This is Xiao Yu's plan. But there is a big flaw in this plan, which is the problem of fuel consumption before reaching Titan.
With the earth's current technology, rockets are used to obtain power for launching spacecraft. After reaching the second cosmic speed and breaking away from the earth's gravitational field, the spacecraft mainly relies on inertia to fly, and the fuel it carries is only used to make some orbits.
Fine-tuning, as well as necessary acceleration and deceleration. Of course, this is not the case with Xiao Yu's spacecraft.
Xiao Yu's spacecraft was assembled in geosynchronous orbit, and then relied on its own fuel to break away from the earth's gravitational field and began to set off towards outer space. Although as much fuel as possible had been reserved at the beginning, Xiao Yu was not interested in fuel.
The utilization rate has also been optimized to the maximum extent, but just breaking away from the earth's gravitational field has consumed 35% of the total fuel. It has experienced several accelerations in the middle. Now the fuel carried by Xiao Yu can only be used at most.
Sixty percent of it.
The amount of fuel required to stay hidden on the backside of Mars for a long time is not a small amount. Moreover, you need to slow down when you reach the orbit of Mars, you need to accelerate when you leave the gravitational field of Mars, and you need to slow down again when you arrive at Titan. These are all
It requires a lot of fuel consumption.
Xiao Yu's original plan was to fly directly to Europa. Because Europa is the most likely place in the solar system besides the earth to have liquid water. If there is liquid water, Xiao Yu can fly directly to Europa with the help of the special local environment and some special technical means.
Xiao Yu can collect liquid hydrogen and liquid oxygen as fuel, and then concentrate on researching nuclear fusion technology. After fully mastering the nuclear fusion engine technology and collecting enough fusion fuel from Jupiter, Xiao Yu will leave the solar system and fly to outer space.
. Now all the good plans have been disrupted by the moon's collision with Jupiter.
In desperation, Xiao Yu adjusted the engine injection direction, changed the trajectory, and flew towards Mars.
Nearly ten days have passed. During this period, the moon has crossed the orbit of Mars, like a crazy beast, galloping towards Jupiter. Xiao Yu's camera is also paying close attention
Moon.
Twenty days passed by in a flash. Fiery red sparks appeared in Xiao Yu's field of vision as scheduled.
After decelerating, the speed of Xiao Yu's spacecraft has dropped to four thousand meters per second. This deceleration consumes at least 5% of the fuel, making Xiao Yu grin in pain.
However, these consumptions are necessary. If it does not slow down, the spacecraft will pass by Mars. Only when the speed is about four kilometers per second, will it be captured by Mars and enter an 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 unprecedented impact came.
This height is the optimal height calculated by Xiao Yu after precise calculations. At this height, the spacecraft can be completely hidden on the back of Mars to avoid the energy erupted by the impact, and the energy consumption can be reduced when escaping the gravity of Mars.
to the lowest.
Xiao Yu's current spacecraft is making a circular motion with Mars as the center. At Xiao Yu's current speed, it only takes less than two hours to orbit Mars.
Before the moon hits Jupiter, meteorites from the Earth have already begun to visit Mars. In recent times, the density and quality of meteorite impacts on Mars have increased significantly. Watching the meteorites erupt from time to time on Mars
Duoduo flashed, and Xiao Yu began to feel inexplicably worried.
Meteorites from the earth obviously have characteristics that life has existed on. For example, this meteorite is 300 meters long and 50 meters wide. Its albedo is as high as 0.7, and it obviously has a very smooth and bright surface. Xiao Yu
It is speculated that this may be a meteorite mainly composed of steel.
Xiao Yu was so greedy that he really wanted to put this piece of steel into his pocket. After all, transforming the spacecraft in the future would require a lot of materials. But the reality obviously disappointed Xiao Yu. Not to mention such a huge meteorite, even a meteorite
Neither Xiao Yu has the ability to collect pebbles. After all, at such a high speed, a pebble meteorite is equivalent to a grenade. Now Xiao Yu can no longer withstand these unexpected blows.
This is also the largest meteorite in this period. At first, the Tunguska explosion that occurred on the earth was speculated to be caused by a meteorite about thirty meters in diameter hitting the earth and disintegrating in the atmosphere. That explosion,
The energy is equivalent to the energy intensity of more than a thousand Hiroshima atomic bombs. The mass and volume of this steel meteorite are dozens of times larger than that one.
Fortunately, Xiao Yu's spacecraft happened to be on the other side of Mars when the impact occurred. 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. Directly behind the impact point, a mountain with a height of 10,000 meters suddenly rose. At the same time, countless dead volcanoes on Mars restarted.
After the explosion, thick smoke and dust almost covered the entire surface of Mars. The permafrost ice at the poles was also melted, and there was rainfall on Mars that had never happened in ten thousand years. At the same time, several violent earthquakes almost changed the entire appearance of Mars.
