On the way home, Su Zhe's cell phone rang. He took it out and saw that it was a power limit notification.
Relevant departments issued a power curtailment notice through the operator.
The content of the notice is that nationwide power rationing will be carried out on the first day of the Lunar New Year, which will start at 3 o'clock in the afternoon and end at 6 o'clock in the morning on the second day of the Lunar New Year.
Its purpose is to support the energy consumption of the Xuanwu defense system.
Su Zhe put his phone in his pocket and saw a red light flashing in the sky. He knew it was a sign of advance.
When I came to the door of the house, I saw my little sister and my father standing there. They looked up at the sky, trying to see something.
"Little sister! Dad! Go back to bed, there is nothing to see now."
"There is a red light, I saw a red light." Su Meiyun shouted.
At this time, Yang Xiuzhi came over and said, "Go to sleep. Your elder brother has said that there will be a beautiful meteor shower tomorrow. If you don't sleep now, you will doze off tomorrow."
"Uh! I'll go to bed then. I'm going to watch the meteor shower tomorrow." Su Meiyun said, dragging her father Su Jianguo into the house.
When Yang Xiuzhi saw her son Su Zhe coming in, she smiled and asked, "I just received a text message saying that the power supply needs to be limited to support the Xuanwu system. What should we, ordinary people, do?"
"Just don't turn on the air conditioner or high-power heater at home." Su Zhe replied.
The power curtailment notice mainly informs high-power users of electricity, especially those high-energy-consuming enterprises that rely on electricity.
"Whoever drives that thing consumes too much electricity and can't afford it." Yang Xiuzhi said, "It's more economical to use charcoal fire for heating."
After Su Zhe washed up, he took his laptop back to the room.
He was leaning on the bed with his shirt on, looking at his laptop on the quilt.
The previous second wave of attacks worked perfectly.
Three asteroid remnants with a diameter of five to ten kilometers and one asteroid remnant with a diameter of 11 kilometers.
All four asteroid debris were hit. The most important thing is that the maximum diameter of the debris after disintegration is 900 meters.
There are some wrecks with a diameter of more than five meters, but not many.
However, after the first and second waves of attacks, the fastest time for the debris to hit the earth has been advanced.
It has been advanced from 6pm to 4pm today.
At this moment, the SS-defense system is making advance progress, targeting the asteroid debris that landed in the blind spot area.
There are two results. One is to change the trajectory of the asteroid debris so that the debris is within the strikeable range.
The other is to attack large wreckage, so that the diameter of the wreckage is less than five meters.
From time to time, red beams of light are emitted from the three thousand SS-defense system subsystem bases across the country, hitting the asteroid debris more than two million kilometers away from the earth.
Now, what is displayed on Su Zhe's computer screen is the remains of an asteroid with a diameter of four kilometers.
The debris of this asteroid is more than 2.5 million kilometers away from the earth and is accelerating towards the earth rapidly.
According to the flight trajectory of the asteroid debris, the final landing point of the debris was the east coast of the Americas.
This landing point happens to be the dead zone area of the SS-defense system.
The wreckage had to be prepared in advance.
After a brief discussion in the discussion group, everyone agreed that a method should be used to change the trajectory of the debris. ….
No, you can see through the real-time monitoring screen of the SS-defense system that the wreckage is continuously attacked by red beams, and its trajectory is constantly changing.
Soon, the wreckage escaped from the blind spot area hit by the SS-defense system.
This wreckage successfully changed its trajectory.
There are also relatively unsuccessful ones. For these targets, the wreckage will be directly hit and disintegrated before the orbit change window is lost.
Su Zhe took a look at the advance calculation of the asteroid debris in the blind spot area, and it was very smooth.
Take a look at what was said in the discussion group.
All right!
What is being discussed now is the impact of asteroid debris on satellites and probes orbiting the Earth.
Relatively speaking, the farther the artificial satellite is from the earth, the higher its safety factor, and the closer the distance, the lower the safety factor.
For example, space stations in low-Earth orbit, earth observation satellites, geodesic satellites, communication satellites, etc. have extremely high risk factors.
If you think about it, you will know that when those asteroid remnants with a diameter of less than five meters hit the earth, the number will be indispensable.
Looking at the predictions made by the SS-Defense System, 90% of satellites in low-Earth orbit will be destroyed by the impact of asteroid debris.
As for the way to deal with it, it is either to avoid it or to destroy the incoming asteroid debris.
