I watched the launch live from Intelsat HQ in DC, as a member of Intelsat's ground network launch team. Usually we watched launches in the middle of the night from Kourou. This was a rare afternoon launch from China. We watched the launch on a large screen monitor, in my case we watched from the 3G pod. As soon as the rocket tilted two seconds into the launch, the video changed to static. We were told the Chinese government cut the feed. We had coworkers at the launch site and our immediate concern was for their safety. It was a few days until we knew our coworkers were safe. Soon after we learned about all the people who died as a result of a space rocket going horizontal and killing people along the way. Crying about it again. Fuck.

Another great presentation with excellent research and coverage. I'd argue the Intelsat 708 Accident was used, and not the cause of the political ramifications. While the Wolf Amendment was briefly mention, what's most significant is in April 2011, US Congress "banned NASA from engaging in bilateral agreements and coordination with China." This was part of a Department of Defense and Continuing Appropriations Act, not in legislation related to NASA specifically. This greys NASA's original mission of being having a purely civilian role in space activities, as this ban was implemented in military defence legislation outside of that specific to NASA civilian authorizations. Makes Bill Nelson comments included in the video appear as hypocrisy. The Wolf Amendment is a ban specifically directed at NASA, it does not specifically ban any commercial space activities. How things evolve, could get interesting as India is growing launch provider and a number of commercial launch providers globally will be orbital capable within the next few years. China is not the first country US has restricted technologies on rocket boosters. After World War II, Japan was banned from using inertial navigation systems on its boosters over concerns it might develop military missiles. As a result Japan's boosters to this day launch on a ballistic trajectory. Only the upper stage has guidance navigation. (a not so well know impressive accomplishment) On a positive note, in 2019 NASA collaborated with China for the Chang'e 4 mission on the Moon's far side by providing images from a lunar orbiter. NASA requested and received special authorization from Congress. The UN could work to clarify what member countries can and can not limit under the UN Outer Space Treaty, which is in much need of an update from its 1967 heritage. Perhaps we need another UN sponsored "International Geophysical Year" (1957-58), which was international scientific project to encourage scientific interchange between East and West after the Cold War of the previous decade. This planted seeds for many planet wide and space related scientific endeavours that catalyzed focus on technologies for use in space during the 1960's. Hopefully the geopolitical politics on Earth do not mirror into orbit and other worlds in our solar system. Not only in space, but humans need to better cooperate to address the climate issues on our home world.
Well said! I agree with you, the Intelsat 708 accident was not the cause but just one of the triggers that led to the subsequent restrictions. Back in the late 1980s and early 1990s when the US signed approvals to have American-made satellites launch on Chinese rockets, there was already plenty of criticism from Congress (including a certain Bill Nelson).
@@DongfangHour A Tl; DR from @AerialWaviator would be appreciated, but IMHO the Intelsat 708 disaster was used as an excuse for many policy decisions and probably a few new laws.
I remember this event, I was maybe 14-16 years old living in Budapest , Hungary at the time. I was very disappointed for the failure, and how everyone talked down on Chinese space program. American also ban China using the International space station. as teenage, I always feel that we are not able to catch in my life time with the west. fast forward to today, China has her own space station, Global position system, advanced high speed train. Chinese pulled it off well. I hope there are more to come for China in the decades to come.
I hope china stops censoring its citizens and corrects the human rights violations it commits. If they do that they will become a much stronger nation.
@@DongfangHour Too bad about your otherwise very good voice work. Please assume a more natural tone instead of dragging out every other word for effect. It sucks and is painful to listen to. Is this a genZ thing or just your take on the latest youtube fad?
I bit harsh from the USA. Military paranoia probably isn’t the most diplomatic response. NASA politician Bill Nelson gave a fine example of hypocrisy. I’d love to hear the farmers perspective though!
As China and the US get closer and closer to permanently manned moon outposts or moon orbiting manned space stations there should be agreements to avoid confrontations, conflicts , and misunderstandings and also to facilitate backup emergency rescues. That would be the prudent and wise thing to do but of course when you see each other as adversaries it will make this much harder. I enjoyed this video. Thank you for creating it.

