As the spaceship gets closer and closer to this ancient planet,

The above data is also becoming clearer,

And when this will enter the orbit of the planet, Yang Mengxin calmed down,

Before the tangled and complicated emotions, as if they were gone,

At this time, Yang Meng seemed to have recovered to the mentality that a normal astronaut should have.

"Whatever has happened......"

With this thought, Yang Meng checked the data transmitted by the detector,

The clearer and clearer data also made him discover the difference of this planet.

The mass of this planet is 1.36 times that of Earth

The average surface temperature is about minus 7 degrees Celsius.

This temperature is normal for a planet in the habitable zone.

After all, it's the average temperature,

Just as millionaires and ordinary people are equalized, and the per capita income will rise,

There are also cold and hot and humid regions on this planet,

It's just that compared to

The range of the Earth's maximum temperature of 71 degrees Celsius to the minimum temperature of minus 88.3 degrees Celsius,

The probe found that the ambient temperature of the planet is much more extreme than that of the Earth.

The detection data through the infrared detector shows that

Some areas of the planet can have high temperatures of more than 137 degrees, while low temperatures can be below -102 degrees.

Extreme high and low temperatures, appearing in a thick atmosphere, the result is a terrifying atmospheric circulation,

So when passing through an astronomical telescope,

Seeing the situation on this planet very clearly,

Yang Meng was not surprised to find that there were a large number of cyclones like typhoons in the clouds on this planet, and because of the strong winds, the clouds were pulled into a straight line at a certain latitude.

Extreme weather is a common problem for almost all red dwarf galaxy planets,

I think that when he was on the planet Rutan B, he had just come to the surface of the virtual environment, and he saw a scene of a frozen city.

And then I encountered the vast desert,

Rutan B may have had a suitable environment before, but now ......

"I didn't expect liquid water to exist on the surface of this planet?"

As the spaceship approaches,

Xiaoguang also saw the appearance of the planet clearly, and his body was flickering at a certain frequency, as if exuding an emotion of surprise.

"Is there anything wrong with the presence of a liquid ocean?"

Hearing such emotion, Yang Meng asked out loud,

But Xiaoguang did not answer Yang Meng's question, but flickered slightly, as if he was caught in some kind of memory,

Seeing Xiaoguang like this, he didn't ask more, but continued to check the data.

On the way from Nanhe-3 to the Ross 128 system,

The data packets sent by the Earth also contain data from other pioneer astronauts exploring other galaxies.

Because the most around the solar system are red dwarf galaxies,

Therefore, most of the targets that humans choose to explore are red dwarf galaxies.

In the course of other pioneer astronauts' expeditions to similar red dwarf galaxies,

Humans have found the presence of liquid water in the habitable zone of some red dwarfs, but have found no signs of higher life.

The root cause of this phenomenon is related to the way stars and planets move.

The Earth revolves around the Sun while still revolving.

Because of the angle of inclination, the four seasons are produced at the time of revolution,

However, in red dwarf galaxies, because the planets are too close to the star, they are affected by tidal forces, and there is a certain tidal locking phenomenon.

One of the most striking features of this phenomenon,

is the difference between the rotation time and the revolution time,

That is to say, one day on such a planet is equal to one year.

If you are born as a civilization in this environment and enter the interstellar age,

Having visited the earth in ancient times and communicated with ancient human beings, the ancients would have been amazed:

"A man came from this heaven, and one day in heaven is a year on earth!"

Perhaps the ancients did not know that it was a very common phenomenon in the universe for one day to equal one year.

And what the ancients didn't know was that under the tidal locking of the same year,

A planet will appear in an even more terrifying sight,

This planet will always face the sun with one side,

This is the source of all extreme climates, and the fact that higher life could only be described as miraculous when it came to being born on such a planet.

"But the planet in front of me ......"

Yang Meng looked at the data transmitted by the probe and was surprised to find that Planet B, which was associated with an ancient galaxy for 9.4 billion years, was not determined by the tides.

Its rotation period is 9.6 days,

The revolution period is 9.8 days,

Although there is a slight difference between the time of day and the time of year,

But it's just this little time difference,

Let this planet, not let its side always face the sun,

"Could it be that there's something disturbing that the tide locks!"

