Faced with a series of questions from Ni Pengcheng, Fang Cheng was not surprised. If there were no such questions, then Ni Pengcheng would not be qualified to be the chief engineer. Yan Bei also realized the difficulty, and frowned, waiting for Fang Cheng's answer explain.

Fang Cheng looked at the two of them and said, "General Manager Ni is right. If the current electromagnetic orbital launcher is used, what General Manager Ni said is indeed a problem."

"Before?" Ni Pengcheng and Yan Bei noticed this important word at the same time.

Fang Cheng nodded: "Our current electromagnetic orbital launcher is fully loaded with a load of [-] tons, and the launch and de-orbit speed can reach nine kilometers per second."

"This speed, in the past, can be said to be sufficient, and in terms of design, it is also sufficient to support our needs."

"However, for this asteroid, thirty tons and nine kilometers per second are a joke."

"According to its trajectory changes and gravitational wave measurements, its mass is about one trillion tons. In terms of this mass, it is almost three times that of the meteorite that destroyed the dinosaur era 500 million years ago."

"And we measure its size based on the spectral response."

"What is certain is that the main composition of this meteorite, excluding gaseous substances such as methane and ice, is more than [-]% iron-nickel metal."

"And its speed, 12 kilometers per hour, is more than three kilometers per second."

"Taken together, it can be seen that the kinetic energy carried by this meteorite is quite huge."

"One trillion tons is 300 billion times that of thirty tons, and its kinetic energy is 30 billion times that of our launch load."

"From the data point of view, our electromagnetic kinetic energy launcher, no matter what it launches, there is no other word to describe it except that the mantis' arm is like a car, and it is beyond its control."

"And 500 million years ago, the meteorite that destroyed the age of dinosaurs, at the moment it hit the earth, within [-] kilometers of the core store, it was wiped out."

"To this day, there is still a crater with a diameter of nearly [-] kilometers on the Yucatan Peninsula."

"The strong impact almost directly changed the earth's landscape. Volcanoes, earthquakes, and tsunamis filled the sky with dust. The long nuclear winter caused the mass extinction of life and the extinction of dinosaurs."

"And this time the meteorite is worse than last time. Do we really have the ability to change?"

"I can't guarantee it, but the chances are quite great." Fang Cheng said affirmatively, which made the two listeners even more confused and obviously more difficult. Then, where is the hope?

"First of all, the electromagnetic orbital launcher was originally only for launching into low-earth orbit, so the design goal is only to launch into low-earth orbit."

"Because the design goal only needs to achieve this goal, it saves a lot of cost. In essence, according to the design potential of this electromagnetic orbital launcher, it can continue to be lengthened, and the longer the orbit, the greater the kinetic energy it will carry! "

"According to my comprehensive calculations, after modification, the acceleration track can grow to ten kilometers in half a month." As soon as Fang Cheng finished talking about this data, Ni Pengcheng was the first to explode.

"Mr. Fang, can this electromagnetic orbital launcher continue to grow to ten kilometers?"

"This... can this really be done?" Ni Pengcheng asked excitedly.

Fang Cheng nodded: "Of course, on the Internet, don't netizens always joke that this is an interplanetary electromagnetic railgun?"

"Actually, this thing was originally in my design drawings, and it is indeed called a planetary-level electromagnetic rail defense gun. However, we didn't have this need at all before, and we didn't need it, so there is no need to use a longer orbit."

"At that time, it was just a redundant design space. I didn't expect that it is really used directly now."

"The designed track of ten kilometers is four times longer than two kilometers, and the increase in kinetic energy it brings is far more than four times."

"Of course, what's more important is the projectile."

"Hair can cut tofu."

"What will happen if our projectile, that is, the warhead, is strong enough and sharp enough, and the two collide head-on?" Fang Cheng asked.

"The strength is high enough and sharp enough?" Ni Pengcheng's eyes were full of hope, but his thinking was still rigorous enough: "If it is a rigid body collision, it is indeed possible to cause structural damage to the asteroid in a local area. So it breaks apart and becomes small pieces of meteorites."

