<h1 class="pgc-h-arrow-right" > preface</h1>
The development of human science and technology in the 20th century was faster than at any time in history, and modern physics has developed rapidly under the guidance of quantum mechanics and relativity, breaking through the category of classical physics and coming to the universe.
After the Industrial Revolution, human life has undergone great changes, human productivity has advanced by leaps and bounds, and the United States and the Soviet Union, as competitors, have also begun their initial exploration of the universe early.
The two superpowers have invested a lot of manpower and material resources in the space race, and they want to land on the moon one step ahead of each other to occupy the absolute dominance of the superpowers.
With the Soviet Union's defeat in space, the United States came to the forefront and became the number one pioneer in space exploration. 52 years ago, the "Apollo Moon Landing Program" launched in the 1960s first sent humans to the moon and landed, which brought great influence to the world. Since then, the United States has also dominated aerospace for a long time.
<H1 class="pgc-h-arrow-right" > the Apollo moon landing program</h1>
The name of the Apollo project comes from the ancient Greek myth of the sun god, in which Apollo, as the brother of the moon god, killed the python with a golden arrow to avenge his mother. The choice of this name is also the U.S. government's desire to wash away the shame in the previous defeat with the Soviet Union.
It is reported that at that time, NASA prepared four auxiliary missions for the lunar landing program, mainly to take pictures and analyze the moon in lunar orbit and detect suitable landing sites and landing positions. Astronauts are trained in docking, extravehicular activities, etc., in order to ensure the smooth progress of the lunar landing mission as much as possible.
However, in the flight test of the space shuttle, the failure of Apollo 1 caused the sacrifice of several astronauts, and the astronauts who died of poisoning in the return test brought a lot of pressure to the mission. Before the Apollo program began, the Soviet Union had already sent humans into space, and the U.S. government began to work the launch of Saturn 5 with the expectations of the American people under a lot of pressure.
During the 11-year mission, the United States finally accomplished this feat with national effort. Astronaut Armstrong left human footprints on the moon and planted the American flag on the moon, saying a phrase that is familiar to all mankind, "My small step is a big step for human civilization."
<h1 class="pgc-h-arrow-right" > task impact </h1>
The success of the Apollo moon landing program gave great encouragement to the American aerospace industry, and the Soviet Union also lost in the space race, ranking behind the United States.
Of course, the lunar mission is not just a space "trip" so simple. First in the United States, the national income generated by the moon landing program has doubled in ten years, and the employment indicator has created a staggering 800,000.
The technology brought by this moon landing project has also precipitated downward into the civilian use, and the artificial intelligence, remote control operations, and robots of the moon landing plan have been transferred to a larger market, and put into the industry has greatly enhanced the industrial science and technology power of the United States.
In addition, a large number of subsidiary biological, materials, and computer industries have also been driven by the aerospace project, and the development achievements of the United States in the following decades have been attributed to the Apollo Project to some extent. Barcodes like the well-known ones are also the result of this lunar exploration project, and it was originally invented to control many components of the statistical spacecraft, in addition to food dehydration technology, air cushion shoes and so on.
The lunar landing is naturally inseparable from the recording of lunar samples, and after the successful landing, the astronauts collected the rock and soil of the moon. It is reported that the collection area is also equipped with laser rangefinders, cosmic ray detectors, lunar seismometers and other high-tech equipment to analyze the moon in as much detail as possible.
Of course, the most critical achievement of the lunar landing program is that human beings have discovered an important element needed for nuclear energy on the moon - helium 3, which has made the moon have great exploration value.
The success of the US lunar mission has brought great national self-confidence to the American people, and the astronauts have been received by the president after their successful return, and the world's major radio stations have also rushed to report on it, which is undoubtedly a great feat in human history.
To this day, manned moon landings have only been successfully completed by the United States, and for various reasons, manned moon landings have rarely become the top priority of various countries in the future.
<h1 class="pgc-h-arrow-right" > voice of doubt </h1>
It is worth mentioning that while the success of the United States in the manned moon landing program has received great repercussions, it has also suffered from voices of doubt from all walks of life, and even some people say that the entire manned moon landing program is a scam, in order to trick the Soviet Union into investing more national strength in the space race or that this is just a political show, used to deceive the American people to obtain votes.
In order to list the false information in the moon landing plan, many people have even written relevant papers, hoping to prove and discuss through various examples to make the world believe that the moon landing is just an American conspiracy, a political trick.
In many later novels and films, there are also some references to the conspiracy theory of the moon landing, and the conspiracy theory is followed by a large number of fans, and the US government is also hurt by such frequent remarks.
As Apollo became a conspiracy theory amid growing skepticism, the government later released precious documentary footage. But those who believe the plan was fraudulent point out that the entire moon landing was done in the studio. Through the video at the time, it was pointed out that the American flag planted on the moon should not "flutter" at all, because the moon has no air.
Moreover, if you fast-fire the videotape at 2.25 times the speed, you will find that the astronauts behave and act the same as on Earth. You know, the gravitational pull of the moon is much smaller than that of the earth, so the astronaut jumping altitude is too low has become an argument to be questioned.
In fact, similar doubts have been published throughout the lunar mission, and these doubts seem to be justified. Since then, the United States has not put manned moon landings on space exploration, which has also made many skeptics and conspiracy theorists believe in the moon landing scam.
<h1 class="pgc-h-arrow-right" > Chang'e, China </h1>
Decades have passed, and China has also ushered in the progress of productive forces and the improvement of economic level after the reform and opening up, and has become more and more influential in the world. The success of Dongfanghong-1 has also laid a solid foundation for China's aerospace industry, and Chinese its own space program is also quietly unfolding.
