Chapter 1532 Crater Mountain

In this way, Zhao Zhongyao came out of the house with his wife and children. Then came the company headquarters. Zhao Zhongyao was driving a flying saucer spacecraft. They took this UFO spacecraft together and flew to Moon City again.

After arriving in Moon City, Zhao Zhongyao first brought his wife and children to Cheng Yu's office. After all, Zhao Zhongyao came to Moon City to do things, so of course he had to discuss it with Cheng Yu. After all, the two of them are the main leaders of the 'Fei Tian Group'.

When Cheng Yu saw that Zhao Zhongyao's family had come, he was still a little puzzled. After all, he didn't know what happened to Zhao Zhongyao when he brought his wife and children to Moon City.

'Mr. Zhao, are you here for a tour? 'Cheng Yu thought, since Zhao Zhongyao came to Moon City with his wife and children, he must be here for tourism.

'Yes, we are here to travel. Only this time, instead of traveling in Moon City, we will travel to other places on the moon. Zhao Zhongyao looked at Cheng Yu and said.

‘Mr. Zhao, don’t you guys want to travel to the solar system! Why do you say you want to travel to our moon again? Have you changed your travel plans? When Cheng Yu heard what Zhao Zhongyao said, he didn't understand.

‘Haha, that’s right, don’t we have to wait for a while before we can travel to the solar system! Now our family is fine, we want to travel to the moon first. Of course, we are not pure tourism. We want to find a tourist route on the moon first. In this way, tourists who come to our moon city can not only travel in the moon 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 the earth. But there are naturally unique features on the moon. We are developing a tourist route to the moon, which will also allow us to increase our income.

Originally, our trip to the space system included a trip to the moon. Although we built a moon city on the moon, haven't we explored the whole moon yet?

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 our Moon City tourism income have another channel. And this channel can be realized very quickly. Zhao Zhongyao looked at Cheng Yu and said these things.

When Cheng Yu heard it, he felt very reasonable. After all, the moon is by their side, but they haven't seriously investigated this planet yet. Now it is necessary to take a good look at the whole moon, and then design a new tourist route.

'Mr. Zhao, what you said makes sense. Although our moon is barren. There are no conditions for life to survive. But our moon still has a lot of tourism value that can be developed. Tourism has never had to be in a place with green mountains and green waters to have tourism 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 to investigate first. Hurry up and choose the people who will travel and explore the solar system with us, as well as some equipment and supplies. In this way, when we design the tourist routes on the moon. You have also prepared your personnel, equipment and supplies. In this way, when the time comes, 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 travel and explore other places on the moon. I will select some outstanding young scientific researchers and let them travel and explore the solar system with you. Cheng Yu said the same after hearing what Zhao Zhongyao said.

'Okay, let's go to other places on the moon first. After Zhao Zhongyao finished speaking, he came out of Cheng Yu's office with his wife and children. Then he took a flying saucer spacecraft, came out of the moon city, and flew towards the moon in one direction.

Zhao Zhongyao flew in one direction of the moon while driving the UFO spacecraft. At this moment, Feifei asked Dad, ‘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 indeed no scenic spots on the moon. If anything, there are only craters and tall mountains. Although there are no green mountains and green waters on the moon, there are also many mountains. We can look for some special craters and some tall mountains. See if there is any value in developing tourist areas. If there is, we can write it down. '

'Dad, what you said makes sense, then let's go find some big mountains now! ’ Feifei said again.

Qu Yuqian and Tiantian were just looking at the environment outside the moon, and neither of them talked to Zhao Zhongyao Feifei. It's just that Zhao Zhongyao took them anywhere.

'Okay, let's go find the mountains on the moon! After Zhao Zhongyao finished speaking, he drove the flying saucer and flew into the distance again.

While driving the spaceship to the distance, Zhao Zhongyao told Feifei some knowledge about some mountains on the moon.

The Moon Mountains are also called "Moon Mountains". They are continuous mountain peaks distributed on the surface of the Moon, and they are very steep. These mountains are often named after the Earth's mountains, and their terrain 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 mare, and the most famous Apennines are located in the center of the moon. a lot of gundam

Five peaks of more than 5,000 meters.

The highest peak of the moon is located near the south pole of the moon. It is the main peak of a mountain range called Leibniz. The highest peak reaches 9,000 meters. Even the highest peak on our earth, Mount Everest (8844.43 meters), is more than 150 meters lower than it. The moon is much smaller than the earth, only 1/49 of the earth's volume, 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 activity caused by the lava flow 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 activity on the moon that can affect the lunar crust has stopped more than 3 billion years ago, so the 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 the impact of smaller mass celestial bodies, but mountains may be formed by the impact of larger mass celestial bodies.

