Chapter 1136: space station

The first thousand sixty-four chapters space station
Zhao Zhongyao knew that as long as their astronauts completed the moon landing plan. When the astronauts personally flew to the moon and saw the huge stone pillar, maybe everything would come to light.
Political Commissar Yang heard what Zhao Zhongyao said, and he said anxiously: "How long will it take? How long will it take for our country's astronauts to reach the moon."
"This should be fast. Now we have completed the launch mission of the lunar rover. The next step is to start the construction of the space station. With the space station, we can carry out simulation experiments for the moon landing. I feel that within three years, we will be able to send our Chinese astronauts to the moon."
Zhao Zhongyao already had a plan. He knew that to complete the great plan of landing on the moon, the first thing to do was to build a space station. Of course, this space station can be just a small space station.
The current space station was built just for landing on the moon. After the successful moon landing in the future, the space station will be expanded several times. In this way, this space station can become a space research base, and many scientific experiments on the earth can be completed in space.
When I heard Zhao Zhongyao say that there are still three years left, the Political Commissar Yang is a little anxious again. He looked at Zhao Zhongyao and said, "It will take another three years, but it is really long! I want to know now, What are these two'things outside the sky'?"
Zhao Zhongyao listened to political commissar Yang, and then smiled again and said, "It is a bit anxious to wait until the moon landing to solve this mystery. But this is also a matter of no choice, this kind of thing. I am afraid that I will not know some secrets if I go to explore before now."
Zhao Zhongyao knew that if he wanted to unravel the secrets of these two huge ‘Things Beyond the Sky’, he would only find out after an on-site inspection.
"Zhongyao, isn't our lunar rover still on the moon? Then we will let the lunar rover look around, maybe we will see some magical things!"
Political Commissar Yang is very curious. He wants to know how many magical things there are on the moon.
Zhao Zhongyao heard what Political Commissar Yang said, and said with a smile: "Committee Yang, are you all on the moon as treasures! There are so many magical things. It is good that we can see two magical things."
"Zhongyao, no matter what, our lunar rover is still on the moon. Now that the lunar rover can work normally, why don't we continue to look at other places? Is there something magical? Maybe we can see Some things help us to unlock the secrets of the two'things outside the sky'."
Political Commissar Yang is very curious, and wants to see if there is anything magical on the surface of the moon and elsewhere.
After hearing what Political Commissar Yang said, Zhao Zhongyao smiled and said: "Haha, Political Commissar Yang, you really look like a child now! Okay! Since you still want the lunar rover to look elsewhere, then I will Command the lunar rover again and look around!"
After Zhao Zhongyao finished speaking, he gave instructions to the lunar rover, and the lunar rover began to drive on the moon again.
I just drove for a few more hours and wandered around a lot, but I couldn't see any magical things anymore.
"How about, Political Commissar Yang, there is nothing magical! Just these two things are already very magical. How many magical things do you want to see." Zhao Zhongyao looked at Political Commissar Yang again and said .
"Hey! There is really nothing magical." Political commissar Yang felt a little regretful. He originally thought that if it was a lunar rover, he could still see some magical things. Maybe, he could solve those two ‘spaces’. The secret of the thing'. But now it seems that if you want to unravel the secrets of these two ‘things outside the sky’, you have to wait at least three years later.
Zhao Zhongyao saw that Political Commissar Yang had some regrets, so he looked at him and comforted him: "Commissar Yang, don’t worry. We will begin construction of the space station soon. Once we build the space station, we will proceed. There have been many unmanned spacecraft landing experiments on the moon. At that time, we still have many opportunities to observe the surface of the moon. Maybe, then, we will be able to see some magical things again.
You have to know that our lunar rover has just landed in this place in'Jinghai'. The surface area of ​​the moon is very large. The range of a lunar rover is also limited. Only by launching a few more lunar rover can explore most of the lunar surface. "
Political Commissar Yang listened to Zhao Zhongyao's words, and then smiled again and said: "Haha, okay, let's start building the space station in the next step!"
In this way, after China completed the launch of the'Lunar II' mission, the next time it was to begin the construction of the'space station.'
Space station is also called space station, space station. It is a manned spacecraft that runs for a long time in low earth orbit, can be visited by multiple astronauts, and work and live for a long time. Space stations are divided into single-module space stations and multi-module space stations. A single-module space station can be launched into orbit by a space vehicle at a time, and a multi-module space station can be assembled by the space vehicle to send each module into orbit in batches. The space station requires all the facilities where people can live, and the space station does not have the ability to return to the earth.
The space station is characterized by a relatively large volume, a complex structure, a long orbital flight time, a variety of functions, and a wide range of space scientific research projects that can be carried out. One of the characteristics of the space station is economy.
For example, all space stations do not have the function of returning to the ground but accept astronauts in space for experiments, which can make the manned spacecraft a tool for transporting astronauts, thus simplifying the structure of the space station and reducing the difficulty of its engineering design. It can also reduce space costs.
In addition, the space station can be manned or not manned during operation. As long as the astronauts are started and debugged, it can work as usual, check regularly, and achieve results at that time. This can shorten the time of astronauts in space and reduce a lot of consumption. When the space station fails, it can be repaired and replaced in space, thereby extending the life of the spacecraft.
