Warship of Great Power

Carlos is literate. He must let everyone know that he is on the moon and is not faking it. There are many ways to test it, and the measurement of gravity acceleration is one of them.

On the earth, the value of gravitational acceleration is 9.8. For approximate calculation, it is 10. According to the formula H=g*t*t/2, it can be calculated that on the earth, one second can cause a drop of five meters. , and on the moon, the acceleration of gravity is only one-sixth that of the earth, so the height of fall in one second is less than one meter.

Carlos raised his hands flat, about 1.6 meters above the ground, then released his hands, and the pencil fell freely. There was no need to calculate the time. The time label on the video just fell past his in one second. Thigh part.

"This is not a slow play, this is a live broadcast. Everyone should be able to know how small the gravity is here. When we get out, we can have fun on the moon, so that we can better understand how strong the gravity is on the moon." Carlos bent down and picked up the pencil: "Of course, before that, we need to fill our stomachs first. For this meal, I want to change the flavor, Kung Pao Chicken."

Carlos fell in love with oriental food. In order of order, the first dish is fish-flavored shredded pork, and the second dish is kung pao chicken, which tastes great too.

At this time, Carlos opened the bag of Kung Pao chicken, poured it into the plate in front of him, and stuffed the napkin to his chest. Even though he was eating on the moon, it still had to be ritualistic.

After all, he also has to live broadcast his meals. If he is in space and has a weightless environment, he cannot pay attention to it. On the moon, he can eat the same as on the earth. He enjoys this feeling very much.

Countless people watched Carlos' actions on the TV, watching him eat Chinese food elegantly with a knife and fork. It felt funny, especially when Carlos used a fork to insert peanuts, and the peanuts swished. With a click, he flew out!

"As long as you go to heaven, there is an unwritten rule. Whoever soils the environment must be responsible for wiping it. Others will not care. Therefore, when eating in the lunar module, you must be careful not to soil it. environment."

Carlos ignored the peanut that he had inserted into the air and continued to eat another one. Fortunately, he learned the lesson this time and directly inserted the peanut horizontally with a fork, then put it in his mouth and chewed it. : "Not bad, the taste is very good. I recommend that you go to the East to eat Chinese food. The Chinese food eaten in the West has been changed, especially the butter. It is very unpalatable."

Carlos continued to eat leisurely until Pan Chun couldn't help it anymore: "Mr. Carlos, we only have fifteen minutes to eat. After all, we will need a lot of time to put on and take off the space suits."

This also takes time, how much specifically?

At that time, the spacesuit designed and manufactured by Americans took 45 minutes to put on and the same time to take off. It also required help from outsiders, such as taking off pants. In a weightless environment, you could not take them off yourself. You needed help. There were helpers outside, holding the astronaut's arms and pushing on the metal device on the waistband of his pants. It would take a lot of effort to help him take off his pants.

Therefore, when Dongfang was developing its space suit, it followed Lao Maozi's route: an integrated rear door opening, or back put-on/take-off structure. It is much easier to enter the space suit through a special hinged door on the back. .

Dongfang's spacesuit only takes a few minutes to put on, but this is for professional personnel. For people like Carlos, it will definitely take a long time to put on and take off.

If you take a long time to eat first and a long time to get dressed, then you won't be able to get out?

"Okay, I'll eat quickly." Carlos looked at the camera: "You don't need elegance on the moon, you need efficiency." After saying that, Carlos started to eat, and soon he had the full plate of rice in his mouth. "

Since he had put plastic wrap in advance, he didn't have to wash the dishes. In fact, there was no extra water for him to wash the dishes. He cleaned up and took out a garbage bag.

"We must pay attention to environmental protection and cannot throw away garbage casually, so when we go out later, we will dig a pit when collecting lunar soil. At that time, I will bury the garbage in it."

After dinner, quickly put on your spacesuit!

Carlos blinked at the camera: "Dear viewers, I want to disappear for a while, because the next scene is not suitable for children, and I need to put on diapers first."

Many daily necessities were invented by scientists to solve special problems. Diapers are one of them. They were prepared for astronauts. In the early days, they could not relieve themselves in the spacecraft. Later, they could not perform these daily operations during extravehicular activities. , then there must be something particularly absorbent, so diapers were invented.

It is not easy to do an extravehicular activity. If there is a need, solve it directly. You cannot go back and solve it before coming out.

So, inside is the diaper, and then the liquid cooling suit.

Isn't space very cold? Why do you still need a liquid cooling suit?

Space is cold, but the space suit has isolated the coldness of outer space. There is a special vacuum insulation layer on the outside of the space suit. No matter whether it is cold or hot outside, it has nothing to do with the inside. Simply put, it is like a The inner pot of the kettle is the same.

The astronauts inside will generate heat during activities. If the heat is not dissipated, the body will continue to sweat due to overheating. This sweat will make the astronauts uncomfortable. Think about it, it is like a sauna. , lying down is okay, but any other movements are powerless.

Therefore, the space suit must have this liquid cooling layer, and it must be close to the astronaut's skin so that the heat can be taken away.

