Chapter 1572: Fly to Mercury

Chapter 1760 Flying to Mercury
After hearing what Zhao Zhongyao said, Feifei thought for a while and said, "Dad, so to speak, the star map we see now is the most accurate star map. In the future, we can explore according to this star map. Up. ’
After hearing what Feifei said, Zhao Zhongyao said, ‘Yes, we’ll just be able to explore according to this star map in the future. In this way, we can quickly find those twelve amethyst gems. ’
‘Ok, then let’s move on! Feifei smiled.
‘Next stop, Mercury. "Zhao Zhongyao began to drive the spacecraft to accelerate to Mercury.
The closest distance from Venus to Mercury is more than 50 million kilometers, and the farthest is 160 million kilometers. But for the flying saucer spacecraft that Zhao Zhongyao and the others took, this distance was nothing. The spacecraft they pilot can fly to Mercury in no time.
Now Zhao Zhongyao is flying to Mercury in his spacecraft. Although flying from their place to Mercury, it may take more than 100 million kilometers. After all, at this time, Venus is relatively far away from Mercury.
But for the spacecraft that Zhao Zhongyao was driving, this distance was nothing. Their spacecraft can still fly there soon.
On the way to Mercury, Feifei looked at Zhao Zhongyao and asked, ‘Dad, what kind of planet is Mercury. There should be no water on Mercury! ’
After hearing what Feifei said, Zhao Zhongyao smiled and said, ‘Although Mercury is called Mercury, there can be no water on it. Mercury is a very hot planet. Of course, this refers to the side of Mercury facing the sun. And the side of Mercury facing away from the sun is not only not fiery. On the contrary, the temperature of Mercury's side facing away from the sun is very low. ’
After hearing what Zhao Zhongyao said, Feifei said again, ‘Dad, can you tell us about Mercury? I want to know something about Mercury first. ’
After hearing what his son said, Zhao Zhongyao said, ‘Okay then! Let me tell you something about Mercury. ’
Next, Zhao Zhongyao told his son some knowledge about Mercury.
The surface of Mercury is much like the moon, full of craters, great plains, basins, radiation patterns and cliffs. In 1976, the International Astronomical Union began to name the craters on Mercury. On the surface of Mercury, there are scattered large and small craters, including high mountains, plains, and frightening cliffs.
According to statistics, there are thousands of craters on Mercury, and these craters have a gentler than those on the moon. The average surface temperature of Mercury is about 452K, with a range of 90-700K, which is the planet with the largest temperature difference. In the daytime, the temperature under direct sunlight is as high as 427℃, and when the sun is not in the night, the temperature drops to -173℃. It can be compared to the earth, the temperature change on the earth is only 11K (here only the solar radiation energy, without considering the "season" and "weather").
The sunlight on the surface of Mercury is 8.9 times stronger than that of the earth, and the total irradiance is 9126.6W㎡. Surprisingly, radar observations conducted in 1992 showed that Mercury’s north pole had ice. It is generally believed that these ices exist at the bottom of craters where sunlight can never reach, and accumulate due to the impact of comets or the emergence of gas from inside the planet. Because there is no atmospheric regulation, the temperature in these places has been maintained at minus 280 degrees Fahrenheit (about -173 degrees Celsius). The surface of Mercury exhibits huge sharp slopes, some reaching hundreds of kilometers in length and 3,000 meters in height. Some lie across the outer ring of the crater, while the appearance of some steep slopes indicates that they are formed by compression.
It is estimated that the surface of Mercury has shrunk by about 0.1% (or decreased by about 1 km in the radius of the planet)! The surface of Mercury has been hit by numerous meteorites, with craters everywhere. When Mercury is hit by a huge impact, a basin will form, surrounded by mountains. Outside the basin is the material ejected from the impact and the flat lava torrent plain.
In addition, during the evolution of Mercury over billions of years, many folds, ridges and cracks have been formed on the surface, which are intertwined with each other. The craters of Mercury are very similar to the moon. One of the most notable features of Mercury's surface (including only the parts that have been photographed) is an impactful crater with a diameter of 1360km:
Calorie Basin is the hottest area on Mercury. Like the basin of the moon, the calorie basin is likely to be formed in the early collision of the solar system. That collision probably also caused the peculiar topography of the basin on the other side of the planet.
The terrain of Mercury is marked as undulating because of the wrinkling of the outer shell caused by the cooling and contraction of Mercury's core billions of years ago. The surface of most Mercury consists of two different age layers; the younger ones are flatter, perhaps due to the lava immersed in earlier terrain. In addition, Mercury has "significant" "cyclical expansion".
Observing Mercury from the ground, you can barely see its details. The surface of Mercury is dotted with large and small craters, ranging from high mountains to plains, as well as frightening cliffs. According to statistics, there are thousands of craters on Mercury, and these craters have a gentler than those on the moon.
Mercury is a planet with many dense white belts in the solar system, second only to Earth. Based on this, scientists estimate that there must be a super-large inner core inside Mercury, whose inner core mass can even account for 23 of its total mass. In contrast, the mass of the earth's inner core area only accounts for 13 of the total mass of the earth. The view of the scientific community is that in the early violent impact era of the solar system, Mercury suffered a severe impact, causing it to lose a part of its lower-density outer shell, thus leaving a relatively denser part.
Mercury has two distinctly different geological plains. Between the pits, the gently undulating, hilly plain is the oldest area visible on the surface of Mercury, predating the fierce crater terrain. These plains with craters seem to have obliterated many of the earlier craters and lacked craters below 30 kilometers in diameter and smaller. It is not clear whether they originated from volcanoes or impacts. These plains with craters are roughly evenly distributed across the surface of the planet. A flat plain is a wide flat area, full of depressions of various sizes, very similar to the lunar sea.