Increasing the usage period can also reduce space costs. Because the space station can fly for a long time (several months or years), it guarantees the continuity and in-depthness of space research work, which plays an important role in the gradual deepening of research and the improvement of scientific research quality. Zhao Zhongyao also knows something about the space station. After all, in the world before his death, there was already something like a space station.
It's just that there is no such thing as a space station in this world. In fact, the space station is a spaceship. It's just that this spacecraft doesn't need to return to the ground and stays in space forever, just like a satellite of the earth.
In fact, the space station is also a satellite of the earth, but this satellite is not used for observing the earth or for communication. It is a spacecraft that can carry astronauts for scientific research.
The main purpose of the space station that Zhao Zhongyao wants to build now is to land on the moon. After all, for China, the purpose of the current space program is to complete this great plan of landing on the moon.
To complete this great plan of landing on the moon, we must first build a space station in space. It should be said that in the world before Zhao Zhongyao was alive, when humans landed on the moon, they did not use a space station, but directly launched rockets from the ground to fly to the moon.
It’s just that Zhao Zhongyao knew that if that were the case, a lot of manpower, material resources and financial resources would be wasted. And he now knows that the humans in the world before his death paid a great price for landing on the moon. In fact, landing on the moon is a shortcut. It's just that the humans in the world before Zhao Zhongyao's death did not think of this when he first landed on the moon.
Now that Zhao Zhongyao is reborn into this parallel world, he also wants to help China complete this great moon landing plan, then he can choose a shortcut.
The shortcut is to build a space station first, and then complete the moon landing plan. In this way, it will be much easier. It will also save a lot of financial and material resources. After all, launching a rocket from the ground costs a lot of money every time.
And if you launch a spacecraft to the moon from a space station, you don’t need a high-thrust launch vehicle at all, just a small-thrust rocket.
This can save a lot of costs. Moreover, launching a spacecraft from a space station will also be much easier. You can launch a spacecraft directly to the moon without a launch window. When the spacecraft returns, it can also avoid the dangerous action of landing. Just fly to the vicinity of the space station first and dock with the space station. This will greatly reduce the risk of space exploration and provide a good guarantee for the safety of astronauts.
With this idea, Zhao Zhongyao also gave it to other researchers. And political commissar Yang and they had a conversation. Let them know one of their plans. After all, it is not an easy task to complete this great moon landing plan. It requires the cooperation of all parties to complete it!
Of course, Zhao Zhongyao is the chief designer of this space station. What kind of space station should be designed? This is also a question that Zhao Zhongyao has to consider now.
When he thought of designing a space station, Zhao Zhongyao's first thought was that the largest space station owned by mankind in the world before his death-the International Space Station.
Zhao Zhongyao also knows the International Space Station very well. He now wants to design a space station. First of all, he has to think about what the International Space Station in the world he knew was like and what kind of structure it adopted.
The overall design of the International Space Station adopts a truss-mounted cabin structure, that is, with a truss as the basic structure, the pressurized cabin and various other services are implemented on the truss to form a truss-mounted cabin-type space station. The overall layout is shown in the figure. On the whole, the International Space Station can be regarded as a three-dimensional cross combination of two major parts: one part is based on the Russian multi-functional cabin, through the docking cabin and node cabin, and Russian service cabin, experimental cabin, life support cabin, The American experimental module, the Japanese experimental module, and the ESA’s "Columbus" orbital facilities are docked to form the core part of the space station; the other part is on the truss structure of the United States, equipped with Canada’s teleoperation manipulator service system and the space station’s exterior Equipment, four pairs of large solar panels are installed at both ends of the truss. These two parts vertically intersect to form a "dragon skeleton", which not only strengthens the rigidity of the space station, but also facilitates the normal performance of various subsystems, scientific experimental equipment and instruments, and facilitates the assembly and maintenance of astronauts out of the cabin.
Now that Zhao Zhongyao wants to design a space station, he must first think about what the space station he knows is like.
Of course, the International Space Station is a later product. The first space station was not such a complicated structure. The earliest space station was just a space capsule and a docking station. In fact, it was a spacecraft that performed missions in space.
Such a space station is the earliest space station, a single-module space station, and the simplest space station. Only later, the space station grew bigger and bigger, and its structure became more and more complex. In the end, mankind built a super space station-the International Space Station.
Although Zhao Zhongyao also knows about the structure of the International Space Station, he knows that, with the current technology of China, he wants to build a super machine with a length of 70 to 80 meters, a width of more than 100 meters, and a mass of more than 40 tons. Space station, that is unlikely.
And Zhao Zhongyao also knows that the space station he wants to design now can only be a relatively simple space station. And the volume will not be very large. Just a very basic space station.
But Zhao Zhongyao knew that the space station he designed now must grow up slowly in the future. In this case, although this space station is small, it must have complete functions, and more interfaces must be designed on this space station. In this way, this space station will be able to continuously dock the space capsule like building blocks in the future, and then this space station will continue to grow.
Because Zhao Zhongyao knew that the great moon landing plan they were going to carry out, although it was a great one. But landing on the moon is not the purpose. The purpose of landing on the moon is only to explore space, and then make better use of space.
And the human space station is a facility for making good use of space. With such a high-tech facility, humans can conduct various scientific experiments in space. You can also make astronomical observations in space.
Space is a very clean and thorough place. Observing the starry sky in space is much better than on earth. Observing the starry sky in space, you can see many magical sights that are not visible on the earth. You can also see many magical celestial phenomena that are not visible on earth.
