Heavy Difficulties

Considering future maintenance, the habitation module adopts a modular suspension design. Each suspension module is equivalent to a 60-meter-high building.

At 2.8 meters per floor, a habitation module has 21 floors. With two households per floor, one module can accommodate 42 apartments.

If each apartment houses three people, then one habitation module can house 126 people. For over eighty-eight thousand people, approximately seven hundred and five habitation modules are needed.

Of course, it's not as simple as calculating three people per apartment, as there will be single occupants or rooms used for office space. However, the difference isn't significant; at most, nine hundred suspension modules should suffice.

In this design, each habitation module has a base area of approximately one hundred and eighty square meters. Each floor can be divided into two ninety-square-meter rooms or used as a single large space for purposes such as offices.

If so, then the height of the cylinder must be at least seventy meters.

However, in the design, Yue Yuan saw that the length of the spacecraft, which is the height of the cylinder, reached nine hundred and eighty meters.

Such a big difference! After listening carefully to the explanation, Yue Yuan understood that redundancy, the nuclear reactor, and various functional facilities had all been taken into account.

For example, the ecological cycle system, plantation, laboratory, and various material storage warehouses, etc.

Indeed, a residential spacecraft cannot only consider living space but also various supporting facilities and storage warehouses for machinery and equipment that humans might take with them in the future.

Yu Nanfeng continued his introduction.

Perhaps feeling that just talking wasn't convincing enough, he imported the data from the design plan into the computer and demonstrated the 3D model of the spacecraft to Yue Yuan in person.

Having a visual representation is definitely more realistic than just listening.

Yue Yuan looked at the computer screen, where a large cylinder marked with various values appeared. From the labeled values, it was easy to see that this was a cylindrical spacecraft with a radius of five hundred and fifty meters and a length of nine hundred and eighty meters.

Looking from the bottom, five thick force arms extended from the central axis of the spacecraft to the outer wall. Each force arm pulled a building base, and the building base was embedded with sixty-meter-high building suspension modules, resembling honeycombs embedded in a beehive.

Five force arms form a disc, and a one-hundred-meter-high cylinder is made up of ten such discs stacked together. Each disc has an independent power system to drive its rotation.

These power systems are actually super-large motors. Through the control system, ten super-large motors can drive the ten large turntables to rotate synchronously, or they can be combined into a super-large linkage motor to provide power for these ten large turntables that can be linked together at any time.

The nuclear reactor for energy supply is located in the center of the rotating shaft.

The core nuclear reactor is a very large facility, so the central axis that houses it is also designed as a towering pillar with a diameter of over two hundred meters.

The main thrusters are attached to the outer wall of the rotating shaft, the secondary thrusters are distributed on each force arm, and the vector steering thrusters are installed on the outer edges of the upper and lower bottom surfaces of the cylinder.

Looking at the detailed design plan, Yue Yuan nodded and said with satisfaction, "Use this plan. As for the multi-spacecraft plan, don't abandon it. Gao Kun, you are responsible for modifying it into a warship design. Later, I will have Pi Te arrange for relevant departments to cooperate. Strive to start the spacecraft project within this year."

"No problem, but if it's designed as a warship, I need the Command Department to cooperate!" Gao Kun responded.

"Of course." Yue Yuan said very simply.

After all, warships are for the Command Department, so the Command Department must be involved. Although they don't understand design, they can still offer opinions on usage habits, turret positions, and so on.

"Chief Yue, there's a problem." Seeing Yue Yuan get up to leave, Yu Nanfeng quickly spoke.

"Speak." Yue Yuan paused.

Yu Nanfeng hesitated for a moment and reminded, "Even if we build the spacecraft, we won't be able to leave Callisto immediately."

"I know, but we can't do nothing, can we?" Yue Yuan looked back and sighed.

Gan De had already mentioned the current state of space, with supernova remnants and interstellar dust everywhere. Spacecraft in the inertial navigation phase would definitely be slowed down by the dust. How could he not know?

However, if nothing is done, humanity may fall into a state of despair. Therefore, even knowing that using nuclear fission for propulsion makes interstellar travel difficult, they still have to do it.

Only in this way will those trapped on Callisto see hope and have a goal.

Moreover, it's not entirely hopeless. As long as controlled nuclear fusion is achieved during the construction of the spacecraft, that's possible. Although Callisto's technology has regressed compared to the previous Earth, it's not a huge gap. In the field of controlled nuclear fusion, it's only about a dozen years, and they are fully capable of catching up.

Coincidentally, the construction of the spacecraft also takes a long time.

According to the Engineering Department's estimate, such a large spacecraft project will take at least twenty years to build, unless technology takes off again during this period, otherwise it will take even longer.

After all, such a large ship is being built from scratch, and it also needs to be equipped with various facilities and nearly one hundred thousand Hibernation Pods.

In fact, there were some warships in Callisto's orbit, but they were all destroyed in the great disaster.

In short, start the project first. If nuclear fusion technology makes a breakthrough by then, replace the core nuclear fission reactor with a fusion reactor, and the thrusters as well.

If there's really no way, then we can only wait until the dust clouds in the supernova remnant are thin enough for interstellar travel.

"I understand. In that case, this plan needs to be adjusted. We need to reserve space for the power system installation and install it when the spacecraft is in the final stages of construction," Yu Nanfeng said, looking at the simulation on the screen. That was what he meant by asking Yue Yuan.

"By the way, do you have any ideas for the warship design?" Interrupted by Yu Nanfeng, Yue Yuan, who was about to walk out the door, suddenly changed his mind and turned back to look at Gao Kun.

"We on Callisto have experience building transport ships. Although the previous Space Dock has been destroyed, the technology is still there. I don't think there's a problem. The key is how big to make it," Gao Kun replied.

Yue Yuan said without hesitation, "It definitely has to be bigger than a transport ship, but it can't be too big. If you make something as big as a residential spaceship, we definitely won't have enough resources."

In fact, it's really not suitable for humans to build warships at this time, but without a single warship, Yue Yuan always felt uneasy. Even if he knew that if they really encountered aliens, it probably wouldn't be of any use.

"I think there's a problem!" At this time, Yu Nanfeng suddenly stood up from in front of the computer and objected, "Building a warship is fine, but how do we drive it away?"

How do we drive it away? Just follow the residential spaceship! Is there even a need to ask? Yue Yuan was about to say that, but suddenly realized the key point of Yu Nanfeng's objection.

That's right, how do we drive it away?!

We can't just let a group of people stay on the warship all the time. You have to know that it's a long journey. Interstellar travel requires hibernation for humans to cross that length of time.

Letting a group of people hibernate in a zero-gravity environment for decades or hundreds of years? That will definitely cause problems.

The reality is full of difficulties! But bare-bones sailing is too dangerous. Even if there are no aliens, encountering some other emergencies, at least we have a way to deal with them.

Without a few Atomic Bombs, Hydrogen Bombs, Helium-3 Bombs, and Neutron Bombs in hand, I really don't feel confident.
