On the way home, Su Zhe's mobile phone rang, took it out to take a look, and found that it was a power rationing notice.

The relevant department issued a power rationing notice through the operator.

The content of the notice is that on the first day of the new year, that is, starting at 3 o'clock in the afternoon and ending at 6 o'clock in the morning of the second day of the new year, there will be a nationwide power rationing.

Its purpose is to support the energy consumption of the Xuanwu defense system.

Su Zhe put his phone in his pocket and saw a slight red beam of light flashing in the sky, and he knew that this was a pre-measurement.

When they came to the front of the house, they saw my little sister and my father standing there, and the two looked up at the sky, wanting to see something.

"Little sister! Father! Go back to sleep, there's nothing to see now."

"There's a red light, I see a red light." Su Meiyun shouted.

At this time, Yang Xiuzhi came over and said, "Go to sleep, your eldest brother has said that there will be a beautiful meteor shower tomorrow, if you don't sleep now, you will doze off tomorrow."

"Huh! Then I'll wash and sleep, and I'll see a meteor shower tomorrow." Su Meiyun said and pulled her father Su Jianguo into the house.

Yang Xiuzhi saw that her son Su Zhe also came in, and asked with a smile: "I just received a text message, saying what Xuanwu system is to be supported by power rationing, what should we ordinary people do?"

"You just don't have to turn on the air conditioner or the high-power heater at home." Su Zhe replied.

The power rationing notice is mainly intended for high-power users, especially those with high energy consumption that rely on electricity.

"Whoever drives that thing, it's too power-hungry to use." Yang Xiuzhi said, "It's better to use charcoal fire to keep warm."

After Su Zhe washed up, he took his laptop back to his room.

He leaned back on the bed in his shirt and looked at his laptop on the covers.

The effect of the previous second wave of attacks was perfect.

Three asteroid wrecks with a diameter of five to ten kilometers and one asteroid wreck with a diameter of eleven kilometers.

All four asteroid wrecks were hit, and the most critical thing is that the maximum diameter of the wreckage after disintegration is 900 meters.

Among the wreckage with a diameter of more than five meters are some, but not very many.

However, after the first and second waves of attacks, the debris hit the earth at the earliest.

It was brought forward from 6 p.m. today to 4 p.m.

At this moment, the SS-Defense system is making an advance against the asteroid debris that landed in the dead end area.

There are two results, one is to change the trajectory of the asteroid debris so that the debris is within the range of the strike.

The other is to attack large wrecks so that the diameter of the wreckage is less than five meters.

From time to time, red beams of light shoot out from the 3,000 SS-defense subsystem bases across the country, hitting the asteroid wreckage more than 2 million kilometers away from the earth.

Now, Su Zhe's computer screen shows the wreckage of an asteroid with a diameter of four kilometers.

The wreckage of this asteroid is more than 2.5 million kilometers away from the Earth, and it is rapidly accelerating towards the Earth.

According to the trajectory of the asteroid wreckage, the final landing site of the asteroid is the east coast of the Americas.

This landing site is exactly the dead end of the SS-defense system.

I had to do a good job of measuring the wreckage in advance.

After a brief discussion by the discussion group, everyone agreed to adopt a method to change the trajectory of the wreckage. ….

No, through the real-time monitoring footage of the SS-Defense system, it can be seen that the wreckage is constantly attacked by a red beam, and its trajectory is constantly changing.

Soon, the wreckage came out of the dead zone of the SS-defense system.

The wreckage's change of trajectory was successful.

Relatively unsuccessful, for these targets, before losing the orbit change window, the wreckage will be directly hit and disintegrated.

Su Zhe looked at the amount of advance made by the asteroid wreckage in the blind angle area, and it was very smooth.

Take a look at the presentations in the discussion group.

All right!

Now the discussion is about the strike of asteroid debris on artificial satellites and probes in Earth orbit.

Relatively speaking, the farther away an artificial satellite is from the earth, the higher its safety factor, and the closer the distance, the lower the safety factor.

Space stations in low-earth orbit, earth observation satellites, geodesic satellites, communication satellites, and so on, are particularly dangerous.

If you think about it, when the debris of an asteroid less than five meters in diameter hits the Earth, that amount is indispensable.