The 3 taikonauts are just the latest of a series of unblemished record of crews to the Chinese space station, replacing the five months of the previous crew that welcomed them and six of them stayed at the station shortly before they bade farewell to the returning crew. China has a perfect record of space launches to moon, Mars and human to orbit payloads. Considering the fact that less than half of Mars expedition are successful, although China only has one attempt which is successful in launching an orbital vehicle, landing craft and rover to Mars all at same time. Also a clean record of moon explorations when compared to other countries attempt.
As a shout out to my Chinese friends, the Long March rocket program has recovered since the 708 failure, and is now one of the most reliable ways to deliver spacecraft into orbit and beyond.
@@curtisblake261 Yes, if you completely ignore the tendency for the Long March 6A to explode in orbit, which is currently the #1 contributor to Kessler Syndrome and the greatest threat to the continued viability of spaceflight.

Hi, I come from bilibili. Your videos are truly impressive. So... There's a guy translating your video into Chinese and uploading it there. I understand that you've given him permission, and he's doing it non-profit, which I'm grateful for. It's just... I can't help but wonder... why not just create your own account there? I'm sure people from China really love your content. And tbh, bilibili also lacks content creators (like you) who mainly focus on in-depth Chinese space exploration. You could just straight up hire that guy, or set up a revenue-sharing arrangement with him. Just a small suggestion though, and feel free to disregard it.

Hey Grayson, thanks for your kind suggestion and interest in Dongfang Hour! I have thought about opening a channel on Bilibili before. The main obstacle is the lack of time due to Dongfang Hour being a hobby (next to a full-time job). I'm currently trying to focus my efforts on improving monetization. With more revenue, I would be able hire a small team to help with script-writing/editing/translating/promoting + perhaps plan some exciting trips (filming a trip & guide to Wenchang for example). At the moment, Dongfang Hour is mainly 1-person operation (me) + a part-time motion graphics designer. Hopefully things can evolve in 2024, and perhaps a collaboration with a Bilibili creator can be envisaged 😉 Cheers Jean
Interesting comment. Spacecraft operators are careful about choosing outside insurance versus self-insurance. Which of course depends on the probability of a failure. Novelty is also a factor. If it hasn't been done before the risk is immeasurable. Also, risk of launch failure is completely different from risk of payload failure. How well tested is the payload, not just on its own but also through thermal vac and other stresses?
Parts of the TDRS satellite on the Challenger shuttle washed up on a Florida beach, including a TWTA waveguide filter. It was returned to HAC, was tested & still worked. -China got some good tech out of the crash.
4:47 “the accident was caused by a defect in the bonding of the inertial system” - This doesn’t tell me much about the root cause. Is this all the information that the Chinese released on the cause of the crash? Trying to connect the dots I am envisioning the navigation accelerometers or other devices used to guide or orient the rocket were bonded on to the substructure and became loose or fell off due to launch vibrations. Secrecy can be an impediment when you are trying to project confidence and trust to the rest of the world. Also from an engineering standpoint adhesives are quick and cheap attachment devices but are a horrible substitute for mechanical fasteners in a critical joint.
There is a more detailed description on the Wikipedia page of the accident in Chinese, but the English page is brief. I'm not an expert but I can try giving a rough translation here: An electric circuit fault caused the inner ring of the gyroscope to malfunction, giving out false pitch and yaw data to the onboard control system, which tried to correct the non-existent pitch and yaw error, causing the crash.
bonding here means connector failure rather than adhesives. Specifcally the eletrical connection for one of the four feedback loop is broken (offical phrase is no current flow) cause the navigation control is sense an non-existant deflection which the control tries to correct, thus cause the failture. below is the from the offical faiilure new report report in Chinese. 在分析、判别的基础上，通过大量地面试验，包括控制系统半实物仿真及大回路闭环试验，使故障现象得以复现。即由于四轴平台的随动环稳定回路功率级无电流输出，导致内环工作异常，致使惯性基准发生变化，同时向箭上控制系统输出了火箭在作正俯仰和正偏航运动的错误信息；控制系统为纠正火箭实际上并不存在的正俯仰和正偏航运动，控制火箭进行负俯仰和负偏航，箭体快速向预定射向右前方倾倒，最终撞到了距离发射场约1．85公里的山坡上，发生爆炸，星箭全部损失。
Thanks Scott! I agree, hopefully we can see more cooperation at least in the area of space exploration and space sciences. My gut tells me this is not for the near future though, considering the current hostility in Congress towards China.
