Somewhere in the void of the solar system, a huge planet is constantly moving around the sun as it has for a long time in the past. However, unlike most planets in the solar system, the autobiographical direction of this planet is actually from east to west.
, diametrically opposite to the Earth, on Mars, the sun rises in the west and sets in the east.
Mars is slowly advancing along its own orbit, and the "Kuafu" spacecraft is getting closer and closer to Mars. When it is about 2 days away from Mars, the spacecraft begins to continuously slow down so that it can be caught by Mars when it arrives.
Gravity capture.
"Didi~~"
Although there is still one day's journey from Mars, the scientists on the spacecraft have begun to work in an all-round way. All the instruments are turned on, and all the data about Mars will be obtained soon.
When they were on the earth, scientists could measure distant celestial bodies using various instruments such as astronomical telescopes, and the data was very accurate. Now that scientists are so close to Mars, there is naturally no problem at all, and it is still
More accurate data can be obtained.
Mars has a mass of 6.4219x1023kg, which is about 1/10 of the Earth and 9 times that of the Moon (this place can also reflect the importance of the Moon to humans, the nearest planet is only 9 times heavier than the Moon), diameter
It is half the size of the Earth, its volume is only 15% of the Earth's, and its surface area is 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 that of the earth. This means that an ant weighing 2 kilograms can be lifted on the earth, but an object weighing 5 kilograms can be lifted on Mars.
The autobiographical period is 24.6229 hours, and the earth's autobiographical period is 23 hours, 56 minutes and 3 seconds, which means that a day on Mars is half an hour more than 24 hours; the revolution period is 687 days, and the earth's revolution period is 365.24219 days, which means one year on Mars
The time is 687 days. People on Earth have almost spent 2 years, and Mars has only just started a year.
Compared with the earth, which has only one smaller brother, the moon, Mars has two satellites, Phobos and Deimos. However, the quality of the smaller satellites is not at the same level. Mars has many satellites that can only be regarded as large-sized meteorites in shape.
They are both very irregular. They are not even balls. They are not even balls. The mass of the two satellites is not enough to form enough gravity to shape their own images. They are not at the same level as our moon.
.
The orbit of Mars is elliptical, so where it receives sunlight, the temperature difference between perihelion and aphelion is nearly 160 degrees Celsius, 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 during the day in summer. This means that most of the time it is colder than the coldest North and South Pole on Earth.
It’s cold. The coldest time even reaches minus 133 degrees, and the hottest time is only 27 degrees. The temperature difference changes so much that even the penguins say they will be frozen, let alone humans. It’s too cold here. We’d better go back to Earth.
Bar.
The density of Mars' atmosphere is only about 1% of that of Earth. It is very dry and low in temperature. The average surface temperature is minus 55 degrees Celsius. Water and carbon dioxide are easy to freeze. The main components of the atmosphere are carbon dioxide (95.3%) plus nitrogen (2.7%) and argon.
(1.6%) and trace amounts of oxygen (0.15%) and water vapor (0.03%).
The main components of the earth's atmosphere are nitrogen, accounting for 78.1%; oxygen accounting for 20.9%; argon accounting for 0.93%; and a small amount of carbon dioxide, rare gases (helium, neon, argon, krypton, xenon, radon)
and water vapor.
By comparison, we found that the carbon dioxide content of Mars' atmospheric components is too high, and the oxygen content is almost negligible. The rare gases are not much different. It is not suitable for the survival of people on earth at all. There is little atmosphere and the oxygen content is too low!
…
As we get closer to Mars, the data obtained by scientists are constantly being revised. The red Mars slowly enlarges. Because of the thin atmosphere, the surface of Mars can be clearly observed from space on Mars.
The whole planet is yellow-red.
Mars is basically a desert planet, with sand dunes and gravels all over the surface. The geological activity of Mars is relatively inactive. Most of the surface landforms were formed in ancient, more active periods. There are dense craters, volcanoes and canyons, including the highest mountain in the solar system -
Mount Olympus and the largest canyon - Canyon Mariner.
Another unique topographic feature is the obvious difference between the northern and southern hemispheres. The south is ancient, cratered highlands, and the north is younger plains. The difference is very obvious.
