"We successfully landed on the moon and planted a five-star red flag on the moon."
In the documentary "Chinese's Space Dream" broadcast by CCTV in 1981, mainland astronauts and Chinese people issued a call for praise.
It was July 1981, at the beginning of the mainland's economic opening up in the 80s of the last century, people were vying for all kinds of new things, and the vigorous moon landing program also became a space journey in people's dreams.
The moon landing has always been the most mysterious event, 2.5 billion years ago, both the Earth and the Moon experienced several large-scale impacts, this powerful impact caused the moon to break away from the surface of the earth, and then quietly moved forward with the earth, for 2.5 billion years, the moon has been quietly around people's nights.
In 1969, the American "Apollo 11" spacecraft was successfully launched, and everyone was full of expectations for this space exploration, but after the moon landing, people found that the moon landing tape was different from the usual shooting, and the crescent moon was seen in a place where there were no stars at all.
1. Problems with the moon landing.
Many people believe that the US moon landing is fake, and the Americans deliberately filmed on the moon without stars in the video they shot in space, and planted an American flag at the moon landing site to make the world believe that the United States landed on the moon.
Since then, the United States has gradually become silent in the field of space, and later some countries planned to explore the lunar landing site, but found that many instruments on the lunar landing site were unfortunately missing.
This also calls into question the authenticity of the moon landing.
If the Americans have never been to the moon, then why did they plant the American flag at the moon landing site?
How can the flag still fly?
According to the direction of the wind on Earth, can the wind blow to the moon?
Some people even pointed out that the shape of the American flag flying did not match the direction of gravity, believing that this was the reason why the moon landing was fake.
So why did the United States plant the American flag at the moon landing site, and why did the national flag fly?
2. The reason why the American flag is flying.
On July 16, 1969, the Apollo 11 spacecraft lifted off from the Kennedy Space Center in Florida with three astronauts, Aldrin, Armstrong and Colin.
Five days later, all three landed safely in the vast expanse of the Pacific Ocean.
The Apollo mission was a great feat of landing a man on the moon, and Armstrong and Neil Aldrin stepped out of the lunar module after landing on the surface of the moon after the Apollo 11 lunar module landed on the lunar surface, planting the American flag on the moon, making the United States the first country to successfully land on the moon.
So why is the American flag flying?
Some people think that Armstrong deliberately shook the flag when planting it, while others think that the flag's pole is too soft, so that the wind or the wall can shake the flag.
In fact, the reason why the American flag flies is very simple, because there is no air blocking on the moon, so it is impossible for the wind to blow, and when the orbital module and the propulsion module of the lunar module separate, there will be some rotation, so in the process, the American flag will be blown up in the high-speed air flow ejected from the propulsion module.
In addition, the design of the flag support pole is made of lightweight materials, which can make the flag swing even by its own gravity.
The explanation for why there are no stars in the photos of the moon landing is also very simple.
Since the surface of the moon is very sunny, some people have done experiments that they will not be able to photograph stars when they take pictures in the sun, but the stars are not visible in the photos.
In addition, photographing in very complex conditions during the moon landing, brightly colored stars are likely to be obscured by dust on the surface of the moon.
3. Why the United States is withdrawing from space exploration.
In 1982, U.S. Secretary of Commerce Bowman Brown announced that the U.S. would carry out mass layoffs in space exploration, laying off 60 percent of its workforce and shutting down costly space flight programs.
So why has the United States entered a period of silence in space exploration?
In fact, a few months ago, US President Ronald Reagan also announced the end of the "Apollo" series of missions, and it was passed by the US Congress.
Since then, the United States has gradually withdrawn from space exploration, instead investing most of its energy in the Space Shuttle.
So why is the United States gradually abandoning research in the field of space exploration?
After the end of the Apollo mission, the United States planned to explore 14 Apollo missions before 1970, but the United States did not have a lunar mission after the end of "Apollo 17" in 1972, and has not proposed a plan to return to the moon until today.
After the end of the "Apollo" series of missions, the United States only had the "Space Shuttle" able to enter space, but the Space Shuttle could not enter the lunar surface, so under these conditions, the United States did not carry out any more missions to the moon at all, and the United States has no plan to return to the moon until today.
Not only that, after the completion of China's manned space mission, Tiangong-1, Tiangong-2, and Tiangong-2 have all been completed, and with the addition of manned spacecraft such as probes and satellites, it can be said that the United States' ability in the field of space exploration has been surpassed by China by relying only on the "space shuttle."
The progress of the United States in the field of space exploration has been slow, so what is it that makes the United States so difficult, or even slow?
Mainly because the United States is facing an economic crisis after the moon landing, the depreciation of the dollar, and the gradual decline of domestic economic efficiency, under such circumstances, the United States has to drastically reduce its investment in space exploration, resulting in the stagnation of space exploration research.
Because the depreciation of the US dollar also affects the people's livelihood in the United States, the US government has to apply to Congress for more funds to improve the people's livelihood and adjust the national economic policy.
Fourth, the future of space exploration.
In any case, after the moon landing, human beings have more yearning for space exploration, and since then people have begun to pay more attention to the issue of "moon landing", and space exploration has also become a hot topic.
As far as China is concerned, the mainland's exploration of the field of space exploration is not superficial, since the successful launch of Chang'e-1, the pace of the mainland's space exploration has not stopped, and after the successful launch of Chang'e-2 and the successful soft landing of Chang'e-3 and a series of successful exploration missions, the mainland's space exploration has just begun.
The process of human exploration of space is only a few decades, and the earth is divided into many countries and regions, different countries in the field of space exploration research degree is not the same, many countries are through space exploration to show their strength and image, to a large extent, space exploration has not only represented the development of technology, but also the dignity and glory of a country, it is a part of human civilization.
Globally, countries such as the United States, Russia, China, Europe and India are actively developing space exploration capabilities, and the global space race is becoming more and more intense, not only in terms of technology, but also in many countries planning to explore the moon landing site in order to rule out the hypothesis of the moon landing.
Of course, space exploration is not just a national act, international cooperation and private business play a very important role in space exploration.
This is due to the enormous challenges faced by scientists and engineers in the exploration of space, not only technical problems, but also energy, resources and security issues, which require people to work together to overcome these problems through technology and intelligence.
In the future exploration process, it can be said that mankind will benefit a lot, more innovative products and technologies will be produced, more scientific theories will be verified, more secrets of the universe will be revealed, and more data will be collected.
However, in the process of space exploration, human beings will also face a variety of difficulties and problems, but this will not affect people's enthusiasm and yearning for space exploration, people will continue to pursue and expect, and at the same time, more resources and funds are needed to support people to continue to study space.
epilogue
In any case, the outstanding achievements of mankind in the field of space exploration have brought more beauty to people's lives, and at the same time, they have also uncovered one unknown territory after another in the universe for the benefit of mankind.
In the future, mankind will continue to explore more unknown areas and open a new chapter in space exploration.
