Chapter 1144

If we look at the sun on earth, it looks like a hot little disc at noon, and it looks like an enlarged version of duck egg yolk in the morning and evening. What will the sun look like on mercury, which is closest to the sun?

From Lei Tiantang now pretends to be forced like emotion can hear out. Behoove the distance between mercury and the sun is the nearest in the whole solar system, so it is natural that the sun will make complaints about mercury on mercury.

In fact, the size of the sun on other planets is inversely proportional to the distance of the planet from the sun. Earth is 1 AU away from the sun, while Mercury is 0.387 Au from the sun.

If you look at the sun on mercury, it is 10.378 = 2.645 times of the earth. If you calculate the Pi of this number, you will get the figure of 8.31 times. So looking at the sun on mercury should be more than 8 times that of looking at the sun on earth.

But because Mercury has no atmosphere, it won't scatter sunlight. Therefore, although the sun is very big and the sun is very strong on mercury, it will not scatter and refract the sunlight due to the lack of atmosphere. The sky on mercury looks black, just like the color of the earth's night sky. Stars can be seen from the place facing the sun.

So Lei Tiantang behind that forced speech or nonsense, facing the sun is so big, you can see the stars is the hell!

Although the company has put two probes into the orbit of mercury, ray Tiantang put a lot of probes into the solar system on their last trip to Mars. Of course, Mercury also has them.

A total of 12 probes flew to mercury, and finally 9 of them successfully entered the orbit of mercury. Both Lei Tiantang and Kuafu were satisfied with the success rate. They would be surprised if they were 100% in orbit.

The large-scale launch of thousands of detectors, ray Tiantang, their psychological expectation is 80%. As long as 80% of the detectors can successfully complete the task, they will be satisfied. Even if the internal environment of the solar system is still safe, it does not mean that it is not at all dangerous.

All kinds of tiny space debris, the gravity of the sun and other planets, the failure of the detector itself and other factors will cause the loss of the detector. It's really good to have nine of them enter the orbit of mercury.

With these 10 satellites to provide detailed data to leitiantang, they don't have to go here to explore the data of mercury. After all, the size of mercury is so small, even smaller than that of Ganymede and Titan, the famous Titan.

What if it's bigger than all of them? The speed and efficiency of detector detection depends on its volume, not its mass, so the data provided by these 10 satellites is enough for Lei Tiantang to determine the construction location of the base before he came here.

After all, they only plan to build an outpost base on mercury, and they don't have to worry about the location of the site. Besides, as long as they don't have to choose the relatively risky places on mercury, there are no problems in any other places. Anyway, what they are building is just an underground base.

Mercury's underground environment is much better than Mars and Venus, although they are small, but they are solid! Why is mercury so massive? That's because people are made up of about 70% metal and 30% silicate material!

Mercury's density is 5.427 GCM? 3, which is the second highest in the solar system, second only to earth's 5.515 g cm? 3. If we do not consider the effect of gravity compression on the density of matter, the density of mercury material will be the highest - the density of mercury material without gravity compression is 5.3 g cm? 3, compared with 4.4 g cm? 3 of earth material.

Mercury's internal structure can be inferred from its density. The high density of the earth, especially the high density of the core, is caused by gravity compression, and mercury is so small that it won't be squeezed hard inside.

So if it is to have such a high density, its core must be very large. Its core mass can even account for 23% of its total mass, while the earth's core area mass only accounts for 13% of the total mass of the earth.

The main components of this nuclear sphere are iron, nickel and silicate. According to this structure, according to the data detected by the detector, the iron content of mercury may reach 200 billion tons. If the annual production of steel produced by the whole earth (about 800 million tons) is calculated, it can be mined for 240 billion years.

Of course, Lei Tiantang and Kuafu don't look down on these metal resources. There are more than 10 times more materials left by the small black hole body that devour the stellar system. Moreover, they can be used at any time. In this case, they will not exploit the gold resources here on a large scale.

However, after the construction of the underground base is completed, Kuafu can exploit some of his own if he is bored. Otherwise, the large energy of the nuclear fusion reactor is only used to maintain the normal operation of a base, which is a bit of a waste.

And even without considering its metal core, the crust layer that can be kept so close to the sun would have been evaporated by the sun if it was not strong enough.This is also the reason why Lei Tiantang landed directly at the selected position as soon as they entered the orbit of mercury. Although the temperature on the surface of the spacecraft would not cause any damage to the spacecraft, Lei Tiantang was not willing to stay for long in such a place so close to the sun.

Because after seeing it, it is easy for him to calculate in his mind how much his ability will increase if he devours it. What a terrible thing!

We should know that he is a native of the earth. He appeared only by this star, and all the human beings on the earth are inseparable from this star of life. Therefore, even if he can't bear to flash these data in his mind, he is not so crazy as to destroy the sun to bring himself a few capacity improvements.

In order to get rid of the influence of these thoughts, Lei Tiantang still decided to finish work early and finish work early. So after successfully leaving his footprints on mercury and retaining the evidence of his success in clocking, he started work directly, and his work attitude was not positive!

Because there is no need to build such a troublesome thing as the collider in this base of mercury, so the construction of the entire underground base is not too simple for Lei Tiantang and Kuafu, who are already proficient in business. It only took less than one day to complete the construction successfully.

Even when Kuafu is bored, the channels and processing space for mining and smelting ores are ready. It is also a good opportunity to test the self-sustaining ability of the underground base without replenishment for a long time.
