Chapter 1497: Crater
The first thousand five hundred and thirty-two chapters
In this way, Zhao Zhongyao took his wife and children out of the house. Then came to the company headquarters. Zhao Zhongyao drives a flying saucer spacecraft. They took the flying saucer spacecraft together and flew to Lunar City again.
After arriving at the Moon City, Zhao Zhongyao first took his wife and children to Cheng Yu's office. After all, when Zhao Zhongyao came to the Moon City to do things, of course he had to discuss it with Cheng Yu. After all, the two of them are the main leaders of the Feitian Group.
Cheng Yu saw that Zhao Zhongyao's family had arrived, and he was still a little puzzled. After all, he didn't know what happened to Zhao Zhongyao bringing his wife and children to the Moon City.
‘Mr. Zhao, are you here to travel! Cheng Yu thought, since Zhao Zhongyao brought his wife and children to the moon city, he must have come to travel.
‘Yes, we are here to travel. Only this time, we are not traveling in Lunar City, but traveling to other places on the moon. Zhao Zhongyao looked at Cheng Yu and said.
‘Mr. Zhao, aren’t you going to travel to the solar system! Why do you want to travel to our moon again? Did you change your travel plan? When Cheng Yu heard Zhao Zhongyao say this, he didn't understand.
‘Haha, that’s right, don’t we have to wait a while before we travel to the solar system! Now our family is fine, we want to travel to the moon first. Of course, we are not purely traveling. We want to find a tourist route on the moon first. In this way, visitors to our lunar city can not only travel in the lunar city, but also travel to other places on the moon.
Although there is no air or water on the moon. There are no green mountains and green waters on earth. But there are naturally unique features on the moon. We are developing a lunar tourism route, which can also increase our income.
Originally, our travel expedition to the space department included a travel expedition to the moon. Although we have built a lunar city on the moon, haven't we yet conducted a tourism exploration of the entire moon!
Now our family will travel on the moon first. Find some resources with tourism value, and then you can develop a tourist route outside the moon city. Let us have another channel for our lunar city tourism revenue. And this channel can be realized quickly. Zhao Zhongyao looked at Cheng Yu and said these things.
Cheng Yu felt very reasonable when he heard it. After all, the moon is by their side, and they have not seriously investigated this planet. Now it is necessary to take a good look at the entire moon and then design a new tourist route.
‘Mr. Zhao, what you said makes sense. Although our moon is deserted. There are no conditions for life to survive. But our moon still has a lot of tourism value that can be developed. Traveling never has to be in the green mountains and rivers to have tourist value. As long as it is a very special place, it can be developed into a tourist area. Just like some deserts on the earth, it can become a tourist attraction. Although there are no signs of life on the moon, some tourist attractions with tourist value can still be developed. Cheng Yu looked at Zhao Zhongyao again and said.
‘Okay, that’s it, let’s go to the moon first. You can quickly select the personnel and some equipment and supplies to travel and explore the solar system with us. In this way, when we design the tourist routes on the moon. You have also prepared personnel equipment and materials. In this way, we can travel and explore the solar system together. Zhao Zhongyao looked at Cheng Yu again and said.
‘Okay, let’s work together! You can go to other places on the moon to travel and explore. I will select some outstanding young scientific researchers and let them travel and explore the solar system with you. After hearing what Zhao Zhongyao said, Cheng Yu said so.
‘Okay, let’s go and see other places on the moon first. After finishing talking, Zhao Zhongyao came out of Cheng Yu's office with his wife and children. Then took another flying saucer spacecraft, came out of the moon city, and flew in one direction of the moon.
Zhao Zhongyao flew in one direction of the moon while driving the UFO spacecraft. Feifei asked Dad at this time, ‘dad, where are we going to fly now, where are we going to travel on the moon. ’
After hearing what his son said, Zhao Zhongyao said, ‘There are really no scenic spots on the moon. If anything, there are only craters and tall mountains. Although there are no green mountains and green water on the moon, there are still many mountains. We can look for some special craters and some tall mountains. See if there is any value in developing tourist areas. If so, we can write it down. ’
‘Dad, what you said makes sense, then let’s go find some mountains now! Feifei said again.
Qu Yuqian and Tiantian were just looking at the environment outside the moon, and neither of them spoke to Zhao Zhongyao Feifei. It's just that Zhao Zhongyao takes them anywhere.
‘Okay, let’s find the mountains on the moon! After Zhao Zhongyao finished speaking, he flew away again in the flying saucer spacecraft.
As Zhao Zhongyao flew the spacecraft far away, he taught Feifei some knowledge about the mountains on the moon.
'The lunar mountain range is also called the "lunar mountain system", which is represented by the continuous distribution of mountain peaks on the surface of the moon, and it is very steep. These mountains are often named after the earth's mountain ranges, and their topography is similar to that of the earth's mountains. There is no ecological environment such as vegetation. They are usually 2 to 3 kilometers higher than the lunar sea. The most famous Apennine mountain range is located in the center of the moon. It is the longest mountain range on the moon, about 1,000 kilometers long, most of which are 3 to 4 kilometers higher than the lunar sea. Many peaks are more than 55,000 meters high.
The highest peak of the moon is located near the south pole of the moon. It is the main peak of a mountain called Leibniz. The highest peak reaches 9,000 meters. Even the highest peak of our planet, Mount Everest (8844.43 meters), is more than 150 meters lower than it. The moon is much smaller than the earth, only 149 the size of the earth, but the highest mountain on the moon is higher than the earth, which is really unexpected.
We all know that the mountains on the earth are caused by plate activities caused by the activity of lava flows under the crust. So how did the mountains on the moon form?
