Chapter 1 526 Mercury
If this plan can be implemented, then we can get a lot of electricity from Mercury for human use.
Regarding the matter of Mercury, I think I still want to give you some popular science. What kind of planet is this? I think if you don't particularly like astronomy, you won't know it very clearly.
‘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. One of the missions of this mission is to test this theory by analyzing the chemical composition of Mercury's entire surface. Mercury contains more iron than any other known galaxy planet. Here are several theories that have been proposed to explain the high metallicity of Mercury.
One theory is that Mercury originally had a metal-silicate ratio similar to that of ordinary chondrites. At that time its mass was approximately 2.25 times the mass we observed, but at some time in the history of the early solar system, a planetary microstellar body knocked off Mercury 16. The effect is that Mercury's crust and mantle are lost. Another similar theory is used to explain the formation of the Earth's moon, see the giant influence theory. On the other hand, Mercury may have stabilized in the early modeling stage of the so-called solar nebula before the sun burst its energy.
In this theory, Mercury was about twice the mass we observed at that time; but because of the contraction of the protostar, the temperature of Mercury reached between about 2500-3500K; even as high as 10000K. Many rocks on the surface of Mercury evaporate at this temperature to form "rock vapor", which is subsequently taken away by interstellar storms.
The third theory, similar to the second, is that the outer shell of Mercury has been eroded away by the solar wind for a long time. Mercury's appearance is like a moon, but the inside is very similar to the earth. It is also divided into three layers: crust, mantle, and core. The radius of Mercury is 2439 kilometers, which is 38.2% of the earth's radius. The combined 18 Mercury planets are the size of an earth. The mass is 3.33×10²⁶ g, which is 5.58% of the mass of the earth, and the average density is 5.433 g cm³, which is slightly lower than the average density of the earth.
Among the eight planets, except for the Earth, Mercury has the highest density. Astronomers speculate that Mercury's outer shell is made of silicate, and its center has an iron core much larger than the moon. The main components of this nuclear ball are iron, nickel and silicate. According to this structure, Mercury should contain two trillion tons of iron. According to the annual output of world steel (about 800 million tons), it can be mined 240 billion years. Two types of plains with significantly different geology.
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 the Mercury flat plains 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 the moon’s on Earth. Mercury’s density is the second most dense planet in the solar system, second only to the 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 current view of the scientific community is that in the early violent impact era of the solar system, Mercury suffered severe impacts, causing it to lose a part of its lower-density shell, thus leaving a relatively denser part. Among the eight planets in the solar system, Mars, Venus, Earth, Jupiter, and Saturn all have magnetic fields, but only Mercury is the only planet in the solar system that has a significant magnetic field besides the Earth. But despite this, its magnetic field strength is only less than 1% of the earth.
For a planet, the presence or absence of a magnetic field is by no means a trivial matter. Take the earth's magnetic field as an example. It forms an umbrella for life on the earth and helps to resist harmful sun rays and other cosmic rays, thus creating a paradise for life. Dr. Solomon referred to the earth's magnetic field as "our radiation umbrella." Without the earth's magnetic field, it would be difficult for life on earth to appear and evolve. Researchers believe that Mercury's magnetic field generation mechanism is the same as that of Earth, that is, the "motor" mode formed by the flow of conductive molten slurry in its outer core.
The messenger probe will accurately measure the distribution of Mercury's magnetic field to help scientists test whether this theory is correct. Mercury does have a dipole magnetic field. It was exactly one year from the initial discovery to the complete confirmation. The dipole magnetic field of Mercury is very similar to that of the Earth, with the same polarity, that is, the south pole of Mercury's magnetic field is in Mercury's northern hemisphere, and its north pole is in the southern hemisphere. There are more than 100 craters with radial stripes on the surface of Mercury and a large number of cliffs, some of which are hundreds of kilometers long. The density of Mercury is close to that of Earth, and it has a global magnetic field. The discovery of Mercury's magnetic field indicates that the interior of Mercury may be a high-temperature liquid metal core. The diameter of this heavy and large iron-nickel core is more than 13 the diameter of Mercury and the size of the entire moon.
The magnetic field strength of Mercury is only 1% of that of the earth, and the distribution pattern of magnetic field lines is simply a proportional microcosm of the earth's magnetic field. Mercury has a very thin atmosphere, with an atmospheric pressure of less than 2×10 hectopascals. The atmosphere contains elements such as helium, hydrogen, oxygen, carbon, argon, neon, and xenon. Because the atmosphere is very thin, the temperature of Mercury's surface during the day and night is very different. In fact, gas molecules in Mercury's atmosphere collide with Mercury's surface more frequently than they collide with each other. For these reasons, Mercury should be considered as having no atmosphere. ’
The above is some basic knowledge about Mercury. From this knowledge, we can see that Mercury is a perihelion planet locked by the solar tide. It is more than 4,000 kilometers in diameter, which is slightly larger than our moon. Only half the size of the earth.
