The last human in the universe

Chapter 2 Landing
In the Tinder plan formulated by many outstanding scientists of human civilization, after arriving at Sedna, the first thing the astronauts need to do is not to cultivate human beings and develop the population through sperm and egg banks immediately, but to firstly accomplish Feed themselves.

There are complete soilless cultivation equipment on the Tinder spacecraft. According to the original plan, after arriving at Sedna, the astronauts will build a soilless cultivation workshop on this planet, and use various equipment carried on the spacecraft to Planting crop seeds began to produce food and stored it for subsequent population development tasks.

But a key point is that at this moment, he is the only one left among the twenty astronauts.With his own strength, even if he works overtime and everything goes well, it will take at least two months to set up the soilless cultivation workshop on Sedna.The growth of crops also takes at least one month, plus the remaining ten days of the voyage at this moment, and some necessary preparation time after arriving at the orbit of Sedna star-in ten days, then , counting from this moment to Zhao Changxing's first food supplement, it will take a total of about 110 days.

For such a long time, what did I rely on to support the past?
Zhao Changxing gathered up the food scattered around the third floor, such as some snacks, and put on his space suit to walk around the wreckage of the third floor, and found some rice, wheat and frozen food. Meat and other things, after a general calculation, these things are probably enough for me to barely support myself for a month.

There is an 80-day food gap left.

How to do?Are you going to eat seeds?
No, no.At this moment, each type of seed on the Tinder spacecraft may be the only one in the universe, and if you eat it, there will be no more.The future human world - if it can successfully revive human civilization - will lose this crop forever.

Zhao Changxing frowned deeply.

"Don't worry about that much, let's talk about it first."

For Zhao Changxing, or human civilization, the success of entering orbit is directly related to the survival of human civilization.Because of the damage to the main shaft of the spaceship, 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 for the revival of human civilization would be impossible to talk about.

This was originally a common task 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 available to observe Sedna Star as detailed as possible, and made a lot of calculations.Finally, ten days later, after a series of attitude adjustments, orbit and speed adjustments, the Tinder spacecraft finally successfully entered orbit.

From now on, if there is no external force, the Tinder spacecraft will always be at a height of about 50 kilometers from the surface of Sedna, orbiting it at a relative speed of 380 meters per second.

At this speed, the Tinder spacecraft can circle it every two and a half hours.

Looking at the huge planet under his feet, Zhao Changxing thought silently: "Here will be the second home of human civilization."

At this moment, a strange scene appeared in front of Zhao Changxing.

Even if the planet is 130 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, and its visual magnitude is as high as -18, which can be seen on the earth About 100 times as bright as the brightest moon.

Normally, the sun seen at this distance should be only 50 times as bright as the moon when it is at its brightest, but the process of the black hole swallowing the sun makes it look even brighter.

However, the disc-shaped structure of the sun cannot be seen here, and the black hole cannot be separated from the sun. The two have merged into one, and it seems to be just a small bright spot.

Such a bright brightness can already distinguish the obvious day and night changes on Sedna.At this moment, the Tinder spacecraft moved to the daytime side of Sedna, so Zhao Changxing saw the endless dark red land, the bumps and depressions on it, the large plains, and the continuous mountains.

Compared with the earth with a diameter of more than 12000 kilometers, Sedna, which is only more than 1000 kilometers in diameter, is undoubtedly a small person.But the highest peak on it is almost more than 1 meters, higher than Mount Everest.

This is a wonderful, alien style that is very different from the earth.

Zhao Changxing didn't waste too much time admiring the scenery.After resting for a while, he ate a bit stingily, and then directed Xiao Xi to launch some specially-made satellites by remote control.

There are ten satellites in total, and they carry fuel, which can propel themselves to a suitable orbit.

They are all exploration satellites, used to detect the geology, minerals, environment, magnetic field, etc. of Sedna Star.Zhao Changxing can take the next step only when he has a comprehensive grasp of the information about this dwarf planet.

