Half-immortal civilization

(Incorrect data in the previous chapter, the orbital radius of Jupiter is 7.78 million kilometers. The outermost orbital radius of the asteroid belt is regarded as that of Jupiter. The data records are too messy ⊙﹏⊙)

As the fleet approached, an unprecedented world appeared in front of everyone.

The beautiful magic ball turned into a violent ocean. A storm with a speed of 400 kilometers per hour swept across the entire surface of the planet. Thick red, yellow, and white clouds were constantly tearing and gathering on the surface.And there is a layer of hazy atmosphere on the surface of Jupiter—in fact, the Jupiter we see is the cloud layer on the surface of Jupiter. We calculate the diameter of Jupiter from one atmospheric pressure.In fact, Jupiter's overall diameter is much larger.It's just that this is a liquid planet (should be a gas planet, but Baidu has been using it for a long time. The scientific saying is that it is a liquid planet. It may be that the interior is more liquid due to atmospheric pressure), and there is no real surface.

And as they approached, they also saw a mysterious and beautiful halo, and the mystery faded away. Some of them were just large and small fragments, and the small ones could hardly be seen clearly, and the big ones were no bigger than a passenger car.Compared with Saturn, Jupiter's halo is much weaker, and it is not possible to see some debris falling into the interior of Jupiter. Obviously, this beautiful halo is constantly disappearing.

"This is Li Canglan, the fleet of Master Company. We are entering Jupiter's magnetic field. Everyone should turn on the magnetic field generating device to protect themselves. Also, please pay attention to the time. We must always be under the protection of the magnetic field generating device, that is to say, we must always turn on the magnetic field generating device Device. The power of the new special magnetic field generating device is 800 million degrees per hour, and the minimum power stored in our spacecraft is only 3 million degrees. Excluding the energy required for flight, etc., it can only work for one day, no more than 30 hours.

But if the spacecraft are clustered together, the magnetic field can be turned on in turn.Therefore, please do a good job of coordination within the group.The duration of this visit is expected to be one week.If the energy is exhausted ahead of time, the spacecraft can only be abandoned. "

The collision between the magnetic field and the magnetic field cannot be seen.But what if you add some charged particles?That is the most beautiful brilliance, the aurora, which is familiar to everyone.Of course, Jupiter also has strong radiation, especially its north pole has a hexagonal radiation magnetic field.its radiation intensity.Comparable to the surface of the sun.Some people say that Jupiter is a planet that failed to compete with the sun for resources.

With the artificial magnetic field turned on, dots of fantastic colors appear in space.All flying machines come together.Only the Explorer spacecraft of the Master Company has the magnetic field turned on.Look from a distance.A colorful sphere with a distance of about tens of thousands of kilometers.It appeared in space, leaving a long tail behind it, gradually fading away.Finally disappeared into the void.

Soon, the spacecraft team came near Jupiter, and then divided into four groups, each group flew to a satellite.Although Jupiter has many satellites, the four satellites of Io [-] are particularly large. The smallest ones are similar in size to the moon, and the largest diameter is a quarter larger than that of the moon.And this time, the goal of the master company is also these four satellites.

Among them, the second group of spacecraft formations docked steadily over Europa Europa and between Jupiter and Jupiter. There are about 70 spacecraft, and there are 12 adventure groups in total.Among them, five spaceships turn on the magnetic field generators and join together to firmly block the magnetic field of Jupiter, and support a magnetic field vacuum space for Europa, which has about a quarter of the surface area.

"Hurry up and get ready. The master company's space shuttle will arrive in 30 minutes, and we will head to Europa!" Mo Yun shouted excitedly.

Landing on Europa is exciting just thinking about it.After a week or so of traveling in outer space orbiting Mars, everyone has gradually adapted to the state where life activities slow down.In fact, this is not difficult to understand. After all, these people often go to small belts to hunt wild food, and have gradually adapted to the environment of the universe.

