Chapter 1502: Aitken Basin

Chapter 1537 Aitken Basin
Of course, the reason why we think so is mainly because we are a super huge Venus spacecraft. We have this super huge Venus spacecraft. Even transporting water from the earth to the moon is relatively easy.
Because of this, we decided to transport water directly from the earth instead of exploring and developing water resources on the moon.
In fact, we don't know whether there is water at the two poles of the moon. Although the probe experiment carried out, it seems that no water was found. But we still believe that there should be water at the two poles of the moon. After all, it is very cold there. If a comet swept across the moon long ago, it should have left some solid water resources on the moon.
Before, we only worked on the construction of the Moon City wholeheartedly, and we had not explored the poles of the moon. Today, since we have come to the moon to develop tourist routes, of course we must not forget the poles of the moon.
I believe that there should be some water ice on the two poles of the moon. After all, the moon has existed for billions of years. During this period, there will definitely be many comets visiting the moon, so how can they not leave some traces on the moon! ’
Zhao Zhongyao looked at the two children and talked about what he knew about the poles of the moon. After the two children listened, they became more interested in the affairs of the moon's poles.
‘Dad, let’s go to the poles of the moon and have a look! Since there is ice there, let's see what kind of ice it is. Feifei looked at Zhao Zhongyao again and said.
'Yes! Dad, let's hurry up and take a look at the two poles of the moon! I also want to know what the two poles of the moon look like, and will I see some big icebergs? It’s the same every day. Now when she heard what Zhao Zhongyao said about the poles of the moon, she was also very interested and wanted to see it.
‘Okay, let’s go and have a look! However, I can tell you that the two poles of the moon may be dark! Don’t feel that it’s too dark in there, and you don’t want to go there! Zhao Zhongyao knows that the two poles of the moon don't get much sunlight. This is mainly because the moon's rotation axis is perpendicular to its orbit. In this case, the poles of the moon will rarely receive sunlight.
Especially in the south pole of the moon, there is a huge annular crater in the Aitken Basin. This huge basin has a diameter of 2,000 kilometers and a depth of 12 kilometers. In this huge basin is a permanently dark area.
If there is ice in Antarctica, this huge basin may be a huge solid reservoir. Zhao Zhongyao looked at the two children and said.
After hearing what Zhao Zhongyao said, the two children were also very interested in this huge solid reservoir, and they wanted to go over and take a look!
‘Dad, if the big basin might be a big reservoir, why don’t we go and take a look! Feifei immediately wanted to see the big basin.
'Yes! Dad, let's go and take a look! Everyday is also a little curious.
At this moment, Zhao Zhongyao said again, ‘what are you eager for! I will explain to you first about the Antarctic basin. After letting you understand this great basin, it is not too late for us to look at it. ’
‘Okay, dad, please speak up! Feifei looked at Zhao Zhongyao happily and said.
It was the same every day, she also looked at her dad curiously, and wanted to hear stories about this Antarctic Basin.
So, Zhao Zhongyao looked at the two children again and said, ‘The Aitken Basin at the south pole of the moon, with the largest crater known to scientists, stretches 2,000 kilometers across the far side of the moon. It is the characteristics of this huge crater that make the topography of this basin particularly eye-catching. Scientific experts believe that the Aitken Basin near Antarctica was created about 4 billion years ago. And, we already know that the pole of the moon is a unique environment for a period of time.
As one of the largest impact basins currently known in the solar system, it can help us understand the process of super-large impact events in the solar system and what they will bring; the basin is 12 kilometers deep and is the deepest impact basin on the moon, which means The impact event that year may have dug up the material from the depths of the lunar crust and even the lunar mantle, and these excavated materials will be the key to our study of the internal composition of the moon; if we want to establish the moon’s 4.5 billion years of long history, Understanding one of the oldest large impact basins on the moon has become a vital link.
After observing anomalies in the south pole of the moon, scientists began to think: when the lunar gravitational drag is roughly connected to the vicinity of the Aitken Basin in Antarctica, can this anomaly be directly traced back to the crater itself? Regarding the explanation of this extra quality, there are currently two relatively reasonable explanations. The first explanation: The metal of the asteroid that formed this crater is still embedded in the moon's mantle.
Another explanation is that this area is rich in oxides, it is likely that the ancient magma ocean of the moon cooled and then solidified to form it. Then, a reality was formed: the mass anomaly is still prominent, and it seems to be located below about 300 kilometers, which also provides an interesting idea for scientists, because these facts show that the true interior of the moon, In fact, it may not be as bad as many people expected before, because if they are, then the gravity of the moon will also pull a huge patch into the center of the moon.
There are many unsolved mysteries about the early moon. To help solve these doubts, one way is to first analyze its mantle, which is the rocky area under the moon's crust, and many other unknown places. Because of the way the earth and the moon rotate, the earth can only see one side of the moon, which is called the near side by scientists.
On the relatively flat ground of the 186-kilometer crater in the Aitken Basin, Antarctica, our scientists, judging from the minerals discovered by the Mars rover, they are significantly different from the typical lunar surface materials. The researchers said that these minerals may It was excavated from the ground of the Aitken Basin in Antarctica. Analyzing the wavelength of light reflected from these minerals revealed the existence of olivine and hypopyroxene. Scientists point out that this is consistent with long-term predictions about the composition of the upper mantle of the moon, and may support the main lunar formation models and the evolution of the icy magma ocean.
The problem of abnormal mass found under the moon’s largest crater has puzzled scientists for many years. A study showed that there is a huge mass of foreign matter under the Aitken Basin in the south pole of the moon. Scientists believe that it may be an asteroid that once hit the moon. Metal material was left on the moon after the crash.