"If the distance is far enough, it may even cause the direction of these meteorites broken by the collision to change, deviate from the orbit that hit the earth, and continue to fly towards the earth. Large targets can continue to strike. In this case, there is indeed a way to prevent this. part of a catastrophe."

"However, it must be hit by a rigid body. This is very difficult. According to the test data, it is not ruled out that the meteorite is covered with ice formed in gaseous states such as methane."

"If it wasn't for the rigid body collision, the effect would be extremely limited." Ni Pengcheng worried.

Yan Bei also thought about this problem and nodded in agreement: "This is indeed a problem."

Fang Cheng smiled: "Then remove the ice layer."

"You two, have you forgotten the plasma cannon we deployed on the star palace?"

"Compared to the surface, star palaces in synchronous orbit are more vulnerable to space debris."

"Moreover, facing asteroids in space is even more dangerous, so from the beginning of the design, there was a plasma main gun for outer space defense."

"Plasma-state propellants are fast and have a high rate of repeated firing. Although due to limited energy and distance issues, there is no way to melt the entire asteroid, but removing the ice layer on the surface of the asteroid should be no problem."

When Fang Cheng said this, every point that could be said hit the point.

Both Ni Pengcheng and Yanbei are experts in the industry, and their eyes gradually lit up: "If what Mr. Fang said can really be realized, then there is indeed hope."

"It's just that there is another problem. We have defensive weapons. This is only a solution to the problem. It is very difficult to hit the target under the condition of such a high-speed rotation of the earth."

"Just like my analogy, sitting on a merry-go-round, holding a gun to aim at the incoming bullets, it is too difficult to hit, let alone require many hits to complete the target."

Ni Pengcheng sighed. Speaking of this, Yan Bei, who was hopeful just now, was also discouraged at this time, "Yes, this is no different from the slingshot we are holding to shoot a plane."

Fang Cheng smiled when he heard the words: "Mr. Yan, what you said is too exaggerated. It's so primitive to shoot a plane with a slingshot."

"Our current Galaxy Future has the world's most advanced supercomputer, and the current Star Palace also has the world's most advanced radio telescope and the most accurate launch orbit calibration automatic system."

"It is undeniable that to launch an attack on an asteroid outside the Earth's rotation system on the earth that travels [-] miles a day, even if the model calculations are very accurate, but due to gravity, the rotation causes errors in the launch angle, We deviate a little bit when we launch, I am afraid that we will reach space, and as the orbit extends, the gap may reach thousands of miles, and there is nothing unusual about thousands of miles."

"The only way to solve this problem is to launch more while ensuring the accuracy of the launch. There is always a probability. It is better than sitting on the ground and waiting to die. As long as we do well enough, then the probability of hitting will be greater."

"In addition, compared with this probability of hitting the target, the most serious problem is the other problems that may arise if the target is really destroyed." Fang Cheng said emphatically.

"Other questions?" Ni Pengcheng and Yan Bei frowned one after another.

"The asteroid is so huge this time. According to my prediction, in order to actually hit the target, the distance must be close enough so that our error can be small enough and the probability of hitting the target will be higher."

"In other words, if we can crush this large asteroid, then it must be very close to the Earth's orbit."

"So, you two should understand what trouble I'm talking about." Fang Cheng said.

"Mr. Fang, are you saying that we are still likely to be attacked by a large number of small asteroids?" Ni Pengcheng asked with an ugly face.

Fang Cheng nodded: "This is inevitable."

"What we can guarantee is that before these fragments reach the atmosphere, the threatening targets will be crushed or become smaller."

"With the size of our star palace and the large number of plasma secondary cannons deployed on it, we can do our best to protect the airspace of our Xia Kingdom. We can only say our best."

"Of course, if we just rotated to the other side of the impact when we finally hit it, that would be a blessing in misfortune."

"Of course, the best result is that we can crush the asteroid enough, and all these fragments fall into the Pacific Ocean." Fang Cheng said, "But, everyone knows this, this is just a hypothesis."

After Fang Cheng finished speaking, several people in the video were silent.

