Chapter 111

2265.9.27, final departure date.

The cold Europa is empty above, the starry harbor is empty, and there is no busy scene in the past. All industrial spacecraft will make way for the departure of the earth times.

Looking down from the astronomical observation room, you can also see various industrial indicators on the ground. They arranged various regular images, flashing constantly.

This ancient aviation language will not be disturbed by electromagnetic radiation, which is what every astronaut must learn.

Watching the time approaching, Captain Ma whispered, "I hope our future parent star is better than this one..."

"In theory, it should be." A nearby assistant responded, "our parent star is brighter and the gravity is more appropriate."

Gliese 581g's mass is 3.1 times that of the earth, its radius is 1.4 times that of the earth, and its theoretical gravity is 1.08 times that of the earth. In short, it's pretty good.

Only with the current observation means, there is no way to know the specific atmospheric conditions of the planet.

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

"As a result, the risk of being attacked by meteorites in the solar system is about 0.7 parts per million, which has been reduced to the lowest level."

"Then... Let's go!"

The command from the captain's office was soon issued to all departments.

"The spaceship starts the countdown, ten, nine, eight..."

"Main engine start!"

Zhang Yuan watched with emotion the slow warming of the nuclear engine. One after another of high-energy microwaves began to heat the whole device, and the plasma soon emitted bright light.

At this time, what they can do is very small. At most, they can only focus on the changes of some parameters.

The artificial intelligence inside the spaceship can notice the mistakes earlier than they humans.

Zhang Yuan certainly doesn't want any accident.

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

The velocity of plasma turbulence also becomes faster and faster.

"Five, four, three, two, one..."

He silently recited the countdown in his heart and stared at the screen without blinking.

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

This blue light is a powerful plasma pulse.

The nuclear engine will start at maximum power, providing the spacecraft with an acceleration of three thousandths of every second. The whole hull vibrated very slightly, especially in the engine room.

Three hours later, with the distance from the space port, the earth times launched a huge light sail.

Large lasers from the earth's surface shine on the light sail one after another, making it reflect a golden yellow as a mirror.

Europa's surface has never seen such strong reflected light. So that the staff on the surface saw another small rising sun.

Huge cheers broke out from the crowd. Many staff raised their hands and looked up to witness the great miracles in the sky.

At this time, elder martial brother Zhao, sitting on the side, said gently, "the speed of light of seven thousandths is a great achievement in my cognitive field, which needs a lot of technical support. But it's still too slow for interstellar navigation. "

"No way..."

Zhang Yuan replied: "without a breakthrough in the underlying theory, curvature navigation is still science fiction. If it is a small spacecraft, it can accelerate to 10% of the speed of light by using optical path and nuclear fusion. No matter how fast, our materials can't support... "

"Do you think there will be a breakthrough in this field in the future?"

Zhang Yuan thought, "I don't know."

After a while, he said, "probably not."

Europa's gravity is very small. In one day, the mother ship broke free of its gravity and sailed in the direction of Jupiter.

The next trajectory is very complex.

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

The ability of gravitational slingshot to roll wool is limited, but Jupiter's average revolution speed is 13.07 kms and the average orbital radius is 5.2 Au. According to the current spacecraft speed, it is not a problem to roll wool from Jupiter.

Then it entered the second stage. In the solar system, it circled in an elliptical orbit for 8 cycles, making full use of Europa, the light path device of the moon and the light of the sun itself to accelerate the spacecraft.

In these eight cycles, the speed of the spacecraft will be faster and faster.

The last is the third stage, straight to "Gliese 581".

It sounds complicated, but the artificial intelligence in the spacecraft can be fully competent for this computing task, so there is no need to worry too much.

After all, earth times is a new spacecraft. All designs also fully consider the situation of long-distance navigation. The probability of error in the short term is not large.

……

Two months later, the sober population has been reduced to 20000 and is still decreasing.

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

Zhang Yuan became more and more busy. He didn't have a lot of personal time and work meetings again and again, which made him dizzy.

The mission plan has been issued in the spacecraft. He needs to learn something new. For example, the operation of nuclear power plant is mainly responsible for the normal operation of the unit, the supervision and control operation of the control interface in the main control room, the local operation of power plant equipment and systems, etc.

"... the next time you wake up from hibernation, when the population is extremely scarce, you need to take greater responsibility, which is equivalent to the real leadership."

"Graduate students are trained for this purpose. Everyone needs to shoulder the burden. "

After the meeting, his work level has risen to level 16, which can be regarded as the middle and high level in the spacecraft. However, Zhang Yuan didn't feel happy.

He saw that Li Zhendong was depressed and patted him on the shoulder: "why, are you in a bad mood? You have reached level 11, and you can be regarded as a middle-level cadre. "

Li Zhendong said with a dry smile: "it has nothing to do with the work level. It doesn't matter if you are a little lower than a pervert like you, but... Your girlfriend is hibernating. It will be hundreds of years after the next meeting. It feels very boring."

Life partners have no right to hibernate at the same time. They only have the right to wake up almost at the same time. The ship's various assembly lines shrink and do not raise idle people.

Zhang Yuan joked: "it affects the mood. I said that staying single is the best way to maintain high combat effectiveness."

"You are envy, envy!" Li Zhendong suddenly thought of something and made a playful face: "Comrade Zhang Yuan, my greatest wish in my life, do you know what it is?"

"What?"

"Just... You can find a wife before I close my eyes."

"Get out!" Zhang Yuan's face was slightly red. "Can you count the matter of looking for his wife?"
