Although when the supply of meat was restored, in order to ensure that people's gastrointestinal problems would not occur, the supply of meat was limited, but in the past few days, major hospitals were still full. There are people everywhere with diarrhea and abdominal pain.
There is no way. I haven’t eaten so much meat in several years, so I ate more without noticing.
After solving the problem of food and meat, Cheng Xuanjia finally breathed a sigh of relief.
Seeing people all weak and emaciated, he felt uncomfortable. The most critical thing is that without adequate nutritional supplements, people will not have much strength or energy in the subsequent construction.
I cannot ask everyone to be like the original leader Zhao Changxing, who could eat starch paste and perform heavy physical labor at the same time. That's not realistic.
Now that this biggest problem is solved, the next step of construction can begin.
Therefore, in addition to those who had to stay in the Voyager spacecraft, such as teachers, minors, spacecraft maintenance personnel, etc., there were more than 28,000 people left, all of whom rushed to the front line of construction. .
Under the premise of increasing the degree of automation as much as possible and using robots to replace human labor as much as possible, people's construction activities have shown a momentum of rapid progress.
Railways appeared on the surface of Ganymede, factories rose from the ground, fusion power plants began to transmit electricity to the outside, and mining bases began to produce huge amounts of ore.
The steel plant spits out thick smoke day and night, countless trains run on the railway tracks, and many aerial and aerial spacecraft frequently shuttle between the spacecraft and the ground base. The originally desolate surface of Ganymede is a scene of prosperity.
Among all these constructions, the one that Cheng Xuanjia paid the most attention to was the construction of the No. 1 electromagnetic rail gun located in space.
Electromagnetic railguns can be located on the surface of the planet or in space. Anyway, their function is the same, which is to accelerate the standard resource box.
In Cheng Xuanjia's plan, the way the Jupiter system transports resources to Sedna is not like other dwarf planets, which send materials directly from the surface.
Jupiter is too far away from Sedna, so the standard resource boxes sent must be extremely fast. And this means that the power of the electromagnetic railgun must be as large as possible.
Moreover, in the later planning, all four Galileo satellites will usher in "land reclamation" and be integrated into the task of supplying resources to human civilization. Even in the further future, the remaining satellites smaller than Sedna will also be included in this system.
Maybe one day in the future, people will go directly deep into the atmosphere of Jupiter to mine resources.
If it were launched directly from the surface of the planet like other dwarf planets, then at least one electromagnetic railgun with such huge power would need to be built on each planet. Obviously this would create a huge waste.
So in the planning, Cheng Xuanjia decided to build No. 1, the main electromagnetic railgun, in space, and only build small and medium-sized electromagnetic railguns with lower power on the surface of the planet.
Therefore, the complete system will become like this: Whether it is Ganymede or other planets, the resources mined on all planets will first be launched to the resource transfer base through small and medium-sized electromagnetic rail guns, and then The No. 1 electromagnetic railgun here at the resource transfer base will then send them to Sedna.
With one more transfer node, the construction tasks are greatly reduced, but the efficiency is actually improved.
At this moment, it is too early to talk about the construction of the No. 1 main electromagnetic rail gun. This requires people to first complete the No. 2 electromagnetic rail gun located on the surface of Ganymede. Only after it is completed can it transport the building materials needed to build the main electromagnetic railgun into space.
This task was completed in the fourth year after arriving on Ganymede.
At this time, the supporting factories have almost been completed. Various mineral bases, steel plants, copper plants, foundries, precision processing plants, etc. are all in place. The construction of standard resource boxes is also on the right track.
As a result, standard resource boxes filled with supplies were launched into space one after another. Many space workers wearing spacesuits began processing and assembly directly in space. It took another four years to complete the construction of the main electromagnetic railgun.
This electromagnetic railgun is not so much an electromagnetic gun as it is a complete base.
It consists of three main parts in total. The first part is the material transfer center, which is mainly responsible for receiving standard resource boxes launched from other places and transferring them to the main electromagnetic railgun launch bay. The second part is a large fusion power plant.
The energy consumption of the main electromagnetic railgun is too high, and an extremely high-power fusion power plant must be built to support its operation.
The third part is the electromagnetic railgun itself.
These three parts are connected together to create this giant space base.
