Will Mars be the future home of mankind? With so many similarities, Mars is really suitable.

Mars will become a topic that people like to discuss, because people often regard it as the first choice for space immigrants. We often see the bridge of future immigrants going to Mars in science fiction movies. Why do people regard Mars as the first choice for space immigrants? Let's take a look at its advantages and similarities with the earth!

First, the distance advantage from Mars to the Earth.

Because the Earth and Mars are constantly orbiting the sun, according to theoretical analysis, when the Earth reaches the farthest point from the sun and Mars reaches the nearest point, the distance between them is 54.6 million kilometers. However, such a short distance has not been found in human exploration. The shortest recorded distance between the two occurred in 2003, and the shortest distance between Mars and the Earth was 56 million kilometers. But because their orbits around the sun are all elliptical, when they run to both sides of the sun, the farthest distance between them is about 400 million kilometers.

2. How long does it take for the Earth to reach Mars?

According to June 5438+ 10, 2006, NASA's new vision mission launched from the earth was calculated to have a speed of 58,000 kilometers per hour. It takes only 39 days to reach Mars when the earth keeps the closest distance from Mars, and it takes 289 days to reach Mars when the earth keeps the farthest distance from Mars. The average arrival time is about 160 days. China can skillfully choose the shortest distance to launch Tian Wen-1, and it will take nearly half a year to reach Mars. May be able to meet the needs of immigrants in time.

3. What are the similarities between the Earth and Mars?

First of all, the most similar place between Mars and the Earth is that they are both in the livable zone of the solar system and close to the Earth. Secondly, through exploration and research, it is found that the revolution and rotation of Mars are the same as that of the Earth, which leads to the phenomenon of day and night rotation similar to that of the Earth. A day on Mars is 24 hours and 37 minutes, which is close to the time of the Earth. Thirdly, people standing on Mars will also see the sunrise in the east and the sunset in the west, which is similar to the earth. Another great similarity is that the orbits of Mars and Earth are very close to the inclination angles of their respective equator. The inclination of Mars is 25. 19 degrees, while the inclination of the earth is 23.5 degrees. Because of the close dip angle, the four seasons on Mars alternate, which is too similar to the Earth. No wonder Mars will become the first choice for human space immigrants.

However, the similarities between Mars and the Earth are not only the above, but also their geological environment is very similar. On Mars, the main composition of the ground is the same silicate rock composition as the earth, and Mars also has a solid rock surface. The soil on Mars is rich in minerals and various compounds, which is indispensable for the basic components of life. Mars has the same South Pole and North Pole as the Earth, which is surprisingly highly similar! Mars has the same geological and climatic environment as the earth, such as plains, deserts, mountains and canyons, as well as harsh climate such as sandstorms and tornadoes.

In addition, in other respects, Mars also has an atmosphere, but unlike the earth, the main component of the atmosphere there is carbon dioxide, but with the current technology of human beings, it can be completely overcome and oxygen can be extracted from it. If you immigrate to Mars, you can probably say to the store: "The boss gave me two bottles of delicious oxygen, haha."

In addition, the data detected by Mars Pathfinder and rover sojourner show that the ground temperature of Mars during the day is 2 1, which is very suitable for human survival, but the lowest land temperature of Mars at night can reach-100, while the lowest land temperature of the earth at night is -90. Thus, if you live on Mars, don't wander around at night, or you may become. Speaking of ice, people have found traces of liquid water flowing on Mars, and there is also a lot of ice under the ice sheets of Mars' north and south poles, so people speculate that there is water on Mars, which may have given birth to life, but the truth needs further exploration by scientists. If Mars is really suitable for human survival, it seems to fly to the ground very fast!

Mars has many attractions. For example, living on Mars for one year is 687 days on the earth, and the gravity on Mars is 2/3 smaller than that on the earth, so people will become stronger on Mars, bounce and run faster than on the earth, and feel a bit like superman.

In short, there are many places on Mars that are very similar to the Earth, which makes people daydream. Just as Mars is a spare planet specially provided for human beings, it has been waiting for people on earth to discover and explore for hundreds of millions of years. Since the 1960s, people began to explore Mars, but until now people still know little about Mars, but I believe that through the efforts of generation after generation, Mars will eventually become the second home planet of mankind.
