No matter how people in the live broadcast room discuss, it will not affect the live broadcast process. After the lunar probe landed on the moon, the downward camera that originally provided video signals was directly pushed onto the moon's surface, and nothing could be captured except a small amount of lunar soil. The staff responsible for processing the return signal seemed to realize this and switched the live broadcast signal to the return signal of the camera directly in front of the lander.

The first thing that appeared in the picture was a yellowish moon dust, just like the dust captured in a sandstorm. As time passed, the dust blown up by the engine gradually fell back to the moon, and the pictures sent back became clearer. In the near distance was a dark gray moon soil, with rocks of different sizes dotted in between. In the distance, there was a crater formed by a meteorite impact. In the middle of the crater, there seemed to be a very large meteorite, which was brown in color and somewhat out of tune with the grayish-white surroundings. At the top of the picture was a dark space of the universe, deep and dead silent. Looking at it for a long time, it was easy to feel despair.

At this time, Du Qingqing and Qiao Ruida had finished celebrating and returned to their seats. Seeing the real image of the moon, Du Qingqing covered her mouth in surprise and muttered to herself: "This moon is too desolate, except for the lunar soil, there are only rocks. And the colors are too monotonous, either gray or white. If you don't know, you would think you have returned to the era of black and white silent films."

Qiao Ruida also came to the laptop, looked at the moon image on the screen, and said, "The real moon looks like this. There is no air on the moon, and it does not emit light. The surface of the moon is nothing but lunar soil and lunar rocks. It is normal to be in such a desolate state as shown in the video. But there are also surprises. If you look at the middle of the picture, there is a very large meteorite in the center of the crater. It is brown in color, which is very different from ordinary lunar rocks. They are completely different. This kind of lunar meteorite is of great scientific research value. After our helium-3 extraction plant is built, we can send mining vehicles to take a look, in case we discover new elements or new substances."

"We noticed that a small part of the upper part of the live broadcast screen appeared to be a deep black. Looking at this position, it should be the sky on the moon. If I remember correctly, the Mare Imbrium region of the moon is experiencing lunar day at this time. How could the sky appear so dark?" Du Qingqing pointed to the dark area above the live broadcast screen and asked.

This question is a bit deep, but it doesn't bother Qiao Ruida. He organized his words and said to the camera: "The Mare Imbrium region of the moon is indeed experiencing lunar day, which can be seen from the lunar soil and lunar rocks illuminated on the moon. As for why the moon's sky is black, it's a long story. You must first understand why the sky on Earth appears blue. This is because there is a very thick atmosphere on Earth, and the atmosphere scatters sunlight. The earth is surrounded by the atmosphere. When sunlight enters the atmosphere, air molecules and particles will scatter the sunlight to all directions. The wavelength of sunlight is the longest in red light, and the wavelength of violet light is the shortest. Red light and other colored light with longer wavelengths have the strongest transmittance and can directly pass through the particles in the atmosphere to the ground. Blue, indigo, and purple light with shorter wavelengths are easily scattered by particles in the atmosphere. In the short-wave band, blue light has the highest energy and the most scattered light waves, so the sky we see appears azure blue. The clearer the weather, the bluer the sky will be. This is because there are more dust particles, small water droplets and ice crystals in the air on clear days, and more scattered blue light is also generated.

As we all know, there is no atmosphere on the moon, and the sunlight shining on the moon does not scatter at all, so the sky on the moon presents the most primitive background color of space - black. "

"Oh, so that's how it is. Does that mean that all planets with atmospheres have blue skies?"

"Of course not. The color of the sky is related to the composition of the planet's atmosphere. For example, the sky on Mars is yellow-brown, and it is slightly pink in the early morning and evening. The color of the sky on Mars is different from that on Earth, mainly due to its atmospheric composition and climate conditions. The atmosphere of Mars is mainly composed of carbon dioxide (about 95.3%), which is thin and cold, with craters, canyons, sand dunes and gravel, and no stable liquid water. This atmospheric condition causes the sky on Mars to appear yellow-brown. In the early morning and evening, due to the exposure and scattering of sunlight, the sky will be a little pink."

While Qiao Ruida and Du Qingqing were chatting and doing science popularization, the lander in the live broadcast slowly retracted some of its support legs and lowered its height. Then a door opened on the front of the lander and flipped down, forming a slope for the robot and the lunar rover to go up and down.

A few minutes later, a strange-looking robot with two hands and six legs came out of the lander. When this multi-legged robot was fully presented in the live broadcast, there was a commotion in the live broadcast room.
"What the hell is this, a headless centaur, a multi-legged robot, or an alien living on the moon?"

"This thing should be classified as a hexapod robot, but this is the first time I've seen a hexapod robot with such an abstract shape."

"This robot is so ugly. Ruida Aerospace has such advanced technology, why doesn't it build a humanoid robot to land on the moon?"

"That's why you don't know your business. Among the various robot forms, humanoid robots are the most difficult to develop. Just a balance algorithm for bipedal walking can stop more than 90% of robot development companies. Multi-legged robots are different. They are easy to develop, have high stability, strong load-bearing capacity, and are durable. They are the best choice for lunar robots."

"Hey, what is this robot holding in its hand? It's square, like a box?"

"This should be a camera. Don't you see a round protrusion on it? That's probably the lens. And the robot is holding something in its other hand. Judging from its shape, it should be a folded tripod. This multi-legged robot is probably going to set up a camera to provide a second perspective for the live broadcast."

"Reida Aerospace is really thoughtful and knows what people like to see. With this second camera position, we can see the whole picture of the lander."

