Hammer of Technology

And the mentor is obviously very supportive of his love affairs.

For example, a month later, Ning Wei called him over and gave him six tickets to the Olympic opening ceremony.It is definitely the best position, the third row from the inside to the outside of the north seats of the Honeycomb Plaza, and it is still in the middle. Generally speaking, this position is often scanned by cameras, because it is full of big people.

Therefore, tickets in this area are basically impossible to buy. In Chen Diancheng's view, this is because Director Ning spared no effort to help him save face, which also made him look forward to the Olympic opening ceremony. However, when the time comes to August, the Olympic Games When it was really time to come, this young man became nervous again...

Especially when he learned that his father-in-law and mother-in-law had already booked a ticket to fly to the capital, he became even more nervous.

But this is unavoidable, after all, Wen Yimo was raised by the two people, even though Wen Yimo had already told Wen's father and Wen's mother about his existence, and he even met the two elders in the video, It seems that the two elders are quite satisfied with him, but they are still a little nervous...

How to relieve this tension, Chen Diancheng doesn't really want to communicate with his parents, but really wants to chat with his mentor.It's a pity that there are almost no people from Director Ning in the yard...

Yes, since the end of July, Ning Wei has rarely appeared in the yard.

The opening ceremony is about to begin, and it is indeed too busy.

……

The Tiangong space station is 423 kilometers away from the earth.

About three days ago, the three astronauts finally launched the launcher from the ground according to the established mission. According to the instructions and the guidance of the ground, they firmly fixed the launcher together with the specially designed bracket at the pre-designed position, and for The specially designed remote-controlled tilting stand was powered on, and then connected to the space station's system.In this way, the emission angle of the laser can be automatically controlled by the system.

Now they have received instructions to start preparations for the orbit change, and to conduct a laser test launch after passing through a predetermined coordinate point in 10 minutes.This also means that the space station needs to bypass the satellites below, and after arriving in an orbit about 386km from the earth for a short period of half an hour, it will return to its current fixed orbit.

Of course, during the entire orbit change process, Huaxia Aviation Center has already greeted the departments in charge of the aerospace industry in other countries in the world a week in advance. The reason given is to conduct a space station orbit change performance test to cope with more complex space orbits in the future. The environment is justified.

For the astronauts on the space station, there is probably one more daily task.

Luckily, most operations are automated.In addition to the laser generation period, the supplies sent up last time also included the fuel needed for this test.But speaking of it, this is a very expensive test. If you move it like this, if you count the delivery fee, tens of millions will be wiped out.But then again, at least for now, any extraterrestrial activities are extremely expensive.

Fortunately, Tiangong's daily attitude control adjustment uses a control moment gyro, and the attitude control power fuel consumption is almost zero in orbit.

……

The remote command center under the Huaxia Aviation Bureau.

"Academician Ning, the Tiangong station has started to maneuver towards the target point as planned, and it is expected to arrive at the predetermined coordinate point in three to ten minutes."

"Oh, well, how's the preparations on the ground going?"

"It's all ready, but the fuel sent up this time is probably only enough to maneuver back and forth three times. The space station has tried its best to reduce the speed of the space station, but the speed is still 7.02 kilometers per second, so short Can the time really guarantee the accuracy?"

"There is no chance, don't worry, no problem, after all, it is so far away, the angle of the laser is also calibrated in real time during the movement of the space station, it is like a hunter on a high-speed car extending the barrel from the window Just like aiming at a deer one kilometer away, as long as the hunter is experienced enough, he can also hit it with one hit, so please trust the real-time calculation and control capabilities of March."

"Alright then, Academician Ning, please take your time. I'll make a remote contact with the ground and ask if the equipment on the ground is ready."

"Well! Please cooperate with me, Professor Pang."

……

Of course, the test cannot be the same as the day it officially started. The equipment on the ground is a pole raised at the top of the honeycomb, and there is a sensor between the poles.In order to ensure that the pole will not shake slightly due to the wind speed, a fixing ring is installed near the top, and it is firmly fixed with eight heels of steel cables.

