Chapter 1529: The Superior Conditions of Mars
I think that only when most of us humans can go to space to see, they will cherish the earth we have now. Otherwise, they will feel that the carrying capacity of our planet is unlimited.
I think we are launching solar system tourism adventure activities this time. Not only must a tourist route be developed. It is also an educational opportunity for human beings. I want more people on Earth to leave the earth and go to space to see. At that time, when they get into space and see other planets are barren, they will cherish our earth even more.
When everyone leaves the earth and arrives in space, they will feel that our earth is actually very small. Not what we feel on earth at all. If we have been on the earth and have never been in space, we would never feel the vastness of space, nor the smallness of our earth.
We can only feel the insignificance of our earth when we are in space, tens of thousands of kilometers away from the earth. After all, the earth is just one of the many planets in the solar system. Although it is considered a relatively large planet, it is really not a very large planet in the entire solar system.
The earth is really precious. When you go to space and see other planets are barren or on earth like Venus. You will truly feel how precious our earth is.
But anyway, the resources on our planet are limited, and our human population is growing at an extremely fast rate. At this rate, we people on Earth could exceed 10 billion in more than ten years. And the resources on our planet will not increase, but will only decrease.
Under such circumstances, we humans want to survive on earth forever. In addition to going to outer space to find new resources needed for survival and to open up another living space, we have no other way to go.
Now we have excluded Mercury and Venus. In addition to the earth, the next planet we are looking for is Mars. On the surface, Mars is the most suitable planet for human habitation. Although it is much smaller than the earth, its surface area is similar to that of the earth's land. And its surface temperature is still very suitable for human living on the earth. Although its temperature is only such a high temperature when Mars is summer, there is no such high temperature on planets in the solar system other than the Earth.
To talk about this Mars, we need to know more about the knowledge of this Mars. Mars has a diameter of about half of the Earth, a volume of 15%, a mass of 11%, a surface area equivalent to the land area of ​​the earth, and a density higher than the other three. The terrestrial planets (Earth, Venus, Mercury) are much smaller.
In terms of radius, mass, and surface gravity, Mars is approximately between the earth and the moon; the diameter of Mars is about twice the moon and half the earth; the mass is about nine times that of the moon, 19 times that of the earth, and the surface gravity is about 2.5 that of the moon. Times, 25 of the earth. Mars is the fourth planet in the solar system from the inside to the outside. It belongs to the terrestrial planet. Its diameter is about half the diameter of the earth. It takes twice as long for the rotation axis inclination and the rotation period to make one revolution.
In the West, it is called Mars, the of war, and in China, it is called the star of the planet, because it glows like fire, and its position and brightness often change. Its orange-red appearance is because the surface is covered by hematite (iron oxide). The prefix in English is Mars. Mars was once considered the most likely planet in the solar system for extraterrestrial life.
Mars is basically a desert planet with sand dunes and gravel everywhere on the surface. There is no stable liquid water body. The atmosphere dominated by carbon dioxide is thin and cold, with sand and dust suspended in it, and dust storms often occur every year. Compared with the earth, geological activities are not active, and another unique topographical feature is the obvious difference between the northern and southern hemispheres: the south is an ancient highland full of craters, and the north is a younger plain. Mars has two poles mainly composed of water and ice. It is composed of a polar cap, and the dry ice covered on it will increase and decrease with the seasons. The close distance is about 55 million kilometers, and the longest distance is more than 400 million kilometers.
Close contact between the two occurs approximately once every 15 years. In 1988, the distance between Mars and the Earth reached approximately 58.8 million kilometers, and in 2018 the distance between the two will reach 57.6 million kilometers. But on August 27, 2003, the distance between Mars and the Earth was only about 55.76 million kilometers, the most recent in 60,000 years. However, according to astronomers, in the 800 years from 1600 to 2400 AD, the close distance between Mars and the Earth can only be ranked third.
According to the calculation results, by September 2, 2366, the distance between the two will be about 55.71 million kilometers. By August 28, 2287, the two will be closer, with a distance of about 55.69 million kilometers. Generally speaking, the year when Mars and the Earth are close is the most suitable time to land on Mars and observe Mars on the ground. Mars is called the God of War in the West, which may be due to its bright red color, so Mars is sometimes called the "red planet".
Before the Greeks, the ancient Egyptians worshipped Mars as the of farming. Later, the ancient Greeks regarded Mars as the of war Ares, while the ancient Romans inherited the Greek mythology and called it "the of war Mars." In Norse mythology, Mars is the of war Tyr.
The name of the month March is also derived from Mars. Mars was called "fluorescent planet" in ancient China. This is because Mars is red and fluorescent like fire. It symbolizes fire in the five elements. Its brightness often changes; and it moves in the sky, sometimes from west to east, sometimes from east to west. The situation is complicated and confusing, so ancient China called it "Yingzhuo", which means "fluorescent fire light, chaos and confusion".
The density of the atmosphere of Mars is only about 1% of that of the earth. It is very dry and has a low temperature. The average surface temperature is minus 55°C. Water and carbon dioxide are easy to freeze. In the early days of Mars, it was very similar to Earth. Like Earth, almost all of the carbon dioxide on Mars is converted to carbonaceous rocks.
