After two asteroids collided and exploded, Su Zhe's discussion group became quiet.
Like Su Zhe, the discussion group members were looking at the data scanned by the three survey telescopes in detail.
Although the possibility of a collision and explosion had been considered before, it still surprised everyone that it actually happened.
It can be said that this situation is one of the worst.
Su Zhe read the relevant data about the wreckage and participated in the discussion group.
According to known data, the fastest debris will hit the earth on the first day of the new year, that is, at 6 o'clock tomorrow night.
From this point on, the debris hitting the Earth will last for twelve hours and will not end until 6 a.m. on the third day of the Lunar New Year.
As for these wreckage, if human intervention and interception are not carried out, human civilization will be destroyed in this wreckage collision.
There is no doubt about this, because twenty-seven debris with a diameter of more than one kilometer will hit all continents and oceans, and the impact point of the debris with a diameter of thirty-five kilometers is the center of the Americas.
Such a large-scale impact of asteroid debris would leave no possibility for human beings to survive.
While Su Zhe was discussing the interception plan with everyone, Code Zero One announced a piece of news.
All countries in the world have unanimously expressed their support for the use of the Xuanwu defense system to intercept these asteroid debris through the United Nations General Assembly.
The United Nations General Assembly urgently passed a bill to support the operation.
Then, the codename Zero Two posted the target of this interception in the discussion group.
Ensure that the diameter of the asteroid remnant that fell into the atmosphere is less than five meters.
Under normal circumstances, an asteroid with a diameter of ten meters will not have an impact on the earth's surface, but considering the composition of the debris, the diameter has to be controlled within five meters to ensure safety.
The target is determined, and the next step is to formulate an interception plan.
After half an hour of discussion, the final plan came out.
Except for the seven-hour dead zone time and from 10 am to 5 pm tomorrow, the SS-defense system deployed on the ground during this time cannot intercept the wreckage. It can intercept it at other times.
As for the specific plan, when the wreckage enters a space with a radius of 300,000 kilometers centered on the Earth, the radius of the wreckage should be less than five kilometers.
When entering a space with a radius of 200,000 kilometers, the radius is required to be less than one kilometer.
The required wreckage radius for 100,000 kilometers is 500 meters.
The required wreckage radius for 50,000 kilometers is 300 meters.
The required wreckage radius of 30,000 kilometers is one hundred meters.
The required wreckage radius of 10,000 kilometers is fifty meters.
The required wreckage radius of 5,000 kilometers is thirty meters.
The required wreckage radius of three thousand kilometers is ten meters.
The required wreckage radius for one thousand kilometers is five meters.
Intercepts are carried out in stages and in different areas, but taking into account the dead time, some of them need to be implemented in advance.
While a group of experts were discussing specific interception plans, major official media and even the live Spring Festival Gala broadcast an urgent news.
The contents are the same, and two asteroids exploded three million kilometers away from the earth. The debris they produced will threaten the safety of the earth. The Xuanwu defense system will take interception measures in the future. I hope everyone will not panic. .
The reason why it is announced is because it cannot be hidden even if it is wanted.
Not long ago, the "sun" glowing with white light suddenly appeared, and then the red beam of death light emitted.
These are all visible, so it would be better for everyone to make guesses than to proactively announce them.
No, after the relevant news was announced, the speculation on the Internet about the "sun" that appeared not long ago was instantly revealed.
Those who were confused by terror disappeared instantly.
All people on earth know that asteroid debris poses a threat to the earth, and the Xuanwu defense system is about to intercept it.
When there was a lot of noise on the Internet at home and abroad, a specific interception plan came out.
After the plan came out, only a quarter of an hour passed.
That is, ten at night
At fifty o'clock, countless red beams of different thicknesses appeared in various parts of the country and shot into space.
…
After the specific interception plan was determined, the SS-defense system began to take action.
According to the plan, the SS-defense system must first deal with debris with a diameter of more than five kilometers, and there are four such debris.
There are three between five and ten kilometers.
The largest remaining wreckage is thirty-five kilometers in diameter.
The SS-defense system attacks the largest wreckage first, with a diameter of thirty-five kilometers.
Su Zhe glanced at all the subsystems of the SS-defense system and saw that most of the dead rays were preparing.
I took a closer look at the method of dealing with this thirty-five kilometer diameter wreckage.
Enable one-third of the domestic death rays, including three groups of special death rays.
Launch them concentratedly, and make sure that this huge wreckage disintegrates with one blow.
Then the same method will be used to deal with three wrecks located five kilometers to ten kilometers away.