Half an hour passed in a flash, everything was ready, and the countdown began in the main control room...

The sky, which is running at high speed in space, is also passing over the capital at an extremely fast speed. During this process, the angle of the sky station began to be fine-tuned, and then maintained its posture. The bracket installed with the laser generator was almost indistinguishable to the naked eye. movement, adjusting the angle.

The sensor design on the ground is a ring with a diameter of about 10 cm, which is somewhat similar to the target used in Olympic shooting events. The difference is that there are not so many rings, but only three parts. The center of the circle is a small black circle with a diameter of only 1 cm. , the yellow part is the middle position with a diameter of 5CM except the black part, and the remaining part is white.

Lasers hitting different locations will generate different signals and be recorded, which will also determine the size of the torch switch that will be lit on the day of the Olympic opening ceremony...

As the time drew near, the atmosphere in the command center became more and more solemn, but everything outside was still peaceful.

Few people know that the most important ignition link of the opening ceremony is under active preparation. Of course, there are still some differences. For example, the Beijing traffic police department notified in advance the control notice on several main roads near the hive. The subway station near the hive is here. Time slots also temporarily stop docking.

These indirect costs are probably included in this unprecedented test, but because this test is during the day, most people in the world are unconscious.

No one knows at this moment, the space station like a speck of dust in space is passing by the sky above the capital at a speed of about 7 kilometers per second, and at this time, countless people in the master control center in charge of the laboratory are Staring at the screen nervously, the preparations that should be done have already been done, and there are not many things that can be done artificially, and they can only wait for the result.

"...5, 4, 3, 2, 1, 0, launch..."

The electronic synthesis sound echoed in the central control room. Two seconds later, the control center erupted with cheers and warm applause...

"Successful, successful, the system judged that the light source hit the bull's-eye!"

And by Ning Wei's side...

"Academician Ning, did it really work?!"

"Ning Dao, one-time success, this shot is too accurate!"

Finally, the countless cheers were interrupted by a meow...

"Meow……"

A Chinese pastoral cat suddenly appeared on the main screen, raised its head lazily and barked...

After the people in the control center were stunned, they immediately reacted, the applause remained the same, and the praise was rave.

"Good job in March!"

"It's already March, and it won't work if you change it."

"It's such a high speed to hit a moving target with one blow, and even an awesome character can't have this kind of reaction speed!"

"..."

……

"Huh... that's fine, I don't need a second test for this accuracy. The astronauts on the space station have worked hard, and they can return to the previous orbit. The ground preparations can continue as usual." Looking at the kitten on the screen, listening The excited and happy voices of the staff in the hall gave their opinions.

"Yes, yes, there is no need for a second test. It hit the bull's-eye, this accuracy... this accuracy... By the way, Academician Ning, can we read the entire background calculation process?"

"Of course, of course, Professor Pang, you only need to log in to the background, and all the data will be saved. I have seen the simulated data before, mainly because the conversion between the reference system and the coordinate system is more troublesome, and the amount of calculation involved is relatively large. Everything else is actually fine.”

"Thank you, Academician Ning."

"You're welcome, you're welcome!" Ning Wei Hao Ran said.

I am most afraid of such occasions...

The person in charge of the nearby control center immediately echoed, "Academician Ning, why don't you take this opportunity to say a few words to everyone?"

"Ah? What?"

"Just say something! You have also seen that everyone is so excited now, so you can just say a few words to everyone."

"Forget it, forget it... I still have something to do, I have to go back to school, I'll talk about it later when I have a chance."

"That can't be done. For a busy person like you, if you let go and come back next time, you don't know when it will be. Besides, you can see that everyone actually wants to hear something from you. Even if it is to encourage everyone to continue Let’s work hard in this direction.”

"Mr. Lu, I really have nothing to say." Ning Wei evaded again

It's just that this time Mr. Lu didn't give Ning Wei a chance, he just pressed the button next to him and picked up the microphone.

