This seems to be a good thing to decide, just follow the trail.

After all, finding the lost astronaut is Yang Meng's main goal when he came to this galaxy.

But when he thought about it, he realized that things were far from being as simple as he imagined.

"Everything is too coincidental, too deliberate!"

"Now it's just confirmed that the trail is similar to the one left over from the spaceship I was on.

But is this trail really left behind by the ship she was on? ”

Thinking of this, Yang Meng looked aside:

"Xiaoguang, apart from this wake, have you found any other anomalies on this planet?"

Hearing Yang Meng's inquiry, Xiaoguang flashed twice and responded:

"Not yet!"

Seeing that Xiao Guang didn't find it here, he asked Xiao Yin in his body again:

"Has the probe found any traces of human activity on this planet?"

"Based on the current detection data, no anomalies have been found!"

Yang Meng asked Xiao Guang and Xiao Yin about each other, and saw that they came up with the same answer.

He fell into thought,

Wake exists in the universe for a finite amount of time,

If he chooses to stay here,

Detect the planet below, maybe in a few days, and lose the trail clues,

However, if you follow the trail, the degree of exploration of Ross 128b will inevitably decline.

According to the previous inference,

She didn't leave Ross 128b until now,

That means the time that this pioneer astronaut stayed on this planet,

Most likely more than 50 years,

And a pioneer astronaut can stay on such a planet for 50 years.

If there is nothing unusual on this planet,

An ordinary person can't believe such a statement.

"In today's situation, you have to choose a focus?"

"How do you choose?"

Yang Meng looked at the data, he needed to make a decision quickly,

Fortunately, the problems he is facing today are not bipolar.

Choose one thing, and the other cannot be done at the same time,

"Can you send a probe in one direction while I explore another target?"

"But this will inevitably lead to a weakening of the detection ability in one direction!"

According to Yang Meng's thoughts at this time,

He can send a probe in the direction of the wake,

Pursue the departing spaceship, while landing on the planet Ross 128b,

Or the focus of the two is reversed,

No matter which detection direction you choose,

The direction in which the probe is sent has a much smaller detection capability than the direction in which it is detected

For example, sending probes to the planet Ross 128b,

Due to the strong convective weather above, once the detector is damaged,

Yang Meng, who has already gone to trace the trail, will no longer be able to launch a probe to explore this planet.

Or the detector can trace the trail, if the detector fails halfway, it is also a troublesome thing.

Yang Meng thought for a while, and a flash of light suddenly flashed in his head,

"Xiao Yin, how long will it take for the wake to completely dissipate?"

"At the current rate of dispersion, the wake will be able to maintain its guide pattern for about six days?"

"Six days, it should be enough!"

"Xiao Yin, determine the channel in the direction where the wake is located!"

"Let's go after the trail!"

"Understood!"

Xiaoguang on the side, seeing the expression on Yang Meng's face, had a new change, so he asked out loud:

"What's next for you?"

Yang Meng briefly told Xiaoguang about his plan, only to see Xiaoguang flicker and say:

"And what about the planet down there?"

"Don't rush the planet below!"

After dealing with Xiaoguang for a few words, Yang Meng continued to order:

"Prepare to set up a silent spy satellite, and keep the ship ready to get out of orbit!"

"Understood!"

As one command after another was issued, the spacecraft began to accelerate, slowly detaching itself from the orbit of Ross 128b.

And when the spaceship accelerates away,

A small satellite was released on the spacecraft,

The satellite did not carry any landable equipment, but instead orbited the planet Ross 128b

The satellite as a whole is dark black,

If you don't pay attention, you won't be able to detect the existence of satellites.

As the satellite was operating normally, the spacecraft also followed the trail and left the planet Ross 128b.

"Xiao Yin, continue to maintain the transmission state of the spacecraft's detection signal!"

Seeing that Yang Meng was about to give up exploring Ross 128b, the small light flickered violently a few times,

The flickering on his body seemed to be incomprehensible to Yang Meng's behavior.

