One Thousand Nine Hundred and Forty Six Breathe a Sigh of Relief

Although only Beiyuezhou responded in time, the changes on Jupiter soon spread throughout the world, and everyone's attention was focused on the alien planet not far from the earth.

Shortly after the Lone Wolf set off, the International Fleet organized all the warships left on Earth and headed for Europa as a matter of urgency.

Beijing and Washington held emergency consultations, and the two sides reached an agreement as quickly as possible to stop Europa at all costs!

This is a life-and-death battle. In the face of a crisis, both Beijing and Washington must put away their little thoughts and fight the crisis together.

Moreover, Io was too close, and countries could not block the news about Io. In less than half a day, the news had spread all over the world, and the people who were still immersed in joy were in an uproar.

The human fleet has driven away the aliens. Many people feel that the human fleet is powerful enough, but the aliens just start the planetary engine, leaving everyone helpless.

Humanity, which has gone through hardships, is far stronger than before the war, and the initial chaos was quickly brought under control. In addition to the space telescopes that monitor the alien fleet, all astronomical equipment in the world are aimed at Europa, even entry-level civilian telescopes. No exception!

From high-level officials to ordinary people, everyone is paying attention to the latest developments of Europa.

As the rotation speed of Io continued to decrease, the inclination angle of the planetary engine was also continuously adjusted. After four long days, when Io stopped rotating and the planetary engine was fully aligned, the light beam ejected from the water coincided with the The Earth's orbits are tangent to each other and are pointing towards the Earth!

When the Lone Wolf got the news, Ye Han, who had been worried for four days, laughed out loud on the spot. Others were also smiling and celebrating. The atmosphere on the bridge was a bit more lively than the Chinese New Year.

Ye Han sat in the command chair, feeling as if all the strength in his body had been drained.

On the surface, it only determines which direction the planetary engine is facing, but in fact, this small detail determines the safety of the earth!

At first glance, this statement not only makes no sense, but also seems quite alarmist. However, a few days ago, scholars in the astronomical community had already issued a warning: the orientation of the planetary engine will be directly related to the survival of the earth!

Most people don't know the reason, but as long as they have a little understanding of astronomy, they can figure out the reason. Whether the earth or other planets, they must have a certain speed in order to stably revolve around the Sun Park. This speed is fast. Or even if it's too slow.

If the speed is slow, there will not be enough centrifugal force.

The planet will be pulled towards the sun by the sun's gravity.

Although the distance between Io and the Earth is not far, once the speed of Io is too slow, the distance is enough for the gravity of the sun to pull Io out of the earth's orbit, and the impact will naturally cease to exist.

On the other hand, if the speed is faster, Io's orbit will expand outward, and it will also lose the chance of impact because it leaves the Earth's orbit.

Of course, if this is the case alone, humans don’t have to worry about Europa hitting the earth. The key is that Europa can use planetary engines to correct its direction. In this way, it is difficult to judge how Europa will act. This is the reason why everyone is always worried.

Okay now, the planetary engine is facing the earth, Europa must fly around the sun and catch up from behind before it can hit the earth. This process will take half a year at least, and it will not be able to catch up in three to five years at most. The fleet There's plenty of time to slowly build up Io.

Don't the aliens know that the risk of failure is higher? They must know, but since aliens do this, there must be some reason that humans don't know yet.

For example, the thrust of the planetary engine cannot resist the gravity of the sun, or the strength of Europa cannot withstand the two huge forces of the sun's gravity and the planetary engine.

All in all, there is no need to worry about Europa crashing into the earth for the time being. This is the result that everyone wants to see.

Ye Han still has a small extravagant hope in his heart. It would be better if Europa wanted to accelerate out of the earth's orbit, return to the outer reaches of the solar system, or even leave the solar system directly!

However, his idea soon came to nothing. Driven by the planetary engine, the stalled Europa kept accelerating along the Earth's orbit, apparently trying to hit the Earth from behind!

A few days later, the Lone Wolf flew to Io's original location, but Io had already flown far away, and the Lone Wolf could only continue to pursue it.

After a few more days, Io's speed finally stabilized. Beiyuezhou immediately recalculated the orbit data of Io. The results showed that Io will catch up with the Earth in one year and four months and take over Io. At such a speed, the impact would be enough to completely destroy both planets!

Ye Han really couldn't understand why the aliens were so crazy? Could it be that the purpose of aliens is to destroy the earth?

Little did he know that none of this would have happened originally, but in order to have absolute control of Io, the military set out to wipe out the resistance organizations on Io, making the aliens disguised as resistance organizations very dissatisfied.

Soon after, Chentang killed Kurakca again, and the only remaining alien royal bloodline was the single seedling on Europa Zero.

Aliens know deeply that today's human beings are no longer the weak planetary race they were in the past. Although humans have not been able to find the aliens hiding deep in Jupiter's moon for the time being, if the situation continues, it will only be a matter of time before they are discovered. thing.

After a period of hesitation and struggle, the aliens on Europa finally made up their mind to restart the planetary engine!

It is true that Io cannot return to interstellar space, but that is not because the planetary engine is faulty, but because the aliens do not have enough material reserves and the planetary engine is short of fuel. Let alone enter the vast interstellar space, even if it leaves the solar system, Can't do it.

If the aliens are given enough time, they can accumulate enough supplies, leave the solar system, and find another planet suitable for survival.

But are new planets so easy to find? Aliens have been wandering in the universe for so long, and the earth is the most suitable planet for survival in the entire journey!

Moreover, this war has been going on for so long. It is impossible for either side to let go of hatred, and it is impossible for humans to leave time for aliens to rise again. Let alone reserve excess supplies, the existing supplies are already very long if they are not consumed. Not bad.

Many aliens lamented that if they had chosen peaceful coexistence instead of war when they first arrived in the solar system, they would have already collected the necessary supplies and embarked on a new journey.

It's a pity that times have changed, and it is of no use to say these things now.

Various reasons, especially human military operations that seriously threatened the safety of aliens, prompted the aliens to make up their minds to impact the earth.
