Yes, the target chosen by Chen Yue was not the famous Galileo satellite.

Jupiter has four large moons, and these four large moons are Europa to Io. They were discovered by Galileo with a very primitive telescope, and they were given the name Galilean Moons.

On the other hand, if Galileo had been able to spot them with a very primitive telescope, it would have proved that they were large enough. If it wasn't big enough, how could Galileo find out?

In fact, the smallest of the four satellites is more than 3,100 kilometers in diameter and has a mass of about 0.81% of that of Earth.

That's actually quite a lot of mass. This mass is enough for it to take on the shape of a ball. It even has its own magnetic field and atmosphere.

Huge enough mass also means that the resources on it are abundant enough. And this is extremely important for Chen Yue's follow-up plan.

Without resources, without enough gold, silver, copper, iron, calcium, iron, zinc, selenium, and without enough elements such as hydrogen, oxygen, carbon, and silicon, industrialization is simply impossible to mention.

But unfortunately, Chen Yue still had to reluctantly give up these four huge moons with rich resources, and instead chose Ganymede as the place where he came.

In total, Jupiter has nearly 100 moons. That's it, not counting the parts that are too small to be called interstellar gravel.

Of the nearly 100 moons, Europa is the largest after the four Galilean moons. But even so, its mass is only about 2.2*10^18 kilograms, which is only about 37 parts of 100 million of the earth.

This is an order of magnitude difference from the four Galileo moons. It also means that Chen Yue can obtain very few resources from it.

But there was no way, Chen Yue could only choose it. The main reason for this was that Chen Yue planned to descend the Luminous spacecraft directly on it.

The Glowing spacecraft is normally unable to land on the planet's surface. It does not have landing gear and cannot penetrate the atmosphere, and if it does, it will rub violently with the atmosphere to produce extremely high temperatures, and eventually burn itself out.

Even its structure is not strong enough to support even a landing on the surface of the moon. Put it on it directly, and its own weight will crush itself, just like a whale in the sea comes to land.

And if you don't land on the surface of the planet, you will rely solely on the landing capsule to complete the transportation between the planet's surface and the planet's orbit? It's also a bit too risky.

What to do if the landing capsule breaks? Wouldn't that just stare and wait for death? Besides, the efficiency is too low.

After thinking about it, Chen Yue had to set the ultimate goal on Ganymede.

Because Callista is small enough, gravitational low enough, and there is no atmosphere. At the risk of risking, the Glowing Confusion ship still has a good chance of landing on it without being damaged.

As for the lack of resources, we can only endure it. However, in the early stage of development, Chen Yue thought that he could not consume too many resources.

After entering Jupiter's system, the Glowing spacecraft did not slow down, but began to accelerate. Blazing flames erupted from the tail of the cylindrical ship, propelling it faster and faster, faster and faster. After a full month and a half of maneuvering and complex orbit changes, the Glowing spacecraft finally caught up with the tiny planet.

It was an irregularly shaped, magnified pebble-like planet.

It has a dark red color overall, even redder than Mars. From a distance, it looks like a red pebble.

The reason why it is so popular is funny.

The third largest moon in the Jupiter system, Europa, is not far from its orbit. Io, on the other hand, has a more violent volcanic activity, which ejects large amounts of sulfur. The jet was so violent that it was shot straight into space by Europa.

Europa was stained with the vomit and turned red.

At this moment, the Glowing spacecraft is orbiting Jupiter at a speed of about 26.5 kilometers per second.

At this rate, it takes less than 12 hours to make one orbit around Jupiter.

At the moment, although it is moving extremely fast relative to Jupiter, the speed of the Glowing spacecraft is only a pitiful 42 meters per second relative to Ganymede.

At this speed, the Glowing spacecraft could enter Callisto's orbit. It's like an artificial satellite on Earth orbiting the Earth, neither falling nor fleeing.

The Earth's orbiting speed is up to 7.9 kilometers per second. Compared to this number, Europa's orbital speed is too low and too low. But it can't be helped, it's too small and the quality is too low.

Chen Yue didn't land in a hurry, but planned to orbit it around it for a while at this speed.

"Taller of the short. You have to pick a place with more resources and land again. ”

Chen Yue thought so.

In this process, Chen Yue manipulated Xiaobai, with the cooperation of the robotic arm, to release all the satellites captured from Mars, and also let them orbit the small poor planet at a speed of tens of meters per second.

In this way, Chen Yue carefully observed this planet for a full week. In the process, Chen Yue drew a map of Europa's surface resources, and finally chose a place as his landing site.

There is a certain amount of water ice and dry ice, as well as some iron ore and copper ore. Not far from here, there are some remaining metal elements that can be mined.

Although the quantity is small and the quality is not high, it is ...... With a planet like Europa, what is the room for choice? It's good to have it.

Chen Yue was full of disgust for this place in his heart, but he had to admit that this was the best place on the entire Ganymede.

"Hey, in the end, I had to lower my requirements, and I had to settle ......."

At this moment, Chen Yue felt like an older leftover girl.

The landing module staggered down again, and Xiaobai staggered out of the cabin and began to level the road, remove large rocks, and prepare for the subsequent landing.

Europa's gravitational pull is only 0.61% of the Earth's gravity, which means that something that weighs a ton on Earth weighs only 6.1 kilograms on Callisto. This made Xiaobai proudly transform into a strong man, his small body contained infinite strength, and a large stone with a mass of more than a dozen tons could be easily lifted and then thrown far away.

After a few busy days, the landing site was finally cleared. However, Chen Yue was not in a hurry to land immediately.

In the past few days, he has been manipulating Xiaobai to renovate the site, while paying close attention to the movement in the direction of the sun.

After a long time, the wreckage planet is finally about to hit the sun.
