"The next stop on Mars" Humans step into the sea of stars, and Mars is the next stop.

Tian Wen-1, which was launched to Mars, completed the established scientific exploration mission and sent back a large number of images of Mars. The unique landform of Mars crater photographed by Zhu Rong of the Mars rover helps people to know more about Mars.

What is Mars like? Will this huge red planet become a new home for mankind? Man is full of curiosity about Mars.

Recently, I read a popular science book about Mars. The next stop of Mars made me "walk into" Mars and learn about this mysterious planet. The book consists of nine chapters, which introduces Mars from the past to the future in a timeline, giving me a comprehensive understanding of Mars.

Author Mao Xinyuan is a doctor of space engineering and an expert in space science popularization. From doctor of space flight to master of popular science, he used his influence to make more and more people pay attention to China space flight.

In ancient China, there were special officials who were responsible for observing the celestial phenomena, and almost every dynasty had a stargazing platform. In ancient times when science and technology were underdeveloped, Mars was considered as "glowing like fire" and was called "glowing".

The appearance of Mars is regarded as an ominous thing and a symbol of various disasters such as war, flood and plague. The ancients in China discovered that Mars was retrograde and called it "Mars stays in Antares". If this phenomenon is observed, it is considered that the royal family is facing a major threat.

In eastern culture, Mars is an ominous symbol, and there is not much difference between Chinese and western perceptions of Mars: the color is slightly orange-red, and the trajectory is uncertain and unpredictable.

In the ancient Egyptian civilization and the two river valley civilization, Mars was given the symbolic meaning of death, war and disaster.

With the progress of science and technology, the appearance of astronomical telescope makes people realize the vastness of the universe, people have a gradual understanding of Mars, and their cognition of Mars has also changed. "Mars retrograde" is just a normal astronomical phenomenon.

About Mars: It takes 365 days for the earth to go around the sun, and Mars flies slowly, so it takes 687 days to go around the sun. The atmosphere of Mars is very thin. Without sunlight, the surface temperature of Mars dropped sharply from 35 degrees to minus 100 degrees Celsius. Without the protection of spacesuits, human beings can't survive at all. Mars is small. If the earth is tennis, Mars is only as big as table tennis. ......

Humans are curious about the unknown world, and the Apollo moon landing program successfully landed on the surface of the moon. Today in 2 1 century, mankind has ushered in the era of Mars exploration.

The American Mars probe Odyssey has been working for 18 years. In addition, the European Space Agency's Mars Express, Mars Bioexploration Program and Indian Mars probe Man Garian have also been launched.

So far, the success rate of all mission to mars is less than 50%. On July 23rd, 2020, Tian Wen-1 Mars probe was successfully launched from Wenchang Satellite Launch Center in China, which opened the way for China to explore Mars.

In this era of Mars exploration, the scientific progress in the new century has gradually realized the dream of Mars exploration in many countries, and the activities of Mars exploration have become more and more abundant. It seems that going out of the earth is the only way for us to grow up.

Since the 20th century, the United States, Russia, the European Union, India and China have all tried to explore Mars, and the development of Mars has also entered the important agenda of national space development plans.

Today, the history of human exploration of Mars has been nearly 60 years. Mars itself is small in size and mass. There are various chlorides in Martian soil, which need to be treated before they can be used in agriculture. Fortunately, it contains silicate and trace elements, which are the basic components of the earth's soil.

In the future, the earth will be destroyed one day. Nowadays, natural disasters such as climate anomalies, earthquakes, volcanic eruptions and tsunamis occur frequently, which bring great loads to the earth. In addition, the man-made destruction of the environment has also prompted mankind to speed up the exploration of space and find a second planet suitable for human habitation in the universe.

Mars immigrants will inherit the human genes of the earth and be more capable of coping with the environment with high radiation and high pollution. Physical development, education and medical care will also be very different. Living in a harsh base environment, everyone should receive an elite education. Mars immigrants will have far more per capita resources than the earth, and there will be no obvious uneven distribution and gap between the rich and the poor.

There is still a long way to go before humans land on Mars and truly immigrate to Mars. The future is expected.
