Chapter 1526 Mercury
If this plan can be implemented, then we can obtain a large amount of electrical energy from Mercury for human use.
Regarding this matter of Mercury, I think I still want to give you a popular science. What kind of planet is this, I think if you are not particularly interested in astronomy, you probably won't know very well.
‘Mercury is the planet with the most dense white bands in the solar system, second only to the earth. Based on this, scientists estimate that there must be a super-large core inside Mercury, and its core mass can even account for 2/3 of its total mass, while in contrast, the mass of the earth's core area only accounts for 1/3 of the total mass of the earth .
The view of the scientific community is that during the violent impact era in the early days of the solar system, Mercury suffered a severe impact, causing it to lose a part of its shell with a lower density, thus leaving a relatively denser part. One of the MESSENGER missions is to test this theory by analyzing the chemical composition of Mercury's entire surface. Mercury has a higher percentage of iron than any other known planet in the galaxy. Several theories have been proposed to account for Mercury's high metallicity.
One theory is that originally Mercury had a similar metal-silicate ratio to ordinary chondrites. At that time it was about 2.25 times the mass we observe, but at some point in the history of the early solar system, a planetesimal/micro-planet knocked off 1/6 of Mercury's mass. The effect is that Mercury's crust and mantle are lost. Another similar theory is one used to explain the formation of the earth's moon, see the theory of giant impact. Alternatively, Mercury may have stabilized in the early sculpting phase of the so-called solar nebula, before the sun burst out with its energy.
In this theory, the mass of Mercury was about twice what 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. Much of the rock on Mercury's surface evaporates at this temperature, forming "rock vapor," which is then carried away by interstellar storms.
The third theory, similar to the second, holds that Mercury's outer shell has been eroded by the solar wind for a long time. Mercury looks like the moon, but its interior is very similar to the earth. It is also divided into three layers: shell, mantle, and core. The radius of Mercury is 2,439 kilometers, which is 38.2% of the radius of the Earth. Only the combination of 18 Mercury is equal to the size of an Earth. The mass is 3.33x102? grams, which is 5.58% of the earth's mass, and the average density is 5.433 grams/cm3, which is slightly lower than the average density of the earth.
Among the eight planets, except the earth, Mercury has the highest density. Therefore, 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 sphere are iron, nickel and silicate. According to this structure, Mercury should contain two trillion tons of iron. Calculated according to the world's annual steel production (about 800 million tons), Mercury can be mined for 240 billion years. Two geologically distinct plains.
Between the craters, the gently rolling, hilly plains are the oldest visible regions on Mercury's surface, predating the violent crater topography. These cratered plains appear to have obliterated many older craters, and lack craters below 30 kilometers in diameter and smaller. It's unclear whether they are of volcanic or impact origin, but these buried plains are roughly evenly distributed across the planet's surface. Flat plains are extensive flat areas covered with depressions of various sizes, very similar to the moon's seas.
It is noteworthy that they are extensively encircled around the Calori Basin. Unlike the mare, Mercury's flat plains have the same albedo as the ancient, cratered plains. Despite the lack of definitive volcanic features, the localized platforms and rounded, split shapes strongly support the volcanic origin of these plains. It is worth noting that the formation of all Mercury flat plains is later than that of the Calori Basin. Comparing the density of small craters detectable on the calori eruptive overlay, it can be seen that the floor of the Calori Basin is filled with unique plain geology, Broken ridges and rough polygon shattering.
It's not clear whether the impact induced the lava, or whether the impact caused the massive melt. An unusual feature of the planet's surface are numerous compression folds, or cliffs, staggered across the surface of the plain. As the planet's interior cools, it likely shrinks slightly and the surface begins to deform, causing these features. Depressions are also seen on top of other terrain, such as pits and smooth plains, suggesting that these folds are only now forming. Mercury's surface 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 Mercury is the second densest planet in the solar system, after Earth.
Based on this, scientists estimate that there must be a super-large core inside Mercury, and its core mass can even account for 2/3 of its total mass, while in contrast, the mass of the earth's core area only accounts for 1/3 of the total mass of the earth . The current view of the scientific community is that in the violent impact era in the early days of the solar system, Mercury suffered a severe impact, causing it to lose a part of its shell with a lower density, 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 with a significant magnetic field among the terrestrial planets in the solar system besides the earth. But despite this, its magnetic field strength is only less than 1% of that of the earth.
For a planet, the presence or absence of a magnetic field is no small matter. Take the earth's magnetic field as an example, it constitutes the protective umbrella for life on the earth, helping to resist harmful solar rays and other cosmic rays, thus creating a paradise for life. Dr. Solomon called the earth's magnetic field "our radiation protection umbrella". Without the earth's magnetic field, it would be difficult for life on earth to emerge and evolve. Researchers believe Mercury's magnetic field generation mechanism and
The same as the earth, that is, the "motor" mode formed by the flow of conductive magma in its outer core.
