Morality of Martian immigrants

Is there a giant civilization at the entrance of a 3,500-meter-high underground city found on Mars? Objectively speaking, there may be extraterrestrial life inside the solar system and outside the Milky Way, but it can be said with certainty that humans have not found any entrance to the underground city of Mars. Moreover, judging from the position of Mars in the solar system and the current environment on the planet, it is unlikely that there will be any giant civilization on this red planet, and even whether there are traces of microorganisms needs further exploration.

Mars and Earth are both one of the eight planets in the solar system. Undeniably, there are many similarities between them, especially in geological features, such as canyons and volcanoes. With the deepening of human exploration of Mars, we know the ancient times of this planet, which may be more like our present earth. For example, traces of liquid water flow have also been found on the surface of Mars.

Mars is different from other potentially livable planets, because it is the planet that human beings are most likely to reach and live first. So, can such a planet still full of many unknowns really become the second earth? If human beings want to live on this planet, what else should they prepare besides overcoming their fear of eating insects? And what impact will human beings have on this planet when they arrive at Mars?

What are the obvious differences between the star characteristics of Mars and Earth?

As a terrestrial planet, Mars accounts for about 53% of the earth's diameter, but its mass is only about 14% of the earth's. Therefore, even if the rotation period and axis inclination of Mars are close to that of our Earth, its revolution time is still about twice as long as that of the Earth.

Although Mars also has different topography, it is the desert that occupies the absolute area advantage, showing the characteristics of strong contrast between the northern hemisphere and the southern hemisphere. The northern hemisphere is mainly composed of plains formed relatively late. And because the gravity of Mars is smaller, the mountains on this planet can grow higher, which is different from the volcanoes on the earth. Ring of fire? Volcanoes on Mars are scattered distribution points. In addition to the size and landform of the planet, there are obvious differences in atmospheric composition and temperature between Mars and the Earth. The average temperature on the surface of Mars with dry and cold climate is MINUS 55 degrees Celsius, which is enough to freeze carbon dioxide and other substances, and its atmospheric density is only about 1% of that of the earth. Inactive geological activities lead to the inability to recycle carbon dioxide on the earth, so there is no obvious greenhouse effect on Mars.

Humans live on Mars, what existing resources can be used?

As far as the existing living conditions of Mars are concerned, all the exploration work currently carried out by human beings is actually to understand how to achieve self-sufficiency in survival on this planet. And this demand becomes more urgent with the acceleration of exploration. If all resources are replenished from the earth, it will involve too high a cost. Moreover, this way of exploring directly on the planet is more conducive to determining whether human beings are really lonely beings in the universe. First of all, we need to use the existing resources of Mars, such as rocket fuel and oxygen. We can all start with carbon dioxide in the atmosphere of Mars. Secondly, the water in Martian soil, such as 5% water in the equator and 60% water in the Arctic, can be extracted by technology, and even food planting and clothing production can be realized in some areas. Silicon oxide and iron oxide, which are more common in Martian soil, can be used to make things like glass and iron.

In fact, the solar energy on Mars can also provide energy for people living on Mars, and the soil on Mars is also suitable for making bricks needed for building houses. As we all know, human beings, as carnivores, have poor acceptance of vegetarian eating habits, so insects that consume less feed and water will become the most suitable meat ingredients, which may sound disgusting to many people who don't like insects, but it is one of the difficulties that human beings must overcome in living on Mars.

What impact will human migration to Mars have on this planet?

Although there are many planets in the universe, for us on earth, Mars is the closest planet to possible alien life. All the research scientists are doing now is to realize the vision of human migration to Mars within a few decades. But we need to understand the basic fact that once we set foot on the land of Mars, it will bring pollution to the planet, and the collision between Martian creatures and life on earth may also be triggered.

If Mars is a sterile environment, then humans really don't need any moral constraints, but if Mars has its own primitive life, then human intervention may further lead to their extinction. What's more, life can exist anywhere in the universe, especially where there are basic elements such as energy, liquid water and carbon. In our solar system, Mars has such basic conditions that protozoa can thrive. Therefore, we still need to consider how to explore Mars without the risk of pollution.

Perhaps, some people think that we can ignore the risks that human beings may bring to life on Mars. However, we can't ignore whether life on Mars will have an impact on our earth environment. Therefore, we need to explore more deeply whether there is evidence of life in the past and present of Mars in the future. In short, as far as the foreseeable time is concerned, Mars can't be the second Earth, even if one day we realize a self-sufficient life on Mars. But all our exploration of Mars is of great significance, because it can not only meet our needs to set foot on other planets, but also gain a deeper understanding of the past or future of the earth through a lot of information on the planet.
