If we plan according to the worst-case scenario, that is, if everyone takes refuge in the Spark spacecraft, we first need to determine what kind of supplies should be brought aboard.
The first thing that was identified was food.
All kinds of grain, meat, eggs, and vegetables must be brought into the spacecraft.
At this moment, there is still about half a year before the arrival of the asteroid. During this time, it is enough for the crops in the planting workshop to grow to maturity, harvest, and then sow again. Plus the materials previously stored in the warehouse, it is enough to
It's almost enough to feed everyone today for more than a year.
Of course, this is under the premise of implementing wartime controls and strictly controlling intake.
"Then, from now on, wartime controls will be implemented, and everyone will be allocated food at regular times and rations every day."
Zhao Changxing gave the order without hesitation.
After the disaster, no one knows when food production capacity can be restored. In this case, of course, the support period must be extended as much as possible.
People nodded silently.
"The various living supplies in the Spark spacecraft, especially water, must be replenished in advance."
The status of water is very important. Not to mention drinking, after electrolysis, hydrogen can be used as fusion fuel, and oxygen can be used for breathing. The status of water is even more important than the status of food.
This article was also passed.
"After that, there are all kinds of equipment that cannot be manufactured at this stage. Fusion generators, chips, 3D printers, and precision machinery."
"If there is still room in the Spark spacecraft, then bring a machine that requires more energy and resources and is more difficult to manufacture."
…
During people's discussions, a long list of items was quickly generated.
According to the overall plan, before the disaster strikes, people should take various supplies and hide in the spacecraft in advance, and then make do in the crowded spaceship for about a month, waiting for the disaster to completely subside and for the restless Seid
Sedna returns to calm - in fact, the time it takes for Sedna to completely return to calm is probably measured in hundreds of years, but people obviously can't wait that long. Generally speaking, once calm is restored, they have to hurry down and start moving forward to the next step.
, otherwise everyone will starve to death.
When they can land on Sedna, people must start building planting bases as quickly as possible and go all out to restore food production, and this must be completed within a year. After all, people still need to leave time for crops to grow.
.
During this period of time, everyone still has to return to the Spark spacecraft to spend their rest time. Because it is obvious that there will be no place for people to rest on Sedna.
If everything goes well, the new planting workshop can barely take on the responsibility of supplying food before the food reserves are exhausted. Only with a continuous supply of food can we discuss the next arrangements.
However... no one is sure whether it is possible to build a planting base with a total area of at least 5,000 square meters in one year in the process of almost overturning everything.
This time, there won't be enough modular building materials for people to use.
"Let's dismantle the No. 2 Comprehensive Base first." Zhao Changxing made arrangements loudly: "The remaining bases can still function for the time being."
Regardless of whether you can find a solution in the end, you won't go wrong if you do things first. At worst, you'll waste more time and just set it up later.
"Captain, the latest observation data has been generated."
Xiao Xi's voice came out.
"Say it."
"The mass of the asteroid has been determined. Its mass is 430 million tons, with an error of 2 million tons. The surface temperature is 22K..."
22K is approximately equivalent to minus 251 degrees Celsius.
The mass of 430 million tons is much lower than the originally estimated mass of 600 million tons. However, this mass difference will not bring any difference in the consequences of the impact - it is like jumping from a 20-story building and jumping from a 15-story building.
The same thing happens next, and the ending is the same. But this number still arouses Zhao Changxing's doubts.
"How can the mass difference be so big? Also, how can its temperature be so high?"
For comparison, the average surface temperature of Sedna is only about 12K. This temperature also represents the general temperature of a star so far away from the sun.
"Sorry Captain, I didn't know."
Zhao Changxing thought for a while and said, "Do you have the latest photos? The ones with higher resolution."
At this moment, the asteroid is still about 5 million kilometers away from Sedna. At this distance, it is theoretically possible to take pictures with higher resolution. Although the sunlight here is weak and it is pitch black.
"Okay Captain."
