Earth Era

Comet Arthur is a sun-grazing comet, and the orbit of a sun-grazing comet has a characteristic, that is, the perihelion is very close, and the aphelion is very far. According to its original orbit around the sun, it will eventually pass just one million kilometers from the surface of the sun. Its sun-grazing speed will reach an astonishing 427 kilometers per second.

It is also this feature that makes it possible for mankind to change its orbit around the sun and change it from sweeping the sun to hitting the sun. Because its original perihelion is very close to the sun, humans do not need to change its orbit too much, just a little change is enough. If its perihelion is far away from the sun, even with all kinds of tricks, humans can't do anything about it.

But just this little orbital change has already made human civilization pay a huge price. Because the comet moves faster as it gets closer to the sun, the speed of Comet Arthur is already quite astonishing at the moment. Fortunately, the Lightbringer spacecraft was launched from a space base, so it could have enough speed to join Comet Arthur in space.

At the same time, the extremely high forward speed and extremely short time also mean that there is only one chance for human civilization. As long as this opportunity is missed, human civilization will no longer have the ability to change the orbit of Comet Arthur.

The entire mission process of the Light Messenger spacecraft adopts a live broadcast mode, and any human being can watch this grand event through various media. Zhao Huasheng is no exception, and even plasma lifeforms that do not belong to human civilization are no exception. It is also very concerned about this matter, but its state of mind watching the live broadcast is completely different from that of human civilization. Any human hopes that this mission will succeed, and plasma lifeforms hope that this mission will ultimately fail.

Under the gaze of all human eyes, the Lightbringer spacecraft finally crossed a long distance and came to a place only tens of thousands of kilometers away from Comet Arthur.

The Lightbringer spacecraft did not need to slow down after approaching Comet Arthur. Because Comet Arthur itself is moving at a very high speed, all the acceleration done by the Lightbringer spacecraft in the early stage is just to obtain the same speed as Comet Arthur, and then be in a relatively stationary state with it.

At this time, the Lightbringer II spacecraft set off, and the Lightbringer spacecraft that arrived earlier had already started work.

Through the video recording equipment installed on the spacecraft, all humans on earth have seen the true face of Comet Arthur. It was a chaotic, dark, icy, manic giant rock. There are countless small fragments surrounding the fifteen large fragments, running chaotically and colliding. When the sun shines on it, because of the unbalanced pressure, the gas deep in it will spew out, like a fountain, and spray into space like an explosion, blasting a large number of fragments away from the body like an explosion. While bringing more chaos, it also stretched out a huge comet tail.

The Lightbringer spacecraft watched the comet coldly from a distance of tens of thousands of kilometers. Compared with the comet nucleus, the environment here is quite calm, and even if there is an occasional impact of gravel, it will not have much impact on the spacecraft. Because both are moving at high speeds, the relative speed between them is not that fast. This level of impact is within the reach of the Lightbringer spacecraft.

Compared with this huge comet, the Lightbringer spacecraft is as insignificant as an ant. But that changed later. The solar reflector installed with the micro-engine was released from the spacecraft cabin, and then slowly unfolded under the impetus of the engine. So, when folded together, the little guy with a volume of only a few cubic meters at most has a surface area of ​​one square kilometer when unfolded. They perfectly reflect sunlight in other directions, and without sunlight, some parts of the surface of the comet's nucleus stop gasping immediately.

Not only that, some of the sunlight reflectors were also moved to a suitable position to reflect the sunlight that did not reach the comet's nucleus. As a result, these fragments are completely deprived of sunlight on one side, and on the other they get three times, even ten times, twenty times the original sunlight and heat. As a result, the gas eruption here has also increased to a dozen times the original intensity, and contributed a stronger driving force to the comet's nucleus.

All these processes are carried out under precise calculations. The mass, orbit, and ejection rate of these cometary nuclei are all under strict monitoring. All these changes will be collected and calculated by scientists, and the reflection angle of the solar reflector will be adjusted at any time according to changes in the situation. Where the solar radiation needs to be enhanced and where the solar radiation needs to be reduced, everything is being calculated.

This is the first stage of work. During this stage of work, human civilization will try to separate the fifteen large fragments from each other, with roughly the same orbits, but slightly adjusted in subtleties, in preparation for the next stage of work.