For our own space stations and satellites, avoidance and destruction are both feasible. After all, the SS-defense system can grasp the movement trajectories of those asteroid debris in real time.
The efficiency of the discussion group was still very high, and the plan was quickly come up with, which was also very straightforward.
For example, in the blind area of the SS-defense system of satellites and space stations, avoidance methods should be adopted.
If they are not in the dead zone, then use the SS-defense system to directly destroy the incoming asteroid debris, so that the space station and satellites can save power and fuel.
If the space station and satellites run out of power fuel, they will have no choice but to ask for help.
While the discussion group was discussing this, the on-orbit astronauts in the two space stations in space were busy evacuation work.
At the same time, relevant domestic departments are discussing with relevant agencies in other countries how to protect space stations and satellites.
Su Zhe looked at the actions of the SS-Defense System, and then looked at the speeches of everyone in the discussion group. Seeing that the arrangements were almost complete, he prepared to go to sleep.
At this time, Zero One and Zero Two issued two announcements one after the other.
One is to inform the two space stations of the time for the astronauts in orbit to evacuate.
The evacuation time for astronauts from the International Space Station is 6:30 am, and the evacuation time for astronauts from the National Space Station is 6:45 am.
The purpose of notification is to inform everyone.
The second is international cooperation to protect orbiting space stations and satellites.
The method of cooperation is to provide the SS-defense system to collect real-time data on the wreckage for a fee, but does not provide interception services.
This is only for satellites, and interception services will be provided for the International Space Station.
Seeing this result, everyone in the discussion group knew that after this baptism of asteroid debris, there were not many satellites left in low-Earth orbit.
Su Zhe saw the word "paid" in the notice and smiled lightly.
Put away your laptop and sleep with the light on.
It's one o'clock in the morning. ….
Go to bed early and get up early to watch the evacuation of personnel from the two space stations.
…
It’s six o’clock in the morning, Yanjing time.
In different parts of the world, no matter it is day or night, many people are either sitting in front of the TV or holding their mobile phones.
Everyone is watching the live broadcast of the evacuation of astronauts from the two space stations.
At this moment, the hottest topic on the Internet at home and abroad is the Xuanwu Defense System.
From everyone’s comments and speeches, we know that these people are not at all worried about the disaster caused by the collision of two asteroids.
Everyone agrees that the Xuanwu defense system can intercept and destroy these asteroid debris.
Everyone was just watching the excitement.
People who eat melons don’t care about the space stations and satellites in space. What they care about is the evacuation of the astronauts in orbit, when the meteor shower will start, how long the meteor shower will last, etc.
Su Zhe was woken up by the alarm clock set at a quarter past six.
He put on his coat, took his laptop and leaned on the bed.
After logging into the SS-Defense System, I looked at the results of the SS-Defense System for a few hours.
Not bad. After several hours of continuous output, the SS-defense system has cleared 70% of the asteroid debris in the blind area.
At this speed, in the next few hours, that is, before entering the dead zone time, all the asteroid debris in the dead zone area will be cleaned up.
At this time, the discussion group was still very lively.
The content of the discussion was the way in which astronauts from the two space stations return to orbit by spacecraft.
This time, the way the two parties returned was somewhat different from before.
The spacecraft no longer orbits the Earth after breaking away from the space station.
At the beginning, the space station flew to the predetermined position. After the spacecraft broke away from the space station, it relied on its own power to quickly change its trajectory and fly to the surface.
According to the plan of both parties, it only takes 40 minutes for the International Space Station's return spacecraft to reach the surface, and 50 minutes for the National Space Station's return spacecraft.
The reason for using this method of return is that the SS-Defense System can provide more accurate and detailed data in real time.
As they watched, someone in the discussion group shouted that time was up and the return spacecraft from the International Space Station began to break away.
Su Zhe glanced at the time, it was just past six-thirty.
He adjusted the display screen of the SS-Defense System and the screen was split into two.
Shown on the left is the National Space Station, and on the right is the International Space Station.
In the picture on the right, the return spacecraft detaches from the National Space Station.
Immediately afterwards, the return spacecraft was ignited and flew quickly to the surface. Its speed is getting faster and faster.
When the altitude of the return spacecraft from the International Space Station reached 250 kilometers, the time came to 6:45.
Su Zhe looked at the split screen on the left. The return spacecraft of the National Space Station moved.
