Space junk is all kinds of waste left over from human activities in space.
These wastes include abandoned satellite wreckage, rocket wreckage, various parts and components of rockets and satellites dropped in space, a large number of debris produced by satellite collisions, and debris produced by anti-satellite systems crushing satellites, etc.
In addition, in order to realize long-distance radio communication in 1963, Laomei scattered 4.3 million copper needles into space, and a considerable part of them are still flying in orbit.
It is estimated that the large space junk currently in the low-earth orbit of 800 to 1500 kilometers has reached 2000 tons, and the number is more than 10 pieces.
Nie Xingyuan explained: "Take our Yanhuang as an example. Our flying speed will exceed Mach 10. At such a fast speed, once it hits something, even a piece of iron filings the size of a hair is very dangerous. It may be the end of the plane crash."
"Ah, is it that serious?"
Zhao Anxin said with concern.
Nie Xingyuan nodded and said: "That's true, but it's a matter of probability, a probability of collision on the same track, plus a probability of collision at different speeds, the aircraft may be hit by space debris in space, but The current distribution rate of space junk is too small compared to the entire space, which also makes the probability of collision very small."
Zhao An said: "That can't be taken lightly. Do we have any targeted measures for space junk?"
Nie Xingyuan smiled and said: "You don't have to worry about this, our technology can detect centimeter-level objects in orbit."
"Before each spacecraft enters orbit, we will conduct a detailed risk analysis on the future working orbit to confirm that there is no risk of collision with existing spacecraft and debris before the spacecraft can enter orbit."
"Whether it's a spaceship or an aerospace plane, it's the same."
Nie Xingyuan's explanation is still in place. If you are afraid of wolves and tigers, you can't do anything. Therefore, you must have a certain spirit of sacrifice in the aerospace industry.
But Zhao An asked again: "Then, for example, the Starlink satellites launched by the Space Exploration Corporation, will they eventually become space junk?"
As of April this year, more than 4 Starlink satellites have been launched, and Zhao An has a deadly feud with the Starlink satellites launched by Space Exploration Corporation. For this mission to the moon, Zhao An is also thinking about whether he can After going up, engage in these Starlink satellites.
It's best to find a way to take it away for him and put it in his six-compartment backpack.
"Each satellite has a lifespan limit, but if the satellite's orbit is relatively high and there is no active de-orbiting measure after the satellite fails, it can only stay in orbit for a long time."
Nie Xingyuan said: "As large-scale satellites enter orbit, the number of failed satellites will continue to increase, and the probability of collision will also increase, and a chain reaction will occur, forming a space garbage belt."
"Although SpaceX has made a guarantee that the satellites have de-orbiting measures, they will actively fall into the atmosphere and burn up after the expiration, but even so, as of now, about 2000% of the more than 3 Starlink satellites that have been launched are still completely dead. If you can’t get in touch, you will become a “Death Star”.”
"And these dead stars can be counted among the ranks of space junk."
Zhao Angong said angrily: "The imperialists will never die, we have to find a way in the future to kill and disable these harmful Starlink satellites."
"Ha ha!"
Liu Yong, who was sitting next to him, smiled and said: "That's totally fine, we can install a robotic arm on the Yanhuang like in old American movies, and then give him his Starlink satellites one by one. Picked up..."
Not to mention, the idea is totally doable.
When the Yanhuang returned to the training base, Zhao An notified the matter to the commander-in-chief Wang Xianping.
After hearing this, Wang Xianping immediately put on a serious face and said, "Isn't it nonsense?"
"Our primary task now is to successfully complete the moon landing, and we will build a base on the moon in the future. What are we still thinking about at this time?"
Well, it's still the set that puts the overall situation first.
But even though Zhao An didn't think so, he still had to approve Wang Xianping's decision. The key was that he didn't have the final decision right.
It seems that ordering an aerospace plane of its own is imperative.
Chapter 845 Unveiling Ceremony
Of course, Zhao An can order an aerospace plane. Most of the technologies, especially the key technologies, of this complete set of aerospace planes are provided by Zhao An. Then Zhao An wants to order one for himself and manufacture one according to his own requirements. frame, what's wrong with it.
Moreover, Zhao's base in Vanuatu is also preparing the lifting platform for the aerospace plane. The aerospace plane manufactured in the future can land on the takeoff and landing field of his home.
Just thinking about it makes me happy...
But in the future, when I go to space and fly around the earth, if I encounter the Starlink satellite of the Space Exploration Company, I will have the opportunity to take it away for him.
Within a range of ten kilometers, I can put it directly into a six-compartment backpack. The thing is only 2000 to [-] kilograms in size, more than [-] pieces, and only occupies four of my own compartments. Thinking of this, Zhao An did not support Wang Xianping Let go of my own affairs.
