The outer space of the earth is now quite lively and prosperous, looking around, there are space farmland and space solar farms under intense construction, around the earth, there are now more than 300 space farmland, more than 50 solar farms are under construction.

An overhead plane constantly takes off from the ground and breaks through the atmosphere into space, they are loaded with materials and astronauts for the construction of space farmland and space solar farms, and slowly go to space farms and space solar farms.

After the materials are unloaded, they will go to the space farmlands to transport the grain, vegetables, fruits, etc. produced in the space farmlands back to the earth, and the business is very busy.

Huge space complexes, countless industrious little bee-like space planes, and from time to time you can see some old spaceships launched by rockets, etc., the whole space has the prototype of the interstellar age.

In the space city of Fuyun Group's "Sky City", Li Fu was wearing a spacesuit, and at this time, he was discussing something with Chen Bin and others looking at a huge space plane in space.

This time, Li Fu personally went to space to see the construction of the second generation of Fuyun Group's new aerospace aircraft, "Hercules."

The "Hercules" second-generation aerospace aircraft, to be precise, can no longer be called an aerospace aircraft, because it is not used to travel between space and the ground, but only used for spacecraft to fly in space, and it may be more appropriate to call it the "Hercules" second-generation spacecraft.

Hercules II was built from the ground up to adapt to the environment in space, it has no aerodynamic design, and it does not have the ability to enter the atmosphere at all, everything is designed around how to last longer, safer, faster and more powerful in the space universe.

Therefore, although all its parts are produced and designed on the ground, they must be assembled in space, and once assembled, it will always serve in space from beginning to end, and the most important role is to go to the asteroid belt to mine asteroids.

"Brother Fu, the second generation of 'Hercules' we designed and installed 2 ultra-high-power plasma engines as the main power, and installed 2 medium-sized plasma engines for reverse deceleration in the front and rear, and installed 2 small plasma engines for changing direction on the wings."

"Theoretically, it is enough to tow an asteroid with a mass of 10 million tons, and in addition, the endurance is enough for 2 years, which can fully ensure a trip back and forth to the small belt."

Chen Bin pointed to the second generation of "Hercules" outside the cabin and said, this "Hercules" second generation does not have the grace and vigor of the first generation of "Hercules", the overall look is more like a big fat man, the body is very huge, more than 200 meters long, more than 50 meters wide, and more than 50 meters high.

It can be clearly seen that there are two large plasma engines installed on both sides of it, as if it is the two big ears of an elephant, and the overall look is very huge, and the "Hercules" generation on the side seems to be a small point compared to it.

"The time to go to the asteroid is too long, even the nearest one is more than 1 astronomical unit, and the farther one has nearly 3 astronomical units, counting the round trip, that is, it takes 3 units to start, at least 500 million kilometers of long journey, such a long distance, the time to go back and forth is very long."

"Therefore, in the material area, it must be sufficient, and I think it can add a pair of wings to the energy part, and use solar energy as much as possible to get more energy and more security."

Li Fu looked at the huge "Hercules" second generation in front of him, and thought carefully in his mind, the asteroid belt is not the moon, and it is a long journey calculated with hundreds of millions of kilometers casually, and there are strict requirements for the continuous working ability of the spacecraft, the consumption of energy, the consumption of materials, and so on.

It is necessary to carefully calculate every link, and make careful calculations to ensure that there will be no problems with energy and materials, only when the problems of materials and energy are guaranteed, astronauts who go to mine asteroids can settle down, otherwise absolutely no one will be willing to work for you.

"I didn't think about it, but luckily I just added solar panels, and I didn't have much work."

Chen Bin nodded after listening, although the spacecraft cannot go back and forth between space and the ground, but there are many advantages that aerospace aircraft do not have, first of all, there is no need to consider aerodynamics in the design, the shape and so on can be designed at will, it is very easy to add some things, and it will definitely not say that there is much impact.

"In addition, astronauts fly in space for a long time, they must take into account physical exercise, all kinds of fitness equipment for exercising are absolutely indispensable, and it is best to have a crop planting area, you can grow some crops yourself, add some green life to the spacecraft, so that the anxiety caused by the astronauts who have been off the ground for a long time can be greatly alleviated."

