"It's really fortunate to say that the Pioneer Exploration Program has been running for so many years, and although there have been some minor problems during this period, there have never been any major problems!"

Yang Meng seemed to avoid the news of the loss, and recalled the space log of these years,

The pioneer astronauts who set off together seemed to be going very smoothly in the process of traveling to various galaxies, as if they were blessed with luck.

But he understands that it is not just a matter of luck that there are no major accidents.

The reason why he was able to reach the star Rutan, which is 12.36 light-years away,

In addition to the important factor of controllable nuclear fusion breakthrough and scientific and technological progress, another important factor is that human beings have extremely strict requirements for aerospace engineering.

Just like a child who travels far away, parents on earth are afraid that their children will suffer outside, and do their best to prepare bags for their children.

As for how to prepare the bags, the children who left before have written the charter for future generations with blood and tears.

As human beings leave Mother Earth and enter the universe, they see more than just colorful and spectacular cosmic scenes.

More often than not, unforeseen accidents, especially in the era before his grandfather, there was a lesson for every step taken by mankind in spaceflight.

There is a time to leave the earth,

Because a hair-thin wire has a slight change in resistance, which causes problems with the rocket attitude adjustment instrument,

Not long after the rocket took off, it crashed into the area on the side, causing a violent explosion.

As a result, several astronauts and engineers died, and a large number of aerospace work was affected, and they were seriously injured, making it difficult for them to continue their work in the aerospace field.

There are also times when you return to Earth,

Because there are tiny holes in the insulation device.

Eventually, the shuttle disintegrated during its return, and none of the astronauts on it were spared.

What's even more unacceptable is that the return process was broadcast live, and the astronaut's parents were even watching the live broadcast.

Reaching other galaxies and landing on other planets is more complicated.

Once the fragile human beings enter the universe, they are very dangerous.

Therefore, in order to carry out the Pioneer Exploration Program,

Human beings have conducted various experiments on the eight planets of the solar system.

And these experiments began in the time of Yang Meng's grandfather, and until he left the solar system, human beings were still based on the data observed by astronauts.

The new simulation environment was adapted to give the pioneer astronauts a chance to survive in a dangerous situation.

It is precisely because human beings are in the rear that they have invested a lot of time, money, and experiments.

After the pioneer astronauts left the earth, they are still conducting research and development of new technologies according to the new.

Only then can they rely on the wisdom of the entire human race to reach their respective destinations.

However, no matter how human beings prepare, in the face of the vast universe,

There will always be things that humans have never seen, accidents will always occur, and luck will disappear by then.

"It's finally there!"

"Ross 128 system!"

The content of the information that Yang Meng looked at was still difficult to calm the fluctuations in his heart, because the probability of losing contact in aerospace would mean a consequence, and he didn't want to imagine that kind of consequence.

For the astronauts who went to the Ross 128 system, he was very impressed,

Although a hundred years have passed, due to long-term low-temperature dormancy,

The time difference in his memory is not far from the memory of leaving Earth.

As pioneer astronauts, the sixteen of them have been training together for a long time, and they are very familiar with each other, so to speak, they are colleagues and friends.

"Are you still alive?"

As if sensing Yang Meng's abnormal brain fluctuations, Xiao Yi triggered a specific intelligent program and suddenly reminded aloud:

"Please note that the message is being transmitted from 12.36 light-years away!"

Yang Meng, who was originally uncomfortable in his heart, suddenly reacted when he heard such a reminder,

"12.36 light years!"

"Yes! At this point everything that should have happened has happened,

Maybe the Earth side has already received some news! ”

Yang Meng finally turned over this piece of information,

It's not because he's professionally trained, and his feelings are weak.

And under Xiao Yi's reminder, he finally woke up to the fact that no matter how much he worried about anything, there was no point.

Human communication has not been able to break through the speed of light, which means that a cluster signal from the earth will not be received until 12 years later.

And the Ross 128 galaxy is 10.9 light-years away from Earth,

It took nearly 11 years for the Ross 128 galaxy to send a message to Earth.

Therefore, it can be simply calculated that the loss of contact with the Ross 128 galaxy occurred at least 23 years ago.

And in this case everything has long been a certainty,

"It's a pity that we can't communicate directly with the astronauts heading to the Ross 128 system, otherwise, we might have been able to detect the anomaly there earlier!"

Thinking of this, Yang Meng, who was originally in a slightly calmed mood, began to feel heavy in his heart again.

But he knew how difficult it was for the pioneers to communicate directly with each other.

When I left the earth,

Some of the 16 of them also wish they could have some communication when they leave Earth,

But after careful consideration, the ground finally did not agree to the pioneer astronaut's proposal.

The reason for refusal,

Or is it because in the universe,

It is not a simple task to communicate at the speed of light between two fast-moving objects.

Whether it is neutrino cluster signal communication or electromagnetic communication.

All need a communication capsule on the spacecraft, aimed at the direction of the Earth's solar system,

The Sun, which is a yellow dwarf, is still easy to find in the range of ten light years.

In addition, the speed and trajectory of the solar system around the center of the Milky Way are very stable,

So as long as the offset is calculated,

Then point the cauldron on the signal module at a point in the direction of the solar system.

It's easy to send a cluster signal to the solar system.

And the human direction only needs to establish some signal receiving stations on various celestial bodies in the solar system.

You can receive the signal packet thrown by the astronaut.

As for the Earth side throwing packets at the pioneer astronauts,

It's simpler,

Because of the breakthrough in controlled nuclear fusion technology, the energy constraints of human beings have been reduced a lot.

Therefore, signal emission devices can be arranged at various locations in the solar system to form a large signal emission matrix.

In this way, the signal emitted covers a large sector, and the data package thrown by humans can also smoothly hit the pioneer astronauts.

However, it is still difficult for two pioneer astronauts to communicate with each other in the universe with the current level of human technology.

First of all, pioneer astronauts are not as obvious as the sun and can be easily located,

It's also not like the earth, where electricity can be squandered at will, and signal packets are squandered in the universe as if they don't need money.

These factors make it very difficult for pioneer astronauts to communicate with each other.

Of course, there is no way to communicate, and when the pioneer astronauts reach their target galaxy, they have an extremely obvious positioning coordinates, and they can try to communicate at that time.
