The spaceship is built.

It has a length of 185 meters, a wingspan of 72 meters, and a height of 48 meters. It has a rear delta airfoil structure and three engines at the tail arranged in a Z-shaped layout.

Empty weight is 13,518 tons.

Full load is 30,580 tons.

Maximum speed: 0.55 times the speed of light

Endurance: 19980 hours (the engine can be turned on at maximum power)

After more than five months of running-in training, all members reached the optimal adaptation state.

The day of setting sail is getting closer and closer.

First, in the Starry Space Exploration Bureau, select the target galaxy you want to explore.

In front of the giant star map stereoscopic projection, a senior astronomy expert set several goals for them:

"You have three choices."

"Target 1: Star C174D, which is 79 light-years away from Star Bora. There are several planets distributed in this star system, but the planet observed through polarization method is a large gaseous planet. There is a probability of distribution of heavy element planets. , about 4.7%."

"Target two: P65G star 84 light-years away from Star Bra. This star has experienced a supernova explosion, but because the explosion was too violent, the size of the star is only half of the standard sun. There are many heavy element planets in this galaxy, and its development value is very high. High, but the light energy released by the star is insufficient, making transformation difficult."

"Target three: H124B, which is 105 light-years away from Star Bra. To reach this star system, your spacecraft will have to fly for about 200 years. The distance is very far... But we recommend that you go to this star system, because it is ten kilometers away from H124B. Within light years, there are three very close stars. These three stars orbit each other. They are a very rare three-sub-galaxy. Its scientific research value is very great!"

The astronomer said excitedly.

Which one should I choose?

Yun Xinghe was a little undecided, so he asked the old man in his mind.

"Don't choose any of these three goals, they are of little value."

"I suggest you go to the P654J star 108 light-years away. Five hundred years later, this galaxy was called Pandora by the Federation. Even shortly after discovering this planet, it sent an interstellar fleet there because it is on this planet. , there is intelligent life, a strange and ancient plant life, but unfortunately, the commander of that federal fleet was a fool, and they destroyed all that life...because a few soldiers died."

"This...is really stupid."

Yun Xinghe opened his eyes wide and couldn't believe it. What threat could plant life pose to humans? Why should they be destroyed?

No, I'm going to save this planet!

"Doctor, I don't think the three goals you mentioned are of great value to the Federation. I don't want to go. Can I choose a goal myself?" Yun Xinghe asked the astronomy expert.

"Child, it would be okay if you said it earlier, but it's too late now. Within 100 light years, you can only choose these three. You should know that the Federation's plan to open up the frontier is not disorderly. Take charge of one of the sectors, and now there are only three higher-value targets left in this sector for you to choose from."

Astronomy experts said that the Starry Space Exploration Bureau’s exploration plan is divided into different stages, 100 light years, 200 light years, 300 light years... Each stage has a different plan, and the sectors responsible for each administrative star will not overlap, so as to avoid A large number of detection spacecrafts swarm towards a planet, resulting in a waste of resources.

"I know, so I want to fly farther. I want to go to the P654J star 108 light-years away."

On the projected star map, Yun Xinghe pointed at the twinkling star behind a lavender nebula.

"P654J star?"

The astronomy expert was slightly stunned and said, "You want to go through the Oma Nebula and go to this galaxy?"

He shook his head and said: "Child, I don't know why you chose to go here, but you should know that there are many dangers in that thin layer of nebula. You may encounter space storms and special magnetic fields... At least for now Speaking of which, we don’t particularly recommend that you go that far away…even if the Federation will get there sooner or later.”

The astronomy expert still wanted him to see the three stars.

"Yes, doctor, we will go there sooner or later. If we don't go this year, we will go there next year or the year after that, right? Doctor, you just said that there are only three high-value targets left, and the exploration spacecraft dispatched by Bora every year It is fifty ships. Excluding those three targets, will there be 47 spacecraft next year, which can only detect low-value targets? But isn't it a waste? It takes one or two hundred years to detect the spacecraft, and it is not easy to fly to the destination. Oh my god, nothing happened?"

Yun Xinghe's expression became serious and said: "Doctor! We are not scientists, we are space explorers! We are never afraid of danger. What we are afraid of is that we will not see any reward for our efforts, and we will be full of longings, but in the end we will gain nothing... Indeed, some stars have extremes. It has high scientific value. You can launch some unmanned probes to study it carefully, but our time is also precious. We have to find habitable planets for humans. This is our first goal!"

this……

The astronomer's old face blushed slightly, and then he discussed it with the officials of the Space Exploration Bureau, and then learned about the advanced level of the "Fitian". These officials felt that it was indeed necessary to send an exploration spacecraft as a forerunner to pass through After Oma Nebula, I wanted to lay some foundations for subsequent development work, so I agreed to Yun Xinghe's request.

Feitian can go to P654J star.

"yeah!"

Yun Xinghe clapped his hands with his teammates excitedly and cheered.

