After working as a cosmic scavenger for more than half a month, Xiao Yu realized a truth: Comets are all strong-willed people.
If calculated in terms of volume alone, comets close to stars can be regarded as the largest stars in the universe. The comet tail stretches out, with a maximum length of more than 100 million kilometers, like a huge broom, sweeping majestically
The universe. But only when you get closer can you realize how weak the comet is.
After traveling through the comet tail for more than half a month, Xiao Yu collected less than five kilograms of water. It can be imagined how thin the material in the comet tail is. This collection efficiency makes Xiao Yu extremely depressed. If Xiao Yu still has
As for hair, Xiao Yu would definitely pull it off in handfuls in frustration.
Xiao Yu is currently 30,000 kilometers above or below the ecliptic plane. Anyway, there is no up or down in the interstellar space. It can be said to be up or down.
The so-called ecliptic plane is an imaginary plane. It can be simply understood that most of the orbits of all planets in the star system are on the same plane, and this plane is the ecliptic plane.
This place is already quite close to the original Earth's orbit. Through the optical telescope, Xiao Yu can already see countless small black meteorites above, emitting a heart-stopping light.
Xiao Yu has already made orbital adjustments. He plans to follow the Earth's meteorites to orbit the sun for a while first. After all, collecting materials is the serious thing, although this speed is really a bit slow.
The lens of the optical telescope slowly swept across, and an inconspicuous figure entered Xiao Yu's field of vision.
This is an irregularly shaped meteorite, about thirty meters long, seven to eight meters wide, and five to six meters high. The light diffusely reflected from nearby stars illuminates it, and then the light is collected by Xiao Yu.
Xiao Yu's heart moved and he immediately made some simple analysis on the meteorite. The results of the analysis immediately cheered up Xiao Yu.
Analysis shows that this meteorite is composed of approximately 30% water, 69% iron, and trace amounts of nitrogen, silicon, hydrogen, oxygen, potassium and other elements. Among these trace elements,
Mostly hydrogen and oxygen.
"Is this...is this a gift from God to me?" Xiao Yu immediately became excited.
This meteorite has a volume of about one thousand cubic meters and a mass of more than three thousand tons! Even if hydrogen and oxygen each account for 0.1% of its mass, the total is as much as six tons! With so much fuel, it can
Did a lot of things.
In particular, there are more than 900 tons of water on it! After getting close to the sun, this water can be ionized into hydrogen and oxygen with the help of the ionization effect of the sun. This is another huge income. There are also more than 2,000 tons.
The amount of iron is enough for Xiao Yu to roughly repair the spacecraft.
"Capture it! We must capture it!" Xiao Yu made up his mind instantly.
At this time, the star blocking the meteorite moved away, and the sun's rays shone directly on it.
Under the heat of the sun, the solid water, solid hydrogen and oxygen on the surface of the meteorite immediately began to evaporate rapidly. Fountains began to appear on the fluffy surface. Countless gaseous materials were sprayed out, and the entire core was shrouded in a layer of white.
In the fog, a long tail dragged backwards.
Xiao Yu felt anxious when he saw it: "These are my treasures, they can't be wasted like this."
Xiao Yu immediately controlled the spacecraft to stand between the meteorite and the sun, and used his own solar panels to withstand the heat of the sun. Without the sunlight, the temperature of only a few K in the interstellar space immediately cooled it down.
The long white tail dissipated at a speed visible to the naked eye.
Xiao Yu breathed a sigh of relief and began to figure out how to truly put this gift bestowed upon him by God into his own pocket.
When a big, sweet cake is placed in front of you, you have enough motivation to make cutlery and other tableware. Xiao Yu no longer cares about energy consumption, controls the robot, searches the material storage room, and even some less important items
The equipment has been dismantled and planned to be recycled.
The equipment manufacturing room is the most closely protected place for Xiao Yu besides the main control room. Here, Xiao Yu has collected all kinds of the most basic and important machinery to ensure that he has sufficient manufacturing power after obtaining the raw materials. Fortunately, the equipment manufacturing room
During the previous great collision between heaven and earth, it did not suffer much damage.
As the robot worked day and night, a mechanical claw with about 300 meters of high-strength cable attached to the back was quickly created.
Xiao Yu is now only a few kilometers away from the meteorite. This distance, on an astronomical scale, is already close, but compared to Xiao Yu's catching power, it is still a bit longer. Xiao Yu
Yu had no choice but to carefully control the small spacecraft, adjust the power of the engine to the lowest level, and slowly approach the meteorite piece by piece, a few meters away.
It is actually very risky to do this. A distance of several thousand meters is the shortest distance for Xiao Yu to control the spacecraft to dodge. If this bottom line is crossed, if another meteorite hits this meteorite at this time, causing it to hit Xiao Yu
If so, Xiao Yu would have no time to dodge and could only be destroyed by it.
