The lunar module of the Chang'e Fleet is completely different from the Apollo spacecraft in the original time. This is actually modified by a small transportation spacecraft. Originally, this small transportation spacecraft was used as a short-distance transport ship at the Tiangong base. In order to save costs, its structure is very simple. It is basically a rocket engine, plus a fuel compartment and a simple control table, and there is no survival device. It must be driven in a space suit. Now after some transformation, it has increased the fuel compartment and the main rocket facing downwards, and it is used as a lunar module.

The five spacecraft are equipped with four of these lunar modules as vehicles to and from the moon surface and orbit around the moon.

After the lunar module landed gently on the moon surface, the cabin door opened and three astronauts walked out. Without saying a word, they started working. They didn't even say anything to the camera like Armstrong, "This is a small step for me, and a big step for mankind!" and other words.

The first person to step out of the lunar module, that is, the first person to land on the moon on this plane was Captain Si Wanli of the Space Force. He was originally from the Air Force, but has now been transferred to the Space Force.

However, Wen Desi had already said this pretentious sentence for them.

When the images of them stepping onto the moon appeared on the display screen, the command center was already full of joy.

"This is just a small step for him, but it is a big step for mankind!" Wen Desi said loudly when Si Wanli took a careful step.

"Paipapapapapapa..." A warm applause rang out from the command center.

Captain Si on the screen took out a terrain photo, looked around, and compared whether he had indeed landed in the predetermined area taken by the satellite before. After confirming that it was correct, he and two companions surrounded him, using their feet and protruding rods on their hands to roughly determine that the ground was strong enough. Then Si Wanli returned to the lunar module to move out a camera and supporting equipment, and after connecting it, he tried whether the function was normal. The two companions took out several panels from the cabin and laid a cross and an arrow on the ground.

At this time, Si Wanli used the radio to call the fleet: "Commander, I am the advance team. The ground has been checked. There is no problem. You can go to the next step."

"Received!" Colonel Chersi, the commander of the fleet, immediately contacted the No. 2 spacecraft. "No. 2, I am Huang Si. Are you ready?"

"It's ready, commander, you can land."

Chang'e-2 started the reverse thrust engine, slowing down the speed. The entire hull landed directly on the moon, with the target being the symbol on the ground. When it reached an altitude of 200 meters, the hull's slow engine was activated and landed slowly on the surface of the moon.

The landing was very accurate and almost landed directly on the center of the circle. This is certain. Those who can be picked out to drive a spacecraft are all the top picks out of the aviation force. This guy used to drive a sea harrier, so vertical landing is not a problem at all.

After the hatch door opened, more than a dozen people walked out of the cabin one after another, two of them driving two electric lunar rovers.

When I first went to work outside the earth, everyone was inevitably a little excited and excited. An astronaut said in the channel: "Hey, the scenery of the moon is too ugly, it is completely different from that seen on the earth."

"Yeah, yeah, it's really ugly, bare and nothing."

"Okay, you are not here to travel, hurry up and work."

Everyone started working immediately, some installed instruments, some drove to explore, and some continued to build landing signs with cloth boards.

"Does the moon landing plan have insurance registrations for astronauts on the moon?" Wen Desi asked.

"Of course there are..." Wen Zebin said from the side: "This is just a routine mission and there is no danger. The spacecraft is equipped with enough oxygen, food and water for everyone to live for two months. Only aid signals are required to be sent out. The subsequent rescue will arrive at up to three days. Even if the personnel cannot be evacuated immediately, there is no problem in replenishing the supply."

With Tongtianqiao and Tiangong Base, you are so confident in lunar exploration.

Wen Zebin continued to introduce his design to his father: "Although these five spacecraft have similar appearances, their internal compartments and functions are completely different. No. 1 is responsible for the round trip between the moon and the Tiangong Base, No. 2 and No. 3 will land on the moon surface, the center of our first lunar base, and No. 4 and No. 5 will become the foundations of the lunar orbit space station."

The astronauts were busy for a long time and selected a new landing area on the ground and laying the landing boards. After captain Chang'e-2 returned to the ship and notified Huang Si: "Commander Huang. It's ready, No. 3 can come down."

Afterwards, Chang'e-3 in the orbit also landed. The other three spacecraft lost a total of 8 lunar modules. After landing on the ground, more than 40 astronauts and more than a dozen robots came out. The astronauts moved out several machine equipment and joined the work ranks on the ground. The robots were also directed by several astronauts to work.

Of course, these robots don't look like humans at all. Some look like spiders, some look like scorpions, and some look like toy cars with robotic hands. None of them looks like humans anyway.

