At this time, Atlas began to introduce the planet to Zhou Xin according to the data reported by the probe. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

"Brother Captain, needless to say, the orbit of this planet is the same as the first planet." The little girl in Atlas's transformation reappeared on the screen again, trying to pretend to be a serious teacher, but it was very funny to appear on her. Zhou Xin held back a smile and listened to her next words.

"The diameter of this planet is only about six thousand kilometers, two thousand four hundred kilometers smaller than the first planet we discovered, and the presence of an atmosphere has not been detected on the surface of the planet for the time being, but—" Atlas breathed, "but the probe has detected the presence of a strong magnetic field near this planet, which is about a hundred times the strength of the Earth's magnetic field." ”

"A hundredfold?" Zhou Xin was a little surprised, "This is too high, has the function of the detector been affected?" ”

"Brother Captain, don't worry, it won't have an impact." Atlas said casually, "Although the magnetic field is a hundred times stronger, it is still very small, and the detector will not be affected at all." ”

Zhou Xin nodded, "Okay, then you go on." ”

"And that's not even the weirdest of all." Atlas continued, "The probe calculated from its orbit that the mass of the planet is half that of the Earth, and the average density of the planet is four times that of the Earth, so the gravity on the planet's surface is estimated to be more than twice that of the Earth. ”

"More than twice as much?!" After listening to Atlas's report, Zhou Xin was very surprised.

"It's really more than twice as much." The little girl nodded heavily in affirmation.

"That's too big a gap." Zhou Xin recalled the data of the first planet they found in this galaxy, "Two planets located in the same orbit, the difference in size is a little bit, what is the reason for such a big difference in density, are these two planets not formed by the same cloud of matter?" Atlas, can you break down how this situation came about? ”

"Then I'm afraid you'll have to wait, brother, captain." The little girl replied seriously, "I need the probe to collect some information on the planet's surface before I can proceed with the next analysis." ”

"Okay." Zhou Xin nodded, "Then you let this probe fly around the planet first, and let's see the general situation on the surface of the planet." ”

"Okay—" Atlas replied in a long voice, and as soon as she finished speaking, the camera of the probe began to move on the big screen, and it began to slowly accelerate towards the backlit side of the planet.

The probe flew above the planet for more than ten minutes, and Zhou Xin and the others did not see any other terrain except for an obvious mountain on the surface of the planet. The main reason is that the reflectivity of the surface of this planet is too low, absorbing a large amount of stellar light, so some terrain and black shadows are completely blended together, even with the help of Voyager to analyze, it is still difficult for everyone to see the specific situation on the surface of this planet. This is even more evident on the backlit side of the planet, where even with the help of Voyager, the terrain beneath the probe is still indiscernible and the entire planet seems to be shrouded in the fog of war, and in the end, even Atlas joins the ranks of image analysis.

"No, Brother Captain." The little girl on the screen had a bitter face, "The contrast of the image is too low, and I don't know what is at all." Zhou Xin saw that even with the images processed by Atlas, there were only a few more mountains on the surface of the planet, and most of the area was still shrouded in darkness.

"Then let's let the probe fly back to the lighted side." Zhou Xin commanded, and then he asked, "Traveler, how long will it take for the previous batch of probes to land on the surface of this planet." ”

"The probe is approaching the planet and is expected to land on the planet's surface in half an hour." Voyager replied.

"Watch out for the effects of strong gravity on the planet's surface." Zhou Xin remembered the scene when the probe landed last time, and commanded the Voyager.

"Understood."

Twenty minutes later, the first probes to arrive have entered the planet's high orbit, where they will adjust their attitude and then enter the process of landing.

As before, Zhou Xin asked the Voyager to switch the screen to one of the probes preparing to land, and coincidentally, like the last time, another probe preparing to land appeared in the camera.

At the beginning, the detector in the lens was still adjusting its posture, and Zhou Xin saw that faint blue firelight was still spewing out from time to time around the detector. After more than a minute, the probe adjusted its attitude, and as the probe turned away from the direction of the planet, a fierce, but only less than ten seconds of flame, the probe's orbit began to decline. At first, the speed of descent was not very obvious, but under the influence of the planet's gravity, the speed of the probe's descent began to slowly increase. In less than a minute, the probe began to accelerate towards the planet's surface at a speed visible to the naked eye, and just as it was about to disappear to the edge of the screen, the camera began to move, and the rapidly descending probe reappeared in the center of the screen.

It didn't take long for everyone to feel that the surface of the planet seemed to be accelerating closer to the camera, and it seemed that the probe as the lens had also begun to enter the landing process, and Zhou Xin could clearly feel that the speed of the probe landing was much faster than when it landed on the silicon star, presumably under the influence of the strong gravity of the planet.

Also due to gravity, it took much less time to descend from orbit to the surface of the planet than it did when landing on a silicon star, and in just a few minutes, the probe in the lens had begun to emit a violent fire in the direction of the planet, and the figure of the probe paused slightly in front of the screen, and then began to fly towards the camera quickly.

The detector that is the lens is still descending rapidly, and in just a few seconds, the lens is very close to the detector in the lens, and Zhou Xin can even see the marks on the detector clearly.

At this time, the lens shook violently a few times, and then the speed of the ground approaching the lens began to decrease significantly, and at the same time as the detector that was the lens slowed down, the detector in front of it had ejected its own deceleration airbag, and before I saw the process of the detector in front of it touching the ground, the lens was completely covered by the airbag.

As before, after Zhou Xin heard the bouncing sound a few times, the picture quieted down, but compared with the landing on the silicon star, the bouncing sound was much denser and less frequent.

