Chapter 1080: Space bullet

Chapter 1107 Space Bullet
This hard-working space capsule is now quietly staying in a laboratory, like a person traveling a long distance. Now he feels a little tired and wants to take a break.
Zhao Zhongyao, Yang Chengwei and Cheng Yu have now come to this laboratory together.
When he came to the front of this space capsule, Zhao Zhongyao took a closer look. It should be said that Yang Chengwei and Cheng Yu have seen it anyway, and naturally feel that there is nothing good to see.
But for Zhao Zhongyao. It was the first time I saw this return cabin after landing!
For the situation described by Yang Chengwei in space. Zhao Zhongyao felt that it might be the sound of something wrong with the door of this space capsule. The reason why the alarm did not alarm may be because the fault is not very serious. It has not yet reached the requirements of the alarm.
Thinking of this, Zhao Zhongyao first checked the door of the return cabin. He wanted to see if there was a problem with this hatch in that place. He opened the hatch first, and then looked inside. After that, he deliberately opened and closed several times.
But he checked it again and didn't feel that there was something wrong with the door of this space capsule. It feels like everything is normal.
Cheng Yu and Yang Chengwei also stood beside Zhao Zhongyao. The two of them also looked at the door of this space capsule, and they also felt good. No matter how it is opened and closed, there will be no strange noise. Everything is normal.
"Mr. Zhao, there is no problem with this hatch, right?" Cheng Yu asked this first.
"It seems that there is no problem now." Zhao Zhongyao said, and closed the hatch again.
After closing the hatch, Zhao Zhongyao felt that there was a layer of dust outside the hatch. After all, when the space capsule passes through the atmosphere, the insulating material underneath will burn. Some smoke is produced. The smoke may form some dust on the door of the space capsule.
No, after the space capsule falls into the Gobi Desert, it will also rub some dust on the Gobi Desert. Especially the capsule bounced again after it fell. The door of the space capsule is pressed underneath. In this case, some fine sand will naturally stick to the door of the space capsule.
When Zhao Zhongyao saw that the door of the space capsule was a little dirty, he wanted to wipe the door. So, he randomly found a rag nearby and wiped it on the door of the space capsule.
But he just wiped it casually, but he felt that he had found a little problem.
Zhao Zhongyao saw that there were some small dents on the door of this space capsule. It is like a very hard metal, on the door of this space capsule, the mark left after the impact.
As soon as he saw this situation, Zhao Zhongyao suddenly felt his eyes light up, as if he understood something.
"Hey, look, there is a problem here." Zhao Zhongyao hurriedly wiped the marks on the door of the space capsule again with a rag.
After hearing what Zhao Zhongyao said, Cheng Yu and Yang Chengwei rushed over to take a look. The two of them also saw a few small dents on the door of the space capsule. It seems that something hard was left behind after impact.
"Mr. Zhao, are you saying that these small dents are the knocking sounds Yang Chengwei heard in space!" Cheng Yu probably understood what Zhao Zhongyao meant.
Yang Chengwei heard what Zhao Zhongyao and Cheng Yu said, and he was also very curious. I can’t figure out what caused these small dents. It is not easy for him to judge whether it is the strange sounds he heard in space.
"Mr. Zhao, did you mean that I was attacked by any bullet in space?" Yang Chengwei thought, since such a dent can be left on the door of this space capsule, only bullets can do it. !
When he thought of what bullet attack he was in space, Yang Chengwei felt his heart palpitations again. He was thinking, could he really be attacked by aliens.
After hearing Yang Chengwei's words, Zhao Zhongyao smiled and said: "Of course, it is possible that he was attacked by a'bullet'."
"Ah, then I was really attacked by an alien." Yang Chengwei felt nervous when he heard what Zhao Zhongyao said.
After hearing what Zhao Zhongyao said, Cheng Yu was also very puzzled. After all, this kind of alien affairs has been chasing after the wind up until now! There is no strong evidence to prove the existence of aliens.
At this time, Zhao Zhongyao smiled and explained: "Aliens are impossible. If we really encounter aliens, how could our space capsule protect our astronauts! That is not it? In minutes, the alien’s laser weapon was broken."
"What the is that! What caused the small dents on the space capsule?" Yang Chengwei quickly asked again when he heard Zhao Zhongyao say this.
Cheng Yu was also very curious. He also looked at Zhao Zhongyao and wanted him to tell the answer quickly.
"I guess that the small dents on the space capsule may be caused by space celestial bodies or space junk." Zhao Zhongyao had already guessed his own.
When it comes to space junk, Yang Chengwei and Cheng Yu can also understand. After all, the two of them also have certain aerospace knowledge, knowing that in space, there are now many artificial satellites flying in the sky!
Some of these satellites have been in use for many years and are already scrapped. These scrapped satellites cannot be recycled, and they have been flying in the sky, becoming a kind of space junk.
It can be said that there are many such obsolete satellites in space. After all, people have already launched satellites into space decades ago. Over the past few decades, humans have launched thousands of satellites into space!
There are many decommissioned satellites, just staying in the sky. Although they are no longer working, they are still flying around the earth as they did when they were working.
Some satellites have been in space for a long time, and they may also encounter impacts from small celestial bodies. Then, these satellites may be broken into small parts.
It is impossible for these small parts to fall from the sky, and they will become small satellites flying around the earth in space.
But when it comes to celestial bodies in space, this makes Yang Chengwei and Cheng Yu a little confused. Because he felt that the celestial bodies in space are all very big. It can't be as small as a bullet!
