The Zheng He had already started to decelerate when it was still a day away from Mars. The acceleration relies on a powerful nuclear fusion engine, and the deceleration still relies on the traditional plasma engine. Naturally, it must be much earlier to reduce the speed enough. The extent to which it is captured by the gravitational pull of Mars.

DiDi~~ Although there is still a day's journey to Mars, the scientists led by Jiang Zhipeng have already started 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 are on Earth, scientists can measure distant celestial bodies based on astronomical telescopes and other instruments, and the data is very accurate. The scientists of Qingquan Technology are so close to Mars, naturally there is no problem at all, and More precise data can also be obtained.

Mars, the mass is 6.4219×10??kg, which is about 1/10 of the earth and 9 times that of the moon (this place can reflect the importance of the moon to human beings, and the planet closest to you is only 9 times heavier than the moon) Only), the diameter is half the Earth's, the volume is only 15% of the Earth's, and the surface area is only the size of the Earth's land area.

The surface gravity is about 2.5 times that of the moon and 2/5 of that of the earth, which means that ants that weigh 2 pounds can be lifted on the earth, and objects that weigh 5 pounds can be lifted on Mars (well, ants can lift that heavy Something? Author fungus).

The autobiographical period is 24.6229 hours, and the Earth's is 23 hours, 56 minutes and 3 seconds, which means that a day on Mars is more than half an hour in 24 hours; the revolution period is 687 days, and the revolution period of the Earth is 365.24219 days, which means that a year of Mars The time is 687 days, the Earth people are about to spend 2 years, and the Martian talents are just over a year.

Compared with the Earth, which has only one younger brother, the Moon, Mars has two satellites, Phobos and Deimos. However, the quality of the younger brother is not at the same level at all. There are quite a few satellites on Mars, which can only be regarded as large meteorites. The shape is still very irregular, not even a ball, really not even a ball, the mass of the two satellites is not enough to form enough gravity to shape their own image, and it is not the same as our moon. grade.

Mars' orbit is elliptical, so the temperature difference between perihelion and aphelion is nearly 160 degrees Celsius where it receives sunlight. This 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 daytime. That is to say, most of the time here is colder than the north and south poles, which are the coldest on the earth. The coldest time is even minus 133 degrees, and the hottest time is only 27 degrees. The temperature difference changes greatly. Frozen, let alone humans, it's too cold here, let's go back to Earth!

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

The earth's atmosphere is mainly composed of nitrogen, accounting for 78.1%; oxygen, 20.9%; argon, 0.93%; and a small amount of carbon dioxide and rare gases (helium, neon, argon, krypton, xenon, radon) and water vapor.

In comparison, we found that the content of carbon dioxide in the atmosphere of Mars is too high, and the oxygen content is almost negligible. The rare gas is not much different, and it is not suitable for the survival of earth people at all. The atmosphere is small and the oxygen content is too low!

...

Can this place really be transformed into a place suitable for human habitation? It is simply impossible! Faced with such harsh conditions, even the all-powerful scientists shook their heads. It was too difficult!

It's interesting if it's difficult, we scientists just want to accomplish those impossible things! Jiang Zhipeng quickly cheered everyone up when he saw where the other scientists were shaking their heads.

Jiang Gong, everything else on Mars is okay. It's the atmosphere and water. I think it's the biggest test. If the temperature is low, we test by setting up reflectors in space to increase the light and increase the temperature, but the water and the atmosphere~ Speaking of this The name of the scientist is Ying Baibai, a very interesting name. It is a scientist who specializes in researching and searching for life in the universe.

Don't worry, let's take a look at the south pole of Mars. The reflectivity here is very high. Maybe it is as estimated by American scientists. There is really solid carbon dioxide here, and maybe there will be water in its deep layers. , and let's look at the traces left by those ancient lakes and rivers on Mars, I think it is very likely that there is water on Mars! Compared with other people, Jiang Zhipeng is more confident.

The temperature is so low, even if there is liquid, it is not necessarily water! Ying Baibai still shook his head and objected to Jiang Zhipeng's optimism. That's how scientists are. I don't care who you are, as long as you can't convince me, take no I dare to oppose you if you come out with real evidence.