Seeing that the preparations were almost complete, Su Zhe came to his parents' room with his laptop in his arms.
Grandpa and little sister were the only ones left in the room.
After asking, I found out that his parents were talking to others outside the door because of the sudden appearance of "The Sun".
Seeing Su Zhe holding the laptop, Su Daniu asked, "The host of the Spring Festival Gala talked about asteroids and debris before, and also said that the Xuanwu defense system would intercept them. What's going on?"
"It's just two asteroids colliding..." Su Zhe gave a simple explanation.
Su Zhe also showed the scene of the collision of two asteroids to his grandfather and little sister. He also said that the Xuanwu defense system would begin to intercept it soon, and the red beam produced by the interception would be much more beautiful than fireworks.
After hearing what Su Zhe said, the younger sister Su Meiyun quickly jumped down from the chair.
I wasn't interested in watching the Spring Festival Gala either, so I took my eldest brother Su Zhe and my grandfather Su Daniu to watch something good outside the house.
Holding his laptop in one hand and holding his younger sister Su Meiyun in the other, Su Zhe came to the open ground in front of the gate with his grandfather Su Daniu.
At this time, Su Zhe's parents were chatting with their neighbor's uncle not far away about the sudden appearance of the "sun" and the relevant media's announcement of the interception of asteroid debris.
There are fireworks exploding from time to time in some distant places.
Su Zhe did not call his parents, but went into the house and moved a small square table and three chairs.
He placed his laptop on the small square table and sat in front of it, while his grandfather and little sister sat next to him.
The three of them stared at their laptops.
Su Zhe took a look and found that the ground-related SS-defense system subsystem base was ready.
There are still three minutes left before the attack.
The screen on the laptop turned around, showing three official detectors deployed in space, and three detectors equipped with first-level death rays.
The first-level death ray mounted on it also emits a red beam.
In just ten seconds, the three first-level death rays carried by the three detectors fired red beams twelve times without interruption.
Su Zhe knew that the purpose of these red beams was not to attack the asteroid debris with a diameter of 35 kilometers, but to determine the accuracy of the SS-defense system's predictions.
The purpose is the accuracy of positioning of SS-defense systems.
Next to Su Zhe, his grandfather and little sister stared at each other, completely unable to understand.
Su Daniu was a little shocked and asked in disbelief: "Sun... Xiaozhe! Are you involved in the Xuanwu defense system?"
"Yes! We are involved!" Su Zhe nodded affirmatively, "Grandpa! Little sister! The interception will begin soon, please watch the sky."
When Su Zhe said this, the countdown to the attack had already entered. He raised his head and shouted after him.
"...5, 4, 3, 2, 1."
As soon as Su Zhe finished speaking, countless red beams of different thicknesses flashed in the sky.
Immediately afterwards, a large fireball appeared far away in the sky.
The big fireball only lasted a few seconds.
Gone.
At this moment, the fireworks in the distance dimmed.
"It looks good! It looks so good!" Su Meiyun shouted.
"This...this is the power of the Xuanwu defense system." Su Daniu exclaimed.
Su Zhe heard the exclamations of his parents and neighbor uncles not far away.
He smiled and began to see the effect of this blow.
From the real-time monitoring images of three survey telescopes, we know that this 35-kilometer-diameter asteroid debris was hit by numerous red beams at a distance of 2.73 million kilometers from the earth.
Then there was an explosion.
According to the scanning results of three survey telescopes, the effect of this strike is still good.
After the explosion of this asteroid debris with a diameter of 35 kilometers, an asteroid debris with a diameter of 11 kilometers was produced.
There is no one between five and ten kilometers.
There are only three between one kilometer and five kilometers.
Among the remaining mutilated animals, there are some from five meters to one kilometer, but more of them are below five meters.
He carefully analyzed the attack process and found that it was very different from the designed attack results.
According to the design, after this wave of attacks, the diameter of its debris will be less than five kilometers.
But as a result, a wreckage with a diameter of 11 kilometers appeared.
As for this situation, there are two reasons. The material composition inside the wreckage is not known, the distance is too far, and the attack point of the beam is slightly deviated.
Think about it, such mistakes are within the acceptable range.
At this moment, the discussion group was extremely lively, and everyone was talking about their opinions.
The results of everyone's analysis were similar to Su Zhe's.
Just when Su Zhe was reading the speeches of everyone in the discussion group on his mobile phone, he heard his younger sister Su Meiyun ask: "Brother! Is there anything good to watch?"
Su Zhe turned his head and said with a smile, "There's more!"
As he said this, he looked at the laptop. The targets of the second wave of attacks were four.
