Earth Era

The next day, Zhao Huasheng met the girl he had met yesterday again. It was just in the morning, and the sky was densely packed with star-like sun reflectors surrounding the slightly dim sun. Together with the sun, they brought warm air to the City of Life, and also made everyone in the City of Life feel warm. Plants grow. Zhao Huasheng was sitting on a stone bench in a small park, with his hands resting on the back of his head, leaning against the back of the chair, looking up at the sky quietly, not knowing what he was thinking.

At this moment, a soft female voice came into Zhao Huasheng's ears: "Hi, may I sit here?"

Zhao Huasheng withdrew his gaze to the sky, looked forward, and saw the girl he accidentally bumped into yesterday standing in front of him. The difference is that she has changed her outfit today, from professional attire to casual attire, but the quiet and calm aura on her body has not changed.

Zhao Huasheng didn't show too much attention to her, he just moved to the side, and said, "Yes."

Seeing Zhao Huasheng lower his head, the girl said with a little surprise: "Ah, what a coincidence, it turned out to be you. Didn't you go to work today?"

Zhao Huasheng looked at the sky again, and said lightly, "I don't have a job."

"No job?" The girl seemed a little puzzled, but didn't ask much. After sitting next to Zhao Huasheng, a pleasant smell, like a faint fragrance of flowers, entered Zhao Huasheng's nose. This made Zhao Huasheng frowned again.

"I was sick today and didn't go to work. It's too boring to be bored at home, so I went out for a walk. I didn't expect to meet you again. What a coincidence."

"Um."

"My name is Wang You, what's your name?"

"Um."

"Where do you live? You seem very heavy. What's on your mind?"

"Um."

"Oh, can you tell me what's on your mind?"

"Um."

No matter what the girl said, Zhao Huasheng always responded with a faint word. As if realizing that Zhao Huasheng didn't want to talk, the girl also fell silent, sat beside Zhao Huasheng, spread the book in her hand on her legs, and read it quietly.

This scene was also captured by a hidden camera, and then transmitted to a distance.

"Zhao Huasheng did not leave here, but chose to still sit here. I suggest that the contact index of No. 2 be raised to 80 points, the level is advanced, and the planning for the third contact should be started as soon as possible."

…………

Time passed quietly, about an hour or two later, the girl closed the book in her hand, then stood up, and said to Zhao Huasheng: "It's getting late, I'm going back, don't you go home?"

"Um."

"Then... goodbye. Thank you for spending the morning with me."

"Um."

Zhao Huasheng still put his hands on the back of his head and looked up at the sky, never looking at the girl. The girl waved at Zhao Huasheng, then turned and left.

Time is still passing peacefully. This area in the City of Life is like a paradise above the earth, no matter what changes from the outside world, it will not spread here. Zhao Huasheng's life is unprecedentedly leisurely and comfortable.

This kind of leisure and ease is not only reflected in the state of life. No matter where Zhao Huasheng went, Zhao Huasheng could always feel a faint warmth shrouding himself. Whether it's a smiling old lady you meet by chance, or a kid bouncing around with a lollipop in your hand, or a very beautiful young opposite sex who is very kind to you, Or a picnic of a group of energetic young people that I met by chance - in that encounter, Zhao Huasheng was just passing by, and was pulled into the party by a group of young people sitting on the ground, watching them sing and tell stories , drinking beer until drunk, laughing heartily... Although Zhao Huasheng has been watching quietly from the sidelines and did not participate in it, Zhao Huasheng can also appreciate their relaxation and joy.

Life just goes on like this. Zhao Huasheng is like a ghost walking in the world, watching all the beauty in the world with cold eyes, and then not being contaminated by any dust in the world.

Zhao Huasheng's countless people of all colors appeared in Zhao Huasheng's life circle, but none of these people caused ripples in Zhao Huasheng's heart.

Zhao Huasheng has also been following the progress of the comet impact project. For the sake of stabilizing people's hearts, improving self-confidence and cohesion, the human government has been publishing the details of the progress of the comet impact plan. Whether it is from the Internet or traditional media, Zhao Huasheng can obtain sufficient information.

