In this way, people finally avoided the inevitable "dregs" problem of digging this "big hole".
The plasma responsible for blowing away the "dregs" can also be regarded as a working fluid from another perspective. It is obviously impossible to transport so many working fluids from the orbit of Planet 3. But people chose to use local materials.
The supporting fusion power plant will also produce a lot of waste heat during the power generation process. This heat, in addition to heating the temporary residential base built here, will also have a large amount of surplus.
Originally, people would choose to discharge this waste heat directly to the asteroid. But now, they have a better place to go.
When the knives on the disk cut the rock, part of the rock will be collected by the automatic collector and then transported to the fusion power plant to cool the fusion reactor. The process of cooling fusion reactors is also the process of heating them.
So they turned into plasma and were ejected from the air outlet, blowing their "companions" into space.
In this way, no additional working fluid is required.
This is a more advanced engineering design.
At this moment, looking at the thick beam of light that appeared out of thin air from the deep earth, Zhang Longfei felt a little emotional.
He knew that some of the rubble blown out of the asteroid would directly break away from the gravity of Lakai 9352 and enter the interstellar space. But some of them don't get that high speed.
They will form a smaller version of the "asteroid belt" orbiting the star.
The total mass of this reduced version of the asteroid belt will reach about 400 million tons.
Because what people want to dig is an ultra-long channel with a length of up to 44 kilometers. All the material that originally formed this channel will be blown into space.
The excavation period for this passage is ten years. This means that on average, about 150,000 tons of matter, either in the form of plasma or in the form of solids, are blown away by this giant machine built by people every day.
Zhang Longfei suspended in space for a while, and then he could clearly see with the naked eye that the huge disc-shaped machine sank a little underground. After a day passed, the machine fell into the ground. After a month of waiting, it had sunk hundreds of meters underground.
A year later, it sank 4.4 kilometers underground. Ten years later, it had been running continuously for ten years without ever stopping for a moment. Even the maintenance only required shutting down one of the modules, and it finally stopped running.
The excavation then turned and construction work began on the horizontal surface using the remaining facilities. In the end, a huge underground cavity with a height of one hundred meters and a length and width of one kilometer was excavated.
At this moment, Zhang Longfei, who had been working here for nearly ten years, finally breathed a long sigh of relief.
He knew that building a dark matter detector, which was also the mission of a neutrino telescope, had finally completed the most important part.
Yes. This detector will be built in the center of the asteroid. The thick rock formations that make up the asteroid will serve as the thickest shield against other types of radiation.
This level of shielding is unprecedented. Because on a large planet, it is impossible for people to dig a space 44 kilometers underground. Because the star's own gravity will cause it to inevitably collapse, and even at this moment, humans have not yet developed super materials that can withstand this force.
So after research, people turned their attention to space, to an asteroid with extremely small gravity, and finally selected it.
From this, the ten-year-long excavation task of hundreds of millions of tons of material began.
Subsequently, more and larger transport spacecraft began to arrive on the planet. More construction workers began to work in the space located at the center of the earth, installing various life support, living and scientific research facilities there in a gravity-free environment.
This includes a smaller drum base, a huge tank filled with pure water, and numerous supercomputers.
The subsequent arrival of the transport spacecraft carried away the construction workers, leaving behind the scientific researchers responsible for the subsequent operation and use of the dark matter detector.
Nineteen years after the first industrial spacecraft arrived here, the largest and most accurate dark matter detector in the history of human civilization was put into operation.
Zhang Longfei left here reluctantly and headed to the next battlefield.
There, there is also a similar facility that needs him to preside over the construction.
But the difference here is that the main observation target of the other facility is the star Lakai 9352. It mainly observes neutrinos from this red dwarf star, trying to study the internal situation of this red dwarf star by observing this extremely penetrating particle, in order to obtain more scientific details about the star.
This is still of extremely important significance to the overall scientific development of human civilization.
Because the main target to be observed is the neutrinos coming from the star, the neutrino telescope must be built as close as possible to the star. The reason is simple. The further away from the star, the lower the density of neutrinos, and the less efficient the observation becomes.
But this also faces the problem of requiring a sufficiently thick shield. At this moment, there are no asteroids close to the star. However, human civilization does not have enough scientific and technological strength to directly push a qualified asteroid to pass.
The shield can only be found on Planet 1, which is closest to the star.
Planet No. 1 has been locked to Lakai 9352, and only one side will always face the star. For this planet, a day and a year are equal in length.
