The bus carried Su Zhe and his party back to Lingzhou University of Technology.
Most of the group went back to their homes.
Su Zhe, Fan Xiaoming, Ning Changsheng, Ning Qiaoqiao, and Bao Zhengyi arrived at the director's office of the collision building after having dinner in the cafeteria's self-operated restaurant.
The five of them sat around the sofa, drinking tea and chatting.
While chatting, Fan Xiaoming's girlfriend called and informed him that the orbital data of two asteroids that may collide had been sent by email.
Fan Xiaoming printed five copies of the relevant orbit data, and each of the five people had one copy.
He also thoughtfully prepared pens and scratch paper.
Several people smiled and each took a copy of the orbital data and started reading it.
Half an hour later, the respective calculation results came out.
The result is the same as what Wen Minghui, director of the National Astronomical Observatory, said, regardless of the time or location of the collision.
"What a trap!" Fan Xiaoming put down the pen in his hand and said, "Based on the current detected data, if nothing unexpected happens, the two asteroids will collide."
"To be honest, the American Space Agency is still very powerful. It perfectly controlled the impact of the probe on this ten-kilometer asteroid, causing its orbit to change as expected. But I didn't expect..." Bao Zhengyi smiled bitterly.
The email Fan Xiaoming received not only contained orbital data about the two asteroids, but also the whole story.
Three months ago, the American Space Agency used a decommissioned probe to impact a ten-kilometer-sized asteroid.
The whole process was very successful.
The asteroid's post-impact orbit was exactly as predicted.
After the news came out that the probe had hit an asteroid, many people around the world expressed concern.
In this regard, the American Space Agency responded, saying that the impact of the probe only slightly changed the orbit of the asteroid and would not produce bad results.
But one day after the probe hit the asteroid one month later, observatories and other institutions in various countries tracking the asteroid discovered that the asteroid's orbit had changed again.
Through analysis of the data collected through tracking, it was found that an asteroid several dozen meters in size hit the asteroid, causing the asteroid's orbit to change again.
The result of the change is that this ten-kilometer-sized asteroid will collide with an a150-kilometer-sized asteroid.
"With current science and technology, it is impossible to lock all asteroids." Fan Xiaoming explained, "Just like the asteroid that is tens of meters in size, it is completely outside the range of tracked asteroids, and everyone has seen the result."
"Based on the current data, it is no surprise that these two asteroids are 80% going to collide." Ning Changsheng thought for a while and said, "I think all countries will take action and cannot just sit still and wait for death."
Several people smiled and nodded.
After chatting for a while, several people left.
Ning Changsheng and Ning Qiaoqiao went back to rest, and Fan Xiaoming took Bao Zhengyi to visit the electron-positron collider under construction.
Su Zhe sat in front of the computer in the office and typed on the keyboard. He wanted to complete the final summary of mathematics and physics knowledge.
I was busy from seven o'clock to ten o'clock in the evening, and finally completed it.
After completion, the written knowledge was packaged, encrypted, and uploaded to the data center of the Four Books Society.
After doing this, when Su Zhe was about to find textbooks to study, Fan Xiaoming and Bao Zhengyi came to the office talking and laughing.
The three of them gathered together and chatted about the development plan of the Jiutian Research Center.
…
The next day, Su Zhe, Ning Changsheng, Ning Qiaoqiao, and Bao Zhengyi came to Lingzhou Optoelectronics Research Institute again by car.
It was still Zhang Gaoming who greeted them.
This time, Su Zhe and others followed Zhang Gaoming to a small conference room.
At this time, there were more than twenty people sitting in the conference room. Seeing the arrival of Su Zhe and his party, these people stood up one after another.
The first time Su Zhe saw the conference room, he noticed Professor Wen Minghui, director of the National Astronomical Observatory.
He had met some other people in the conference room yesterday.
Seeing that everyone was here, Zhang Gaoming said with a smile: "This special meeting mainly talks about the deployment of the SS-defense system... Let me introduce to you, this is the equipment headquarters..."
Both Android and Apple are available. 】
There were twenty-nine people in the conference room, including Zhang Gaoming. Except for Su Zhe, the others were either heads of important departments or senior figures in academia and industry.
After the introduction, the "target" that the defense system needs to defend began to play on the big screen in the conference room.
