Super Battleship Reborn

Chapter 4 The spaceship fuel of the universe scavenger in broad sense is divided into two parts, one is fuel, Xiao Yu uses liquid hydrogen, and the other is oxidant, Xiao Yu uses liquid oxygen.

Tritium fuel must be oxidized before it can burn to generate power. Now that there is very little fuel left on the spacecraft, there are many oxidants left.

In this case, if Xiao Yu can control the spacecraft to reach Titan, almost unlimited methane on Titan can replace liquid hydrogen as Xiao Yu's current energy consumption. After the development of a controlled nuclear fusion device, Saturn is an inexhaustible source of nuclear fusion fuel.

By then, Xiao Yu had the energy to repair the spacecraft, with the power to fully open and restore powerful computing power, and even the energy to mine minerals, make new equipment, and new spacecraft!

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

"Liquid hydrogen, liquid hydrogen, I want liquid hydrogen!" Xiao Yu almost roared, almost depressed.

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

Nine months seems to be a long time, but compared to a long space flight, it is really fleeting.

萧 Even if Xiao Yu ignored the consequences and reluctantly escaped from the gravitational field of Mars, Xiao Yu could only travel at a maximum speed of six kilometers per second. At this speed, it takes about seven years to reach Titan. In other words, Xiao Yu died halfway through.

This result is absolutely unacceptable to Xiao Yu.

Xiao Xiaoyu began to calculate carefully, trying to calculate another method.

"If I do n’t fly directly to Titan, but first fly toward the sun, with the help of Earth Venus, the gravitational acceleration of the sun accelerates my speed to about eight kilometers per second, and the closer I get to the sun, the faster the speed. Come, it only takes me about two months to reach the Earth's orbit. Um? By the way, there are now many comets in the asteroid belt of the earth, and a lot of water is evaporated. If I can collect some water, close to the sun, You can use the ionization of the sun to ionize water into oxygen and hydrogen! I have energy again! "

Xiao Yu's spirit shook. In the midst of a dimness, Xiao Yu finally saw a little hope of life.

"When approaching the sun, the fastest speed will reach 26 kilometers per second ... and then orbit the sun and continue to accelerate with the help of Mercury's gravity. Venus just runs to the other side of the sun, and Venus is not considered. ... Just Jupiter, I have to be a little farther away from Jupiter, but even passing Jupiter tens of millions of kilometers away, Jupiter can at least accelerate my speed by three or four kilometers per second ... so ...

Xiao Xiaoyu thought carefully, his heart was getting more and more excited.

"If you fly towards the sun and go to Saturn once a week, although the distance has increased from about 1.3 billion kilometers directly to Saturn, to about 1.9 billion kilometers, but my speed has increased! I can save at least five years Time! And, on the earth, I can get liquid oxygen and liquid hydrogen, and if I am close to the sun, solar energy is also a considerable amount, so the fuel is also replenished! "

"It's one thing that is very worrying." Xiao Yu thought silently. "There is a lot of chaos in the earth's orbit. I want to be protected from being hit by a meteorite. There is also the sun. The sun must also be affected by Jupiter. The strength of the solar wind is estimated. It is a few levels stronger, which is also a potential danger. "

"Forget it, when you reach Earth's orbit, leave the ecliptic for the time being. Collect less water and less, safety first. As for the sun, you still don't cross Mercury's orbit. Although the acceleration function will be a little less, the safety factor It's much bigger, and the test on the insulation is much lower. "

"Okay, that's it!" Xiao Yu made up his mind and finally checked himself to make sure there weren't too many loopholes in the whole plan. He gritted his teeth and started the spacecraft engine.

This is tantamount to a gamble. God knows what dangers are waiting? However, if you continue to gamble, you still have about 30% of your hope for survival. If you don't gamble, you just sit back and wait. Xiao Yu was really unwilling to make breakthroughs in controllable fusion technology. While the bright future awaited him, he just died. Suffice it to say, we have to fight together.

I really have too many disadvantages. Not to mention that during the long journey, the equipment will not have new failures, nor will it be hit by a meteorite, and whether a sufficient amount of water can be collected. The insulation layer of the spacecraft was originally designed by the spacecraft. At that time, the heat insulation layer was designed to deal with the friction of the atmosphere when landing on the planet, but it was not designed to deal with the high temperature of the sun.

However, in such a situation, the only thing to catch the ducks is to go to the shelves. If not, it will be a hope of life. Xiao Yu was not reconciled to his chance. He had to blend the soul and the central computer in a difficult way. He finally obtained unlimited life, extremely powerful computing power, and unlimited energy, but when his interstellar travel had not yet begun Just die like that.

Watching Mars going away, Xiao Yu said silently, "Brother Mars, thank you for blocking such a strong storm for the younger brother. When the younger brother develops science and technology in the future, he will definitely come back and help you make some improvements. Well, Transform into a green planet, and release some animals on it to transform you into an adult wonderland. "

Xu silently agreed, Xiao Yu resolutely closed the telescope. In this case, you can save a little bit and save a little energy.

Soon after, 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 radar anti-collision system, and began a bleak and long journey.

Now Mars is about 80 million kilometers away from the Earth's orbit, and Xiao Yu can get close to the Earth's orbit two months later. After such a long distance roaming, the result was to return to the origin, this result made Xiao Yu depressed.

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

In addition to letting the robot inside the spacecraft begin some necessary preparations for collecting water, the rest of the energy consumption has been minimized, and Xiao Yu can't even calculate the data obtained from Jupiter. Depressed, in addition to dividing the CPU usage of a few tenths for the use of the robot, Xiao Yu looked at the dark space of the universe all day long and was dazed.

Without the obstruction of the atmosphere, the starry sky is extremely clear. Xiao Yu found traces of Tianyuan Four among countless stars.

Tiantianyuan IV is the closest star to the sun that has been identified as having a planet, about 10.5 light years away. Tianyuan IV is also the next destination in Xiao Yu's space flight plan. Because Tianyuan IV has determined that it has a gas giant giant about 1.5 times the mass of Jupiter, it can provide Xiao Yu with sufficient nuclear fusion fuel. There are two asteroid belts around Tianyuan IV, which can serve Xiao Yu provided sufficient building materials.

"Tianyuan IV. The first interstellar voyage of human beings." Xiao Yu stared at Tianyuansi's figure, muttering in his heart, unable to help but start fantasizing about reaching the Tianyuan Four Star System The situation is coming.

After reading for a long time, UU reads www.uukanshu. Xiao Yu only recovered his mind and sighed with sadness: "If the trip to the sun is not smooth, let alone go to the Tianyuan four galaxies, even if I can survive is a problem."

之中 During the long voyage, more than a month has passed. Meteorites in the interstellar space began to increase significantly.

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

When I leave the zodiac, the chance of encountering danger is minimized.

For 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 interstellar space.

Because of the 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 deliberately controlled his own 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 fast, only about one second to two hundred meters. Depending on the strength of this filter, it is enough to capture them little by little.

结果 But the result, but Xiao Yu could not help but lament in his heart.

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

"The mosquito's legs are also small meat, take your time." Xiao Yu, while controlling his orbit to move closer to the earth's orbit, did the work of a universe scavenger.
