Vol 2 Chapter 393: ,Mars

In the void somewhere in the solar system, a huge planet and the long years in the past generally revolved around the sun, but unlike most planets in the solar system, the autobiographical direction of this planet turned from east to west On the opposite side of the planet, on Mars, the sun came out to the west and set to the east.
Mars is slowly advancing along its own orbit, and the "Kwaf" spacecraft is getting closer and closer to Mars. The spacecraft will continue to slow down in about 2 days before Mars, so that when it reaches Mars Gravitational capture.
"Didi ~~"
Although there is still a day's journey from Mars, the scientists on the spacecraft have begun to work fully, all kinds of instruments are turned on, and all data about Mars will be quickly obtained.
When on Earth, scientists can measure distant celestial bodies according to various instruments such as astronomical telescopes, and the data is very accurate. Now that scientists are so close to Mars, there is naturally no problem at all, and You can get more accurate data.
Mars has a mass of 6.4219 × 1023kg, which is about 1/10 of the earth and 9 times the moon (this place can reflect the importance of the moon to humans, and the planet nearest you is only 9 times heavier than the moon), The diameter is half of the earth, the volume is only 15% of the earth, and the surface area is the size of the earth's land area, which is 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 ants that can lift 2 pounds on earth can lift 5 pounds on Mars.
The autobiographical cycle is 24.6229 hours, and the autobiography of the earth is 23 hours, 56 minutes, and 3 seconds, which means that a day on Mars is more than 24 hours and a half; the revolution cycle is 687 days, and the revolution cycle of the earth is 365.24219 days, which means one year on Mars. The time is 687 days. Earth people are going to spend 2 years, and Mars talents are in their first year.
Compared to the Earth, which has only one younger brother, the Moon, Mars has two satellites, Phobos and Phobos, but the quality of the brothers is not at all a level. Many of Mars' satellites can only be regarded as large-scale meteorites. They are still very irregular, they ca n’t even count the ball, it ’s really not even the ball, the quality of the 2 satellites is not enough to form enough gravity to shape their own image, and it ’s not at all a level with our moon. .
Mars's orbit is elliptical, so the temperature difference between the perihelion and the distant point is nearly 160 degrees Celsius at the place where it is exposed to the sun, which has a huge impact on the climate of Mars.
The average temperature on Mars is about minus 63 degrees, but there is a huge temperature difference from minus 133 degrees in winter to nearly 27 degrees in summer during the day. In other words, most of the time here is even colder than the coldest north and south poles on the earth. The coldest temperature is even 133 degrees below zero, and the hottest time is only 27 degrees. The temperature difference varies greatly. Frozen, let alone humans, it's too cold here, let's go back to earth.
The density of Mars' atmosphere is only about 1% of that of the Earth. It is very dry, with low temperature and an average surface temperature of minus 55 ° C. Water and carbon dioxide easily freeze. The main components of the atmosphere are carbon dioxide (95.3%) plus nitrogen (2.7%), argon. Gas (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 accounts for 20.9%; argon accounts for 0.93%; and a small amount of carbon dioxide and rare gases (helium, neon, argon, krypton, xenon, krypton) And water vapor.
By comparison, we find that the content of carbon dioxide in the atmosphere of Mars is too high, and the oxygen is almost negligible. The rare gases are not much different from each other. They are not suitable for the survival of humans on earth. The atmosphere is low and the oxygen content is too low!
...
As Mars gets closer and closer, the data obtained by scientists are constantly revised. The red Mars is gradually enlarged. Because of the thin atmosphere, the surface of Mars can be clearly seen from the space of Mars. The entire planet is yellow-red.
Mars is basically a desert planet. The surface is full of sand dunes and gravel. The geological activity of Mars is relatively inactive. Most of the surface landforms were formed during ancient and active periods. There are dense craters, volcanoes and canyons, including the highest mountain in the solar system. Olympus Mountain and the largest canyon-Sailor Canyon.
Another unique topographical feature is the obvious difference between the northern and southern hemispheres. The south is an ancient, crater-filled highland, and the north is a younger plain. The difference is very obvious.
"Should the oxygen of Mars all oxidize with iron, has iron oxide been produced?"
