Just seconds after Voyager answered, the screen lit up, and the camera showed a scene near the probe's landing site. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

What appears on the screen is an ordinary plain, where there is no grass and only a few inconspicuous pebbles scattered there. These stones may have a lifespan longer than human history, but, unlike energetic humans, these stones can only lie on the ground and cannot create a splendid culture.

Seeing such a desolate scene, Spred spoke: "It seems that there really can't be life on this planet. There was a deep disappointment in his tone.

"We can't expect life to occur on every planet that is located within the habitable zone." Zhou Xin comforted, "After all, the conditions for life to appear are too harsh, and any difference will lead to the inability of life to be produced. ”

"Although I understand that." Spred's tone returned, "But I still feel a little-"

"Alright, don't worry about that." Zhou Xin said, "Let's take a look at this planet." ”

As he spoke, the probe had already begun to move on the planet, and after walking a few meters forward, a shallow crater appeared on the screen, judging by the size of the crater, which should be the last place where the probe bounced. Carefully circumventing the crater, the probe continued its progress, and after advancing more than ten meters, a crater appeared again in front of it, this one a little larger and deeper than the previous one. Moving forward, the probe encountered a total of six craters over the next few hundred meters. These craters went from shallow to deep, from small to large, and when they arrived at the first landing site of the probe, Zhou Xin saw a large crater with a diameter of nearly 30 meters and a depth of more than one meter. Zhou Xin saw that the dust raised by the probe when it landed had fallen back to the ground, making the pit look like a small crater. Judging from the environment of this planet, this small crater will remain on the planet for a long time, and it will not change for thousands of years.

Along the way, Zhou Xin didn't see anything noteworthy in the field of vision of the probe, and he also found a very strange thing is that the surface of this planet seems to be very soft, and the probe left a deep imprint on the ground when it advances, I don't know if it's just the unique terrain of this place or the whole planet.

The probe has advanced a total of about a kilometer, and the previous landing crater has been left far behind, but the scenery ahead is even more monotonous, except for the endless plain or the endless plain, Zhou Xin saw that the probe could not walk to the edge of this plain for a while, so he asked the probe to stop and began to analyze the soil composition of this place, he was very curious about why the density of this planet was so low.

It took a little time for the probe to analyze the soil composition of the place, so Zhou Xin asked Voyager to switch the camera to another probe.

The location where this probe landed seems to be on the plain, seeing this scene, Zhou Xin couldn't help but be a little disappointed, but the location where this probe landed seems to be relatively just right, and a canyon appeared in front of the camera without going far. The detector walked to the front of the canyon, and the scene inside the canyon appeared on the screen, Zhou Xin saw that the canyon was not very deep, only about a few tens of meters, and the two sides of the canyon were slopes of about forty-five degrees, which did not look very steep, and the slope was thickly covered with a layer of floating soil like that on the plain. Seeing this situation, Zhou Xin asked the probe to try to go down to the bottom of the canyon, and a few seconds later, the camera on the screen slanted, and the probe was already walking on the slope.

Although the slope does not look very steep, it is still very difficult for the probe to walk on it because it is covered with a thick layer of floating soil, and the camera of the probe is constantly shaking as it advances, and Zhou Xin also sees on the screen that the floating soil on the slope is constantly sliding downward, which causes the probe to stop and stabilize itself every few steps. At a short distance of less than 100 meters, the probe advanced for five minutes to reach the bottom of the canyon.

After arriving at the bottom of the canyon, Zhou Xin saw that the scene in this place was no different from that on the plain, and the bottom was still covered with a layer of floating soil. Due to the topography, the floating soil at the bottom of the canyon is thicker than that on the plain, and from the lens, almost half of the detector is stuck in the floating soil, which has a great impact on the progress of the probe.

The probe began to make its way slowly along the bottom of the canyon, and it made a long progress, but it didn't see anything that interested it along the way. In addition to these two probes, the other probes have not yet reached the surface of the planet, and the other probe is analyzing the soil on the surface of the planet, so Zhou Xin had to continue to focus on this probe, and he discussed the situation of the planet with Spred next to him.

"What do you think of this planet?" Zhou Xin asked.

Spred frowned and thought for a moment, then he showed a tangled expression, and it was a long time before he squeezed out two words, "Desolate." Then he explained, "This desolation is different from the planets we have seen before, and although the other planets are also desolate, at least there are undulating terrains, but what we see now is no other terrain than this shallow canyon, which makes one think—" He couldn't find an adjective to describe this planet.

"I feel that way, too." Zhou Xin nodded in agreement with Spred, but then comforted, "These two probes landed very closely, maybe they just landed on the plains of this planet." ”

"Brother Captain, I'm afraid I'm going to disappoint you." Atlas's voice came out, "The probe in synchronous orbit has sent back a partial topographic map of the planet's surface, at least the parts that have been scanned by the probe, and I only see the terrain of the plains. As he spoke, a topographical map appeared on the screen.

The terrain depicted on the topographic map is not very large, only about one-tenth of the range near the equator of this planet, but it is not very small, in this range, Zhou Xin really did not see any obvious terrain fluctuations, not even a few craters that are more common on ordinary planets.

