Half-immortal civilization

The moon plays an important role in Chinese civilization, but the development of modern science has lifted the veil of mystery of desire, so that this gray ball with pits and holes in front of us really does not attract much interest from everyone.After only circling the moon twice, everyone was disgusted and began to prepare to return.

But when you come to the moon, there is one thing you can't let go: that is to look at the earth on the moon.

Looking at a semicircular blue pearl inlaid in the dark sky in the distance, everyone sighed from the bottom of their hearts, it's so beautiful!

The plane slowly left the moon's gravitational pull, but it always aimed the porthole at the earth.

In fact, some people want to take the opportunity to observe Jupiter and Saturn, etc., but the portable telescope function is really not that powerful, and they can barely see dim spots.

"Comet! Comet! I saw a comet!" A person suddenly shouted.

In an instant, it attracted everyone's attention.The enthusiasm at the beginning has dissipated, and the starry sky is really not as colorful as the earth.Now that there is a comet, of course everyone is overjoyed.

From a distance, a comet can be seen skipping the outer periphery of the moon, at the outer periphery of the earth-moon orbit, and under the background of the universe, there is really no effective reference object to estimate its size.But it doesn't matter, there are related functions on the plane.

In fact, when he saw the comet, Mu Xinghai could make his own decision—to approach the comet without anyone telling him.

To be honest, there are really many comets in the sky, but there are too few of them that can pass by just not far from the route.

Soon, in the electronic sound of Didi, Long Xinsheng saw the approximate data of the comet displayed on the screen next to him: the diameter of the comet nucleus is about 200 kilometers, the main components are rock and ice, and the density is initially estimated at 1.75g About cubic centimeters; the coma has a height of 130 kilometers, and the main body of the dust comet tail is 23 kilometers long; the total length reaches 170 million kilometers; the ion comet tail is 130 million kilometers long.Now the speed is about 17.63 kilometers per hour.

The voice of the pilot sounded again: "Everyone, please note that the Master Company has decided to send a dream plane to chase the comet. Please vote whether to chase the comet or not, to observe a space elf at close range. It is said that One of the heroes of the origin of life is the comet.

Please choose yes or no below.

However, there will be certain dangers in going to observe comets.As of today, 17 human satellites have crashed because of exploring comets.Of course, these are all disposable satellites that crashed on their own initiative. "

Afterwards, a dialog window automatically popped up on the screen, displaying a green checkmark and a red cross.

In an instant, the cabin became lively, and everyone had a lively discussion.Everyone wants to observe the comet up close, but the sentence is dangerous, which makes some people hesitate.Everyone has a huge net worth, how can they take risks like this!What to do once you die!

Seeing that everyone was still undecided, Long Xinsheng stood up and said, "Everyone, don't forget that we spent 15 billion yuan. In addition, everyone knows the quality of the aircraft of the expert company. Since the pilots are not worried , we have nothing to worry about.

Since the master company took the initiative to separate the plane to explore, it means that there is absolutely almost perfect safety guarantee.It's not easy to come to space, are you willing to pass by a comet like this!
Moreover, I also have a little knowledge of astronomy. There are not many such opportunities. Maybe we only have such an opportunity once in a lifetime.Now that it's in the sky, why not give it a try! "

Long Xinsheng's words moved everyone. In fact, everyone wanted to observe the comet at close range, but the word "dangerous" made most of them retreat.But now after Long Xinsheng's explanation, everyone has come to their senses, yes, Master Company will definitely not let its employees take risks like this, nor will they take risks with these planes that cost hundreds of billions of dollars.Unless, Master Company wants to go bankrupt!

Soon, all 16 people chose yes.This means that even if an accident occurs, the master company will only need to bear a very small cost.

"Now the plane is starting to accelerate, please remember your seat belt." The voices switched to a gentle female voice together.

"The speed of the plane is now 17 kilometers per hour, and the distance from the comet is 29 kilometers. The plane is accelerating and is expected to approach in two hours."

The plane was accelerating, but all the people set their sights on the comet.Press your eyes tightly on the porthole, watching the magnificent comet in the distance.Comets in space are extraordinarily beautiful. Under the sunlight, the surface temperature reaches at least 120 degrees Celsius. Under the low-pressure space, a large amount of water vapor gushes out, and rainbows cling to the surface of the comet, like a dream. magical.

And the long ion comet tail changes colors such as blue, purple, and deep red, like a magician of the universe.

Long Xinsheng excitedly set up the camera, and tried his best to capture the scene that could never be seen on the earth.

The aircraft has maintained 3 times the acceleration of gravity, while a dream aircraft in the distance has already advanced with an acceleration of more than 30 times. When the space shuttle Feixiang approached the comet's tail, the space shuttle Dream piloted by Mu Xinghai was already on par with the comet , and even faster, have already started preparing to take pictures in a ring around the comet.Every space exploration photo is precious.In order to take pictures of the comet, humans even took the initiative to direct 17 satellites to crash on the comet, just to take thousands of pictures before the crash.

"Passengers, please pay attention, we are about to enter the range of the comet tail, don't panic if there is a problem." The driver reminded.

Generally speaking, comet tails are not dangerous, but the possibility cannot be ruled out.Generally, the main component of a comet tail is extremely thin water mist ice crystals; but it cannot be ruled out that there are gravel in it-this is fatal to the aircraft!

Now that they have decided to fly to the comet, all the passengers are already extremely excited, and all safety is left to the pilot.

"Oh...we are flying in the clouds and mist of the universe!" Suddenly a passenger groaned in a sleepy voice, looking at the main body of the comet and the dense clouds and mist that were close at hand outside the porthole.

"Unexpectedly, there are also volcanoes on comets. It's just that they are all jets of water mist. Look, the water mist column is as high as hundreds of kilometers, which is difficult to see. The maximum height of a volcanic eruption on the earth is 56 kilometers, and here it is all a piece of water as far as the eye can see. There are dense white water mist columns, none of which is less than a hundred kilometers high."

"Oh yeah! I caught the comet sunrise! So beautiful! It's like a crown!"

On the plane, the bosses regained their excitement once again, happily taking photos and even videos of themselves.

But Mu Xinghai, who has circled the comet several times and collected all the data and pictures, is preparing for the next move!
