Chapter 1761: Searching for an Oasis of Life
After hearing what Tiantian said, Feifei smiled and said, ‘Sister, what are you talking about! Don't you worry about Dad's driving skills! ’
Hearing what my brother said every day, he smiled and said, ‘I’m not worried about Dad’s driving skills, I’m just worried that the sun’s gravitational force is too great for our spacecraft to resist. ’
Hearing what my sister said every day, she smiled and said, ‘Sister, although the sun is very big, his gravity is also very big. But the gravitational force between two objects is determined by the mass of the two objects. If the masses of two objects are very large, then the gravitational force between them is also very large. It's like gravity between planets. Because of their great mass, the gravitational force between them is also great.
But our spacecraft is too small compared to the sun. The sun’s gravitational force is great, but the gravitational force exerted on the spacecraft is very small. Even if we are very close to the sun, we don't have to worry about being sucked in by the sun. Of course, this is relatively speaking. If it is really very close to the sun, it is also possible to let the sun in.
It's like our human aircraft in space. As long as it is a few hundred kilometers away from the earth, it will be affected by a small gravitational force, and it can hardly be affected by the gravitational force of the earth. But when you are only tens of kilometers away from the earth, you will be subject to the earth's great gravity. This gravitation is not only related to the mass of the object, but also related to the distance between the objects. ’
Hearing Feifei’s words every day, he smiled and said, ‘Brother, do you feel that I have never been to school! You still show these ordinary physics knowledge in front of me. ’
Feifei smiled and said, ‘I’m not showing off, I feel that you haven’t gone to school in the past few months, as if you have forgotten these common knowledge. ’
When Feifei and Tiantian were talking like this, Zhao Zhongyao had already flown near Mercury while driving the spacecraft.
At this time, Zhao Zhongyao looked at Feifei and Tiantian and said, ‘Don’t fight between you two, our spacecraft will not attract the sun. But soon Mercury will be attracted to it. ’
‘Dad, we have arrived on Mercury so soon. ’
Feifei saw a huge planet suspended in space not far ahead. He immediately didn't want to talk about physics to Tiantian. He wanted to appreciate the Mercury in space.
‘Of course, how fast is our ship. We flew from Venus to Mercury in just over an hour. Said Zhao Zhongyao.
‘Dad, let’s fly over Mercury and have a look! I just want to see what this planet looks like. Feifei is very interested in Mercury in front of her, and wants to see what it looks like on Mercury.
‘Okay, let’s go to the front of Mercury first! With sunlight on the front, we can see exactly what the surface of Mercury looks like. Said Zhao Zhongyao.
‘Okay, let’s take a look at the front of Mercury. Feifei said so too.
Soon, Zhao Zhongyao drove the spacecraft and flew several hundred kilometers above Mercury. You can see the surface of Mercury in this place.
Zhao Zhongyao now pilots the spacecraft and begins to fly in front of Venus. Feifei, Tiantian, and Qu Yuqian were all curiously beginning to observe Mercury's surface.
‘Dad, does this Venus look like the moon! Just some craters. Apart from these craters, there is no other special terrain. Feifei looked at the surface of Mercury below, there were some impact craters, and he felt that the surface of Mercury and the moon were very similar.
‘Yes, the surface of Mercury and the Moon are very similar. However, this is only the front of Mercury. The front of Mercury is very similar to the surface of the moon. But the back of Mercury is different from the top of the moon. Said Zhao Zhongyao.
‘Why, what’s the difference. Feifei still doesn't understand.
‘North of Mercury is a dark world. Because Mercury locks the solar tide. The front of Mercury is always facing the sun. Its back is always facing the sun. What does the back of Mercury look like? No one knows yet! Said Zhao Zhongyao.
‘Dad, shall we go to the back of Mercury and see. Said Feifei.
‘Of course, we’ll wait a while and go to the back of Mercury. The front of Mercury is actually nothing good. Said Zhao Zhongyao.
After speaking, Zhao Zhongyao flew the spacecraft in front of Mercury again. Only when they reached a huge crater. Zhao Zhongyao said again, ‘this is the largest impact crater on Mercury. It is also the hottest place above Mercury. This impact crater may have been formed by an asteroid impact two billion years ago. It was the impact of this asteroid that made the crust and mantle of Mercury's surface disappear. There is only a core rich in iron. ’
After hearing what Zhao Zhongyao said, Feifei, Tiantian and Qu Yuqian looked towards the huge crater below. They feel that this crater is really huge, even if they are hundreds of kilometers away from the surface of Mercury. But it can still be felt that this crater is very large. And they are flying above this huge crater.
‘Dad, does this crater have a name! What is the name of this crater? Feifei looked at Zhao Zhongyao and asked.
Zhao Zhongyao heard Feifei’s words and said, ‘Of course, such a big crater naturally has a name. It is called a calorie crater. ’
After hearing what Zhao Zhongyao said, Feifei said strangely, ‘Dad, what are you talking about, it’s called a calorie crater. Is that what we call a calorie? ’
Zhao Zhongyao heard Feifei's words and said, ‘Yes, it’s the calorie per calorie. ’
‘Oh, that’s true. Then why is it called such a name! Feifei said puzzledly.
Zhao Zhongyao heard Feifei's words and just wanted to explain. I rushed to say every day, ‘Brother, you are so stupid, isn’t it because the crater is very hot! Therefore, this crater is called a calorie crater. Because this crater contains all calories. ’
‘Haha! Haha! Haha! ---’
With this explanation every day, Zhao Zhongyao, Feifei and Qu Yuqian laughed together. After all, Tiantian’s explanation sounds very funny.
