, a bit from one of the boosters... anyone know what's going on there?
quite interesting thing they seem to do with assembling the rocket on the pad