"Cough cough, everyone be quiet, let's listen to academician Ning Wei, who proposed the space station laser ignition project, tell us a few words, okay?"

Enthusiastic applause rang out again, and countless people turned their heads to look at Ning Wei on the highest podium. The person in charge of the nearby command center had already handed the microphone to Ning Wei.

……

Well, Ning Wei is really not prepared to say something today.

In fact, he has already planned the itinerary. After presiding over the test today, he will fly back to the capital and wait for the opening of the Olympic Games... After all, he is too lazy to continue wrangling with those big bosses, and the ability to speak in public is no longer enough. Degraded...

If possible, Ning Wei prefers to write small essays on Weibo, because it allows March to organize the copywriting...

So when the microphone was handed to his mouth, Ning Wei's brain was really blank...

Until a sudden inspiration flashed...

"Well, thank you all, let me tell you a story. It is said that when I was a senior student in Jiangcheng, one day because of something happened, I was in a very complicated mood, so I went to the famous Guiyuan Temple in Jiangcheng to relax. Coincidentally, that day I met a graduate student brother from the Department of Philosophy of Jiang University in Guiyuan Temple. He was ordained in Guiyuan Temple and became a glorious mage, but our encounter was a little different. You may not believe me, he You called me because you wanted to smoke, but you didn't bring a fire..."

------------

432 International Joke

It must be admitted that when a person is successful, any public speech can easily attract the attention of most people.And a successful person like Ning Wei is more convincing. After all, his life experience is no secret on the Internet, and he doesn't have a good father.

So although Ning Wei's tone of speech was not passionate and lacked the contagious power of a big guy, the story he told still got everyone involved...

"As you all know, there is no shortage of incense in temples, but my senior brother has principles and is unwilling to borrow the fire of the Buddha, and he doesn't want those senior brothers to see it, so I want to find a tourist to borrow a fire. It was such a coincidence that I happened to pass by that hall, and they stopped me, but unfortunately I don't smoke, and naturally I don't have the habit of carrying cigarettes with me."

"Coincidentally, that day was not a weekend, and there were not many people in the temple. At least there were no other tourists around my location. Fortunately, it was sunny that day, and everyone knows the weather in Jiangcheng. A sunny day in October has nothing to do with summer. So the brother went back to the main hall and found a magnifying glass, and asked me to light the cigarette for him with the magnifying glass."

"Look, is this a very troublesome thing? Not long ago, director Chen approached me, hoping that I could give some ideas to the opening ceremony of the Olympic Games. I don't know why, but I suddenly thought of this matter. Then there is today's This experiment. I just thought about it carefully, maybe subconsciously, I always think that every little advancement in technology should serve every ordinary person in this world, even if he is a smoker.”

"As scientific researchers, our goal is to make 100% efforts so that every Chinese can use the simplest method to solve some small troubles in life. Just like this time, we can use this Maybe in the near future, there will be hundreds or thousands of satellites carrying laser generators in low-earth orbit, which can provide real-time ignition services for every smoker who forgets to bring a lighter?"

"As long as you have a mobile phone, our March smart system plus the Beidou system, plus an APP, you can guide the brother who forgot to bring the lighter to a safe place that will not affect anyone else. When you light a cigarette, a laser beam will drop from the sky to solve the trouble of forgetting to bring a lighter..."

Everyone in the control center was dumbfounded at this time...

They thought that Ning Wei might tell an interesting story, but they probably never thought that this story could be so interesting, so interesting that they didn't know how to evaluate it.

how to say……

This probably belongs to the problem that can be solved by dividing the money evenly. A large plan of hundreds of billions of scientific research funds has been designed, which makes people feel outrageous when they think about it.

Fortunately, Ning Wei couldn't help herself and laughed out loud...

"Haha, lighting cigarettes with satellites is just a joke to everyone, but the idea I want to express remains the same. The progress of science is ultimately for the sake of human beings. Even if this demand is small, it is worth our [-]% effort. This sentence encourages everyone, and I also believe that our next generation, all Huaxia people in the future will remember the dedication of our researchers! Finally, thank you again for your hard work these days, allowing us to have a wonderful result today."