Everyone looks forward to lucky things, but the future cannot be decided by luck.

Yanbei looked at the time, and then took a deep breath: "Consultant Fang, thank you for your valuable advice. I hope you will start the preparations as soon as possible."

"Whether you need it or not, prepare first."

"As for the large number of fragments at the end, I will report to the superiors. To put it bluntly, I am afraid that this kind of matter will not be passed until the last moment." Yan Bei said.

Fang Cheng nodded: "I know, so it's not a small trouble."

"However, I want to give you a deadline. Be prepared three days before the impact at the latest. Otherwise, you will have no chance."

"Three days?"

"I see." Yan Bei nodded.

……

About an hour later, this secret meeting in the international aerospace field was finally held.

Time was running out, and everything in the venue was kept simple. After a quick introduction by the host, the discussion on the emergency of the asteroid impact immediately began.

In such a big matter, at this time, to put it bluntly, there are only a few capable people in the space field, and the only ones with the most outstanding capabilities are Galaxy Future and Space Exploration Company.

But today, Fang Cheng did not speak, Ni Pengcheng did not speak, and Yan Bei did not speak.

Musk was a little surprised. Last night, he also didn't sleep, from fear, to excitement, and now to the little joy.Others saw destruction and fear, but what he saw was an opportunity, and he took advantage of this opportunity to crush Xinghe Future to death. He took advantage of this opportunity to make the Space Exploration Company right and become the strongest in the world. .

"Boss Fang, don't you want to say something?" Musk asked.

Hearing this, Fang Cheng looked at Ni Pengcheng who was standing aside, and Ni Pengcheng nodded.

They have already negotiated with the higher-ups, and the plan can be clearly stated, but whether to choose it now, whether to use it or not, is another matter.

In the face of this great crisis of life and death, the obstacles faced are far more than just asteroids.

Ni Pengcheng immediately stated the general plan of the plan, with some reservations, but the general meaning was that he made it clear.

After Ni Pengcheng finished speaking, there was sparse applause at the scene, but there was a rather piercing laughter.

"Sorry, I didn't mean to."

"I just wanted to say, is that all?"

"Galaxy Future is one of the outstanding representatives in the aerospace field in the world today. Whether it is a star palace, a plasma cannon, or the legendary planet-level electromagnetic railgun, they are all famous killers."

"As a result, the so-called solution can only be to break up large asteroids into smaller asteroids, and then let us each have our own destiny?"

"Do you not want to? Or don't want to? Or don't want to shoulder this responsibility?" Musk took the opportunity to attack, deliberately making things difficult, then shrugged his shoulders, and then showed an apologetic look: "Oh, I'm sorry, I'm so People talk too fast.”

"I didn't mean to be mocking, I was just surprised."

Hearing this, Fang Cheng laughed, "It's nothing surprising. We've tried our best. Everyone knows how difficult this asteroid is. It's a good wish to get through this crisis without any loss. I also hope it can be done, but after we have gone through the most scientific calculations, our plan can only do so much, and it can only do so.”

"Of course, this is the moment that determines the fate of all mankind. As a scientific research institution, it is our duty to put forward the plan, but whether to use it or not, whether to adopt it or not, is another matter."

"This requires a collective vote."

"What I want to declare is that we, Galaxy, will evaluate repeatedly in the future, and this is the only plan we are sure of."

"If Mr. Musk's space exploration company has a better plan, that's even better, and I can't wait for it."

"As long as this crisis can be solved, I very much look forward to a better solution." Fang Cheng said sincerely, with sharp words. The implication is not to attack each other's means, but to see the overall situation of human survival, calmness and magnanimity , making Musk’s target disappear invisible.

When Musk heard this, he snapped his fingers: "Hey, Mr. Fang is right, but you are right, our space exploration company really has a solution."

"Gentlemen and ladies, in this time of peril, what else is there to save the planet at this time?"

"At this most critical moment for mankind, the only person you can trust is Space Exploration Corporation!"

"There is only one answer, anti-gravity spacecraft!"

"To be exact, it's an anti-gravity spaceship full of nuclear bombs!"