As for communication satellites, they are not needed yet.The Tinder spacecraft in orbit is more than adequate for this task.

After finishing some routine tasks and waiting for the satellite to send back data, Zhao Changxing finally had the time and energy to think about this most important issue.

Where should I find food to carry the 80-day gap.

He envisioned first doing small-scale rapid planting in the Tinder spacecraft to obtain food, such as growing some fast-growing vegetables, but after field measurements, he had to give up this plan.

There wasn't much soil in the Tinder ship for him to start planting.The soilless cultivation workshop is a complete set of equipment, which cannot be built and assembled in the Tinder spacecraft.Even if it is possible, the time-consuming is not much less than the time it takes to build and assemble on the surface of Sedna.

He envisioned streamlining the equipment as much as possible and using the least amount of time to complete the construction on the surface of Sedna, but he also had to give up after the calculation.

Doing this can only save about 10 days at most, and will leave serious hidden dangers, which will cause great trouble for follow-up operations, and the gains outweigh the losses.

The path of growing your own food seems completely out of the question.The only thing that can be tried is probably to obtain food from the outside world.But here is a distant deep space more than 100 billion kilometers away from the sun, and obtaining food from the outside world is tantamount to fantasy.

He has devoted all his time to researching this problem except for daily maintenance work, but so far, he has not made any progress.

Ten days passed in a flash, 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 move the goods with Xiaoxi's help, preparing to transport them to the surface of Sedna.

At this moment, there are still ten days left in the food reserve.

The problem is serious, but it doesn't mean he can suspend the rest of his work.If the construction of the soilless cultivation workshop is not started now, there will be no food supplement after 90 days.

When the engineers designed the soilless cultivation workshop, they adopted a modular design, and it was not difficult to assemble it. This is also considering 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 the moment, it still seems a bit difficult.

But no matter how difficult things are, they still have to be done.

The cargo compartment of the small landing spacecraft "Falcon" has been occupied by boxes one by one.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, the Falcon spacecraft has no faults."

"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 circle and the third circle of the Pyro spacecraft, slowly disengaged, and the attitude adjustment engine ignited smoothly, pushing it to slowly distance from the Pyro spacecraft.Afterwards, the main engine was ignited, and the speed of the Falcon spacecraft began to decrease, and it slowly descended towards the scheduled landing point on the Sedna [-] plain.

This landing point was deliberately selected by Zhao Changxing after comparing many places and data.The terrain here is flat, and there are a lot of mineral deposits around it, as well as the most precious water ice.If there is no accident, all the construction of the human world in the future will be carried out here.

The difficulty of landing on Sedna is much easier than that on Earth.After all, there is almost no atmosphere here.For an excellent astronaut like Zhao Changxing, it is simply within reach.

With the start of the recoil engine of the Falcon spacecraft, a layer of faint mist suddenly appeared on the dark red surface of Star Sedna under the sun's rays. The dark red Thorin was frozen into a solid gas. , dry ice, water ice, etc. melted rapidly, directly rising into space.

Sedna's gravity isn't strong enough to hold them.

The spaceship finally landed smoothly, the hatch opened, and Zhao Changxing, who was wearing a space suit, actually stepped on its land.

Feeling the gravity that is less than one-twentieth of the earth, looking at the endless dark red land, looking at the bright but not dazzling sun in the sky, Zhao Changxing's heart is full of wonderful feelings.

At the moment where the Falcon spacecraft is, all the Thorin and dry ice have been lifted up, exposing the dark gray stone ground under their feet.He took out the heater again, cleaned up the surrounding area, and finally cleared out a piece of ground covering an area of ​​about 100 square meters.

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

All the construction in the first phase is temporary, and the purpose is to support the astronauts to obtain self-sufficiency from the planet as quickly as possible.The second phase of construction is permanent, and when the second phase of construction progresses to a certain extent, these 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 this Sedna star with extremely low gravity, their weight is only a few kilograms. Was easily taken down.

Construction work then began.