These need to be put on separately. There is a certain gravity on the moon, so it should be easier, but for Carlos, a novice, it is not an easy task.

Carlos kept busy, using his hands and feet, and it took him more than ten minutes to finally put on his clothes. When he walked out, he smiled at the camera: "I never thought that putting on clothes would be so difficult. Taking off clothes would be so difficult." It should be easier to get dressed, especially taking off other people’s clothes.”

In the West, this kind of joke is very common, but in the East, it is a bit vulgar. Considering that Carlos is a foreigner, Zhang Zhong, who was in charge of the commentary, did not say much. Anyway, Carlos was in charge of making fun, and then let him continue. Just be funny.

Then put on the outer lunar landing suit, which was much more complicated. The lunar landing suit was hung on the wall. Carlos wanted to get in from behind, but I don’t know how hard he used it. He turned over and then quickly The ground flips back, like an action movie star filming a martial arts movie.

Carlos failed again, but he didn't care and kept coming!

Fortunately, Pan Chun came to help, and Carlos finally put it on for the third time.

The biggest problem with a space suit with an opening on the back is that he cannot close the chain door at the back, and needs help from his companions. Pan Chun first helps Carlos, and then it is Carlos' turn to help Pan Chun.

Full of distrust, Pan Chun exposed the process in front of the camera, and then the sound of the ground came from inside.

"No, use your left hand to hold the zipper, and your right hand needs to hold both sides of the clothes."

"Don't use too much force!"

"The safety mechanism above is not locked, and the outer layer cannot be operated."

After more than 20 minutes of ground guidance, Carlos finally finished helping.

The next step is to leave the cabin.

"Dear audience friends, we are going to conduct extravehicular activities next. Please enjoy my wonderful performance. Moon, here I come!"

After Carlos finished speaking, he walked towards the airlock and was pulled back by Pan Chun.

"Don't worry, we still have to inhale oxygen and eliminate nitrogen."

If you are a diver, you are very familiar with the operation of inhaling oxygen and expelling nitrogen, and this step is also required in aerospace.

In the past, the interior of the spacecraft was pure oxygen. Later, due to the occurrence of fires, it was gradually changed to a normal environment. Anyway, the outer shell of the spacecraft is hard and the interior is pressurized. You can do whatever you want.

But the space suit is different. This thing is soft. In a vacuum environment outside, if the inside is filled with a gas environment of normal atmospheric pressure, the space suit will turn into a ball, and the astronauts will not be able to move at all.

Therefore, the air pressure inside the space suit cannot be too high. It is generally 0.3 to 0.4 atmospheres, which is basically equivalent to the atmospheric pressure where Mount Everest is located.

If a person is directly exposed to this environment, the nitrogen dissolved in the blood will be quickly released due to the reduction in pressure, just like air bubbles entering during infusion. It can range from joint pain, to stroke and paralysis, to life-threatening. .

Therefore, after putting on the space suit, you need to inhale oxygen and expel nitrogen, discharge the dissolved nitrogen in the blood, and then slowly reduce the air pressure. If this process passes by, then Carlos will not be able to be the first to step on. The man on the moon will become the first man to hang on the moon.

"Okay." Of course Carlos knew how precious life was. In this case, he definitely couldn't do whatever he wanted. Pan Chunrang would do whatever he wanted.

Next, there was another long process of inhaling oxygen and expelling nitrogen. By the time everything was settled, an hour had passed.

After Zhang Zhong explained why he needed to inhale oxygen and expel nitrogen, time passed. Next, the most important thing was about to begin.

Landing on the moon!

Carlos and Pan Chun walked into the airlock.

The lunar module has a standard pressure of one atmosphere, while the outside world is a vacuum, so you cannot open the door directly. Even if you do not intend to use the air in the cabin, you cannot open the door directly. Otherwise, if the door is opened, the two of them will be trapped. The gas is pushed out directly, flying like a cannonball, or it is sucked out by the vacuum.

What's more, the air in the cabin is also very precious and must not be wasted. This requires an airlock cabin. All spacecrafts that carry out extravehicular activities require this device.

The airlock connects the cabin and the outside world. There are doors on both sides. The inner door is open and the gas is connected. After the two people enter, they close the door inside and start to vacuum. When the airlock becomes a vacuum, The door to the outside world can be opened.

This is the final step!

Carlos was filled with anticipation as he listened to the sound of the air pump vacuuming. Although he wanted to get out quickly, he also knew that he must be honest at this time and must not do anything Pan Chun was not allowed to do.

Finally, after the vacuuming was completed, Pan Chun used a mechanical handle to open the outer hatch cover. Mechanical ones are the most reliable.

The moon is right in front of you!

Carlos said to Pan Chun excitedly: "Are the cameras ready?"

"Of course, there are four cameras on the side of our lunar module, which can monitor everything around you and record the scene of you walking down. Carlos, realize your dream in life."

"Okay." Carlos walked forward.

"No, no, we have to exit the cabin backwards!"