"Wealth is gained through danger. Damn it, if you do this, you will be popular and drink spicy food from now on!" Xiao Yu felt fierce in his heart, but his actions became more cautious.
Gradually, the distance has shortened to two thousand meters... one thousand meters... five hundred meters...
Just when victory was in sight, suddenly, a dark and inconspicuous figure broke into Xiao Yu's sight. Xiao Yu was shocked when he saw that figure hit the target meteorite at a relative speed of several hundred meters per second.
On the target meteorite, it exploded with a burst of fire, and then rolled up. Due to the heat of the impact, the solid water, carbon dioxide, hydrogen, oxygen, etc. on it began to volatilize violently and turned into a large ball.
Groups of fog.
Not only that, the target meteorite changed its orbit due to this impact and began to fly away in another direction, disappearing in the blink of an eye.
Xiao Yu was angry and anxious, and cursed the meteorite that had caused trouble a thousand times. After the curse was over, he started to cheer up again, turning the astronomical telescope, looking for traces of the target meteorite.
Xiao Yu knew that because of the recoil of the volatile gas and the original inertia, it could not run far. Sure enough, after Xiao Yu searched for two hours, he finally found it in the direction of the ecliptic plane, about 600 kilometers away from him.
Got it.
Xiao Yu did not dare to increase his speed too fast. He only dared to maintain the relative speed between himself and the meteorite at fifty meters per second, which is 180 miles, and slowly approached it.
The speed of one hundred and eighty miles can be regarded as lightning fast on the earth. Here, it is a compliment to say that it crawls at a snail pace. Xiao Yu ran for more than three hours before he got within three thousand meters of it again.
superior.
"Damn it, if any blind guy dares to ruin my good deeds, I will use all my energy to kill you with a laser gun." Secretly making up his mind, Xiao Yu cautiously began to approach.
The distance got closer and closer, and Xiao Yu's mind became closer and closer. Finally, the distance shrank to 280 meters!
This distance is already within the catching range of the flying claw created by Xiao Yu.
Xiao Yu aimed his gun at the target meteorite and decisively issued the launch order.
The recoil of launching the Flying Claw caused Xiao Yu's spacecraft to shake for a while. This shaking affected the accuracy of the Flying Claw. The Flying Claw flew out like a sharp arrow, but it did not hit the target meteorite, but was far away from the target.
The meteorite passed by about fifty meters away.
Xiao Yu was finally discouraged and controlled the machine to retract the flying claw, re-modified the recoil parameters, and launched again.
The failure continued. The flying claw flew past the meteorite twenty meters away.
Continue to modify the recoil parameters and continue launching.
Finally, Xiao Yu succeeded this time! The flying claw accurately hit the middle of the target meteorite. The sharp flying claw pierced the fluffy outer layer of the target meteorite, then opened and stuck inside the meteorite, firmly connecting it to Xiao Yu.
Yu's spaceship is connected.
The meteorite was hit by an external force and immediately flew in the opposite direction. The high-strength cable was stretched straight, and under the pull of the meteorite, Xiao Yu's spacecraft flew out together.
It is so wonderful to be in a weightless environment, and many things that subvert common sense will happen. If you are on the earth and you launch a flying claw at a rock, even if the flying claw catches the rock, the rock will never escape.
.This is because of the gravity of the earth.
But this is in space, and there is no gravity of the earth. The meteorite will inevitably react when it is forced. When it is hit by the flying claw, it will escape in the opposite direction. This situation is like Xiao Yu using
A rope tied himself to the tail of an arrow, and then he shot the arrow out with a bow, and then he was carried by the arrow and flew up.
This situation has long been considered by Xiao Yu, so Xiao Yu is not panicked at all. Xiao Yu does not dare to force a stop, because such force will exceed the bearing capacity of the cable and the cable will break. Xiao Yu only has one point and one point.
Use constant force to slowly reduce the kinetic energy of the target meteorite.
After spending three hours and flying almost thousands of kilometers, Xiao Yu finally subdued the meteorite. Then, Xiao Yu dragged the meteorite and slowly flew away from the ecliptic plane.
Just like a lion that quietly caught a calf in a herd, but did not dare to devour it when surrounded by cattle, but moved the calf to a place far away from the herd before starting to eat it, Xiao Yu
I don’t dare to start my feast here because it’s too dangerous.
After spending three days, Xiao Yu dragged the target meteorite to a place 40,000 kilometers away from the ecliptic plane. Within the field of vision, there was no trace of other meteorites. Looking at the delicious meal in front of him, Xiao Yu roared excitedly