The Messenger probe will precisely measure the distribution of Mercury's magnetic field, helping scientists test whether this theory is correct. Mercury does have a dipole magnetic field. It took exactly one year from initial discovery to full confirmation. The dipole magnetic field of Mercury is very similar to that of the earth, and the polarity is also the same, that is, the south pole of Mercury's magnetic field is in the northern hemisphere of Mercury, and its north pole is in the southern hemisphere. There are more than 100 craters with radial stripes and a large number of cliffs on the surface of Mercury, some of which are hundreds of kilometers long. Mercury has a density close to that of Earth and 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. This heavy and large iron-nickel core is more than one-third the diameter of Mercury and as large as the entire moon.
The strength of Mercury's magnetic field is only 1% of that of the Earth, and the distribution pattern of the magnetic force lines is simply a proportional miniature of the Earth's magnetic field. There is an extremely thin atmosphere on Mercury, the atmospheric pressure is less than 2x10 hPa, and 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 varies greatly between day and night. In fact, gas molecules in Mercury's atmosphere collide with the surface of Mercury more frequently than they collide with each other. For these reasons, Mercury should be considered without an atmosphere. '
The above is some basic knowledge about Mercury. From this knowledge, we can see that Mercury is a perihelion planet that is tidally locked by the sun. With a diameter of more than 4,000 kilometers, it is slightly larger than our moon. Only half the size of Earth.
Although Mercury is only half the size of Earth, it is a planet with a very high element content of Venus. Therefore, his surface gravity is similar to that of the earth. In this way, if we work on Mercury one day, we will feel the lifting or weightlessness, and we will feel the gravity similar to that on the earth.
This is also the reason why I want to build a photovoltaic power station on Mercury, because Mercury has good lighting conditions. In addition, Mercury has a gravitational environment similar to that on Earth, and 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, and the strong gravitational force of the sun has already 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 Mercury has an atmosphere or not. If there is an atmosphere, it may be an atmosphere that can be used by humans to breathe. Taking a step back, even if there is a layer of oxygen on Mercury that can be breathed by humans. It is also impossible for us humans to act casually on the surface of Mercury. Because of a very complex ecosystem on our planet. Its complexity, not to mention that there is no second planet in the solar system that can be compared with the earth. Even looking at the entire Milky Way, it is difficult to find a second 'Earth'.
If we're going to work on Mercury, we must be wearing spacesuits. But no matter what, as long as there are conditions for us to build a solar power station on Mercury, we can build a solar power station on it.
But from some of the information about Mercury we have learned above, we can know that Mercury is called Mercury. In fact, he is a planet that does not live up to its name. Because there is no drop of water on Mercury.
In fact, this is also very well understood. Not only is there no drop of water on Mercury now. There may not have been a single drop of water in its entire history. Because Mercury is very close to the sun. Only over 57 million kilometers. Such a short distance makes the surface temperature of Mercury very high. Even if Mercury is tidally locked to the sun. The temperature is very high on the sunny side. But on the side of the back, the temperature is very low.
It doesn't matter whether the temperature is high or the temperature is low. There is no such thing as water on Mercury. Let alone Mercury, a planet that is very close to the sun. Even on other planets farther from the sun, humans have not found a drop of water so far.
Therefore, it is impossible for us to work on Mercury without wearing a spacesuit. Not only to wear a space suit but also to wear 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. Not only have good lighting conditions, but also a lot of metal elements. Mercury is actually called Venus is more appropriate.
We can not only build photovoltaic power stations on Mercury, but also develop metal resources on Mercury. Because the environmental problems facing our earth, in addition to the traditional energy problems, there is also the problem of metal resources.
When humans on our earth develop a large amount 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 energy issues is the issue of metal resources. We can no longer hollow out the entire mountain for the metal resources in the mountain rock. 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-scale photovoltaic glass power stations on other planets in the solar system. In addition, mineral resources on other planets and asteroids must be mined. We must prevent all resources on the earth from being exploited by humans. We need to let Mother Earth really rest.
Since human society started industrial civilization, Mother Earth has become the object of human society's constant search for resources and energy and willful destruction. Our Feitian Group is not only an enterprise group, we must be a
A high-tech enterprise group with the mission of saving all mankind.
In the future, the tourist bases we build on each planet are not just tourist bases, but more importantly, we want to develop the resources on these planets.
Although the earth is the only planet in the solar system that has a life-sustaining ecosystem. There are many planets that can have various resources that humans can use. On any celestial body in the solar system, there are resources that may be used by us humans.
We humans must now understand that we are only united. Then develop and utilize space resources together. Only in this way can we get out of the cage that science has made for us.
All of us are now at such a critical moment. And our Feitian Group must work harder at this time. 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 is the most promising, leading the best scientific researchers of all mankind. Then break through the cage that science has made for us. Let us humans go out of the earth, to the solar system, and even to more distant galaxies.
