In the entire solar system, the sun alone accounts for of the mass of the entire galaxy. Of the remaining , Jupiter alone accounts for about 71%. Only 29% of the mass remains, which makes up the remaining seven major planets, as well as numerous dwarf planets, an almost endless number of asteroids, comets, interstellar dust and other celestial bodies. Jupiter has a large satellite system, and there are four satellites that have achieved hydrostatic equilibrium and are spherical. The largest satellite, Ganymede, is even larger than Mercury, a large planet, though its mass is only half that of Mercury. In addition to four large satellites, it has more than seventy small satellites and a magnificent Jovian ring. Jupiter's rings are similar to the asteroid belt in the solar system, consisting of countless large and small pieces of debris. Jupiter's rings are highly fragmented. The largest celestial body inside has a diameter of only about 100 meters, and its overall thickness is only about ten to several dozen kilometers. But this means one benefit, that is, Li Qingsong can collect minerals from Jupiter's rings very conveniently. Just look at which small celestial body's elemental composition meets your needs and directly take it away, crush it and smelt it. This completely saves you from the hassle of mining like on a planet, which requires digging downwards, even several thousand meters deep. In addition to Jupiter's rings, the other four large satellites and more than seventy small satellites also have rich mineral reserves. And most importantly, three of the four large satellites have extremely abundant water reserves.
The amount of water stored in Ganymede alone exceeds that of the entire Earth. And Li Qingsong's large-scale development just happened to require a lot of water. When on Luoshen and Dishen, Li Qingsong was often troubled by the shortage of water resources. Also, Jupiter is located right on the edge of the boundary between the rocky planets and the gaseous planets in the solar system. Here, inward is the asteroid belt of the solar system, which has more objects, dwarf planets, asteroids, etc. Further inward is Mercury, Earth, Venus and Mercury, and outward is Saturn, Uranus and Neptune. No matter what kind of resources you need, you can get them easily. No matter where you want to go, the distance is not far. This can probably be considered the "center" of a solar system. After comprehensively comparing the data of various planets, Li Qingsong finally decided to set up the main development base in the Jupiter system, and more specifically, in Ganymede. After entering the inner solar system, Li Qingsong's fleet did not stop sailing. It was not until they passed the orbits of Uranus and Saturn and were only hundreds of millions of kilometers away from Jupiter that the huge fleet slowly turned around, started its engines, and began to spray towards Jupiter, slowly reducing its speed. However, one aerospace carrier did not slow down. Not only that, it adjusted its orbit, separated from the main force, and began to move deeper into the solar system. After slowing down for more than three months, Li Qingsong's main fleet just arrived at Ganymede, and the speed just dropped to about kilometers per second. Then, 49 aerospace motherships and dozens of heavy transport ships entered the orbit around Ganymede and began to slowly revolve around it. At this moment, a magical scene appeared before Li Qingsong. The sun in the distance is no longer just a point structure, but has a certain circular structure. But it's still small, only the size of a marble. Although small, it is extremely bright, and even a little dazzling if viewed directly with the naked eye. Its brightness is enough to illuminate the vast space. With its light, you can even clearly see the small words on the book. It is even easier to cast shadows of various objects. Overall, its brightness is roughly similar to twilight on Earth. Under the shining of such a bright sun, next to it is a huge planet with obvious yellow and white stripes, which is so large that it almost occupies a large part of the celestial sphere. It was like the eyes of a starry sky demon, quietly staring at Li Qingsong's fleet, bringing an extremely strong sense of oppression.
A little further away, there is a long curved structure that is like a rainbow, extremely bright and gorgeous. It extends from the back of Jupiter like a long river in the sky, extending all the way to the extremely high sky, and then falls from a very distant place and falls again on the other side of Jupiter. This is Jupiter's ring. Next to the Jupiter rings that are as magnificent as the Milky Way, there are many bright spots of light. Those are the rest of Jupiter's moons. Turning his sight away from the sky and looking downward, Li Qingsong saw a huge pale planet. On that pale earth, there were many grayish-white stripes. This is the final destination of my voyage of more than 10 billion kilometers, Ganymede. It appears pale because much of its surface is covered in water ice, just as Earth appears blue because much of it is covered in ocean water. Those pale streaks are huge cracks in the ice. Such a huge planet with abundant water resources and other resources is now presented in front of Li Qingsong like a juicy dish. Li Qingsong was not in a hurry to land on a large scale right now. He controlled the huge fleet to remain in orbit, then sent out numerous satellites to survey the entire planet's topography, environment, and resource reserves from all angles, and also sent out many small landing spacecraft to land in advance for on-site surveys. After all, the previous exploration was too rough. Now we still need to conduct a comprehensive exploration. In addition to Ganymede, Li Qingsong also dispatched numerous satellites and scientific research vessels to different satellites to carry out the most detailed observations of each satellite in the Jupiter system and Jupiter itself. Under such circumstances, the first batch of clones finally landed on Ganymede. Looking at the vast land in front of them and feeling the extremely thin atmosphere, the clones were busy carrying out field survey tasks. While busy carrying out preliminary survey work in the Jupiter system, on the other side, after several months of sailing, the only aerospace mothership that had separated from the main fleet finally arrived at the end of this voyage. At this moment, it has entered the orbit of the planet and is rotating around this huge blue planet at a speed of about 10 kilometers per second. At this time, Li Qingsong temporarily stopped the preliminary preparations for the Jupiter system, and directly transferred his consciousness from a clone in the Jupiter system to a clone who was currently in orbit around this huge blue planet at the speed of light. The switch of consciousness took about 40 minutes to complete. The next moment, Li Qingsong opened his eyes and saw with his own eyes the planet where he had lived for decades, where he was born and grew up. Earth.