They did, but the self-destruct system could only be activated after 15 seconds. The control center had a 7 second window to activate it (between T+15 and T+22s) but for some reason, they did not 🧐
"the first rocket launch without tested" - that's what I heard from the news at that time. OMG. "Without tested" . But China really learned from it. Chinese rocket launch had no failure for the next 15-25 years - best record, at least at that time.
Yes, in retrospect it was a big mistake. At the time, it wasn’t tested because the rocket was composed of parts from other rockets already in service. As well as budgetary constraints
I've noticed a growing trend of speech impediments wherein (younger people, usually) don't finish the last consonant of (seemingly random) words? Is this learned behavior, or something else? Genuinely curious...as it exists with some relatives of mine, too.
Competition and adversary is better for the advancement of space. A Chinese space power that is not in cooperation with the west would finally provide the impetous and funds to move forward.
Great reporting. Know your focus is on China. But an interesting video would be on the Sea Launch Program. The program bought the USA, Russia, Ukraine and Scandinavia together with major seed funding (6 launches) coming from an international London based organization. Sea Launch was based in Los Angeles. As part of that program an erection test was performed before the ships departed to the launch site near Christmas Island on the equator. Basically a USSR rocket being erected on top of oil rig platform in Long Beach. Imagine that collaboration today - how times have changed? This Intelsat failure was however the start of great power politics as some in the US could see the emerging threat to their global domination that China would become. The establishment and expansion of BRICS provides a key area of space related growth and collaboration efforts for the now mature Chinese space industry. it is also a logical extension/fit with the Belt Road Program to include international and domestic communication and other satellite based infrastructure systems. China will play a key role in providing these services to global south along with Russia and India. Cutting out the traditional domination by the USA and Europe.
Thanks Peter! Absolutely, Sea Launch would be a great story to tell, although it would require a bit more research effort on my part as it’s outside of my usual area of expertise. As you said, it’s crazy to think how times have changed
@@DongfangHour Unfortunately there was a golden moment of opportunity for global cooperation that the USA could have developed further but did not. Hopefully China can now lead the way with their Belt and Road, BRICS and space programs. Your reporting on the China space program is much appreciated. I worked with BAe, Aussat, Imarsat and then ICO. So was fortunate to have worked closely with USA, European, Russian, Chinese and the Sea Launch on many Comsat and launch systems. Including unfortunately a few launch and satellite failure reviews during the period of your last report. It's been a pleasure to see China's rapid space development from the early days. Please keep up your great reporting of it. The long term future of space lies with China now not with the West. Collaboration would be great but it's simply impossible in the current political environment that eminated in your last report. In hindsight it was a pivotal period more so than many appreciated including myself.
Yup, a very handy excuse to prevent the competition... As the result of this shortsighted foolishness, there is the Tiangong space station today, and the whole new space race where I bet on China rather than the US to establish a permanent Lunar presence first.
