The Chinese flag displayed by Chang'e-6 on the far side of the moon is not ordinary, it is hidden in Xuanwu and can remain immortal for tens of thousands of years.
The Chinese flag looks very flat, because there is no wind on the moon, so the flag does not flutter.
Strangely, the American flag of 50 years ago looked undulating, wasn't everyone on the same moon?
The mystery of the American Apollo moon landing
On July 20, 1969, the Apollo 11 spacecraft successfully landed on the surface of the moon, and two astronauts, Armstrong and Buzz Aldrin, set foot on lunar soil and planted an American flag.
Mankind's dream of lunar exploration has become a reality.
But just over half a century later, when China's Chang'e-6 probe landed on the far side of the moon and raised the brightly coloured five-star red flag, a puzzling detail was noticed: unlike the fluttering posture of the American flag, the Chinese flag presented a calm and peaceful scene.
The status of the two flags has led to a conspiracy theory that has recently become popular around the world - the Apollo moon landing hypothesis.
Many people suspect that the Apollo moon landing program was a hoax, and there are three main arguments popular among them.
First, the fluttering national flag.
The Moon has no atmosphere, and scientific common sense tells us that there can be no natural phenomenon such as "wind" in an environment without air.
So, since there is no wind on the moon, how can the American flag be fluttering?
Second, clear footprints.
Some scientific and technological people analyzed that the quality of the photos of the moon released by the United States was too fine and the details were too perfect, which just exposed traces that may have been post-processed by computer technology.
Even nowadays, few countries can take such clear pictures.
Third, the shadow that something is wrong.
Why does an astronaut have two shadows, and why astronauts with different heights have the same shadows?
Many netizens believe that this is because the scene of the moon landing was shot in the studio at all, and it was also processed with film and television special effects.
This skepticism continues to this day. In 2013, a former CIA employee publicly declared: "Russia is the first country to successfully land on the moon." "
In 2018, the famous billionaire took to Twitter to question the "computer microscopy" technique used to make the Apollo project's film.
"It must have been difficult, because computers weren't advanced enough at the time, and space travel required a lot of technology."
Even today, a manned landing on the moon is an extremely complex task, and even the United States cannot repeat the Apollo program in a short time.
What Chinese scientists think
Despite the popular discussion, scientists in the Chinese astronomical community, including the team that made the Chang'e rocket, recognized the authenticity of the Apollo moon landing.
Why is that? It's simple, because we got 1g of lunar soil from the United States.
The first step in the beginning of continental aerospace began with the samples and data that Russia and the United States gave us.
At that time, we did not have the ability to go to heaven ourselves, and the samples and data shared by the United States and the Soviet Union were our only source of information.
And what if, the samples that the United States distributed to the whole world are also fake, they are manufactured? We haven't been to the moon, so what if we get scammed by them.
Don't be afraid, after China landed on the moon itself, it personally collected samples and immediately compared them with American samples.
It turned out that the composition was indeed exactly the same, and if they had not landed on the moon, it would not have been possible to create lunar soil on Earth.
Academician Ouyang Ziyuan, the father of Chang'e, believes that even with the current level of science and technology, replicating lunar soil is still a very complicated, difficult to complete, and costly experiment.
It is impossible for the United States to restore the lunar soil before it landed on the moon. It costs no less to replicate lunar soil than to build a rocket.
Samples given to China by the United States and the Soviet Union are still part of China's lunar research.
The Soviet Union harvested 3 billion years, the United States harvested 2 billion years, and China harvested 1 billion years of soil.
Of course, there is a secret part of the technology in each country, but the basic data is shared throughout the astronomical community.
NASA actually has decades of experience exchanging data with China, and they used to give us data, and now we share it directly with the world.
We did not specifically target and exclude the United States, but it was their parliament itself that came up with a bill that would not allow the space agency to communicate with China.
Closing the country to the outside world does not bring progress, only backwardness, and obviously the Americans do not understand this truth.
As for the fluttering of the flag, it is not contrary to science.
Because NASA did not deliberately prepare a special flag back then.
This American flag was bought and brought by the astronauts themselves for 9.9.
So they didn't have a special place to place the national flag at all, and the poles were also found temporarily.
The material of the flag is very poor, and the fabric is very thin.
The astronauts' action of inserting the national flag creates a certain inertia, and there is no wind and no air resistance on the moon, so the national flag will continue to fly.
The strength of the bamboo pole to fix the national flag is simply not enough, and it will be distorted and deformed due to gravity and other reasons, which will affect the hanging state of the national flag.
As for the shadow, the problem is actually caused by the specular reflection of the light source on the lander, coupled with the uneven surface of the moon.
Now, after so many years, under the continuous radiation of the sun, this Star-Spangled Banner should have long since become a white flag of surrender.
Therefore, when our scientists displayed the Chinese flag, they also deliberately referred to the failure experience of the American flag and deliberately avoided these shortcomings.
There are two main problems we solve, one is the folds caused by inertia, and the other is the fading caused by radiation.
Xuanwu flag
We need to know that the lunar environment is extremely harsh. Without the protection of the atmosphere, the surface of the moon is exposed to various threats such as cosmic rays and asteroid impacts.
The national flag carried by Chang'e-6 is made of special fiber materials that are UV-resistant, high-temperature-resistant, and rigid, and specially designed to be in a straight state.
They chose a special volcanic basalt fiber as the main material for the flag.
The fiber itself also contains a large number of tiny closed pores, which makes it an excellent cushioning effect, which can effectively defend against space dust and prevent damage to the national flag.
What's more, the extremely stable physicochemical properties of volcanic basalt ensure the long-term durability of the entire fiber.
We actually made the stone into thread, and the whole flag was made of basalt fibers.
Because there is basalt on the moon itself, it proves that this material can adapt to the lunar environment and exist on the moon for a long time.
Experts estimate that as long as it does not suffer too much external impact, the service life of this national flag can even be as long as tens of thousands of years.
More than 60 percent of the flag is basalt, and the rest is aramid, and the two are woven together to make a flag that is slightly smaller than A4 paper.
The harder material and smaller area ensure that the flag can be flatter in space.
From the first orbit around the moon, to record-breaking lunar sampling, and now to the far side of the moon, the continent has become a leader in the new era of space.
