Homo sapiens.

Including France, which is despised by netizens as a black-bone chicken, Great Britain, which is dying, and Lucia, whose science and technology rely on archaeology.

These forces have been "exploded" by netizens several times.

the other side.

On the official Twitter account of Space Exploration Corporation, there are also many yin and yang voices.

For example, some people say that Musk does not understand technology, and some say that the Starlink system is a space weapon in North America, and deliberately @Musk, let him land on Mars as soon as possible.

In terms of yin and yang, Dongying talents are the real kings.

Musk, who was at the headquarters of the Space Exploration Corporation, looked a little ugly looking at various comments on Twitter.

He quickly called several heads of technical departments to come to the office for a meeting.

One of the fat men said very distressed: "Recently, the Pentagon has repeatedly manipulated the Starlink satellites and tried to attack Homo sapiens' spacecraft, which caused us to lose a lot of satellites. If this continues, I am worried that Homo sapiens will directly attack the Starlink system." .”

Musk was also very embarrassed when he heard the words.

We must know that the success of the Starlink system is inseparable from the strong support of the US military. Without the support of the Pentagon, the space exploration company may go bankrupt because of this.

Musk thought for a while and ordered: "Launch a batch of more Starlink satellites to make up for recent losses."

"OK."

He looked at the person in charge of the Falcon project again: "Complete the improvement of the heavy-duty Falcon as soon as possible. I have a hunch that NSAS will definitely have a large amount of funding in the near future, and we will win part of the order."

"But the improvement of the Heavy Falcon is very difficult..."

But Musk is very tough: "I want to see a heavy-duty Falcon with a payload of 150 tons, otherwise it will be difficult to compete with other companies."

"I will try my best." The person in charge of the Falcon project was very helpless.

Chapter 4: Life on the Space Station

Homo sapiens space station.

After a day of assembly, the construction work was finally completed.

10 spaceships have become 10 space capsules, among which the node cabin and two power cabins are the core, forming the central axis.

The other 7 compartments are connected at two connection points of the node compartment.

At this time, Meng Haiyang and the maintenance officer Sakoshi Isao were floating inside the cabin, checking various areas.

Among them, the nuclear power cabin is the target of key inspection.

The nuclear reactor in this nuclear power cabin, due to technological innovation, is said to be a nuclear reactor, but it is actually more like a nuclear battery.

In order to reduce the accumulation of internal waste heat, the entire power generation system has prepared four layers of temperature difference power generation, which squeezes the heat energy emitted by the nuclear reactor to the extreme, achieving an extreme conversion efficiency of 99.99%.

In addition, the power generation system of this nuclear power cabin is also equipped with a liquid cooling system.

However, the liquid cooling system is connected to the liquid cooling water pipes in other cabins.

Although the internal nuclear power waste heat has been suppressed to a minimum, the heat energy brought by solar radiation cannot be ignored.

Therefore, such a set of liquid cooling system is set up. This set of liquid cooling system will concentrate the solar heat accumulated in the shell of the space station to the nuclear power cabin for supplementary power generation while taking into account cooling.

Through this liquid-cooled power generation hybrid system, it not only avoids the heat accumulation caused by solar radiation, but also provides an additional 0.3 megawatts of power generation power for the space station.

Of course, this power generation refers to when the space station is directly illuminated by the sun. If it is located in the shadow area of ​​the earth, then this power generation will be lost.

As for this part of the extra power generation, the way the space station handles it is to put this part of the power into the artificial magnetic field.

Because during the period of direct sunlight, the high-energy particles and cosmic rays in the Van Allen radiation belt will increase, and this part of the electricity can just be used to enhance the shielding strength of the artificial magnetic field.

The reason why the Van Allen radiation belt was chosen as the orbit of the space station was for safety.

After all, the dangers brought by the natural environment can be overcome.

But the darkness of the human heart is an unpredictable thing.

For the spacecraft of other forces, the Van Allen radiation belt is a forbidden area, but for Homo sapiens, it is a clean land.

Doesn’t it mean that the cost of protection has increased, and the range of the spacecraft has increased by 1200 kilometers. It doesn’t matter, Homo sapiens can afford this increase in cost.

