Earth Era

Not many people know about this rocket launch mission, and even fewer people know the truth. There are only two people, one is the head of state and the other is Li Wei.

Only the two of them knew that the person riding in the rocket that just pierced the sky and set off from the earth to space carried the hope of the entire human civilization.

These billions of people, this land of more than 500 million square kilometers, the countless species living on the earth, and the future of the entire human civilization... are all tied to one person, Zhao Huasheng. Agreeing to cooperate with Zhao Huasheng's request and build a base for Zhao Huasheng on the moon was the most important move made by the head of state on behalf of human civilization. If this move is successful, human civilization can continue. If this move fails, the solar civilization will become the only civilization in the solar system.

Zhao Huasheng closed his eyes silently, his heart as calm as a pond on a summer night. Now that the plan has been carried out, there is nothing worth thinking about anymore. As long as you take the last step and lower the last flag, the war between human civilization and solar civilization will end. Of course, it’s still hard to tell who will be the final winner.

The rocket that is rapidly taking off is very noisy. The sound of gaseous fuel injection, the roaring sound of the engine, the sound of the friction between the rocket body and the air... all kinds of sounds were intertwined together, and when they reached Zhao Huasheng's ears, they turned into a strange and indistinguishable sound. A detailed buzz, like the sound of a car driving on the highway with the windows closed. Surrounded by this buzzing sound, Zhao Huasheng silently counted the time in his heart.

In just a few minutes, Zhao Huasheng suddenly felt his body relax. At this moment, the boulder that had been pressing on him disappeared. I can no longer feel any gravity. Then Zhao Huasheng knew that the acceleration phase was over, and at this moment, he had probably entered the orbit around the earth. Because he has reached the first cosmic speed, the earth's gravity can no longer restrain him, and he has become weightless.

However, because of the safety belt, Zhao Huasheng was still restrained on the seat. The three astronauts traveling with Zhao Huasheng unbuckled their seat belts. Floating in the air, he began to operate instruments one after another, and at the same time reported a series of data to the ground staff. from their conversations. Zhao Huasheng knew that what would greet him would be a connection with Sky Laboratory. A spacecraft will complete the task of sending itself and those supplies to the moon.

Space docking is a technically difficult and extremely precise task. To complete the space docking mission, not only the personal qualities of the astronauts are required, but the help of various advanced instruments is also essential. It is indeed very complicated, but if you look at it directly from the outside. It's surprisingly simple.

Above this orbit, Skylab and the launch capsule Zhao Huasheng is riding are orbiting the earth at a speed of more than seven kilometers per second. This speed is indeed very fast, but this is space, and the environment here is different from the ground environment. There is no reference here, so these two things look like they are stationary in space. So, after orbiting the earth four times and experiencing four sunrises and sunsets, Zhao Huasheng saw that the launch module began to approach the huge sky laboratory centimeter by centimeter. Finally connected with Skylab. After the pipes are connected, the buckles extend to fix the two together, and the docking is completed.

With the help of three other astronauts. Zhao Huasheng left the launch cabin and entered the sky laboratory. Skylab is much wider. It doesn't feel depressing at all here. The three accompanying astronauts stepped forward to hand over the mission to the remaining astronauts from Skylab, while Zhao Huasheng was floating aside without speaking, without any expression or movement.

The spacecraft is undergoing its final comprehensive inspection, which is expected to be completed by three o'clock tomorrow afternoon. So we need to stay in the sky laboratory for a day. An astronaut said to Zhao Huasheng. Zhao Huasheng nodded, indicating that he understood.

The astronaut continued: Your lounge is over there. If you are tired, you can take a rest. But please be careful, don't forget to wear your seat belt.

Zhao Huasheng nodded again and controlled the gas injection equipment to float into his lounge. Then he took off his spacesuit and put on something that was not much different from ordinary clothes. The spacesuit in the cabin was also soft and warm, and then he leaned in front of the window.

This is radiation-proof tempered glass made through a special process. Through it, you can see the vast and endless starry sky in the distance. You can also see the moon, which is much brighter than when it is above the earth. You can even see the moon clearly. the shadow above.

