The moon plays an important role in Chinese civilization. However, the development of modern science has unveiled the mystery of desire, so that the gray bumpy sphere in front of us really does not arouse much interest. After only two circles around the moon, everyone was disgusted and began to prepare to return.
But when you come to the moon, there is one thing you cannot miss: looking at the earth from the moon.
Looking at a semicircle of blue pearls embedded 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 gravity, but always pointed its porthole toward the earth.
In fact, some people want to take the opportunity to observe Jupiter and Saturn, but the function of the portable telescope is really not that powerful, and they can only barely see dim spots.
"Comet! Comet! I saw a comet!" A person suddenly shouted.
In an instant, it attracted everyone's attention. The initial excitement has dissipated, and the same starry sky really lacks the splendor of the earth. And now there is a comet, which of course makes everyone overjoyed.
From a distance, I saw a comet passing the periphery of the moon. It was on the periphery of the earth-moon orbit. In the context of the universe, there was really no effective reference to estimate its size. But it doesn’t matter, there are related functions on the plane.
In fact, after seeing the comet, Mu Xinghai could decide by himself without anyone else's advice - to approach the comet.
To be honest, there are a lot of comets in the sky, but there are too few that can pass by not far from the flight path.
Soon, amid 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's nucleus is about 200 kilometers, the main components are rocks and ice, and the density is initially estimated to be 1.75g. About cubic centimeters; the coma height is 130 kilometers, the main body length 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. The current speed is about 176,300 kilometers per hour.
The pilot's voice sounded again: "Everyone, please note that the Master Company has decided to send a Dream aircraft to chase the comet. Please vote on whether to chase the comet and observe this elf in space up close. It is said that on earth, One of the heroes of the origin of life is comets
Please select yes or no below.
However, there will be certain dangers in going to observe comets. As of today, 17 human satellites have crashed due to exploration of comets. Of course these are all disposable satellites that crashed on their own initiative. ”
Then, a dialogue window automatically popped up on the screen, showing a green check mark and a red cross.
In an instant, the cabin became lively and everyone started a lively discussion. Everyone wants to observe the comet up close, but the word "dangerous" makes some people hesitate. Everyone is rich, how can we take risks like this? What to do if you die!
Seeing everyone's hesitation, Long Xinsheng stood up and said: "Everyone, don't forget that we spent 1.5 billion yuan. In addition, everyone knows the quality of Gaoshou Company's aircraft. Since the pilots are not worried , we have nothing to worry about.
Since the expert company has taken the initiative to separate aircraft for exploration, it means that there is absolutely almost perfect safety guarantee. It’s not easy to go 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 opportunities like this. Maybe we only have this opportunity once in our lifetime. Now that you've arrived in the sky, why not give it a try! ”
Long Xinsheng's words moved everyone. In fact, everyone originally wanted to observe the comet up close, but the words "dangerous" made most of them retreat. But now after Long Xinsheng's explanation, everyone has woken up. Yes, Gaoshou Company will definitely not let its employees take risks like this, nor will it take risks with these aircraft costing hundreds of billions of yuan. Unless the master company wants to go bankrupt!
Soon, all 16 people chose yes. This means that even if an accident occurs, the expert company will only have to bear minimal costs.
"Now the plane is accelerating, please remember to fasten your seat belts." The voices switched to a gentle female voice.
"The current speed of the plane is 170,000 kilometers per hour, and the distance from the comet is 290,000 kilometers. The plane is accelerating and is expected to approach in two hours."
The plane was accelerating, but everyone's eyes were fixed on the comet. Close your eyes to the porthole and look at the magnificent comet in the distance. Comets in space are 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 spurts out, and rainbows cling tightly to the surface of the comet, like a dream. magical.
The long ion comet tail changes colors such as blue, purple, crimson, etc., like a magician of the universe.
Long Xinsheng excitedly set up the camera, trying hard to capture a scene that could not be seen on earth.
The aircraft maintained 3 times the acceleration due to gravity, while the Dream aircraft in the distance was already moving forward with an acceleration of more than 30 times. When the Flying Spaceliner was approaching the tail of the comet, the Dream Space Shuttle piloted by Mu Xinghai was already keeping pace with the comet. , even faster, has begun preparing to take pictures in a circle around the comet. Every space exploration photo is precious. In order to take photos of comets, humans even took the initiative to direct 17 satellites to crash on comets, just to take thousands of pictures before crashing.
"Dear passengers, please note that we are about to enter the comet's tail range. Don't panic if there is a problem." The driver reminded.
Generally speaking, there is no danger in the comet tail, but the eventuality 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 gravels in it - this is fatal to aircraft!
Now that they have decided to fly to the comet, all the passengers are extremely excited, and safety is left to the pilot.
"Oh... we are flying in the clouds and mist of the universe!" Suddenly a passenger muttered in a dreamy voice, looking at the main body of the comet and the dense clouds and mist just outside the port window.
"I didn't expect that there are volcanoes on comets. They are just sprays of water mist. Look, the water mist columns are hundreds of kilometers high, which is hard to see. The maximum height of volcanic eruptions on the earth is 56 kilometers, and here you can see that they are all a There are densely packed white water mist pillars, none of which are less than a hundred kilometers high.”
"Oh yeah! I caught the sunrise of the comet! So beautiful! It looks like a crown!"
On the plane, the bosses once again regained their excitement and happily took 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!