"Wait, I remember Venus and Rutan B planet ......"

Yang Meng, who thought of something, looked up the data through Xiao Yin,

Soon he found something, there are also planets in the solar system that are about to be tidally locked,

This planet is not Mercury, the closest to the Sun, but Venus, the second closest to the Sun.

Venus has a rotation period of 243 days and an orbital period of 225 days

Compared to Mercury's day of 57 days, the year is 88 days.

In this case, Venus will be tidally locked before Mercury,

But human astronomers have found that

It will take a long time for Venus to be tidally locked

Back in April 2022, an article published in the journal Nature Astronomy in that month titled:

"Atmospheric dynamics of Earth-sized planets close to tidal locking",

reveals a phenomenon that affects tidal locking.

Astronomers, discovered through long-term observations.

In a thick atmosphere,

Extremely fast atmospheric circulation can affect tidal locking,

Through the drag action of the atmosphere,

On tide-locked planets there will be a smaller jet lag of autobiographies and revolutions,

Don't underestimate this time difference, even if it's only a few hours.

But it can also make a planet break away and forever face the tragic end of the sun.

At first, human beings did not pay much attention to such research.

It wasn't until humans encountered red dwarf galaxies in the surrounding galaxies and discovered that a large number of planets were affected by tidal forces that this type of research came to mind.

And seeing such data,

Yang Meng recalled that when he left Rutan B,

He found that the entire Rutan civilization had built a complete underground gas-liquid circulation system underground.

At the beginning, he was very puzzled,

Why did the Rutan Star civilization spend tens of millions of years to build a huge project unimaginable to mankind?

Put all the liquid water areas above ground to establish a stable underground atmospheric circulation,

He left in a hurry, and he kept ignoring this question and didn't ask Xiaoguang in detail.

Now seeing the state of Ross 128b, he seems to understand something:

"Xiaoguang, you've gone through a lot of hard work to fight against Tide Lock, right?"

Hearing Yang Meng's words,

The little light flickered slightly, as if to let out a sigh:

"The planet is lucky ......"

Seeing that Xiaoguang was on the topic of luck again, Yang Meng shook his head helplessly, and then Xiaoguang continued:

"You live on a planet like that,

It is impossible to understand the terrifying effect of tidal forces on a planet, when ......"

Seeing this planet close to Rutan,

Hikaru seems to be caught up in endless memories.

It is conceivable that when a planet is close to tidal lock,

How much tribulation will be suffered by all that exists above,

Looking at the flickering little light, he suddenly felt some sympathy for the civilization born with the planet Rutan B.

"What if this happens to humans?" Yang Meng's mind suddenly popped up with such an idea,

But when you think that tidal locking is an extremely slow process, often measured in billions of years,

The Earth was locked in billions of years later, and he was completely unfounded.

Even if one day, an alien civilization uses some kind of advanced technology unknown to mankind to lock the earth in a very short period of time,

Humans can still take advantage of the phenomenon of Venus's atmospheric drag and imitate the practices of the Rutan civilization.

Let the earth end up forever towards the sun,

However, the difficulty of combining global forces to build a gas-liquid circulation system,

It seems that it is no less difficult to equip the earth with a planetary engine and let the earth wander.

……

The spacecraft continues to approach the planet Ross 128b

The probe on board the spacecraft has detected the gravitational disturbance of this planet,

According to the gravitational data from the detector,

The intelligent orbit system on the spacecraft controls the spacecraft and begins to enter the orbit of the planet Ross 128b.

Following the normal process,

He's going to send a probe to this planet, and he's going to land on this planet.

Although there is a terrifying atmospheric circulation on it, it is not impossible to make landfall.

However, not long after entering the orbit,

Xiaoguang's discovery disrupted Yang Meng's next plan.

"Little light! You mean, you've found traces left behind by the trail! ”

"Yes! A similar wake to the ship you're on! The light flickered in response.

"It can't be!"

"There's no way the ship's wake has survived until now!"

This was Yang Meng's first reaction when he heard such an answer,

It's not that he suspects that the little light can't see the wake of the ship,

Because the propulsion device used in the spacecraft is an ionic pulse thruster based on nuclear fusion energy,

Wherever the spacecraft travels, it leaves behind an exhaust band of high-energy particles.

