2265.9.27, the final departure day.

The cold Europa is empty above, the starry harbor is empty, and there is no previous busy scene. All industrial spacecraft will make way for the departure of the Earth Age.

Looking down from the astronomical observation room, you can also see various industrial indicator lights on the surface. They arrange various regular images and flash continuously.

This ancient aviation industry language will not be disturbed by electromagnetic radiation and is something that every astronaut must learn.

Seeing the time approaching minute by minute, Captain Ma whispered: "I hope our future parent star will be better than this one..."

"It should be like this in theory," a nearby assistant responded. "Our home star is brighter and more suitable for gravity."

The mass of Glitzer 581g is 3.1 times that of the earth, the radius is 1.4 times that of the earth, and the theoretical gravity is 1.08 times that of the earth, which is pretty good in any case.

However, with current observation methods, there is no way to know the specific atmospheric conditions of this planet.

"Did the results of astronomical observations come out in the solar system?" Captain Ma asked again.

"The result is that the risk of being attacked by meteorites in the solar system is about 0.7% per million, which has been reduced to the minimum level."

"Then... let's set off!"

The orders from the captain's office were soon issued to various departments.

"Countdown to start the spacecraft, ten, nine, eight..."

"Main engine starts!"

Zhang Yuanxin watched the slow heating of the nuclear engine. One high-energy microwave after another began to heat the entire device, and the plasma quickly emitted a bright light.

At this time, what they and the staff could do was very small, and at most they could only pay attention to some changes in parameters.

The artificial intelligence in the spacecraft can notice the mistakes earlier than those of them, humans.

Of course, Zhang Yuan didn't want any accident.

Soon, the core temperature of the engine room reached a high temperature of 500 million degrees.

The movement speed of plasma turbulence is also getting faster and faster.

“Five, four, three, two, one…”

He silently recited the countdown in his heart, staring at the screen without blinking.

As the last second passed, suddenly, 16 bright blue lights appeared on the stern of the spacecraft!

These blue lights are powerful plasma pulses.

The nuclear engine will start at maximum power, providing the spacecraft with three-thousandth of the acceleration every quadratic second. The entire hull emits a very slight vibration, especially in the engine room, which feels even more obvious.

Three hours later, as the space port gradually faded away, Earth Age unfolded its huge light sail.

Large lasers from the surface shine on the light sail one after another, reflecting a golden color as bright as a mirror.

There has never been such a strong reflected light on the surface of Europa. The staff on the surface saw another rising sun.

Huge cheers erupted from the sea of ​​people, and many staff members held their hands high and raised their heads to witness the great miracles in the sky.

At this moment, Senior Brother Zhao, who was sitting on the side, said softly: "A 7/1000 light speed is a great achievement in my cognitive field and requires a lot of technical support. But it is still too slow for interstellar navigation."

"There's no way..."

Zhang Yuan replied: "If the underlying theory does not break through, curvature navigation is still science fiction. If it is a small-mass spacecraft, it can accelerate to a speed of 10% by using light paths and nuclear fusion. No matter how fast our materials are, we cannot support it..."

"Do you think there will be breakthroughs in this technology in the future?"

Zhang Yuan thought for a while, "I don't know."

After a while, he said again: "It shouldn't be."

Europa's gravity is very small. In one day, the mothership broke free from its gravity and drove towards Jupiter.

The following trajectory is very complicated.

First, in the first stage, use Jupiter's gravity to make a gravitational slingshot effect and turn.

The ability to fleece with gravitational slingshots is limited, but Jupiter's average orbital radius is 13.07km/s and an average orbital radius of 5.2au. According to the current spacecraft speed, it is not a problem to fleece a little from Jupiter.

Then we entered the second stage, inside the solar system, it circumvented eight cycles with an elliptical orbit, making full use of Europa, the moon's light path device and the sun's own light to accelerate the spacecraft.

During these 8 cycles, the spacecraft will get faster and faster.

Finally, it is the third stage, head straight to "Glitzer 581".

It sounds complicated, but the artificial intelligence in the spacecraft can fully comply with this kind of computing task, so there is no need to worry too much about anything.

After all, Earth Age is a new spacecraft. All designs also fully consider the situation of long-distance navigation. The probability of errors in the short term is not high.

...

Two months later, the awake population has been compressed to 20,000, and it is still decreasing.

This part of the sober population is mainly the main staff of the spacecraft and the postgraduate students in school.

Zhang Yuan became more and more busy, unlike the original ones who had a lot of personal time. The work meetings made him dizzy.

Planned tasks have begun to be issued in the spacecraft, and he needs to learn some new things. For example, the operation and operation of a nuclear power plant is mainly responsible for the normal operation of the unit and the supervision of the control interface of the main control room, control operations, on-site operation of power station equipment and systems, etc.

"...The next time you wake up in hibernation and the population is extremely sparse, you need to take on greater responsibilities, which is equivalent to real leadership."

"The graduate students are trained for this purpose. Everyone needs to carry the burden on their shoulders."

After the meeting, his work level had risen to level 16, which was considered to be the middle and high-level manager in the spacecraft. However, Zhang Yuan did not feel happy.

He saw Li Zhendong being depressed, and went over and patted him on the shoulder: "What are you doing? You are in a bad mood? You are already at level 11 and you are considered a middle-level cadre."

Li Zhendong smiled dryly and said, "It has nothing to do with the work level. It doesn't matter if it's a little lower than your pervert. It's just... my girlfriend is hibernating, and the next time she meets, it will be hundreds of years later. I feel very bored."

Life partners do not have the right to hibernate at the same time, they only have the right to wake up almost at the same time, and the various assembly lines of the spacecraft are shrinking and they do not raise idle people.

Zhang Yuan joked: "It will affect his mood. I said that staying single is the best way to maintain high combat effectiveness."

"You are just envious and jealous!" Li Zhendong suddenly thought of something and looked like a hippie smile: "Comrade Zhang Yuan, do you know what my greatest wish in my life is?"

"What?"

"It's... before I can find a wife."

"Get out!" Zhang Yuan's face turned slightly red, "Can you find a wife be a matter?"
Chapter completed!