If you use your imagination, the shadows on the moon can make people think of many things. When human civilization was still in an era of ignorance, people already had many imaginations about this. For example, imagine a certain shadow area as a rabbit making medicine, imagine a certain shadow area as a big tree above the moon... and then extend it again, there is the story of Chang'e and Hou Yi, and the constant cutting down of trees, But Wu Gang was still unable to cut down the trees...

However, in fact, those are just caused by uneven terrain on the moon's surface and uneven sunlight exposure. It was lonely, cold, desolate and gloomy, and there was really nothing poetic or picturesque about it.

The yearning for the endless starry sky has always been deeply hidden in the mind of every human being, whether it is ancient people or modern people. The same is true for Zhao Huasheng. When he was young, when he looked up at the sky, Zhao Huasheng also had endless reveries in his mind. Now, the distance between Zhao Huasheng and his childhood dreamland is less than three days.

Skylab was still orbiting the earth at high speed, so a few hours later, Zhao Huasheng ushered in the first sunrise he could see in space. When Zhao Huasheng orbited the earth in a launch capsule before, he also experienced four sunrises and sunsets. However, the launch capsule was opaque and there was no transparent glass to allow outside light to enter Zhao Huasheng's eyes.

Sunrise in space is different from sunrise on earth. Here, the rising sun is not as gentle as it is on the earth. It had just been exposed a little, and it was already so dazzling that it was almost impossible to look straight at it. Because it is not covered by the atmosphere, there is no scattering effect. Although the sun has long been covered by an anti-fusion layer, and although the surface temperature has long dropped from 6,000 Kelvin to 4,500 Kelvin, the sun is still extremely powerful.

The Skylab itself is moving at high speed, so the sunrise process is much faster than on the earth. In just a few seconds, the sun completely jumped out from under the horizon, and then quickly reached the sky. So the solar power panels installed on the outer shell of the sky laboratory started their journey to chase the sun again like sunflowers. They changed their facing direction according to the changing angle of the sun, converting the sun's light and heat into The energy that humans can use supports the operation of the sky laboratory...

It's daytime in the usual sense of the word. But even during the day, the stars in the sky are clearly visible. No matter how powerful the sun is, without the help of its atmosphere, its luminosity cannot cover up the brilliance of the stars. So Zhao Huasheng saw the magical picture of stars and the sun coexisting. But Zhao Huasheng also knew that such beautiful scenery can only be seen with the eyes, and there is no way to record it with a camera or the like. The reason is simple. The brilliance of stars is too weak compared to the sun. The working principles of video or photography equipment are many different from those of the human eye. They must go through a long exposure to capture such a weak light. This is also the reason why many starry sky photos only have bright objects and cannot capture many stars, or the captured stars have long tails behind them. The reason why the long tails appear is actually because of the long exposure. In the process, the trajectories left by the movement of stars.

What appeared in front of Zhao Huasheng was a kind of beautiful scenery that could only be viewed but not preserved. Just like the happy time on earth, we can only cherish and recall it, but cannot touch it again.

The sun finally set again, and darkness fell again. Skylab also made some attitude adjustments during this period, so the window Zhao Huasheng faced was once again aimed at the starry sky and now aimed at the earth. So Zhao Huasheng saw the scenery above the earth for the first time from the posture of standing in space.

The prosperous earth in the past seemed like a dream. In that dream, standing in space and looking at the earth, even if it is night on the earth, countless lights in countless cities will embellish the earth under the night like a curtain studded with gems. But the earth is dark at the moment. Except for the equator, everything was pitch black and nothing could be seen, as if this place was still in a period of ignorance.

Only the equator is different. The brilliant lights are concentrated at the Earth's equator, like a bright belt surrounding the Earth.

Looking at the lights, Zhao Huasheng felt like a traveler who had traveled a long distance in the snowy night and then suddenly saw lights appearing in the distance. But Zhao Huasheng knew that he could never go back, never.

This separation from the earth will probably be forever. (To be continued ~^~)