If, like the International Space Station, the orbit is arranged in a 400-kilometer orbit, then it is not too simple for the Starlink satellites to come and touch porcelain.

When the satellite lowers its flight altitude, it is pushing the boat along the current, while flying to the Van Allen radiation belt is sailing against the current.

In addition, there are basically not many satellites in the orbit around the Van Allen radiation belt, and the magnetic field radar of the space station is very easy to find approaching targets.

If it is in a 400-kilometer orbit, with a large number of Starlink satellites and various other micro-satellites, the difficulty of monitoring has increased by an order of magnitude.

The Space Division of Homo sapiens is very clear that for some time to come, low-Earth orbit will become a space battlefield for all forces.

There is no need to risk yourself for a scientific research facility like the space station.

The Van Allen radiation belts instead serve as a protective layer for the Homo sapiens space station.

The Homo sapiens space department is already planning to occupy the inner area of ​​the entire Van Allen radiation belt in the future to suppress the entire low-Earth orbit.

Through the height advantage of the middle orbit, with a condescending attitude, it will occupy the height advantage in the future space confrontation.

At the same time, when flying in an orbit at an altitude of 1600 kilometers, there is basically no need to consider atmospheric resistance. The height of the space station can remain stable for a long time, and there is no need to regularly increase the orbital height like the International Space Station.

……

After Meng Haiyang and Sa Yuegong checked the nuclear power cabin, they confirmed that there was no problem, and then continued to the two power cabins.

The two power cabins are also the main power system of the entire space station, with 160 tons of methane and liquid oxygen stored on them.

Since it was only used once yesterday, the inspection is relatively simple, mainly to check whether the data of each sensor is normal or not.

After the two flew back to the node cabin, they saw Zhang Gongyu, the vice-captain who had come out of the experiment cabin, looking innovative and a psychological counselor.

Meng Haiyang asked, "Is there any problem with the experimental equipment?"

"no problem."

Meng Haiyang turned his head and asked with a smile, "Dr. Zhang, when do you plan to start the experiment?"

"Three days later! Let's get used to the environment first. After all, it's our first time in space, and we don't have as much experience as the space agencies of the great powers."

Zhang Gongyu is not only a psychological counselor, but also a material scientist. He worked in the 2331 laboratory of the Institute of Biomaterials before.

In fact, these astronauts are all elite new humans, specially selected for scientific experiments on the space station, and all of them are all-rounders.

In order to go to space, they also implanted some special bio-based armor.

It looks like you're wearing a space suit, but it's actually bio-based armor.

"Is there any abnormality in Jijia?"

Zhang Gongyu shook his head: "I haven't found it yet, and I need to observe it for a while."

Although this aerospace armor is specially designed for outer space, it doesn't mean everything will be fine.

After all, Homo sapiens has not engaged in manned spaceflight before, and even if the Ministry of Field Service "learned" the aerospace databases of major forces, it is still not 100% sure.

This is mainly because biotechnology is the core of Homo sapiens' technology tree, and other forces do not have such things as bio-based armor. There is no place to learn from in this regard, and Homo sapiens can only rely on Homo sapiens to explore a little bit.

Although the bio-based armor on the five astronauts has passed a lot of simulation experiments, the simulation experiments are not the real environment after all.

This is why Zhang Gongyu proposed to observe for three days before considering the experiment.

"Alert! Solar wind detected..."

Meng Haiyang hurriedly said, "Go back to the living cabin."

Everyone seemed to be swimming in the living cabin.

The functions of the two living cabins are actually not the same. For example, the living cabin 1 they entered at this time, this cabin is mainly used for sleeping, medical treatment, and driving.

The other living room—2 cabins is used for washing, catering and entertainment.

In fact, the node cabin can also hang a few sleeping bags, which can be used as a temporary rest cabin.

After everyone entered the living cabin, the cabin door was quickly and automatically locked. This is a requirement in the space work regulations, which is to ensure that each cabin is an independent airtight cabin during daily operations.