Because it was the first time to make such a long flight, everyone also crossed the river by feeling the stones, and they had little experience, but Li Fu analyzed it with reference to the early development history of the super civilization Han Science and Technology Empire, and learned some experience from it.

"Crop growing areas?"

Chen Bin naturally didn't understand why Li Fu suddenly said that he wanted to add this, so his mind was full of questions.

"Well, according to research, long-term spending in space can make people feel restless and negative, and once this emotion accumulates, it is easy to make astronauts impulsive, anxious, and even temperamental, as has happened on the International Space Station in the past."

"Astronauts who have been in space for a long time fight each other over some trivial things, and almost end up causing a tragedy, not because of the quality of astronauts, but because of the problems that will arise when they stay in space for a long time."

"So build a plant planting area, and the anxious astronauts can go to the plant planting area to relax and relieve this emotion."

Li Fu explained with a smile, in fact, this symptom is called void syndrome in the professional terms of civilization seeds, but the earth has only just entered space, and this kind of problem has not been encountered at all, and no one has studied and understood it in depth.

"I mean, when I stay in space for a long time, I always feel more irritable and anxious, and I can only feel comfortable when I go back to the ground and sleep for one night, so that's the case."

Luo Xiaoyao, who was on the side, listened to Li Fu's words and suddenly said.

"Well, I'm going to have the interior design revised."

Chen Bin nodded solemnly after listening, the most important thing in space is actually people, scientists, engineers, astronauts, etc., only by ensuring everything for them can we talk about anything else.

The huge second generation of "Hercules" is quietly moored in the space port of the "Space City", and the mechanical arms are constantly busy.

On either side of its large, fat body, the robotic arms are constantly busy, and they are installing solar wings to increase its endurance and replenish energy during long journeys.

Flying in space, although the time is basically based on inertial flight, basically no energy is consumed, but the energy consumed in the acceleration and deceleration phases is enough to account for more than 90% of the total energy consumption, and it is necessary to maintain the needs of at least several astronauts during the long journey, so the energy problem is also a very important issue.

A pair of huge wings with a length of more than 200 meters and a width of more than 50 meters were installed, and at this time they were still in a folded state, and once they were installed, the wings slowly unfolded.

"It looks more like a Dumbo, a winged Dumbo, fat and big."

Zhanfei looked at its overall appearance and couldn't help laughing, the design of the second generation of "Hercules" did not consider aesthetics at all, so it looks really fat and fat, and now it has a pair of wings, a proper Dumbo.

"Dumbo? It's a fitting name. ”

Chen Bin touched his chin, looked at the huge second generation of "Hercules", and nodded in agreement.

Dumbo's interior, the entire interior is a honeycomb structure, the center of a room can lead to a separate room, each room has its own independent life support system, of course, the function of each room is completely different.

There is a cab for driving and controlling the aircraft, located at the front; There is a food storage room, which is also the most important cabin to store enough food for astronauts to eat for more than 1 year; There are also energy pods, which are located on each side and are used to provide enough energy to the ship......

In addition to these conventional, the second generation of "Hercules" also carries two small spacecraft, on the one hand, it can be used for emergency escape, in the event of a major accident, astronauts can take two small spacecraft for emergency escape; Another role is to assist in the mining of asteroids, to explore the situation of asteroids, to help release the rope that drags asteroids, and so on.

Of course, Li Fu also applied to the above, and after obtaining permission, he equipped it with some weapon systems, a few missiles can be used to destroy large asteroids that collide, and the rail cannon relies on the brutal impact force to destroy small and medium-sized asteroids, and it also has great destructive power for large asteroids.

To go to the asteroid belt to mine asteroids, its power system, communication system, life support system, circulation system, etc. are all tempered, almost representing the most pinnacle technology of Fuyun Group, although it looks ugly on the outside, but its technical content is definitely the highest among all the aircraft in space, which can represent the crystallization of the current peak technology of mankind.
