"Report, the fleet has entered the edge of the solar wind, and there has been a loss of communication signal!" The Communications Officer reports to Luo Xiaoluo.

Luo Xiaoluo was very calm, and ordered: "Notify all ships to change the communication plan as planned!" ”

"Yes!"

The Exploration Fleet had been flying for almost four days, and everything was going well, but it encountered a known anomaly at the edge of the solar wind.

In the circular space with the sun as the center and the gravitational edge of the sun as the radius, many probes and reconnaissance spacecraft have been released, and according to the experience of a large number of spacecraft shuttling, it is normal for the quantum communication signal at the edge of the solar wind to be lost.

When the quantum signal is lost in the range of ten rays, the miraculous thing is that this place has no effect on the propagation of the electromagnetic signal.

A lot of scientists are working on this phenomenon, and although they don't have a clue yet, they have invested a lot of money, and everyone wants to find something out of it.

Quantum communication is theoretically safe, but it is not invulnerable, there is no such thing as invulcable in this universe, and communication problems are not a big deal.

The loss of the communication signal is not a complete failure to communicate, but a fragment is missing.

For example, a 100-word command will be conveyed with a random word missing, and the probability of each word being missed is the same, and the command is accurate only if it remains intact.

So, in order to ensure the accuracy of the command, the easiest way is to repeat the command many times, theoretically speaking, as long as it is sent twice, the probability of its accuracy can be 0.9999, and three times is 0.999999.

It is not possible to guarantee that it will be accurate, but as long as it is repeated a sufficient number of times, the command can be considered complete.

The countermeasure of the exploration fleet is to send any communication with the Huaxia Star Base Camp 10,000 times, 10,000 times, and then the CPU of the base camp will cover and compare it to get the correct message.

At the same time, the same signal is also sent through the electromagnetic wave signal for reference.

However, the electromagnetic wave is too slow, and it takes more than three or four days from the time the fleet sends electromagnetic information to the main revenue to receive the information, and with this time, the fleet has flown far away.

If you rely on electromagnetic communication, if you arrive at Proxima Centauri, if there is an accident and you need to call for help, not to mention the problem of signal loss in the process, it will be four years before you receive the message smoothly.

For such a long time, by the time the Huaxia Star Base Camp reacted, the daylilies of the exploration fleet were rotten.

Therefore, cosmic activities, especially the exploration of different star systems, must have advanced means of communication, and quantum communication is one of them, which can ignore the distance of space and reach it in an instant.

Of course, there must be other means of communication, and it is too unsafe to have only one.

"Greetings from the Solar Wind Communication Interference Research Station!" The Communications Officer reports to Luo Xiaoluo.

This has happened many times, and there are millions of spaceships active in the solar system, and exploration fleets are often used to it.

Luo Xiaoluo said calmly: "Well, reply as usual, I hope they can produce results as soon as possible and find out the reason for the loss of communication." ”

"Yes!"

Looking at the communications officer who turned around and went out, Luo Xiaoluo sighed: "There is no one in Yangguan in the west!" ”

Maybe this scientific research station is the last human celestial body they have encountered, and the next time they see the Huaxia people, I don't know when it will be waiting.

Twenty hours later, the fleet successfully crossed the edge of the solar wind, and communications returned to normal.

On the 16th exploration spacecraft, Sun Han and Luthor were sweating in the gravity training room.

"Old Sun, how is it?" Luther trembled, struggled to keep standing, and asked Sun Han breathlessly.

"Phew-" Sun Han let out a sigh and wiped the sweat from his forehead, "It's okay, you have to work hard, you can't do it after only so long." ”

The two of them had been standing still under twenty-one times gravity for more than ten minutes, Sun Han still had some strength left, but Luthor looked exhausted.

"Hey, don't say it, it's only been more than four days, and I'm bored, really, it's boring." Luthor said weakly.

He had insomnia last night, tossing and turning until about five o'clock in the morning before falling asleep, and getting up at eight o'clock.

This is the psychological fatigue of a long journey, which leads to insomnia, which is a very normal phenomenon.

Just like in the past, when people took a train on the earth for more than 12 hours, they would feel very annoyed and tired, and if they were late, even if it was an hour, it would be even more annoying and tiring, and psychological factors played an important role.

If there are noise, bumps, and tight spaces on the train due to technical reasons, then there are no such problems on the ship.

A spaceship is a residential area, all kinds of facilities are available, the weather and environment are absolutely natural, but the crew just can't help but become irritable.

"Well, if you feel uncomfortable, you can talk to Ms. Zhao, I think they enlighten you.

If it really doesn't work, you can ask her to introduce you to a girlfriend, saving you from having nothing to do all day long. Sun Han moved his body and spoke at the same time.

Ms. Zhao is the ship's doctor and is responsible for the mental health and counseling of the crew.

As a community, the ratio of men and women is basically equal, and these single people can find a girlfriend or get married, and marriage is also protected by law.

"Forget it, I don't want to see her poker face, it's boring! I'd better play more games to pass the time. Without thinking about it, Luthor rejected Sun Han's opinion and made the decision that had already been made.

Immediately, he sighed again: "But think about it, it will take four years to reach the destination, which is a long time." ”

Sun Han was also silent, it was indeed a long time!

The long journey is full of starry sky, and after watching it for four days, I feel bored, and I really don't know how to spend four years.

Sun Han stood still, crossed his hands on his hips, and said, "Don't practice, let's go see Xiaohai, and then play games together!" ”

"Good!" Luthor decisively agreed.

After saying that, the two packed up, walked out of the training ground, and went straight to the school.

If you have children, you will inevitably need a school, and the voyage will last for a long time, and children's learning cannot be relaxed.

In this cosmic era, if you don't have enough knowledge, it's basically difficult to be of great use, and you must have enough knowledge to be competent for the heavy burden.

The same goes for everyone else, the time will be filled with training and studying, and it will not be too idle.

In addition to their own professional knowledge, everyone should also have knowledge in other aspects, after all, the whole fleet is just such a small number of people.

600,000 people, which seems to be a lot, but no one dares to say that in case of accidents, these people must be enough, so it is always good to learn more, and be prepared.

Soon, the two of them ran to the school, and after greeting the teacher, they picked up Sun Xiaohai and went to the game room to play games together.

As for the study and training tasks, there is no hurry, as long as the plan is completed today, and there is no mandatory time point to complete.

The goals are clear, but the implementation process is not forced, it is a voyage away from home, and there are such and such mandatory requirements, what should we do if everyone is psychologically rebellious?
