In the Fire Plan formulated by many outstanding scientists of human civilization, the first thing the astronauts need to do after arriving on Sedna is not to immediately cultivate humans and develop the population through sperm and egg banks, but to first Feed themselves.
The Spark spacecraft has complete soilless cultivation equipment. According to the original plan, after arriving at Sedna, the astronauts will build a soilless cultivation workshop on the planet and use various equipment carried on the spacecraft to Plant seeds to start producing food and store it to cope with subsequent population development tasks.
But a key point is that he is the only one left among the twenty astronauts at this moment. With his own strength, even if everything goes well if he works overtime, it will take at least two months to put together a soilless cultivation workshop on Sedna. It also takes at least a month for the crops to grow, plus the remaining ten days or so of the voyage, as well as some necessary preparation time after arriving in the orbit of Sedna - just based on ten days, then , counting from this moment until Zhao Changxing gets food supplement for the first time, it will take a total of about 110 days.
How can I support myself for such a long time?
Zhao Changxing gathered up the food scattered outside the third circle, such as some snacks, put on his space suit and walked around the wreckage of the third circle, and found some rice, wheat and frozen food. Meat and other things, after total calculation, these things are probably enough for me to barely support myself for a month.
There is still 80 days of food shortage left.
what to do? Do you want to eat the seeds?
No, it can't be done. At this moment, every type of seed on the Spark spacecraft may be the only one in the universe. If you eat it, there will be no more seeds. The human world in the future - if it can successfully revive human civilization - will lose this crop forever.
Zhao Changxing's brows frowned deeply.
"Don't worry about it for now, let's get into orbit first and then talk about it."
For Zhao Changxing, or human civilization, whether it can successfully enter orbit is directly related to the life and death of human civilization. Because the main shaft of the spacecraft is damaged, there is only one chance. If it fails, it will no longer be able to enter the orbit around Sedna. Without the material supplement on this dwarf planet, the plan to revitalize human civilization would be impossible to talk about.
This was originally a joint mission of twenty astronauts, but now all the responsibility fell on Zhao Changxing's shoulders.
He cheered up and began to use any means at his disposal to observe the Sedna star in as much detail as possible and conduct a large number of calculations. Finally, ten days later, after a series of attitude adjustments, orbit and speed adjustments, the Pyrotechnic spacecraft finally successfully entered orbit.
From now on, if there is no external influence, the Spark spacecraft will always orbit Sedna at an altitude of about 50 kilometers from the surface of the planet, orbiting it at a relative speed of 380 meters per second.
At this speed, the Spark spacecraft can orbit it every two and a half hours.
Looking at the huge planet at his feet, Zhao Changxing thought silently: "This will be the second home of human civilization."
At this moment, what appeared in front of Zhao Changxing was a strange scene.
Even if the planet is 13 billion kilometers away from the sun, it takes about 12 hours for the light from the sun to reach here. The sun is still extremely bright, with a visual magnitude as high as -18, which can be seen from the earth. The brightness of the brightest moon is approximately 100 times.
It would not have been so bright originally. Normally, the brightness of the sun seen from this distance should be only 50 times that of the moon when it is at its brightest. However, the process of the black hole swallowing the sun made it look even brighter.
However, the disk-shaped structure of the sun cannot be seen here, nor can the black hole be separated from the sun. The two have merged into one, and they look like just a small bright spot.
Such a bright brightness can already distinguish obvious day and night changes on Sedna. At this moment, the Spark spacecraft arrived at the daytime side of Sedna, so Zhao Changxing saw the endless dark red land, the ridges and depressions on it, the large plains, and the continuous mountains. mountains.
Compared with the Earth, which has a diameter of more than 12,000 kilometers, Sedna, with a diameter of only more than a thousand kilometers, is undoubtedly small. But the highest peak on it is almost more than 10,000 meters, higher than Mount Everest.
This is a wonderful, alien style that is completely different from the earth.
Zhao Changxing didn't waste too much time admiring the scenery. After taking a short rest and eating something rather stingily, he directed Xiao Xi to launch some special satellites remotely.
There are ten of these satellites in total. They carry their own fuel and can propel themselves to a suitable orbit.
They are all exploration satellites used to detect the geology, minerals, environment, magnetic field, etc. of Sedna. Only by fully grasping the information about this dwarf planet can Zhao Changxing take the next step.
As for communication satellites, they are not needed yet. The Spark spacecraft, which remains in orbit, is adequate for this task.
