Snowy Owl clapped vigorously when he heard someone follow his train of thought and say what he wanted to say.

"Yes, that's what you said. The source of the water source is not likely to change much in a while, but after the water flows out, we should go and see what changes will happen to the water.

When we have finished recording the changes in the way the water flows out, and then return to the source of the water to stare at it, we can also have a deeper understanding of Mars! "

After Snowy Owl finished telling a few people, the aerospace plane started up and flew out in the direction of the water flow.

They took a picture of the plane, the state of the water flowing below it, and related things with high-definition cameras.

Since the aerospace plane mainly observes the dynamics below, it does not fly very fast, and the water flow below is no different.

If there is any difference, it is that after the water flows over the surface of Mars, it takes away part of the soil that flows through the land. The soil is washed down by the water flow and mixed in the water flow.

Originally, when the water came out of the water source, there were no other impurities, and the water was very clear, but as the water continued to flow, the water that took away a large amount of soil appeared in color.

From the original clear, transparent and colorless water, it turned into a muddy, gravel-filled reddish-brown water flow, the color of which was particularly similar to the color of mountain floods on the earth.

The aerospace plane is still flying forward, and a large amount of water is still flowing, and it is still scouring the soil on the surface of Mars.

The plane flew forward again for a certain distance, and the speed of the water flow finally slowed down, and not only the flow slowed down, but the water flow rate was also small. This is also because the surface of Mars is too dry, and a large part of the water flow It has been absorbed by the surface of Mars.

Therefore, after they flew for a certain distance, the impact of the water flow became smaller, and the water flow also became smaller.

The plane continued to fly in the direction of the water flow, and the water flow did not flow very far, so they flew the plane, and it didn't take long for them to come to the end of the water flow.

At this time, the water flow under Snowy Owl's fuselage no longer had the impact at the source. Although it was still flowing forward, the current flow was just like the forest stream on the earth.

There was no such momentum as before, and a gurgling brook appeared below them.

It is also because there is no impact force that all kinds of gravel and mud washed down from the upstream are also left on the way of water flow.So the babbling brook below them became clear again.

At this moment, the plane stopped here, and Snowy Owl and the others planned to carry out landing activities here, because this is the most suitable place to take water samples, and there is really no better place than this.

Snowy Owl took one person and got ready on the plane. After the two of them were ready, the aerospace plane landed on the surface of Mars again at the hovering position.

After getting fully prepared, Snowy Owl and an opponent immediately got off the plane, took all the tools on their bodies, and came directly to the edge of the creek.

Then came the sampling. At this moment, the sampling process they carried out was extremely strict, and they were afraid that the samples obtained would be unqualified, which would affect their future research.

When the snowy owl came to the still flowing water, it did not collect samples immediately, but took out the temperature measurement first.

After taking it out, I first measured the temperature of Mars at this moment and here, and then inserted the thermometer into the creek in front of me.

As soon as the temperature of the water was measured, the snowy owl felt astonished for a while, and then figured out why.

After collecting all the data obtained here, after all this last night, the snowy owl took out the sampling device and started sampling.

And this time, the sampling is not just a little, but a lot, including the ones that will be brought back to the earth, and the ones that will be tested on the plane next.

The water sample was taken very smoothly, and the snowy owls returned to the plane immediately after the sampling was completed.

As soon as it returned to the plane, the plane left the surface of Mars again and hovered over the original place.

And the astronauts in the plane, what are you doing now?They are all in the laboratory on the plane, and they are analyzing the water composition of the water that has just been sampled.

The instruments were running on the plane, but the mission they had come this time was still not completed, Snowy Owl and the others flew towards the direction of the water flow again.

The plane didn't fly forward for long, and soon they came to the end of the water flow.

The water finally began to gather here, and never continued to flow forward. It stopped at this low-lying place, and as the water pooled more and more, it finally converged into a small lake.

Moreover, this small lake has obvious freezing phenomenon, and the water at the bottom of the lake that stopped flowing first has already solidified into ice.

Now the bottom of this lake is ice, and the upper layer is water, and the water that flows here is slowly turning into ice.

According to the speculation of the astronauts on the plane, as long as there is no new water flow here, it will not take long for this small lake to become a solid ice lump, and the entire small lake will be frozen into a whole.

After collecting the situation at the source of the water flow, the aerospace plane did fly towards the source of the water flow again.

The speed of flying back was very fast, and it was also because there was no need to observe on the road. When they returned to the crater again, the water flow in the place where the water spewed had begun to decrease.

Obviously, this is because the internal pressure here has become smaller, causing the water flow in the crevice where the gushing water is to become smaller.

Snowy Owl and the others also lamented that they came back at just the right time, and they were able to collect all the details here.

For a period of time after that, they kept shooting in the sky, and the time passed unknowingly while they were shooting.

Finally, under their waiting, there was no longer any water gushing out of that gap, even small streams of water flowing out were gone.

Seeing that the water below had stopped gushing out, the astronauts on the aerospace plane got off the plane once and took strict sampling here.

After they took the samples, an astronaut came to the crater again curiously. He wanted to look inside the crater to see the current situation of the volcano.

It didn't matter if he looked at it like this, but it made him see a new situation. The inside of the crater was still emitting orange light, and there was still a lot of flowing magma inside, and occasionally a stream of magma sprayed into the air.

But now these magmas no longer exist at all. How can there be magma in the crater? At this moment, they have all turned into iron-black magma stones.