Whether there is water, I won't know tomorrow, I'll find out when I go directly to Mars to get some samples and come back! Jiang Zhipeng talked and smiled.

As it gets closer and closer to Mars, the data obtained by scientists are constantly being revised. The red Mars is slowly enlarged. Because of the thin atmosphere, the surface of Mars can be clearly observed from the space of Mars. The whole planet is red and yellow.

Mars is basically a desert planet, with sand dunes and gravel all over the surface. The geological activity on Mars is relatively inactive. Most of the surface landforms were formed in ancient times when they were 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: ancient, crater-filled highlands in the south and younger plains in the north, with stark differences.

At the same time, as we saw earlier, there is a thick layer of polar caps on the north and south poles of Mars. As for the composition, scientists have completely determined that it is dry ice and water!

Mars really has water! After it was confirmed, many scientists were ecstatic, and the question that has puzzled earth scientists for hundreds of years has finally been answered accurately.

You must know that since the last century, when human eyes shifted from the earth to the interstellar universe, Mars has always been a planet that human beings imagined in the future suitable for future immigration, and the debate on whether there is water on Mars has always plagued people on Earth. Scientists, countries such as the United States and the former Soviet Union have even sent many probes to Mars.

But limited to technology and long distance issues, the question of whether Mars has water has not been accurately answered.

Now, Qingquan Technology scientists who have reached the orbit of Mars can finally confirm that the polar caps covered by the north and south poles of Mars really contain water, and the water content should not be too small.

There is really water! Liu Qingquan, who also received accurate information, also showed a smile on his face. For transforming the planet for immigration, the real and most urgent need is water! As long as there is water, other conditions can be transformed by scientific means, but if there is no water, everything is in vain!

You can't say that water is transported from the earth. You must know that even with the huge volume of the Zheng He, it can't transport much water at a time, and this water is even more insignificant for a planet.

If all the ice on Mars melts, it can increase the density of the current Martian atmosphere by 20 times, which is 20% of the density of the Earth's atmosphere, and at the same time, it can obtain about 10,000 cubic kilometers of water, which is only 10% of the Earth's fresh water resources. /35, 1/130,000 of the earth's water resources!

Ying Baibai frowned and calculated the water resources on Mars. There is water on Mars, but this water is too little! Only 1/35 of the earth's fresh water resources and 1/30,000 of the earth's water resources, too little!

With such a small amount of water resources, apart from all kinds of unusable ones that are distributed into the air, there will be less water that can be used by humans!

There is water in water, but this amount is too small, which makes the scientists who have just been happy for a long time shake their heads again!

On the contrary, the density of the atmosphere can be increased by 20 times, which is very good! You must know that the ice here is basically composed of dry ice and water. After melting them, carbon dioxide can rise into the atmosphere, increasing the density of the atmosphere, and carbon dioxide is a greenhouse gas, which is very helpful for raising the temperature of Mars.

Jiang Gong, this water is too little! Not enough mud! The carbon dioxide content of the polar caps at the north and south poles of Mars is too high, and the water content is too little! Ying Baibai smiled helplessly and said, what he said was muddy It refers to the evaporation of water that falls on Mars in the form of precipitation.

Things have to be looked at from two sides. Can't the density of the atmosphere be increased, and it's all greenhouse gases. Isn't it very helpful to increase the temperature of Mars!

Compared with other people's disappointment, Jiang Zhipeng was very happy. Although the water content of Mars is low, there is still water, and the transformation of the atmosphere has already been done.

Unless there is a lot of water underground on Mars, the water found on Mars is not enough to transform Mars into a planet suitable for human habitation! Ying Baibai shook his head and expressed his inference.

If Mars is to be transformed into a planet suitable for human habitation, it needs at least to cover the plains in the northern hemisphere of Mars, which requires at least 30 times as much water resources as it is now. It's enough to move in!

Don't worry, there will be bread, houses, and water! Jiang Zhipeng said in agreement that a lot of water has been found on Mars, so scientists estimate that the moons of Jupiter contain a lot of water. Most likely nothing can go wrong! (To be continued.)
