The spaceship is built.

With a length of 185 meters, a wingspan of 72 meters, and a height of 48 meters, the rear delta airfoil structure and the three engines at the tail are distributed in a zigzag pattern.

Empty weight 13518 tons.

Full load 30580 tons.

Max speed: 0.55 times the speed of light

Endurance: 19,980 hours (engine maximum power can be turned on)

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

The day of setting sail is getting closer and closer.

First of all, in the Star Exploration Bureau, select the target galaxy you want to explore.

Before the projection of the huge star map, a senior astronomical expert circled several goals for them:

"You have three choices. ”

"Target 1: C174D, 79 light-years away from Phora, has some planetary distributions in this star system, but the planet observed by polarization is a large gaseous planet, and the probability of a planetary distribution of heavy elements is about 4.7%. ”

"Target 2: P65G star, 84 light years away from Phora, has experienced a supernova explosion, but because the explosion is too violent, the size of the star is only half of the standard sun, there are many heavy element planets in the galaxy, and the development value is very high, but the light energy released by the star is insufficient, and it is difficult to transform. ”

"Goal 3: H124B, which is 105 light-years away from Pyrra, will take about 200 years to reach this star system, which is a very long distance...... But we recommend you to go to this galaxy, because in the vicinity of H124B star ten light-years, there are three stars that are very close to each other, these three stars orbit each other, it is a very rare triple sub-galaxy, and it has great scientific research value!"

The astronomer said with some excitement.

Which one should I choose?

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

"Don't choose any of these three goals, none of them have any value. ”

"I suggest you go to P654J, 108 light-years away, this galaxy was called Pandora by the Federation five hundred years later, and even shortly after the discovery of this planet, a starfleet was sent over, because on this planet, there is intelligent life, a strange ancient plant life, but unfortunately, the commander of that Federation fleet is an idiot, and they destroyed all these lives...... Because several soldiers died. ”

"This ...... It's stupid indeed. ”

Yun Xinghe's eyes widened, in disbelief, what threat can plant life pose to humans, why destroy them?

No, I'm going to save the planet!

"Doctor, the three goals you mentioned, I don't think they are of much value to the Federation, I don't want to go, can I choose a target by myself?" Yun Xinghe said to the astronomical expert.

"Kid, if you said it earlier, it's okay, but it's too late, within 100 light years, there are only these three left you can choose, you should know that the Federation's plan to open up the frontier is not disorderly, and Bulla Star is only responsible for one of the sectors, and now there are only three higher value targets left in this sector for you to choose from. ”

Astronomical experts said that the Star Exploration Bureau's exploration plan is divided into different stages, 100 light-years, 200 light-years, and 300 light-years...... Each stage has a different plan, and the sectors responsible for each administrative satellite will not overlap, so as to avoid a large number of exploration spacecraft flying towards one planet in a swarm, resulting in a waste of resources.

"I know, so I want to fly farther, I want to go to P654J, which is 108 light-years away. ”

On the projected star map, Yun Xinghe pointed to the twinkling star behind a lilac nebula.

"P654J star?"

The astronomical expert was slightly stunned and said, "Do you want to go through the Omar Nebula and go to this galaxy?"

He shook his head and said, "Kid, I don't know why you chose to go here, but you should know that that thin layer of nebula contains many dangers, and you may encounter space storms and special magnetic field environments...... At least for now, we don't particularly recommend going that far...... Even if sooner or later the Federation will get there. ”

In the hearts of the astronomical experts, they still wanted him to see the three substars.

"Yes, Doctor, sooner or later, I will go there, if I don't go this year, I will go next year, the year after next, right? Doctor, you just said that there are only three high-value targets left, and the spacecraft sent out by Bulla Star every year is fifty, except for those three targets, will there be 47 spacecraft next year, and they can only detect those low-value targets? But isn't this a waste, it takes one or two hundred years to probe a spacecraft, and it is not easy to fly to the destination, but there is nothing?"

Yun Xinghe's expression changed and he said seriously: "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 the return on our efforts, and we are full of longing, but we will get nothing...... It is true that some stars are of great research value, and you can send some unmanned probes to study them well, but our time is also precious, and we have to find habitable planets for mankind, which is our first goal!"

This......

The astronomer's face flushed slightly, and then he discussed with the officials of the Star Exploration Bureau, and after learning about the advanced degree of the "Feitian", these officials felt that it was indeed necessary to send a probe spacecraft as a forerunner to lay some foundation for the follow-up development work after passing through the Omar Nebula, so they agreed to the request of Yun Xinghe.