Looking at the predictions made by the SS-Defense system, 90% of the 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 asteroid wreckage that hit it.

For their own space stations and satellites, it is feasible to avoid and destroy, after all, the SS-defense system can grasp the trajectory of those asteroid debris in real time.

The efficiency of the discussion group is still very high, and the plan is quickly come up with, and it is also a very direct plan.

For example, satellites and space stations in the blind spot area of the SS-defense system adopt the method of avoidance.

If it is not in the dead end area, then use the SS-defense system to directly destroy the asteroid wreckage that hits, so that the space station and satellites can save power fuel.

If the space station and satellites run out of fuel, they will have to ask for more than they can do.

While the discussion group was discussing this, the astronauts in orbit from the two space stations in space were in full swing to evacuate.

At the same time, the relevant domestic authorities are discussing with other national authorities how to protect the space station 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, and when he saw that the arrangement was almost complete, he prepared to sleep.

At this time, Zero One and Zero Two issued two notices one after the other.

The first is to inform the two space stations of the time of evacuation of astronauts in orbit.

The evacuation time for astronauts on the International Space Station is half past six in the morning, and the evacuation time for astronauts on the National Space Station is six forty-five in the morning.

The purpose of the notice is to get everyone.

The second is international cooperation for the protection of space stations and satellites in orbit.

The way of cooperation is to provide the SS-defense system with real-time data on the collection of wreckage, but not to provide interception services.

This is only for satellites, and for the International Space Station, interception services will be provided.

Seeing such results, everyone in the discussion group knew that through this baptism of asteroid wreckage, there were not many satellites left in low-Earth orbit.

Su Zhe saw the word "paid" in the notice and smiled faintly.

Put away your laptop and sleep with the light on it.

It's one o'clock in the morning. ….

Go to bed early, and wake up in the morning to watch the evacuation of the personnel of the two space stations.

……

Six o'clock in the morning Yanjing time.

In different parts of the world, 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 in orbit.

At this moment, the hottest topic on the Internet at home and abroad is the Xuanwu defense system.

From the comments and statements of the people, we know that these people are not at all worried about the disaster caused by the collision of the two asteroids.

Everyone agreed that the Xuanwu defense system could intercept and destroy these asteroid wreckage.

Everyone is in the mood of watching the excitement.

The people who eat melons don't care about the space stations and satellites in space, they are concerned about the evacuation of astronauts in orbit, when the meteor shower starts, how long the meteor shower lasts, etc.

Su Zhe was woken up by the alarm clock set for a quarter past six.

He put on his coat and grabbed his laptop and leaned against the bed.

After landing on the SS-Defense system, I took a look at the results of the SS-Defense system for several hours.

Not bad, after a few hours of continuous output, the asteroid wreckage intercepted by the SS-Defense system in the blind spot area has been cleared seventy percent.

At this rate, the cleanup of all the asteroid debris in the dead zone will be completed in the next few hours, that is, before entering the dead time.

At this time, the discussion group was still very lively.

The discussion was about the way in which astronauts from the two space stations in orbit would return in spacecraft.

This time, the way both sides returned was somewhat different from before.

The spacecraft no longer orbits the Earth after detaching from the space station.

At the beginning, the space station flew to a predetermined position, and after the spacecraft left the space station, the spacecraft quickly changed orbit and flew to the surface with its own power.

According to the plans of both sides, it will take only 40 minutes for the ISS to return to the spacecraft to reach the surface, and it will take 50 minutes for the National Space Station to return to the spacecraft.

The reason why this way is returned is that the SS-Defense system is able to provide more accurate and granular data in real time.

As I watched, someone in the discussion group shouted that the time was up, and the return spacecraft of the ISS began to detach.

Su Zhe glanced at the time, just after half past six.

He adjusted the display of the SS-Defense system, and the screen split in two.

The National Space Station is shown on the left, and the International Space Station is shown on the right.

In the picture on the right, the returning spacecraft detaches from the National Space Station.

Immediately after, the return spacecraft ignites, and the return spacecraft flies quickly towards the surface. It's getting faster and faster.

When the ISS returned to the altitude of the spacecraft at 250 kilometers, the time came to 6:45.

Su Zhe looked at the sub-screen on the left, and the return spacecraft of the National Space Station moved.

