Somewhere in the void of the solar system, a huge planet is constantly moving around the sun for a long time in the past, but unlike most planets in the solar system, the autobiographical direction of this planet is actually from east to west, which is diametrically opposed to the earth, on Mars, the sun comes out in the west and sets in the east.

Mars is slowly moving along its own orbit, and the "Kuafu" spacecraft is getting closer and closer to Mars, and there are still about 2 days to go before Mars, and the spacecraft begins to slow down continuously in order to be captured by Martian gravity when it arrives.

"Didi~~"

Although there is still a day to go to Mars, the scientists on the spacecraft have begun to work in full swing, all kinds of instruments are turned on, and all the data about Mars will soon be available.

When on Earth, scientists can measure distant celestial bodies according to astronomical telescopes and other instruments, and the data is still very accurate.

Mars, with a mass of 6.4219×1023kg, is about 1/10 of the Earth and 9 times that of the Moon (this place can reflect the importance of the Moon to mankind, and the nearest planet to you is only 9 times heavier than the Moon), with a diameter half of the Earth, a volume of only 15% of the Earth, and a surface area of only the size of the Earth's land area, about 150 million square kilometers.

The surface gravity is about 2.5 times that of the Moon and 2/5 of the Earth, which means that the Earth can lift 2 pounds of ants, and on Mars, it can lift 5 pounds of objects.

The autobiographical period is 24.6229 hours, and the earth's autobiography is 23 hours, 56 minutes and 3 seconds, which means that the day of Mars is more than 24 hours and half an hour, and the orbital period is 687 days, and the earth's orbital period is 365.24219 days, which means that the time of a year on Mars is 687 days, and the earthlings are about to spend 2 years, and the Martians are only in their early years.

Compared to the earth has only one little brother - the moon, Mars has 2 satellites, Phobos and Deimos, but the quality of the little brother is not a level at all, there are many moons on Mars that can only be regarded as meteorites with large points, and the shape is still very irregular, not even a sphere, it is really not even a sphere, and the mass of 2 satellites is not enough to form enough gravity to shape its own image, and our moon is not at the same level at all.

The orbit of Mars is elliptical, so the temperature difference between perihelion and aphelion is almost 160 degrees Celsius in the place where the sun is exposed, which has a huge impact on the climate of Mars.

The average temperature on Mars is about minus 63 degrees, but it has a huge temperature difference from minus 133 degrees in winter to nearly 27 degrees in summer during the day. That is to say, most of the time here is colder than the coldest North and South Poles on the earth, the coldest time even reaches minus 133 degrees, and the hottest time is only 27 degrees, the temperature difference is huge, even the penguin Jun said that he will be frozen, not to mention humans, it is too cold here, let's go back to the earth.

The density of the atmosphere of Mars is only about 1% of that of the Earth, very dry, the temperature is low, the average surface temperature is minus 55 °C, water and carbon dioxide are easy to freeze, and the main components of the atmosphere are carbon dioxide (95.3%) plus nitrogen (2.7%), argon (1.6%) and trace amounts of oxygen (0.15%) and water vapor (0.03%).

The composition of the earth's atmosphere is mainly nitrogen, accounting for 78.1%; oxygen accounted for 20.9%; argon accounted for 0.93%; There are also small amounts of carbon dioxide, noble gases (helium, neon, argon, krypton, xenon, radon) and water vapor.

Compared with us, we found that the content of carbon dioxide in the atmosphere of Mars is too high, the oxygen is almost negligible, and the rare gas is not much different, which is not suitable for the survival of earthlings at all, the atmosphere is small and the oxygen content is too low!

……

As Mars gets closer and closer, the data obtained by scientists is also constantly revised, the red Mars is slowly magnified, because of the thin atmosphere, the surface of Mars can be clearly observed from the space of Mars, and the entire planet is yellow-red.

Mars is basically a desert planet, the surface of the sand dunes, gravel everywhere, Mars geological activity is relatively inactive, most of the surface landforms are formed in ancient times more active, there are dense craters, volcanoes and canyons, including the highest mountain in the solar system - Mount Olympus and the largest canyon - Mariner Canyon.

Another unique topographical feature is the stark difference between the northern and southern hemispheres, with the ancient, crater-filled highlands in the south and the younger plains in the north.

"Isn't it possible that the oxygen on Mars is oxidized with iron to produce iron oxide?"

In the Kuafu spacecraft, Li Jingxuan carefully observed Mars, and through the telescope, he could clearly see the bits and pieces on Mars, which were covered with gravel, indicating yellow-red gravel, sand, soil, etc., these things, at a glance, you can know that they are oxides.

