Chapter 1529 The Superior Conditions of Mars

I think that only when most of us humans can also go to space to see, they will appreciate the earth we have now even more. Otherwise, they will feel that the carrying capacity of our planet is infinite.

I think, our solar system tourism expedition this time. Not only to develop a tourist route. It is also an educational opportunity for humanity. I want more people on earth to leave the earth and go to space to see. At that time, when they go to space and see that other planets are barren, they will cherish our earth even more.

When you leave the earth and go into space, you will feel that our earth is actually very small. Not at all how we feel on Earth. If we had been on the earth and never been in space, we would not feel the vastness of space at all, nor the insignificance of our earth.

Only when we are in space, tens of thousands of kilometers away from the earth, can we feel the insignificance of our earth. After all, Earth is just one of many planets in our solar system. Although it is considered a relatively large planet, it is really not considered a large planet in the entire solar system.

The earth is really too precious. When you go into space and see other planets are barren or hell on earth like Venus. You will really feel how precious we are on this earth.

But in any case, the resources on our earth are limited, and our human population is growing at an extremely fast rate. At this speed, we earthlings may exceed 10 billion in a dozen years. And the resources on our earth will not only not increase, but will only decrease.

Under such circumstances, we humans want to survive on the earth forever. Then we have no other way to go except to go to the outer space to find the resources needed for new survival and to develop another living space.

Now we rule out Mercury and Venus. Then the next planet we are looking for is Mars besides the Earth. Mars is a large surface, the most suitable planet for human habitation. Although its size is much smaller than that of the earth, its surface area is about the same as that of the earth's land surface. And its surface temperature is still very suitable for human habitation on earth. Although its temperature is so high only during the summer of Mars, it is not such a suitable temperature for human habitation on planets other than the earth in the solar system.

To talk about this Mars, we need to know more about this Mars. The diameter of Mars is about half that of the Earth, 15% of the volume, 11% of the mass, the surface area is equivalent to the land area of ​​the Earth, and the density is higher than the other three planets. The terrestrial planets (Earth, Venus, Mercury) are much smaller.

In terms of radius, mass, and surface gravity, Mars is about halfway between the Earth and the Moon; the diameter of Mars is about twice that of the Moon, half that of the Earth; its mass is about nine times that of the Moon, 1/9 that of the Earth, and its surface gravity is about the same as that of the Moon 2.5 times that of the earth, 2/5 of the earth. Mars is the fourth planet from the solar system from the inside to the outside. It belongs to the terrestrial planet. Its diameter is about half that of the Earth, and its rotation axis inclination and rotation period are similar, and it takes twice as long to complete a revolution.

In the West it is called Mars, the God of War, and in China it is called Yinghuoxing because it is glowing like fire, and its position and brightness change from time to time. Its orange-red appearance is because the surface is covered with hematite (iron oxide), and the prefix in English is Mars. Mars was once considered the most likely planet in the solar system to have extraterrestrial life.

Mars is basically a desert planet, with sand dunes and gravel all over the surface, and no stable liquid water. The atmosphere mainly composed of carbon dioxide is thin and cold, and dust is suspended in it. Dust storms often occur every year. Geologically inactive compared to Earth, another unique topographical feature is the stark difference between the northern and southern hemispheres: ancient, cratered highlands to the south, and younger plains to the north. Both poles are dominated by water and ice. The polar cap, and the dry ice covering it will grow and decline with the seasons. The short distance is about 55 million kilometers, and the longest distance is more than 400 million kilometers.

Close encounters between the two occur approximately every 15 years. In 1988, the distance between Mars and Earth once reached about 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, which was the closest in 60,000 years. However, according to astronomers' calculations, during the 800 years from 1600 AD to 2400 AD, the short 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. And 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 Earth are close is the most suitable time to land on Mars and observe Mars on the ground. Mars is known in the West as the god of war, perhaps because of its bright red color, so Mars is sometimes called the "red planet".

Before the Greeks, the ancient Egyptians worshiped Mars as the god of agriculture. Later, the ancient Greeks regarded Mars as the god of war Ares, and the ancient Romans inherited the mythology of the Greeks and called it "Mars, the god of war". In Norse mythology, Mars is Tyr, the god of war.

The name of the month March is also derived from Mars. Mars was called "Ying Huo Xing" in ancient China. This is because Mars is red and fluorescent like fire, which 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 "Yinghuo", which means "Yingyinghuoguang".

, from the meaning of chaos and confusion".

The density of the atmosphere on Mars is only about 1% of that of the Earth. It is very dry and the temperature is low. 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, nearly all of the carbon dioxide on Mars is converted into carbon-containing rocks.

