Chapter 5 Capture
Chapter 5 After capturing the cosmic scavenger for more than half a month, Xiao Yu realized a truth: Comets are all strong guys.
In terms of volume alone, a comet close to a star can be regarded as the largest star in the universe. The comet tail stretches out, the maximum length can reach more than 100 million kilometers, like a huge broom, sweeping the cosmic space majestically. But when you get close, you can realize how weak the comet is.
After walking through the comet's tail for more than half a month, Xiao Yu collected less than five kilograms of water. The thinness of the material in the comet's tail can be imagined. This collection efficiency made Xiao Yu extremely depressed. If Xiao Yu still had hair now, Xiao Yu would definitely grab his hair one by one in frustration.
Xiao Yu is now 30,000 kilometers above or below the ecliptic plane. Anyway, in interstellar space, it doesn't matter whether it's up or down, you can talk about it.
The so-called ecliptic plane is an imaginary plane, which can be simply understood as most of the orbits of all the planets in the star system are on a plane, and this plane is the ecliptic plane.
It's pretty close to the original Earth orbit here. Through the optical telescope, Xiao Yu could already see countless black small meteorites above, exuding heart-pounding light.
Xiao Yu has already adjusted his orbit. He intends to follow the earth's meteorite group to orbit the sun for a while. After all, collecting materials is serious, although the speed is really slow.
The lens of the optical telescope swept slowly, and an inconspicuous figure entered Xiao Yu's field of vision.
This is an irregularly shaped meteorite, about ten meters long, seven or eight meters wide, and five or six meters high. Diffuse light from nearby stars illuminated it, and then the light was collected by Xiao Yu again.
Xiao Yu's heart moved, and he immediately made some simple analysis of the meteorite. The result of the analysis immediately lifted Xiao Yu's spirit.
Analysis shows that this meteorite is about 30 percent water, 69 percent iron, and trace amounts of nitrogen, silicon, hydrogen, oxygen, potassium and other elements. Among these trace elements, most of them are hydrogen and oxygen.
"This...is this a gift from God?" Xiao Yu immediately cheered up.
This meteorite has a volume of about 400 cubic meters and a mass of more than 3,000 tons! Even if hydrogen and oxygen each account for 0.1% of their mass, the total would be as much as six tons! With so much fuel, so many things can be done.
In particular, there are more than 900 tons of water on it! This water, after getting close to the sun, can also be ionized into hydrogen and oxygen by the ionization of the sun, which is another huge income. There are more than 2,000 tons of iron, enough for Xiao Yu to repair the spacecraft.
"Capture it! Be sure to capture it!" Xiao Yu instantly made up his mind.
At this time, the star in front of the meteorite moved away, and the sun's rays directly shone on it.
Under the heat of the sun, the solid water, solid hydrogen and oxygen on the surface of the meteorite immediately began to volatilize rapidly, and fountains began to appear on the fluffy surface. Countless gaseous substances were ejected, and the entire core was shrouded in a vast white layer. In the fog, a long tail was dragged backwards.
Xiao Yu looked anxious: "These are all my treasures, they can't be evaporated like this."
Xiao Yu immediately manipulated the spacecraft to block between the meteor and the sun, and used his solar panels to withstand the heat of the sun. Without sunlight, the temperature of only a few K in interstellar space immediately cooled it, and 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 take this gift from God into his own pocket.
When a big sweet cake is in front of you, there is sufficient motivation to make cutlery and other tableware. Xiao Yu no longer cares about energy consumption and controls the robot.
I scoured the material storage room, and even dismantled some less important equipment, intending to use it as waste.
The equipment manufacturing room is Xiao Yu's most closely guarded place except for the main control room. Here, Xiao Yu collected all kinds of the most basic and important machinery to ensure that he had sufficient manufacturing power after obtaining the raw materials. Fortunately, the equipment manufacturing room was not damaged much during the previous collision between heaven and earth.
With the robot's sleepless work, a mechanical claw with a high-strength cable of about 300 meters behind it was quickly manufactured.
Xiao Yu is now only a few kilometers away from this meteorite. This distance, on an astronomical scale, is already close to each other, but it is still a little longer than Xiao Yu's capturing power. Xiao Yu had no choice but to carefully control the small spaceship, set the power of the engine to the lowest level, and slowly approached the meteorite a few meters away.