Although Mercury is only half the size of Earth, it is a planet with extremely high elemental content of Venus. Therefore, his surface gravity is similar to that of the earth. In this case, if we are working on Mercury, we will feel lifting or weightlessness, and we will feel the gravity situation similar to that on Earth.
This is why I want to build a photovoltaic power station on Mercury, because Mercury has good light conditions. In addition, Mercury has a gravitational environment similar to that on Earth. These two points are the most important.
Although the atmosphere above Mercury is very thin. It can also be said that there is almost no atmosphere. The main reason why there is no atmosphere on Mercury is because it is very close to the sun. The strong gravitational force of the sun has long eroded the atmosphere on Mercury. Therefore, there is almost no atmosphere on Mercury, and it is completely a ‘vacuum’ environment.
But it doesn't matter whether there is an atmosphere on Mercury or not. Even if there is an atmosphere, it may be an atmosphere that can be used for human breathing. Taking a step back, even if there is a layer of oxygen on Mercury for humans to breathe. It is impossible for us humans to move on the surface of Mercury casually. Because of a very complex ecosystem on our planet. The level of complexity, not to mention that there is no second planet in the solar system that can be compared with the earth. Even if you look at the entire galaxy, it is difficult to find a second ‘earth’.
We must wear space suits if we want to work on Mercury. But no matter what, as long as there are conditions for us to build solar power stations on Mercury, we can build solar power stations on it.
But from the above information we have learned about Mercury, we can know that even though Mercury is called Mercury. In fact, he is a planet with a misnomer. Because there is no drop of water on Mercury.
In fact, this is also well understood. Not only is there no drop of water on Mercury now. There may not be a drop of water in its entire history. Because Mercury is very close to the sun. Only more than 57 million kilometers. This close distance makes the surface of Mercury very hot. Even if Mercury is locked by solar tides. The temperature is very high on the sunny side. But on the back side, the temperature is very low.
But regardless of the high temperature side, or the low temperature side. There is no such thing as water on Mercury. Don't say it is a planet like Mercury that is very close to the sun. Even on other planets far away from the sun, humans have not found a drop of water until now.
Therefore, it is impossible for us to work on Mercury without wearing a space suit. Not only wear a space suit but also a special space suit. Wear a space suit that can withstand high temperatures. We will redesign and develop these problems in the future.
Although the environment on Mercury is very harsh, it is not suitable for human survival. But the resources on Mercury are very rich. It not only has good light conditions, but also has a lot of metal elements. Mercury is actually called Venus.
We can not only build photovoltaic power stations on Mercury, but also develop metal resources on Mercury. Because of the environmental problems facing our planet, in addition to traditional energy problems, there is also the problem of metal resources.
When we humans on earth develop a large number of mineral resources, they also destroy the ecological balance of nature. We must recognize the serious problems we face. The energy problem is just one of the most serious of these serious problems.
In addition to the energy issue is the issue of metal resources. We can no longer hollow out the entire mountain for the metal resources in the rocks of the mountain. Our human activities on the surface of the earth have seriously affected the ecological environment on the earth.
In the future, we will not only build some large photovoltaic glass power plants on other planets in the solar system. In addition, the mineral resources on other planets and asteroids must be mined. We must keep all the resources on the earth from being exploited by humans. We want Mother Earth to truly recuperate.
Since the beginning of industrial civilization in human society, Mother Earth has become the object of human society's continuous search for resources and energy and willful destruction. We Feitian Group is not only an enterprise group, we must be a high-tech enterprise group with the mission of saving all mankind.
In the future, the tourist bases we build on each planet will not only be a tourist base, but more importantly, we will develop the resources on these planets.
Although in the solar system, there is only one planet such as the earth that has a life-sustaining ecosystem. There are many planets with various resources that humans can use. On any celestial body in the solar system, there are possible resources for us humans to use.
We humans must now understand that we can only unite. Then develop and utilize space resources together. Only in this way can we get out of the prison that science has compiled for us.
Now we all human beings are at such a critical moment. At this time, Feitian Group has to work harder. Because we are the most advanced high-tech enterprise in the world. We have the world's most advanced scientific research equipment and high-quality scientific research team.
Now only our Feitian Group has the most hope, leading the best scientific researchers of all mankind. Then break through the prison that science has created for us. Let us humans go out of the earth, to the solar system, and even more distant galaxies.
