Silently opened the file bag, took out stacks of documents and explanatory notes, the Huaxia representative turned on the microphone, looked around at the polite smiles of everyone present, and then spoke, straight to the point, without any politeness.

"The problem of the Bell asteroid is very tricky, and if it were not for the reminder of the Chrono Review, human civilization would have been hit hard. Even if we have three months and a portal that allows us to go in and out of space at will, it will not be easy to solve this problem. ”

"Just now, Mr. Smith, the president of the Astronomical Union, has explained that the most difficult point in moving the orbit of the Bell asteroid is that its spin is very fast, and the centrifugal force has reached the critical value of its current mass. ”

"What's even more difficult is that it's loosely structured internally. Once damaged by external forces, it is very likely to lead to disintegration. It is unacceptable that we, the human race, will completely lose control over it. ”

Therefore, after detailed analysis, multi-faceted considerations, and research by many experts, we have planned the following plan. ”

As she spoke, the female representative opened the first page of the document and projected it on the big screen: "Please look at the big screen." ”

In the conference hall, everyone raised their heads and looked at the big screen seriously.

"The name of this scheme is called - reverse Yarkovsky. ”

The voice fell, and a suppressed whisper of discussion resounded in the hall.

Ignoring the crowd's talk, the delegate continued: "The Yarkovsky effect, in simple terms, is the small push on the star as an asteroid absorbs sunlight and releases heat. There are professionals here, so I won't go into too much detail. ”

"Your representative, I have a question. A blonde researcher raised his hand: "Are you trying to set up solar reflectors on an asteroid and let sunlight shine on the rock mass to reflect the kinetic energy of the thermal photons? But this method is too slow, and we are only three months away from us, so we don't have time to exert the power of this effect." ”

"That's why it's called reverse Yarkovsky. The female representative smiled: "The momentum of the thermal photon is too weak, so we don't need the momentum of the photon, we only need its heat." ”

"The main body of the scheme is as follows, erecting reflectors with a radius of more than 50 meters, focusing sunlight on the axis of the asteroid's spin, heating the rock mass, causing gas injection. ”

The crowd at the scene stopped talking, and many people picked up the computer and started to calculate.

"The continuous ejection of gas will bring continuous acceleration to the asteroid. After the analysis and calculation of our three teams, if everything goes well, three months later, the Bell asteroid will pass by the edge of the earth. This distance is 190,000 kilometers. ”

"190,000 km ......"

The moderator frowned and pondered, and after a moment, asked, "Has the Earth's gravitational pull been calculated, and have the parameters been corrected?"

"It's already counted. The female representative nodded: "Detailed data, my assistants will send it to your terminal." ”

The person in charge frowned deeper, stretched out his index finger and hit his head hard: "What about enhancement?

"Yes, look at the big screen. The female representative turned the second page of the document: "The most suitable enhancement plan is to unfold the solar reflector and match it with 130 laser emitters to fire lasers at a frequency of one-fifteenth of a second to enhance gas emissions when the structure of the Bell asteroid is stable." ”

"There are several other conventional heating methods, but they are not easy to control and have a chance to cause the asteroid to disintegrate. ”

After the words fell, the female representative spread her hands: "The only angle we can find is to push the asteroid forward, which is the safest and most stable way." As for the problem of being torn apart by gravity when Bell is close to the Earth, it cannot be avoided. We can only hope that the plan will work well and push it far enough. ”

"That's enough!" the person in charge stood up, his eyes blazing: "The spin problem of the Bell asteroid is too tricky, and it is not easy to push it down 90,000 kilometers away. But ......"

"But what?"

"Pure reflective heat energy is not large, you want to smear oil on an asteroid, right?"

"Yes, applying oil is the most important step. The female representative nodded: "Three days ago, we contacted Britannia Nano, and jointly developed a special paint with a light absorption rate of up to 99.965%, which is used to paint on the surface of asteroids. ”

"So......" The person in charge suddenly shook his hands: "We're going to make the time-lapse up master...... Going to paint?"

When the words fell, the conference hall suddenly fell silent.

The "......" female representative looked down at the document and corrected: "It's to paint a lot......"

……

"Lao Tzu is fully armed! lightsabers, protective suits, and almost removed the barrel of the island-building ship, but you told me to paint it?"

A week later, on the Purple Mountain Guanwentai Square, in the attention of more than 9 million spectators, Chen Yu looked at the person in charge in front of him, his face full of shock.

"I'm sorry, Mr. Wang. The middle-aged person in charge bowed again and again: "Due to the peculiarities of the Bell asteroid, it cannot be attacked with any weapon unless necessary." The asteroid's orbit can only be safely changed by pushing the rock mass by means of heating by the Yarkovsky effect. ”

"But ......" Chen Yu stretched out his hand, pointed to the oil drums piled up in the square, and roared: "This is too much, isn't it?

"The Bell asteroid is six kilometers in diameter and has a small area near its axis. The person in charge wiped the sweat from his forehead and stretched out two fingers: "You can brush two kilometers at most......"

Chen Yu: "......"

"Or... Or a little bit more......"

“…… Isn't there a very majestic plan like the plot of a hero movie?" Chen Yu stretched out his hands and tried to describe the picture in his mind: "Experiencing danger, hardship, hard work and wisdom, saving the world in the spotlight, cheering, shouting, applause, and flowers in your face, is there no plan?"

"No... There is no ......" The person in charge swallowed his saliva and said stubbornly: "You said it was a movie." Appear... In reality, it is only about efficiency and effectiveness. ”

[Hahaha laughing dead ヽ (≧?≦)?]

[I'm a stucco sauce, strong stucco skills?]

[At least hundreds of barrels of paint have been seen.] 】

[Distressed up master a femtosecond. 】

[Red fire roar hahaha......]

[I just learned that the diameter is six kilometers!

[It seems that the rotation is too fast to touch, otherwise it will disintegrate.] 】

[Bell: Touch me and try it? 】

[But painting is too sandy, isn't it?Is there really a way to intercept asteroids?]

[I haven't heard of it.] 】

[The plan formulated by professionals is definitely more effective than the media's fabrication.] 】

Turning his head and looking at the dense paint buckets, Chen Yu didn't give up: "Is there really no other plan?"

"Mr. Wang, no. ”

“……”

Three minutes later......

Chen Yu carried a large brush on his left shoulder and a paint bucket in his right hand, standing in front of the portal, refusing to take a step.

"Mr. Wang, time is pressing, let's start now. The person in charge took a large group of staff and experts and professors, and bowed: "We will deliver oil drums for you at this end." ”

"Made! this picture of saving the world is not epic at all......"

Cursing, Chen Yu stepped through the portal and rushed towards the gray-blue Bell asteroid......