One thing that is counterintuitive to most people is that although Planet 1 is gravitationally locked, it is actually located in the habitable zone of Lakai 9352. The average temperature of the side facing the star is only about 29 degrees Celsius, which is just enough to maintain the existence of liquid water.
Moreover, there is a huge global ocean on it, with a water volume exceeding twenty times that of the Earth's oceans.
Sitting on the spacecraft heading to Planet No. 1, Zhang Longfei had a lot of thoughts and couldn't help but recall the scene when he participated in the feasibility discussion meeting.
"Planet 1 is too massive and has too much gravity. The neutrino telescope must be built extremely deep underground to eliminate interference as much as possible. We have reduced the requirements as much as possible, but this depth must also be reached More than 20 kilometers.”
"We don't have enough technology to dig out a depth of 20 kilometers on such a huge planet. Even if we could dig it out, our materials wouldn't be able to sustain its existence."
"This is not feasible. I suggest that this project be postponed for the time being. We can build it only after we have sufficient technological strength."
"No, the study of the internal operating mechanism of red dwarf stars is extremely important. To put it a little higher, it is related to the fate of our civilization!"
Zhang Longfei was also troubled by this problem at the time. He is very aware of the significance of this task, but he is even more aware of the difficulties faced by this task.
Finally, an idea was born in his mind.
"I remember...the ocean of Planet 1 is 21 kilometers deep at its deepest..."
Water of sufficient thickness can also serve as a qualified shelter.
Zhang Longfei's words and an inspiration made the construction task, which was almost on the verge of despair, come back from a desperate situation.
Although on this planet, the "abyss" - this is the name given to the deepest seabed by people, the water pressure there is as high as 3.2 times the water pressure of the Mariana Trench on Earth, which is more than 3,400 times that of the atmosphere. The pressure is enough to crush almost all common objects in people's lives, but in comparison, building an engineering submarine that can withstand this pressure and building a neutrino telescope base on the seabed are better than building a neutrino telescope base here. It would be many times easier to dig a 20-kilometer-deep passage on a planet.
So Zhang Longfei came.
Looking at the huge planet that is half dark and pale and half bright blue, looking at the white clouds and the huge typhoon visible to the naked eye from space covering the bright half, Zhang Longfei smiled on his face.
A special space shuttle left the transport ship and began to descend downward. After going some distance deep into the atmosphere, Zhang Longfei keenly felt that the spacecraft he was riding on had some turbulence.
The further down you go, the more severe the bumps become. Later, it even gave him the feeling of riding an off-road vehicle on the uneven surface of the planet.
But this aerospace shuttle ship was specially made, and a stability module was specially added to resist extreme weather in the atmosphere, but the result was still so bumpy.
This is enough to prove how violent the hurricane outside is at this moment.
When the space shuttle was suspended less than a hundred meters away from the surface of the sea, under the bright red stars, he truly saw the scenery unique to this planet.
At this moment, there were only two words in his mind.
Strong winds and huge waves.
That was a gale of at least level 16 according to the classification standards of the Earth Age. It was a huge wave that could even be called a tsunami, tens of meters high.
This forced the pilot of the spacecraft to raise the hull of the ship by dozens of meters to avoid being directly knocked into the sea by huge waves.
At this moment, an idea came into people's minds at the same time.
"Compared to the ocean here, in the documentary, the ocean on the earth was so docile..."
At this moment, the hull of the spacecraft was raised by more than a hundred meters again.
Zhang Longfei was a little confused and didn't know why. He looked at the display screen in front of him, clicked a few times, and found the reason.
An undersea volcano erupted, causing a tsunami. In ten minutes, waves that are almost unimaginable to humans on earth, with a height of 136 meters, will sweep across this sea area.
At this moment, the sky began to become dark without knowing when. Heavy clouds obscured the sun. Accompanied by a bolt of lightning that was countless times thicker than the earth, it was really like a downpour, no, even heavier than a downpour. An unknown amount of heavy rain poured down.
Raging storms, thunder and lightning. At this moment, this place seemed to have turned into hell. At this moment, even this space shuttle ship, which had gone through countless space journeys and was manufactured with the most advanced technology of human civilization, could not withstand it.
"Due to weather changes, we will now make an emergency evacuation. Please sit tight and fasten your seat belts..."
In the face of the power of heaven and earth, this space shuttle ship fled. The first exploration operation ended before it even started.