After finishing some routine things and waiting for the detection satellite to return data, Zhao Changxing finally had the time and energy to think about this most important issue.
Where should I find food to bridge the 80-day gap?
He thought about first conducting small-scale rapid planting in the Spark spacecraft to obtain food, such as planting some fast-growing vegetables, but after field measurements, he had to give up this plan.
There wasn't much soil in the Spark ship for him to start planting. The soilless cultivation workshop is a complete set of equipment that cannot be built and assembled in the Spark spacecraft. Even if it could be done, the time it would take would not be much less than the time it would take to build and assemble it on the surface of Sedna.
He thought about streamlining the equipment as much as possible and completing the construction on the surface of Sedna in the least amount of time, but he had to give up after calculations.
This can only save about 10 days at most, and will leave serious hidden dangers, causing great trouble for subsequent operations, and the gain outweighs the loss.
Producing your own food seems like a completely impossible path. The only thing left to try is probably to get food from the outside world. But this is a distant deep space more than 10 billion kilometers away from the sun. Obtaining food from the outside world is nothing short of a fantasy.
He devoted all his time besides his daily maintenance work to researching this problem, but so far, he has made no progress.
Ten days passed by, and the data collected by the exploration satellite was enough to support his next mission. He had no choice but to temporarily put aside his worries about the future and began to transport the goods with the help of Xiao Xi, preparing to transport them to the surface of Sedna.
At this moment, there are ten days left in the food reserve.
Although this problem is serious, it does not mean that he can suspend the rest of his work. If we don’t start building a soilless cultivation workshop now, there will be no food replenishment after 90 days.
When the original engineers designed the soilless cultivation workshop, they adopted a modular design, and it was not difficult to assemble it. This also took into account the weak engineering capabilities of the astronauts after arriving at the destination. However, this is not difficult for a team of at least five astronauts. For Zhao Changxing alone at this moment, it still seems a bit difficult.
But no matter how difficult the thing is, you still have to do it.
The cargo hold of the small landing spacecraft "Falcon" has been occupied by boxes one after another. Zhao Changxing sat in the driver's seat, took a deep breath, and pressed the start button.
"The self-inspection passed. Captain, we are very lucky. There is no fault in the Falcon spacecraft."
"As long as there's no malfunction, I'm off. Open the fixtures."
The Falcon spacecraft, which was fixed on the main axis between the second and third circles of the Spark spacecraft, slowly detached, and its attitude adjustment engine ignited smoothly, pushing it away from the Spark spacecraft. After that, the main engine was ignited, and the speed of the Falcon spacecraft began to decrease, and it slowly landed towards the planned landing point on the Sedna Planet 1 plain.
This landing point was specially selected by Zhao Changxing after comparing many places and data. The terrain here is flat, and there are a large number of mineral deposits around it, as well as the most precious water ice. If there are no accidents, all future construction of the human world will be carried out here.
Landing on Sedna is much easier than on Earth. After all, there is almost no atmosphere here. For an outstanding astronaut like Zhao Changxing, it is easy to get it.
As the Falcon spacecraft's recoil engine was turned on, a layer of light mist suddenly appeared on the surface of Sedna, which was dark red under the sun. The dark red Thorin was frozen into solid gas. , dry ice, water ice, etc. quickly melted and rose directly into space.
Sedna's gravity is not strong enough to retain them.
The spacecraft finally landed smoothly, the hatch opened, and Zhao Changxing, wearing a spacesuit, truly stepped on its ground.
Feeling the gravity of less than one-twentieth of the earth, looking at the endless dark red land, and looking at the bright but not dazzling sun in the sky, Zhao Changxing was filled with a wonderful feeling.
At this moment, where the Falcon spacecraft is, all Tolin and dry ice have been lifted up, revealing the dark gray stone ground beneath their feet. He took out the heater again and cleaned up the surrounding area. Finally, he cleared an area of approximately 100 square meters.
This area is sufficient for the first phase of construction.
All construction in the first phase is temporary, and the purpose is to support astronauts to obtain self-sufficiency capabilities from this planet as quickly as possible. The second phase of construction is permanent, and when the second phase of construction reaches a certain level, the buildings in the first phase will be demolished, and their building materials will be used in the second phase of construction.
Move the packaged large boxes out of the Falcon spacecraft - each of them weighs 120 kilograms, but on the Sedna planet with extremely small gravity, they only weigh a few kilograms. It was taken down easily.
Construction work then began.
