Homo sapiens

Homo sapiens space station.

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

The 10 spaceships became 10 space capsules, with the node module and two power modules as the core, forming the central axis.

The other seven cabins are connected to the two connection points of the node cabin.

At this time, Meng Haiyang and maintenance officer Sha Yuegong were floating inside the cabin, inspecting various areas.

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

The nuclear reactor in this nuclear power cabin, due to technological innovation, is said to be a nuclear reactor, but in fact it is 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 to squeeze the heat energy emitted by the nuclear reactor to the extreme, reaching an ultimate 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 compartments.

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

Therefore, a liquid cooling system has been set up. This liquid cooling system will concentrate the solar heat accumulated in the outer shell of the space station into the nuclear power cabin to supplement power generation and take into account refrigeration at the same time.

This liquid-cooled power generation hybrid system not only avoids heat accumulation caused by solar radiation, but also provides an additional power generation power of about 0.3 megawatts to 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 space station handles this part of the electric energy by putting it into the artificial magnetic field.

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

The Van Allen radiation belts were originally chosen as the orbit of the space station for safety reasons.

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

The darkness in the human heart is something difficult to predict.

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

Isn’t it just that the cost of protection has increased and the range of the spacecraft has increased by 1,200 kilometers? It doesn’t matter. Homo sapiens can afford this increase in costs.

If, like the International Space Station, the operating orbit is arranged at a 400-kilometer orbit, it will not be too easy for the Starlink satellites to come over and make trouble.

When a satellite lowers its flight altitude, it is pushing the boat with the current, while flying to the Van Allen radiation belts is pushing the boat against the current.

In addition, there are few satellites in orbit around the Van Allen radiation belts, so it is very easy for the space station's magnetic field radar to detect approaching targets.

If it is in an orbit of 400 kilometers, the difficulty of monitoring a large number of Starlink satellites and various other micro-satellites will increase by an order of magnitude.

The Space Division of Homo Sapiens is very clear that in the future, low-Earth orbit will become a space battlefield for all forces.

For scientific research facilities like the space station, there is no need to put yourself at risk.

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

The Homo Sapiens Space Division is already planning to occupy the entire inner region of the Van Allen radiation belt in the future to achieve suppression of the entire low-Earth orbit.

Through the height advantage of the mid-level orbit, with a condescending attitude, it will occupy a height advantage in future space confrontations.

At the same time, when flying in an orbit at an altitude of 1,600 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 Sha Yuekong inspected the nuclear power cabin and confirmed that there were no problems, they continued to the two power cabins.

The two power cabins are also the main power systems 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.

After the two flew back to the node cabin, they saw deputy captain Mao Chuangxin and psychological counselor Zhang Gongyu coming out of the experimental cabin.

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

"no problem."

Meng Haiyang turned around 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, this is 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 materials scientist. He previously worked in Laboratory 2331 of the Institute of Biomaterials.

In fact, this group of astronauts are elite new humans, specially selected to conduct scientific experiments on the space station, and all of them are all-rounders.

In order to go into space, they also implanted some special biological armor.

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

"Are there any abnormalities in the base of the nail?"

Zhang Gongyu shook his head: "We haven't found anything yet. We still need to observe it for a while."

Although this kind of aerospace-type base armor is specially designed for outer space, it does not mean that everything will be fine.

After all, Homo sapiens has never engaged in manned spaceflight before. Even if the Field Service Department "learned" from the aerospace databases of major forces, it was still not 100% sure.

This is mainly because in the technology tree of Homo sapiens, biotechnology is the core, and other forces do not have such a thing as biological base armor. There is no place to learn from in this regard, and we can only rely on Homo sapiens to explore a little bit by themselves.

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

This is why Zhang Gongyu suggested observing for three days before considering conducting experiments.

"Alert! Solar wind detected..."

Meng Haiyang said quickly: "Return to the living cabin."

Everyone entered the living cabin like fish swimming one by one.

The functions of the two living cabins are actually different. For example, the living cabin they entered at this time - 1, this cabin is mainly used for sleeping, medical treatment, and driving.

The other living room - cabin 2, is used for washing, dining and entertainment.

In fact, the node cabin can also be hung with several sleeping bags and used as a temporary rest cabin.

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

This is mainly to prevent problems in one cabin from spreading to other cabins.

Soon the solar wind reaches the space station.

The magnetic cage defense system of the space station blocks most of the charged proton flow, while the cosmic rays are blocked by the radiation protection layer of the outer shell. The thermal 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, which made them feel at ease a lot.

Even new humans will feel fear and uneasiness when facing this vast starry sky. This is an inevitable emotion towards the unknown.

Only time can dilute everything.

After safely surviving this solar wind, everyone had a hint of confidence on their faces.

According to the needs of the garrison, Meng Haiyang began to divide into groups: "Innovation, Dr. Zhang, and David, you will be in a group, Sha Yue and I will be in a group."

"no problem."

Taking turns on duty is very necessary and there is no way around it.

However, even if you are on duty, you are not always busy for 12 hours. The company's 6-hour work system per day must be implemented. The remaining time can be used for entertainment, or making phone calls with family members.