I heard that China was going to build in Africa Space Station that would be very cool and the reason is supposedly the best launch site in the world could be found there
This is a good report. I remember the period & repercussions well. Two things: 1. Nitpick: Don’t describe official US policy as a ‘blockade’: as you pointed out, for example, the Wolf amendment itself applies only to NASA/China bilateral (not even multilateral) activities (and also OSTP, by the way). “Blockade” implies a US iron ring around China preventing others from coming/going on space matters; & that’s not true. It’s about US components et al not being allowed to be part of any systems launched on Chinese rockets (etc.). That’s simply the US refusing to participate in bilateral space trade vis a vis China; hardly a ‘blockade’, ok? (Words matter; tho, I wouldn’t be surprised if that’s the word the CCP uses). 2. Going forward: Some of the countries that have signed on to participate with China in space have also signed the Artemis Accords- a voluntary, international code of behavior, consistent with the Outer Space Treaty, that, among other things, requires transparency in things like lunar activities. (It was that requirement in the AA for transparency that led several years ago for Russia to pull out of the tentative agreement to join the Artemis program). Now, the PRC is not known for its commitment to transparency. Yet, several of its now space partner countries have signed the AAs, which require it. It will be interesting to see if those countries do indeed cave in to normal PRC behavior for less-than-fully transparent operations - as you can tell, I’m afraid I consider that likely- or rather maintain their signed commitment to the AAs and transparency when it comes to lunar exploration and development. (It should be kept in mind: tho they have similar names, there is NO legal connection between the Artemis Accords codes-of-behavior, and NASA’s Artemis Program. India & Saudi Arabia have both signed the AAs; they are not part of the Artemis Program). - Dave Huntsman
Addressing your two points: 1. You didn't even watch the video before you replied, did you? 10:04 in the video literally told you the "blockade" nature of the US policy against China. Did you not see it or did you just ignore it? 2. Your Western brainwashed bias against China is so blatant it's hilarious to watch. To criticize China's transparency record while every country in the world has state level secrets is simple double standard. The US alone has three levels of security clearance throughout it's entire government: confidential, secret, and top secret. You just say China lacks transparency because when China doesn't tell you everything you want to know, it's China lacking transparency. When US or other countries don't tell you their state secrets, it's national security. Double standard at it's finest 😂
USA’s signature on any agreement is not worth the paper it’s written on. Native Americans learnt that long ago. The Vietnamese learnt that in 1972. Russia learnt that in the Kiev Accord. Transparency in U.S. government ? Go as Julian Assange, Edward Snowden, Chelsea Manning, Robert Hayes, Daniel Ellsberg, etc.
I suspect both ways. U.S. and China. China definitely did gain valuable technology at crash site. US most likely did sabotage the launch but to what extent? No one knows
With the current progress of the two projects, I think it is easier for China's plan to become a reality, especially since Shenzhou 17 is the 30th successful mission.

I've noticed a growing trend of speech impediments wherein (younger people, usually) don't finish the last consonant of (seemingly random) words? Is this learned behavior, or something else? Genuinely curious...as it exists with some relatives of mine, too.
Competition and adversary is better for the advancement of space. A Chinese space power that is not in cooperation with the west would finally provide the impetous and funds to move forward.
Thanks 😢
With all due respect, the conclusion you present is the epitome of naiveté.
Luckily, it's just some money + hardware they were lost as opposed to much more valuable human lives.
I mean that’s not true. The death toll was likely much much higher than the Chinese government’s lies
Great reporting.
Know your focus is on China. But an interesting video would be on the Sea Launch Program. The program bought the USA, Russia, Ukraine and Scandinavia together with major seed funding (6 launches) coming from an international London based organization. Sea Launch was based in Los Angeles. As part of that program an erection test was performed before the ships departed to the launch site near Christmas Island on the equator. Basically a USSR rocket being erected on top of oil rig platform in Long Beach. Imagine that collaboration today - how times have changed?
This Intelsat failure was however the start of great power politics as some in the US could see the emerging threat to their global domination that China would become. The establishment and expansion of BRICS provides a key area of space related growth and collaboration efforts for the now mature Chinese space industry. it is also a logical extension/fit with the Belt Road Program to include international and domestic communication and other satellite based infrastructure systems. China will play a key role in providing these services to global south along with Russia and India. Cutting out the traditional domination by the USA and Europe.
Thanks Peter! Absolutely, Sea Launch would be a great story to tell, although it would require a bit more research effort on my part as it’s outside of my usual area of expertise. As you said, it’s crazy to think how times have changed
@@DongfangHour Unfortunately there was a golden moment of opportunity for global cooperation that the USA could have developed further but did not. Hopefully China can now lead the way with their Belt and Road, BRICS and space programs. Your reporting on the China space program is much appreciated.
I worked with BAe, Aussat, Imarsat and then ICO. So was fortunate to have worked closely with USA, European, Russian, Chinese and the Sea Launch on many Comsat and launch systems. Including unfortunately a few launch and satellite failure reviews during the period of your last report.
It's been a pleasure to see China's rapid space development from the early days. Please keep up your great reporting of it. The long term future of space lies with China now not with the West. Collaboration would be great but it's simply impossible in the current political environment that eminated in your last report. In hindsight it was a pivotal period more so than many appreciated including myself.
