Moreover, there must be a large number of lava tunnels that have collapsed or have not collapsed.

Such a peculiar landform, such a unique volcano, and such a dense lava tunnel are the best choice for establishing a scientific research base. Moreover, according to the detection, volcanic activity inside Mount Olympus has long ceased to exist. The chances of reawakening are negligible.

It is also a very good option to enter it and build a volcanic base.

It is also close to four other huge shield volcanoes – Mount Eskrells, Mount Paphnes, Mount Alcia and Mount Abbah.

Among them, Abbard Volcano has become the largest mountain in the solar system with its width of 1,600 kilometers in diameter. The height of the Eskrels volcano reaches 18 kilometers! The height of the Alcia Mountains reaches 17.7 kilometers! Among the five giant mountains, the shortest of the five giant mountains, the Pavnes Volcano, is also more than 14 kilometers high!

Beneath such a huge volcanic complex, there must be countless lava tunnels. The Martian base is of great significance not only for studying the history of the composition and evolution of the Martian volcano itself, but also for the mysteries of the gradual silence of the lava in the interior of Mars and the fact that geological activity never occurred.

Moreover, in the future, as the Martian base matures, if you want to expand accordingly. Then, in such a place where lava tunnels are dense and the underground space is vast, it is possible to build more volcanic bases, and you can also choose the nearest address! Even, after establishing a large number of Martian bases, it is possible to directly build a Martian settlement that can accommodate tens of thousands or hundreds of thousands of people.

It's just that it's easy to defend, but it's very difficult to open up the territory and overcome obstacles. There is a way to look at the mountain and run a dead horse. Although the place where this starship landed was near the Olympus volcano, Yun Lei and the others, during the autonomous journey of the Mars rover, could even see the huge Olympus Volcano through the rover's window!

and the stars that flicker in the background of the Martian sky, and the thin and beautiful clouds.

However, the speed at which the rover runs is really heartbreaking. After two days of unhurried running, we arrived at the foot of Mount Olympus.

Yun Lei and Bai Ruyi, etc., are sighing at the alien scenery and the immensity of the great power of the heavens and the earth - according to the research and analysis of scientists, although this Olympus volcano has been silent for only a few million years, it has also been active for hundreds of millions of years. This huge mountain was finally formed after hundreds of millions of years, or even billions of years.

And some top scientists looked at the thin clouds in the Martian sky, their faces excited and solemn.

On the rover, there was a discussion: "Those clouds on the horizon are not normal!"

"Is this a sign of water?"

"If the climate of Mars is analogous to the climate of a desert on Earth, I am sure that there must be a water source nearby!"

The question of whether there is water on Mars has been debated for a long time. Because in the past, water was the source of life, and with water, it almost represented the existence of life on Mars, almost the existence of Martians on Mars, and almost the invasion of Martians on Mars......

There are countless related science fiction articles alone. However, later, as human beings gradually deepened their research on the universe, it was discovered that things like water and dihydrogen oxide were very common in the universe. Even in the distant nebula seen by the Hubble telescope, the presence of water can be determined through compositional analysis.

Moreover, after a corresponding analysis of the composition of the atmosphere of Mars, it will be found that the presence of water on Mars is simply a matter of course.

The atmosphere of a volcano, unlike that of Earth, is mostly made up of carbon dioxide. Carbon dioxide accounts for 95.32 percent of the Martian atmosphere. Of the other small gases, oxygen accounts for 0.13 percent and water vapor accounts for 0.03 percent.

Although the water vapor content is so low, it is very normal for clouds to form in the high sky of Mars in some places where the water vapor content is relatively high in the atmosphere. Yun Lei even observed that this Martian morning was occasionally accompanied by morning fog and frost!

Between heaven and earth, the natural flow of matter always has its own laws. Since these clouds on Mars can be formed, and since the water vapor in the atmosphere can exist, it means that there must be a water source on the surface or underground of Mars. Just like in the deserts of the earth.

Only where there is a water source, where the oases are, above their surface, do clouds form.

Therefore, in recent times, human beings have long stopped paying attention to whether there is water on Mars. It is certain that there is water. Instead, I wonder if there is flowing water on Mars. And the question of whether this flowing water can be used by human beings.

Now, through the field survey of Yun Lei and others, it is found that although the water vapor content on Mars is similar to the original measurement, it is like the climate in the desert of the earth, and the vast majority of places are extremely dry. The moisture content in the air is far below 0.03 percent.

However, in some places, such as the vicinity of Mount Olympus, the water vapor content is much higher than the figure of 0.03 percent. Compared with other places, it is like a billionaire with a net worth of 10 billion, compared with ordinary people with a monthly income of two or three thousand. Although the amount after the average is extremely low.

However, it does not represent anything at all.

Although it has not yet been verified, both Yunlei and those top scientists have basically determined that there is not only water near this Olympus volcano! Moreover, the amount of water is not small.

It's even very likely to be a flowing water source! It's just that no one knows exactly where it is. Even small fish can't sense it. It's as if these sources of water are cut off by something!

The exploration of Mars by Yun Lei and others was not smooth.

Although they determined that there were a large number of volcanic tunnels next to Mount Olympus through the collapsed Martian lava tunnels, as they had guessed, after a long period of weathering, these collapsed lava tunnels had already been filled and buried by the dust carried by the huge dust storms that repeatedly appeared on Mars.

Even the untouched parts of the ground were filled.

It was a lot of work to get rid of the dirt and dust deposited in these lava tunnels. Even if there is a cultivator such as Tianbi Lin, don't think about it for a few months. Moreover, even if the lava tunnel is cleared out and has collapsed, it is of little use. You can only give up.