"I don't rule out this possibility, the temperature difference on Mars is too great, when the temperature is high, the chemical reaction is more violent, coupled with the erosion of the long years, not only oxygen, but other gases may be hidden."

"You see, the north and south poles of Mars are almost exactly the same as the ice at the north and south poles of our earth, but in terms of fundamental composition, the ice at the north and south poles of Mars is not only composed of water, it also has a lot of dry ice."

Liu Daoming nodded, this time the mission of the two of them is to find extraterrestrial life, and by the way, it is also to investigate whether Mars can become a second home for human beings.

"The content of this water is too small, most of it is dry ice, this dry ice is carbon dioxide, there may be some liquid water at the bottom of the ice, and I don't know if there will be primitive life in it."

Li Jingxuan nodded, thought about it and said.

"The temperature at the bottom layer is relatively high and stable, and it is very likely that primitive life will be born."

"But our principal said that he wanted to transform Mars into a habitable planet, and I think that's a bit of a fantasy."

"There is too little water on Mars, the atmosphere is too thin, and the temperature difference is too great, for us humans, even with the assistance of technology, it is difficult for us to survive in such a world, and the price of wanting to transform is too great."

Liu Daoming couldn't help but shake his head when he thought of what the principal had explained.

"It's a matter of course, there's no water on Mars, and the atmosphere is thin, but in the solar system, there's more water."

"Our spacecraft have made several trips to the asteroid belt to mine asteroids, and they have found some massive asteroids with a lot of water on them, and Jupiter's moon Europa is estimated to contain more water than on Earth."

"If we can drag Europa to the fire system, we can solve the problem of water, and then we can find some gaseous asteroids and drag these asteroids to Mars, which can solve the problem of the Martian atmosphere."

"As long as Mars has a lot of water and a thick atmosphere, its temperature can become more stable, and as for other things, it will be easy to solve."

Li Jingxuan smiled and said.

"You're right, anything is possible."

Liu Daoming nodded solemnly and said.

The speed of the Kwafu spacecraft became slower and slower, and when it approached Mars, it was captured by the huge gravitational pull of Mars very smoothly, and began to move around Mars, temporarily becoming a satellite of Mars.

"Launch of an unmanned landing anti-gravity spacecraft~"

"Launch of unmanned probe~"

"Launch of Mars Global Communication and Positioning Satellite~"

Wu Renjie, the captain of the Kuafu, issued one order after another.

Soon, from the huge Kwafu spacecraft, small anti-gravity vehicles swooped down from space towards Mars like birds returning to their nests.

At the same time, on the Kwafu spacecraft, satellites are constantly being released, and all kinds of probes are also being sown on Mars without money.

Here at the Earth Galaxy Science Research Institute, Qin Yi and many scientists also received the news that the Kuafu spacecraft had arrived on Mars, and the scientific expedition on Mars was about to begin, so even though it was two o'clock in the morning, Qin Yi, like many scientists, did not feel the slightest sleepiness and came to the research institute.

"We humans will soon take a historic step and set our feet on a second planet."

Lu Qingwei, Liu Peiqiang, Wang Songling, Qiu Feng and other scientists from the Galaxy Science Research Institute have almost all come, and everyone does not want to miss such a big event.

At this time, Lu Qingwei looked very excited, looking at the picture sent back by the Kuafu spacecraft, the red-hot Mars seemed to have a magical power, which made people fascinated.

"Wow, there's too much of a hurricane on Mars, isn't it?"

Soon, Lu Qingwei couldn't help but cry out in surprise.

I saw that in the picture teleported back from Mars, on the surface of Mars, a terrifying hurricane was constantly raging at a terrible speed, and everywhere it passed, sand and rocks were flying, and the sand and dust covered the sky and the sun, forming a situation similar to that of a typhoon on the earth.

"Wind force over 21~"

Liu Peiqiang was also dumbfounded, the typhoons and hurricanes on the earth are at most 17, and the wind speed is already more than 300 kilometers per hour, but the hurricanes on Mars are more than 21, which is beyond imagination.

"Inform Wu Renjie's side that you must pay attention to safety when landing on Mars, especially this Martian hurricane."

Qin Yi looked at the hurricane on Mars, and couldn't help but show a worried look, and after thinking about it, he also commanded.

Such a terrible hurricane, and there is no law of its appearance at present, once it appears when Mars lands, it will be quite dangerous, I remember that there was such a plot in a previous science fiction movie.
