Although Ma Biao is a relatively careless person, he is not sloppy at all, he carefully checks every part, and every detail is done in a standardized manner.

"There was no fault. Ma Biao said with certainty.

"What could be the reason?" Xu Jiawei said to himself, "Even if there are many unpredictable reasons in space, it can't be so unpredictable that it malfunctions for no reason." ”

A wave of unevenness has risen again and again. Xu Jiawei had a bad feeling in his heart, but he was still very calm on the surface, and he called everyone to discuss countermeasures and jointly analyze the cause of the accident.

Su Xiaojia said: "There are two reasons for the unexpected situation of acceleration in the vacuum zone, one is that it has been accelerated, but there is a problem with the instrument, and the data displayed is distorted. The second is that our original research was wrong, and there is no vacuum here. Regarding the first point, Ma Biao has repeatedly checked the equipment and can be ruled out. Then it should be the second point, there is actually no vacuum here. But the question arises again, why we scanned within 50 light years and found no matter here, which again indicates that there is a vacuum. ”

"It's a small problem, it's a big deal that I can shrink the scan area so that I can see more clearly, maybe it's not a vacuum here. The question is how could he suddenly lose contact with the laboratory? Ma Biao denied the reason for the laboratory and ruled out the reason for the spacecraft. After Lin Shanshan finished speaking, she immediately narrowed the scanning range.

Luo Dongfang and Yang Qi both said that they didn't understand technical things.

Lin Shanshan said: "There are discoveries. ”

Lin Shanshan narrowed the scanning range to 1 light year, and the surrounding celestial bodies could be seen very clearly, this is not a vacuum at all, there are abundant nebulae, these nebulae are foggy, colorful in shape and color, and move slowly, like clouds floating above the earth.

According to previous research, the whole sky here is a vacuum zone, and later through spectral and gravitational analysis, it is speculated that the vacuum is only a part of it, and the north is a cloud belt, which is far more than a vacuum. The light was too dim for the telescope to see the clouds, so it was just a guess. ”

"We broke into the cloud zone, will that be dangerous?" Yang Qi asked.

"The cloud zone is gentle, with only a small patch of mist, which is not dangerous, but the cause of this is not understood, and there is speculation that the water on Earth originally came from here. Su Xiaojia said.

"Then why can't we get in touch with the lab? Is there signal interference here?" Mr. Xu said.

"No, it's impossible for such a cloud to block out the signal. Ma Biao said with certainty.

"No, we've deviated badly from our path, and if we keep flying like this, we'll fly north-northeast. Su Xiaojia said as if she had suddenly woken up, "I have studied this area before, and this area is not on our path. ”

"So that's the case, no wonder I lost contact with the professor, and no wonder I didn't walk into the vacuum. Xu Jiawei said.

"How could we have gone off course?" Ms. Lin said.

"I see, when we were dodging that big boulder, didn't we fly diagonally to the upper left, and then the spaceship adjusted to its normal state, but the path hasn't been adjusted back, so it's like this. Xu Jiawei said.

"I guess I'm driving in the wrong direction. Luo Dongfang said.

"Zhou Wenbo, the course has been seriously deviated, please adjust the course. Xu Jiawei gave instructions to Zhou Wenbo.

"Huh?" Zhou Wenbo looked at the heading indicator, and sure enough, it was seriously deviated, "Understood." Zhou Wenbo adjusted the course to the original path, and then reported to Xu Jiawei: "Captain, there is a strange thing, after the spacecraft successfully evaded, I clearly adjusted the course back, and the course mark was also displayed correctly at that time, why did it deviate seriously while flying? ”

"Okay. Xu Jiawei said.

Xu Jiawei asked Ma Biao: "Technically, you and Zhou Wenbo are authorities, and now Zhou Wenbo can't figure out what caused it, so let's analyze it." ”

"First of all, it's not a problem with the ship itself. Second, it's not a human error. Ma Biao said.

"Why are you so sure?" Mr. Xu said.

"Because the spacecraft manufacturing technology has accumulated more than 1,000 years of experience since the early moon landing and space station, it is very mature in technology, and it has undergone strict testing after it is built, so there can be no problems in technology. At the operational level, Zhou Wenbo stands out from the competition of so many masters, and he can be called the first in the country in terms of psychological quality and operation technology, so it is impossible to make mistakes. Ma Biao said.

"Then it must be caused by an external force. It is impossible for this cloud area to have such a strong external force that can cause the direction marker to indicate incorrectly. Could it be that it has something to do with that big rock? That big stone is extremely fast, although it has a small physique, but because of its high speed, the gravitational force generated is still very large, and it once caused the spacecraft to roll in the air like a kite with a broken string, and there is such a large gravitational force, won't it cause the error of the navigation mark?" Xu Jiawei seemed to say to himself.