But without Earth's plate tectonics, Mars is unable to recycle carbon dioxide into its atmosphere to produce a meaningful greenhouse effect. Therefore, even pulling it to the same distance from the sun as Earth, the temperature on the surface of Mars is still much colder than that on Earth. The thin atmosphere of Mars is mainly composed of leftover carbon dioxide (95.3%) plus nitrogen (2.7%), argon (1.6%) and traces of oxygen (0.15%) and water vapor (0.03%).

The average atmospheric pressure on the surface of Mars is only about 7 millibars (less than 1% of that on Earth), but it varies with altitude, reaching as high as 9 millibars in the deepest basins and up to 9 millibars in Olympus The top of the mountain is only 1 millibar. But it's also big enough to support occasional hurricanes and major storms that rip through the planet all month long. The thin atmosphere of Mars can also create a greenhouse effect, but those can only increase the temperature of its surface by 5 ℃, much less than what we know about Venus and Earth.

The poles of Mars are permanently covered in solid carbon dioxide (dry ice). The structure of this ice cover is cascaded, and it is formed by alternate superimposition of ice layers and changing carbon dioxide layers. During the northern summer, the carbon dioxide sublimes completely, leaving behind a remaining layer of icy water. Since the carbon dioxide in the south never completely disappears, we have no way of knowing whether there is a layer of ice water under the ice in the south.

The reason for this phenomenon is not known, but it may be due to climate change caused by long-term changes in the angle between the equatorial plane of Mars and its orbit. There may also be water deep below the surface of Mars. This change in the polar cover due to seasonal changes changes the air pressure on Mars by about 25%. However, observations through the Hubble Telescope have shown that the environment that the Viking was surveying at the time was not a typical situation. Mars' atmosphere appears to be cooler and drier than Viking's surveys have measured.

The orbit of Mars is elliptical. Therefore, the temperature difference between perihelion and aphelion is nearly 160 degrees Celsius in places receiving the sun's rays. 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 summer daytime. Although Mars is much smaller than Earth, it has a surface area equivalent to that of Earth's landmass.

Mars is the planet most likely to host life in the solar system, other than Earth. Therefore, astronomers on our earth are also working 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 there are no signs of life on Mars now, there may be signs of life in the distant past. After all, human Mars probes have seen many dry river beds on Mars. Although not a drop of water can be seen above these riverbeds. But if these riverbed-like things are really rivers in the distant past of Mars, then life may have appeared on Mars.

But these things still need to be further proved by human beings. For our solar system tourism exploration mission this time, we will definitely go to Mars to see it when the time comes. We're definitely going to solve the mystery of life on Mars.

Of course, we have to treat Mars differently. Mars is the most useful planet for us humans besides the earth. It is entirely possible for us humans to live on Mars in the future.

Mars is the planet that we humans are most looking forward to becoming the next earth in the solar system. Our solar system travel expedition this time will also regard Mars as an important research destination. We will definitely stop on Mars for a while and do a field trip to the fiery red planet.

Mars is very attractive to us earth humans. If we can transform Mars into a new home for mankind, then even if the population of our planet is doubled, we can also live on Mars.

So, in the major project that our Feitian Group will do next. The transformation project on Mars will be an extraordinary and major super project that our 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 step is to create an ocean on the surface of Mars.

This is like building a moon 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 moon city on the moon and creating an artificial ring-shaped sea.

Although Moon City is considered a super project. But compared with our project to transform Mars, it may be nothing. Because it is really a very grand project to transform Mars. This project can be said to be the most ambitious project in human history.

If we want to transform Mars, we must first create an artificial ocean on Mars. This is a very difficult thing to do. However, we can completely imitate how the earth had a lot of water resources in the early days. Using comets from our solar system to create an artificial ocean on Mars. Because our earth did not have water in ancient times. The water resources on the earth are all because the earth has suffered many comet meteor showers in ancient times. Then, let the earth have a lot of water resources, and finally formed a lot of water resources on the earth, providing a material basis for the reproduction of life.

Although there are not many comets that we can see. There are no comets in low earth orbit. But in the entire solar system, there are a lot of comets. These dirty earth-like things can be said to be everywhere in the space far away from the solar system.

That huge Oort cloud is formed by the gathering of countless dirty snowballs of various sizes. And all the comets we see may be comets that flew near the earth from this huge Oort cloud.

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 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 unrealistic to fly so far to transport the comet there to Mars.

In fact, it is not just that there are many comets in the Oort cloud. Even the Kuiper belt outside of Pluto is full of comets. Where did these comets come from? No one can explain it now. One of the most reliable sayings is that these comets all come from the Oort cloud. Just because they are attracted by the gravitational force of the solar system when they fly near the sun, they become a near-Earth asteroid flying around the sun.