When some asteroids or comets with larger mass hit the surface of the moon at a higher speed, the huge impact force can cause displacement and uplift of the moon's crust, which can lead to the formation of the moon's surface in a short period of time. The mountain ranges on Earth are comparable to the tall peaks. This process of orogeny usually only takes a few minutes, and the short time even does not exceed one minute, while the mountains on our earth usually take tens of thousands or even tens of millions of years. time to form. ’ Zhao Zhongyao told Feifei about some mountains on the moon while driving the flying saucer spacecraft.

After hearing this, Feifei became even more interested in these tall mountains, and wanted to hurry up to see them.

It's just that 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 also countless very small craters. It can be said that the entire moon is like a planet with pits and holes, it is not at all a bright and smooth beautiful planet that we see on the earth.

‘Dad, can you tell me some more about the craters on the moon. Are there many famous craters on the moon? Feifei looked at Zhao Zhongyao again and asked.

After hearing Feifei's words, Zhao Zhongyao smiled and said, 'Okay, let me tell you some more about the more famous craters on the moon! '

After finishing speaking, Zhao Zhongyao began to tell Feifei some of the more famous craters on the moon.

‘Let’s talk about a more famous crater first! This crater is the Kepler crater. After Zhao Zhongyao finished speaking, he thought about it for a while and told Feifei something about this crater.

Kepler crater is a large impact crater located on the front of the moon between the Ocean of Storms and the Sea of ​​Islands. It was formed about 1.1 billion years ago in the Copernican period. Its name is taken from a German mathematician, astronomer, optician and astronomer. Johannes Kepler, discoverer of Kepler's laws, officially accepted by the International Astronomical Union in 1935 The crater is adjacent to the Marius crater to the northwest and the smaller Bessarion crater to the north, Milic The Ouse crater is located in its east-northeast, south-southeast and southwest, respectively, with the Encke crater and the Mesterling crater.

The lunar surface at the center of the crater has a diameter of 29.49 kilometers and a depth of about 1.999 kilometers. Like Copernicus and Tycho, Kepler Crater has a prominent ray system, making it clearly visible even with small telescopes. The ray system extends more than 300 kilometers in all directions and overlaps with the ray lines of other craters. The surrounding terrain of the crater reaches a Schroeder brightness scale of 5°, while the crater itself is as bright as 7°.

The outline of the Kepler crater is slightly polygonal, and it has hardly been eroded by impact. There is a circle of small barriers made of ejecta on the outer edge of the towering crater, while the inner wall shows a terraced structure formed by collapse. The crater wall is 910 meters higher than the surrounding terrain on average, and the slope of the inner wall on the west side reaches 42°. There is a wall top on this side crater wall that is as high as 3,000 meters. The inner volume of the crater is about 590.92 cubic kilometers. There is a small central peak about 200 meters high.

Some ray beams from Tycho crater crossed the surface of the Oceanus tempestus to intersect the Kepler crater, which Giovanni Battista Riccioli identified in his system of lunar names An important factor in the name. Because Kepler used Tycho Brahe's observations when developing his three laws of planetary motion. On Riccioli's lunar map, the crater has been named Kepler and is surrounded by a patch of high-albedo formation called the Wind Islands. Kepler Crater is listed by the Society for Lunar and Planetary Observations on the List of Craters with Bright Ribbed Systems and the List of Craters with Dark Ribbed Sidewalls.

While driving the UFO spacecraft, Zhao Zhongyao told Feifei about this Kepler crater.

Feifei is very curious about this kind of craters, and wants to hear more about these craters. So he looked at Dad 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 again, ‘Okay, then let me tell you about a famous crater! After finishing speaking, 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 very prominent impact crater located in the highlands of the southern hemisphere of the moon. It is named after the Danish astronomer Tycho Brahe; to the south is a series of pits composed of pit streets, and to the northeast is the surrounding area of ​​Tycho Crater The surface is covered with pits of various sizes, and there are many overlapping old pits

There are some smaller craters formed by the re-sputtering of larger ejecta from Tycho crater.

Tycho Crater is a relatively young impact crater, estimated at 108 million years old based on analysis of samples from the Apollo 17 mission that re-covered the crater's radiation pattern. Such ages suggest that the impact may have been caused by a Baptistina asteroid, but the composition of the impact is still unknown, so this is only speculation at this time. However, simulated studies give Tycho a 70% chance of being formed by the impact of one of the fragments of asteroid 298.

A larger fragment from the same family may have been responsible for slamming the Chicxulub crater on Earth 65 million years ago, killing the dinosaurs. The crater has sharp edges and is not eroded by later impacts like older craters. When the sun is above it, it highlights the high albedo of its interior, and the unique radiation lines that form radiation around the crater, extending up to 1500 kilometers in length. These radiance streaks are visible even in light from only the Earth (sunlight reflected from the Earth). ’ Zhao Zhongyao told Feifei about this Tycho crater while driving the UFO spacecraft.

After hearing what Zhao Zhongyao said about these two famous lunar craters, Feifei wanted to go and see them. He really wanted to see what these two famous craters looked like.
