When Europa approached Jupiter, some people put forward the "alien threat theory", believing that this phenomenon must be intentional by aliens, but no one believed it at all, and it didn't take long for this statement to be drowned in various hypotheses and speculations. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

However, as time passes, more and more evidence suggests that Europa is alien near Jupiter

Humans can study the situation on Europa, and there is no reason for aliens not to understand why the temperature of Europa is so high, and even if they really don't understand, a civilization that has gone to the universe will not be so difficult to study the truth.

Although aliens have far more space technology than humans, but so far, humans have not observed faster-than-light travel or similar super technology, and from all the signs that humans have mastered, it can be judged that Ganymede crossed the distant interstellar space in a conventional way, and finally reached the solar system, and no one knows how long this planet has been wandering in the universe.

However, even if Europa comes from Proxima Centauri, the long journey of four light-years is not so easy, at least a few thousand years to fly, and the probability that Callisto came from Proxima Centauri is very low.

There is also speculation in the astronomical community that the aliens' home galaxy may have had some kind of cosmic catastrophe and had to be forced to flee...... Similar episodes are not uncommon in human science fiction literature, and it is likely that the aliens first observed Earth, a habitable planet, before deciding to fly Ganymede to the solar system.

At that time, human beings on the earth were still in the Stone Age, and when he thought of the solar system, he found that the originally good primitive habitable planet was actually occupied by humans.

The aliens, who have long regarded the earth as a bag, naturally refused to give up, so they launched a brazen attack.

Of course, it may also be that Europa discovered the Earth when it flew near the solar system, and then temporarily decided to divert to the solar system and compete with humans for the Earth.

No matter what kind of guess you make, Europa will not fly in interstellar space for a short time, and a little physical common sense can guess some of Callisto's encounters.

The most important problem is the cold silence of interstellar space, which causes the heat of Europa to gradually dissipate, and the atmosphere gradually turns into ice on the surface of the planet; The inner workings of the planets slowly stopped, and even the Earth's core cooled and solidified.

According to the analysis, if it is only to restore the surface environment of Europa, there is no need for aliens to send Europa to a location as close to Jupiter. But on the flip side, if the aliens' intention is to restore Europto once and for all to re-melt the long-solidified core, then deliberately sending Callisto near Jupiter is easy to explain.

After all, Europa is the home planet of aliens, and if human beings have Yijia driving the earth to escape from the solar system and successfully reach a new galaxy, even if there is a habitable star with good conditions, it is impossible for human beings to completely abandon the home star of the earth, and the possibility of trying to restore the earth's environment is very high.

And what the aliens are doing is not to restore Europa's environment? It's just that the level of alien technology is higher than that of humans, so no one understands the aliens' intentions, and it is not until they observe the environmental changes on Europa that they discover the aliens' plans in hindsight.

In science fiction and film and television works, it is common for giant planets to have a habitable moon, and if everything goes according to the aliens' plans, then Jupiter will most likely have a habitable moon in the near future.

If the aliens didn't have the idea of attacking the earth, human beings might be able to live in peace with the aliens, but since the aliens sent the puffing virus to the earth, humans and aliens are destined to be endless rivals.

After reading the information sent by the earth, Huang Bo's whole person was not good.

Since the appearance of aliens in the solar system, they have not done anything earth-shattering, so that for a long time, the impression left by aliens on human beings is that it is plain, not like an interstellar civilization with a level of science and technology far beyond human beings, but like an ordinary civilization whose civilization level is similar to that of human beings, even if human beings have suffered heavy losses due to insect plagues, the impression of the vast majority of earthlings on aliens is still that "aliens are nothing great".

It wasn't until today that Huang Bo realized that aliens are not without means, but aliens use their means on the bright side, but few humans understand the mystery.

Now, everyone understands that the power of aliens has cast a shadow in everyone's hearts, and Huang Bo, who was full of confidence not long ago, suddenly had a bad premonition.

Isn't this just a matter of secrecy?

According to the request of the superiors, the contents of this document were quickly made public to all the crew members, causing an uproar among all the officers and men; although all the contents indicated in the document are only speculations at present, in light of the observations of the expeditionary fleet, and then reasonable analysis and reasoning, a conclusion similar to that of the document can be drawn.

For a time, pessimism permeated the expeditionary fleet, and everyone had a question in their hearts: Can we defeat the aliens?

With only a few days left before Jupiter, the top brass of the expeditionary fleet, who has always grasped the ideological dynamics of the officers and men, immediately launched an all-round ideological work in the fleet, and there is only one core of it -- even if the expeditionary warships are completely destroyed, they must let the aliens know that human beings are not easy to mess with!

Pessimistic or optimistic, the expeditionary fleet was ready to die at this time, and everyone was ready to sacrifice.

In the next few days, all the officers and men of the fleet were busy turning their backs on their horses, and several captains led their own staff groups to study the combat plan, imagine all the possible situations, and then look for countermeasures in a targeted manner.

The officers and men of the maintenance group not only overhauled and maintained all weapons and equipment, but also carried out a meticulous calibration of all naval guns.

The soldiers of the artillery crew not only maintained the cannons, but also checked all the shells in reserve and wiped them clean one by one.

The Marines wiped the power armor over and over again, wiped the rifle and the pistol, wiped the bullet with the pistol, and sharpened the saber.

Three days later, the second detachment of the expeditionary fleet composed of the Summer Bay and the Moon Bay was the first to enter Jupiter's magnetic sphere, and the wireless communication was unsurprisingly interfered with by the magnetic field, intermittent and noisy, and the problem was solved after switching to laser signals.

Two hours later, a detachment of the Hongwan and Luwan entered the magnetosphere.

After another twenty-seven hours, the second detachment cut into the orbit around Jupiter in reverse direction and began to orbit Jupiter, whose flight path was verified by several calculations, and did not approach any of Jupiter's moons during the operation, so as not to be intercepted by the alien fleet.

A few hours later, a detachment cut anterograde into the orbit around Jupiter and flew around Jupiter at a semi-major axis distance of 220,000 kilometers.

According to the battle plan, the two fleets continued to change their orbits to low orbits, and one detachment gradually approached the operating orbit of Europa.

The expeditionary fleet is spotted approaching, and alien spacecraft are spotted on Europa, Europa, Ganymede, and several other satellites, and a battle is about to break out.