Thinking of this, Cheng Yu looked at Zhao Zhongyao in a puzzled way and asked: "Mr. Zhao, you mean that our space capsule is in space, and it may have been attacked by some scrapped satellite pieces. If you say that, then I can understand it. But what you said about space celestial bodies, I don’t understand it. Could this space celestial body be as small as a bullet!"
When Yang Chengwei heard Cheng Yu say this, he also looked at Zhao Zhongyao strangely. I just wanted to hear how Zhao Zhongyao would explain this problem.
"Of course, celestial bodies in space can also be as small as bullets. Actually, when it comes to celestial bodies in space. Us ordinary people feel that they are some very large celestial bodies, like the sun, the eight planets, and some asteroids we know. It feels like, as long as it is a celestial body in space, it must at least be a large rock with a diameter of several hundred meters!
In fact, if everyone thinks this way, it would be quite wrong. In space, there are many celestial bodies like the sun and the eight planets. But the truly dominant celestial bodies are not these very huge celestial bodies. But those very small celestial bodies.
The same is true for our solar system. Although there are celestial bodies as big as the sun and eight planets. But apart from these big celestial bodies, there are not many small celestial bodies. Between Mars and Jupiter, there is an asteroid belt with countless celestial bodies.
In the outer area of ​​Pluto, there is also a Kuiper zone, in which there are countless asteroids.
It can be said that there are many asteroids in the solar system. Although their quality is not great. But the quantity is quite impressive.
In fact, when the solar system was first formed, there were no eight planets at all. There are only a few asteroids. Large planets are all grown from asteroids. This is a very long process.
The earth may also have grown from a very small celestial body. The very beginning of the earth may be a dust in the solar system! It is this small inconspicuous dust that eventually grows into our great earth.
In the entire universe, there is also a large amount of cosmic dust. It is precisely these cosmic dust that come together to form stars and planets. Our sun may also grow from a cosmic dust.
In fact, planets and stars are not much different in nature. Their growth process may be similar. It's just that stars have a chance to grow bigger and can produce nuclear fusion inside, so the stars can also become the sun.
On the other hand, planets like the Earth, due to their insufficient mass, can only produce some high temperatures inside, and cannot form nuclear fusion at all. Therefore, it is impossible for a planet to become a sun.
As for planets with relatively large masses like Jupiter, the internal temperature is already very high. But still unable to start nuclear fusion. Therefore, Jupiter can only become a planet, not a star.
Although in the solar system, several large planets and some asteroids have already formed. It does not mean that there is no cosmic dust in the entire solar system. In the solar system, there is still a lot of cosmic dust.
These cosmic dust is like the ocean in the solar system. It is the cradle of new planets. But the birth of any new planet is a very long process. Human life is very short, and it is impossible to observe the formation of new planets.
When humans observe the universe, they can only observe some stars and planets. For small celestial bodies like cosmic dust, I am afraid it is very easy to observe.
But these small cosmic bodies are the protagonists of the universe. It is the ocean in the universe. It is the driving force that breeds and changes the universe.
Even in the solar system, there are still many such countless small celestial bodies. Even around the earth, there will be many such small celestial bodies rotating around the earth. It's just that it is difficult for us humans to observe them.
However, we humans observe them with our naked eyes. Because they are the bright lights we see across the sky in the clear night sky. Those things are small celestial bodies surrounding the earth. They are heavy in number. In the process of revolving around the earth, some will unfortunately be captured by the gravity of the earth. Then it became a ray of light on the horizon. Disappeared into the earth’s atmosphere.
The small celestial bodies that hit the space capsule this time may be such small celestial bodies like bullets. It was them that caused the small dents on the door of the space capsule. "
Zhao Zhongyao explained what he could imagine to Yang Chengwei and Cheng Yu. After the two listened, they felt very reasonable.
"It turned out to be like this! The culprit turned out to be a small celestial body." Cheng Yu echoed Zhao Zhongyao's words.
"I still think it's an alien! It turned out to be a small celestial body! Then how can this small celestial body have such a powerful force that it can knock the door of the space capsule into small dents!"
Yang Chengwei heard what Zhao Zhongyao said, although he understood a little bit. But he still didn't understand how this small celestial body could have such great power.
"Small celestial bodies fly in space, the speed is very fast. It may be tens of thousands of kilometers per hour. At this speed, it is much faster than bullets. If our space capsule and flight speed are opposite to the flying direction of these small celestial bodies If so, the force of these small celestial bodies hitting the space capsule is very large.
Therefore, these small dents like bullet marks will be left on the door of this space capsule. It is because our space capsule is in space and may be attacked by these small celestial bodies flying randomly in space. "
Zhao Zhongyao saw that Yang Chengwei still didn't understand what he was talking about. He just explained it again. Yang Chengwei understood what was going on after listening.
"It seems that our space capsule is still very dangerous in space! If this is the case, then we don't conduct spacewalk experiments very much! In this case, if the astronauts come out of the space capsule, they encounter these What do you do with the "space bullets" flying at will!"
After listening to Zhao Zhongyao's explanation. Yang Chengwei felt that it made sense. But now, he is worried about the next manned space program. Hearing from Zhao Zhongyao, the next manned spaceflight program requires the astronauts to carry out the exit activities!
This space capsule will be attacked by'space bullets' in space. Astronauts walking in space are not equally likely to be attacked by'space bullets'. If that's the case, isn't our astronauts very dangerous in space?
