Urban Inventor

In fact, the moment Zhang Wei, Liu Hai, Qin Xiaobu, and Zhang Zhijian arrived on the moon, their goal had already been achieved, and now they can return to the earth, but it is rare to travel to the moon. Life.

The first experience project must be to see the earth from the moon.

Zhang Wei is on the surface of the moon facing the earth at this time. Looking at the earth from here, what he sees is a bright blue pearl inlaid in the dark sky, which is beautiful and shocking. In addition, on the moon The earth seen from the sky is also very large, even more than ten times larger than the sun.

In addition, observing the universe from the moon is also a fresh experience. Even though it is daytime on the moon, the sky of the moon is still black. In the sky, apart from the spectacular earth, there are also stars in the sky, but these stars are not Flickering, this is not because the stars have become obedient, but for another reason: "When you look at the stars on the earth, you will feel flickering, because the atmosphere around the earth is uneven and moving, causing light to refract and change. This is the principle of shaking when looking at the scenery above the asphalt road, and there is no atmosphere on the moon, so naturally there will be no flickering effect."

After seeing the earth and the stars, Zhang Wei is ready to take a round-the-world trip on the moon. He has already made relevant preparations and transported a flying car to the moon.

"Set off!"

Zhang Wei, Liu Hai, Qin Xiaobu, and Zhang Zhijian boarded the flying car and started traveling around the moon, and the live broadcast screen also switched to their perspective. More than one billion viewers will travel around the moon with them. It was arranged, and the relevant equipment was technically transformed to ensure that there is a signal during the live broadcast.

The audience was hooked.

"The biggest anchor in history has been born!"

"The live broadcast of traveling around the moon is definitely the most exciting live broadcast in history, I can't accept it!"

"Guanghan Palace, I want to see Guanghan Palace, Fairy Chang'e and Jade Rabbit."

"It is impossible for Chang'e to have drops, but it is possible to encounter aliens. Dr. Zhang, you have to take it easy and run away if you encounter aliens. Otherwise, if you are captured by aliens for breeding, we humans on earth Lost the greatest genius of all time."

"There are really aliens on the moon. It is said that when the United States landed on the moon in 1969, the TV signal was suddenly interrupted for a few minutes because Armstrong met the aliens on the moon. The aliens also warned the earth people to leave the moon, and those Aliens have high-tech technology beyond the reach of human beings, and they only need an hour at most to destroy the earth. And the United States has not dared to go to the moon for so many years because it is afraid of aliens on the moon.”

"Nimei's alien,

You write science fiction, right? "

While the audience was discussing, Zhang Wei had already set off in the flying car, quickly shuttled across the desolate moon.

There is no fairy Chang'e, no goddess of the moon, no animals, no plants, no buildings, and no aliens, only craters that can be seen everywhere... The moon shown in the live broadcast is just a desolate and dead world.

The audience couldn't help being a little disappointed, looking forward to seeing something a little more exciting. At this time, Zhang Wei drove the flying car to the mysterious back of the moon.

People have always been full of curiosity about the back of the moon, because people always see the front of the moon and have never seen the back of the moon. Many people suspect that the back of the moon is actually the habitat of aliens. However, this is actually because the moon's rotation period is exactly equal to its revolution period around the earth, so it can only always face the earth with the same side. This phenomenon is relatively common in planetary and satellite systems. You can do an experiment: hang an electric light in the house, and you rotate around the light while "revolving". When the periods of the two are equal, then the electric light can only illuminate one side of you forever.

I turned around on the back of the moon and found nothing. Not only the audience was disappointed, but Zhang Wei’s interest in traveling also gradually faded. This corner of the moon is not a good place to travel at all. I guess most people If you have been here once, you will not want to come again, unless humans have already started to modify the moon and immigrated to the moon.

After continuing to sway on the moon for a while, Zhang Wei drove the flying car back to the "Future" spacecraft, ready to return.

Only he, Liu Hai, Qin Xiaobu, and Zhang Zhijian were the only ones who returned, and the other 16 astronauts stayed on the moon to continue working. They had enough materials and equipment to build a small base for them to rest. Even on the moon, they can live the same as on the earth. In addition, they also carry a large amount of food, water, oxygen and other materials, enough to survive for three months. It will take no more than two days to set off to the moon at the latest.

"Beidou, start returning."

After Zhang Wei entered the spaceship, he rested for a while, and then gave instructions.

The voice of Beidou sounded immediately, "Everyone, please pay attention, the spaceship has started to return, and there are still ten seconds to officially take off, ten...nine..."

Ten seconds later, the anti-gravity device was activated, the ion engine was activated, and the "Future" spacecraft lifted off vertically and left the lunar surface.

At this time, Liu Hai suddenly shouted excitedly, "Comet, I saw a comet, and the comet is flying in the direction of the moon."

Hearing the words, Zhang Wei came to the window, picked up the binoculars curiously and looked over, and sure enough, he saw a comet. He was immediately overjoyed. Compared with the desolate and dead moon, the gorgeous comet dragging its long tail across the sky was more arousing to him. interest of.

What surprised him even more was that the comet was very close to the moon and was flying towards the moon, so it seemed that he could observe it at a close distance.

Zhang Wei immediately ordered, "Beidou, calculate how long it will take us to get close to this comet?"

"In the calculation... the comet's nucleus is about seven kilometers in diameter, about 230,000 kilometers away from the moon, and the speed is about 113 kilometers per second... If we approach the comet at full speed... it is expected to meet the comet in two hours and thirty minutes. "

Beidou responded.

"Change the destination, don't go back to Earth, and go to meet this comet for a while."

Zhang Wei said, looking a little excited.

"Dawei, although it is said that with the capabilities of the 'Future' spacecraft, it is not dangerous to observe comets at close range, but it is not necessary, after all, even if we can't go there, we can use astronomical telescopes to observe comets perfectly. "

Qin Xiaobu said.

"Observing the comet at close range is only one of the purposes. I also want to destroy the comet with an electromagnetic railgun and show everyone the power of our future technology company."

Zhang Wei said, "When we mine lunar resources, especially a large amount of helium-3, ilmenite and other resources, the competition in space will be unprecedentedly fierce, and other countries will definitely be jealous, and will hate our company more and more. A look at the strength can give everyone a shock. And I have an agreement with the country that our company can develop private armed forces in space, so starting from landing on the moon, our company's military force no longer needs to be hidden, it can be appropriate This is part of the show, and now it is our first show of force, and of course it has to be a bit of a sensation."

Liu Hai also nodded when he heard the words, "That's true, and the comet's nucleus is only seven kilometers in diameter. With the powerful electromagnetic railgun, it can be completely destroyed." (To be continued.) ()