In order to better study the moon, China's National Space Administration organized a large-scale aerospace project called the "Chang'e Project", which mainly carried out a series of investigations to the moon in the construction of more than ten years.
The first is lunar exploration, the basic observation and mapping of the moon; then there is the unmanned lunar landing, further field investigation of the moon to make final preparations for the third step of manned lunar landing, and China also hopes to have more understanding of the moon in the future.
With the launch of the Long March 5, Chang'e 5 successfully entered the predetermined orbit and completed the gradual correction into the orbit around the moon. Subsequently, it successfully landed on the moon, and completed the drilling of the moon, collected soil samples, and finally successfully returned to Earth with the mission.
<h1 class= "pgc-h-arrow-right" > the results of Chang'e 5 </h1>
Unlike the previous manned lunar landings in the United States, Chang'e 5's entire work was carried out mechanically, and it was also the world's first unmanned lunar landing, and the lunar terrain was mapped. Although the United States had given China a gram of lunar soil before chang'e-5 landed on the moon, it was still a little different from actually exposing it to lunar material with a clear origin.
Because of the observation of lunar soil, we found some problems that had not been considered before, that is, the color change of the lunar soil is very fast. Scientists speculate that this is due to the fact that the moon has no air, and the elements in the lunar soil do not have an oxidation reaction, and when they reach the earth, they quickly oxidize, resulting in discoloration.
The biggest significance of the Chang'e-5 mission is to be able to fully understand the formation process of the moon and the entire geographical features. Another difference from the Apollo mission is that Chang'e 5 made observations of the far side of the moon as it orbited the moon, and the landing site was also on the far side of the moon.
Thanks to the communication network planned for the first step in lunar orbit, Chang'e-5 can also receive signals on the far side of the moon to complete its work.
Much of our previous understanding of the Moon came from its frontal mid- and low-latitude lunar sea regions, and speculations about its age were also anchored by historical events in this range, which means that our understanding of the Moon in time and space is not comprehensive enough. So Chang'e-5 fills the gap in this information.
The landing area of Chang'e 5 is far from the Apollo landing site, along the Lümke Mountains, where more volcanic activity remains and more diverse samples can be collected. Moreover, in addition to the large and small craters on the far side of the moon, scientists also speculate that there should be a large amount of metal ore on the back side.
Suddenly, China has also generously shared the achievements of Chang'e-5 with the world, hoping to cooperate with more countries to build the space industry in the future, and has also gained a lot of reputation in the world.
<h1 class="pgc-h-arrow-right" > true and false </h1>
Here back to the United States moon landing scam, the Conspiracy Theory of the American manned moon landing has aroused strong opposition from many astronomical enthusiasts and researchers while the subsequent frenzied spread.
Many people are convinced of conspiracy theories because of the fluttering of the American flag on the moon. But in fact, in the strict sense, the flag is not fluttering, but shaking.
The temperature on the lunar ground is very low, and the American flag is only sewn from simple nylon cloth, which will harden directly at low temperatures. Because there is not much resistance, when the astronauts plant the national flag, the kinetic energy transmitted is transmitted within the flag for a long time, creating the illusion that the flag "flutters".
As for the astronauts' doubts about their actions, in order to ensure the safety of the astronauts at that time, the spacesuits for the moon landing were very well designed but redundant and heavy, in addition to various communication instruments and equipment, there were spare gas cylinders.
The spacesuit made by the combination of multi-layer fabric weaving is particularly heavy, and the appearance has a special coating to resist various radiation hazards, including the helmet is also treated with eye protection to prevent sunburn on the eyes. Therefore, the weight of the props worn by the astronauts themselves makes it impossible for them to reach the height of normal jumps.
But even this does not dispel the voice of doubt, and conspiracy theorists are still convinced of the moon landing fraud.
And now, with the success of Chang'e 5, the voices about the Apollo moon landing can be completely calmed.
The first is to prove the authenticity of the soil samples brought back from the moon. According to the test, we found that the basic composition of the lunar soil retrieved by Chang'e 5 is not much different from the soil sent by the United States, but because the collection location is near the crater, the soil samples in China have more rare earth elements.
Secondly, before Chang'e 5 landed on the moon, Chang'e-2 had already taken a circumnavigation of the entire moon, including the Apollo landing site.
In chang'e's scan of the entire moon, the geographical data of the moon is also consistent with the previous United States, the Soviet Union and other countries.
If all the research data is fake, then why should the United States go to great lengths to launch probes? Is it just to satisfy the ideas of conspiracy theorists? As the soviet union's greatest rival, the success of the manned moon landing program by the United States will certainly not let go of this opportunity if it can strike from all sides.
For conspiracy theorists, they tend to ignore the unintended consequences of political and social behavior, believing that all outcomes are deliberately done.
Perhaps because the manned moon landing in the United States was too successful, so that many people felt powerless, in order to eliminate this feeling of being beyond their control and seeking a reasonable explanation, this small group of people chose to believe conspiracy theories to prove themselves right.
< h1 class="pgc-h-arrow-right" > concluding remarks </h1>
Whether it is the Apollo manned moon landing program or China's Chang'e project, the success of these feats proves that human beings are full of infinite possibilities in the future.
As the united states that was the proudest in the last century, its outstanding performance in the field of space has really set an excellent example for countries that want to develop in the aerospace industry later.
Scientific research investigation and scientific research are serious, and scientific achievements have also been continuously verified through theory and practical operation through hardships and hardships. It is ridiculous to deny an achievement based on only a paranoid idea or a suspicion that does not stand up to scrutiny, and to understand the truth behind the event with the spirit of learning is the greatest respect for the spirit of science.
