A few centuries ago, human beings could only look up at the stars, fantasizing and wondering about the two spheres hanging in the sky to protect day and night.
With the development of human science and technology, landing on the moon seems to be no longer a distant "difficult task". However, many people, including the American people, have questioned whether the Apollo manned spacecraft in 1969 was a hoax or a fact?
The “doubtful” moon landing plan
Their doubts were not groundless. After the United States successfully landed on the moon, astronauts brought 380kg of samples collected from the moon back to Earth for study, and generously gave away more than 200 rocks.
Among them are our country and the Netherlands. The Dutch government was very happy and stored it in a museum. However, when experts from the museum studied it, they found that the rock was a fake. It was most likely a fossilized wood from Arizona . After the rumor emerged, more people questioned that the so-called samples they brought from the moon were actually fake, especially the soil. They believed that NASA deliberately used soil developed from lunar meteorites in order to confuse the fake with the real.
In addition to this doubt, enthusiastic netizens began to contribute their own findings. Some people sharply pointed out that the photos taken by the astronauts were fake scenes built with background panels.
We all know that there are countless celestial bodies in the universe, with bright galaxies, and beautiful and gorgeous colors everywhere. However, in the photos of astronauts landing on the moon, the universe is completely dark. What is going on? Are you really deceiving people?
Refuting conspiracy theories
Conspiracy theories caused by the Apollo moon landing program. Most people suspect that NASA has other plans for the funds raised. It may be used to explore more distant Mars or other planets. Therefore, many American people also doubt that they have tampered with the funds. But is this really the case?
Let’s talk about the black background plate first. The refractive index of light on the moon’s surface is 7%-10%, which is equivalent to us taking pictures with super bright fill lights on the earth. The photos taken at the same time are very clear and the light angle is particularly good.
There is currently no clear answer to the "fake rock" received by the Netherlands. Some people say that the one given to the Netherlands may be a "fake". This is because the United States at that time wanted the world to see its demeanor as a great power. Therefore, in the 1970s, the United States also sent a national security assistant to present lunar soil weighing 1 gram to China, with the purpose of promoting the establishment of diplomatic relations between the two countries.
I don’t know if I should say that the United States is more generous. In order to look “good-looking”, they deliberately placed the soil, which is only the size of a bean, in a transparent box. Under the visual effect of the box, the soil looks quite big.
However, even so, there is only 0.5 grams available for scientists to study, but even so small, it is enough to excite scientists, because this is a "native product" from the moon!
The research work mainly starts from the structure and composition of the soil, and then grinds it into powder for in-depth study. The lunar soil contains a lot of gold elements, which is relatively unique.
At that time, because China did not have enough strength to complete the moon landing mission, when we obtained this precious soil, our country's Ouyang Ziyuan led students to study it. Ouyang Ziyuan was a professional researcher in meteorites. Although it seemed inconsistent, he still completed 14 papers during the research period, which greatly amazed scientists at home and abroad.
According to research results, this soil does indeed come from the moon, and it is said to be 3.7 billion years old. According to previous analysis by scientists, about 99% of the rock composition on the moon is much older than that on the earth. Some rocks are as old as 4.5 billion years old, and the oldest rock on the earth, Acasta Gneiss, is only 4 billion years old. Of course, these data may also be exaggerated.
As for the "fake goods" received by the Netherlands, there are different opinions. Some say they were intentional by the United States, while others say they were subcontracted by internal people.
In fact, before the Apollo successfully landed on the moon, the Soviet Union had sent technical dogs into space. If it had not been deeply involved in a political crisis later, perhaps the Soviet Union would have been the first country on earth to complete a manned moon landing. Other countries have not yet developed more advanced technologies and funds, so the United States took the lead.
The authenticity of the Apollo moon landing is beyond doubt. In the following years, India's Chandrayaan 1 and my country's Chang'e 2 successively landed on the moon. They also photographed various behavioral traces left behind by the Apollo moon landing, including more powerful evidence: the first human footprints on the earth.
Although after a long period of "exposure", everyone speculated that it may have been covered, there is no wind and sand on the moon, so the footprints can exist for at least 50 years. This footprint was also included in the images returned after my country launched Chang'e 2, which fully confirmed that Apollo's moon landing plan was not false.
China's Moon Landing Plan
In January 2019, Chang'e-2 successfully launched into space under much-anticipated expectations and completed the arduous mission of landing on the moon. In 2020, 1,731 grams of lunar soil samples were collected for research. For this lunar landing, our country used an unmanned detector, which is more convenient for purposeful collection and research after manned lunar landings.
Although most people regard the moon landing plan as something they are proud of, a few people think it is a waste of money. After all, the entire project will continue to burn money.
However, the moon landing plan must be completed. Before the official launch of Chang'e 2, our country planned like this: first, we must send an unmanned probe to the moon, then manned landing on the moon, and finally and most importantly, establish a base on the moon.
Only by establishing a lunar base can we have the opportunity to better carry out astronomical observation activities. In addition, we can use lunar resources to build space power stations and refer them to the earth for use, which can better save earth resources.
So why choose the moon?
First of all, the moon is about 384,000 kilometers away from the earth. Compared with other planets, the distance is relatively close. Humans can reach it within 3 days with the current level. The short time means the reduction of time costs, which may involve fuel resources, etc.
In addition, if a human base is established on the moon, it will be most beneficial for exploring more mysteries of the universe in the future, and communication will be more convenient.
From another broader perspective, if humans will immigrate to other planets in the future, then we can use the moon as a starting point. What will happen if humans live in outer space for a period of time? As well as our need to adapt to the environment of outer space, how we should live in a low gravity environment, these all need to be studied.
Finally, why is our country so "anxious" to complete the moon landing plan? What we need to pay attention to is that resources are always the core of competition. Many countries, including Japan and India, are ready to use resources in outer space. At the same time, they have also formulated their own plans. The future direction and foothold are obvious. We need to speed up the progress to seize the opportunity.
