The "Shield of the Imperial Sky" is actually not An Chen's personal idea. Ever since humans realized that the Earth is a sphere covered with an atmosphere, the idea of breaking through the atmosphere has been around for a long time.

The ancients once conceived the idea of sending people to the sky with artillery battles, and at that time, people had realized that the fireworks launched could fly higher than the hornets, and the fireflowers could fly to the "heavenly court" that the hornets could not reach. But later, with the development of hot air balloons, people finally discovered that the place where the hornets flew higher was not the "heavenly court", but the outside world, where the air was getting thinner and thinner.

And the thin air is the key factor that restricts the flight altitude of the hornet.

In order to maintain high-speed flapping in flight, hornets are much more powerful than humans. Therefore, unlike most organisms, which rely on the decomposition of sugars to produce lactic acid, insects have evolved a unique reaction pathway called "respiration" in order to maintain the high consumption of flight, using the oxygen that is freely diffused into the body when the air sac is filled, and the oxidation of organic matter through a series of electron transport reactions, so as to obtain more energy than glycolysis alone. While for most other life on the planet, oxygen is just the waste of the metabolic activity of plants and many primitive bacteria, for wasps, oxygen makes up 53% of the volume of the atmosphere and is necessary for them to fly.

(Note: The biological setting here is significantly different from that of real-life life, in which the vast majority of animals obtain energy by aerobic respiration; Once again, comrades who do not know much about the concepts of basic science in reality, please read with caution so as not to mislead)

However, in addition to oxygen, what is more fatal for the hornets is the high air pressure and the decrease in temperature. In order to adapt to low atmospheric pressure and low temperature flight, the hornets had to increase the frequency of vibrating their wings, further increasing oxygen consumption. It's a vicious circle, so the Hornet itself can fly at a limit altitude of up to 9,000 meters, while in the case of a load rider, the current altitude record is only 5,347 meters.

The limitations of biology are doomed, and if you want to break through the atmosphere, you obviously can't rely on wasps. However, the special physiological structure of the wasp also gives people a revelation, it is probably impossible to fly by a reaction similar to glycolysis, the flight of the wasp relies on the greater power produced by the reaction of sugar and oxygen, and if you want to fly higher than the hornet, you need stronger "fuel" and "oxidant". As a result, with the deepening of human understanding of chemical reactions, more fuels and matching oxidants were invented, and the simultaneous development of Newtonian mechanics also made people realize that it was possible to rely on reaction force to "send me to the sky".

Finally, eighty years ago, the first idea of a modern rocket appeared. The man who came up with the idea, Tsiolkovsky Konstantin, was inspired by earlier science fiction literature for his idea of a rocket-propelled spacecraft, and he wrote about it in his science fiction novels.

(Note: Константин_Эдуардович_Циолковский is one of the three founders of modern cosmonauticism; After the October Revolution in reality, his living environment improved, and space research was also supported by the Soviet authorities, which may be one of the reasons for the rapid development of the Soviet space industry)

Konstantin also published papers that were recognized by the academic community, but at that time the theory of astronautics was not taken seriously by the imperial court. Just as airplanes are not valued, the vast majority of people always believe that wasps are enough, and that it is not worth developing a completely new technology simply to "fly higher". So, like the vast majority of depressed ordinary people, Konstantin was a private scholar who was close to deaf and completed his university courses on his own, with no degree, no family background, and no research direction, and he never received a position in the Imperial Academy of Sciences in his life. After publishing dozens of papers and more than a dozen science fiction novels based on his theories of astronautics, he ended up in his hometown as an ordinary retired high school teacher.

In fact, this is not much of a tragedy for the life of an ordinary person, but Konstantin could have received greater honors - if Anchen had been born fifty years earlier, he might have seen his theory become a reality before he died.

Of course, it was not uncommon for people to pay attention to Tsiolkovsky Konstantin's theories before Anchen. But those non-governmental non-profit organizations can only achieve the level of "enthusiasts" after all, and it is completely unattainable for commoners like An Chen to gather a group of second generations from aristocratic backgrounds, invest a lot of resources and energy, and really do it as a lifelong career.

The main industry of the bee kingdom was naturally monopolized by the Holy Lady and the Pope and various nobles. No matter what the industry, once its scale reaches the threshold of civilian self-management, its orderly operation must essentially rely on the appeal of α women's "miracles". The fact that a "miracle" could be a α female hormone, or a supernatural power of religion, or something else that is not yet known proves that a "miracle" – whatever it may be – is true.

But fortunately, the aerospace theory was finally noticed by An Chen, and she was able to muster enough strength to complete this matter.

The "Sky Shield" satellite network will enable real-time monitoring of every corner of the earth's surface, and it will help people understand the world they live in. At the same time, Anchen is also planning to send humans out of the atmosphere.

The unfortunate genius Konstantin once wrote in his article: "The earth is the cradle of mankind, but mankind cannot be bound to the cradle forever." It was this sentence that inspired An Chen to realize that the future journey of human civilization must be the vast universe beyond the atmosphere. The bee kingdom, which failed to break through the atmosphere and truly entered the universe, is the form of human civilization in the "cradle", and after leaving the cradle, human beings will enter the next stage of civilization.

Therefore, the "long-haul-3" rocket that Anchen is currently planning will transport a human passenger into space according to the plan. Experiments have been conducted in previous experiments to send dogs, and the reaction of dogs in space has proved that the space environment does not have a lethal effect on mammals. Therefore, it is acceptable to give it away.

As the satellite control group of the Sky Shield Space Division, the team actually led by An Chen is responsible for the "payload" part of the rocket. This part is also known as the functional part of the rocket, and the rest of the huge rockets of tens or hundreds of tons are essentially to send this functional area of less than five tons into the sky. For previous rockets, the payload was only a satellite, and the "long-distance-3" needed to carry an orbital module that could accommodate a person in space orbit for a short period of time, as well as a return capsule for sending people back to Earth and thrusters needed for landing.

In dog tests, the reliability of the existing orbital module, return module and thruster has been verified. But the point is that if you want to send people into space, you have to make sure that nothing goes wrong. And even if you can guarantee that nothing will go wrong, you still need to find a reliable astronaut who has the ability to take on scientific research tasks and the courage to step into the unknown.

An Chen actually felt that she should let her forget it. Anyway, it was her idea to engage in manned spaceflight, and she should be allowed to take risks. But this is obviously not realistic, An Chen is the only α female descendant of His Majesty Our Lady of Xinqi, the former Pope, and when An Jin's eggs stored in the palace's -80°C cold storage are exhausted, it is the day when she has to renew the human race. For this reason, Anchen must ensure her own safety, otherwise before human beings can really go out of the earth and into space, they will have to be spontaneously destroyed because of the decline in reproductive vitality.
