"In an hour, we will leave our home, the solar system, and begin a long career of exploration, so please hurry up and take a closer look at our home."

Chennault finished briefly, and the melodious music resumed in the restaurant.

However, the four people who ate also stopped their chopsticks, and the delicious food was like chewing wax in their mouths, and they couldn't taste anything at all.

The main target of this interstellar exploration is Proxima Centauri, the closest star to the Sun.

Although it is called next to each other, the distance is at the end of the world, quite far away.

Proxima Centauri, also known as Adjac, is the third star of the Centauri α triad, also known as α Centauri C according to the Bayer nomenclature, and it is the closest star to the Sun at a distance of about 4.22 light-years.

The maximum cruising speed of the exploration fleet is one-half of the speed of light, and even if it runs wildly all the way, it will take eight and a half years to reach Proxima Centauri, and with the time of scientific research, it will be twenty years later when it returns to the solar system.

That's why the spacecraft brought so many people, even children, in order to effectively deal with all kinds of possible risks.

The other people in the restaurant were the same, they had no interest in eating, and they all got up and walked to the window, looking at the moon and the Huaxia star in the distance.

The parting is imminent, a faint sadness is diffused in the restaurant, and everyone's hearts are turning a thousand times, and they can't tell what it feels like.

If you come back after a long time, the solar system will be a different shape, right?

I just don't know if I can recognize the street in front of me when I come back.

"Report, everything is ready, please instruct!"

The loud sound of the report woke up everyone who was engrossed in looking at Huaxia Star in the flagship.

There are 51 members of the fleet command group headed by Luo Xiaoluo, commander of the fleet, Wu Huiran, chief of staff, and 121 members of the huge scientific expert group.

At the time of departure, everyone gathered in the command room to say their final goodbyes to Huaxia Star and the solar system.

Luo Xiaoluo collected his mood, let out the reluctance in his heart, and decisively ordered: "I order, all the spaceships are ready, and they will leave in five minutes!" ”

"Yes!"

Time flies, and before everyone has time to take a few more photos, five minutes have passed.

"Attention everyone, attention everyone, our ship is about to depart, our ship is about to depart!"

Chennault's radio shouting shook the spirits of the people in the restaurant, and it was finally time to leave.

Tick - Tick – Tick –

The loud and melodious sound of the sailing whistle echoed in every cabin, telling everyone that it was time to take off and leave Huaxiaxing.

All kinds of feelings are intertwined in the hearts of everyone, some people are sad and tearful, some people are open-minded smiles, there are hopes and longings, and there are also nervousness and apprehension.

There is no one in the front of Yangguan, next to each other at the end of the world, and the long voyage is a huge challenge for everyone.

All the spacecraft accelerated out of the port in turn, lined up in a bullet-shaped three-dimensional formation in space, and galloped towards Proxima Centauri.

The entire fleet consisted of a hundred ships, all of which were of the 10 million ton or more class.

Among them, 30 manned spacecraft are all 50 million tons, and each spacecraft carries between 10,000 and 30,000 people, bringing the total number of people to 600,000.

The occupations of personnel are also different, covering all occupations such as farmers, workers, teachers, soldiers, scientific researchers, etc.

This is both an exploration and a small-scale migration experiment to accumulate enough data and experience for future large-scale extragalactic development.

The others are unmanned spacecraft, with a small number of personnel on duty and vigilance, and the whole process is automatically controlled to follow the flight mode of flight.

These ships are all combat ships or material storage and transportation ships.

Needless to say, the combat spacecraft is the main force of the fleet for self-defense and counterattack, and the main force for conquest and battle is mainly based on firepower configuration.

The material storage spacecraft is not only the material carried inside the spacecraft, but also responsible for the collection of materials during the flight, emergency repairs when other spacecraft are damaged, and the production of various industrial products.

Soon, the change of sailing formation was completed, the outermost was the combat spaceship, the middle was the material spaceship, and the manned spacecraft was wrapped in it to make sure that everything was in order.

"All ships have it, release the particle sails as planned!"

After all the spaceships flew out of the spaceport and set up formations, Luo Xiaoluo gave the first order.

Like a flower blooming, layers of particle sails continue to open from the surface of the oval-shaped spacecraft, ranging from hundreds of kilometers to tens of meters.

There are countless kinds of matter in the universe, including various planets, but the universe is so big that on average there is an extreme lack of matter, and there are many places where there is no mass of matter.

Therefore, in the process of flying, it is necessary to be able to save money, and to use every cent of available matter, among which the ubiquitous particles are the most important.

Particle sails are specially developed to capture and utilize all kinds of particles in space, especially the use of visible light particles.

It would be simple to call the particle sail a different name and a solar sail.

During the 4.22 light-year voyage to Proxima Centauri, there was no apparent material available in more than 2.5 light-years of space, and during this voyage, there were various particles available from the outside.

Although the material reserves of the entire fleet can be used for a thousand years, this is only theoretical, and no one knows what damn situations will happen in a damned space voyage.

There are too many dangers from ultra-dense asteroid impacts, particle stream shocks from supernova explosions, abnormal gravitational traps, and even planetary explosions.

If you come to a serious point, you can send this seemingly powerful exploration fleet to the land of no return, and the more material you have, the more you can deal with the disaster.

So even though the particle density is very low, the spacecraft is equipped with particle sails with a total area of more than one million square kilometers.

After all, particles are everywhere and available everywhere, and once the particle sail is opened, there is no need to care about it, and it is super cost-effective.

Unbeknownst to everyone in the fleet, Wang Dao was standing in the control tower of the spaceport when the spaceship departed, and he had watched the spaceship take off.

He was supposed to give an inspirational speech, but after thinking about it, he forgot about it.

What should I say? No language pales in comparison, so it is better to burn a few more pillars of incense and pray for good luck for the fleet.

The significance of this exploration is comparable to Magellan's voyage around the earth, but Magellan died in the voyage, albeit by himself.

The final result of the round-the-world voyage was five boats, 234 people, and only one boat remained, and 18 successfully returned.

When Wang Dao personally signed and approved the plan, he knew very well that these people might never return to the solar system again.

So what does the royal road say? Silently watching them leave, waiting for them to return safely, is the only thing the king can do.