Like the International Space Station return spacecraft, the National Space Station return spacecraft quickly ignites after breaking away from the space station and flies to the surface.
Time passed by, and when the International Space Station return spacecraft reached an altitude of 150 kilometers, the engine began to push back.
After entering the atmosphere, the speed of the International Space Station's return spacecraft continues to decrease.
Then comes the opening of the parachute.
Soon, the International Space Station spacecraft landed on a desert in America. ….
Soon, helicopters and cars arrived at the scene.
It can be clearly seen from the real-time footage tracked by the SS-Defense System that all four astronauts on the International Space Station landed safely.
The International Space Station's return spacecraft has just landed here, and the National Space Station's return spacecraft has entered the atmosphere.
Compared with the International Space Station's return spacecraft, the National Space Station's return spacecraft is slower.
However, the return process of the two is similar, using a series of means such as engine reverse thrust and parachutes to slow down.
The time came to 7:35 in the morning, and the National Space Station return spacecraft landed in the Gobi somewhere.
In less than a minute, all relevant personnel arrived.
At this moment, Su Meiyun staggered into the room wearing new clothes.
"Brother! Brother! Get up! Let's go get grandpa to eat together."
Su Zhe put away his laptop and said with a smile, "Get up now!"
After getting dressed and washing up, Su Zhe carried his little sister Su Meiyun to his grandfather's house.
I saw grandpa sitting in a rocking chair, humming a tune and watching TV.
What was shown on the TV was the scene of the evacuation of the return spacecraft from the two space stations.
The four astronauts brought back by the International Space Station return spacecraft have evacuated the scene, and relevant personnel are working on the aftermath.
The National Space Station returned to the spacecraft landing site. The first astronaut had already exited the spacecraft. The remaining two astronauts' physical signs were normal and they were waiting to exit the spacecraft one by one.
"Grandpa! Grandpa! It's time to eat." Su Meiyun shouted.
Su Daniu stood up and said with a smile: "Xiao Zhe! Meiyun is here!"
"Grandpa! It's time to have breakfast!" Su Meiyun shouted again.
"Okay! Okay! Have breakfast!" Su Daniu muttered while turning off the TV, "These foreign devils are really good at aerospace technology."
Su Zhe smiled.
On the way home, Su Daniu asked with a smile: "Xiao Zhe! This foreigner's aerospace technology is really good. It takes us fifty minutes to get back, but they only take forty minutes. Looking at it this way, we are still a little behind." "
"Indeed! There is a considerable distance between some places, but considering the development time, it is also..." Su Zhe explained with a smile.
Su Zhe briefly explained that after all, domestic aerospace technology started late, and any gap is acceptable.
But this is only temporary and will soon be fully surpassed.
At the end, he and his grandfather explained why it only took dozens of minutes for both parties to return this time. After all, it used to take hours, or even dozens of hours.
When I got home, my parents had already put the prepared meals on the table.
The family finished breakfast happily.
After Su Zhe helped his parents clear away the dishes, he carried his little sister Su Meiyun and went to the Su family ancestral hall with his grandfather Su Daniu.
Before going to the ancestral hall, his mother asked him to carry two small bags, one empty and one full of red envelopes.
The empty bag was for my little sister Su Meiyun, and the full bag was for my grandpa.
When we came to the ancestral hall, many people came.
Su Zhe and Su Meiyun shouted that New Year is coming when they see people.
In the process, if he met an elder, he would help his younger sister Su Meiyun to collect red envelopes. If he met a junior paying New Year greetings to his grandfather Su Daniu, he would help his grandfather give out red envelopes.
After going around, I received a lot of red envelopes and gave out a lot of red envelopes.
Entering the ancestral hall, in the middle courtyard of the ancestral hall, there were seven or eight Eight Immortals tables filled with people.
Everyone was chatting while cracking melon seeds, and at the same time watching the live broadcast of the National Space Station's return spacecraft on the big screen in the courtyard.
In the picture, the host is interviewing three astronauts who have just returned.
The three astronauts talked about their feelings, especially the scene of the collision of two asteroids and the scene of the Xuanwu defense system intercepting the debris.
They specifically mentioned the oppressive feeling of those red beams.
Su Zhe hugged his little sister and sat down with his grandfather. Listening to everyone's discussion, he shook his head helplessly.
These grandparents and uncles are not as clear about asteroids, space, etc. as the younger children.
At this time, Su Daniu began to talk, which made his grandfather and uncles dizzy.

My name is Master
