The speed of Arthur's progress is still increasing, and the long distance of 28 million kilometers only takes one day to cross it. Therefore, the two spacecraft of the Light can work for another half a day. After half a day, they will be burned under the scorching sun.

The two spacecrafts launched by human civilization naturally do not have the ability to accelerate to a speed comparable to Comet Arthur by relying solely on their own fuel and engines. But this doesn't matter, just like the famous "two iron balls land at the same time" phenomenon in the history of the earth. When the spacecraft i and ii have the same orbit as Comet Arthur, the sun's gravity accelerates Comet Arthur, and the acceleration rate is the same. Therefore, the spacecraft can maintain a relatively stationary state with Comet Arthur without consuming additional fuel.

The orbital adjustment work has reached the most critical moment. Because the distance is too far and the communication delay is too high, the ground control base has given up its control of the Messenger of Light spacecraft two days ago, and instead handed over the control authority to the Red Heart spacecraft. Five astronauts led by Captain Ragel are nervously manipulating the sunlight reflector plate to perform the final orbital calibration of Comet Arthur.

In order to prevent the strong thunder and solar storm that may be brought about by Comet Arthur's impact on the sun, the Crystal Heart spacecraft has already hidden behind Mercury and orbits the sun with the same orbital cycle as Mercury at a million kilometers away from Mercury. In this way, it can hide behind Mercury forever. No matter how violent the solar storm the impact of Comet Arthur will bring, Mercury will bear all of this for it. At the same time, because of its distance from Mercury and its gravitational slight gravity, the Crystal Heart spacecraft only needs to consume very little fuel to maintain its orbit and will not fall on Mercury.

The short-term control of the spacecraft of the Messenger of Light is the responsibility of the astronauts above the Red Heart, and the long-term control is still the responsibility of the ground control base. The three have been in contact and have never been cut off.

In the ground control base, the images of Comet Arthur and the images of the Messenger of Light spacecraft have been displayed on the big screen. Hundreds of scientific researchers and the commander-in-chief of the impact mission, Frank, are here. A large number of media reporters are also gathered here to broadcast all the situation here in real time to any corner of Equator City and the City of Life.

From the big screen, we can see that the gas burst above the comet nuclear debris on the comet Arthur comet has reached its most violent stage. Due to the increase in temperature and the increase in internal pressure, violent explosions occur all the time on the comet comet. After each explosion, gas like a fountain erupts from it. Under the huge power of the sun, the comet Arthur comet's comet stretches out hundreds of millions of kilometers in length. The sun's rays reflected by these comets can be seen even on the earth during the day.

It was the afternoon of the City of Life, and it was one of the most brighter periods of the day in the sun. But even so, when people looked up at the sun, they could still see the bright Comet Arthur.

Comet Arthur is right next to the sun, and even the sun's light cannot cover it up.

During the seven days of crossing the Earth's orbit and continuing to fly to the sun, every human on Earth witnessed with his own eyes how this comet, which carries the hopes and expectations of human civilization, became brighter step by step. At the beginning, only people with good eyesight can see it without light interference and excellent observation conditions. However, after just a few days, its brightness exceeded Sirius, the first bright star in the sky, and then its brightness exceeded Jupiter and Venus, and then its brightness began to chase the moon. At the last night when Arthur's Comet could be seen, its brightness had almost reached the level of the full moon. Even if there was no moon in the sky, Arthur's Comet could still shine brightly on the earth.

Then I can't see it at night. Because it is too close to the sun, it begins to rise and land with the sun. Its figure comes from night to day, shining on the world with the sun.

This is an astronomical wonder that is rare in thousands of years. Because of the special significance it carries, it quickly became the most famous comet in the earth's civilization. People know that two spacecraft of the Light Messenger are right next to Comet Arthur, and are working hard to adjust the forward orbit of this comet, which is extremely huge compared to humans...