Like the ISS return spacecraft, the NSS return spacecraft quickly ignited and flew to the surface after detaching from the space station.

As the minutes ticked by, when the ISS return spacecraft reached an altitude of 150 kilometers, the engines began to thrust back.

After entering the atmosphere, the speed at which the ISS returns to the spacecraft decreases.

Then the parachute opens.

Soon, the ISS spacecraft landed on a stretch of Gobi in the Americas. ….

Soon, helicopters and cars arrived at the scene.

From the real-time footage tracked by the SS-Defense system, it is clear that all four astronauts on the ISS have landed safely.

The ISS return spacecraft has just landed, and the National Space Station return spacecraft has entered the atmosphere.

The National Space Station is slower to return to spacecraft than the International Space Station (ISS).

However, the process of returning to the two is similar, using a series of means such as engine thrust reverser and parachute to slow down.

At 7:35 a.m., the National Space Station return spacecraft landed in the Gobi somewhere.

In less than a minute, all the relevant personnel were present.

At this moment, Su Meiyun staggered to the room in her new clothes.

"Big brother! Eldest brother! Get up! Let's go and call grandpa for dinner."

Su Zhe put away his laptop and said with a smile, "Get up now!"

After getting dressed and washing, Su Zhe came to his grandfather's house with his little sister Su Meiyun in his arms.

I saw my grandfather sitting in a rocking chair, humming a little song and watching TV.

The TV showed the two space stations returning to the spacecraft and evacuating.

The four astronauts brought back by the ISS return spacecraft have been evacuated from the scene, and the relevant personnel are working on the aftermath.

The National Space Station returned to the spacecraft landing site, the first astronaut had already left the warehouse, and the remaining two astronauts had normal physical signs and were waiting to be released in turn.

"Grandpa! Grandfather! It's time to eat." Su Meiyun shouted.

Su Da Niu stood up and said with a smile, "Xiao Zhe! Miyun is here!"

"Grandpa! It's time for breakfast!" Su Meiyun shouted again.

"Good! Good! Have breakfast!" While turning off the TV, Su Daniu muttered, "This foreign devil's aerospace technology is strong."

Su Zhe smiled.

On the way home, Su Da Niu smiled and asked, "Xiao Zhe! This foreigner's space skills are really good, it takes us 50 minutes to come back, and they only need 40 minutes, so looking at it this way, we are still a little worse."

"Indeed! There is a lot of distance in some places, but considering the development time, it is also ......," Su Zhe explained with a smile.

Su Zhe explained simply, after all, domestic aerospace technology started late, and it is acceptable that there is a gap.

However, this is only temporary, and it will soon be surpassed across the board.

In the end, he and his grandfather explained why it only took a few dozen minutes for both sides to return this time, after all, it used to be hours, or even dozens of hours.

When I got home, my parents had already brought the prepared meal to the table.

The family happily finished breakfast.

Su Zhe helped his parents clean up the dishes and chopsticks, and he took his little sister Su Meiyun and his grandfather Su Da Niu to the Su family ancestral hall.

Before going to the ancestral hall, his mother let him carry two small bags, one was empty and the other was full of red envelopes.

The empty bag is for the little sister Su Meiyun to pack red envelopes, and the bag full of red envelopes is for grandpa.

When I came to the ancestral hall, many people came.

Su Zhe and Su Meiyun shouted that the New Year was coming soon.

In this process, when he met the elders, he would help the little sister Su Meiyun to collect red envelopes, and if he met the juniors to give his grandfather Su Daniu a New Year's greeting, he would help his grandfather send red envelopes.

After a circle, I received a lot of red envelopes and sent out a lot of red envelopes.

Entering the ancestral hall, in the middle courtyard of the ancestral hall, seven or eight tables of eight immortals were full of people.

Everyone chatted while knocking melon seeds, and at the same time watched the live broadcast of the National Space Station's return to spacecraft being played on the big screen in the middle 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 interception of the wreckage by the Xuanwu defense system.

They specifically mention the oppressive feeling of those red beams.

Su Zhe sat down with his little sister in his arms, listening to everyone's discussion, he shook his head helplessly.

These grandfathers and uncles don't know much about asteroids and space yet.

At this time, Su Da Niu began to talk eloquently, talking about the dizziness of his grandfather and uncle.
