Rebirth of science and technology academic master

"Academician Qin, is it true that the Tiangong space station will be decommissioned in 2032? The service time will not be extended!?" Yang Liwei couldn't help but ask.

The Tiangong space station, as the first space station built in China, and participated in the entire process, Yang Liwei and other astronauts have very deep feelings for the Tiangong space station.

"Well, the time has been determined, and it is set on December 31, 2032, when the Tiangong space station will crash in the Pacific Ocean." Qin Yuanqing nodded and said, this was a consensus reached at a space conference some time ago.

In that document, not only the detailed time for the decommissioning of the Tiangong space station and the specific location of the fall were determined in detail, but also some components of the Tiangong space station will be preserved as historical relics in the museum to continue to inspire the public. And this incentive effect will go far beyond the Tiangong space station itself.

To be honest, it is completely acceptable for Qin Yuanqing to retire the Tiangong space station, because the technology of the Tiangong space station was more than ten or twenty years ago, and now China's various technologies are exploding. With the improvement of the orientation, the technology of the Tiangong space station has fallen behind, and it is time to eliminate it, even if it is the only space station in the world currently in orbit.

And according to the plan, by that time, the scale of the completed part of the 'Double Ring Space Station' will be larger than the current 'Tiangong' space station. There is no doubt that by that time, the astronauts will go to the 'Double Ring Space Station', not the 'Double Ring Space Station' Tiangong' space station.

"Deputy Commander Yang, the decommissioning of the Tiangong space station is a foregone conclusion. In fact, no matter how much maintenance is done, it will not be able to maintain it for many more years." Qin Yuanqing seemed to know Yang Liwei's reluctance to leave the Tiangong space station and said with a smile: "It is a gratifying situation that aerospace is booming because each generation is getting stronger. This is true for astronauts and so is the space station!"

Yang Liwei sighed.

The Tiangong space station cost more than 50 billion yuan. It was built by China Aerospace Corporation through frugality and overcoming many difficulties. Although it is not as good as the International Space Station, it has its advantages.

And the most important thing is that this is China's first space station, which is of milestone significance. Once upon a time, China wanted to sell tickets with money, but was rejected without hesitation. From that time on, China was determined not to We should follow the path of independence, and we should develop our own manned spaceflight, our own global satellite navigation system, our own space station, and our own lunar exploration project.

The Tiangong space station is a milestone. Its completion represents that China has truly embarked on its own path in aerospace, and it is a correct path. It is a kind of pride and pride.

And now, unknowingly, the 'Tiangong' space station has entered the countdown to retirement, and this time point is exactly the same as Yang Liwei's official retirement time, which seems to make Yang Liwei always think that it is destined.

"How is this space environment simulation cabin used?" Qin Yuanqing asked.

Yang Liwei smiled at this time and said: "It is exactly the same as the space environment, and the weightlessness state is exactly the same. Everyone trains in it. Only when they go to space do they realize how much this training cabin helps them."

"When the 'Double Ring Space Station' is built, astronauts will not have to return to the ground in such a short time. It will be normal for them to work for a long time for one or two years. The facilities above are very comprehensive, and the living area is integrated with the ground. There is no difference, astronauts can exercise on it," Qin Yuanqing said.

The gravity of the living area of ​​the 'Double Ring Space Station' mainly comes from two parts. The most important thing is the centripetal force generated by the movement of the rings around the middle. One is the anti-gravity device. The anti-gravity device can provide anti-gravity, and naturally it can also provide gravity.

After spending a morning at the Astronaut Training Center, I returned home. The weather in July was already quite hot. The temperature in Beijing was as high as 33~35°C. However, in such hot weather, you could hear the bugle call. sound and zipper sound.

This is the military parade troops that are going to participate in the military parade undergoing training. This kind of training is very hard. After three or four months of training, the soldiers' clothes are worn out, their shoes are torn, and their hands have calluses. On average, Everyone has to lose 10 pounds.

But no one will complain about hardship and tiredness. Every soldier in the military parade consciously regards it as the most meaningful thing in his life and works harder than usual.

This National Day has attracted much attention, not only because it is another opportunity to show China's new style, but also this time, the main force of the military parade is the post-10s generation. Many young soldiers born in the 10s will represent the post-10s group and accept the people's review , officially took over the responsibility of protecting the country from his predecessors.

As the National Day gets closer and closer, the festive atmosphere of the National Day becomes more and more intense, so strong that you can feel it even if you close your eyes.

A small celebration every five years and a big celebration every ten years!

During this time, many people go out with their parents, grandparents, and travel to the capital to visit the Forbidden City Museum, the Summer Palace, the Old Summer Palace, the Temple of Heaven, and the Great Wall.