Fleet Commander Huang Si was also among the people. He first looked around and ordered the four spaceships on the orbit to throw the containers down.

A few minutes later, a total of 64 large containers were thrown out of orbit by a spacecraft. After landing at a certain distance, the radio altimeter was activated and the retro rocket installed at the four corners of the container was ignited. Under the action of the rocket, the container slowed down the landing speed. This airdrop method was actually not developed for the moon landing. It was the plan used by the Air Force to drop armored vehicles and paratroopers at low altitudes, and was taken over by the moon landing team.

When the rocket was ignited, the personnel on the ground immediately took over the control and activated several posture adjustment rockets around the container through the radio remote control, so that they could land in a closer place for easy transportation. After the container landed, several people immediately took two electric vehicles to go over. They first found two containers for loading vehicles, drove out six electric lunar rovers from it, and then everyone took the car to drag all the containers back to the spacecraft, opened them, took out things from the middle and moved them into the spacecraft, and assembled some instruments on the spot.

This includes solar panels filled with six containers, totaling 10,000 square meters. After the astronauts moved them out of the container, they immediately began laying and installing them. They will be the main source of electricity for the moon base. At the same time, several machines were also arranged. In addition to the standard detector antennas, telescopes, mirrors and searchlights, electric furnaces, excavators, hole drilling machines and other equipment are all available.

This is the first time that humans landed on the moon on this plane, but it is not just a "lunar exploration". It is definitely not like the Apollo spacecraft in original time and space, just mine a few pieces of ore and go back. China's first landing on the moon was a systematic project, including landing, adventure, base establishment and other work.

The moon's gravity is very low, only one-sixth of the earth, so it's easy to do work, let alone robots. In particular, four crab-shaped transport robots are particularly powerful, and one robot can move a container. These containers are similar to containers, most of which are in very regular shapes.

After emptiing the container, everyone worked together to drag the empty container to the two landed spacecraft, took off the doors at both ends, and arranged neatly into several hollow square and long strip shapes. Then they welded the containers together with electric welding guns, and sealed them with strong glue inside and outside the weld to make them airtight. Finally, four small air lock chambers were installed on the outlet, and they were welded first and then sealed with glue. After that, the gas was poured in to test the airtightness. Then everyone dug soil around, and then piled a thick layer on the container, which was to strengthen the ability of the container shell to block various radiation in the universe and make them a temporary residence point.

"Well, this design is good. The container is the main body of the base room, so it makes full use of transportation capacity and saves costs!" Wen Desi nodded with a smile.

"However, it is precisely because of the cost issue that the shell is not completely made according to the standards of the universe. To be a place of residence, some lunar soil must be added. To be on the safe side, the base rooms of this kind of container are equipped with radiation alarms." Wen Zebin said. "Such rooms are mainly used as warehouses, and astronauts' daily lives are mainly carried out in the main body of the spacecraft..."

On the moon, Huang Si looked around and felt that something was missing. After thinking about it, he suddenly realized that he ran into Chang'e-2, took out a five-star red flag and inserted it on the ground, proclaiming that this place was Chinese territory.

"Baopaopaopao..." This action caused a warm applause in the command center.

"Mr. Wen, this is the moon belongs to our China, and this is our first territory outside the earth..." Major General Lin Feng, the commander of this moon landing operation, said excitedly.

Wen Desi nodded with a smile: "Of course, no one can compete with us, hahaha..." He looked back at the earth at this time and felt a sense of being above him.

When you great powers are still on earth, we are already exploring the sea of ​​stars.

He instructed: "The moon base is just the beginning, it is a dock where we march to other planets and our mineral base, so this base needs to be built..."

Wen Desi had no interest in relying on landing on the moon to show off his national strength. He was only interested in lunar resources, and after he arrived, he did not plan to leave. Chang'e-2 and 3 were the foundations of the first permanent lunar base, and those containers were the various peripheral rooms of the base.

While most people were building houses, several others found a large number of lunar soil, rocks and core column specimens drilled from drilling rigs, totaling about six tons. Because it was a low gravity environment, the actual weight was only about one ton. They slowly moved it to a transport cabin attached to Chang'e-2, and a man drove the rocket to launch the sky, sending the lunar rocky soil specimens back to Chang'e-1.

After receiving the lunar rock specimens, Chang'e-1 started the engine and accelerated the orbit of the moon and returned to the Tiangong base to send the lunar rock specimens. Only Chang'e-4 and 5 were left as the basis for the lunar orbit space station in the orbit of the lunar orbit.

After Chang'e-1 returned, Wen Desi and the big guys who came to visit took the heavenly car to return to Earth. They could not stay on the space station for a long time.

