Why can't Chang 'e V find the American flag left on the moon? Is it really a scam?

Whenever China does something on the moon, netizens will question the authenticity of the US landing on the moon. The reason is that with the progress of science and technology, it is difficult to send an astronaut to the moon, let alone in the past when computers were underdeveloped.

It is also very simple to prove the authenticity of the American landing on the moon, that is, to find the national flag left by the American landing on the moon. Since it was five times, why didn't Chang 'e V find them?

Chang'e 5

The reason why Chang 'e V didn't find the flag left by the United States when it landed on the moon was because Chang 'e V had a more important task, collecting moon rocks and soil, and then packing them and bringing them back to Earth.

However, we also know that the United States and the former Soviet Union have completed the work of sampling the surface of the moon and bringing it back to Earth. Now they have brought the soil on the surface of the moon back to the earth. In order to be different from the samples they collected, Chang 'e V chose a place that humans have never explored: the near-earth position of the moon storm ocean high volcano Mount Luke. Far from the flag left by the Apollo program.

This address was chosen because the samples brought back by the United States and the former Soviet Union are very old, with a history of more than 3 billion years. However, the age of rocks where China's Chang 'e-5 probe landed will not exceed12-1300 million years, which is more valuable for scientific research.

In addition, the landing site of Chang 'e-5 probe used to be a volcano. Sampling here and bringing it back to earth will help us understand the formation and activities of lunar volcanoes and fill the gap in the history of lunar volcano research.

It is precisely because of the heavy responsibility of Chang 'e V that we have not focused on finding artifacts such as the American flag left by the Apollo program, but on exploring the moon.

Is there really an American flag on the surface of the moon?

Judging from the photos released by the United States in earlier years, the American flag planted on the moon looks like it is flying in the breeze. This has also become the biggest question of whether humans will land on the moon. The reason is that there is no wind on the surface of the moon and there is no way to blow the national flag. In that case, why can the American flag "fly in the wind" on the surface of the moon?

In this regard, Mo Ze, the engineer in charge of landing on the moon at that time, said that the national flag inserted on the surface of the moon was not just a railing, but an inverted "L" shape, which fixed it. In addition, when the national flag was unfolded, the machinery broke down, which led the astronauts to try to unfold the national flag with the tools at hand. But the fibers on the national flag are accidentally mixed together, and from the lens, it looks like a national flag flying in the wind.

Later, NASA also used the camera of the lunar reconnaissance orbiter to find the American flag. Although it is too far away to directly observe the appearance of the national flag, you can still see the shadow left by the national flag on the surface of the moon if you look closely. Except the flag left by Apollo 1 1, the other five flags are still there.

Just because the American flag left on the surface of the moon is made of nylon, scientists now analyze that the American flag left on the surface of the moon is likely to have faded and damaged.

This is because the moon has no atmosphere, which enables the sun's ultraviolet rays and other high-energy particles to directly irradiate the surface of the moon. Coupled with the large temperature difference between day and night on the surface of the moon, extreme weather will destroy the integrity of the national flag, so that some people posted a picture on the Internet to ridicule: the national flag of the United States should turn white under solar radiation, which looks like France landed on the moon that year.

The national flag carried by China Chang 'e V is a special national flag, which will not be deformed or faded for a long time.

The research team spent 1 years on the selection of materials, and finally screened out 20-30 kinds of fiber materials, and then made a new composite material through various tests, which can not only meet the requirements of long-term colorfastness, deformation and cross-color on the lunar surface, but also resist the harsh environment on the lunar surface. In addition, in order to save fuel, scientists reduced the weight of the national flag, keeping the total weight of the national flag at 1kg, which is lighter than the national flag carried by the Apollo program and can stay on the moon for a longer time.

abstract

Chang 'e V landing on the moon not only cost a lot, but also condensed the efforts of many people. It can be said that there are too many efforts. It is precisely because of the expectations and efforts of too many people that the purpose of Chang 'e V landing on the moon is not to test whether others really landed on the moon, but to do something greater: bring the lunar soil back to the earth.

Bringing the lunar soil back to the earth can provide more scientific research information for human beings, help us understand the planets outside the earth, and help us to detect other planets and even space immigrants in the future.

And if the expensive Chang 'e V is used to test whether others have successfully landed on the moon, it will not only waste huge funds in China, but also be of little help to China's scientific research, so it is impossible for us to look for the national flag left by the Apollo program.
