"Artemis" has been postponed again, and it is very trending to catch up with the first Ace Pigeon Weber telescope. Why is it even more difficult for the United States to land on the moon again?
The plan for the title of the Moon Goddess is unfulfilled, and people can't help but have doubts about the American moon landing .
film and television dramas spoof the United States' moon landing and fraud
plus Chang'e-5 landed on the moon before, the flag was different from the United States' moon landing. The flying flag of the United States made people feel very fake.
So, why did the American flag flutter back then? The moon has no atmosphere and no wind, is it really shot in the studio?

Different flags
Apollo 11's feat has been written into history books, and Armstrong's famous saying has also become a word that people engrave in their minds.
However, together with this feat, there is also the suspicion of moon landing . The authenticity of lunar landing has been discussed, because other countries do not have manned landings on the moon, and people cannot truly compare it.
People from other countries did not go up, but the national flag was up. my country's Chang'e-5 front feet held the flag-raising ceremony on the moon. Before the ceremony ended, netizens around began to compare .
Chang'e 5 Flag-raising
Compared with the large-scale national flag of the United States back then, my country's national flag is relatively small, and the has a very hard texture, basically no unnecessary fluttering .
comparison videos can be found that The American flag actually fluttered , which is impossible on the moon because there is no atmosphere on the moon, and there is no so-called wind.
So, why does the American flag float? Is it because it is fake?
In this regard, NASA's explanation is that the US flag is manually installed by the astronauts. After installation, the flag shakes.
The flag of the United States flutters
Without air resistance, the shaking of will continue , so people will see the flag fluttering in the video.
and 's flag material is actually similar to plastic film . It was rolled up in advance and placed in a corner of lunar module . After is expanded, there are wrinkles on it, which looks more like it is floating.
In order to fully expand the flag of the United States, the American flag was adopted to use an "F"-shaped bracket , and the national flag was put on it to spread.
Astronauts are installing flagpole
There are still many people who don’t buy this explanation, but there is no way to prove the authenticity. After all, with the progress of the times, the materials are getting better and better, and it is impossible to use the materials from that year.
Even if there are other countries in the future manned landing on the moon, it will be difficult to simulate this situation.
It seems that the US moon landing is going to become a unsolved case and has been suspected.
In addition to the national flag flying, there are still several doubts in the United States landing on the moon.
The first person to land on the moon, Armstrong
There are many doubts
First of all, it is not on the moon, is completely weightless , has 1/6 of gravity on it. Logically speaking, astronauts can jump on it and jump to 3 or 4 meters altitude .
But in fact, astronauts did not jump high, only a few dozen centimeters from the ground , which was no different from the height of jumping on the earth. It is not difficult to suspect that they jumped on the earth.
Regarding the height of jumping, this cannot be completely based on theoretical values. You should know that is a very heavy , especially this kind of space suit that is active outside the cabin, which has 120 kilograms of weight .
Astronauts move on the moon
No matter how agile astronauts wear this outfit, they will be unable to move. When the astronauts wear this outfit on the earth, they can basically only move, and they can only jump up under gravity 1/6 .
From this perspective, it can only jump to a height of tens of centimeters.
Some people may say that the lens can be used to hang with a wire, and it cannot completely clear the suspicion of the studio.
Regarding gravity and vacuum, the dust raised by rover and astronauts can be verified.
Outdoor space suit
We all know that if dust is raised in the environment of the earth, then will be filled with dust , so everyone is most afraid of encountering dump trucks on the road.
But on the moon is a vacuum and only 1/6 of the gravity . After the dust rises, it will fall slowly vertically and will not fly everywhere because there is no air medium or air flow.
If you want to simulate such a scene on the earth, needs to create an environment of vacuum and 1/6 gravity . The vacuum is OK and can drain the air, but 1/6 gravity is basically not possible.
lunar rover dust
and first landed on the moon in 1969 . At that time, Hollywood 's special effects technology was not as strong as fake . The animation was still hand-drawn, and it was impossible to synthesize it through computers.
From this point of view, it does not seem to be fake.
and also about why no stars were photographed in the moon's sky. This can be found in other astronauts space walk .
The background of astronauts' space walking, is often a dark universe , but according to the astronauts' own description, they can actually see the stars. The moon's sky taken by
cannot be seen in the lens because the sun is too bright, it covers the light of these stars , causing the entire lens to be overexposed.
When landing on the moon, it must be the daytime on the moon, and the moon's rotation is very slow, lunar day = 28 earth days .
Armstrong and his colleagues stayed on it for more than 10 hours, and only took about 2 hours to walk in space. Basically, has always been the daytime of the moon, and there is no star shooting at all.
As for why everyone is puzzled about why they cannot return to the moon, is actually because the US moon landing system has long collapsed .
Astronauts only walked for about 2 hours

The reason why the "Artemis" was postponed many times is that there were problems with parts. Why so many problems?
Because most of the factories and enterprises that planned to produce parts for Apollo that year were no longer able to work!
They have either gone bankrupt or changed careers to other s, so NASA restarted the plan, but found that even the Rockets could not be built.
The United States’ aerospace industry is different from the integration of my country , and NASA is not responsible for research and development, production, assembly and launch in one-stop.
NASA Command
NASA first formulates a plan, then engineers design drawings, and then conducts tests. The parts and equipment in it come from orders placed to each factory in advance.
Many companies only produce a certain type of parts and only issue orders. Although they are private companies, is equivalent to the relationship with NASA as a partner .
Because of the Cold War , , , Boeing had a production line for NASA , for no other reason, because you can make money.
During the Cold War, aerospace accounted for 2% of the national GDP. With NASA, many companies in Silicon Valley have made a lot of money.
The Cold War Space Battle at that time
It can be said that NASA revealed three words all over his body at that time - is not short of money !
is not just moon landing plan , but also the Voyager series of probes, several Mars rovers and space shuttle , each of which is a big money burner.
After the end of the Cold War, NASA lost its old enemy, Soviet aviation , and the United States also began to reduce aerospace expenses, , which led to NASA's funding becoming less and less .
The space shuttle
, which have all been retired, saw that this industry had no prospects, so closed down and changed career , and almost all the manufacturers responsible for producing the Apollo plan, the Voyager plan, and the Space Shuttle plan were no longer there.
is like this, it is already difficult to produce the "Artemis". It is not new to if there is a failure in .
NASA In order to obtain sufficient funds on "Artemis" plan , used the "Chang'e Plan" to promote the threat theory to stimulate the US authorities, and thus received some funding.
NASA repeatedly promotes the threat theory
The future of the moon
is obvious. With the implementation of my country's moon landing plan one after another, the situation where the United States enjoys the moon alone will become a past trend.
There will be my country on the moon in the future. who will build the moon base first seems to have become an unknown number .
my country has repeatedly emphasized that the purpose of the "Chang'e Series" moon landing plan is to research . Unfortunately, the United States does not think so. They hope that they will always occupy the moon, even if they do nothing.
my country's Chang'e plan
It is obvious that this is contrary to the direction of the historical river, because technology is moving forward, so are the country.
Thinking back to the past, we carried out various experiments with only 1 gram of lunar soil with arduous efforts. After the success of Chang'e 5, our country has more than 81,700 grams of lunar soil sample .
From then on, our research on the moon will go to a higher level, and we don’t have to worry about not enough. If we still need it, then we will go to the moon again and bring back more samples.
The future moon base
Anyway, we have matured the lunar landing technology, so we just need to send one person up.
