China’s Long March 7A rocket had a near-perfect record: 16 successful launches in a row. Then, 85 seconds after liftoff, it exploded.
Why did one of China’s most trusted rockets suddenly fail? And why did it happen during a record-breaking push to speed up launches? In this program, we look at five unusual details behind the disaster—and the much bigger political story surrounding it.
China’s Rocket Force has been purged. Aerospace executives and research chiefs have fallen. And Ma Xingrui, one of the most powerful politicians to rise from China’s space industry, was officially taken down just weeks before the launch.
Was this simply one bad rocket—or a warning that something deeper is breaking inside China’s aerospace system?
On August 10th, China launched one of its most trusted rockets from Wenchang.
The Long March 7A had already flown successfully 16 times in a row.
This was supposed to be routine, but the rocket exploded.
And what makes this story interesting is not simply that China lost the rocket,
it's what was happening around it.
The launch was part of a record-breaking push to shorten turnaround time.
The rocket was carrying an extremely valuable communications satellite.
The failure could potentially affect other major Chinese space missions.
And behind all of this, the aerospace establishment that built China's space program
has been going through one of the biggest political purges in its history.
Military commanders have fallen, aerospace executives have fallen,
research institute leaders have fallen.
So tonight, I want to take a look at five unusual things about this rocket failure.
And then I want to show you why this explosion may tell us something much bigger
about what's happening inside China's aerospace system.
First things first, what had happened?
On the night of August 10th, at the Wenchang Space Launch Site in Hainan,
a Long March 7A rocket carrying the ChinaSat-4B satellite roared into the sky.
About 85 seconds later, the rocket broke apart.
Three hours later, Xinhua confirmed that the flight had experienced
an abnormality and the launch mission had failed.
Then overnight, videos of the explosion began disappearing from Chinese short video platforms.
They were censored.
Now, rocket failures happen.
Space flight is dangerous.
Even mature programs lose rockets.
But when you look closely at this particular failure, there are five things that stand out.
Number one, this was a mature rocket.
The Long March 7A was not an experimental vehicle.
Its first flight failed in 2020.
But after that, it completed 16 consecutive successful launches.
16.
By this point, it had become one of China's main rockets
for sending large satellites into high orbit.
So when a rocket with this kind of record suddenly breaks apart,
the obvious question is, what changed?
Number two, it failed at a very sensitive moment.
The rocket broke apart about 85 seconds after liftoff.
That timing matters.
Around this stage of flight, a rocket is moving extremely fast
while still pushing through thick atmosphere.
Engineers call this max Q.
You don't need to remember the technical term.
Just think of it as one of the moments when the rocket is under enormous physical stress.
So if a mature rocket breaks apart around this point,
investigators will naturally be looking very closely at structural failure,
engines, boosters, or other major systems.
What changed inside a system that had already worked 16 times?
Again, we do not know the answer or the cause.
But 85 seconds is not a random number.
Number three, they were pushing the launch schedule.
This may be one of the most interesting details.
Just 12 days earlier, on July 29,
another Long March 7A had launched from the same site at Wenchang.
Before the August mission,
Chinese state media openly celebrated the fact that this would set a new record
for the shortest turnaround between launches for this rocket
and even for China's new generation of Long March rockets.
Now, faster launches are not automatically dangerous,
but there is an important difference between China and companies like SpaceX.
SpaceX frequently reuses the same basic rocket hardware.
China's Long March rockets are expandable.
Every launch means a newly assembled rocket made from thousands of components
that all have to be tested, checked, and verified again.
So when the system starts pushing for shorter and shorter turnaround times,
a reasonable question appears.
Did the pressure to break a record also increase pressure on testing,
quality control, and personnel?
Maybe China's launch system simply became more efficient.
But there's a question looming.
Was this another political-style great leap forward,
an attempt to win a record for the sake of winning the record?
But after a failure like this, the timing becomes impossible to ignore.
Number four, the payload was extremely valuable.
This was not a small experimental satellite.
The rocket was carrying China's SET-4B,
a major communications satellite built on the Dongfang Hongfour platform.