‘Every day, you explain so well, you have answered your brother’s question very well for me. Zhao Zhongyao said with a smile looking at Tiantian.
Zhao Zhongyao piloted the spacecraft and took his family in a big circle in front of Mercury. They saw many impact craters and some big mountains. The surface of Mercury is similar to that of the Moon. But the composition of the two is completely different.
The moon is just a rocky planet, and there is basically no geological activity. The moon exists purely to control the speed of the earth's rotation.
This is not the case with Mercury. Mercury is an iron planet with a very high concentration. It is a planet composed of the planet's core material. Mercury originally has a shell. Only this shell, in an asteroid impact, this asteroid was picked up. Only such a Venus core remains.
Zhao Zhongyao took everyone to look at the front of Mercury, and everyone felt that there was nothing to look at. Feifei looked at Zhao Zhongyao and asked, ‘Dad, where do you say we should go to build amethyst gems. We came to Mercury, isn't it just to find amethyst gems! ’
After hearing what his son said, Zhao Zhongyao said, ‘Of course, we are looking for amethyst gems. It's just that we are now going to discuss where to find amethyst gems. ’
After hearing what my father said, Feifei thought for a while and said, ‘Dad, the amethyst gem we found on Venus is in an underground forest. Will there be such an underground forest on Mercury? ’
After hearing what Feifei said, Zhao Zhongyao said, ‘This is hard to say, this is Mercury. It's not Venus. What happens on Venus may not necessarily appear on Mercury. ’
‘Dad, do you think there is life on Venus? If there is no life, does that mean there will be no amethyst gems. Feifei felt that amethyst gems seemed to like to be with living things. It is like that on Venus, the amethyst gem is in an underground forest. And in this underground forest, there are also many kinds of creatures.
‘You’re right, if we want to find amethyst gemstones on Mercury, we can only find a living oasis first. Zhao Zhongyao felt that Feifei made sense. If they want to find amethyst gems on Mercury, they must first find an oasis of life.
‘Then where should we look for an oasis of life, whether there is an oasis of life on the planet Mercury? Feifei said again.
After hearing what Feifei said, Zhao Zhongyao thought for a while and said, ‘I feel that there must be an oasis of life on Mercury. If not, it would not appear that there is an amethyst gem on Mercury on the star map we see. Since the star chart has shown that there are some amethyst gems on Mercury, it means that there must be an oasis of life on Mercury. ’
‘What Dad said is, I also feel that since the star map has told us that there is an amethyst gem on Mercury, then we should be able to find an oasis of life on Mercury. Feifei said so after hearing what his father said.
After hearing what his son said, Zhao Zhongyao nodded and said, ‘Yes, I think so too. It's just that we should think about where the life oasis on Mercury will be. We are on Venus, although we have seen an oasis of life. But at that time, we found the underground forest by accident. But when we come to Mercury, can we still see an oasis of life by mistake? ’
After hearing what my dad said, Feifei said again, ‘dad, then you said we should go there to find an oasis of life. The front side of Mercury seems to have no life oasis! Is that an oasis of Mercury's life? It should be on the back of Mercury. ’
Feifei also felt that the front face of Mercury has a very high temperature, with an average temperature of more than 400 degrees. In such an environment, it is impossible for life to exist. The back of Mercury is different. Although the temperature on the back is very low. But in some special terrain, there might be a warmer and humid place where life can exist.
Zhao Zhongyao thought for a moment and said, ‘If Mercury has life, it should be on the back of Mercury. The front is unlikely to have life. We should go to the back of Mercury to find it now. ’
Okay, let's go to the back of Mercury to find it. Feifei said after hearing what his father said.
‘Okay, let’s go to the back of Mercury to find and try. After Zhao Zhongyao finished speaking, he drove the spacecraft to the back of Mercury again.
If you say on the front of Mercury, you can see the topography of Mercury's surface below. But it's different when you get to the back of Mercury. The back of Mercury is pitch black, and nothing can be seen. It is also very difficult to find life on the back of Mercury.
However, there are also lighting equipment on the spacecraft that Zhao Zhongyao and the others took. Even in the dark, searchlights can be used to provide illumination. Of course, even if it can be illuminated with a searchlight, it cannot fly too high.
If you fly too high, the searchlight on the spaceship is useless. After all, Mercury is a huge planet. The spacecraft flies in the dark night above a planet, just like a firefly flying in the dark. Although the light of the searchlight on the spaceship is also very bright. However, it can only reach a few hundred square meters on the ground. If you go further, you can't see clearly.
Zhao Zhongyao flew the spacecraft in the dark night against the background of Mercury. He is flying the spacecraft at an altitude of one kilometer above the ground. Because only at this height can we observe the conditions above the ground to the greatest extent. If you see an oasis of life, you can quickly discover it.
But Mercury is very big. A spaceship is compared to a planet. No matter how big the spacecraft is, it looks very small in front of a planet. Although the spacecraft driven by Zhao Zhongyao is also a very large spacecraft, it is obviously unusually small on the back of Mercury.
Zhao Zhongyao flew the spacecraft on the back of Mercury for a long time, but still did not find any signs of an oasis of life.
The back of Mercury, although in darkness. But under the shining of the spacecraft searchlight, everyone can see that the back and the front of Mercury are almost the same, they are all large and small impact craters. Apart from these things, there seems to be nothing special.