……………………………………………………………………

Although China's moon landing this time was large, it was not publicly or widely publicized, and it was just a low-key one. And it was not enough to go there once. Chang'e-1 returned to the Tiangong base and unloaded the lunar rocks and soil specimens, it would re-mount the container and load the cargo as a transport ship to transport subsequent materials, equipment and personnel to the moon to form regular flights. Later, the flight was added from three spacecraft, with a total of four spacecraft going back and forth between the moon and the Tiangong, ensuring that at least one spacecraft could travel back and forth every day.

When the Earth is connected to Tianfeng and Earth, the retrieved lunar rock specimens will be used for analysis, and then compared with the on-site analysis data of the instrument brought by Chang'e-3 as the basis for design of resource evaluation and refining equipment. As for the name of the first lunar base, it is named "Guanghan Palace".

After the construction of the Guanghan Palace base was completed, the astronauts ran around on electric lunar rovers to conduct subsequent search and exploration, and retrieve samples from various places. Three months later, the lunar exploration team drew a resource distribution map centered on Guanghan Palace and within 1,000 kilometers.

The moon's mineral resources are very rich, especially the storage of some rare metals is greater than that on Earth.

For example, the rare earth elements, uranium and thorium, which are relatively rare on the earth, are everywhere on the moon. Krip rock is one of the three major rock types in the lunar highlands, which are rich in potassium, rare earth elements and phosphorus, as well as thorium and uranium. Krip rock is widely distributed on the moon. Krip rock in the Storm Ocean region rich in thorium and uranium is covered by the late moon sea basalt. Krip rock mixes and forms high foci and uranium substances, and its thickness is estimated to be 10-20 kilometers. The total amount of rare earth elements contained in the Storm Ocean region is about 22.5 billion tons to 45 billion tons. The rich thorium contained in the Krip rock is also one of the important mineral resources for humans to develop and utilize lunar resources in the future.

Common materials, metals, are also very rich on the moon. Take iron as an example. Sand soil of only 5 cm thick on the surface of the moon contains hundreds of millions of tons of iron, while the entire moon surface is 10 meters thick on average. The iron on the surface of the moon is not only extremely rich, but also convenient for mining and smelting. In addition, the iron ore on the moon mainly exists in the form of iron oxide, which is quite pure. When smelting, just separate oxygen and iron.

However, according to the evaluation of the Chang'e task force, lunar mining is unprofitable in the short term. The reason is that the freight costs of lunar resources to be mined to transport to the earth are too high, and the cost cannot be compared with the earth's resources. In fact, it is not just lunar resources, but most space resources are like this at this stage. Unless they are processed into materials or tools that cannot be produced on the earth, such as foam metals, it is unpaid.

Not to mention transporting back to the earth, even if it is smelted out metals on the moon and then transported to low-Earth orbit as material, it is not worth it. This is much more expensive than smelting metals on the earth and projecting them on the orbit with a bridge. Therefore, although the moon has a rich amount of metals, it is still a bit unrealistic to use them on the earth. The cost is high.

Therefore, in the early 21st century of original space-time, when the United States proposed "returning to the moon", it only focused on the helium 3, which is the scarce resource of the earth. Compared with other resources, it is cost-effective to develop helium 3 on the moon, because with the same power generation capacity, the cost of using the lunar energy helium 3 is only 10% of the current cost of nuclear power plants. For example, based on the oil price, the market estimate of helium 3 was about US$8 billion per ton. They estimated that all costs of mining helium 3 on the moon surface, refining, and transporting it back to the earth was US$200 million per ton, which is definitely a super "gold mine" on the moon.

Helium 3 is good. Helium fusion using deuterium and helium 3 can be used as the energy source of nuclear power plants. Moreover, this fusion reaction will not produce neutrons, but will only produce protons without radioactivity. Therefore, when using helium 3 as energy, it will not produce radiation and will not cause harm to the environment. This is a safe and pollution-free nuclear fusion, which is easy to control. It can not only be used on ground nuclear power plants, but also is particularly suitable for space navigation.

However, helium 3 on the earth is very scarce. In the entire earth's atmosphere, helium only accounts for 5% of millions of them; helium 3 accounts for only 14% of these helium. Even if all helium 3 in the earth's atmosphere is separated, it is only 500 kilograms, and if it is added to Shanghai water and soil, it is only 15 tons. However, the situation on the moon is very different. Since the moon does not have the protection of a global "dipople magnetic field", the solar wind containing rare gas ions such as helium, neon, argon, krypton can drive straight in and continuously hit the moon surface, making the lunar soil rich in helium 3. The reserves of helium 3 in the surface soil of the moon are estimated to be 500 million tons! More than 1 million tons are easy to mine.