If the organization doesn't support me, then I will do it myself. I feel that there is no need to bother the organization with everything, and it's not that I don't have the strength...
Half a month passed quickly. During this period of time, Zhao An and the other four astronauts who landed on the moon have been conducting driving training every day, and they have become more and more proficient at driving the Yanhuang.
Zhao An himself also actively participated in the training. He flew the aerospace plane across the blue sky, crossed the ocean, shuttled through the clouds, and flew rapidly in the sky.
He likes this feeling very much. The extreme speed brings extreme pleasure. At the flying speed of Mach 10, mountains and rivers pass by in front of his eyes, which is too beautiful to behold.
......
The day was approaching the evening and the weather was sunny. Zhao An and the others did not participate in the training after having enough rest.
Today is the day when Yanhuang takes off to land on the moon...
The moon landing training center was decorated with flowers and branches, and colorful flags fluttered in the wind. The aerospace workers in the training center were all dressed in clean and tidy clothes, put on their exclusive hats, and sat on the viewing stage with a small flag in each hand.
On this day, most TV stations across the country are rebroadcasting the scene at this moment,
A man and a woman in well-dressed hosts stepped onto the stage and loudly reported to the camera: "Good afternoon, audience friends in front of the TV."
"At this moment, with great excitement and restlessness, I am announcing to everyone that the unveiling and lunar landing ceremony of the first aerospace plane 'Yanhuang' in China and the world begins now!"
"Today's unveiling ceremony will be broadcast live simultaneously on C1, C News Channel, C International Channel, and major webcasting platforms..."
Although it has been flying for half a month, no one knows that it can still be unveiled again and hold a grand ceremony.
At this time, some people who just turned on the TV, some who just turned on the live broadcast on their mobile phones have not figured out the situation, and the vast majority of people were beyond surprised by this sentence.
Douyin user A sent a barrage: "What the hell, I heard it right, Aeroplane!!! Is this information I can know?"
Douyin user B: "I'm sorry, when did our country become so awesome here, and the aerospace planes came out!"
Douyin user C: "Wow, I didn't expect to see our country's astronauts complete the great feat of manned landing on the moon in my lifetime. I like the astronauts and the motherland!"
Douyin user D: "The descendants of Yanhuang will drive Yanhuang to the Toad Palace to win the prize. Congratulations, I wish the astronauts a triumphant return!"
In addition to the Douyin platform, viewers on other webcast platforms have also expressed their praise.
实在是这个事情,在直播之前,根本就没有任何的消息传出来,就跟之前的可控源"发;自;小.说,群:9;8、0!2,05?8'5:6!!核聚变一样,都已经成功发电了,世人才从新闻上看到可控源"发;自;小.说,群:9;8、0!2,05?8'5:6!!核聚变成功发电的消息。
The current Yanhuang has undergone countless demonstrations, and has been personally piloted and verified by Zhao An and other astronauts. He is almost [-]% sure of driving the Yanhuang to the moon.
That's why this mission to the moon is so exciting...
Then, the host began to introduce the progress of the domestic aerospace industry in a low tone, from the launch of the first artificial satellite Dongfanghong to the exploration and return of the Chang'e series of probes.
With the deepening of the explanation, the tone of the host became more and more high-spirited: "52 years, the Chinese astronauts have gone through a long time, we have gone through ups and downs, we have gone through hardships, we have overcome obstacles, and we are indomitable, we!"
"We have finally come to today. Today, we will drive the aerospace plane developed by ourselves, soaring into the sky, flying to the distant moon, and flying to the space dream of a great country in the new era!"
......
An impassioned narration brought tears to the eyes of all the aerospace workers on the scene, and also made countless viewers who watched the live broadcast excited and bloody.
Yes, how lucky we are to be born in today's prosperous world, how lucky we are to experience this glory...
Then there are various ceremonies, speeches by leaders, and finally the appearance of astronauts.
Zhao An was naturally among them. Originally, he didn't intend to make an appearance and wanted to keep a low profile, but Fang Diwei who rushed to the training center today persuaded him, "Are you afraid of society?"
Zhao An scratched his neck and said, "How can I be afraid of society, I'm very brave, okay?"
Fang Diwei was puzzled and said: "Then why are you hiding it? Such a good thing, not to mention how glorious it is, but the first batch of Chinese who landed on the moon is enough to go down in history."
Sealing the wolf to live in Xu, bravely crowning the three armies, and being ordered by the sky, he has lived forever, honored his ancestors, and his name will go down in history...
How many men would refuse to add these four-character titles before their own names?
Feng Lang lived in Xu Huo Qubing, bravely crowned Huo Huoqi of the three armies, and was ordered by the first emperor of Qin...Thinking about it, I feel extremely domineering.
So Zhao An ended up wearing a space suit and wearing a helmet and followed behind the team, even though he was the last one.
......