As the commander, Snowy Owl can't have him every time he leaves the warehouse, so this time he stayed on the plane on duty. After discovering the situation in the crater, although Snowy Owl didn't go to the scene, he still responded to it through video Bold guesses were made about what happened.

He also recalled the various situations he had encountered on the way to the end of the water, and the combination of all these situations really made him discover something remarkable.

Snowy Owl did not make any announcements, but was still perfecting his own theory based on the current situation.

The astronauts on the surface of Mars are still nervously collecting environmental data at this moment and there. After they have completed the collection, the astronauts who are out of the warehouse will start chirping and discussing as soon as they return to the plane.

The content of the discussion is also all related to the wonders that happened before Mars. When the voice of all discussions became smaller and smaller, the team members discovered that when they were discussing just now, Commander Snow Owl had a little opinion. None involved.

After the astronauts collected the data near the crater again, the aerospace plane was once again suspended in the air not far from here.

Looking at the team members who had calmed down at this moment, Xue Ou didn't do anything mysterious for any reason, and simply told everyone his guess.

"I don't know if you have noticed, but this volcanic eruption on Mars is very special, it is extremely special."

Everyone was a little confused, why Snowy Owl would say that, there is a volcanic eruption on Mars, capital and profit is a special thing, but I don't know why he would say that!
The team members turned to Snowy Owl with doubts on their faces, wanting to hear what he wanted to express.

"First of all, let me say something first, that is, this volcano is not the first eruption, nor is it the last eruption, but it has erupted for an unknown number of times."

Everyone was trying to understand what he said, but there was too little information revealed in Snowy Owl's words, so they didn't know how to understand it, and they didn't know what Snowy Owl wanted to express.

Everyone just waited to continue to look at Snowy Owl with doubtful eyes, and listened quietly to his continuation.

"This first point, everyone, remember it first, and everyone will understand when I finish all the explanation.

You might as well look at this Martian volcanic eruption comprehensively. Let us take the volcanic eruption, magma outflow, local temperature rise, humidity increase, a large amount of water spewing out from the hillside near the volcano, and the large amount of water after that to form a mountain torrent, and finally flow all the way. Finally reached the lake, where the water was finally frozen into ice lumps.

All of this is connected in series, what can you think of? "

Snowy Owl has already made it very clear at this time, but he only said half of what he wanted to express, but the team members still haven't figured it out.

"Comrades, it is a cycle, what I want to talk about is a cycle, and this should form a perfect closed loop!

The interior of Mars continues to accumulate energy, which eventually causes volcanic eruptions. After the volcanic eruptions, the temperature here will rise, whether it is the surface temperature or the underground temperature.

What does this increase in temperature cause?It will cause the temperature of a large amount of underground solid water and liquid water near the volcano to rise accordingly. When the water temperature is too high and boils, the internal pressure will increase, and whoever will be ejected from the weak part of the earth's crust. "

At this point, Snowy Owl stopped after hearing this. Although everyone had already understood these things more or less before, he still gave the team members a time to digest.

After waiting for a few minutes, he also took the opportunity to take a sip of water, and after everyone turned their attention to him again, he also started talking again.

"Everyone should know about these, so I will continue to talk about my new guess, that is, after the water was sprayed out, the groundwater found an outlet, and the water from other places was also converging towards this place.

The volcano is constantly heating the nearby water, and the heated water is constantly spraying out. As the temperature of the volcano continues to heat the water, the temperature of the volcano continues to drop.

In the end, the temperature of the volcano was cooled by a large amount of water, and the volcano returned to calm again, and because the water has no heat, the groundwater no longer boils and there is no huge pressure, so it no longer spews out!
This volcano has completed a cycle, a cycle from eruption to cooling, so everyone should understand what I want to talk about! "

After listening to his narration, everyone was shocked by his guess. After thinking about it, it seemed that the previous volcanic eruption was such a set of procedures, and the more they thought about it, the more it seemed like a fact.

"Head, I understand what you mean by cycle, but why do you say this is not the first time? I don't understand this!"

Hearing this question, Snowy Owl immediately began to answer their questions, and of course he was talking about his speculation.

"This question is actually very easy to understand. Everyone should know that at the end of the water flow, there is a huge pit, but at this moment it has become a lake, or a huge ice lump.

Think back carefully, everyone, I wonder if you found anything along the way we followed the current. "

Under his guidance, all the team members were following his train of thought. One of the players who reacted quickly answered after thinking about it.

"What the head said is that the direction of water flow is specific, and there is a fixed channel. Since the water flows in a fixed channel, it proves that this water must not flow through here for the first time. I don't know how many times I have passed through the mountain torrents before I was hit by the water.

I'm right, I feel that my understanding should be in place! "

After hearing this answer, Snow Owl immediately cast admiring glances at the man.

"Yes, I just want to explain this, so I said that this volcano is not the first eruption, nor will it be the cause of the last eruption! I don't know what everyone thinks of my guess!"

At this moment, after listening to Snowy Owl's narration, everyone suddenly realized that what they said before was all speculation.

Almost all the team members who have finished listening have already regarded what Xue Ou just said as a fact.

Everyone was admiring at the moment. Looking at the snowy owl, they realized that what the snowy owl said should be true.

Just after all the team members figured out the speculation, one of the team members had doubts again, and immediately asked his question.

"Head, I already understood the question just now, but there is still one thing I don't understand, and that is..."