When the screen reappeared, the probe had successfully landed on the surface of the planet, no different from what they had seen in space before, the ground that appeared in front of the camera was still dark, and Zhou Xin and they could only vaguely see the terrain about 100 meters near the probe. Without allowing the probe to explore the terrain near the landing site, Zhou Xin, who was full of doubts about this phenomenon on the surface of the planet, asked the probe to start testing the soil composition on the surface of the planet first.

It took more than ten minutes for the probe to produce the results of soil analysis on the planet's surface, and this time, it was Voyager who reported the results.

"The presence of a large number of metallic elements was detected in the soil near the detector, the largest of which was iron, which accounted for 37% of the proportion." Different from the previous Atlas's lively tone, the tone of the Voyager is still so serious, "The content of titanium is not low, accounting for 13% of the proportion, in addition, there are many other rare elements that can increase the strength of the alloy, vanadium, chromium, manganese content is more than 1%, lanthanide, actinide metal content is also considerable, most of these metal elements are contained in the soil in the state of metal oxides." ”

"Most of the metal oxides are dark, that's why the color of the soil looks so dark." Atlas added later.

However, Zhou Xin did not delve too deeply into the issue of soil color, and after hearing the Voyager's previous report, he was relieved and became happy at the same time. He hurriedly asked, "What about other places, is the composition of the soil similar?" Remembering the surface of the planet he had just seen in the universe, he had an optimistic speculation in his mind.

"Your Excellency, please wait, the other probes are exploring the terrain near their respective landing sites, and this ship will give them a new order."

While the other probes were investigating the composition of the soil in various parts of the planet, Zhou Xin thought for a while, and then asked the probe who had already surveyed the composition of the soil to start digging down the landing site, he wanted to confirm how thick the metal-rich soil on the surface was. Unlike previous silicon stars, the soil around the pit wall did not easily collapse into the pit when the probe dug the crater, so in just ten minutes, the probe dug a deep pit about 10 meters downward. What excites Zhou Xin and his team is that the color of the soil at the bottom of the pit under the searchlight has not changed significantly until now, which indicates that the composition of the soil has not changed much.

After about fifteen meters of digging, other probes began to send soil analysis reports near their respective landing sites. To everyone's delight, more than half of the information sent back by the probe was similar to that reported by the first probe, and the rest of the probes landed at the same level as the previous report, although the content of soil metal elements was not as much as previously reported, but it was still very rich compared to some so-called mines on the earth. Zhou Xin carefully read the report sent back by the probe, and suddenly at the end of the report, he found that the impurities contained in those places with a slightly lower content of metal elements were actually something he was familiar with - quartz. Suddenly, a whimsical idea popped into his mind.

"Voyager, let the probe estimate the age of this planet, and - compare the quartz found on this planet with the previous silicon star to see what the composition is?" Zhou Xin thought about it for a long time, and finally decided to verify his idea.

"Hey, you don't think—" Many people in the command cabin heard Zhou Xin's thoughts, and they all showed surprised expressions, and Spred couldn't help the thought in his heart at first, and asked.

"This-" Zhou Xin scratched his head, "Actually, I came up with this idea out of nowhere, and I don't think it's very reliable, but well--we have the information on Silicon Star anyway, so it's nothing to compare." ”

When everyone heard Zhou Xin's explanation, their surprised expressions disappeared instantly, replaced by a funny expression, they all felt in their hearts that this idea was really a joke, and even Spred looked unconvinced, "Okay, but I think your idea is too outrageous." After saying this, he didn't say any more, but judging by his expression, it was obvious that he didn't believe that there was any relationship between the two planets.

However, Zhou Xin originally thought that the comparison was very simple, but it actually took nearly an hour to complete, and within this hour, all the detectors had already sent back the first detection report, and even some detectors had begun to explore the nearby terrain and sent back a part of the topographic map. In the topographic map, I saw that although the surface of this planet is very desolate, all the terrain that should exist on the planet in general, mountains, canyons, plains, basins, and so on. The only difference is that the height of the peaks on this planet is generally not very high, and in the topographic map sent back by the probe, the highest mountain peak Zhou Xin saw was only about two thousand meters, which was thought to be the influence of the planet's huge gravity - if the height exceeded two thousand meters, it would automatically collapse under the action of gravity.

At this time, the Voyager reported an anomalous phenomenon, "Captain, this ship has found that there is a strong interference in the information sent back by the probe, and according to observation, it is found that the interference probe sends back information is the strong magnetic field of this planet. ”

"Didn't Atlas say before that the planet's magnetic field has no effect on the probe?" Zhou Xin asked suspiciously.

"yes, how can such a weak magnetic field affect the detector?" Atlas followed.

"It's not that there is no impact at all, it's just that the impact is not very obvious." Voyager explained, "In addition to the large interference in the information sent back by the probe, the electromagnetic equipment on the probe also showed a slight anomaly in the planet's magnetic field. In particular, there have been obvious errors in various positioning equipment under the strong magnetic field, but this ship has adjusted this error. After a pause, Voyager added, "But as the probe stays on the planet longer, this error will become more and more apparent, and it may eventually damage the probe permanently." ”

"Oops! I forgot! Before Zhou Xin could ask a question, Atlas screamed, and at the same time, the little girl on the screen stuck out her tongue and made a very cute expression, "This is not a detector we made, if it were our detector, it would indeed not be disturbed in this environment." ”

After listening to the explanations of the Voyager and Atlas, Zhou Xin looked helpless, he thought about it, and asked the question he was most concerned about......