Yup, a very handy excuse to prevent the competition... As the result of this shortsighted foolishness, there is the Tiangong space station today, and the whole new space race where I bet on China rather than the US to establish a permanent Lunar presence first.
9:09 and we are doing the same thing again in semiconductor industry to China.
It’s not about all the people that died but instead all the things we learned along the way
Why can’t you say congressman. He is a congressMAN.
@@alandashcar1453 not crying, just pointing out woke bullshit when I see it.
@@alandashcar1453 you are just a stupid troll. That’s all your replies are is just stupid troll posts.
I heard that China was going to build in Africa Space Station that would be very cool and the reason is supposedly the best launch site in the world could be found there
at least China learned to make good rockets now.
Dropped a like😆
You don't know this before?
It was a success, they collected lots of invaluable data
Iuck
3am💀💀💀
Failure is good... Success will come later.

This is a good report. I remember the period & repercussions well. Two things: 1. Nitpick: Don’t describe official US policy as a ‘blockade’: as you pointed out, for example, the Wolf amendment itself applies only to NASA/China bilateral (not even multilateral) activities (and also OSTP, by the way). “Blockade” implies a US iron ring around China preventing others from coming/going on space matters; & that’s not true. It’s about US components et al not being allowed to be part of any systems launched on Chinese rockets (etc.). That’s simply the US refusing to participate in bilateral space trade vis a vis China; hardly a ‘blockade’, ok? (Words matter; tho, I wouldn’t be surprised if that’s the word the CCP uses).
2. Going forward: Some of the countries that have signed on to participate with China in space have also signed the Artemis Accords- a voluntary, international code of behavior, consistent with the Outer Space Treaty, that, among other things, requires transparency in things like lunar activities. (It was that requirement in the AA for transparency that led several years ago for Russia to pull out of the tentative agreement to join the Artemis program). Now, the PRC is not known for its commitment to transparency. Yet, several of its now space partner countries have signed the AAs, which require it. It will be interesting to see if those countries do indeed cave in to normal PRC behavior for less-than-fully transparent operations - as you can tell, I’m afraid I consider that likely- or rather maintain their signed commitment to the AAs and transparency when it comes to lunar exploration and development. (It should be kept in mind: tho they have similar names, there is NO legal connection between the Artemis Accords codes-of-behavior, and NASA’s Artemis Program. India & Saudi Arabia have both signed the AAs; they are not part of the Artemis Program). - Dave Huntsman
Addressing your two points:
1. You didn't even watch the video before you replied, did you? 10:04 in the video literally told you the "blockade" nature of the US policy against China. Did you not see it or did you just ignore it?
2. Your Western brainwashed bias against China is so blatant it's hilarious to watch. To criticize China's transparency record while every country in the world has state level secrets is simple double standard. The US alone has three levels of security clearance throughout it's entire government: confidential, secret, and top secret. You just say China lacks transparency because when China doesn't tell you everything you want to know, it's China lacking transparency. When US or other countries don't tell you their state secrets, it's national security.
Double standard at it's finest 😂
So it's not a blockade, but a one-way self-imposed isolation from collaborating with China, based off of suspicion and xenophobia. That makes sense
USA’s signature on any agreement is not worth the paper it’s written on. Native Americans learnt that long ago. The Vietnamese learnt that in 1972. Russia learnt that in the Kiev Accord. Transparency in U.S. government ? Go as Julian Assange, Edward Snowden, Chelsea Manning, Robert Hayes, Daniel Ellsberg, etc.
Western technology 😂😂😂
@@alandashcar1453 western technology is the best 😂😂😂 propaganda technology
I suspect both ways. U.S. and China. China definitely did gain valuable technology at crash site. US most likely did sabotage the launch but to what extent? No one knows
The USA is now inviting China to participate in the ISS/Artemis, but first China must condemn Hamas.
The US has a long way to go, there are 140 other UN countries on the wait list.
LoL😂
With the current progress of the two projects, I think it is easier for China's plan to become a reality, especially since Shenzhou 17 is the 30th successful mission.