This is mainly to avoid a problem in one of the compartments and spread to other compartments.

Soon the solar wind reached the space station.

The magnetic cage defense system of the space station blocks most of the charged proton flow, while cosmic rays are blocked by the radiation protection layer of the outer shell, and the heat energy is brought to the nuclear power cabin by the liquid cooling cycle and converted into electrical energy.

Seventeen minutes later, this time the solar wind passed.

"David, report the situation."

"everything is normal!"

Everyone breathed a sigh of relief, blocking the test of the solar wind gave them a lot of peace of mind.

Even new human beings will feel fear and anxiety when facing this vast and boundless starry sky, which is an inevitable emotion for the unknown.

Only time can dilute everything.

After passing through this solar wind safely, everyone had a trace of confidence on their faces.

According to the needs of the garrison, Meng Haiyang began to divide into groups: "Chuangxin, Dr. Zhang, and David, you are in a group, and I am in a group with Sayue."

"no problem."

It is very necessary to take turns to be on duty, and there is no other way.

But even if you are on duty, you are not always busy for 12 hours. The company stipulates a 6-hour working system, which must be implemented. The rest of the time can be used for entertainment, or making phone calls with family members.

Chapter 4 Derivatives ([-])

8 month 22 day.

North Aerospace City of Motor Island Branch—in the 12th affiliated area.

Baisha, who is in charge of the design of the airship, is working in the airship manufacturing factory in this area.

In order to support the Dandelion project, not only hundreds of airship design engineers and researchers were gathered, but also an airship manufacturing plant was directly built locally.

Many huge scientific research projects often bring some derivatives.

For example, the Dandelion project in front of you.

Baisha's initial airship design was a helium airship, but as they improved, they even pointed out the cutting-edge technology of vacuum airship.

They used a new material called super-footballene, a by-product of another lab's work on carbon nanotubes.

Although there is no way to study ultra-long pure carbon nanotubes in an ideal state, it is possible to synthesize a two-dimensional carbon material, that is, a super-footballene material.

This material allows certain atomic-level defects to exist, and can make a spherical film with a radius of tens of meters, and the entire sphere is a molecule.

After the material is made into a sphere, it will form a special mechanical structure—an eggshell structure, which exhibits super resistance and rigidity when resisting uniform external pressure.

A carbon sphere of about one cubic meter can withstand a pressure of 17.375 tons, while a vacuum container of one cubic meter at sea level needs to withstand a pressure of about 10 tons.

This means the carbon spheres can be used on the ground.

Carbon spheres are very light, because carbon spheres are two-dimensional structures with only one layer of atoms.

Of course, since the molecules of carbon spheres present a honeycomb structure, air can pass through the gaps between the atoms.

In order to increase its airtightness, Baisha cooperated with that laboratory to study dislocation composite carbon spheres.

As long as 12 layers are superimposed and the honeycomb structure is misplaced, not only the airtightness can be guaranteed, but also the rigidity of the carbon sphere can be further improved.

In the assembly field in front of you.

Carbon spheres with a radius of 30 meters have been installed in the carbon fiber skeleton to form a ring-shaped airship with a radius of 3 kilometers.

At this time, the carbon sphere has not been evacuated, so the airship can still stay on the ground.

Once vacuumed, these carbon spheres with a volume of 20 billion cubic meters can generate 258 million tons of buoyancy, which is only available at a height near sea level.

For example, when flying to a height of 5 meters, the air density there is only 0.001 kilogram per cubic meter, and a vacuum of 2 million cubic meters can only provide 2000 tons of buoyancy.

However, the self-weight of the dandelion airship reaches 1430 tons. This is because the total weight of the carbon sphere is only 2.45 tons, and the lightweight high-strength carbon fiber skeleton is used.

整艘飞艇各个部件的重量中，碳纤维骨架1074吨、太阳能薄膜54吨、辅助推进器32吨、蓄电池40吨、真空碳球体24.5吨、抽真空设备47吨、电子设备和其他辅助设备181吨。

Only around 570 tons of payload remain.

So how does this weight support thousands of tons of hose?

The reason is very simple.