As netizens had guessed, the multi-legged robot came to the front of the lander with the things and stopped about 50 meters away. Then it set up a tripod and installed the camera on the tripod, with the lens just pointed in the direction of the lander. Then the multi-legged robot turned around, picked up a solar panel and a palm-sized battery from its back, and connected them to the camera. After completing the line connection, the robot checked again to make sure there were no errors, then pressed the power button to test the image capture. There was no problem with the equipment or the line, so the camera naturally lit up. At the same time, the wireless module on the camera also started working automatically, connected to the local LAN, and transmitted the captured video signal to the lander, and then encrypted and compressed it uniformly, and sent it to the Earth's Ruida Space City via radio waves.

The staff saw that the newly added camera captured clear and stable images without any flaws, so they switched the live broadcast room's screen to the signal of this new camera. With the help of new tools and perspectives, a group of netizens in the live broadcast room saw the full picture of the lander for the first time. In the desolate and silent background, the lander is like a lonely explorer, landing steadily on this dead land. It is designed to be simple and sturdy, and the surface is covered with a layer of dark gray high-temperature resistant material to withstand the drastic temperature difference in space. The overall structure of the lander is a pyramid-like structure with a large bottom and a small top. The front is sprayed with the five-star red flag and the logo of Ruida Aerospace, which is particularly eye-catching against the backdrop of the sun.

There is no air or living things on the moon. Time seems to have stopped here. Only the communication signals of the lander shuttle through the universe, conveying human curiosity and will to explore to the distant moon. In this silent world, the lander is like a seed of hope, foreshadowing human beings' continuous pursuit and exploration of the unknown world. "Seeing the five-star red flag appear on the surface of the moon again, my heart is still so excited. Chinese astronauts, well done!"

"The last probe to land on the moon was Chang'e 01, which belonged to the Chinese national team. The probe that landed on the moon this time was YC-, which belonged to the Chinese private enterprise Ruida Aerospace. Ruida Aerospace has become the world's first private aerospace company to successfully launch a lunar probe, and will be forever recorded in the annals of world aerospace history."

"It's a pity that Ruida Aerospace is not listed. If it were a listed company, with such good news, its stock price would have doubled."

"Even if Ruida Aerospace is not listed, there are still surrounding supporting companies. Even if these companies are not listed, there is still the entire aerospace sector. The future market is quite promising."

"Forget about the stocks of other companies. Our A-shares are too volatile. There are many market-manipulated stocks, monster stocks, and junk stocks. I don't want to throw my money in and be ripped off."

"Hey, look, look, there's something new coming out. This time it looks like a lunar rover with wheels."

"Don't you see the bucket and truck bed installed on the vehicle? I think it looks more like a construction vehicle, and it's unmanned."

"Don't make blind guesses. This is clearly a mining vehicle. Didn't you hear what Mr. Qiao said earlier? One of the main missions of this lunar exploration spacecraft is to try to mine and purify helium-3."

"Actually, this car is pretty cool, with smooth lines, full functionality, and a very high-tech feel."

While everyone in the live broadcast room was discussing endlessly, on the live broadcast screen, a car and a robot came together and began to level the land and lay the foundation in front of the right side of the lander to prepare for the subsequent construction of the helium-3 extraction plant. The mining car put down the bucket and drove at full speed to level the land. The multi-legged robot used a pair of flexible mechanical arms to pick out large and small stones and throw them where they would not get in the way. The two machines cooperated with each other and worked very efficiently.

At this moment, Du Qingqing, who had been silent for a long time, finally remembered her explanation task and quickly asked, "Mr. Qiao, judging from the live broadcast, this car and robot are leveling the land, right? Do they want to build a factory here? Where will the building materials come from? They can't bring them from Earth, otherwise the cost will be sky-high."

"Yes, you read that right. They are indeed leveling the land and building a helium-3 extraction plant. As for the source of building materials, of course it is most convenient to use local materials. The professors at our Reda Institute have developed a soil adhesive. You only need a small amount of this substance, mix it with the lunar soil, stir it, pour it into a mold, and let it stand for a while. It will solidify and become the best building material. This is an epoch-making invention that can greatly reduce the difficulty of developing the moon."

"Can this adhesive be used on Earth? If it can be used, wouldn't the building materials market face a huge impact?"

"Special adhesives can be used normally in the extremely harsh environment of the moon, and there is no problem using them on Earth. However, this special adhesive is very expensive. No one can afford to use it to replace ordinary building materials to build high-rise buildings."

In the next hour, the mining vehicle and the multi-legged robot completed the work of leveling the land and laying the foundation with amazing efficiency. Then the multi-legged robot dragged out a device similar to a concrete mixer and several boxes of special adhesives from the inside of the lander. Next, the mining vehicle was responsible for shoveling up the lunar soil and pouring it into the mixer, and the multi-legged robot was responsible for pouring the appropriate amount of special adhesive, and then pressed the switch, and the mixer began to rotate.

While waiting for the raw materials to be mixed, the multi-legged robot was not idle. It entered the lander again, dragged out several sets of aluminum alloy molds, propped them up on the foundation, and inserted some thin steel bars into the molds to serve as the skeleton. Ten minutes later, the lunar soil and adhesive were mixed in place, and the multi-legged robot operated the equipment to cast the wall. In just five or six minutes, a wall more than one meter high and more than five meters long was cast. The next step is to wait for the mixed material to solidify, which takes about half an hour. Of course, during this period, the mining car and the multi-legged robot can also perform a second pouring according to the above process to maximize the use of time.

Thirty minutes later, the second five-meter wall was poured, and the first poured wall was almost solidified. The multi-legged robot walked over and removed the mold, revealing a gray-white wall inside. The multi-legged robot used tools to test the strength of the wall. The results showed that the hardness of the wall was not inferior to concrete, and the thermal insulation, heat insulation, and sealing performance were more than three times higher than concrete.
