The photo was sent back 55 million kilometers away. Scientist:Mars is full of ice here, with a thickness of nearly 2 kilometers.
With the increasing population of the earth and the continuous development of society, our demand for resources is increasing. Coupled with the rapid development of society, it also has some impact on the global environment. Therefore, how to properly handle the relationship between development and resources, environment and other factors may affect the sustainable development of our future civilized society. If, in the future, there are some important resource shortages on our planet, the development of our civilized society may be restricted. Since our earth has limited resources, and there are so many planets like the earth in the universe, can we develop the resources we need from other planets, or emigrate to other planets to ease the pressure on the earth? In theory, it should be feasible.
Mars, a planet in our solar system that is livable There are many similarities between Mars in the zone, so there are some opinions that if we transform Mars, Mars should have the potential to become our human”second home”. Judging from the current situation, more and more space agencies are participating in the exploration of Mars. This year, three Mars probes are expected to go to Mars. In the future, we humans also plan to send astronauts to Mars, even on Mars. Build a Martian city above to prepare for immigration to Mars.
Although Mars and the earth are in the habitable zone of the solar system, The environment between the two is still very different. Our planet has a suitable temperature and a dense atmosphere, liquid water can exist, and the environment of Mars is very arid, just like the desert area of our planet. If we humans land on Mars, the first problem is to solve the water problem. For our lives, water is very important. It is not an exaggeration to call it the”source of life”. If Mars is very close to our earth, we can transport water resources from the earth to Mars at any time, the problem is still solved. However, due to issues such as the distance and orbit between the Earth and Mars, the launch window of the Mars rover will only be available approximately every 26 months, meaning that we cannot supply water to the “residents” who land on Mars in real time. The ideal method is to achieve self-sufficiency in water resources on Mars. The question is, is there water on Mars?
Previous Mars probes have found that Mars is extremely dry, But there is still water ice material. According to a Russian scientific report on July 3, 2020, the European Space Agency (ESA) released a video clip of Mars photos sent back from the Mars Express orbiter. In other words, this video shows us the scene above Mars. Unlike previous Mars photos, this time the photo shows us the picture of the Korolev Crater, 82 kilometers in diameter near the north pole of Mars.
Scientists say that this crater has a long history, about 40 It appeared a hundred million years ago. In previous studies, the Mars environment was billions of years ago, and there was liquid water, so water also existed in these craters. Although the overall environment of Mars has become very dry, there are still many water ice materials in the craters in these polar regions. In this Korolev crater, the area is now full of ice. In the coldest time, the thickness of these ices can be close to 2 kilometers. This is enough to show that Mars still has water, and the water content should meet the long-term survival needs of some humans on Mars.
From a long-term perspective, the future manned landing on Mars 1. Immigration to Mars may become a trend in the future. Of course, Mars is not our ideal second home, and immigration to Mars will also face many problems. However, with the continuous development of our human science and technology, we humans may go to the farther deep space of the universe in the future and land on other habitable planets outside the solar system. This process is a gradual process, from the moon 380,000 kilometers away to Mars 55 million kilometers away, and may eventually leave the solar system. This may seem incredible, but it is indeed possible. Just like people 100 years ago, it is difficult to imagine that we can reach an alien planet now, and it is difficult to imagine that we can communicate with friends around the world in real time with a mobile phone. This is the power of technology.
