Super Battleship Reborn

Chapter 4 Cosmic Scavenger The spaceship fuel in a broad sense is divided into two parts, one part is fuel, Xiao Yu uses liquid hydrogen, the other part is oxidant, Xiao Yu uses liquid oxygen.

Fuel must be burned with an oxidant added to produce power. Now, there is not much fuel left on the spacecraft, but there is still a lot of oxidizer left.

In this case, if Xiao Yu can control the spacecraft to reach Titan, the almost infinite methane on Titan can replace liquid hydrogen as Xiao Yu's current energy consumption, and after developing a controllable nuclear fusion device, the next Saturn is an inexhaustible source of nuclear fusion fuel.

At that time, Xiao Yu will have the energy to repair the spaceship, fully turn on the power, restore the powerful computing power, and even have the energy to mine minerals, manufacture new equipment, and new spaceships!

The reality made Xiao Yu extremely sigh. Titan was there, but Xiao Yu couldn't reach it. The infinite energy is there, but Xiao Yu can't go because of the lack of energy.

Liquid hydrogen liquid hydrogen, I want liquid hydrogen! Xiao Yu almost screamed in depression.

In fact, if you search again, Xiao Yu's remaining fuel can barely support the escape velocity of Mars and leave the orbit of Mars. But in that case, the remaining energy can only support the central computer for nine months.

Nine months may seem like a long time, but compared to a long space voyage, it is really fleeting.

Even if Xiao Yu recklessly escaped from the gravitational field of Mars by relying on the remaining energy, Xiao Yu's maximum sailing speed could only reach six kilometers per second. At this speed, it would take about seven years to reach Titan. In other words, Xiao Yu died halfway through.

Such a result was absolutely unacceptable to Xiao Yu.

Xiao Yu began to calculate carefully, trying to figure out another method.

If I don't fly directly to Titan, but fly towards the sun first, with the help of Venus, the sun's gravitational acceleration, my speed can reach about 8 kilometers per second, and the closer to the sun, the faster the speed, such a Come on, I only need about two months to reach the earth's orbit. Huh? By the way, there are many comets in the asteroid belt of the earth, and a lot of water is evaporated. If I can collect some water, after getting close to the sun, I can use the ionization of the sun to ionize water into oxygen and hydrogen! I have energy again!

Xiao Yu's spirit was shocked, and in the blur, Xiao Yu finally saw a little hope for life.

When approaching the sun, the fastest speed will reach 26 kilometers per second... Then it circles the sun once, and continues to accelerate with the help of Mercury's gravity. Venus just rotates to the other side of the sun, so it's not Venus, and the next is the gravity of Mars... ... Jupiter doesn't matter, I have to stay far away from Jupiter, but even if Jupiter passes by tens of millions of kilometers away, Jupiter can at least accelerate my speed by three or four kilometers per second... In this case...

Xiao Yu calculated it carefully, and his heart became more and more excited.

If I fly in the direction of the sun, go around the sun once and then go to Saturn, although the distance has increased from about 1.3 billion kilometers to Saturn, it has increased to about 1.9 billion kilometers, but my speed has improved! It can save at least five years. time! Moreover, on Earth, I can obtain liquid oxygen and liquid hydrogen, and if it is close to the sun, the solar energy is also a considerable amount, so that the fuel is also replenished!

There is one thing that is worth worrying about. Xiao Yu thought silently, In the orbit of the earth, it is very chaotic now, and I have to be prepared to be attacked by a meteorite. And the sun, the sun must also be affected by Jupiter, and the strength of the solar wind is estimated. A few levels stronger, it's also a potential danger.

Forget it, when you reach the Earth's orbit, you should leave the ecliptic plane temporarily, collect a little less water, and safety first. As for the sun, it's still not beyond the orbit of Mercury. Although the acceleration function will be less,

However, the safety factor is much larger, and the test of the thermal insulation layer is also reduced a lot.

Okay, that's it! Xiao Yu made up his mind, and after checking himself at last to make sure that the whole plan would not have too many loopholes, he gritted his teeth and started the spaceship engine.

It's like a gamble. Who knows what danger awaits? However, if you continue to gamble, there is still about 30% hope of survival. If you don't gamble, you are completely sitting still. Xiao Yu was really unwilling to make a breakthrough in controllable nuclear fusion technology, and died like this while a bright future was waiting for him. I can't tell, I have to fight anyway.

There are really too many downsides. Not to mention whether there will be new failures in the equipment during the long journey, whether it will be attacked by meteorites, whether it will be able to collect a sufficient amount of water, just talking about the heat insulation layer of the spacecraft, the original design of the spacecraft. At times, the thermal insulation layer is designed to deal with the friction of the atmosphere when landing on the planet, not designed to deal with the high temperature of the sun.

