What happens if people breathe 15 seconds on Mars? The experience of American astronauts is the answer.

Speaking of the extraterrestrial planet that people are most interested in at present, Mars deserves it. No matter the perseverance of Americans, the landing of China's Tian Wen-1 on Mars, or the Mars immigration plan put forward by Musk, all fully expressed the human enthusiasm for Mars. So, among so many planets in the solar system, why do humans only like Mars so much? Is there anything special about Mars?

In the solar system, Mars is the second asteroid after Mercury. The shortest distance from Mars to the Earth is 56 million kilometers, and the longest distance is 320 million kilometers. The reason why humans are so interested in Mars is mainly because scientists have found through observation data that both Mars and the Earth belong to livable planets in the solar system. A long time ago, the position of Mars was better than that of the Earth, and its rotation period and mineral resources were very similar to that of the Earth. In addition, Mars has an atmosphere and water sources. Although the atmosphere of Mars is thin, it also provides conditions for life, so Mars is still very worthy of human development and exploration.

As early as 1965, Mariner 4 successfully flew over Mars and photographed the surface of Mars. According to the photos sent back by Mariner 4, we can see that most of the environment on Mars is desolate, and some places are still dry and the temperature is still very high. However, scientists have a surprise discovery on Mars, that is, Mars and the earth have very similar desert Gobi landforms. Perhaps the environment of Mars was a very livable planet like the earth a long time ago, and later it became a desolate scene for some reason.

There is also a very important reason for people's persistence in Mars, that is, they want to regard Mars as a planet of human migration, because there are too many similarities between Mars and the Earth. The atmosphere of Mars is very thin, with 98% carbon dioxide and only 0. 15% oxygen. So it is very difficult for human beings to breathe directly on Mars. What will happen if humans breathe on Mars for 15 seconds?

American scientists have also done experiments on breathing on Mars. They have simulated the atmospheric environment of Mars in the laboratory, and specially invited some astronauts to participate in this experiment. During the experiment, astronauts face temporary pressure loss. Soon after they stuck out their tongues, the saliva on their tongues began to boil and then they fainted. Because the temperature of Mars is higher than that of the earth, its boiling point and melting point are different from that of the earth, and the boiling point of Mars may become lower, which also shows that if human beings breathe in the atmosphere of Mars, it is likely to make saliva boil instantly and make people die quickly.

Through the above environment, it shows that the Martian environment still cannot allow human beings to live directly, and it needs to be reformed, such as changing the atmospheric structure of Mars. At the same time, human beings have to adapt to the gravity of Mars, which is smaller than that of the earth. It will take some time for human beings to adapt to gravity. However, Mars has always been a mystery to human beings. With the progress of human science and technology, the mystery of Mars will be slowly uncovered by human beings. In a few decades or hundreds of years, maybe Mars immigration is no longer a dream, and it is likely to become a reality. By then, humans will travel back and forth between the earth and Mars.