Inside the Kuafu spacecraft, Li Jingxuan carefully observed Mars. Through the telescope, you can clearly see the bits and pieces above Mars. This is full of gravel, indicating yellow-red gravel, sand, dirt, etc. I know it's an oxide.
"Do not rule out this possibility. The temperature difference between Mars is too great. When the temperature is high, the chemical reaction is more violent at home. In addition to the long-term erosion, not only oxygen, other gases may be hidden. . "
"You see, the north and south poles of Mars are almost exactly the same as the ice layers on the north and south poles of our planet, but from a fundamental point of view, the ice layers on the north and south poles of Mars are not only composed of water, but also a large amount of dry ice."
Liu Daoming nodded. This time the two men's mission was to find extraterrestrial life. By the way, they were also investigating whether Mars might become a second home for humanity.
"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 layer. I don't know if there will be primitive life in it."
Li Jingxuan nodded and thought about it.
"The temperature of the bottom layer is relatively high and relatively stable, and it is very likely that primitive life will be born."
"But our principal said that he wanted to transform Mars into a human-friendly planet, and I think this is a bit of a fable."
"Mars has too little water, 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. . "
Liu Daoming thought of the principal's account and shook his head.
"It's possible that there is no water on Mars and the atmosphere is very thin, but in the solar system, there are more places where there is water."
"Our spacecraft has traveled to the asteroid belt several times to mine asteroids, and they have all found that some large asteroids contain a lot of water on them. Jupiter's moon Europa contains more water than Earth. "
"If we can drag Europa to the fire system, we can solve the problem of water, and then find some gaseous asteroids and drag these asteroids to Mars to solve the problem of Mars' atmosphere."
"As long as Mars has a lot of water and a thick atmosphere, its temperature can become more stable, as for other things, it can be solved."
Li Jingxuan said with a smile.
"You're right, everything is possible."
Liu Daoming nodded solemnly.
The speed of the Kuafu spacecraft is getting slower and slower. When approaching Mars, it is very smoothly captured by Mars's gravitational force and starts to continuously move around Mars, temporarily becoming a Mars satellite.
"Launching an unmanned anti-gravity spaceship ~"
"Launch the unmanned detector ~"
"Launching Mars Global Communications and Positioning Satellites ~"
Captain Wu Renjie of the Kuafu ship issued successive orders.
Soon, from the huge Kuafu spacecraft, a small anti-gravity vehicle was like a small bird that just came home, and dived directly from space toward Mars.
At the same time, satellites were continuously released from the Kuafu spacecraft, and various probes were also spread on Mars without money.
Here at the Earth Galaxy Research Institute, Qin Yi and many scientists also received the news ~ EbookFREE.me ~ I know that the Kuafu spacecraft has arrived on Mars, and the scientific research work on Mars is about to begin, so Although it was two o'clock in the morning, Qin Yi, like many scientists, came to the research institute without any drowsiness.
"We humans will soon take a historic step and set our feet on the second planet."
Almost all scientists from the Xinghe Academy of Sciences, such as Lu Qingwei, Liu Peiqiang, Wang Songling, Qiu Feng, and so on, don't want to miss such a major event.
At this moment, Lu Qingwei seemed very excited, watching the picture sent back from the spacecraft Kuafu, the red Mars seemed to have a magical power, fascinating.
"Wow, the hurricane on Mars is too powerful, right?"
Soon, Lu Qingwei called out in surprise.
I saw in the picture transmitted back from Mars, on the surface of Mars, a terrible hurricane was raging at a terrible speed. Wherever I went, I walked on the sand flying stones, and the sky was covered by the sky. A situation similar to the typhoon on the earth was formed.
"Wind power is above 21 ~"
Liu Peiqiang is also dumbfounded. Typhoons and hurricanes on the earth are at most level 17, and the wind speed is more than 300 kilometers per hour. However, the hurricane above Mars surpasses level 21, which is beyond imagination.
"Notify Wu Renjie here. When landing on Mars, pay attention to safety, especially the Martian hurricane."
Qin Yi looked at the hurricane above Mars and couldn't help showing a worried look. He thought and thought.
Such a terrible hurricane has not yet mastered the law of its appearance. Once Mars landed, it would be quite dangerous. I remember that there was such a plot in a previous science fiction movie.