Frank's name was also spread to the ears of every human on Earth with the name of Comet Arthur. As Frank wished, he is now the most well-known scientist in the earth's civilization. During this period, his fame even surpassed Zhao Huasheng. Under Frank's light, Zhao Huasheng was like a dim and inconspicuous star, and not many people would pay attention to him.

Frank knew that whether the comet impact plan could be successful and whether he could become the biggest hero in human history would be sentenced less than a day.

On this day, the entire Equator City fell into silence. Except for the necessary work, everyone stopped busy. Everyone returned home, stayed in front of the TV or other media, anxiously waiting for the results to appear. The busy Equator City stopped its always busy pace for the first time and entered stability and rest.

In addition to waiting for the comet impact to come out, there is another thing that forces people to give up their work and return home. That is the possible strong solar storm outbreak. Although the solar wind advances slowly, the speed of electromagnetic waves propagates at the speed of light. If after the impact occurs, the sun burst contains things like high-energy gamma rays, it is better to hide in the basement or indoors than to be exposed to the wild environment.

Zhao Huasheng also hid in the basement, and like other people, quietly guarded in front of the TV and watched the live broadcast of the Comet Impact Plan. The announcer's passionate voice kept echoing in the narrow basement: "The Comet Impact Plan has entered the most critical and final stage. The ground control base just received news from the Red Heart spacecraft. Captain Raggle has confirmed that the two spacecraft of the Light Messenger have been destroyed by the sun, and all sunlight reflectors, as well as the engine installed on the comet nuclear debris, were also destroyed in solar radiation and comet explosions. But Captain Raggle can also confirm that the fifteen comet nuclear debris have had suitable orbits, and they will hit different areas of the sun according to the wishes of our human civilization..."

"The sun is a sphere, but because fifteen comet nucleus fragments already have different orbits, they will hit different parts of the sun, including the back of the sun. The impact of these fifteen comet nucleus fragments will leave no blind spots, and they will enclose the entire sun within the impact range."

"Now, fifteen comet nuclei fragments are still a distance ranging from four to five million to the sun. The fragment numbered by Arthur Comet A is closest to the sun, and it will hit the sun in three hours. In fact, the distance of four million kilometers is already within the range of the sun's corona. Our solar observation satellite has observed traces of friction between the fragments of Arthur Comet and the corona... "

Zhao Huasheng climbed out of the basement and looked up at the sun. It was not beyond Zhao Huasheng's expectations. At this moment, Arthur's comet had disappeared and could no longer be seen. Although Arthur's comet had reached its highest brightness at this moment, it was too close to the sun, which made it impossible for it to see with the naked eye. It would hit the sun shortly afterwards and disappear from the universe forever from then on.

Zhao Huasheng looked at the sky in a daze for a while, and then returned to the basement again. Through live broadcast of the TV, Zhao Huasheng also saw the specially processed sun picture. Under the strong light of the sun, a very obvious thin line appeared. Zhao Huasheng knew that it was Comet Arthur.

At this moment, billions of tons of material are rushing towards the sun at a rapid speed. The mass of Comet Arthur's Comet is far greater than the original Moth Impact, and the impact speed of Comet Arthur is also far greater than that of the Moth Impact. Therefore, the influence of Comet Arthur will inevitably affect a much larger range than the number of three million square kilometers.

"What do you think at this time?" Zhao Huasheng asked.

The sound of plasma living organisms appeared in Zhao Huasheng's mind: "My thought is to destroy human civilization. If you ask me what I feel now... this feeling is probably like the feeling you saw countless humans being frozen to death."

Zhao Huasheng raised the corners of his mouth slightly, but said nothing.

Time is still slipping away bit by bit, and three hours pass by in a hurry. Frank's voice also spread throughout the city of Equator, throughout the city of life, and to all places where humans exist on the earth.

"If there is no accident, the fragment numbered by Arthur Comet A has hit the sun at this moment. Because of the signal delay, we must be about eight minutes before we can detect the changes caused by the sun due to the impact." Frank's voice was calm and steady: "Now, let's start waiting together. After eight minutes, everything will be revealed."