However, in such a situation, the only way is to catch the ducks on the shelves, and if it doesn't work, it will do. If you continue to fight, it is at least a living hope. Xiao Yu can't be reconciled to his own chance and coincidence. It was difficult and difficult to integrate his soul with the central computer. He finally obtained infinite life, incomparably powerful computing power and infinite energy, but before his interstellar travel started. Just die.

Looking at Mars that gradually disappeared, Xiao Yu said silently in his heart: Big Brother Mars, thank you for blocking such a powerful storm for my younger brother. When my younger brother develops technology in the future, I will definitely come back to help you make a good transformation, um, Transform into a green planet, and then release some animals on it, transforming you into a fairyland on earth.

After making a silent wish, Xiao Yu resolutely closed the telescope. In this case, saving a little is saving a little energy.

Immediately afterwards, Xiao Yu turned off most of the non-essential functions of the main control computer, leaving only a few necessary systems such as the navigation system and the radar anti-collision system, and began a bleak and long journey.

Now Mars is about 80 million kilometers away from Earth's orbit, and it will take two months for Xiao Yu to get close to Earth's orbit. After such a long-distance roaming, he returned to the original point, which made Xiao Yu very depressed.

There is also a question of relative speed here. For example, while Xiao Yu is orbiting Mars, he also revolves around the sun with Mars at a speed of about 25 kilometers per second. When Xiao Yu left Mars and flew to the sun, from the perspective of Mars, Xiao Yu flew out in a straight line along the tangent of the orbit, but from the position of the sun, Xiao Yu flew along a parabolic curve. The specific explanation is more complicated. In short, the speed of Xiao Yu approaching the sun is about eight kilometers per second, and then under the action of the sun's gravity, it will gradually accelerate, and it will take about two months to reach the earth's orbit.

In addition to making the robot in the spaceship do some necessary preparations for collecting water, the rest of the energy consumption has been reduced to a minimum, and Xiao Yu can't even calculate the data obtained from Jupiter. Depressed, in addition to allocating a few tenths of CPU usage for robots to use, Xiao Yu stared at the dark space in a daze all day.

Without the obstruction of the atmosphere, the starry sky is very clear. Xiao Yu found the trace of Tianyuan Si among countless stars.

Tianyuan 4 is the closest star to the sun that has been confirmed to have a planet, about 10.5 light-years away. Tianyuan 4 is also the next destination in Xiao Yu's space flight plan. Because Tianyuansi has been determined to have a gas giant planet with a mass of about 1.5 times Jupiter, which can provide Xiao Yu with sufficient nuclear fusion fuel, there are two asteroid belts around Tianyuansi, which can provide Xiao Yu with sufficient nuclear fusion fuel. Yu provides sufficient building materials.

Tianyuan Si. Human's first interstellar voyage. Xiao Yu stared at Tianyuan Si's figure, murmuring in his heart, and couldn't help but start to fantasize about reaching the Tianyuan Si star system. situation comes.

After looking at it for a long time, Xiao Yu recovered his thoughts and sighed with sorrow: If this trip to the sun doesn't go well, let alone going to the four galaxies in Tianyuan, even whether I can survive is a question.

During the long voyage, more than a month has passed. The meteorite blocks in the interstellar space began to increase significantly.

The current trajectory of the spacecraft has left the ecliptic. The trajectories of the planets basically fall within the ecliptic plane. Even if the earth explodes, most of the fragments of the earth are also on the ecliptic plane.

Leaving the ecliptic plane, the probability of encountering danger is reduced to a minimum.

During this more than a month, Xiao Yu controlled the robot and used the remaining materials to make a simple filter to collect ice particles, dust and other materials in the interstellar space.

Because of the principle of conservation of angular momentum, even if the earth explodes, most of its debris will orbit the sun along its original orbit, and its speed will not change much. These days, Xiao Yu has intentionally controlled his trajectory to move closer to the original Earth's trajectory, so the relative movement speed between Xiao Yu and these ice particles and dust is not very fast, only about one or two hundred meters per second. , depending on the strength of this filter, it is enough to capture them little by little.

But as a result, Xiao Yu couldn't help but sigh in his heart.

Twenty-four hours have passed since the filter was opened. But the total mass of material captured is less than one kilogram. Among them, water accounted for less than 30%.

Mosquito legs are small and meaty, take your time. Xiao Yu worked as a cosmic scavenger while manipulating his orbit closer to the Earth's orbit.