Thousands of miles away in Jiangcheng, Amy, who hadn't gotten off work, was watching the live broadcast when she suddenly saw a close-up shot and jumped up excitedly like a cat whose tail had been stepped on.
"I'm sorry, look quickly, it's Mr. Zhao, Mr. Zhao!"
Amy held the live broadcast on her mobile phone and shouted excitedly to her friends.
Jessica looked at Amy and said, "Why does Mr. Zhao make you so excited? Could it be that you are very interesting to Mr. Zhao?"
"Roll the ball!"
Amy snorted, but ran over in a hurry, and said to Jessica with the phone screen: "Don't talk nonsense, I'm talking about our Mr. Zhao, Mr. Zhao is an astronaut on the moon."
Jessica took a closer look and asked suspiciously, "What is this? Where is Mr. Zhao?"
Chapter 846 Entering Outer Space
It turned out that the close-up shots could not always be reserved for Zhao An, and they had already been cut to other places.
Amy said aggrievedly: "Really, I didn't lie to you. I really saw our company's Mr. Zhao just now. He is wearing a space suit, and the host's introduction also said Zhao An."
Just as he was talking, the camera cut a wide-angle panorama of several astronauts, and put all five astronauts who were preparing to land on the moon into one lens.
Now Amy pointed at the screen excitedly and said, "Look, look, it's really Mr. Zhao!"
"What the hell!"
Jessica, An Qi, Shanshan, and Bobby all exclaimed in unison: "It's really Mr. Zhao!"
Then Bobby said: "I also said that Mr. Zhao would really be a shopkeeper, leave all the work to us, and work hard for him all day, working like an ox and a horse. He is good, he knows how to accompany his wife every day. …”
"It's only now that I found out that he secretly participated in the space mission. Now it seems that my mother is willing to work for him..."
These bold and unrestrained words provoked some teasing from the little sister: "I'm afraid you're not just trying to be a cow and a horse..."
Bobby snorted and said: "Don't think that if you don't admit it, I don't know if you think about it or not, just tell me the truth!"
"Pooh!"
An Qi, who was a little quiet, spat lightly and said: "If you think about it, you are thinking about it. I don't want you to be so unrestrained. I am on the same front as Qingrou."
It's okay if you don't say this, but if you say it, it will provoke the siege of others.
Shanshan took the lead in joking: "You also said that you are not thinking about it, and you want to stand on the same line with Qingrou. You don't know what Qingrou is thinking about. If she has no idea in her heart, the five of us can do good things in this place. Is it?"
"Hahaha..."
The girls laughed together again.
At this moment, a soft and intellectual voice came: "What are you talking about, so happy!"
The one who spoke was Ai Qingrou in business attire. She was gorgeous without any makeup, and her seriousness made her feel like a spring breeze.
"Qingrou, look quickly, your family, Zhao An, is going to take part in the mission to land on the moon in an aerospace plane..."
Amy ran to Ai Qingjudo with her mobile phone again.
Ai Qingrou blushed, and said angrily: "Don't talk nonsense, Mr. Zhao, you are a family man, we should be more careful when we speak."
He said so, but the hand that took Amy's phone was not slow. Looking at the handsome figure on the screen, he didn't know where his thoughts went.
......
At the same time, in the villa of Cuiping Villa, Zhao An's family was also watching the live broadcast around the TV.
Li Zhiyuan hugged Xiao Yuqi and pointed at the handsome figure on the TV, "Baby, do you see that, that's Dad!"
"Come on, call Dad..."
Little Yuqi, who was only a little over a month old and less than two months old, couldn't speak, but kept babbling and babbling in front of the colorful pictures on the TV.
Li Zhiyuan thought she was calling her daddy, and said happily: "Yes, that's daddy, daddy is awesome!"
Lu Xiufen, who was sitting on the sofa beside her, was also tearing up with excitement. She never thought that her son would have such a long face. At this time, she wished she could hold a loudspeaker and announce loudly that he was about to participate in the mission to the moon, for the sake of fighting for the country The person is her son.
"You say you, you are a big man, such a good thing, why cry!"
Zhao Dacheng's eyes were red, but his mouth was stiff and blamed.
......
After introducing the astronauts, Nie Xingyuan read the oath on behalf of the moon landing five, expressing the will to never give up until the goal is reached, expressing the determination to do everything to win, and expressing the spirit of working together to create success... ...
Then, the Great Elder delivered a speech, sending blessings to the five people on behalf of the people of the whole country, wishing them a triumphant return.
Amid warm applause, the aerospace plane was slowly unveiled. The Yanhuang, a sharp weapon in the future space field, was revealed to the general public for the first time.
Netizens' speeches on the live webcast platform never stopped, and the barrage floated across the screen like heavy snow.
Douyin user E: "Is this the aerospace plane? It looks so mighty and domineering!"
