The moon has a pivotal position in Chinese civilization, but the development of modern science has unveiled the veil of mystery, so that the gray cratered sphere in front of you really can't arouse too much interest. After only circling the moon twice, everyone became disgusted and began to prepare for the return voyage.

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

Looking at a semi-circular blue pearl inlaid in the dark sky in the distance, everyone sighed from the bottom of their hearts, it was so beautiful!

The plane slowly moved away from the gravitational pull of the moon, but kept the porthole on the Earth's side.

In fact, there are also people who want to take the opportunity to observe Jupiter and Saturn, but the portable telescope function is really not that powerful, and you can only barely see dim light spots.

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

In an instant, it attracted everyone's attention. The passion at the beginning has dissipated, and the same starry sky is really not as colorful as the earth. And now there is a comet, which of course makes everyone overjoyed.

In the distance, I saw a comet skimming the outer periphery of the Moon, and in the periphery of the Earth-Moon orbit, in the context of the universe, there was really no valid reference to estimate the size. But it doesn't matter, there are related functions on the plane.

In fact, when he saw the comet, he didn't need to be said by others, Mu Xinghai could decide for himself - to get closer to the comet.

To be honest, there are a lot of comets in the sky, but there are too few that can pass by just a short distance from the route.

Soon, in Didi's electronic voice, Long Xinsheng saw the approximate number of comets displayed on the screen next to him: the diameter of the comet nucleus is about 200 kilometers, the main material is rock and ice, and the density is initially estimated to be about 1.75g/cubic centimeter; The height of Huifa is 130 kilometers, and the length of the main body of the dust comet tail is 230,000 kilometers; The total length reaches 1.7 million kilometers; The length of the ion comet tail is 1.3 million kilometers. Now the speed is about 176,300 kilometers per hour.

The pilot's voice rang out again: "Ladies and gentlemen, please note that the Master Company has decided to send a Dream plane to chase the comet. Please vote on whether or not to chase the comet and get a close-up look at the elves of space. It is said that one of the heroes of the origin of life on Earth is the comet.

Please select yes or no.

However, going to observe the comet, there will be certain dangers. As of today, 17 moons have crashed due to the exploration of comets. Of course, these are all one-time satellites that crashed on their own initiative. ”

A dialog window will then automatically pop up with a green check mark and a red cross.

In an instant, the cabin began to be lively, and everyone started a lively discussion. Everyone wants to see the comet up close, but the danger makes some people hesitate. Everyone is worth a lot of money, how can you just take such a risk! What to do once you die!

Seeing that everyone was hesitant, Long Xinsheng stood and pulled out: "Everyone, don't forget that we spent 1.5 billion yuan." In addition, everyone knows how high the quality of the aircraft of the master company is, and since the pilots are not worried, we have nothing to worry about.

Since the master company took the initiative to separate the aircraft to explore, it shows that there is absolutely an almost perfect safety guarantee. It's not easy to come to space, are you willing to rub shoulders with a comet like this?

Also, I have a little bit of astronomical knowledge, which is not a lot of opportunities, maybe we only have such a chance once in our lives. Now that you're in the sky, why not give it a try! ”

Long Xinsheng's words touched everyone, in fact, everyone originally wanted to observe the comet up close, but one sentence was dangerous, but most of the people retreated. And now after Long Xinsheng's explanation, everyone has woken up, yes, the master company will definitely not let its employees take risks like this, nor will it use these planes that cost hundreds of billions of yuan to take risks. Unless, the master company wants to go bankrupt!

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

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

"Now the plane is traveling at 170,000 kilometers per hour and is 290,000 kilometers away from the comet. The plane is accelerating and is expected to approach in two hours. ”

The plane was speeding up at once, but all eyes were on the comet. Keep your eyes glued to the porthole and look at the magnificent comet in the distance. The comet in space is particularly beautiful, under the irradiation of the sun, the surface temperature reaches at least 120 degrees Celsius, under the low pressure of space, a large amount of water vapor gushes out, and the rainbow is close to the surface of the comet, like a dream.

And the long ionic comet tail changes blue, purple, crimson and other colors, like a magician of the universe.

Long Xinsheng excitedly set up the camera, trying his best to capture the scenes that could not be seen on this earth.

The plane maintained 3 times the gravitational acceleration, and a Dream plane in the distance had already moved forward with more than 30 times the acceleration, when the Feixiang spaceliner approached the tail of the comet, the Dream space shuttle piloted by Mu Xinghai had been on a par with the comet, or even faster, and had begun to prepare to take a ring photo around the comet. Every space exploration photo is precious. In order to take pictures of the comet, humans even took the initiative to command 17 satellites to crash on the comet, so that they could take thousands of pictures just before the crash.

"Passengers, please note that we are about to enter the comet tail range, don't panic if something goes wrong." The driver reminded him.

In general, there is nothing dangerous about comet tails, but it is not excluded in case. Generally, the main component of comet tail is extremely thin water mist ice crystals; But it is not excluded that there is gravel in it - this is fatal for the plane!

Now that the decision has been made to fly to the Comet, all the passengers are already excited to the extreme, and safety, all is left to the pilot.

"Oh...... We fly in the clouds of space! Suddenly, a passenger groaned in a dream-like voice, looking out the porthole at the body of the comet and the dense clouds.

"Unexpectedly, there are also volcanoes on the comet. It's just that it's all sprayed mist. Look, the column of water mist is hundreds of kilometers high, and it is difficult to see. The maximum height of volcanic eruptions on Earth is 56 kilometers, and here as far as the eye can see, there are dense white mist columns, none of which are less than 100 kilometers high. ”

"Oh yes! I photographed the sunrise of the comet! It's beautiful! It's like a crown! ”

On the plane, the bosses were once again excited, happily taking photos and even videos of themselves.

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