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 such a large number of working fluids from the orbit of Planet 3.
It was possible. 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. In addition to heating the temporary residential base built here, this heat will also have a large amount of surplus.
Originally, people would choose to discharge this waste heat directly to this asteroid. But now, they have a better place to go.
When the knives on the disk cut the rocks, part of the rocks will be collected by the automatic collector and then transported to the fusion power plant, responsible for cooling the fusion reactor. The process of cooling the fusion reactor is also reversed.
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 needed.
This is a relatively 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 in his heart.
He knew that some of the rubble blown out of the asteroid would directly escape the gravity of Lakai 9352 and enter interstellar space. But some of it would not reach such a 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 materials that originally formed this channel will be blown into space.
The excavation period of this passage is ten years. This means that on average, about 150,000 tons of material, either in the form of plasma or in the form of solids, are used by this giant machine built by people every day.
blow away.
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 completely sank into the ground. After a month,
, it has 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 for maintenance, it only shut down one of its modules, and finally stopped.
The excavation then turned, and people began to carry out construction operations 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 become the thickest shield against other types of radiation.
This kind of shielding strength 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 if
At this moment, humans have not yet developed super materials that can withstand this force.
So after deliberation, 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 in the center of the earth, and in a gravity-free environment, various life-support systems were installed.
, living and scientific research facilities are installed there.
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 reluctantly left here and headed to the next battlefield.
There, there is also a similar facility that needs him to preside over the construction.
However, the difference here is that the main observation target of another facility is the star Lakai 9352. It mainly observes neutrinos from this red dwarf star, trying to detect this extremely penetrating
Observation of particles to study the internal conditions of this red dwarf star 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 from this star, this neutrino telescope must be built as close as possible to the star. The reason is simple. The farther away from the star, the smaller the neutrinos.
The lower the particle density, the lower the efficiency of observation.
But this will also face the problem of requiring a sufficiently thick shield. At this moment, there is no asteroid close to the star. Moreover, human civilization does not have enough scientific and technological strength to directly promote a qualified asteroid.
past.
The shield can only be found on Planet 1, which is closest to the star.
Planet No. 1 has been locked by Lakai 9352, and only one side will always face the star. For this planet, the time of a day and a year are equal.
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 29 degrees Celsius.
Right or left, 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 spaceship 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 do not have enough technology to dig out a depth of 20 kilometers on such a huge planet. Even if we can dig it out, our materials cannot sustain its existence."
"This is not feasible. I suggest that we postpone this project temporarily and wait until we have sufficient scientific and technological strength to build it."
"No, the study of the internal operating mechanism of red dwarf stars is extremely important. To put it more highly, it is related to the fate of our civilization!"
At that time, Zhang Longfei was also troubled by this problem. He was very aware of the significance of this task, but he was 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 that 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 tunnel as deep as 20 kilometers 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 covering the bright half and the huge typhoon visible to the naked eye from space, Zhang Longfei smiled on his face.
A specially designed space shuttle left the transport ship and began to descend downward. After entering the atmosphere for a certain distance, Zhang Longfei keenly felt that the spacecraft he was riding on had some turbulence.
The further down he went, the more severe the bumps became. Eventually, it even gave him the feeling of riding an off-road vehicle on the uneven surface of a planet.
But this aerospace shuttle ship was specially made, with a stabilization module specially added to resist extreme weather in the atmosphere, but the result was still so bumpy.
This is enough to prove how violent the external hurricane 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 gust of wind that was 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, with a height of tens of meters.
This forced the spacecraft pilot to raise the hull of the ship dozens of meters to avoid the fate of being knocked directly 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 100 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, a wave of 136 meters high that humans on earth could hardly imagine would sweep across the sea.
At this moment, the sky began to become dark at some point. Thick clouds covered the sun. Accompanied by a bolt of lightning that was countless times thicker than the earth, it was really like a downpour, no, worse than a downpour.
An unknown amount of heavy rain poured down.
Violent storms, thunder and lightning, and tsunamis. At this moment, this place seemed to have turned into hell. At this moment, even this space shuttle ship, which has experienced countless space journeys and is manufactured with the most advanced technology of human civilization, cannot withstand it.
.
"Due to weather changes, we will now make an emergency evacuation. Please sit still and hold yourself tight, and fasten your seat belts..."
Faced with the power of heaven and earth, this space shuttle ship fled. The first exploration operation was over before it even started.