"Could it be that all the oxygen on Mars oxidizes with iron and produces iron oxide?"
In the Kuafu spacecraft, Li Jingxuan carefully observed Mars. Through the telescope, he could clearly see bits and pieces on Mars. It was covered with gravel, indicating yellow-red gravel, sand, soil, etc. These things, at first glance,
I know it's an oxide.
"This possibility cannot be ruled out. The temperature difference on Mars is too big. When the temperature is high, the chemical reactions will be more violent. Coupled with the long years of erosion, not only oxygen, but also other gases may be hidden.
.”
"You see, the north and south poles of Mars are almost exactly the same as the ice layers at the north and south poles of our Earth. But judging from the basic composition, the ice layers at the north and south poles of Mars are not only made of water, but also a large amount of dry ice."
Liu Daoming nodded. This time, the mission of the two of them was to search for extraterrestrial life, and by the way, they also investigated whether Mars could possibly become mankind's second home.
"The water content 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, thought for a moment and said.
"The temperature at the bottom is relatively high and stable, so it is very likely that primitive life will be born."
"But our principal said that he wants to transform Mars into a planet suitable for human habitation. I think this is a bit fanciful."
"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. The cost of transformation is too high.
.”
Liu Daoming couldn't help but shake his head when he thought of what the principal told him.
"This is uncertain. There is no water on Mars and the atmosphere is very thin. However, in the solar system, there are many places with water."
“Our spacecraft has visited the asteroid belt several times to mine asteroids, and we have found that some massive asteroids contain a large amount of water. Jupiter’s moon Europa is estimated to contain more water than the water on Earth.
"
"If we can drag Europa to the fire system, we can solve the water problem, and then find some gaseous asteroids and drag these asteroids to Mars, we can solve the Martian atmosphere problem."
"As long as there is a lot of water and a thick atmosphere on Mars, its temperature can become more stable, and other things 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 Kuafu spacecraft became slower and slower. When it approached Mars, it was successfully captured by the huge gravity of Mars, and began to continuously move around Mars, temporarily becoming a satellite of Mars.
"Launching an unmanned anti-gravity spacecraft~"
"Launch an unmanned detector~"
"Launch global communication and positioning satellites on Mars~"
Wu Renjie, the captain of the Kuafu, issued orders one after another.
Soon, from the huge Kuafu spacecraft, small anti-gravity aircraft swooped down directly from space towards Mars like birds returning to their nests.
At the same time, satellites were continuously released one after another from the Kuafu spacecraft, and various detectors were spread to Mars for free.
Here at the Earth and Galaxy Science Institute, Qin Yi and many scientists also received news that the Kuafu spacecraft had arrived at Mars and that the scientific research on Mars was about to begin, so even though it was two in the morning
At this point, Qin Yi, like many scientists, came to the institute without feeling sleepy at all.
"We humans will soon take a historic step and set foot on the second planet."
Lu Qingwei, Liu Peiqiang, Wang Songling, Qiu Feng and other scientists from the Galaxy Research Institute almost all came over. For such a major event, no one wanted to miss it.
At this time, Lu Qingwei seemed very excited. Looking at the pictures sent back by the Kuafu spacecraft, the red-hot Mars seemed to have a magical power, which fascinated people.
"Wow, the hurricane on Mars is too powerful, right?"
Soon, Lu Qingwei couldn't help but screamed in surprise.
I saw in the picture sent back from Mars, on the surface of Mars, a terrifying hurricane was raging at a terrifying speed. Wherever it passed, sand and rocks were flying, and the sky was covered with dust.
It formed a situation similar to a typhoon on Earth.
"The wind force exceeds level 21~"
Liu Peiqiang was also dumbfounded. The typhoons, hurricanes and the like on the earth are only level 17 at most, with wind speeds of more than 300 kilometers per hour, but the hurricane on Mars actually exceeds level 21, which is simply beyond imagination.
"Inform Wu Renjie to pay attention to safety when landing on Mars, especially this Martian hurricane."
Qin Yi looked at the hurricane on Mars and couldn't help showing a worried look. He thought about it and gave the order.
Such a terrible hurricane, and the pattern of its appearance is currently not known. Once it appears when Mars lands, it will be quite dangerous. I remember that there was such a plot in a science fiction movie before.