…

Two weeks later.

Brastar Spaceport.

Everything is ready and the day is about to set sail.

This is a day of farewell and a sad day.

Aunt Yun Xiaoying, a strong and brave woman, hugged her sister Yun Qiaoqiao today, and both of them cried non-stop.

"Auntie, don't cry. We will definitely come back. We won't wander outside for too long. We will all come back. Auntie, please believe us!"

Yun Qiaoqiao wiped her aunt's tears, but she shed more tears herself.

Yun Xinghe stood aside in silence, with a heavy heart.

return?

This possibility is too low. The farther you go, the less likely you are to come back.

Even if they return to Planet Bora hundreds or thousands of years later, the world has changed, things and people have changed. Even if they see their aunt again, she may not be the same aunt who raised them.

How is this difference different from the difference between life, separation and death?

Yun Xinghe was not a man who shed tears easily, but at this moment, his eyes were red and tears were rolling in his eyes.

Taking two steps forward, Yun Xinghe said to his aunt: "Aunt, don't be sad. From now on, no matter how far you go, I will send you a message every once in a while to report our situation."

Yun Xiaoying pushed Yun Qiaoqiao away, turned to look at him, nodded and said, "Okay, I hope you have a safe journey and everything goes well."

Yun Xinghe nodded, remembered something, and said to her: "Aunt, my genetic genes are placed in the gene bank of the Health Hospital. After a few years, please help me take them out and find two outstanding people." I’ll use my egg cells to help cultivate two children, preferably a boy and a girl. As for the raising of the children, I’ll leave it to you, aunt!”

"Well, I will take good care of them." Yun Xiaoying nodded.

However, when she heard the word "egg cells", her classmate Mikoto Koarashi's pretty face blushed slightly. Two weeks ago, she also went to the health hospital and had an ovarian cell extraction operation, and a total of two cells were taken out. As for She also designated a "target" for the selection of paternally inherited genes, and she only told Yun Xiaoying who this target was.

But for some reason, Yun Qiaoqiao, who was still crying just now, turned her head and lowered her head quietly, her face turning into red cloth. In fact, she also went to the hospital to have the same operation, and took out two ovaries. Cell, but the chosen match, she argued with her aunt all night.

"Daughter, please don't leave. Dad, please don't leave! Dad is such a precious baby. What will Dad do if you leave?"

There was a burst of crying not far away, but it was Uehara Aika's father, a fat and bald man, with tears streaming down his face, holding his daughter's hand and refusing to let her go.

"Dad, didn't I leave two egg cells? If you want children, can you just match them? You can be the grandpa of these two children!"

However, Uehara Aika has not thought about the partner for egg cell pairing until now. TV stars, athletes, and handsome men have all considered it, but they are not very satisfied...

When she saw Yun Xinghe, her eyes lit up, she walked over and patted him on the shoulder, and said carelessly: "Hey, you should have donated more than one copy of the genes in the hospital. There must be hundreds or tens of millions." ? Lend me two, my dad wants to hold his grandson!"

Yun Xinghe sweated, "This..."

The shoulder was slapped hard again. The force of the hand was so strong that Yun Xinghe staggered. Uehara Aika was a little annoyed and said: "As a grown man, be more agile and that's it!"

She turned back to her father and said, "Dad, please take care of my two children."

"No, I don't want it! It's very hard to take care of children. They poop and pee all the time. When they grow up, they have to run away. Why is my life so miserable..."

Her father sat on the floor, crying and fussing like a child. It took a long time to coax him to peace.

…

Say goodbye to your family and everyone board the ship.

Feitian, in the bridge control room.

Supplies are fully prepared.

Everyone is in their place.

The material reactor ignites and the engine begins to warm up.

Yun Xinghe, who was in the captain's seat, first checked whether the crew on board was full before issuing the captain's order:

"Science officer?"

"Get in position!"

"helmsman?"

"Get in position!"

"Communications officer?"

"Get in position!"

"Navigation officer?"

"Get in position!"

"Weapons officer?"

"Get in position!"

"Chief Engineer?"

"Get in position!"

"Repair officer?"

"Get in position!"

"Logistics officer?"

"Get in position!"

"Medical officer?"

"Get in position!"

"The Feitian ship is full, please take off!" Yun Xinghe said to the tower commander through the radio.

"The channel has been cleared and you can take off. I wish you a smooth journey!" the tower commander replied.

"Feitian, set sail!"

Yun Xinghe shouted loudly, and the helmsman Sugaru, who was holding the operating lever, pushed forward hard. There was a slight shaking, and his back couldn't help but press against the back of the chair. Everyone raised their heads, and the spaceport outside the window was accelerating. Fall backwards.

"goodbye!"

At the space port, I bid farewell to my relatives in the area and watched the spacecraft dragging three azure tail flames fly farther and farther and smaller until it turned into a small dot like a star.

Tears burst out.
