In the fire plan formulated by many outstanding scientists in human civilization, after arriving at Sedna, the first thing that astronauts need to do is not to immediately cultivate humans and develop populations through sperm and egg banks, but to feed themselves first.

There are complete soilless cultivation equipment on the Tinder spacecraft. In the original plan, after arriving at Sedna, astronauts will build a soilless cultivation workshop on this planet, and start producing grain through various crop seeds carried on the spacecraft and stockpile them to cope with subsequent population development tasks.

But one key point is that he is the only one left of the twenty astronauts at this moment. With his own strength, even if you work overtime, everything goes well. It will take at least two months to match the soilless cultivation workshop on the Sedna Star. The growth of crops will take at least one month. In addition, the remaining ten days of voyage at this moment, and some necessary preparation time after reaching the orbit of the Sedna Star - based on ten days, then, from now on, it will take about 110 days in total to Zhao Changxing’s first food supplement.

How can I support myself in this long period of time?

Zhao Changxing gathered the food scattered everywhere outside the third circle, such as some snacks, put on a space suit and wandered around the wreckage of the third circle, and found some rice, wheat, frozen meat, etc. After all, he calculated that these things were probably enough for him to barely support for a month.

There is still 80 days left in the food gap.

What to do? Do you want to eat seeds?

No, no. At this moment, every type of seed on the Tinder spacecraft may be the only one in the universe, and it will never be eaten. The future human world - if it can successfully revive human civilization - will lose this crop forever.

Zhao Changxing's brows frowned deeply.

"No matter how much you have, let's talk about it first."

For Zhao Changxing, or human civilization, whether it can enter orbit successfully is directly related to the life and death of human civilization. Because of the damage to the main shaft of the spacecraft, there is only one chance. If it fails, it will never be able to enter the orbit of the Sedna Star. Without the material supplement on this dwarf planet, the plan for the revival of human civilization is simply impossible to talk about.

This was originally a joint mission of twenty astronauts, but at this moment, all the responsibilities fell on Zhao Changxing's shoulders.

He cheered up and began to use any means he could use to observe the Sedna Star as detailed as possible and perform a lot of calculations. Finally, ten days later, after a series of posture adjustments, orbit and speed adjustments, the Torch spacecraft finally successfully entered orbit.

From now on, without external force, the Tinder spacecraft will always be around it at a height of about 50 kilometers from the surface of the Sedna Star, at a relative speed of 380 meters per second.

Running at this speed, the Tinder spacecraft can circumvent it every two and a half hours.

Looking at the huge planet under his feet, Zhao Changxing thought silently in his heart: "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 this planet is 13 billion kilometers away from the sun, it takes about 12 hours to reach the sun's light, and the sun is still extremely bright, with its visual magnitude as high as -18, about 100 times the brightest moon that can be seen on Earth.

It was not so bright originally. Normally, the sun seen at this distance should be only 50 times brighter than the moon when it was brightest, but the process of the black hole swallowing the sun makes it look brighter.

However, the disc-shaped structure of the sun cannot be seen here, nor can the black hole be separated from the sun. The two have become one, and it seems to be just a small highlight.

Such brightness can already distinguish the day and night changes on the Star Sedna. At this moment, the Tinder spacecraft was running to this side of the Star Sedna during the day, so Zhao Changxing saw the endless dark red earth, the bulges and sags on it, the large plains, and the continuous mountains.

Compared to Earth with a diameter of more than 12,000 kilometers, Sedna Star, which has a diameter of only more than 1,000 kilometers, is undoubtedly a small man. But the highest peak above 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 much time on enjoying the scenery. He took a moment of rest and ate a little bit of food with a stingy bite. He directed Xiaoxi and remotely controlled some special satellites to launch them out.

There are ten of these satellites in total, and they carry fuel and can push themselves to move to a suitable orbit.

They are all detection satellites used to detect the geology, minerals, environment, magnetic fields, etc. of Sedna. Only by fully understanding the information about this dwarf planet can Zhao Changxing take the next step.

