, NASA's Artemis 1 lunar rocket, originally scheduled to be its first flight at the end of August, encountered consecutive failures, including sensor abnormalities and fuel leakage, resulting in the rocket launch time being delayed again and again. The rocket has been waiting on the launch tower for a month and has not been launched for a long time. In addition, it may be pushed back to the rocket assembly building after catching up with the incoming Hurricane .
In recent years, Chinese probes have successively visited the moon to explore, Chang'e-1 and 2 orbit the moon, Chang'e-3 and 4 landed on the surface of the moon, and Chang'e-5 not only successfully landed on the moon, but also brought lunar samples back to Earth. The Chinese probe saw various phenomena on the moon, which made some people question the authenticity of the American Apollo landing on the moon back then.
1969, NASA's Apollo 11 flew to the moon with three astronauts. One of the astronauts was stationed in the lunar orbit, and the other two astronauts flew the lunar module and successfully landed on the front of the moon. The two of them became the first humans to step on the surface of the moon.
In the next three years, NASA launched six Apollo spacecraft . In addition to the failure of Apollo 13 to land on the moon, the other 4 spacecraft successfully landed in different areas on the front of the moon, and another 10 astronauts set foot on the moon. Every time they land on the moon, astronauts bring back dozens or hundreds of kilograms of lunar rock and lunar soil.
After my country's Chang'e 3, 4 and 5 landed on the moon, it seemed that they saw different scenes on the moon. Chang'e-3 landed on the front of the moon, and the Yutu lunar rover was also landing on the moon. Chang'e-4 landed on the back of the moon (the first time in human history), and Yutu-2 also sailed on the back of the moon.
Whether it is Yutu or Yutu 2, both lunar rover weighing about 140 kg left very obvious ruts when driving on the lunar table. The moon surface is covered with lunar soil, and as long as you drive on it, there will be obvious traces.
. Some netizens discovered that when browsing Apollo's moon landing photos, the Apollo lunar rover was driving on the moon surface and did not seem to leave any ruts. Although there are many footprints on the moon surface, there are no traces of the lunar rover passing by, which is a sharp contrast with the lunar rover in our country.
In the Apollo 15 mission, the Apollo lunar rover was taken to the moon for the first time, and there were also lunar rovers on Apollo 16 and 17 after that. This rover can ride two astronauts, expand the range of movement of the astronauts and bring back more lunar samples.
Apollo lunar rover weighs about 210 kg, which is 70 kg heavier than the Jade Rabbit lunar rover. In addition, the two astronauts in space suits weigh at least dozens of kilograms themselves. Such a heavy lunar rover should leave deep ruts when driving on the moon, but why didn't they see it in the photos?
This is actually because the photo shows the direction of the lunar rover, and the photo is cropped and the situation behind the moon cannot be seen. In fact, the complete photo of the lunar rover looks like this:
You can see that there are obvious ruts behind the moon. Since there is no wind and rain on the moon, the traces left by the moon landing that year are still retained on the moon. Through the high-resolution lunar table photos sent back by NASA lunar survey orbiter (LRO), you can see that the ruts left by the Apollo lunar rover are still on the lunar table:
In addition, we can also see the ruts left by the Jade Rabbit lunar rover on the lunar table. Since my country's Yutu 2 is still driving on the back of the moon, the ruts it leaves on the lunar surface will become longer and longer.
When Chang'e-3 and 4 landed on the moon, there was a five-star red flag on the lander and the lunar rover, but the national flag was sprayed on the probe and was not a real flag. When Chang'e-5 landed on the moon, he brought the first "fabric version" five-star red flag and successfully displayed it on the moon.
Judging from the images sent back by the Chang'e-5 lander, our country's national flag looks very flat.During the Apollo moon landing, astronauts planted a flag on the moon every time, and the American flag looked wrinkled and seemed to be fluttering in the wind, which was very different from the Chinese flag, which made some people question whether the United States had actually landed on the moon.
The moon's surface is a vacuum environment and does not have an atmosphere, so there will be no wind. Since there is no wind, it is impossible for the flag to float on the moon. The American flag looks fluttering not because of fraud, but because of other reasons.
One is made of American flag, which is made of ordinary nylon, and when taken to the moon, it is simply folded, so when the flag is unfolded on the moon, it looks like there are many wrinkles. On the other hand, there is a transverse support pole on the flag, which keeps the flag spread open. Astronauts shake the flag when installing the flag, and on the moon without air resistance, the flag will shake for a long time.
In order to make the five-star red flag better spread on the moon, my country has selected aramid fiber. It has excellent performance and high strength. It can adapt to the harsh lunar surface environment and will not fade for a long time. Moreover, there are support at four corners of the Chang'e-5 flag to minimize folds. Not only that, our country's national flag is also packaged and unfolded in the form of a scroll, thus keeping the national flag flatter.
my country's exploration of the moon continues, and more five-star red flags will reach the surface of the moon with the Chang'e probe. In the near future, when our astronaut also lands on the moon, he will personally erect a bright five-star red flag on the moon.
