Wandering Spaceship in Deep Space Chapter 109: Departure date

　　2265.9.27, the final departure date.

　　 The cold Europa is empty, and the starry sky harbor is empty, without the busy scene of the past. 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 indicators on the surface. They arranged various patterns of images, which kept flickering.

　　This ancient aviation industry language will not suffer any interference due to electromagnetic radiation. It is what every astronaut must learn.

　　 Watching time approaching minute by second, Captain Ma whispered: "I hope our future home planet is better than this one..."

　　"In theory, this should be the case." An assistant nearby responded, "Our home planet is brighter and more suitable for gravity."

　　 Gliese 581g has a mass 3.1 times that of the earth, a radius of 1.4 times that of the earth, and a theoretical gravity of 1.08 times that of the earth, which is not bad.

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

　　 "In the solar system, have the astronomical observation results come out?" Captain Ma asked again.

　　"The result is that the risk of meteorite attack in the solar system is about 0.7 per million, which has been reduced to a minimum."

　　 "Then... let's go!"

　　 The command of the captain's room was quickly issued to various departments.

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

　　 "The main engine starts!"

　　 Zhang Yuan watched the nuclear engine slowly warming up surgingly. High-energy microwaves one after another began to heat the entire device, and the plasma quickly emitted a bright light.

　　At this time, the things that their staff can do are very small, at most they can only pay attention to the changes of some parameters.

　　The artificial intelligence in the spacecraft can notice the mistakes earlier than humans like them.

　　 Zhang Yuan certainly does not want any accidents.

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

　　 The speed of plasma turbulence has also become faster and faster.

　　"Five, four, three, two, one..."

　　 He muttered the countdown silently in his mind, staring at the screen without blinking.

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

　　 These blue lights are just powerful plasma pulses.

The 　　 nuclear engine will start at maximum power, providing the spacecraft with an acceleration of three thousandths per second squared. The entire hull made a very slight vibration, especially in the engine room, which felt more obvious.

　　Three hours later, as it gradually moved away from the space port, the Earth Age unfolded a huge light sail.

　　The large lasers from the surface shone on the light sail one after another, making it reflect the brilliant golden yellow like a mirror.

　　 The surface of Europa has never seen such a strong reflected light. So that the staff on the surface saw another rising sun.

　　The huge cheers erupted from the crowd. Many staff members raised their hands and raised their heads to witness the great miracles in the sky.

　　 At this moment, Senior Brother Zhao, who was sitting aside, said softly: "The speed of light of seven thousandths is a great achievement in my field of cognition and requires a lot of technical support. But for interstellar navigation It's still too slow."

　　 "No way..."

　　 Zhang Yuan replied: "The underlying theory is not broken, and the curvature navigation is still sci-fi. If it is a small-mass spacecraft, using light paths and nuclear fusion, it can accelerate to 10% of the speed of light. No matter how fast our materials are, there is no way. Supported..."

　　"Do you think there will be breakthroughs in this area of ​​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. Within a day, the mothership broke free of its gravity and headed towards Jupiter.

　　The following trajectory is very complicated.

　　 In the first stage, use Jupiter's gravity to make a gravitational slingshot benefit and make a turn.

　　The gravitational slingshot has a limited ability to draw wool, but Jupiter’s average revolution speed is 13.07km/s and the average orbit radius is 5.2AU. According to the current speed of the spacecraft, it is not a problem to draw a little wool from Jupiter.

　　 then enters the second stage. Inside the solar system, an elliptical orbit is used for 8 cycles, making full use of Europa, the moon’s light path device and the sun’s own rays to accelerate the spacecraft.

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

　　 At the end is the third stage, heading straight to "Gliese 581".

　　 sounds very complicated, but the artificial intelligence in the spacecraft can fully perform this kind of computing task, so there is no need to worry too much.

　　 Earth Age is a new spacecraft after all, and all designs have fully considered the long-distance navigation, and 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 declining.

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

　　 Zhang Yuan has also become more and more busy. He doesn't have a lot of personal time like the original ~ IndoMTL.com~ Working meetings again and again, he gets confused.

　　The planned mission has already begun 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 and control operation of the control interface of the main control room, and the on-site operation of power plant equipment and systems.

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

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

　　 After this meeting, his job level has risen to level 16, and he is considered to be the middle and high level in the spacecraft. However, Zhang Yuan did not feel happy.

　　 He saw that Li Zhendong was feeling glum, and patted him on the shoulder: "What are you doing, you are in a bad mood? You are already in the eleventh grade, and you are considered a middle-level cadre."

　　 Li Zhendong said with a dry smile: "It has nothing to do with the job level, it doesn't hurt to be a little bit lower than yours, but... the girlfriend is hibernating, and the next meeting will be hundreds of years later, I feel very boring."

　　The life partner has no right to hibernate at the same time, only the right to wake up almost at the same time. The various assembly lines of the spacecraft shrink and no idlers are raised.

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

　　"You are envious, jealous!" Li Zhendong suddenly thought of something and made a hippy smile: "Comrade Zhang Yuan, do you know what is the biggest wish of my life?"

　　 "What?"

　　 "Just... before I look at you, you can find a wife."

　　 "Go!" Zhang Yuan's face turned red, "Is it possible to find a wife?"
