This is Xiao Yu's jihua. But this Jihua has a big loophole, and that is the problem of fuel consumption before reaching Titan.

With the current technology of the earth, the launch of spaceships is powered by rockets, reaching the second cosmic speed, after breaking free from the earth's gravitational field, the spacecraft mainly relies on inertia to fly, and the fuel carried is only used to do some fine-tuning of the orbit, as well as necessary acceleration and deceleration. Of course, this is not the case with Xiao Yu's spaceship.

Xiao Yu's spacecraft was assembled in geosynchronous orbit, and then relied on its own fuel to break free from the earth's gravitational field and set off towards outer space. Although he had stored as much fuel as possible at the beginning, Xiao Yu had also optimized the fuel utilization rate to the greatest extent, but just breaking free from the earth's gravitational field had consumed 35% of the total fuel, and he had experienced several accelerations in the middle, and now Xiao Yu was only carrying 60% of the fuel at most.

And the amount of fuel required to stay on the far side of Mars for a long time is not a small amount. Moreover, you need to slow down when you reach Mars orbit, you need to accelerate when you leave the Martian gravitational field, and you need to slow down when you reach Titan, all of which require a lot of fuel.

Originally, Xiao Yu's Jihua flew directly to Europa. Because Europa is the most likely place in the solar system where liquid water exists, apart from Earth. There is liquid water, with the help of the local special environment and some special jishu means, Xiao Yu can collect liquid hydrogen and liquid oxygen as fuel, and then concentrate on the study of nuclear fusion jishu, and wait until he fully masters the nuclear fusion engine jishu, and then collects enough fusion fuel from Jupiter, Xiao Yu will leave the solar system and fly to outer space. Now it's good haodejihua, all of them have been disturbed by the fact that the moon hit Jupiter.

In desperation, Xiao Yu adjusted the direction of the engine jet, changed the orbit, and flew towards Mars.

Nearly ten days have passed. In the meantime, the Moon has crossed the orbit of Mars, galloping towards Jupiter like a mad beast. Xiao Yu's lens is also paying close attention to the moon.

Twenty days flew by. The fiery red spark appeared in Xiao Yu's field of vision as scheduled.

After deceleration, Xiao Yu's spaceship speed had dropped to four thousand meters per second. This slowdown consumed at least five percent of the fuel, which made Xiao Yu grin distressed.

However, these costs are necessary, and if they do not slow down, the spacecraft will pass by Mars, and only when the speed is about 4,000 meters per second will it be captured by Mars and enter orbit around Mars.

Successfully entering the orbit around Mars at an altitude of 3,000 kilometers from Mars, Xiao Yu slowly rotated around Mars and began to quietly wait for the moment when the peerless impact came.

This height is the best height that Xiao Yu has carefully calculated. At this altitude, the spacecraft can be completely hidden on the back side of Mars to avoid the energy burst from the impact, and when escaping the gravitational pull of Mars, the energy consumption can be minimized.

Xiao Yu's current spacecraft is taking Mars as the center of the circle, making a circular motion similar to a circle. At Xiao Yu's current speed, it would take less than two hours to orbit Mars.

Before the Moon hit Jupiter, meteorites from Earth had already begun to visit Mars. Recently, the density and quality of meteorite impact events on Mars have been significantly improved, and looking at the flashes of light that erupted on Mars from time to time, Xiao Yu began to worry inexplicably.

Meteorite blocks from Earth clearly have features of life. For example, this meteorite, which is 300 meters long and 50 meters wide, has an albedo of as high as 0.7, and obviously has a very smooth and bright surface. Xiao Yu speculated that it could be a meteorite made mainly of steel.

Xiao Yu was greedy and wanted to get this piece of steel in his pocket. After all, it will take a lot of materials to transform the spaceship in the future. But the reality obviously disappointed Xiao Yu. Not to mention such a huge meteorite block, even if it is a small stone, Xiao Yu does not have the ability to collect it. After all, at such a high speed, a small pebble meteorite is equivalent to a grenade, and the current Xiao Yu can no longer withstand these unexpected blows.

This is also the largest meteorite in this time. The Tunguska explosion that occurred on Earth was presumed to have been caused by a meteorite about 30 meters in diameter hitting the Earth and disintegrating in the atmosphere, and the energy of that explosion was equivalent to the energy intensity of more than 1,000 Hiroshima atomic bombs. Now this steel meteorite is dozens of times larger in mass and volume than that one.

Fortunately, when the impact occurred, Xiao Yu's spacecraft happened to be on the other side of Mars. But even so, through the optical telescope, Xiao Yu also observed the huge impact of this meteorite on Mars.

The huge shock wave increased the eccentricity of Mars by 0.2 percentage points, and on the front and back of the impact point, a mountain peak as high as 10,000 meters suddenly rose, and at the same time, countless dead volcanoes on Mars began to erupt again, thick smoke and dust almost covered the entire surface of Mars, and the permafrost ice at the poles was also melted, and there was rain on Mars that had not been seen in 10,000 years. At the same time, several violent earthquakes changed almost the entire face of Mars.