Lin Shanshan and Ma Biao are used to his way of thinking.

"Yes, it must be. Xu Jiawei's judgment has been unanimously agreed by everyone, "Then in the future, after we encounter such a situation, we must confirm the navigation beacon again, so as not to make the same mistake again." ”

Su Xiaojia has a strong interest in the "scenery" of the cloud area, she is constantly calculating all kinds of data, these clouds are as big as the moon, and the small ones are the size of a football field, under the light of the faint light source in the air, they look colorful and very beautiful. The clouds are all mist and are exactly the same composition as water on Earth. I have always agreed with the conjecture of my predecessors, there is a cloud area here, there will be patches of mist, and now I can actually go to the scene to witness it with my own eyes, which no one can do if they want to do, this time to be able to go to the sky, it is really a great honor to be able to come to the sky. It's just that where does this water come from? Is it from the earth, or is it sent to the earth?

"Xiaojia, seeing that you are studying so seriously, do you want to take samples?" Lin Shanshan said with a smile.

"Being able to sample is certainly the best and helps me study the formation and source of these water mists. It's just that there is a possibility of fouling, and this is not a task. Technically, it's not a problem. Su Xiaojia also said with a smile.

"If you have the opportunity to think about it when you come back, let's finish the task first. Maybe by chance during the voyage, something suddenly happened to solve the mystery in your heart. Xu Jiawei said.

"I hope so. Su Xiaojia said.

"Captain, has the scanning range always been 1?" Lin Shanshan asked.

"The water mist here won't affect the ship, so let's restore it to 100, see far, it's safer. Xu Jiawei said, "Let's rest for a while, there is nothing to do." ”

The spacecraft was still flying at a speed of 100, and Xu Jiawei asked Su Xiaojia: "When will it be able to fly to a vacuum at this speed?"

"I can't fly. ”

"What do you mean?" Xu Jiawei was puzzled.

"If you turn back to the vacuum zone, and then fly out of the vacuum zone to the direction of the gravitational source, you have to enter the cloud area again, so it will take more time, now it is to take a shortcut and fly straight to the direction of the gravitational source, and then adjust back to the original path after finding the gravitational source, so that the time is saved. Su Xiaojia said.

"You're right. How long is it going to be?"

"If there are no special circumstances, it will take a month. ”

"A month in space is not a long time, but for a professor, if he loses contact for a month, the professor will go through a lot of hardships and live like years. Alas......" Xu Jiawei couldn't help but sigh.

"Captain, you have to calm down, what do you want us to think when you sigh, not to mention that the professor's psychological quality is so strong, it won't be as terrible as you think. Lin Shanshan quipped.

"Yes, even if you want to sigh in your heart, you can't show it. Su Xiaojia said.

"Haha, the two beauties were right in their criticism. Xu Jiawei said, "Xiaojia, what do you mean by the special circumstances you just mentioned?"

"For example, this area hides a very small mass, so small that it is impossible to detect it on Earth, but a miniature star with a certain gravitational pull us, and a passer-by like that big rock piggybacks us for a while. Su Xiaojia said with a smile.

"I see, then stay in peace for a month, there will be almost no such situation. Xu Jiawei said.

"It's not so absolute, we know so little about space, anything is possible. ”

"Oh?"

Lin Shanshan said: "I agree with Su Xiaojia's opinion, any accident in space will happen, which of the three things we have experienced so far is not an accident? ”

"It makes sense, it makes sense, the criticism is right, we should change our thinking, we are not earthlings now, and we can no longer use the thinking of earthlings to consider problems. Ha ha. Xu Jiawei said, "But I don't know what the earthlings think of us, we have been missing for several days, and the professor must be anxious." ”

"That's for sure, if we can't get in touch again, we may be removed from the planet. Ma Biao said.

"Then we will become a pioneer in the exploration of outer space with honorable dedication, and our glorious deeds are recorded in astronomical academies around the world. How interesting, haha. Su Xiaojia said.

"When the time comes, the National Astronomical Academy will definitely erect a statue for us to pay homage to future generations. Luo Dongfang said.

"It's not going to be so unlucky, we've done our homework while we're on Earth, and the occasional deviation doesn't mean much. Yang Qi said.

"At least a long month before we can get in touch, and our professor's hair will turn gray. Xu Jiawei said.

"With the Professor's wisdom, he won't approve of our disappearance like this, he firmly believes that we will be connected, and he won't lose his hair so easily. Lin Shanshan said.

"What do you think the professor is thinking at the moment?" Xu Jiawei asked Lin Shanshan.