According to the current energy use of the earth, about 30 tons is enough for the whole of mankind to spend one year. Even if we consider future development and population increase, just the part of helium 3 that is easy to exploit is enough for mankind to spend thousands of years.

However, it is still a little early to large-scale mining of helium 3. After all, the technology tree of fusion reactors is too high. Even if China on this plane has Wen Desi's cheating, there is no research on fusion reactors, and it is still in the laboratory stage. According to the current progress, it will take at least five to ten years to achieve a breakthrough and commercial promotion. Therefore, in the short term, at most a few kilograms of helium 3 will be mined and sent back for the Fusion Research Institute as experimental material.

However, according to Wen Desi's habit of littering goods, he is now planning to gradually develop helium 3. Even if it is not necessary, it can be thrown into the warehouse. Anyway, this is not food again and it cannot be damaged.

Of course, some methods can be used to improve the high freight costs of lunar resources. For example, establishing a mass projector on the lunar surface can greatly reduce transportation costs.

Since the gravity of the moon is only one-sixth of the earth, and more importantly, there is no atmosphere, even with the specifications of the overpass, it only takes 110 kilometers to build a length of 110 kilometers. Moreover, because the vacuum is higher than that of the earth, the huge series of pumping and operational heat dissipation is completely omitted. Therefore, the cost of the construction is much lower than that of the Earth's celestial road, and the cost of the entire 100 kilometers is estimated to be no more than 1 billion Huayuan.

In addition, there is a more extreme approach, that is, do not adopt the 2.75G low acceleration projection mode of the overpass, but uses a high acceleration projection mode with higher G numbers. For example, increasing the G numbers to 30G projects, the orbit length can be reduced to within 11 kilometers and the cost can be compressed to about 100 million Huayuan. Of course, this approach will cause the moon base to lose the ability of projectors and conventional instruments, but there is no problem if the moon is just used as a mine to project minerals or metal blocks.

However, even so, the moon as a mine is only one of the targets of China's space mines. The reason is simple, because the moon's comrades have a very strong competitor, that is, the "near-Earth asteroid cluster".

Because there is no gravity on the asteroid, the transportation cost is lower than that on the moon. If a mining station can be established on the asteroid to extract metals, and a light mass projection orbit can be established, and the smelted metal blocks will be continuously launched back to the Earth-Moon System, then the cost will be much lower than mining from the moon and then launching it into the orbit. Although the metal blocks that advance by inertia may take several years to fly after launch, and only be captured by tugboats after entering the Earth-Moon System, they can be launched every day, and then they will be lost every day to receive packets.

Of course, this is also conditional, that is, it is necessary to wait until a smelter and mass projector can be established in the asteroid belt. This will take a long time and depends on the development of aerospace technology. However, for now, the exploration of the asteroid belt has begun.

Therefore, China's current plan for the moon is second-class, mainly as a large experimental base and space factory, as well as the first stop for human interstellar navigation and a transit station for interstellar migration. The surface of the moon has a high vacuum, no magnetic field, stable geological structure, weak gravity and a high clean environment. The back of the moon is not disturbed by Earth's radio waves. Establishing a lunar astronomical observation base, biological products and new materials laboratory, has great political and scientific significance for earth observation stations and deep space exploration outposts. The moon is also an ideal place to study lunar science, astrochemistry, space physics, life sciences, earth observation science and material science.

Establishing an astronomical observation station on the moon can be unlimited by the earth's atmosphere, and the band can be observed from Kama rays all the way to the long radio band. An interferometer array of any band can be set up on the moon, and the quiet environment on the moon can ensure its measurement accuracy. Some astronomical phenomena such as supernova explosions and Kama ray bursts can be observed and studied in different bands.

According to the detection results, there is water on the poles of the moon, with a total amount of more than 500 million tons, which means that water is not short of water. Moreover, after electrolyzing the water, oxygen and hydrogen will be obtained, so oxygen is not short of it. Therefore, there are much less materials needed to be transported to the Guanghan Palace base.

As for energy, there is no shortage of energy. On the moon, the cheapest energy is solar energy. Since the moon has no air, the sun can directly hit the moon without being blocked and attenuated. Therefore, the solar energy has high intensity and high efficiency. At the same time, the moon's rotation axis is basically perpendicular to the ecliptic surface. As long as a solar photovoltaic power generation base is built on the moon, it can provide very rich and cheap electricity.

And don’t forget that there are a large amount of uranium mines on the moon. It is not cost-effective to transport these things back to the earth, but it is still cost-effective to build a fission nuclear power plant on the moon. And there is no need to worry about pollution like the earth.