It is worth noting that they surround the Kalori Basin extensively. Unlike the Moon Sea, the flat plains of Mercury have the same albedo as the ancient plains with craters buried. Despite the lack of clear volcanic features, the geochemical platforms and rounded corners and split shapes strongly support the origin of these plains from volcanoes. It is worth noting that all Mercury flat plains were formed later than the Calorie Basin. Compared with the density of small craters detectable on the Calorie eruption cover, it can be seen that the floor of the Calorie Basin is filled with unique plain geology. Broken ridges and fragmented rough polygons.
It is not clear whether the impact induced volcanic lava or the impact caused large areas of melting. An unusual feature of the planet's surface is the numerous compression folds or cliffs staggered across the plain surface. As the planet's interior cools, it may shrink slightly and the surface will begin to deform, causing these features. Depressions are also found in other terrain, such as pits and smooth plains. Seen at the top, it shows that these folds were formed only now. The surface of Mercury is also distorted by the sun-the sun's tidal force on Mercury is 17 times stronger than that of the moon on Earth.
Zhao Zhongyao now tells his son some knowledge about Mercury. After Feifei listened, he felt that Mercury is a planet with no fun. Relatively speaking, it may be more fun on Venus.
‘Dad, there seems to be nothing fun on this Mercury! It's just a deserted and silent planet like the moon. Feifei looked at Zhao Zhongyao and said.
After hearing what his son said, Zhao Zhongyao said, ‘What kind of planet Mercury is, we can only know after we get to Mercury. Now we can’t say what kind of planet Mercury is.
Before, we thought that Venus was on earth. But when we actually landed on Venus, we did not accidentally discover an underground forest. Inside, there are all kinds of prehistoric animals.
Although Mercury is very close to the sun. But Mercury is locked by solar tides. He faces the sun, and the temperature is more than 400 degrees. But on the side facing away from the sun, the temperature is very low. It can be said that Mercury is a world of ice and fire. This point may be different from Venus. Almost all of the surface of Venus is hellfire. But this is not the case on the surface of Mercury. ’
‘Dad, having said that, after we get to Mercury, there may be some unexpected discoveries. After we get to Mercury, will we still see some magical creatures? Feifei looked at Zhao Zhongyao again and said.
‘This is hard to say, but since we can find life on Venus. It is possible to find life on any other planet. ’
Zhao Zhongyao felt that Mercury was very close to the sun. But it is a big planet after all, and compared to a single life, there are many places on a planet where they can live alone.
‘Dad, then when we go to Mercury this time, we should also find some magical life! Feifei said again.
‘I hope so! If there is no magical life, wouldn't it be meaningless if we go to any planet? In fact, life should be ordinary matter in the universe. There should be traces of life on any planet.
Of course, not every planet can have advanced intelligent human beings like the earth. But on some planets, there should be some low-level life, which is very possible. Zhao Zhongyao said again.
‘Dad, let’s go to Mercury now! I want to see what life on Mercury looks like. After Feifei was on Venus, after that expedition, he became more and more interested in extraterrestrial life.
‘Okay, let’s go and see on Mercury. I feel that there should be life on Mercury. Said Zhao Zhongyao.
‘Why, why does Dad think so! Feifei asked the same.
‘Yes, since we found the place where the amethyst gem stayed on Venus, there are many magical lives. On Mercury, there is also an amethyst gem. On Mercury, there should not be magical life. ’
From the environment where Venus’s amethyst gems existed, Zhao Zhongyao wondered if there should be life on Mercury if there were amethyst gems.
Feifei felt very reasonable after hearing what his father said. Since amethyst gems are always connected to life, if there are amethyst gems on Mercury. There should also be life.
He didn’t say anything for a long time. When he heard his father and brother talk about the relationship between the amethyst gemstone on Venus and life, she interjected and said,
Dad, so to speak, That piece of underground forest. The reason why it exists is related to this amethyst gem. Many creatures there are also related to this amethyst gem. If we take this amethyst gem away now, will the life on the Venus be affected? ’
After hearing what Tiantian said, Zhao Zhongyao said, ‘This shouldn’t have much impact. After all, the underground forest on Venus is a separate world. It has nothing to do with the environment of Venus. And, we only used this amethyst gem. After we use it, we will put this amethyst gem back. In this way, there will be no impact on life on Venus. ’
Hearing what Dad said every day, he also nodded. I feel that what Dad said makes sense. They just used this amethyst gem temporarily. After they use it, they will put this amethyst gem back.
Now Zhao Zhongyao is flying the spacecraft to Mercury again. It's just that if they fly to Mercury in this way, it's almost as if they fly directly to the sun.
At this time, Feifei looked at her dad jokingly and said, ‘Dad, are we considered as moths fighting the fire! ’
After hearing what Feifei said, Zhao Zhongyao was taken aback for a moment. He didn't understand what Feifei meant.
‘Feifei, what do you mean by that. Aren't we flying to Mercury! Zhao Zhongyao looked at Feifei and said.
‘Dad, aren’t we flying towards the sun too! And isn’t the sun just a huge fireball! We do this, isn't it just moths fighting the fire! Feifei said again.
After hearing what his son said, Zhao Zhongyao understood what it meant to say that this moth extinguished the fire. So Zhao Zhongyao also smiled and said, ‘haha, what you described is so good, we are like a moth, flying towards a big fireball. ’
I listened to the conversation between my father and my brother every day, and I also joked, ‘dad, then you can get a good direction. Don't let us fly directly to the sun. ’
After hearing what Tiantian said, Feifei smiled and said, ‘Sister, what are you talking about! Don't you worry about Dad's driving skills! ’