As for communication satellites, they are not needed for the time being. The Tinder spacecraft that stays in orbit is enough to undertake 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 get through the 80-day gap?

He had imagined that he would first perform small-scale rapid planting in the Tinder spacecraft to obtain food, such as growing some vegetables that can grow quickly, but after field measurements, he had to give up this plan.

There is not much soil in the Tinder spacecraft that can be started. The soilless cultivation workshop is a complete set of equipment that cannot be built and assembled in the Tinder spacecraft. Even if it can, it will take less time than the time it takes to build and assemble on the Sedna Star surface.

He had imagined the simplification of equipment as much as possible and completed the construction on the Sedna Star surface with the least time, but he had to give up after calculation.

Doing this can only save about 10 days at most, and it will leave serious hidden dangers, causing great trouble for subsequent operations and not worth the cost.

The way to produce food by yourself seems to be completely unworkable. The only thing you can 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, and getting food from the outside world is nothing more than a fantasy.

He devoted all his time besides his daily maintenance work to the study of this issue, but so far, he has not made any progress.

Ten days passed by, and the data collected by the exploration satellite was enough to support him in the next task. He had to temporarily put down his concerns about the future and began to transport the goods with Xiaoxi's help, preparing to transport them to the surface of Sedna Star.

There are still ten days left in the food reserve.

This problem is serious, but it does not mean that he can suspend the rest of his work. If he does not start the construction of the soilless cultivation workshop now, there will be no food supplements in 90 days.

When the engineers designed the soilless cultivation workshop, they adopted a modular design. It was not difficult to assemble it. This was also considered that the astronauts had weak engineering capabilities after arriving at the destination. However, this was not difficult for at least five astronauts teams, and for Zhao Changxing alone, it still seemed a bit difficult.

But no matter how difficult it is, it still has to be done.

The cargo warehouse of the small landing spacecraft "Falcon" has been occupied by boxes. Zhao Changxing sat in the driver's seat, took a deep breath, and pressed the start button.

"The self-test passes. Captain, we are lucky, the Falcon spacecraft has no faults."

"It's good if there's no fault, I'm leaving. Turn on the fixture."

The Falcon spacecraft, fixed on the middle main axis of the second and third circles of the Tinder spacecraft, slowly separated, and adjusted its attitude and the engine ignited smoothly, pushing it to slowly distance it from the Tinder spacecraft. After that, the main engine ignited, the Falcon spacecraft's speed began to decrease and slowly landed towards the predetermined landing point on the Sedna Star 1 plain.

This landing point was specially selected by Zhao Changxing compared many places and data. The terrain here is flat, there are a large number of minerals around it, and the most precious water ice. If there is no accident, all construction of the human world will be carried out here in the future.

Landing on Sedna is much easier and easier than the Earth. After all, there is almost no atmosphere here. It is very easy for an excellent astronaut like Zhao Changxing.

As the Falcon spacecraft recoil engine turned on, a faint mist suddenly appeared on the surface of the Sedna Star, which was dark red under the sun. The dark red Torino was frozen into solid gas, dry ice, water ice, etc. quickly melted and rose directly into space.

The gravity of the Sedna stars is not 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 less than one-twentieth of the earth, looking at the endless dark red earth, and looking at the bright but not dazzling sun in the sky, Zhao Changxing felt a wonderful feeling.

At this moment, all the Torino and dry ice and other things were raised, revealing the dark gray stone floor under his feet. He took out the heater and cleaned the surrounding area for a while, and finally cleared a piece of ground covering an area of ​​about 100 square meters.

For the first phase of construction, this area is enough.

All construction in the first phase is temporary, and the purpose is to support astronauts to obtain self-sufficiency 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 first phase of construction will be demolished and their building materials will be used in the second phase of construction.

Carry out encapsulated boxes from the Falcon spacecraft - each of them weighs 120 kilograms, but on this very small gravity, they weigh only a few kilograms and can be easily taken off.

Construction work begins.
Chapter completed!