.
Xiao Yu realized a sentence on a deeper level: "The entire solar system is an exquisite overall structure, and one move 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 a huge impact that cannot be underestimated.
Looking at all this, Xiao Yu felt inexplicably sad in his heart, feeling like a rabbit dying and a fox dying: "Now, even if there are living things on Mars, they will all die."
In addition to flexibly dodging several fragments splashed from Mars by the impact, the impact on Mars basically had no impact on Xiao Yu. If I had to say it, it would have caused Xiao Yu to impact the moon.
The estimate of Jupiter's impact has risen to another level.
After thinking about it, Xiao Yu actually began to look forward to this impact: "I dare not say that such a level of impact is rare in the entire Milky Way, at least in the three-thirds of an acre of the third cantilever, right? I actually
Being able to witness such a big event, my life is not in vain."
Twenty days have passed. There are still ten days left before the estimated impact time.
Xiao Yu had begun to slowly reduce his speed. Correspondingly, in order to avoid being pulled by the gravity of Mars and falling into Mars, Xiao Yu had to increase the jet power of the engine towards Mars. Finally, one day before the impact,
Xiao Yu fixed the spacecraft on the back side of Mars.
The current Xiao Yu is roughly in a straight line with the center of mass of Mars and the center of mass of Jupiter. This can avoid the influence from Jupiter to the greatest extent.
Out of a curiosity, Xiao Yu was really unwilling to miss the opportunity to witness a unique impact. So, Xiao Yu placed a small satellite on board the spacecraft in orbit around Mars in advance. In this way, even if
Xiao Yu was hiding on the back side of Mars and could also see some scenes of the impact through the broadcast.
Calculated based on the current orbit, Mars is a full 500 million kilometers away from Jupiter. In other words, the images and effects of the impact will not be transmitted here until about half an hour after the impact occurs.
Based on the data obtained from the last observation, Xiao Yu began to count down silently in his heart.
In fact, at this time, the impact should have already occurred. It’s just that the impact scene has not traveled a long distance of 500 million kilometers. Imagining that peerless and amazing scene, Xiao Yu’s heart is full of expectations.
"Ten, nine, eight...two, one!"
Everything is as expected.
Xiao Yu saw an astonishing scene.
On the ecliptic plane, the light from the sun has been almost completely obscured by the debris formed by the explosion of the earth. Therefore, the current solar system is dark.
However, in the darkness, in the vast and distant sky, a huge light source suddenly appeared. The intensity of its light was almost ten times greater than that of the sun! This huge light source instantly illuminated the entire solar system.
This picture only appeared for a moment, and then the signal was interrupted. Xiao Yu knew that the small satellite was melted by the powerful radiation from Jupiter.
Before Xiao Yu could recover from the shock, he felt the huge impact of the collision between the moon and Jupiter.
Powerful light sources, heat sources, and high-energy rays directly turned Mars upside down.
The previous impact of steel meteorites from the earth has covered the entire Martian atmosphere with endless dust, plunging the entire planet into darkness. The powerful energy from Jupiter attacked, and the high-energy rays directly heated the already chaotic Mars.
The unbearable atmosphere and the imbalance of air pressure caused a super hurricane to blow on Mars in an instant. The wind was so strong that it almost blew some debris directly into the Mars synchronous orbit.
At the same time, the surface of the side of Mars facing Jupiter began to melt, and the rocks and gravel were heated into a dark red torrent, raging on the surface of Mars.
Facing the mighty power of heaven and earth, Xiao Yu did not dare to move at all. He just hid behind Mars silently and observed all this silently.
Xiao Yu began to feel grateful that he had made the right decision. If he had not found the big shield of Mars, he might have become a puddle of molten iron by now.
The high-energy rays did not stop at all. After passing the orbit of Mars in an instant, they continued to rush towards the orbit of the Earth at the speed of light.
There is a large group of comets gathering in the earth's orbit now. Under the influence of the sun's light pressure, heat and high-energy particle flow, they all drag their long comet tails backwards. But the powerful energy from Jupiter has arrived. Countless comets have arrived.
The comet tails were blown away in an instant, and the sun seemed to take off its veil at this moment and became brighter. But the next moment, the energy from Jupiter temporarily overwhelmed the energy of the sun, blowing away the comet tails.
Facing the sun.
Through the intensity of light reflected from Jupiter by the comet, Xiao Yu calculated the approximate brightness of Jupiter at this moment.
At this moment, the absolute magnitude of Jupiter is definitely more than ten times higher than that of the sun! In other words, if Jupiter and the sun are placed at the same distance, the brightness of Jupiter at this moment will be more than ten times higher than the sun!