A picture was projected directly in front of everyone by Xiao Xi's control of the projector.
Zhao Changxing had seen its picture before, but this time it was clearer.
"Is it hollow?" Zhao Changxing asked: "Otherwise, how could it be so light?"
The so-called lightness is relative to its volume. Its density is too low, and based on the surface material composition that has been observed so far, its density should be more than this low.
Since there is a contradiction, it can only be explained by thinking that it is hollow. However, if its internal density is so low, why does its volume not shrink?
Even such a small asteroid has its own gravity. If there are gaps inside it, from a macro perspective, it will definitely fill these gaps under its own gravity.
But now it is obvious that there is a contradiction.
This is strange.
Zhao Changxing wrote down this doubt.
"Everyone, go get ready."
After arranging some people to make preliminary preparations, Zhao Changxing and several people who performed relatively well during this period stayed and began to discuss whether they could find ways to avoid collisions on the basis of the existing situation.
After all, decades of hard work have been put into this Sedna planet. No one is willing to give up these things until it is absolutely necessary and at the last moment.
But after more than an hour of discussion, nothing came of it. People did not find any possibility to prevent the asteroid from impacting.
The rest seemed to have resigned themselves to their fate and completely given up hope. Only Zhao Changxing was still thinking.
The next day, the dismantling work of the No. 2 Comprehensive Base had already begun. Zhao Changxing led people to the base, which had completed its framework and only needed some core components to be put into operation. They stood and watched for a long time.
People seem to be instinctively resisting the subsequent demolition work from deep within their hearts.
"Cheer up!" Zhao Changxing shouted: "If the old one doesn't go, the new one won't come. We will build a bigger and better one in the future! By then, everyone will have their own independent house with a living room and kitchen.
The one with a bathroom!”
"Back on earth, people lived in houses like that. Some houses even had lawns and gardens. When spring came, the flowers were in full bloom, and they looked so colorful. It looked awesome."
Everyone showed a look of fascination.
"Work!"
Zhao Changxing strode forward, entered the base, and pulled out a sensor with a strong pull.
He encouraged himself and took the lead, and the atmosphere finally became a little more lively.
He didn't know how long he had been doing it, but a question suddenly appeared in his mind.
"Why is the temperature of this asteroid so high and the density so low?"
After thinking for a while, he really couldn't figure it out, so he gave up thinking about this issue.
But I don’t know why, in the subsequent work, this question always pops up from time to time, making him think about it involuntarily and subconsciously. Just like the instinct of a scientist or engineer.
Even though Zhao Changxing has been doing menial jobs over the years, and he seems to have nothing in common with scientific researchers who work with high-end research institutions all day long, he is actually a real scientist, and he has excelled in many categories.
Have a very high reserve of knowledge.
In fact, this is true for every astronaut who left the earth with Zhao Changxing to implement the Fire Project. If they were not so outstanding, they would not have been selected through the layers of selection.
"Why exactly?"
His thinking still failed to gain anything. It was still the same sentence, the universe is full of wonders, and if every question could be clarified, human civilization would have dominated the entire universe long ago.
He was seriously thinking about this problem in every free time, deducing various possibilities, but every possibility was ruled out by him. Until one day, a man tried to walk through the isolation gate with a bag of things.
, but because this was a vacuum environment, the air pressure caused the package to expand, and it could not pass through the isolation door. Then when he had to deflate before finally walking through, Zhao Changxing suddenly thought of a possibility.
"Is that so? If so..."
Zhao Changxing murmured, his heart suddenly filled with heat.
Reason told him that this possibility is extremely low, but, but, if this is true, then, then...
"I'm going to do some field exploration on that asteroid."
After finishing his work for the day, he told people his plan.
This made people immediately confused.
"What are you doing there?"
"The distance is still far, and the Spark spacecraft cannot move. Can the landing spacecraft alone support it?"
Zhao Changxing did not share his guess. He just said: "I'll go take a look for myself. Maybe I can find something we need there."
