Black technology: starting with space jump machine

[No data in the database, this asteroid is of the undiscovered type. According to the trajectory and spectral test results, it is suspected to have been split from other asteroids not long ago. ]

[Captain's order: The asteroid with a volume of 2134 cubic meters will be captured, and the Kunlun will be tested for the 169th time to urgently obtain raw materials from space. ]

Five spherical robots flew out of the Kunlun's exclusive ejection port. After arriving at the asteroid, more than 30 disc-shaped robots that had been seen in the space city were ejected from the five spherical robots.

After successfully adsorbing them to the elliptical asteroid, a positively charged electromagnetic shield was generated, and an electromagnetic reaction began to occur between the negatively charged circular robots, coating the surface of the asteroid with a layer of magnetism.

After completing all this, the spherical robot pushed the asteroid to the bottom of the Kunlun, and the magnetic field slowly sucked it into the cabin. This series of operations took only 10 minutes.

After that, this asteroid full of precious rare earths will be transported back to the first phase base of Ceres by Kunlun, and quickly decomposed into various materials to promote engineering construction.

Xiao Liu sat in the command seat and stretched his body for a long time. This is the second month since they came to the asteroid belt.

Starting from the space city, Kunlun even took only sixteen days to reach the asteroid belt from the Earth-Moon orbit. Under the leadership of Professor Mao, they quickly started the preliminary construction of the forward base on Ceres.

Now there are only one-fifth of the crew on Kunlun. The others are already busy with the construction of the forward base. Xiao Liu, the third officer, is on duty to command Kunlun to collect materials outside the asteroid belt.

"I heard that our bath water will be filtered and turned into drinking water in the ecological laboratory?"

On the return voyage, the excellent shipborne main engine can perfectly replace manual control. Xiao Liu simply took advantage of the free time to relax himself.

As soon as we arrived at the public bathhouse, a familiar companion, who looked like he had just finished a bath, put on his one-piece space suit while still wet, and did not forget to put the one-piece hat on his equally wet head.

The space suit fluttered slightly, and after two or three seconds, his whole body became dry.

"I suggest you learn about the circulation system of the spacecraft."

"Hey? Isn't it? Everyone says so! They even put some excrement"

"Don't let the professors hear it, or you will be pulled to make up lessons"

The two stood in front of the door of the public bathhouse and chatted for a while. The companion who had just finished a bath placed two golden metal cylinders on both sides of the door. After he skillfully put his hands on them, the moisture absorbed by the clothes quickly flowed from the space suit into the metal cylinders, and then he said goodbye and left, leaving the bathhouse for Xiao Liu to use alone.

How to deal with personal hygiene in zero gravity is also a big problem. If not handled properly, the large suspended water droplets may even cause suffocation. Originally, experts suggested that the space suits be equipped with nanorobots, which are directly responsible for the cleaning function and can also save a large space inside the spacecraft.

But it has been proven that humans need to take a bath not only for cleaning, but also for regulating the body and mind.

Enjoying a hot bath in space can relax the mind.

At least Xiao Liu, who felt much more comfortable, thought so. He came out of the bathhouse, moved quickly holding the sliding rod integrated with the wall, and returned to the command room, but he turned to other cabins.

This is a room of about 15 square meters. Considering that some people cannot adapt to the long-term use of the rest cabin, several dormitories are specially reserved.

The single bed, wardrobe and table and stool are integrated with the spacecraft. Considering that the narrow environment is not conducive to the execution of the mission, a large glass is built directly opposite the single bed, which is connected to the space scenery outside the Kunlun in real time.

In fact, it was Xiao Liu's first time to come to a single dormitory. The rest cabin also comes with a virtual reality function, which is much more popular than the experts expected.

Xiao Liu, who was in a good mood, lay on the bed he had not seen for a long time, and he actually felt a subtle discomfort.

After tossing and turning for a while, he simply lay on the bed and suddenly said: "Connect Kunlun."

The text appeared at the door of the projection glass: [What can I do for you? ]

"Connect the external viewfinder, the direction is the asteroid belt."

[Completed, it will be displayed on the projection glass in your dormitory in five seconds. ]

Thousands of rocks of different sizes appeared on the projection glass in the dim room.

In the viewfinder, you can see them spreading from the deep space of the universe, passing an arc in front of Kunlun and disappearing into the depths of space. They are the remnants left over from the distant formation of the solar system - the asteroid belt between the orbits of Jupiter and Mars.

The current location of Kunlun is the asteroid belt mining area built with the dwarf planet Ceres as the core area and radiating nearly 100,000 kilometers to the left and right.

This will become the main source of materials for the forward base. After the forward base is built, it will also become a springboard for the blue planet to advance into deep space.

Judging from the current forward construction speed, the speed of human development of asteroids is much higher than that of Mars. This is because the industrial work efficiency in zero gravity or microgravity is much higher than that in gravity environment!

According to the results of computer simulation, when the forward base on the asteroid belt can rely on the materials mined from the surrounding environment to advance into deeper space, Mars still needs the transportation of materials.

This is why the Forward Base was chosen on Ceres instead of Mars!

But Mars is a planet after all, and it has an asteroid belt with incomparable conditions! Because it is the only planet in the solar system that can be transformed into a habitable planet for humans!

Mars once had a large area of ​​warm ocean and atmosphere, but as the core gradually cooled, volcanic activity disappeared and the magnetic field at the poles began to weaken. The temperature drop caused the carbon dioxide attached to the seawater to no longer return to the atmosphere, and the greenhouse effect lost energy and material support. In a vicious cycle, the atmosphere gradually weakened under the action of the solar wind, and a large amount of water vapor and gas escaped into space. The ocean of Mars slowly disappeared over the years and finally became the orange-red color it is today. (Note 1)

In the planning of Base Zero, when the Forward Base can start to output materials, it will also try to establish a Mars research base on Phobos.

The base will be responsible for implementing the planetary transformation plan and turning Mars into the second home of mankind!

The Mars transformation plan will build large magnetic field generators at the poles so that the solar wind will no longer take away the material of the Martian atmosphere at will! The simultaneous projects also include heating the frozen soil at the poles of Mars to release water vapor and carbon dioxide, and transporting water ice asteroids from the asteroid belt to Mars to increase the thickness of the atmosphere and gradually warm Mars.

But such a large project is not a career that can be completed overnight, not to mention that humans are also facing the threat of an unknown fleet. The Mars transformation plan can only be put aside in the face of the crisis of civilization survival.

Xiao Liu certainly understands the difference in priorities here, but secretly sighs that if human technology is more powerful, it would be perfect if they could have them all!

"Oh? Is this a US exploration satellite?"

At this time, the projection glass suddenly showed that the spacecraft radar had discovered something from the blue planet. Lu Yu laughed as soon as he saw it, and said to himself: "Then we have to get over and escort the 'guests', otherwise the small fragments will completely destroy them!"

Kunlun slowly approached the exploration satellite, and the size difference between the two immediately stood out, just like the difference between whales and shrimps. On one side is a spacecraft that is thousands of meters long, and on the other side is only a dozen meters even with the solar sails on both sides.

In the stage of planetary civilization, big is beautiful, big is strong!

It is hard to imagine that they were born on the same planet and created by the same intelligent race.

The gap in technology is so obvious when it is reflected in the creation!

Note 1: The theory of the cooling of the core of Mars quoted here is one of the hypotheses that is currently more accepted by the scientific community.