After the Lightbringer I spacecraft worked for seven days, the Lightbringer II spacecraft also came to Comet Arthur. The Lightbringer II spacecraft was larger and carried more supplies than the Lightbringer I spacecraft. After the first phase of work was completed and fifteen large fragments had been separated, the Comet Lander carried on the Lightbringer II spacecraft was released. They carried a large amount of fuel and were installed in different parts of each of the fifteen fragments, and then began to work under the instructions of ground operators.

So in addition to the solar reflector, these fragments also have a second power to change their orbits. Those high-equivalent engines sprayed long flame tails under the combustion of their own fuel, and because of the huge pressure, their heads plunged deeply into the body of the debris...

Although their thrust is huge, this level of thrust is still insignificant compared to huge debris with a mass of hundreds of millions of tons. Scientists have calculated that the thrust of all the engines combined is roughly equivalent to the thrust of an ant on an adult human body compared to the nucleus of a comet. But that's enough. First of all, this is the space environment, which is different from the ground environment. There is no such thing as air resistance here; secondly, the role of these engines is only for fine-tuning and precise calibration of the orbit, and the main task is still carried out by the solar reflector. .

Sunlight, the jet of gas inside the comet's nucleus, and the precise fine-tuning of the engine together constitute the force that changes the comet's orbit. This mission will last for two months. After two months, Comet Arthur will come only 15 million kilometers away from the sun. At that time, all human creations will be completely destroyed by the powerful power of the sun. destroy. Comet Arthur will embark on its journey to hit the sun alone.

Of course, before this moment, the fifteen fragments of Comet Arthur will have their own independent forward orbits. They will hit different parts of the sun as expected by humans, and then smash the reverse fusion layer and return the sun to its original face.

The comet impact program has been going well so far. This is not just a slogan, it is true, and the precise information obtained from the scientific research department can prove it. But the smoother the comet impact plan goes, the heavier Zhao Huasheng and the plasma lifeform will be. As for whether the reasons for the heavy hearts of the two are the same, it is unknown.

The two Lightbringers are still working next to Comet Arthur. Tens of thousands of scientists are still doing a lot of calculations and manipulations on the ground control base. At this time, another feast descended on the earth.

That is a meteor shower, a meteor shower so large and magnificent that it cannot be described in words.

These meteor showers come from Comet Arthur. The closest distance between Comet Arthur and the Earth is only 9 million kilometers. Although there is no possibility of the two colliding, the tail of Comet Arthur will stretch for more than 100 million kilometers due to the existence of the sun. Earth's orbit passes right through the tail of Comet Arthur.

The comet tail is composed of a large amount of interstellar dust and comet debris~www.novelmt.com~ When the earth passes through the comet tail, these debris will swarm into the earth due to the influence of the earth's gravity, and then die in the friction with the earth's atmosphere exhausted.

Tonight is a good time to watch the meteor shower. The sky is clear, there is no moon, and there is not much light interference. Zhao Huasheng left his home at this time and came to the small park near his home again.

There are already quite a lot of people in the park who are eager to watch the meteor shower. Zhao Huasheng didn't want to have too much contact with the crowd, so he came to a corner, sat on the ground against a bare tree with no branches and leaves, raised his head and looked at the sky quietly.

The night was very quiet, no noise, no disturbance. Zhao Huasheng was only accompanied by the faint night wind, the magnificent starry sky, and the occasional chirping of insects around him.

Zhao Huasheng's mind is very ethereal and distant. In this silent night, Zhao Huasheng thought of many things, Li Wei, Li Qi, Wang Tang, the head of state, Frank, and many, many people.

At this time, a soft female voice broke the silence: "Oh, what a coincidence, are you here too?"

Zhao Huasheng turned his head and saw Wang You walking beside him. She smiled gently, and then asked, "Are you also here to see the meteor shower?"

Zhao Huasheng nodded, and Wang You said, "Then let's go together, there are too many people there, it's too noisy, I don't like it."

Without waiting for Zhao Huasheng to refuse, Wang You came to Zhao Huasheng's side. Like Zhao Huasheng, he sat on the ground with his back against a small tree.