"The terrain of this planet is also - too weird." After carefully observing the topographic map, Zhou Xin spoke, "How can there be so few craters. ”

Spred nodded, "Indeed, it stands to reason that on such a large planet, and without the protection of the atmosphere, it is impossible for the crater to be so few. ”

"According to what we see now, if there are still so few craters on this planet, it means that this planet is protected by at least one satellite, which has resisted a large number of meteorites for this planet." Dart came up with an idea after thinking about it for a long time.

"Traveler, are there any moons near this planet?" Zhou Xin asked.

"The probe did not find the presence of a moon near this planet." The Voyager gave a direct conclusion.

"Didn't you? That's weird. Zhou Xin looked puzzled, "Could it be that there are really only so few meteors in this star system?" Puzzled, he pondered the question, when a report from the probe interrupted his train of thought.

"The analysis of the soil composition has been completed." "More than 99 percent of the planet's soil is made up of high-purity silica, and the rest is composed of small amounts of light elemental impurities," the probe reported. ”

"High-purity silica?" Zhou Xin was a little surprised, "All of them?" ”

"At least that's what the ground around us." The detector replied.

"High-purity silica is a good material for building high-precision electronic equipment, and we suggest that some can be collected here."

"There's nothing wrong with collecting." Zhou Xin's tone was slightly helpless, "But this doesn't help us in our current situation, what we urgently need now is the resources to repair the spaceship, not the resources to make electronic equipment." That said, he had Voyager release a construction ship to the location of the probe that sent the message.

Not long after the launch of the engineering ship, many probes landed on the surface of the planet one after another, and piles of reports were sent back to the Voyager, and Zhou Xin had to deal with them heavily.

For the next hour or so, Zhou Xin went through the images sent back by the detector. He found that most of the probes had landed on the same plains as before. It's not that the probe can't land on other terrain, it's that the probe can't find other terrain near the landing site. Only a few probes landed in the crater during the landing.

However, it looks like a crater, but it is actually a huge sand crater, because the crater is made entirely of fine silica dust, and the silica dust covered in the crater is thicker than on the plains. The first probe to land in the crater was unprepared, and it took a long time to crawl out of the dust inside the crater.

There was a lot of information sent back by the probe, and Zhou Xin could only browse it first, and leave the rest to the Voyager to deal with, but after a little browsing of the report, Zhou Xin found that no matter where the probe landed on the planet, the report sent back landed on a thick layer of dust, and these dusts were all silica dust layers without exception, and the only difference was that the thickness of the dust layer was different. But even the thinner part of the dust layer is more than half a meter, let alone thick, and even the detector did not detect the thickness of the dust layer at the landing point.

Zhou Xin asked the probe to try to dig up the thinner part of the dust layer to see what was going on on the hard surface of the planet, but because the dust layer was very thick, every time the probe dug a little down, the surrounding dust would begin to slide down to the middle, filling in the part that the probe had just dug out. As a result, the probe spent a lot of time expanding the hole to dig deeper.

Just as the probe was digging a hole, Zhou Xin remembered something, he turned to Spred and asked, "Do you think this planet misses the wandering planet we encountered before?" ”

"You mean the heavily weathered planet?" Spred replied.

"Yes, the surface of the two planets is also covered with a thick layer of silica dust, don't you think it's very similar? You say, could it be that the dust on this planet is also caused by weathering? ”

"Maybe it's possible." Spred thought for a moment, "The reason for the formation of silicon dust on the surface may be similar, but the difference between the two planets is still very large, and the density of the previous wandering planet-" He thought for a moment, "I remember, it doesn't seem to be as low as this planet." ”

While chatting with Zhou Xin, he asked the Voyager to call up the information of the wandering planet he had encountered before, he glanced at it, and then said: "Indeed, the density of that planet is one and a half times that of this planet, and the dust on the surface is not pure silica, but also contains many other impurities." Speaking of this, he showed a puzzled expression, "So how can the density of this planet be so low, this is close to the lower limit of the density of rock planets that can be formed." ”

"Who knows." Spred spread his hands, and then he thought for a moment, "Do you think this planet is also a planet that appeared in the early days of the universe, like that wandering planet?" ”

"Is it such a coincidence?" Zhou Xin looked incredulous, "Voyager, has the probe estimated the age of this planet?" ”

"According to isotopic analysis, the age of this planet is about 2.5 billion years, which is a relatively young planet." Voyager replied.

"It doesn't look like so." After listening to the Voyager's answer, Zhou Xin said, and then he put forward his guess, "Could it be that there are too many holes in the middle of this planet, which has led to the reduction of the overall density of the planet?" ”

"Brother Captain, this is impossible." Before Spred could answer, Atlas rushed to the side and said, "If there are enough holes to affect the density of the planet, this planet will collapse into a more stable structure under the influence of its own gravity." ”

Then, Voyager also reported a new piece of information, "The probe has just analyzed the vibration caused by the landing, and found that the interior of the planet does not seem to have a detailed hierarchy, but because the shock wave caused by the probe landing is too mild, the conclusions drawn by the probe may not be accurate." ”

Since the Voyager had never reported this kind of information during the previous exploration of the planet, Zhou Xinchu was slightly stunned when he heard the Voyager's report, and when he thought about it, he showed a surprised expression, "You mean that the interior of this planet is completely a whole piece?" There is no mantle and ...... core? ”
