Recalling this, Hai Ge looked around at the circular display screen in the hall and asked Cui Lunhao in confusion: "Dr. Cui, may I ask if that shining track is the triangular orbit that you have completed?" ”

Cui Lunhao was happy to get to the point quickly and replied: "Yes, in order to facilitate identification, our IT staff has colored the shape of the rail. However, the actual triangular orbit in space is invisible to the naked eye, and we can only determine whether the engineering robot has always been constructed according to the drawings and what stage the project has progressed by releasing 200,000 miniature gravitational wave detectors in the solar system. It wasn't until last month that the construction of all sections of the track was officially completed, so the probes ended their mission and were mostly scattered in space. When the batteries they carry run out of energy, they self-destruct. Of course, we also keep a small number of probes to continue to transmit images, and their service to Earth can be extended until after the Fire Man escapes the Kuiper Belt. ”

That glittering golden track is just a computer-generated three-dimensional figure. Hai Ge sighed secretly and asked again, "Then can you show me the specific location of the artificial Lagrange point of the triangular orbit?" ”

Cui Lunhao nodded, and motioned for two young people, a man and a woman, to come over, who seemed to be his assistants.

"Michelle, please switch the screen to the Kuiper tape." Choi Lun-ho said to the blonde girl with pigtails on the left.

Michelle replied "Okay", stretched out her hand and clicked a few times on the screen that Haige couldn't see, and heard a soft "bang", as if someone had opened an umbrella, but what Haige saw was not an umbrella, but a cosmic star map that occupied the entire watchtower space.

The people in the hall stayed away, and only him, Cui Lunhao and the other three stood in the star map, as if they could reach out and pick up a handful of stars from the black sea of the universe.

Looking at the familiar picture of the universe, Hai Ge was still at a loss. He had studied such holograms countless times under the guidance of success, but none of them were as real as this one. If he wasn't sure he was standing on Earth, he would have to wonder if the picture was the solar system.

Mercury and Venus were no longer visible, and the Sun was a large, dull red ball, very different from the healthy yellow dwarf that had been shown to him in the illusion, and was several times larger than the one that had been shown to him.

The only consolation was that he saw what Wedel had called a triangular orbital escape route outlined by a special fluorescent material. From a distance, it was an orange-red hue similar to light, not the blue that Wedel had suggested. The senses think it is light, but its path is crooked, reminiscent of a sheep's intestine path in the mountains.

The rails made of super metal will change shape according to the actual situation, but the guide route filled with fluorescent materials will not change, and will only go in the general direction to avoid disturbing the astronauts' line of sight.

"Little Hughne, we are standing in a thumbnail of the solar system, following this light that can turn, and we will reach the first stop of our destination, Pluto," Cui said. ”

The full name of the triangular orbit is officially named the Kuiper Route, and the earth gets rid of the existing orbit and enters the Kuiper belt, which is the first leg of the route, and the arrival station is the Kuiper station.

Haige saw the starting station of the route outside the Earth's orbit, which was close to the original International Space Station, but the position was fixed, and there was no orbital orbit.

From the outside, it was a large, slow-spinning gear, a bit like the "waterwheel" that towered in front of the Redemption Light headquarters, which converted light and heat energy into electricity.

However, it is probably because the gears are too huge, and there are countless large and small gears on its left and right sides. It is a precision transmission device, and the power comes from the cosmic radiation energy absorbed by plant metals, and as long as the universe is still there, the transmission device will not stop, so in Haige's eyes, it is more like a perpetual motion machine that human beings dream of.

"This is the space conveyor wheel, which we call the gliding elevator, and is responsible for accurately transporting the Earth following the Huoyi spacecraft to the starting coordinates. With it, the Earth will have an effective cushion as it begins to move forward, preventing the terrifying weightlessness caused by the sudden deceleration of the spaceship in the Earth's interior. You must know that no one on the earth wears a seat belt. Cui Lunhao explained vividly.

The sliding elevator is 2,300 kilometers in diameter, almost one-sixth the diameter of the Earth, and has a circumference of 7,225 kilometers, which is half the length of the elevator before the Earth reaches its intended position.

The stopping point of the Huoyiren, about 300 kilometers before the overlap point between the elevator and the orbital plane, means that the nanorope that has been successfully pulled out needs to reach a maximum of 4,000 kilometers, so that the Earth can climb to an altitude of 1,150 kilometers after the spacecraft begins to slow down at a constant speed.

Once the Earth has reached this altitude, the Hoi will be able to move 40 times faster than the Earth to make room for the Earth to enter orbit with another 1,150 kilometers.

In this process, the speed of the spacecraft can only be steadily controlled at the value of "40 times", and if it is slow, it will cause the earth to enter the space not wide enough, and if it is fast, it will cause the earth to be unbalanced.

This is indeed an extremely severe test for the astronauts who drive the spacecraft, and every step of the spacecraft must be strictly controlled to ensure the balance of the focus point, so the astronauts must be meticulous, calm and patient.

Hai Ge nodded thoughtfully, "I think this step should take the longest, as long as the earth gets out of the taxiing elevator and boards the orbit safely, the Huoyi can accelerate." If we were to travel at the speed of light, it would only take a few minutes to reach the Underworld site, and then we would be equivalent to entering the Kuiper Belt. After that, how will the route be planned? ”

Cui Lunhao said: "The new cosmic space that humans are expected to enter is the Dwarf Galaxy Canis Major, the closest to the solar system. It is far beyond the Kuiper Belt, and with the current triangular orbit construction forces of the Earth, it cannot extend to such a distant place. So after arriving at the earth's earthy station, the earth will enter a period of recuperation, and we will continue to explore new artificial Lagrange points within the Milky Way from Pluto to establish the second leg of the triangular orbit until we reach our destination. ”

"But......" Hai Ge wanted to speak and stopped, not knowing how to express the doubts in his heart.

Even if the spark of scientific exploration is passed down from generation to generation, human beings can always find artificial Lagrangian points that ensure the smooth progress of the earth, but where will the subsequent material supply come from? Is it relying on a new coalition government on the Arctic continent? ”

Cui Lunhao's lips moved, and he seemed to understand what Hai Ge wanted to ask, but he also swallowed back the words that rushed to his lips, and only said to the male assistant, "Mike, it's your turn." ”

Mike, a handsome guy with black curly hair and brown skin, made an OK gesture to Cui Lunhao, and pushed his palm to the virtual display, and the cosmic star map was partially enlarged, and Haige saw a number: U+2647.