This exhaust gas cannot be seen by the human eye,

Some human detection techniques are also unable to detect the presence of exhaust gas zones for long periods of time.

But for a special existence like Xiaoguang, the exhaust belt formed by the spacecraft is extremely obvious in its "field of vision".

In the early days, Xiaoguang communicated this imagination with Yang Meng.

And the reason why he thought that the exhaust belt left by the pioneer astronaut could not exist,

Or is it because in the empty space of the universe, high-energy particles disperse very quickly.

Even if the ion, when it leaves the thruster, it will maintain a certain loss for a long time,

But the presence of wakes is still very short, especially in galaxies.

Due to various gravitational disturbances, the wake left by the spacecraft will soon disappear.

In the case that the trail can only survive for a short time,

Considering that the pioneer astronauts who traveled to the Ross 128 system arrived here very early,

Yang Meng couldn't believe that there would be a trail of recent spacecraft activity near this planet B.

The Ross 128 galaxy is 10.89 light-years away from Earth, 1.5 light-years closer than the Rutan galaxy he is heading to.

At such a distance, the pioneer astronaut reached the Ross 128 system a few years before him.

Following the normal exploration plan,

By the time he arrived at Rutan B, the astronauts to Ross 128b had already embarked on their way back.

And in fact,

He stayed in the Rutan system for a few years, and then spent some time changing course to the Nanhe three-star system.

From the Nanhe three-star system, it took a lot of time to get to this galaxy,

These times add up to at least more than 50 years.

And this means that

If the trail is recent

The pioneer astronaut who stayed in the galaxy for more than 50 years,

And as soon as he entered the system, the pioneer astronaut drove the spacecraft away.

"How is this possible?"

"How can there be such a coincidence?"

Yang Meng, who calmed down a little, looked at Xiaoguang,

He pondered the truth or falsehood of Xiaoguang's words,

Thinking of Xiaoguang's time of time, the enthusiasm to find that pioneer astronaut was even higher than him,

Yang Meng has reason to believe that Xiaoguang has no need to deceive himself in this matter,

But to be on the safe side,

He immediately asked Xiao Yin to use a three-dimensional printing device to print out a micron detection device, a device that is not usually used.

Yang Meng had also considered this way of chasing the trail before.

But considering that the time interval was too far, he gave up this futile method,

The way to find that pioneer astronaut is to use the more commonly used and more accurate method of information detection,

But now Xiaoguang told him that there was a recent wake near Planet B,

In addition to being shocked, Yang Meng was also puzzled:

"Since she only left here recently, why didn't she find anything by means of signal detection?"

"The reason for this......

If what Xiaoguang said is true, could it be said that she kept sailing silently,

But why did she behave like this? ”

At this time, Yang Meng's heart was full of doubts.

"Is it to avoid me, or is it to avoid something?"

"Attention, the neutrino detector has been printed, waiting for the next command!"

Xiao Yin's words interrupted Yang Meng's thoughts:

"Whatever the case may be, first determine if the trail is really there?"

Thinking of this, Yang Meng and Xiaoguang once again confirmed the direction in which the trail existed

After setting the orbital parameters of the detector, the neutrino detector headed in the direction pointed by the small light.

Soon the detector sent back the data.

Looking at the data of various trivino in the data list,

Yang Meng immediately noticed that the line of data that was highlighted by Xiao Yin,

This line of data also represents the special neutrinos left behind by the human ionic nuclear dynamic pulse thruster

When we see that there is indeed such data outside planet b,

Yang Meng's first reaction was to breathe a sigh of relief,

"Whatever the case may be, she's still alive!"

Thinking of this, during the time he traveled to Ross 128b, a dark cloud that had been floating in his heart also dispersed,

"Xiao Yin, can you estimate the trail left by how long ago this was?"

"Depending on the degree of dispersion, the wake only takes more than 10 days to form!"

Hearing such an answer, Yang Meng's heart was stunned,

The next thing he has to do is make a choice.

Is he going to follow the trail of the pioneer astronaut, or is he going to continue to explore the planet below?