Everyone is busy putting on their space suits.The expedition team is divided into two groups, one for rest and one for work, each working for 12 hours, with a one-hour handover time in between.Such an arrangement is actually very tight; but the cost of space exploration is too high, and master companies have to make such arrangements.In order to train astronauts, these expenses are actually paid by expert companies in the end, and these space explorers must also be provided with rich remuneration.

"On February 2068, 2, New Year's Eve, at 2 o'clock in the morning, we set off." Mo Yun gently closed his notebook, put it back in his package, and resolutely turned his head and walked out of the spaceship, entering the space where the master company had come. space shuttle.There are more than 1 people in the monster adventure team. This time, 300 people were dispatched. Three of the newly modified Feixiang series space shuttles were used.

Close observation reveals that Europa is indeed an ice ball, but after strict calculations, it still has a metallic core and a rocky mantle.On the contrary, the outer Ganymede and IV have a higher water content, as high as 50%.However, Europa is a bit special. Almost all the water (ice) is on the surface, forming an ice layer about 100 kilometers thick.The water content on it is almost the same as the water on the earth!Ganymede and Ganymede are more like a frozen aggregate, dust and ice are mixed together, and the entire planet is permafrost, with only a small amount of water and ice gathered together.

Europa has a thin atmosphere above it, much weaker than that of Mars.Its pressure is less than one-thousandth of that on Earth.But what is amazing about it is that [-]% of it is oxygen! ! !In other words, if the pressure and temperature are right enough, you can breathe directly without wearing a spacesuit.

The air above Europa is a spectacle formed by the combined effects of radiation and gravity.Radiation and magnetic fields cause the water molecules to split, and then, under the action of gravity and ionic winds, the heavier oxygen atoms remain and the hydrogen atoms are blown away.Over time, this spectacle has been formed.

In fact, the mechanism of action here is the same as that on Venus.It's just that Venus received too much radiation, and the decomposed oxygen atoms and hydrogen atoms were blown away; the heavier carbon dioxide remained.Finally, the wonderful planet Venus was formed.

"Hi everyone, I'm Hong Dali, are you ready?" the driver of the master company in front asked "slowly".Leaving the orbit of Mars, everyone's life activities are miraculously full, but I can't feel it.

"Seat belt No. 1 is fastened." "No. 2 is over." No. 3...

Pilot Hong Dali: "Take off from now on, the countdown is 10, 9..."

The plane accelerated slowly.If you want to log on to the planet, you must use an airplane, because - it has wheels!Spaceships have no wheels, and when they reach the planet, they just crash.Only by slowing down through wheel taxiing can you land safely and accelerate takeoff with ease.

"Emergency notice." A huge voice suddenly sounded, it was Li Canglan's voice. "There is a thin layer of pure oxygen on Europa, and it is affected by radiation. It has a large number of extremely active free oxygen ions, which have a huge corrosive effect. Please open the parachute and slow down the speed as much as possible when the plane lands. Accident."

"Got it!" The driver replied calmly.As an elite of the master company, even in the face of life-threatening, they can keep calm.Because of panic, it will only let the last trace of life slip away...

The escape velocity of Europa is only 1.3 kilometers, which is about 1000 meters smaller than that of the moon.The plane must be slow, otherwise even if it lands, it will rush out of the planet.But for the master company's space shuttle, the speed of 1000 meters per second is really not big.

The frozen world shows a little blue - the light is too dark, there are also reasons such as the reflection and transparency of the ice.This kind of color gives people a particularly cold psychological reaction.

Three huge flying series space shuttles with a length of more than 30 meters landed slowly.However... this planet is not friendly!Just as the plane was about to land...

With a bang, the detected landing site collapsed out of thin air, and a crack with a width of one kilometer suddenly appeared. A large number of ice subsidences, scattered ice crystals, water droplets, and a large amount of water vapor suddenly shot up into the sky...

Most importantly, by an extremely coincidental coincidence, the location where the crack appeared happened to be the landing point of the plane... (to be continued...)