Through the car window, Qin Yuanqing felt the prosperity of this era. When the prosperous age came, it would not be an exaggeration to say that the house was not closed at night and people did not pick up things on the road. Entering the fourth industrial revolution, social productivity has been further improved, and materials are very abundant. Although it cannot be said that the fourth industrial revolution has been completed, no matter what, China has greatly increased its national power and strength, and its economy, culture, politics, science and technology, national defense, etc. have been greatly improved.

And all this is not over yet. China is still in the rising stage, and the speed of this rising stage is still quite fast. The annual GDP growth rate still maintains a high-speed growth, and this rapid growth can still be maintained for at least 10 years or even 20 years. Year.

"The lunar production base can also be put on the agenda!" Qin Yuanqing looked out the window at the busy traffic, looked at the red flags and Chinese knots hanging on the books, and murmured to himself.

The content of this last test flight of the 'Shenlong' aerospace aircraft is none other than the third manned landing on the moon. This manned landing on the moon is not only the establishment of China's third scientific research station on the moon, but also the establishment of China's third scientific research station on the moon. Three 1-kilometer primary runways will be built on the moon to prepare for the next manned lunar landing.

Unlike previous manned lunar landings, the third manned lunar landing will stay directly on the lunar surface for up to half a year.

The completion of this manned moon landing will also herald that Chinese astronauts will be stationed at the scientific research station for a long time to carry out various scientific research work. At the same time, it also means that the lunar production base will be officially put on the agenda. Some accessories of the "Double Ring Space Station" will be completed directly at the lunar production base, using the moon's low gravity to manufacture high-performance materials.

Back home, Qin Yuanqing entered the study, took out his notebook, picked up a pen and wrote on it. This is Qin Yuanqing's layout of the lunar production base, including mining sites, steel plants, aluminum plants, rare earth refineries, and helium. 3 refineries, etc., a total of 36 factories, dotted around the three scientific research stations.

The moon is 380,000 kilometers away from the earth. It is unrealistic to immigrate to the moon on a large scale in a short period of time. Therefore, most of them use robots and automated production, with a small number of engineers. Otherwise, there will be too many people, and oxygen, water, etc. alone will not be enough. question.

But if robots and automated production are used, then there will only be 200 or 300 engineers in 33 factories. This will undoubtedly greatly reduce the supply of materials from the earth and reduce production costs.

The "Golden Crow Device" has achieved a breakthrough in miniaturization, and the moon is not short of helium 3. This means that the "Golden Crow Device" can continuously generate electricity to supply the needs of the production base.

Qin Yuanqing pondered for a moment. This lunar production base is undoubtedly very important. Naturally, some defensive weapons always need to be deployed to protect the safety of the lunar production base. In this regard, defensive weapons such as laser cannons and particle cannons are needed. Installed, the energy shield is naturally needed.

"Perhaps in ten or twenty years, this lunar production base will evolve into a lunar base city. It is not impossible." Qin Yuanqing said in a low voice to himself.

It is an inevitable trend for the lunar production base to develop and become a lunar base city. Whether it is to open up fertile farmland, plantations, or develop tourism on the moon in the future, the lunar production base will gradually develop into a lunar base city.

It will also be a hub for traveling to the stars in the universe. It will be much more convenient to travel from the moon to Mars, Venus, Mercury and other planets than from the earth.

Of course, more importantly, the moon has enough resources, such as oxygen. In fact, the oxygen content of the lunar soil is 40%, which is enough to extract oxygen from the soil for use by astronauts and engineers, and can also be used as, for example, synthetic water. In addition, the lunar soil contains 14% aluminum and 4% iron, which can be easily mined. There is also lunar natural glass, which can be made into high-strength structural composite materials after physical treatment.

It is precisely for this reason that when the strategy was first formulated, Qin Yuanqing advocated the development of the moon and carried out manned landing on the moon. Rather than developing Mars and carrying out manned landings on Mars, as many people are keen on.

Of course, Qin Yuanqing also believes that the moon is another commanding height. As long as the moon is occupied and fully utilized, anyone who wants to go from the earth to Mars must obtain the consent of the CNSA, otherwise it can be easily intercepted.

To use a metaphor, traveling from the earth to Mars and other planets is a highway, and the moon is a toll station. As long as you occupy this place, you can let whichever car you want to pass, and you have to pay the highway toll. If you don't want any car to pass by, then don't let that car pass. You can't force your way in even if you want to.

Because you break in by force, you will be deducted points and your driver's license will be revoked directly. If you want to obtain a driver's license again, you must pass the re-examination and obtain the license.