"There are a lot of unique places on this planet that can be explored ......"

Seeing Xiaoguang say this, Yang Meng shook his head and said:

"But this planet has always been here, hasn't it?"

……

After leaving the orbit of the planet, the spacecraft released probes that headed forward at a faster speed.

It seems to be a pioneer probe to trace the trail ahead,

And Xiaoguang saw that Yang Meng released four detectors at one time this time,

flickered twice, showing a hint of distress,

"You're such a waste of resources!"

For the resource-starved Rutanstar civilization, wasting resources is a shameful thing.

"Launching a probe should be enough!"

Hearing Xiaoguang's words, Yang Meng shook his head and said, did not respond to Xiaoguang, but continued to give instructions to Xiao Yin:

"Get the previous spy satellite ready to land!"

And such an instruction made Xiao Yin, who has artificial intelligence, pause for half a second.

"Sorry, this spy satellite doesn't have the ability to land!"

"If it doesn't have a login function, I'll put it there!"

Thinking that Xiaoguang is artificial intelligence after all,

Yang Meng didn't explain too much, and directly gave an order:

"Spy Satellite 01, ready to enter the atmosphere of Ross 128b......"

"Attention! This command may cause satellite damage, please confirm again! ”

Yang Meng confirmed the instruction to Xiao Yin again

Xiao Yin then continued:

"Please confirm the latitude and longitude and the celestial sphere!"

"Here!"

According to the data detected before, Yang Meng quickly chose the entry point.

For terrestrial planets with strong convective environments,

There's still a place to get into.

For example, the North and South poles in the polar day, and the equatorial windless zone in special ocean areas, those places can still land.

"If it were a normal process, I would have logged in here, but now ......"

Thinking of all kinds of abnormal phenomena, Yang Meng still intends to verify a conjecture,

"According to the normal thinking of an astronaut, my final choice will also be to trace the trail of the lost astronaut, and she should know this!"

"And it's easy to think of another pioneer astronaut who went to another galaxy to come to a galaxy that wasn't his target, and what he had to do at a glance......"

"Maybe the exploration of the planet will also be started at the same time! But for the search for astronauts, exploring a planet is clearly not the point! ”

……

Time passes slowly,

A day has passed since the departure of the planet Ross 128b,

Planet B in the rear has reverted to the hemispherical shape of the former Mohu Lake,

And to see the distance of planet b is far enough,

Yang Meng gave instructions to Xiao Yin:

"Prepare to separate!"

"Understood!"

At this time, in the route map, the advance probe satellites that have flown some distance and have long disappeared in the detectable range of the spacecraft,

Several satellites that were originally lined up in a row, on the detection map, seemed to be one satellite, and suddenly split apart.

turned into several satellites and disappeared in different directions

"Attention! Ross 12802 satellite"

"Ross 12803 satellite"

"Ross 12804 satellite

"The signal has been lost!"

Watching several satellites completely disappear from the route map, in a state of complete silence that is difficult to detect,

Yang Meng sighed secretly:

"I just hope all the guesses are wrong, and at the end of this trail is her ship!"

……

In the process of Yang Meng's follow-up,

He got more data on the wake,

The wake left by the spaceship,

itself is a river with a clear stream of particles,

By judging the "flow rate" and "flow direction" of water

It's easy to find out where the ship is heading and how fast it is leaving.

The size of the ship can even be judged by the "flow" of the river.

And through these data, Yang Meng finally found something abnormal.

"Judging from the data collected these days, this trail is indeed the wake left by a large spaceship!"

"But the direction and speed at which she left!"

"Xiao Yin, can you be sure that this trail is heading in the direction of the solar system?"

"Yes!"

Hearing such an answer, Yang Meng frowned slightly,

And Xiao Guang, who was still regretting that he couldn't detect Planet 128b, saw Yang Meng's face with such an expression, and asked with a flash:

"Are you having any problems?"

"Nothing?"

Seeing Yang Meng say this, the small light continued to flicker to:

"I feel that the trail seems to be clearer, if the speed is faster, it may not be long before I can catch up with your people!"