In fact, the reason for its formation is completely different from that on the earth. It is generally believed that the lava activities on the moon that can affect the lunar crust ceased more than 3 billion years ago. Therefore, the high mountains on the moon cannot be derived from lava activities. It is believed that they are formed by the impact of celestial bodies in the same way as the lunar craters. Relatively speaking, craters are easily formed by impacts of smaller-mass celestial bodies, but mountains may be formed by impacts of larger-mass celestial bodies.
When some large-mass asteroids or comets hit the surface of the moon at a high speed, the huge impact force can cause the moon's crust to shift and uplift, which can cause the formation of the moon's surface and the earth in a short time. The mountain ranges are as tall as the tall peaks. This orogenic process usually only takes a few minutes, and the time is less than one minute. The mountains on our planet usually take tens of thousands or even tens of millions of years. Time can be formed. While driving the flying saucer spacecraft, Zhao Zhongyao told Feifei this knowledge about the mountains on the moon.
After hearing that, Feifei became more interested in these tall mountains, and wanted to hurry up and take a look on these mountains.
Only Feifei knows that the most terrain on the moon is the crater. There are many craters on the moon. There are probably more than one million relatively large craters. There are countless very small craters. But the whole moon is like a pitted planet, not a bright and sleek beautiful planet like what we see on the earth.
‘Dad, can you tell me more about the craters on the moon. Are there many famous craters on the moon? Feifei looked at Zhao Zhongyao and asked.
After hearing what Feifei said, Zhao Zhongyao smiled and said, ‘Okay, let me tell you something about the more famous craters on the moon! ’
After finishing talking, Zhao Zhongyao began to tell Feifei some more famous craters on the moon.
‘Let’s talk about a more famous crater first! This crater is Kepler crater. After Zhao Zhongyao finished speaking, after thinking about it for a while, he told Feifei something about this crater.
Kepler crater is a large impact crater on the front of the moon between the storm ocean and the island sea. It was formed in the Copernican period about 1.1 billion years ago. Its name is taken from a German mathematician, astronomer, optician and astronomer. Johannes Kepler, the discoverer of Kepler's laws, was officially accepted by the International Astronomical Union in 1935. The crater is close to the Malius crater in the northwest and the smaller Bessarion crater to the north, Milic. Uss crater is located in the east-northeast, south-southeast and southwest of its crater Encke and Meisterlin respectively.
The center of the crater has a lunar diameter of 29.49 kilometers and a depth of 1.999 kilometers. Just like the Copernicus crater and Tycho crater, Kepler crater also has a striking beam pattern, so it can be clearly seen even with a small telescope. The firing pattern system extends to more than 300 kilometers around and overlaps with the firing patterns of other craters. The Schroth brightness level of the terrain surrounding the crater reaches 5°, and its own brightness is as high as 7°.
The Kepler crater has a slightly polygonal appearance and is hardly corroded by impact. The towering crater has a ring of small barriers made of ejected materials on the outside, and the inner wall shows a terrace-like structure formed by collapse. The crater wall is 910 meters above the surrounding terrain on average. The inner wall on the west side has a **** of 42°. On the side crater wall, there is a top of 3000 meters, the crater volume is about 590.92 cubic kilometers, and the bottom surface is rugged. There is a small central peak about 200 meters high.
Some beams from the Tycho crater cross the surface of the storm ocean and intersect with the Kepler crater, which also became Giovanni Battista Riccioli’s identification of the crater in his moon name system An important element of the name. Because Kepler used Tycho Brahe's observations when developing his three laws of planetary motion. On Riccioli's moon map, the crater is named Kepler and is surrounded by a high albedo layer called Wind Island. Kepler Crater has been included in the "List of Impact Craters with Bright Radiation System" and "List of Impact Craters with Dark Radiation Patterns on the Inner Walls" by the Lunar and Planetary Observation Association.
While driving the flying saucer spacecraft, Zhao Zhongyao told Feifei about this Kepler crater.
After flying, I am very curious about these craters, and I want to hear more about these craters. So he looked at his father and said, ‘can you tell me about another famous crater! There are not many famous craters on the moon. ’
After hearing what his son said, Zhao Zhongyao said, ‘Okay, let me tell you about a famous crater! After finishing talking, Zhao Zhongyao thought about it for a while and then started talking again.
‘I’ll tell you another crater called Tycho Crater, which is also a very famous lunar crater. Tycho crater is a prominent impact crater located in the highlands of the southern hemisphere of the moon, named after the Danish astronomer Tycho Brahe; to the south is a series of pit streets, and to the northeast is the surrounding Tycho crater The surface is covered with pits of various sizes, and there are many overlapping old pits, and some of the smaller pits are formed by the larger spray spattered from the Tycho Crater.
The Tycho crater is a relatively young crater. According to the analysis of the radiation pattern samples covered by the crater during the Apollo 17 mission, the age is estimated to be 108 million years. Such age suggests that the impact may have been caused by a Baptistina asteroid, but the composition of the impact is still unknown, so this is only current speculation. However, the simulation study concluded that there is a 70% probability that the Tycho crater was formed by the impact of one of the fragments of asteroid 298.
A larger fragment from the same family may be the culprit of the Chicxulub crater that hit the earth 65 million years ago, causing the extinction of the dinosaurs. The edge of this crater is clear, unlike those ancient craters that were eroded by subsequent impacts. When the sun is above him, it highlights the high albedo inside it, and there are unique radiating rays around the pit, extending up to 1,500 kilometers in length. These radiation patterns can be seen even when there is only light from the earth (sunlight reflected by the earth). "Zhao Zhongyao told Feifei about the Tycho crater while driving the flying saucer spacecraft.
After hearing what Zhao Zhongyao said about these two famous moon craters, Feifei wanted to see it. He wanted to see what these two famous craters looked like.