If you are walking up the stairs, such as getting off the stair car on an airplane, you have to walk straight on. If there are important people, you have to wave after leaving the cabin door, but those are steps.

There is only an ordinary ladder outside now, so you have to go down backwards. He has obviously practiced more than 20 times on the lunar module simulator, why did Carlos forget it again?

There are no cameras on the moon outside, and there are no reporters carrying cameras. It makes no sense at all for you to go out like this.

Carlos also reacted: he was so excited that he actually forgot about the previous training! So he wanted to turn around and fall down, but at this time he had already reached the cabin door. When he turned around, he failed to control his strength, so, ouch...

An exclamation came from the earphones, and Pan Chun was also nervous. He wanted to go up and help, but there was nothing he could do. Moreover, this exclamation also spread throughout the world.

Everyone saw a scene that made people laugh and cry: Carlos rolled directly from the ladder! His body fell directly onto the moon, with his feet in the air!

Carlos has made all preparations, and he plans to repeat his famous saying: This step is one small step for myself, one giant leap for mankind!

But now, Carlos has nothing to say. His roll is a small roll for himself, but it is a big roll for human civilization?

Fortunately, he was the first to come down.

Pan Chun quickly went down, helped Carlos up, and checked the moon landing suit. If there was an air leak or something, it would be a big trouble.

Fortunately, the extravehicular space suits and lunar landing suits are made of the strongest layer of material on the outside. Not to mention anti-scratch, when necessary, they must even be able to prevent the impact of micrometeorites, plus the gravitational acceleration of the moon. It's only one-sixth of the earth, so even if it falls, it won't be a big problem.

Carlos was fine. With Pan Chun's help, he stood up and searched around to find the location of the camera.

Finally found it, it’s on the side wall, the location is very clear! Carlos stood up and waved to the camera: "Dear viewers, I have successfully stepped on the moon, now I want to take the first step!"

In fact, Pan Chun had already taken several steps, but now he couldn't break Carlos's beautiful fantasy. Carlos turned his head, wanting to take the first step boldly, and then suddenly froze.

His head looked into the distance, and in the direction where the sun rose, he saw a curtain of light like the morning sun!

There is no air on the moon. Where did this scene come from?

Carlos also had a camera on his helmet. As the two went out of the cabin, the live broadcast scene was changed to what the camera saw. The audience in front of the TV was very surprised. What is this?

"We know that there is no air on the moon, but there is dust on the moon. Since there is no air, lunar dust will float on the surface of the moon for a long time. During the process of sunlight, these lunar dust acquire electric charges, repel each other, and rise to the moon Suspended in the sky, such a spectacular charged dust belt is formed, which glows under the sunlight, forming such a magical scene. I believe that when you visit the moon in the future, you will never miss this spectacular scene."

After Zhang Zhong’s explanation, the audience in front of the TV finally understood. Considering that this scene was not filmed during the Apollo moon landing program, it means that the Apollo program was fake!

This moon trip is really exciting.

Carlos looked at this spectacular scene and was a little distracted. Traveling on the moon was indeed completely different from his previous travels. He would never forget it in his life!

Pan Chun went to unload the lunar rover. If you want to detect on the moon, you must have a lunar rover! In this way, you can walk a long circle around the neighborhood. Moreover, this lunar rover is powered by nuclear batteries and has almost unlimited endurance. You don't need to bring it with you next time you travel here.

The lunar rover codenamed Wangshu Zhijin slowly unfolded and turned into the shape of a tractor. It is said that this name has a special meaning, so Max specially chose this name. Only those who are familiar with it will know. This is purely because he does not understand the name. , I thought I was awesome.

However, the name is indeed grand enough, and its appearance is different from other lunar rovers. Other lunar rovers only have four wheels, but it has six, with a big wheel in the middle and small wheels at the front and rear. It can accommodate four people. Now there are only two people, Carlos and Pan Chun. They can sit on one side, and the other side can be used to carry things, such as bringing back soil from the moon.

"Mr. Carlos, we are going to visit the moon!" Pan Chun's voice reached Carlos's ears through the radio, and Carlos looked away from the lunar module's camera and waved his arms: " Everyone, we are going to have a wonderful journey to the moon, come with me."

The video was transferred from the camera of the lunar module to the camera of the Wangshu Chariot. When the car started to move, you could clearly see the traces of crushing and the floating moon dust, which was very spectacular.

This is the moon! I had only seen it in science fiction movies before, but now it finally appeared clearly before my eyes! Carlos was extremely excited. The two billion US dollars were well spent! Money earned is spent.

In front of the TV, countless viewers watched all this, and they were also feasting their eyes. The surface of the moon turned out to be like this! The video is so clear that even if there is a delay, no one will doubt that this is the real moon!

The lunar rover drove to the edge of Rainbow Bay. Here, Carlos and Pan Chun jumped out of the rover. As expected, it was easier to jump forward than to walk forward on the lunar surface.

"Dear viewers, next we are going to install a mirror so that it can be observed optically from Earth."