It's even longer than the Voyager spacecraft. The length of the Voyager spacecraft is 7 kilometers, and its length is a full 20 kilometers.
Of course, most of the 20 kilometers in length is the length of the electromagnetic railgun barrel.
Overall, its shape is like a long, straight strip extending from a big iron ball.
The material transfer center, fusion power plant, transit warehouse, personnel living area, etc. are all in the big iron ball.
At this moment, almost 9 years have passed since the Voyager spacecraft entered orbit. During these years, some people died unfortunately due to accidents, and some people suffered from diseases that even genetic modification machines could not do due to various disasters or their own reasons, and could only wait in the sanatorium area of the Voyager spacecraft. Even after death, many people found their lifelong lovers here and gave birth to the fruit of their love.
Some people came and some people left. The lives of people here in the Jupiter system and the lives of people on the Sedna planet inherently follow the same trajectory.
Just today, the development of the Jupiter system has reached a critical node.
Cheng Xuanjia has decided to send the first batch of supplies back to Sedna today, 17 years after he left Sedna and embarked on this voyage.
1,000 individual standard resource boxes with a total mass of 1,000 tons, each containing 850 tons of supplies, have been prepared and have been transferred to the launch bay of the main electromagnetic railgun base.
Among these materials, there are special steels, copper materials, water ice, chemical raw materials, gold and silver, and elements such as manganese, gallium, and indium.
The first standard resource box is sent.
Amidst the low humming sound, the speed of this standard resource box immediately began to increase. When it finally broke out of the 20-kilometer-long barrel, its speed had been increased to a high speed of up to 7 kilometers per second relative to Ganymede.
At the moment it rushed out of the barrel, the people in the main electromagnetic railgun base felt the base beneath their feet shake slightly.
The process of an electromagnetic railgun firing a standard resource box can also be compared to the process of a spacecraft engine injecting working fluid to provide itself with reverse thrust. The difference is that all electromagnetic railguns in the past were built on the surface of the planet. This force was "digested" by the huge planet and would not cause any visible impact on the outside world.
But this is space. No object can absorb this reverse thrust.
If no measures are taken, the electromagnetic railgun base that launches at a rate of one standard resource box every five seconds is equivalent to a spacecraft that ejects 1,000 tons of working fluid every five seconds. Sooner or later, it will be pushed away by this reverse thrust.
Therefore, people built a huge ion thruster in the "big iron ball" of the main electromagnetic railgun base, and started it all the time, applying acceleration to the base all the time.
In this way, the act of launching a standard resource box essentially achieves the effect of decelerating the base in this direction, while the ion thruster at the rear achieves the effect of acceleration. The effects of both sides cancel each other out, and the electromagnetic rail gun can be The base remains stable in the orbit of Ganymede for a long time.
It’s just the structural materials of the electromagnetic railgun base that suffer. They must withstand pressure from both directions at all times. If it cannot bear it, the entire base will be crushed.
Of course, people will always pay attention to the stress and pressure data on the main structure of the base to ensure that this kind of thing does not happen.
At this moment, the first standard resource box has been launched. 5 seconds later, the second standard resource box was also launched. Then the third, the fourth...
1,000 standard resource boxes with a total mass of 1 million tons took less than an hour and a half to launch.
This is just initial data that has not been debugged to the optimal state. When it matures in the future, people can even achieve the efficiency of launching a standard resource box every 1 second.
By that time, if it operates at full power in one day, it will be able to send a full 86.4 million tons of supplies.
No matter how you look at it, this is an extremely large amount of material. It is enough to support the development of human civilization.
At this moment, the standard resource box that left the electromagnetic railgun had acquired an initial speed of 7 kilometers per second.
Calculated at this speed, it would take about 70 years to reach the human civilization on Sedna from the Jupiter system.
This length of time is clearly unacceptable.
In fact, each standard resource box is equipped with 6 small ion thrusters, and it also has small fusion batteries and corresponding working fluids inside. Later, they will start to accelerate again and start to decelerate before reaching Sedna Star. Eventually, they can still park into the orbit of Sedna Star.
In this case, the entire voyage will be shortened to 20 years.
This length of time is probably acceptable.
At this moment, the people who had completed the first batch of launches were overjoyed and truly felt their contribution to civilization. But on the planet Sedna, which is more than 10 billion kilometers away, people are plunged into gloom and gloom.