Flying space, you can go to the P654J star.

"Yay!"

Yun Xinghe clapped his teammates excitedly and cheered.

……

Two weeks later.

Brass Spaceport.

Everything is ready for the day of departure.

It's a day of parting, but also a day of sorrow.

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, no matter how long we will wander outside, we will come back, auntie, please believe us!"

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

Yun Xinghe, who was standing on the side, was silent, and his mood was heavy.

Come back?

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

Even if hundreds of years later, thousands of years later, they returned to the planet of Bolla, but even if they saw their aunt again, she might not be the aunt who raised them.

How is this distinction different from life and death?

Yun Xinghe is not a man who sheds tears easily, but at this moment, his eyes are also red, and tears are rolling in his eyes.

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

Yun Xiaoying pushed Yun Qiaoqiao away, turned her head to look at him, nodded and said, "Okay, my aunt hopes that you will have a safe journey and everything will go well." ”

Yun Xinghe nodded, remembered one thing, and said to her again: "Auntie, my genes are stored in the gene bank of the health hospital, after a few years, please help me take them out, find two excellent egg cells, and help cultivate two children, preferably a boy and a girl, as for the child's upbringing, please aunt you!"

"Well, I'll take care of them. Yun Xiaoying nodded.

However, hearing the word "egg cell", the classmate Xianglan Meiqin on the side, her pretty face turned red slightly, two weeks ago, she also went to the health hospital and did ovarian cell extraction surgery, and a total of two grains were removed, as for the selection of paternal genes, she also specified an "object", as for who this object was, she only told Yun Xiaoying.

But I don't know why, Yun Qiaoqiao, who was still crying just now, also turned her head at this time, quietly lowered her head, and her face turned into a red cloth, in fact, she also went to the hospital for that operation and took out two ovarian cells, as for the chosen partner, she quarreled with her aunt for a night.

"Daughter, don't go, Daddy begs you! Dad is such a baby as you, what should Dad do if you leave!"

There was a cry not far away, but it was Aika Uehara's father, a bald man, holding his daughter's hand with a handful of snot and tears, and didn't let her go.

"Dad, didn't I keep two eggs, if you want children, just match them with a pair? You can be the grandfather of the two children!"

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

At a glance at Yun Xinghe, her eyes lit up, she walked over and patted him on the shoulder, and said with a big grin: "Hey, you should have donated more than one genetics in the hospital, there must be hundreds of millions, right? Lend me two, my father wants to hold his grandson." ”

Yun Xinghe's head sweated, "This ......"

The shoulder was slapped again, and the strength of the hand was so strong that Yun Xinghe staggered, and Uehara Aika was a little annoyed, and said: "A big man, be a little sharp, it's so decided!"

She said to her father again: "Dad, my two children, I will trouble you to take care of them." ”

"No, I don't want it! It's hard to take care of children, a handful of and a handful of urine, and I have to run when I grow up, why is my life so miserable......"

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

……

Say goodbye to your family and board the ship.

The Flying Heavens, inside the main control room.

The supplies have long been prepared.

Everybody's in place.

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

Yun Xinghe, who was in the captain's driver's seat, confirmed whether the crew members on the boat were full before issuing the captain's instructions:

"Science officer?"

"Get in place!"

"Helmsman?"

"Get in place!"

"Communications officer?"

"Get in place!"

"Navigator?"

"Get in place!"

"Weapons officer?"

"Get in place!"

"Chief Engineer?"

"Get in place!"

"Repair officer?"

"Get in place!"

"Logistics officer?"

"Get in place!"

"Medical officer?"

"Get in place!"

"The Flying Sky is full, please take off!" Through the radio, Yun Xinghe said to the commander of the tower.

"The channel has been cleared and you can take off, I wish you all the best on your journey!" replied the tower commander.

"Fly, set sail!"

Yun Xinghe shouted, and Sugaru, the helmsman holding the operating lever, pushed forward hard, and a slight shaking sensation came, and his back was pressed against the back of the chair, everyone's heads were tilted, and the spaceport outside the window was accelerating backwards.

"Goodbye!"

"Goodbye!"

The spaceport, the relatives in the farewell area, watched the spacecraft dragging three blue tail flames fly farther and farther, and fly smaller and smaller until it becomes a small dot like a star.

Tears welled up.