The speech is over.

In exchange for the wry smiles of the people around.

"Academician Ning, you really know how to joke!"

……

The space station of Huaxia in the sky has returned to its original orbit.

Of course, Huaxia Space Station's sudden move still attracted the attention of many people.

Especially the low-Earth orbit environment is already very complicated, mainly because there are too many satellites. In order not to cause accidents, the control center has already greeted the aerospace management departments of various countries in the world. Naturally, everyone will pay close attention to this time. action.

The principle of hypocrisy is always upheld in international exchanges.

No one really believes the reasons put on the table.

It's okay to do a track change performance test suddenly?Only ghosts really believe it.

A space station is no different than a satellite. Moving such a big thing in space costs money, and there is even a certain risk. Changing orbit just for the sake of changing orbit is really full.

Therefore, almost all the whole process of the space station's orbit change maneuver was recorded by interested people.

Although the naked eyes of people in broad daylight will definitely not notice the light falling from the sky, for many countries, the various devices on the satellite can still roughly judge what the Huaxia space station did in that short moment, It's just that this thing is done a little headlessly, which is very confusing...

For example, the US space agency, which is already very concerned about the Huaxia Space Station, and Maynard Jeffers, the NASA director in charge of monitoring, received the report almost immediately.

"What? The Chinese sent the space station there just to send a high-frequency laser into the capital? Then they returned to the original orbit? What are they trying to do? Long-distance laser weapons? Hit their capital?"

"It's not clear yet. But it is certain that this is not a weapon level. According to the results of the current analysis, well, in fact, it can be distinguished from this photo. The power of the laser emitted from the space station is not large, and after a long distance In particular, the attenuation and diffusion after entering the atmosphere do not have any power. Dr. Rosen suspects that this is testing a sophisticated laser positioning system, because this laser may carry specific wavelengths and information, so that it can track the ground Specific laser receivers respond."

"Precise positioning? Test in Huaxia capital?"

"It's really confusing, maybe you can call and ask..."

"Well, all right, you go to work first."

……

Watching his secretary walk out of the office, Maynard thought for a moment, then picked up the phone.

As the secretary said just now, NASA and Huaxia Aerospace Center have always maintained information communication.After all, everyone still has to argue about the space development plan every year.The universe is infinite, but the orbital space outside the earth is limited.There are too many satellites sent into the sky, and there is also the risk of traffic jams, and space resources are also resources.

Not to mention that satellites that are not affiliated to each other can change their orbits, and they may collide if they change orbits without communication. Especially for space powers like China and the United States, quarreling over orbital positions every year is normal.

Of course, if you want to quarrel, you still need channels, so we also left phone numbers with each other.However, who answers the phone is not very controllable. Whether you can find the person in charge sometimes depends on luck and the mood of the other party.

Maynard had good luck today. After the call was made, someone with enough weight quickly answered his call.

"Lu, we noticed that your country's space station actively changed its orbit today. You even installed a laser transmitter on the space station and launched it, so what is this doing? Don't lie to me with the test orbit change, old friend. Maybe I can be more honest now, otherwise I really don't know how to write the report."

When the call was transferred to his old acquaintance, Maynard asked straight to the point.

Although the words are very bachelor, it does not mean that Maynard will really believe that the other party will tell him the truth, but only shows an attitude that he has mastered everything. .In this way, even if the other party makes up nonsense to deal with him, it should be more reliable.

"Haha, Maynard, you are right. Of course, this operation is not only to test the space station's ability to change orbits, but you also said just now that we fired lasers. You know everything and you still want to ask me what to do? "

"What's the purpose? So you spent tens of millions or even hundreds of millions just to launch this laser?"

"You really want to know?"

"Of course!"

"Well, who made us friends. The situation is like this. Today, when a big man in our Huaxia wanted to smoke, he suddenly found that he forgot to bring a fire."