This is a large, expansive satellite platform
designed for long-term communications missions.
It can also support highly secure, long-distance communications.
So the loss was not just one rocket.
It was the rocket plus a major satellite
that may have cost 1.5 billion yuan to develop and build.
Some estimates put the total direct and indirect losses
from the failed mission as high as 3.2 billion yuan.
Whether that exact figure is correct or not,
one thing is clear, this was an extremely expensive failure.
Number five, the problem may not stop with this rocket.
And this may be the most important point.
The Long March 7A shares major technologies and components
with other rockets in China's new generation of launch vehicles.
So if investigators find that the failure came from something specific to this one rocket,
the damage may be limited.
But if they discover a problem involving an engine, component,
production process, or quality control system used across other rockets,
then the consequences could spread much further.
China has a failure review process known as double zeroing.
Basically, investigators have to answer two questions.
What technically went wrong?
And also, who was responsible for allowing it to happen?
That means this investigation is not only about engineering,
it's also about management and accountability.
And if the problem involves technology shared by other launch vehicles,
upcoming missions could potentially be delayed
while engineers inspect the rest of the fleet.
One mission to watch is Chang'e 7, China's next major lunar mission.
Its spacecraft and rocket have already been moved to Wenchang
ahead of a planned launch later this year.
So one failed launch could potentially create a much larger ripple effect.
Put these five things together,
a mature rocket with 16 straight successes suddenly fails.
It breaks apart at a critical moment in flight.
The launch came during a record-setting push for faster turnaround.
An extremely valuable communication satellite was destroyed.
And investigators now have to determine
whether the problem could affect other rockets and other missions.
That is why this failure deserves more attention.
Than any ordinary launch accidents.
But there is another reason.
Because behind this rocket is an aerospace establishment
that has been going through an extraordinary political purge
for the past three years.
And once you look at what has happened to the people
who built and managed China's space program,
this explosion starts to look very different.
To understand the political fallout, we need to go back to 2012,
the year Xi Jinping took power.
Now, at the time, many senior technocrats
were linked to older political networks,
particularly the Jiang Zemin faction.
Xi Jinping began tearing those networks apart.
That created a new problem.
Who would fill the positions left behind?
One answer was the aerospace establishment.
From 2012 onward, a large number of senior officials
with aerospace and military industrial backgrounds
were promoted into major political positions.
The logic was very simple.
These people were technically capable.
They were used to secrecy, discipline, and political missions.
And most importantly, many of them didn't have
strong local political bases of their own.
Their rise depended heavily on the central government.
That made them useful to Xi Jinping.
And very quickly, China's aerospace giants became political incubators.
The most important name was Ma Xinrui.
Ma was one of China's most famous aerospace technocrats.
He had served as general manager and party secretary
of China Aerospace Science and Technology Corporation.
He had also been involved in China's manned space program
and the New Generation Launch Vehicle program.
Then he moved into politics.
Shenzhen party secretary, governor of Guangdong,
party secretary of Xinjiang,
and in 2022, a member of the Politburo.
Then there was Zhang Qingwei.
He also came out of China Aerospace Science and Technology Corporation.
He later became governor of Hebei and party secretary of Heilongjiang.
Yuan Jiajun is another such technocrat.
He came from the Shenzhou spacecraft program.
He later led Zhejiang, moved to Chongqing, and entered the Politburo.
Xu Dazhe came from China Aerospace Science and Industry Corporation
and later became party secretary of Hunan.
At its peak, the aerospace system
had become one of the clearest political pipelines into China's top leadership.
But that created a dangerous incentive.
If running a rocket program could become a path to running a province,
or entering the Politburo,
then engineering success was no longer just an engineering matter.
It became political capital.
And by 2023, the system began to unravel.
The first major shock came from the rocket force.
Commander Li Yuchao disappeared.
Former commanders Zhou Yaning and Wei Fenghe later fell as well.
Even the newly promoted rocket force commander Wang Haobing,
who replaced Li Yuchao, was later removed as well.
The leadership of one of China's most important strategic military branches
was completely torn apart.
