When seeing our country's national flag on the moon and the United States' national flag, the United States was questioned by netizens again.
is right, this is not the first time, but many times.
Why is the US moon landing repeatedly suspected?
The first time humans landed on the moon was on July 20, 1969. Apollo 11 successfully landed on the moon, and astronauts Neil Armstrong and Baz Aldrin also became the earliest humans in the world to land on the moon.
No survivable lunar organic matter was found after landing on the moon, nor was there any evidence of ancient microorganisms. , but based on the isotope analysis of the sample, the lunar age was about 4.6 billion years.
21st century, what humans yearn for is the universe more, and most people want to walk on the moon.
Now that it is 2022, half a century has passed, and since the United States' manned moon landing program came to an abrupt end in 1972, there has been no activity.
and then people have been suspected that they were fake on the moon, and was only shot in the studio of Hollywood . because many people really don’t believe that the technology at that time could really reach the moon.
What is this happening?
Among them, many people think that the Apollo moon landing solution is not very reliable, and its security in is less than 50%. In addition to Artemis 1, pigeons and pigeons, many netizens in are increasingly distrusting the authenticity of Apollo's moon landing.
The most "surprise" of conspiracy theorists is that when Armstrong planted the American flag, the unfolded flag looked like it was fluttering in the wind.
Why does the American flag on the moon seem to be flying?
Many people say that there is neither wind nor air on the moon, so why does it float? However, the flags unfolded on the moon surface of my country's Chang'e-5 on the moon are very flat.
can't make any explanation now.
Is the moon landing in the United States fake?
In fact, Apollo moon landing is real.
First, the United States has invested huge manpower and material resources in the Apollo program;
The Apollo program began in May 1961, and the sixth moon landing from to December 1972 successfully ended. It lasted about 11 years and cost US$25.5 billion.
accounts for about 0.57% of the United States GDP that year, and about 20% of the total US scientific and technological research and development funds that year. Provides amazing long-term employment growth.
At the peak of the project, there were 20,000 enterprises, more than 200 universities and more than 80 scientific research institutions participating in the project, with a total of more than 300,000 people.
Second, the United States has obtained a large amount of lunar soil through the Apollo program;
The United States landed on the moon six times in the past and brought back a total of 382 kilograms of html April rock . At that time, the United States also gave my country a sample of 1 gram of lunar soil. is this 1 gram of lunar soil, which kicked off the moon landing project in my country.
This 1 gram of lunar soil is really too precious. We cannot use it completely for research. scientists break it into two parts, half for placement in museums for people to watch, and the other half for scientific research.
The United States gave us 1 gram of lunar soil. In the past, I needed to magnify it with a magnifying glass.
Nowadays, my country's Chang'e-5 has successfully brought back 1,731 grams of lunar soil from the moon. can see whatever you want. We have undoubtedly made progress in this regard.
The American flag on the moon can fly, In fact, when they designed the national flag, they took into account the windless conditions of the moon.
Therefore, the flagpole of the national flag is designed to look like the number seven. The national flag is not only connected to the flagpole on the side, but also to the flagpole on the top, so it will be unfolded after assembly.
looks wrinkled like it is floating in the wind. is actually because its sides are not fixed, so it is difficult to spread flat. On the one hand, should consider the material of the national flag.
Speaking of material issues, it is actually very cheap. costs only US$5.5. It is made of ordinary nylon, and its tolerance is limited in extreme temperature environments.
The most prominent advantage of its wear resistance is that it is higher than all other fibers, 10 times more wear resistance than cotton and 20 times more than wool. Adding some polyamide fiber to the blended fabric can greatly improve its wear resistance; when stretched to 3~6%, the elastic recovery rate can reach 100%; it can withstand tens of thousands of twists and continuous cracking.
But our country's national flag is different. It is made of a new composite material that is resistant to high and low temperatures, radiation and ultraviolet rays, and can keep it bright on the moon.
How much temperature changes on the moon’s day and night are, I think everyone knows.
The temperature at night is minus 200℃, and the surface temperature during the day can reach 150℃. Under such extreme conditions, how can nylon bear it?
In fact, when Armstrong and Aldrin inserted the flagpole, they found that the surface soil of the moon was relatively hard, so they applied greater force, which also caused the flagpole to have a pendulum effect.
