Preface
Thanks to the efforts of countless people working day and night, China's aerospace industry has developed more rapidly and maturely, and now it is also in the forefront of the world and is a force to be reckoned with.
From the Shenzhou-1 non-manned test to the Shenzhou-18 manned spacecraft, from the initial exploration of the moon to the establishment of the space station, from Chang'e-1 to Chang'e-6, which will be launched this year, and so on.
All these efforts and achievements have been witnessed by countless people, and the words "successful launch" seem to have become a matter of course.
However, we have not succeeded in the field of aerospace every time, and we have experienced countless failures, suffered countless ups and downs, and even some failures brought devastating blows.
There was a situation where two rocket launches failed in a row within a month, and the high risk of the aerospace industry was also undoubtedly revealed in those two failures.
Failure after failure
It is said that everything is difficult at the beginning, and in the development of the mainland's aerospace industry, this sentence is obviously very applicable.
As early as when China was not fully developed, we have understood the importance of the aerospace industry, so countless scientific researchers are constantly exploring and working hard in this field.
Of course, failure is inevitable, and failure after failure means re-"zeroing", a word that almost everyone who is engaged in aerospace has changed their faces.
But sometimes, the reasons for failure are also unforgettable.
November 5, 1974 was the day of the launch of the Long March-2, and with the success of the Long March-1 ahead, everyone was full of confidence in this launch mission.
But no one expected that as soon as the rocket was launched, there was a sudden violent swing and it suddenly lost its balance.
Immediately after launch, 20 seconds after launch, the rocket suddenly exploded, leaving only debris and debris all over the ground, and all the astronauts' hard work for three years of research and development was destroyed in one fell swoop.
Many astronauts who witnessed all this couldn't help crying, but everyone didn't have time to immerse themselves in grief at all, but quickly investigated the cause of the failure.
In the end, after sleepless investigation, everyone found the reason, and no one expected that the culprit who caused the failure of the rocket launch was actually caused by a small broken wire.
It is precisely because of this failure that everyone is more deeply aware that the development of rockets really cannot make the slightest mistake, but sometimes accidents are still inevitable.

In the early morning of February 15, 1996, the Long March-3B rocket, newly developed by the mainland, began its flight test.
However, just about 2 seconds after takeoff, the rocket was abnormal, and the direction of flight was obviously offset, but at this time, there was nothing everyone could do to save it.
Everyone present was nervous and watched as the rocket flew for about 22 seconds before crashing directly into the nearby hillside two kilometers in a head-on.
The ensuing violent explosion and impact affected the surrounding people, directly killing 6 people and injuring 57 people of varying severity.
It was the worst defeat of all, and the damage and tragedy caused by the failure were incalculable, and the chief designer of the rocket turned gray almost overnight.

Everyone paid a huge price for this failure, but they could not stop there, everyone knew that failure could not be avoided, and they could only minimize the probability of failure.
The lessons of failure after failure have made many astronauts cautious and strive to make breakthroughs, and our aerospace industry has also developed faster and faster.
But I didn't expect that when everyone thought that the motherland's aerospace technology was becoming more and more mature, in 2020, there was another rocket launch failure, and it was two consecutive failures.
Two launches failed in 30 days
On March 16, 2020, the Long March 7 medium-sized launch vehicle launched its first mission.
The Long March 7 was the latest generation of carrier rockets newly developed by the mainland at that time.
Before the rocket was launched, everyone was on standby, and the rescue team was ready and ready to be outside at any time.
At that time, the rocket engine ignited normally, and after its successful lift-off, everything went according to the established theory.
But when everyone breathed a sigh of relief and returned to the accusation hall to observe, they received the news that the rocket's flight curve was wrong.
168 seconds after liftoff, the rocket crashed directly into the Pacific Ocean, where all the relevant test team members gathered to seriously discuss where the problem came from.
It was a rocket that everyone had worked hard to develop for more than half a year, and everyone was extremely heartbroken.
At that time, the designer of the rocket said that the moment the rocket crashed, she felt that she had half a year of life left.

However, this side has been stepping up the investigation into the cause of the failure of the Long March 7 rocket, and the launch vehicle on the other side has also had an accident.
On April 9, 2020, the LM-3B launch vehicle was also faced with an important task, which required the successful launch of the Indonesian PALAPA-N1 satellite.
It is also a relatively mature launch vehicle, and the Long March 3 should not have any serious problems, but it backfired.
After the rocket was launched, the first and second flights were normal, but the third stage was detected by the ground data and the abnormal situation, and before it could react, the rocket had failed and fell, leaving only wreckage.

The failure of two consecutive rocket launches has caused China's space industry to suffer a lot of blows and losses, but at the same time, many people are also puzzled, how could things be so coincidental?
The most important thing is that both rockets are supported by very accurate data, especially the Long March 3B rocket, which has a wealth of successful experience.
At that time, many people were talking about this matter, and some Taiwanese media even claimed that this was because the United States strengthened the control of chip exports, and we lacked American chips, which ultimately caused the rocket launch to fail.
Aviation Knowledge2020-04-19"China's Two Rocket Launches Failed in a Month, Due to the Lack of American Chips?"
Of course, this kind of statement is not credible, and the researchers finally found the reason in themselves, and finally found the problem.
The failure of the Long March 7 is most likely caused by the failure of the power system, and the failure of the Long March 3B is caused by engine problems.
Finding problems, solving problems, and avoiding problems, researchers resist the pressure under failure and strive to make the next rocket better.
In the midst of failure after failure, they have found the right direction and gone further and further, and our aerospace industry has become more and more mature.
Failure makes people progress, no matter what blows we suffer, we will not stop moving, and I believe that in the future, our aerospace industry will go further, and we pay tribute to every aerospace worker.
