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.
There is complete soilless cultivation equipment on the Spark spacecraft. 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.
Planting crop seeds begins to produce food and reserves 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 he works overtime and everything goes well, the soilless cultivation workshop on the Sedna planet will be at least
It will take two months. It will also take at least a month for 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
Calculated based on ten days, then, from now on, it will take a total of about 110 days until Zhao Changxing receives food supplements for the first time.
What did you rely on to support yourself 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 a total calculation, these things are probably enough to survive for a month.
There is still 80 days of food shortage left.
What should I do? Should I eat the seeds?
No, no. 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. The future human world - if you can successfully revive human civilization
If so - the crop will be lost 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 for human civilization, whether it can successfully enter orbit is directly related to the life and death of human civilization. Because the main axis 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 falls on Zhao Changxing's shoulders.
He cheered up and began to use any available means to observe the Sedna star in as much detail as possible, and made a lot of calculations. Finally, ten days later, after a series of attitude adjustments, orbit and speed adjustments
, the Spark spacecraft finally successfully entered orbit.
From this moment on, if there is no external force, the Spark spacecraft will always orbit Sedna at an altitude of about 50 kilometers from the surface, orbiting it at a relative speed of 380 meters per second.
Operating 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 an apparent magnitude of -18, which is the most visible from the earth.
About 100 times as bright as the brightest moon.
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 moved to the day side of Sedna, so Zhao Changxing saw the endless dark red earth.
I saw the bulges and depressions on it, the vast plains, and the continuous 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, which is higher than Mount Everest.
This is a wonderful, alien style that is completely different from the earth.
Zhao Changxing did not 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 by remote control.
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 staying in orbit is enough to undertake this task.
After finishing some routine tasks 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 is not much soil in the Spark spacecraft 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 built, it would be more time-consuming than building and assembling it on the surface of Sedna.
Not much less time.
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 food by oneself seems to be a completely impossible path. The only way to try is to obtain food from the outside world. But this is a distant deep space more than 10 billion kilometers away from the sun, and obtaining food from the outside world is no different.
Night story.
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 to temporarily put aside his worries about the future, and began to move the goods with the help of Xiao Xi, preparing to transport them to Sedna
Go to the surface of the stars.
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 he does not start building a soilless cultivation workshop now, there will be no food replenishment in 90 days.
When the original engineers designed the soilless cultivation workshop, they adopted a modular design. 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
The difficulty is 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" was already 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 is no fault, 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 the attitude adjustment engine ignited smoothly, pushing it to slowly distance itself from the Spark spacecraft. After that,
After the main engine was ignited, 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, there are a large number of mineral deposits around it, and there is also the most precious water ice. If there are no accidents, all construction of the human world will be carried out here in the future.
Landing on Sedna is much more difficult and easier than on Earth. After all, there is almost no atmosphere here. For an outstanding astronaut like Zhao Changxing, it is easy to do it.
As the Falcon spacecraft's recoil engine was turned on, a layer of light mist suddenly appeared on the surface of Sedna, which appeared dark red under the sun. The dark red Thorin was frozen into solid gas.
, dry ice, water ice, etc. melted rapidly 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 space suit, 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 was, all Tolin, dry ice and other things had been lifted up, revealing the dark gray stone ground under his feet. He took out the heater again and cleaned up the surrounding area, finally clearing out a large area.
Covering approximately 100 square meters of ground.
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 construction in the second phase is permanent, and, after
When the second phase construction progresses to a certain extent, the buildings in the first phase will be demolished and their building materials will be used in the second phase 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.
