"Satellites?"

Xiaoguang This is the first time he has come into contact with the concept of satellites,

Although their civilization made some observational techniques and made some observations of some nearby stars,

But because he can't leave his home planet,

Therefore, in astrophysics, it has not been possible to build a complete system.

The division of celestial bodies is also very vague.

So the division of the celestial bodies by the Rutans,

According to their method of observation, according to optics, the celestial bodies in the universe are very violently divided into two types: actively emitting celestial bodies and reflective celestial bodies.

And the planet's moons are themselves small,

There is also less reflected light, and even if the Rutans detect these tiny objects, they will not pay much attention.

Regarding Xiaoguang's question, Yang Meng only explained slightly,

didn't say much, but communicated with Xiao Yi about the situation of each satellite,

That huge ice giant star, in Yang Meng's current state, could not be detected,

Although humans have the means to detect giant planets, they even have the ability to land on the "nominal and unreal" of smaller giant planets

But in the current state of the Boundless East,

He does not yet have the ability to enter the outer atmosphere of an ice giant,

Unless it is a last resort, he will make such a dangerous attempt,

And now, he is more concerned about the satellite system of the ice giant.

"19 satellites have been discovered!"

"Yes, according to the data sent back by the previous detectors,

Coupled with the continued observation of the spacecraft on its way to Planet D,

It can be roughly confirmed that there are 19 large natural satellites on the planet Rutan-D! ”

"Export satellite data!"

"Understood!"

As Xiao Yi answered, a faint bioelectric signal was transmitted from Xiao Yi's chip to Yang Meng's optic nerve.

At this time, a long list also appeared in front of Yang Meng's eyes, and the list showed the data of these 19 satellites.

Looking at the content in the data, Yang Meng frowned:

"It's a little small!"

In addition to the previously discovered four spherical large moons that can maintain hydrostatic equilibrium,

The other moons are all bizarre, small satellites, like the kind of meteorites that crash into the earth.

And according to the detection, most of the main structures of these small satellites are silicates, horizontal, and low-temperature condensation solidifications of some light elements.

The content of heavy elements required by Yang Meng is extremely low, which cannot meet the mining conditions.

"It seems that we can only go to those four larger satellites to have a look!"

Thinking of these, Yang Meng and Xiao Yi re-planned the track,

Heading towards the first moon of the ice giant, the largest in this satellite system.

On the way to this satellite,

Yang Meng named the numerical codes of these satellites as simple and understandable characters.

For the sake of simplicity and memorization, Yang Meng named these satellites according to their quality, from large to small, as Icebos-I, Icebos-II, and Icebos-III......

And now he's going to Ice Deimos,

According to Xiao Yi's calculations, the distance between Icebos and the giant planet is 216,000 kilometers.

Although the distance is far less than the distance from the earth to the moon, after a series of work such as orbit change, approaching, and deceleration,

It still took nearly a day for Yang Meng to reach Bingwei.

"This satellite won't work!"

When the Infinite Orient approached Icebos,

Yang Meng immediately used a high-power searchlight device to conduct resource telemetry on Icebos.

Although his small detector has also detected the situation of Icebos before,

But just passing near the Ice Guard, there is not much data detected,

And the detection device on the small detector is small and short, and it can't penetrate the depth.

And the spacecraft has a large neutrino detection device, which can detect the depth of the satellite.

That's why Yang Meng drove the spacecraft to the vicinity of the satellite.

However, the data that has just been detected is not very optimistic for Yang Meng.

"It's like Europa, with a very thick layer of ice!"

"It seems that we can only continue to look at other satellites."

The situation of Ice Guard made Yang Meng feel that the next exploration work might not be so smooth.

……

Three days later,

Yang Meng finally completed the approach detection of the four major satellites.

And with the end of the probe,

Hopes of finding heavy elemental metals within the ice giant's satellite system seem to have been dashed.

"What's next?"

Looking at the dark gray planet below, and the huge dark blue planet behind the gray planet,

He fell into deep thought,

He thought that in the ice giant satellite system,

Even if you can't find enough heavy elements, you can always collect some of the top metal elements.

Surprisingly,

Heavy elements near the surface of the four moons of the ice giant star are very scarce.

Even if there is, it's in a deep place,

There are no conditions for mining at all.

"It seems that if you want to find a planet rich in resources, you have to be a planet with extremely active volcanic activity like Europa.

But that kind of moon is also unique in the solar system.

The probability of the existence of such a satellite in the Rutan system is not high! ”

Just as Yang Meng was thinking about what to do next, Xiao Yi's voice sounded in his head,

"Note, Probe 4 has arrived at Planet E and has returned preliminary data!"

"Planet E!" Yang Meng, who was thinking about something, heard Xiao Yi's voice, and his eyes lit up.

"It's finally here!"

Yang Meng was not surprised that it took such a long time for a small probe to reach the fourth satellite of the Rutan Galaxy.

Although Planet E is only 0.84 AU away from Rutan,

And Planet D is only 0.71 AU away from Rutan.

The straight-line distance between the two appears to be only 0.13 astronomical units, which is less than one-tenth of the average distance between Mars and Earth.

But in fact, the distance between the two planets is very far.

Because of the influence of speed and gravity, the two planets are in a strange state of orbital resonance.

It's like Pluto is often inserted into Neptune's orbit without being attracted to Neptune.

Planets D and Planets E also have special orbital periodic resonances,

In this case, Planet E will generally be on the other side of Rutan.

Therefore, after Yang Meng reached Planet D and explored for a period of time,

It was only after the small probe he launched that he crossed Rutan to reach Planet E on the other side.

"I don't know, is the situation on Planet E optimistic?"

Yang Meng calmed down and checked the data transmitted by the small detector.

However, just seeing the picture data, he was stunned:

"How can the color of this planet be green?"

As a human Yang Meng,

I've seen the blue Earth, Jupiter with wood-colored stripes, Earth-yellow Saturn, and Uranus with a strong jade color.

But this was the first time he had seen such a dark green planet.

And when he saw what was causing the whole planet to turn green, the whole person felt bad.