Xiaoguang said this, his body flickered at a certain frequency to show a certain emotion,

Before, because of the regret that I couldn't detect the planet Ross 128b,

It seems to be happy to meet another human.

Yang Meng did not make any comments on Xiaoguang's positive attitude, and at this time he was still thinking about the route of the trail:

"If returning to Earth is a normal choice,"

"Judging from the trail route, the process of her departure is inevitably too impatient!"

In accordance with the normal route,

Leaving a galaxy, the initial phase is generally a spiraling process.

Instead of leaving the planet you are on, you drive in a straight line in one direction.

The reason for the spiral course is because the gravitational pull of the star will press a gravitational crater in the universe.

To get out of this big pit, you need to climb the steep slope of the pit wall.

Just like a winding road, a winding road is the safer option.

And in the universe,

A similar phenomenon will occur,

In this era, although space technology has been extremely developed,

However, for a period of time after leaving the planet, the speed of the spacecraft is not fast, and it still needs to spiral outward for a certain distance in the direction of the star's gravitational gradient.

Wait for the speed of the spacecraft to go up before it can fly in a straight line,

But Yang Meng's current wake,

Immediately after leaving the planet Ross 128b, it flew in the direction of the gravitational gradient perpendicular to it.

This is equivalent to the spacecraft directly fighting the gravitational pull of the Ross 128 star at a very low speed.

It is also equivalent to human beings riding bicycles up the mountain, not taking winding roads,

Instead, they plan to ride straight up the mountain in a straight line from the bottom of the mountain.

Although, for mankind who has mastered the technology of controlled nuclear fusion,

It's equivalent to having a nuclear-powered thigh, and it's entirely possible to pedal the bike up the hill,

But normal people will still choose the winding road. And the trail in front of him is obviously a little abnormal:

"If she's in a hurry to return to Earth......"

"No, in a hurry to return to Earth, the speed of taking the spiral route should be faster!"

"Unless...... This is done to show the way! ”

When this thought appeared in Yang Meng's mind, his expression changed somewhat,

The universe doesn't have a fixed route like a winding road,

From any direction, in any direction, you can use a spiral course to advance.

And a spaceship in this state of flight,

It is impossible to accurately determine its exact course until it leaves the star system.

Although the final course can be deduced by the spiral process,

But because it will encounter the orbits of other planets,

It is also possible for the spaceship to take advantage of the gravitational slingshot effect of the planet, or the spacecraft to be disturbed by the gravitational pull of the planet.

The speed and direction of flight will change,

These interferences make it impossible to determine the final flight direction of the spiral course.

But if the spaceship flies out of the star system in a straight line,

It is clear what it will encounter on its way, whether there are other celestial bodies interfering with its course, and the course of the spacecraft is also very easy to judge.

Especially in the Ross 128 galaxy,

Because of the existence of meteorite debris belts, there are more such interference factors, and it is difficult to analyze the final direction of the spacecraft using a spiral route.

And the direction in which the trail travels is exactly a straight line,

And in the process of leaving the Ross 128 system, it will not encounter any interference from large objects.

"This trail seems to be impatient to tell me that she is returning to the solar system!"

Yang Meng, who analyzed such a conclusion,

Yang Meng was silent for a long time,

Eventually, he decided to follow the trail and set it up on Ross 128b.

"Xiao Yin accelerates and moves forward, we should still be within the detectable field of view of Ross 128b by now!"

"Understood!"

And in the process of Yang Meng continuing to follow the trail,

A packet from the planet Ross 128b was delivered to him,

Seeing this packet from the planet Ross 128b, especially seeing a code hanging on it

Yang Meng didn't feel any surprise, but shook his head lightly and asked Xiao Yin:

"What's wrong with the spy satellite?"

"The spy satellite has lost contact!"

"Lost?"

"What caused it?"

Yang Meng began to unwrap the encrypted data packet while asking Xiao Yin,

This was the first to be sent to the Ross 128b planet moon.
