March 22.

The headquarters of the Earth Defense Council held its first meeting under the auspices of Qin Yongtu.

At the meeting, everyone was a little surprised that Jiang Bo became the chairman of the board of directors, but soon became accustomed to it.

No one dares to show contempt because he is handsome, because many plans will depend on his company to achieve them. He is now everyone's father.

The meeting initially determined the main positions of each department and a brief defense plan, and named the five asteroids as the "Fallen" asteroids. Resolving the asteroid crisis was a two-way "save plan" for the Fallen and the Earth.

Later, someone pointed out that it was necessary to observe the movements of the five fallen asteroids at all times and call the Sky-Survey Space Telescope (it seemed to have a name called New Horizon, I changed it).

Jiang Bo said there was no problem, and he had notified the nuclear-powered spacecraft to march towards the five fallen asteroids, and he would soon be able to observe them at close range and understand their composition.

The Superpowered nuclear-powered spacecraft, which is on mission above Mars orbit, received a new instruction two days ago to stop the patrol mission in Mars orbit, accelerate toward the five fallen asteroids with all their might, and observe their situation at all times.

Half a month later, on April 6, Overlord finally approached the first fallen asteroid. Through the videos and pictures taken by Overlord, experts from the Earth's Defense Council had a clearer understanding of the structure and material composition of the first asteroid.

On April 15, we have a preliminary understanding of the specific shapes and material composition of the five asteroids. The first four are metallic and the last one is rocky.

Regarding these five asteroids, experts have proposed more than a dozen ways to save the earth. Jiang Bo took the lead in proposing kinetic energy impact and net traction, but after discussion and calculation, only five were barely passed.

The first is to first launch a large number of high-density objects into space, and then use the engine to accelerate these objects. As long as 1,000 tons of objects are accelerated to 100 kilometers per second, that is, 360,000 kilometers per hour, you can obtain great kinetic energy, which is about 50 trillion joules of energy, that is, the power of 1.2 million tons of TNT explosives. If it acts sideways onto the asteroid, it will allow the asteroid to have a maximum speed of 1.5 kilometers per second in the side direction.

Of course, it will not actually exceed 500 meters per second (1800km/h), because during a collision, a large amount of kinetic energy will be converted into thermal energy, and the angle is also a big problem. However, in this way, the flight angle of the asteroid can indeed be changed.

For example, when a collision with an asteroid at a distance of 1 million kilometers, the asteroid has a speed of 1,800 kilometers per hour on the side. The asteroid rushed to the earth at a speed of 92,000 kilometers per hour. When it reaches the earth, the speed in the side direction has already caused the asteroid to travel 19,500 kilometers, while the diameter of the earth is less than 13,000 kilometers.

So at this time, the asteroid will be staggered from the earth, and the distance between the staggered distance is about 6,500 kilometers-19,500 kilometers. The speed of the asteroid is far exceeding the second cosmic speed, so it will not be captured due to the gravity of the earth. At this time, the asteroid will pass through the outer space of the earth and then fly towards the sun.

Of course, this is just a very ideal and simple computing model. The actual situation is much more complicated than this. However, if you can master the timing and angle of the collision, you can further the collision distance.

For example, when collisions are 5 million kilometers, 10 million kilometers, and 20 million kilometers away from the earth, the five asteroids can definitely pass by the earth and avoid collisions.

This solution is aimed at the four metal asteroids.

The second solution is to use a nuclear-powered spacecraft to cast a net for side-direction traction and use it in conjunction with kinetic energy weapons. It is technically feasible, but it is very difficult to operate. However, as long as it is successful, it can greatly ensure that the first four metal asteroids avoid collision with the earth.

The third type is conventional nuclear weapons. However, nuclear weapons have extremely limited power in space because they lose air power and no impact from airflow shock waves.

Therefore, experts from the Earth Defense Council are preparing to use large amounts of nuclear weapons to explode closely with the rocky asteroid with a diameter of 4.2 kilometers. In this way, the structure of the asteroid can be destroyed and split, turning it into many meteorites with a diameter of only a few dozen meters or even a few meters.

After entering the atmosphere, it will be disintegrated due to friction and heat generation. A small number of them cannot be disintegrated. As long as they do not fall into dense crowd areas, it doesn’t matter. Even if they fall into dense crowd areas, only by taking precautions in advance and using ground air defense systems to destroy them again can the asteroid crisis be perfectly resolved.

Although this will cause a large number of asteroid fragments to cause disaster to many satellites in the sky, it is better than letting the asteroid directly hit the earth.

As for the fourth type: install an engine on an asteroid, use a black bone nuclear-powered spacecraft to load the engine, and then quickly accelerate to approach the asteroid, maintaining an equal speed, and then install the engine to the side of the asteroid.

The fuel is specially treated and a large amount of liquid hydrogen and oxygen is mixed. Under the action of the engine, the combustion releases heat and jets to produce huge thrust. Although this thrust is not worth mentioning for asteroids with a mass of tens of millions of tons, there is always acceleration. As long as the time is enough, the orbital angle of the asteroid can always be offset.

The fifth type is to build an underground shelter as soon as possible. If the first two plans fail, there is no way. You can only hide in the underground shelter, wait for the impact, and then come out to clean up the mess.

Based on these five solutions, various departments of the Earth Defense Council began to mobilize resources and quickly operated.

As for other solutions, such as gravitational traction, stopping the earth from rotating, etc., these are not realistic. I won’t talk about gravitational traction. A spacecraft that is not that big or small-mass spacecraft will not work.

It is not realistic to let the earth stop rotating, because the losses caused are greater than those that asteroids hit the earth, and more people die, and the gain is not worth the loss. If you have that skill, it is better to just let the collision directly.

(The above is the information I originally prepared, and I thought about it and put it out. If I write science fiction articles in the future, I might pick them up and write them again.)

There are some below, wait until I post it slowly.
Chapter completed!