Its defense space is a spherical space with the earth as the center and a radius of one million kilometers.
The individual targets of defense range from low-flying drones to asteroids hundreds of kilometers in size in space.
Watching the video, some people were surprised, some were stunned, and some fell into deep thought...
After the video ended, someone immediately asked whether this goal was too big, and said that it couldn't be done under the current situation.
Zhang Gaoming said with a smile: "The target is higher! Besides, the space targets we defend do not include the airspace of other countries, that is, the space 100 kilometers above the territory of other countries. The rest are within ours." Within the defense range, everyone can rest assured that we are a peace-loving nation and will act in strict accordance with international law."
Everyone nodded.
Someone shouted with a smile, saying that space is so big, there is no need to work around the earth, we should look into space. They also said that resources and energy are needed in space. Whether it is building a space city or transforming the planet, it is better than on the earth. Involution is more promising.
Applause erupted in the conference room.
With the goal in place, everyone began to discuss the feasibility of the goal.
One morning passed, and the result of the discussion was that this goal should be achieved in two steps.
First, ground deployment.
Second, space deployment.
At this stage, the main focus must be on ground deployment.
After the deployment is completed, the security of the national airspace can be ensured, and threats can be effectively intercepted whether they come from inside the atmosphere or outside the atmosphere.
The completion of ground deployment means that "home" will not be threatened.
Then comes space deployment.
With the current level of science and technology, space deployment is very difficult.
The most critical issue is space transportation capacity.
Don’t be too hasty with this step, you can take your time.
…
After lunch, everyone returned to the conference room.
Everyone gathered around Su Zhe and asked if the heavy photon aerospace engine described in the paper "On the Manipulation of Atoms by Electromagnetic Waves" could be realized and when it could be realized.
Su Zhe did not answer directly, but said that the heavy photon aerospace engine mentioned in the paper is just a concept.
Everyone was greatly disappointed when they heard what Su Zhe said.
Then everyone discussed that current space rockets are inefficient and risky.
It is said that there are endless resources and energy in space, which can be seen but cannot be mined.
As they talked, everyone talked about Europa, Proxima Centauri, and finally Europa 89 and Europa 90.
Everyone knows that these two newly discovered satellites contain a lot of gold, iron and other metals, and they also know that the metal resources of these two satellites are exposed in space.
Relatively speaking, these metal resources are very easy to mine.
In the afternoon, the special meeting continued.
Let’s start talking about the details of ground deployment.
"When considering ground deployment, you must consider the factors of energy and computing power. After all, the SS-defense system highly relies on computing power and energy. Actually! The only thing it relies on is energy. You must know that computing power also relies on energy. ." Zhang Gaoming reminded with a smile.
After Zhang Gaoming finished speaking, a video of national energy distribution began to play on the big screen.
It is easy to find from the video that whether it is the northeast, east or southeast, these places have energy supply capacity, but the consumption is also large.
The energy supply in central China is also not very strong.
The better places are in the west and northwest.
There are two situations to consider for ground deployment.
One is that in normal times, the beam weapons in the SS-defense system will not be used at this time. What consumes energy is the four-dimensional optical positioning technology system in the SS-defense system.
The other is an emergency situation. The SS-defense system is fully activated. Once the beam weapon-death ray is used, especially on a large scale, the energy required will be huge.
The video ended and everyone started discussing.
Combining energy, strategy and other factors, everyone discussed a preliminary ground deployment plan.
The country is evenly divided into three thousand small grids, and each small grid is equipped with a set of SS-defense system subsystems.
The ss-defense system subsystem refers to a complete four-dimensional optical positioning technology system and beam weapon-dead light attack system.
Then equip SS-defense system subsystems with different levels according to the importance of the region.
According to Zhang Gaoming.
The ss-defense system subsystem is divided into four levels, including special level, first level, second level and third level.
Among its four levels of SS-defense system subsystems, the four-dimensional optical positioning technology systems are similar, but the difference is the detection range.
But the biggest difference is the beam weapon-death ray attack system.
The third-level beam weapon-death ray attack system has the lowest upper limit of attack power, which is reflected in the caliber of the death ray emitter.