The Aitken Basin in the South Pole of the Moon is the largest crater in the solar system. It has a diameter of more than 2,200 kilometers and almost spans the two hemispheres of the moon. However, this mysterious substance is also very special. The volume is huge, equivalent to 5 times the Hawaiian island, so huge Metal materials are buried under the Aitken Basin, and the Antarctic gravity field will inevitably be disturbed. The depth of the Aitken Basin can reach several kilometers, which also means that there is a huge metal lump deep below the Aitken Basin. This picture is simply unimaginable. Even if the material is so large, we still can't see it because it is located on the back of the moon.
This research was also published in the "Geophysical Research Letters", and the name is the deep structure of the Aitken Basin in the South Pole of the Moon. In order to measure the subtle changes in gravity around the moon, the researchers analyzed gravity recovery and internal laboratory mission data, and connected these data with the terrain data of the lunar reconnaissance orbiter, so the scientists discovered the stretch below the Antarctic-Aitken Basin There is an amazing uneven distribution of mass for hundreds of miles, which is like an asteroid embedded in the moon’s lunar mantle.
Computer simulations show that this asteroid may have an iron-nickel core. At a position more than 1 kilometer below the Aitken Basin in Antarctica, the material has penetrated into the lunar mantle several kilometers. Although we do not know the source of this asteroid, it is certain that its mass is huge, and the core material of the asteroid that caused the impact has been distributed in the lunar mantle, but it will not sink into the lunar core. . Another explanation is that the massive metals below the Aitken Basin in Antarctica may be dense oxides gathered together, and then gradually solidified over billions of years of history, and their formation is related to the lunar magma ocean.
We know that the Antarctic Aitken Basin was formed about 4 billion years ago. It is the largest crater preserved in the solar system. Although there may have been larger craters in the solar system, they have almost disappeared. Therefore, studying the Antarctic-Aitken Basin is a long-term task for scientists. We can study the impact of catastrophic impact events based on observations in the Antarctic-Aitken Basin. ’
Feifei and Tiantian heard the story about this Aitken Basin told by their father, and were full of curiosity about this basin. After all, such astronomical events are rare. Is there any water in this huge Aikente Basin? And under this big basin, is there a huge iron lump? This matter made Feifei and Tiantian also very curious.
‘Dad, are we going to have a look at the Great Basin of Aiken. I really want to know if these stories you tell are true. Feifei looked at Zhao Zhongyao and said.
‘Dad, let’s go to Aitken Basin quickly! I also want to see this great basin. Said the same every day.
After hearing the words of the two children, Zhao Zhongyao said, ‘if you are willing to go, I will take you there. However, that place was completely dark. You can only look at the terrain from the searchlight of the flying saucer. Although what I said is wonderful, when you see it, it must not feel wonderful at all. Because it is impossible for you to see the whole picture. ’
‘Dad, even if that’s the case, we want to see it. Feifei looked at Zhao Zhongyao again and said. 'Yes! Dad, you take us over! Although we can't see the whole view of this large basin from outside the porthole of the flying saucer. However, can we not see the appearance of the entire Aikente Basin through the infrared camera on the flying saucer! Everyday, he thought of another good idea.
After hearing this, Feifei looked at his father and said, ‘Dad, what every day says is that we can use an infrared camera to see what the Aikent Basin looks like from high in the sky. ’
‘Okay, since this is the case, let’s go over and take a look! Zhao Zhongyao saw that the two children wanted to see the Aikente Basin, so he decided to take the two children to see it.
So, Zhao Zhongyao drove the flying saucer spacecraft and flew to the distant Antarctic region. Due to the speed of the flying saucer spacecraft, Zhao Zhongyao and the others flew for more than ten minutes before flying over the Antarctic.
Zhao Zhongyao saw that the UFO spacecraft had already flown over the Antarctic, so he let the UFO spacecraft hover in the air first. At this time, Zhao Zhongyao checked the instrument and saw that it showed that their flying altitude was 100 kilometers. At such a height, the entire lunar south pole can be seen.
It's just that the rotation axis of the moon is almost perpendicular to the orbit of the earth. That is perpendicular to the orbit of the moon. Therefore, the two poles of the moon are always in a dark night.
Although Zhao Zhongyao knew that there was a huge Aikente Basin in the south pole of the moon. But because the sun can't reach the Antarctic area of ​​the moon. This huge basin is hard to see clearly.
However, Zhao Zhongyao knew that their flying saucers had infrared cameras on them. With the help of such a high-tech equipment, you can see what the Ebette Basin looks like.
So, Zhao Zhongyao looked at the two children and said, ‘Okay, come and see the whole Aitken Basin with me! After finishing talking, Zhao Zhongyao activated the infrared camera in the flying saucer spacecraft and aimed the camera lens at the moon’s south pole.
Feifeihe and Tiantian heard his father's words, and hurriedly came to his body together. The two of them also looked at the monitor next to Dad very curiously. Because through this display, you can see the appearance of the Ebiao basin in the Antarctic region below the spacecraft.
Zhao Zhongyao slowly adjusted the focus. After that, the entire Antarctic region was shown on the monitor. At first there was a black shadow on the monitor. After a while, this black shadow became clear. The original black shadow quickly disappeared.
When the black shadow disappeared, a huge basin appeared in the Antarctic region. The entire basin presents a circular shape. Because this basin is very large, it has a diameter of 2000 kilometers and a depth of 12 kilometers. In this case, from a high altitude, it looks like someone deliberately dug a large hole in Antarctica.