It's actually quite risky to do so. A distance of several kilometers is the shortest distance Xiao Yu can control the spacecraft to dodge. Crossing this bottom line, if another meteorite hits this meteor at this time, causing it to collide towards Xiao Yu, Xiao Yu has no time to dodge at all, and can only be destroyed by it.
"Wealth and wealth are in danger, damn, if you do this, you will eat spicy food in the future!" Xiao Yu was ruthless in his heart, but he acted more cautiously.
Gradually, the distance has been 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 the figure hit the target meteorite at a relative speed of several hundred meters per second. The target meteorite hit with a burst of fire, and then rolled over, because of the heat of the impact. , the solid water, carbon dioxide, hydrogen, oxygen, etc. above all began to volatilize violently, turning into a large cloud of fog.
Not only that, the target meteorite was changed by this impact and started to fly away in other directions, disappearing in a blink of an eye.
Xiao Yu was angry and anxious, and cursed the meteorite that caused trouble a thousand times. After the curse was over, he began to cheer up again, turning the astronomical telescope, and looking for traces of the target meteorite.
Xiao Yu knew that because of the recoil of the volatilized gas and the original inertia, it would 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.
Xiao Yu didn't dare to increase his speed too fast, he only dared to maintain the relative speed between himself and the meteor at fifty meters per second, or one hundred and eighty miles per second, and slowly approached it.
The speed of one hundred and eighty miles can be regarded as a speedy ride on earth. Here, it is a compliment to say that it is a snail crawling. Xiao Yu ran for more than three hours before he got close to the distance within 3,000 meters.
"Damn it, no matter how ignorant a guy dares to harm Lao Tzu's good deeds, Lao Tzu will use all his energy to kill you with a laser gun." After making up his mind secretly, Xiao Yu started approaching cautiously.
The distance is getting closer and closer, and Xiao Yu's mind is also getting closer and closer. Finally, the distance was reduced to 280 meters!
This distance is already within the capture range of the flying claws made by Xiao Yu.
Xiao Yu aimed the muzzle at the target meteor, and decisively issued the launch order.
The recoil of the flying claw caused Xiao Yu's spaceship to shake for a while. This shaking affected the accuracy of the flying claw. The flying claw flew out like a sharp arrow, but did not hit the target meteor, but was at a distance from the target. The meteor passed by at a distance of about fifty meters.
Xiao Yu was not discouraged, he controlled the machine to retract the flying claws, re-modified the recoil parameters, and launched again.
Continue to fail. The flying claw flew over from a place twenty meters away from the meteor.
Continue to modify the recoil parameters and continue to launch.
Finally, this time Xiao Yu succeeded! The flying claws accurately hit the middle of the target meteorite. The sharp flying claws pierced the fluffy outer layer of the target meteorite, and then opened and stuck inside the meteorite, connecting it firmly to Xiao Yu's spaceship.
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 meteor, Xiao Yu's spaceship flew out with it.
In a weightless environment, it is so wonderful, there will be many things that subvert common sense. If above the earth, you shoot a claw at a rock, and even if the claw catches the rock, the rock will never escape. This is because of the earth's gravitational pull.
But this is space, and there is no earth's gravity. When the meteorite is stressed, it will inevitably respond. It is hit by the flying claw and escapes in the opposite direction. This situation is like Xiao Yu tied himself to the end of an arrow with a rope, then shot the arrow with a bow, and then he was carried by the arrow and flew.
This situation has long been considered by Xiao Yu, so Xiao Yu is not panic at all. Xiao Yu didn't dare to stop forcibly, because that kind of force would exceed the bearing capacity of the cable and the cable would break. Xiao Yu only continued to exert little by little, slowly reducing the kinetic energy of the target meteorite.
It took a full three hours and almost flew thousands of kilometers before Xiao Yucai finally subdued the meteor. Then, Xiao Yu dragged the meteorite and slowly flew away from the ecliptic plane.
Just like a lion that quietly caught a calf in the herd, but did not dare to devour it surrounded by all the cows, but moved the calf away from the herd to start eating, Xiao Yu said. Don't dare to start your own meal here. Because it's too dangerous here.
It took three days for Xiao Yu to drag the target meteorite to a place 40,000 kilometers away from the ecliptic plane. Within the field of vision, there were no traces of other meteorites. Looking at the delicious meal in front of him, Xiao Yu roared excitedly: "Open the meal!"