Then the investigation moved backward into defense procurement and aerospace.
In December 2023, Wu Yansheng,
chairman of China Aerospace Science and Technology Corporation,
lost his CPPCC membership.
The same day, Liu Shiquan,
a former head of China Aerospace Science and Industry Corporation, was also removed.
So was CASIC deputy general manager Wang Changqing.
In January 2024, Wang Xiaojun,
former head of the China Academy of Launch Vehicle Technology,
also lost his CPPCC membership.
That name matters.
The China Academy of Launch Vehicle Technology,
which is called the First Academy,
is the organization that developed the Long March 7A.
Then in April 2024, Yuan Jie,
chairman of China Aerospace Science and Industry Corporation,
disappeared from public view and was removed from his post.
In August 2024, Dai Shaolun,
a former head of the Shanghai Academy of Space Flight Technology,
who had moved into local government, came under investigation.
In October 2025,
former Hunan Party secretary Xu Dazhi was removed from his position
on the National People's Congress Standing Committee,
and the purge did not stop with aerospace.
From the second half of 2023,
central inspection teams moved into around 30
major state-owned defense enterprises
covering weapons, aerospace, aviation, shipbuilding, and electronics.
Wu Wenming, the former chairman of China Shipbuilding Industry Corporation,
was sentenced to 13 years in prison for corruption.
In October 2024, Xiao Longxu, a former rocket force chief engineer
and member of the Chinese Academy of Engineering,
also lost his CPPCC membership.
Then the storm reached the very top of the military.
Central Military Commission vice chairman He Weidong
was expelled from the party in October 2025.
And then later, in January 2026,
another vice chairman, or the other vice chairman, Zhang Youxia, was detained.
By then, this was no longer a normal anti-corruption campaign.
Large parts of China's military and defense industrial leadership had been shaken.
But the most symbolic fall came in 2026.
Ma Xinrui had already been removed as Xinjiang Party secretary in July 2025.
At first, Beijing only said that he would receive another appointment.
Then, April 3rd, 2026, Xinhua announced that Ma was under investigation.
Three months later, he was expelled from the party and removed from public office.
That was a major political moment because Ma was not just another aerospace official.
He was one of the clearest symbols of Xi Jinping's decision
to promote aerospace technocrats into the political elite.
He was a Politburo member, one of the top 24 CCP leaders, and a close ally of Xi Jinping.
And around the same time, officials linked to Ma in Guangdong, Xinjiang, and Heilongjiang
also began falling one after another.
One person went down, then the network around him started coming apart.
So if you step back, the political timeline is remarkable.
After 2012, Xi Jinping elevated aerospace officials because they looked competent,
disciplined, and politically reliable.
They became governors, party secretaries, and Politburo members.
Then came the rocket force scandal in 2023.
The investigation spread into procurement, into aerospace corporations, into research institutes,
into provincial politics.
And by 2026, Ma Xinrui, the most recognizable political star of the aerospace establishment,
had fallen too.
Now bring the camera back to August the 10th.
Less than a month after Ma Xinrui was expelled from the party,
a Long March 78 rocket lifted off from Wenchang but failed.
It was developed by the first academy, which is the institution,
already touched by the massive purge.
The rocket had succeeded 16 times in a row.
It was supposed to help set another turnaround record.
Then 85 seconds after launch, it broke apart.
Officially, we still don't know the technical cause.
And we should not pretend the political purge directly caused the rocket to fail.
Those are two separate questions.
But the symbolism is hard to miss.
A system once held up as proof of China's technical competence and political discipline
is now under investigation from top to bottom.
Its military commanders have fallen.
Corporate leaders are gone.
Academy heads have fallen.
Political stars have fallen.
And now one of the most reliable rockets has exploded in the sky.
So the question is not just what failed inside that rocket.
The real question is, what is failing inside the system that built the rocket?
Because if the problem is not one engine, one component, or one bad launch,
but a deeper breakdown in management, in quality control, in morale, in political incentives,
then this may not be something China's aerospace industry can fix quickly.
And that may be the real significance of the rocket failure on August 10, 2026.