Scientists first mobilized a huge force of observation, aimed countless telescopes at this comet that had never been taken seriously before, and even launched three detectors to observe next to Comet Arthur, one of which also came with a A lander landed directly on the largest fragment of Comet Arthur.

The scientists numbered the fifteen large fragments alphabetically, naming them Arthur A, Arthur B, and Arthur O. The scientists measured the size, mass, shape, gas content, elemental composition and other physical properties of these fifteen fragments in detail, and then performed precise and detailed calculations on Comet Arthur's orbit, gas injection rate and other data.

After obtaining these data, the scientists started the next step of calculation. Scientists divided the sun's surface into fifteen regions of different sizes, and then began to calculate which fragments should be used to hit which regions. After the deduction and calculation of this step also yielded the results, the scientists began to simulate the advancing trajectory of Comet Arthur fragments, and began to calculate how much engine thrust and gas injection rate should be used to make these fragments follow the calculated orbit. go ahead.

This is a very large and sophisticated calculation process, and this scale is the first time in human history. But humans have no choice. After all, this is the method with the least cost and the highest success rate in calculations. Therefore, human society must go all out to do this thing well.

Tens of thousands of scientists have participated in modeling and calculations, as well as mission planning. In addition, the construction of the "Skylab" space base has also been included in the work planning.

As the scientist said, it is not cost-effective to directly use a high-thrust conventional rocket that can only be used once to directly launch the solar reflector and engine to Comet Arthur. It is the most time-saving and labor-saving way to build a space base in orbit around the earth as a transit. The transportation of materials between Skylab and the ground is done by a new reusable rocket, and because Skylab itself is orbiting the earth at a very high speed, it does not require much propulsion to launch a rocket from it and too much fuel.

The entire human civilization has devoted itself to the preparatory work of Skylab with extremely high efficiency and enthusiasm. Skylab is based on the Beacon space station that existed in orbit around the Earth before, and has been refitted from a large amount of materials and equipment delivered later. Because it is not a new construction but only a modification and expansion, the construction of Skylab is extremely fast, and it has been completed in just two months.

There are two main reasons why such a huge construction project was completed in such an unbelievably short period of time. First, human science and technology have developed greatly compared to before, and second, human civilization has developed in this The most resources are invested in this matter.

After completion, the Skylab has a total length of 463 meters, a width of more than 200 meters, and a thickness of more than 30 meters. It is larger than the largest aircraft carrier on the earth. It is mainly composed of three living rooms, a space rocket launcher, and a large-scale material storage warehouse. Fifty-seven astronauts and engineers who have received strict training are stationed on the sky laboratory. With the command and assistance of the ground staff and the help of many automated equipment, they are responsible for the daily maintenance and daily launch of the laboratory. responsibilities of the task.

After the Skylab was completed, more and more intensive rocket launch missions were launched, and a huge amount of materials and equipment were transported to the Skylab. A new spaceship was assembled and received the name "Lightbringer".

This spacecraft will be launched directly above Skylab, and then it will dock with Comet Arthur after a five-day space journey. At that time, under the remote control of its own program and the ground control base personnel, Solar reflectors will be installed on top of the fifteen large fragments of Arthur's Comet, allowing those fragments to proceed according to the will of human civilization.

Spaceship launches in the space environment have completely different launch mechanisms than those on the ground. The spacecraft launched here does not need a huge rocket as a carrier. Here, the rocket is simplified into a very small detachable thruster, which will contribute enough to the Lightbringer spacecraft to break free from the gravity of the earth and accelerate. To the propulsion of extremely high speed, after completing its own mission, in order to reduce the total mass of the spacecraft, it will automatically detach from the spacecraft. After that, the fuel stored on the Lightbringer spacecraft will continue to accelerate it until it has the same speed as Comet Arthur and is in a relatively static state.

Two and a half months later, Comet Arthur is still 11 million kilometers away from the earth. At this time, the unmanned spacecraft Lightbringer was fully loaded with the materials needed for this mission, left the sky laboratory, and stepped into the vast space under the gaze of all human beings.
