Chapter 998

Now, standing at the foot of Olympus, he looked up at the mountain which seemed to pierce the sky. If his eyesight was not good enough, he might not be able to see the top of the mountain clearly. No wonder he was shocked.

Because the Olympus mountain is the largest known volcano in the solar system. It is about 600 kilometers wide and the height difference from the foot of the mountain to the top of the mountain is 21.9 kilometers. What is this concept?

The most famous Mount Qomolangma on the earth is only 8844.43 meters high. That is to say, the height of Mount Olympus is about the height of two and a half Mount Qomolangma stacked together. If it were on earth, the peaks would be in the clouds!

But even on Mars, where the atmosphere is very thin, it's hard to see its summit if you can't see it, although the slope of the whole volcano is very gentle (about 1-2.5 degrees near the top and about 5 degrees outside).

But its huge width and height make it impossible to see the full picture from the surface of Mars, for example, the top of the mountain cannot be seen from the edge of the mountain, and the edge of the mountain cannot be seen from the top of the mountain. In fact, there are other large volcanoes on Mars.

Lei Tiantang also wanted to have a panoramic view of it from a higher angle, so he took off in the air, and in just two seconds he flew to a place about 500 high above the peak of Mount Olympus.

From this point of view, this volcano is also a very shocking picture, the creation of nature is really not good!

According to the data he saw before, it can be clearly seen that the crater is composed of six mutual covering subsides, which are about 80 km long and 60 km wide, and the crater wall can be as high as 3.2 km. For other volcanic cliffs up to 8 kilometers, this is a rare volcanic cliff.

"Kuafu, did you say that the formation of these volcanoes on Mars happened to be the time when Martian life was destroyed? More than 3 billion years ago, Mars, which was originally full of vitality, was hit by one or more meteorites with very large volume and mass, and the whole Mars was directly destroyed.

It's as if all of Mars's internal lava gushed out from the other side of the impact and formed these tall volcanoes, and it was this impact that destroyed the entire core of Mars, leading to the disappearance of the magnetic field that protected the entire planet.

This is the reason for the extinction of Martian life Staring at the two craters on the crater, Lei Tiantang told Kuafu his guess.

"Maybe, this should be a reliable guess. After all, according to the exploration data, Mars was hit about 1 billion years after the formation of the solar system. At that time, although the solar system had formed a relatively stable celestial system, there were still a large number of asteroids at that time.

In particular, Mars is too close to Jupiter. Those asteroids are easily affected by Jupiter's gravity, so they can change their flight path and collide with Mars. Even the formation of asteroid belt has something to do with this. It is normal for them to be impacted.

The specific situation will wait for our detection results. I believe that the satellite probe and landing exploration launched by us this time can have an interesting harvest, and then we can prove whether this is the reason! " Kuafu also agrees with this conjecture in the communication system.

Of course, it is not that they have such a conjecture, and scientists have not made such a conjecture, but the previous research is also based on the simulation calculation, and the real evidence will be proved after the large-scale field exploration of Mars.

"Yes! I'd better get down to business! Let's see if there is any liquid water in the speculation here! " Lei Tiantang nodded and said.

Anyway, he looked at the scenery, that is, to see something fresh. He could not even remember how many stars and planets had been swallowed by the small black hole itself. What kind of strange scenery had not been seen? So he was surprised. He didn't forget what he wanted to do this time.

So he began to circle Mount Olympus and began to make a detailed survey of it as he descended. When he detected the bottom of the mountain in the west, he finally made an amazing discovery!

He found an underground lake about 700 meters from the surface of Mars! It was in a lava passage. It was a closed space. The area of the underground lake was not very large. It was about 30000 square meters. The deepest place was about 29 meters.

But this discovery is enough to surprise Lei Tiantang. He contacted Kuafu as soon as he found out here.

"Ha ha! Sometimes I feel like I'm God's favorite son! I can't believe it was discovered so soon!

You hurry to prepare the laboratory on the spaceship. I will take the water collected from this underground lake to carry out the experiment. Maybe we can find evidence of life in it! "

"Bullshit! That's the possibility that there is an underground lake after we use scientific and technological means to calculate and guess there is an underground lake. Will you do such a detailed inspection after that? Or you'll have to go through the whole Mars on your own and see how long it will take you to find it!Come back as soon as you get the samples. I have already sorted out the samples in the laboratory. I was going to analyze the samples I just collected. Now it seems that it is more reliable to analyze your samples first! " Kua Fu does not make complaints about face.

Because it has just dug out some ice and some rocks from the ground near the spaceship for analysis in the laboratory. Of course, he has reasons to be upset about doing wedding clothes for others at the beginning of the experiment, even if the person is his own boss.

"Go away! What samples do you have that matter to me? Wait, I'll be right back! " Lei Tian Tang laughs and scolds.

In fact, Lei Tiantang has initially used his own ability to detect the whole underground lake. There is no life that conforms to the standard life form. He has not sensed the life, whether it is a larger life or a life like bacteria.

However, he is also the first time to do such a thing. He is not sure that there is no life in the lake that he has never seen. So he still takes some samples back to the spacecraft and tests them with the laboratory equipment on the spacecraft.

Maybe a new life form can be discovered? So Lei Tiantang collected a total of 2000 lake water samples from various parts of the underground lake, and prepared to take them back for careful investigation.