However, due to the lack of plate movement of the earth, Mars cannot recycle carbon dioxide into its atmosphere, and thus cannot produce a significant greenhouse effect. Therefore, even if it is pulled to the same distance as the earth from the sun, the temperature on the surface of Mars is still much colder than that on the earth. The thin atmosphere of Mars is mainly composed of leftover carbon dioxide (95.3%) plus nitrogen (2.7%), argon (1.6%) and trace amounts of oxygen (0.15%) and water vapor (0.03%).
The average atmospheric pressure on the surface of Mars is only about 7 mbar (less than 1% on Earth), but it varies with altitude, reaching up to 9 mbar in the deepest part of the basin, while in Olympus The top of the mountain is only 1 millibar. But it is also sufficient to support hurricanes and major storms that occasionally sweep the entire planet throughout the month. Although the thin atmosphere of Mars can also create the greenhouse effect, those that can only raise the temperature of its surface by 5°C are much less than what we know about Venus and the Earth.
The poles of Mars are permanently covered by solid carbon dioxide (dry ice). The structure of this ice cover is layered, it is formed by alternately superimposing a layer of ice and a layer of changing carbon dioxide. In the northern summer, the carbon dioxide is completely sublimated, leaving a remaining layer of ice water. Since carbon dioxide in the south has never completely disappeared, we cannot know whether there is an ice water layer under the ice in the south.
The reason for this phenomenon is not yet known, but it may be caused by long-term changes in the angle between the equatorial plane of Mars and its orbit. Perhaps there is also water deep below the surface of Mars. This change in the overlying layers of the poles caused by seasonal changes has changed the atmospheric pressure of Mars by about 25%. However, observations through the Hubble Telescope indicate that the Viking environment was not typical at that time. The atmosphere of Mars appears to be colder and drier than the Viking surveyed.
The orbit of Mars is elliptical. Therefore, the temperature difference between the perihelion and the aphelion is nearly 160 degrees Celsius in a place exposed to the sun. This has a huge impact on the climate of Mars. The average temperature on Mars is about 218K, but it has a span from 140K in winter to nearly 300K in daylight in summer. Although Mars is much smaller than the Earth, its surface area is equivalent to the land area of ​​the Earth's surface.
Mars is the most likely planet in the solar system besides Earth. Therefore, astronomers on our planet are also trying hard to find traces of life on Mars. But no matter how hard we try. Mars does not seem to give us a satisfactory answer.
Some people say that although Mars has no signs of life now, it may have signs of life in the distant past. After all, human Mars probes have seen many dry river beds on Mars. Although there is no drop of water on these riverbeds. But if these things like riverbeds are really rivers where Mars passed away, then life may have appeared on Mars.
But these things still need to be further proved by human beings. This time we are going on a solar system tourism and expedition mission, when that time, we will definitely go to see on Mars. We must solve the mystery of life on Mars.
Of course, we have to treat Mars differently. Mars is the most valuable planet besides the earth. It is entirely possible for us humans to live on Mars in the future.
Mars is the planet that we humans most anticipate to be the next earth in the solar system. This time our solar system travel expedition will also regard Mars as an important expedition destination. We will definitely stay on Mars for a while and take a field trip to this fiery red planet.
Mars is very attractive to us on Earth. If we can transform Mars into a new home for mankind, even if the number of people on our planet doubles, we can live on Mars.
So, we Feitian Group will do the next major project. The transformation project on Mars will be an extraordinary and major super project that Feitian Group may do in the next few decades.
It is theoretically possible to transform Mars. Because there are already conditions on Mars that initially allow life to exist. And now if we want to transform Mars. The first is to create an ocean on the surface of Mars.
This is like building a lunar city on the moon. We can also create artificial oceans on Mars. However, to create an artificial ocean on Mars is not as easy as building a lunar city on the moon to create an artificial ring sea.
Although Lunar City is a super project. But compared with our project to transform Mars, it may be nothing. Because it is really a very ambitious project to transform Mars. This project can be said to be the most ambitious project in human history.
To transform Mars, we must first create an artificial ocean on Mars. This is a very difficult thing. However, we can completely imitate how the earth had a lot of water resources in the early days. Use comets in the solar system to create artificial oceans on Mars. Because our earth did not have water in ancient times. And the water resources on the earth are all because the earth was visited by comet meteor shower many times in ancient times. Then, the earth has a lot of water resources, and finally a lot of water resources are formed on the earth, which provides a material foundation for the reproduction of life.
Although there are not many comets we can see. There are no comets in low earth orbit. But in the entire solar system, there are many comets. These things like dirty earth can be said to be everywhere in the outer space far from the solar system.
That huge Oort cloud was formed by the gathering of countless dirty snowballs of endless sizes. And all the comets we see may be comets flying from this huge Oort cloud to near the earth.
It's just that this Oort cloud is a little too far away from the earth. This huge solid ‘reservoir’ is half a light-year away and one light-year away from the earth. Such a long distance is beyond the reach of human beings on earth. Even if we now have a super spacecraft, it is obviously impractical to fly so far to transport the comets there to Mars.
In fact, it's not just that there are many comets in the Oort Cloud. Even the Kuiper Belt outside Pluto has many comets. How did these comets come from? No one can understand it now. There is a most reliable saying that these comets are all from the Oort Cloud. It is just that when they fly near the sun, they are attracted by the gravity of the solar system and become a near-Earth asteroid flying around the sun.