Xiao Yu realized a sentence at a deeper level: "The entire solar system is an exquisite overall structure, which affects the whole body." ”

The explosion of the Earth is not just a matter of the Earth. The explosion of the earth is destined to affect the entire solar system, and it is huge, and the impact should not be underestimated.

Looking at all this, Xiao Yu felt inexplicably sad in his heart, and had a feeling of sadness for the death of a rabbit and a fox: "Now, even if there are creatures on Mars, they will die." ”

Except for nimbly dodging a few debris from the impact that flew out of Mars, the impact that occurred on Mars basically did not affect Xiao Yu. If you insist on saying it, it is to let Xiao Yu's estimation of the impact of the moon hitting Jupiter rise to another stage.

Thinking about it, Xiao Yu actually began to faintly look forward to this impact: "An impact of this level, I dare not say that the entire galaxy, at least in the third cantilever of this acre and three points of land, can be regarded as rare, right?" I can actually witness such a big event, and this life is not in vain. ”

Twenty days have passed. There are still ten days left before the estimated impact time.

Xiao Yu has begun to slowly reduce his speed, and correspondingly, in order to avoid falling into Mars due to the gravitational pull of Mars, Xiao Yu has to increase the injection power of the engine against Mars. Finally, the day before the impact, Xiao Yu fixed the spacecraft to the back side of Mars.

The current Xiao Yu is probably in a straight line with the center of mass of Mars and Jupiter. This will allow you to avoid the influence of Jupiter to the greatest extent.

Out of a kind of curiosity, Xiao Yu was really unwilling to miss the opportunity to witness a peerless impact. So, Xiao Yu put a small satellite on board the spacecraft in advance in orbit around Mars. In this way, even if Xiao Yu is hiding on the back side of Mars, he can also see some pictures of the impact through the broadcast.

In its current orbit, Mars is 500 million kilometers away from Jupiter. In other words, about half an hour after the impact occurred, the image of the impact and its effects will be transmitted here.

According to the data obtained from Zuihou's observation, Xiao Yu began to count down silently in his heart.

In fact, by this time, the impact should have already occurred. It's just that the picture of the impact has not yet traveled a long distance of 500 million kilometers. Imagining that peerless and amazing picture, Xiao Yu's heart was full of anticipation.

"Ten, nine, eight...... Two, one! ”

Everything was as expected.

Xiao Yu saw an amazing scene.

On the ecliptic, the sun's rays are almost obscured by the debris formed by the Earth's explosion. So, the solar system is dark now.

However, in the darkness, in the distant and boundless sky, a huge light source suddenly appeared, and its light intensity was almost more than ten times that of the sun! This huge light source instantly illuminates the entire solar system.

The image only appeared for a moment, and then the signal was cut off. Xiao Yu knew that it was a small moon that had been melted away by the powerful radiation from Jupiter.

Before Xiao Yu could recover from the shock, he felt the huge impact of the impact of the impact of the Moon and Jupiter.

Powerful light sources, heat sources, and high-energy rays turned Mars upside down.

The previous steel meteorite impact from the earth has made the infinite amount of dust cover the entire Martian atmosphere, so that Mars is completely covered in darkness, and the powerful energy from Jupiter attacked, and the high-energy rays directly heated the already chaotic atmosphere of Mars, and the imbalance of air pressure made a super hurricane on Mars instantly, and the wind was so strong that almost some debris was blown directly into the Martian synchronous orbit.

At the same time, the surface of Mars facing Jupiter began to melt, and the rocks, gravel, were heated into a dark red torrent that raged on the Martian ground.

In the face of the great power of heaven and earth, Xiao Yu did not dare to move at all, but silently hid on the back of Mars, silently observing all this.

Xiao Yu began to congratulate himself on the right decision. If I hadn't found the big shield of Mars, I'm afraid I would have become a puddle of molten iron by now.

The high-energy rays did not stop at all, and after passing the orbit of Mars in an instant, they continued to speed towards the Earth's orbit at the speed of light.

Right now, in the Earth's orbit, a large group of comets is converging. They are dragged back by the sun's light pressure, heat, and flow of high-energy particles. But the powerful energies from Jupiter arrived. Countless comet tails were blown away in an instant, and the sun seemed to take off its veil and brighten up at this moment. But in the next moment, the energy from Jupiter temporarily overwhelmed the energy of the sun, blowing the tails of those comets towards the sun.

Through the intensity of the comet's reflection of Jupiter's light, Xiao Yu deduced the approximate brightness of Jupiter at this moment.

At this moment, Jupiter's absolute magnitude is definitely more than ten times greater than that of the Sun! In other words, if you put Jupiter and the Sun at the same distance, Jupiter's brightness at the moment will be more than ten times higher than that of the Sun!

What a great liliang this is!
