Jupiter is called "Jupiter" by Westerners, and "Tai Sui" and "Tai Sui" in ancient China. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 infoThe largest and fastest rotating planet among the eight planets in the solar system, its mass is one-thousandth that of the Sun and 2.5 times the mass of the other seven planets in the solar system combined.

Jupiter is a gas giant with no physical surface, and its main components are hydrogen and helium, which account for 90% and 10% respectively, and the density of gaseous matter increases with depth, and the central temperature is expected to reach as high as 30,500 °C.

It was the first time Zhou Chen had observed Jupiter so closely.

Big! Very big!

He couldn't put into words the sheer size of Jupiter, and the immediate visual impact left him speechless for a long time.

1,316 times the volume of the Earth and 318 times the mass of the Earth, when he was next to Ganymede, the Jupiter he saw occupied almost the entire field of vision, and the shock seemed as if his heart was trembling.

Jupiter's surface is divided into a number of different colored bands according to different latitudes, and from time to time there are turbulent currents and storms, the most famous example is the Great Red Spot, even a random turbulence can overturn the entire earth, which is the most intuitive embodiment of the vastness of the universe.

"Commander, are we landing on Ganymede now?"

Just as Zhou Chen was still in the shock brought to him by Jupiter, Dandan's voice suddenly sounded.

Zhou Chen came back to his senses, looked at the speckled planet not far away, and nodded subconsciously.

In the next second, he felt that the "Blue Qiong" adjusted its flight attitude and quickly leaned towards Ganymede.

Ganymede, also known as Ganymede, is a moon that orbits Jupiter. Sorted by distance from Jupiter from near to far, it ranks seventh among all Jupiter's moons.

Although Ganymede is only a moon of Jupiter in terms of status, it is a very unique moon.

The first is its size, with an average radius of 2,600 kilometers, Calmede is a little larger than Mercury and about half the mass of Mercury, making it the largest moon in the solar system. Second, Europa is composed mainly of silicate rocks and ice, with star-layered stars and an iron-rich, fluid core.

That is, it possesses a magnetic field! It is the only known moon in the solar system that has a magnetosphere.

In March 2015, NASA announced the discovery of a giant saltwater ocean under the Ganymede Ice Sheet, with liquid water levels exceeding those of Earth! In addition to the presence of water, high-resolution NIR and UV spectroscopy results show the presence of other substances, including carbon dioxide, sulfur dioxide, and possibly cyanide, bisulfate, and a variety of organic compounds.

In addition, it possesses a thin oxygenated atmosphere containing atomic oxygen, oxygen, and ozone.

Whether or not Ganymede has an ionosphere has not yet been determined.

All kinds of signs showed that Europa was extraordinary, so when the earthly fleet approached the surface of Ganymede, Zhou Chen's heart was full of anticipation.

Is there a possibility of life on Ganymede, and if so, it is really a major discovery, which means that Ganymede may be another planet with life besides Earth.

However, the actual situation disappointed Zhou Chen.

As the Blue Qiong slowly descended to the surface of the satellite, what came into view was a white expanse, and Europa was actually a huge ice cave, full of cracks, ramparts, and trenches. In this extremely cold environment, any life activity will go into a dormant state.

Disillusioned, Zhou Chen ordered the "Blue Qiong" to fly around Ganymede, but except for seeing the remnants of the impact crater like a ring of hearts, he didn't even find a special place.

"Forget it, maybe human expectations for it are too high."

As the saying goes, the greater the hope, the greater the disappointment, and Zhou Chen, who had found nothing, finally had to order the "Blue Qiong" to return home, so that the entire Earth fleet could find a suitable place to camp near Europa.

With the replenishment of the resources of the "Metal Planet", the maintenance progress of the Earth Fleet has obviously accelerated a lot, Zhou Chen just took a nap in the captain's lounge, and when he woke up, he found that the entire fleet had once again entered a tense and busy state.

Refining metal is refining metal, manufacturing equipment is manufacturing equipment, and a special engineering robot for maintenance is constantly being manufactured from the production line, and then after charging, it is also engaged in the hot work.

Outside the portholes, countless robots and drones are shuttling, and makeshift camps are expanding at a rate visible to the naked eye. On the other side, the repair of several giant ships is also in full swing.

Of course, correspondingly, the materials from the "metal planet" are also rapidly consumed.

There is no way to go on like this, Zhou Chen hurriedly called Dandan, and asked it to quickly start collecting resources.

Fortunately, this is the periphery of Jupiter, and it is no longer a barren moon. Not only are there abundant asteroids nearby, but even Jupiter has become its pool of natural raw materials!

At present, the energy used by the Earth fleet is mainly nuclear fusion energy, and the energy required for nuclear fusion is precisely the most abundant hydrogen and helium reserves of Jupiter, and after a fusion, new elements are obtained, which can still be used for fusion reactions.

With the current "throughput" capacity of the Earth Fleet's power system, it is enough to ensure that all the matter before the emergence of iron is used as fusion energy source.

In other words, the power heart of the Earth fleet can continuously inhale low-atomic materials such as hydrogen and helium, and spit out iron.

During this period, not only the energy supply was ensured, but also the metal iron needed by the fleet was also supplied!

These metallic irons are then smelted and mixed with other substances naturally occurring in the universe to produce a variety of high-performance alloy materials!

Its ultra-high utilization rate simply made Zhou Chen's hairs from the earth stand on end.

Because as long as the atomic weight is smaller than iron, all of them can be thrown into the "boiler" as raw materials, which is the real "eating people without spitting bones"!

Of course, with such an efficient utilization rate, Zhou Chen's confidence has also been greatly boosted.

This means that he is getting closer to his next goal.

If there is anything that Zhou Chen is most dissatisfied with now, it is undoubtedly the composition of the Earth Fleet. To put it mildly, although the current Earth Fleet is a creation born from the Odo civilization, a third-level civilization in the universe, in fact, its essence is just a logistics supply ship.

No matter how huge the "Blue Qiong", "Meteorite", and "Poseidon" are, they can't change their essence as "second-line warships"!

When the current Earth Fleet is truly repaired, Zhou Chen's next plan will be put on his daily basis, that is, to build a real fleet that can be used for battle!

In the reference opinions provided by Dandan, the real key to the strength of a fleet is the ability of the combat ships, and the construction level of the ships with the strongest combat power in a fleet is generally used as a standard to measure the level of the fleet.

The safety of a fleet can be guaranteed only if the strength of the combat ships increases.

According to the universal standards in the universe, a powerful third-level civilization fleet generally has at least one or more warships that meet the "continent-class" standard.

Its indicators include several points: first, the main battleship has a high-energy shield, which can defend against general particle attacks; Second, it has the ability to attack in a wide area, which can seriously damage the enemy from a considerable distance; Third, the speed of travel reaches the minimum speed of 0.8 times the speed of light, and it has the ability to travel between stars, and fourth, the energy drive reaches the level of antimatter engines.

As far as the current Earth fleet is concerned, the first and third points can be barely achieved when the fleet repair is completed, thanks to the heritage of the Odo civilization.

What is lacking is the very important second and fourth points, wide area attack capabilities and antimatter engine drives.