One wreckage with a diameter of 11 kilometers plus three wreckages ranging from 5 kilometers to 10 kilometers.
He looked at the countdown and shouted.
At this time, his grandfather, little sister, and his parents not far away all looked up at the sky.
After Su Zhe finished shouting, countless red beams of light appeared in the sky again.
Then, four small fireballs appeared in the sky.
The four small fireballs lasted for several seconds.
"Brother! Big brother! Is there more? Is there more?" Su Meiyun shouted.
"There's more, but it will take a long time, and it won't be as good as these two." Su Zhe explained, "Wait until tomorrow. You can watch the meteor shower all night tomorrow."
"Really? I can watch the meteor shower all night." Su Meiyun asked happily.
At this time, Su Zhe's parents and uncles came over.
Su Zhe quickly hid the SS-Defense System screen.
"What! Can we watch the meteor shower all night tomorrow?" Su Jianguo asked curiously.
Those uncles and uncles also looked at Su Zhe curiously.
Su Zhe smiled and said, "Yes! There will be a continuous meteor shower on the night of the first year of junior high school."
Those uncles and uncles didn’t understand and didn’t believe it.
Seeing that these people didn't know much about this matter, Su Zhe planned to talk to everyone.
When I was about to start talking, adults and children from the surrounding neighbors came running over.
Su Zhe's parents enthusiastically held stools and brought melon seeds and candies.
After everyone was done, Su Zhe started to talk.
He said in a way that everyone could understand that two asteroids collided three million kilometers away from the earth...
After talking for a long time, the children all understood it, but the adults did not understand it.
After asking, I found out that many of these uncles didn't even know that the earth was round, and some didn't even know what the earth was.
They don't even know the most basic concepts of the universe. It's too difficult for these uncles to understand.
He had no such idea either.
Finally, it was his grandfather Su Daniu who stood up and said: "You adults don't understand, so go home and let your children teach you. Now you just need to know that tomorrow, the night of the first grade of junior high school, there will be continuous meteor showers." .”
As soon as Su Daniu finished speaking, these uncles shouted.
What I said is that it is better to study, to understand astronomy at the top and geography at the bottom. I said that in the future, my children must be admitted to college and learn from Su Zhe.
Everyone chatted for a while, and someone shouted that it was almost midnight and wanted to go home and set off cannons and fireworks.
The same goes for Su Zhe's family. After everyone left, Su Zhe and his father Su Jianguo brought out numerous fireworks and 10,000 firecrackers and set them up.
It was just past midnight, and Su Zhe held Su Meiyun in his arms and lit 10,000 firecrackers.
For a moment, the sound of firecrackers sounded in the distance and near at the same time.
While the thousands of firecrackers burned out, the main fuses of those fireworks were lit.
The main fuse burned all the way, and the fuses of the fireworks were lit one after another.
Immediately, fireworks continued to shoot into the sky.
The family watched their own fireworks and then watched other people’s fireworks for a while.
Su Zhe helped his grandfather Su Daniu back to sleep.
On the way, Su Daniu was a little excited and asked a lot of questions about the Xuanwu defense system.
Su Zhe didn't hide anything, he picked it up and said it so that his grandfather could understand.
"Okay! Contributing to the country is what you should do." Su Daniu said excitedly, "For now, with the Xuanwu defense system, it's good that we don't bully others. We have truly stood up."
"I know! I will continue." Su Zhe smiled and nodded.
"Yes! That's right. If you don't have a country, then you have a family!" Su Daniu thought for a while and asked, "Xiao Zhe! Please tell me about the universe and the solar system. I didn't understand it before."
Su Zhe and his grandfather explained what the universe is, what the solar system is, and how the moon revolves around the earth.
At the end, he talked about the development and construction of the school in the Tamu Desert, the super factory, the three-door plan, the light pillar project, and the development of the solar system.
Although Su Daniu didn't quite understand what he heard, he finally understood that the solar system was going to be developed.
"Xiao Zhe! Are you involved in this...are you involved in all of this?" Su Daniu asked in surprise.
Su Zhe nodded affirmatively and said, "Everyone participated!"
"Okay! You are indeed my eldest grandson!" Su Daniu smiled and asked, "Xiao Zhe! The solar system is about to be developed. Do you think I can go to the moon at my age? I want to see if there is Chang'e on the moon. , Wu Gang, and Moon Rabbit."
"Okay!" Su Zhe said affirmatively.
"Boy! You can't fool your grandpa!"
"No one can fool grandpa! I will definitely take grandpa to the moon to see Chang'e!"
"good!"