The special beam weapon-death ray attack system has the highest attack power limit, and the caliber of its death ray emitter will reach ten meters. With the advancement of technology, the caliber will be increased.
According to theoretical calculations, the power of a death ray emitter with a diameter of ten meters can directly destroy an aircraft carrier.
The disadvantage is that it consumes a lot of energy.
"Director Su! We don't know much about the optoelectronic chips you have developed. We don't know how stable the optoelectronic chips made with the 0.5nm process are? What is their performance? Can they be used in SS-defense systems?" Zhang Gaoming looked at Su Zhe Multiple questions were asked at once.
Su Zhe smiled and said affirmatively: "The 0.5-nanometer photoelectric chip is very stable, its performance is more than ten times that of chips of the same specification, and it is more power-saving. There is no problem at all when used in SS-defense systems. "
"More than ten times, that's great." Zhang Gaoming said with a smile.
In the conference room, some people were very calm and some were surprised when they heard Su Zhe's answer.
Obviously, some of these people know about optoelectronic chips, and some of them have heard of it for the first time.
"Director Su! When will this 0.5nm optoelectronic chip be mass-produced?" Zhang Gaoming asked with a smile.
"Three months at the earliest!" Su Zhe replied with a smile.
"Okay! Okay..." Zhang Gaoming shouted while applauding.
The crowd applauded.
"Director Bao! I wonder how the production of femtium-level lenses will be in the future? In the ss-defense system, whether it is the beam weapon-dead light or the four-dimensional optical positioning technology system, a large number of femtium-level lenses are needed. When will you be able to produce large quantities of them?" Mass production?" Zhang Gaoming looked at Bao Zhengyi and asked.
"The multiple synchrotron radiation devices we built require a one-year construction period, and large-scale mass production will take another year." Bao Zhengyi answered.
"One year! It's not that long." Zhang Gaoming nodded.
Some people expressed their opinions.
"I know that the normal speed of synchrotron radiation equipment construction cycle is upwards of three to four years, and the one-year construction cycle is very fast."
"The SS-defense system supporting facilities also need time to build, and one year is just right."
"We don't have to be in such a hurry. It would be good to complete the ground deployment of the SS-defense system within five years. It will be deployed nationwide, of which there will be at least three thousand SS-defense system subsystems..."
…
Suddenly, Professor Wen Minghui, director of the National Astronomical Observatory, stood up and said seriously: "No! Five years is too long. We need to complete the ground deployment of the SS-defense system within one year, no... one year It’s still too long, we have to do this in eight months.”
"One year...eight months...this is impossible!" Zhang Gaoming shook his head.
"How could it be done in such a short period of time? It's impossible."
"Even if the infrastructure of the SS-defense system can be completed, the corresponding equipment cannot be manufactured."
"There's no need to be in such a hurry! We can take our time."
…
Everyone was talking to each other.
When Wen Minghui heard what everyone said, he became even more anxious and said with a worried look: "Comrades! Don't you know that two asteroids will collide three million kilometers from the earth in four months? Think about it, everyone, if these two asteroids collide and develop in the worst direction, our earth will suffer, and it is very likely that the end of our humanity will come."
"I know!" Zhang Gaoming nodded, "But the situation is not that bad! Even if two asteroids collide, the debris will not fall towards the earth. Even if it comes towards our earth, we still have the moon to block it. We want to correct it It’s difficult to create a threat to humans.”
Everyone nodded.
"Comrades! We can't be so optimistic. We have to prepare for the worst. We can't gamble with the fate of mankind." Wen Minghui shouted, "I tell you, other countries have already made preparations, but those preparations are of little use. , and we have the ability to stop... If it were before, I wouldn't say anything. Anyway, we didn't have that ability. The result would be the same whether we did it or not. We could only pray secretly, but now we are different. We have that ability. We have the power to prevent disaster."
"This..." Zhang Gaoming hesitated.
Everyone looked at Wen Minghui.
"I know what everyone is thinking. They all think that the possibility of an asteroid hitting the earth is unlikely, but we have to prepare for the worst." Wen Minghui explained, "Furthermore, no matter what, we need the SS-defense system. Why not deploy it faster? For the sake of all mankind, we should complete the deployment in the shortest possible time."
Zhang Gaoming thought for a while and looked at Su Zhe.
