Chapter 129, Early Preparations
Jiuquan Aerospace Center, after the mobilization meeting, the entire space center becomes extremely busy. Every day, aerospace planes continuously take off from here to and from space, sending scientists and astronauts to the "Tiangong" space station in space. , repeated and repeated experiments and inspections on various preparatory work for the manned moon landing activities,
Waves of unmanned spacecraft launched to the moon have already started sending massive amounts of materials to the moon in advance, planning to build a space station similar to the "Tiangong" on the moon.

"Everyone, please take a look. This is the detailed high-definition map sent back by the lunar satellite recently. What we have to do now is to choose a suitable place on the surface of the moon as the landing site. Everyone can express their opinions."

In a conference room, the detailed data of the moon sent back by the lunar satellite is played on a huge monitor, and a pattern of the moon slowly rotates on the monitor.

The scientists below are thinking carefully one by one. Everyone wears a virtual machine on their wrists. All the data has been directly sent to the virtual machine and then directly printed into everyone's minds. You don’t need to look at the screen. At this time, you are looking at the data one by one in your mind.

"Since we are planning to establish a manned base on the moon, we must choose an area rich in resources. According to the data from the resource spectrum detection satellite, the area in the Moscow Sea is quite rich in resources, and here is The basin formed by the impact of the meteorite has a relatively flat terrain, which is also very helpful for future resource extraction."

"No, it's because it's a basin and the terrain is too low, which makes it inconvenient for mining resources in the future, and it's also relatively inconvenient for returning to space."

"The location of the moon landing this time can also be regarded as choosing a location for the future moon base. The selected location should be close to an area rich in resources, and the terrain should be flat, so that we can build a lunar airport later. The Russian Sea is obviously not good here, and the basin is limited. sent our lunar rover to other regions."

"I think the Wells area is quite good. This area has a very flat terrain and relatively abundant resources. It is also close to the lunar equator area. The lighting conditions are quite good and the temperature is not too low. It is also conducive to solar energy equipment. operation and obtain relatively more energy.”

"No, no, although the Wells area is rich in resources, according to the spectrum, the resources in this area are mostly common iron and copper, and there are no precious resources."

"I think the Ocean of Storms area is quite good. There are many kinds of rare resources, and its area is also large enough. It has more than 500 million square kilometers, which is larger than half of China."

In the conference room, a top scientist had a heated discussion on where to choose to land. Because it is related to the relationship between the moon base in the future, the discussion is also relatively intense.

It is necessary to consider not only the future development of the lunar base, but also the difficulty of landing on the moon. Of course, the most important issue is the issue of lunar resources. The lunar base is likely to develop into a frontier base for lunar resource mining in the future. If the nearby If there are too few resources, you will have to go to other areas to mine resources in the future.

It is not as simple and easy to transport materials and mine resources on the moon as it is on the earth. It is likely that the cost will increase greatly if it is only a dozen kilometers away, and this moon base is basically equivalent to declaring that it has occupied a certain area. Whether there are precious resources in the block area is also very important.

If you choose an area with only common resources such as iron and copper, there are a lot of these resources on the earth. Naturally, to mine some resources that are very scarce on the earth, such as rare earths, He3 and other high-value mineral resources.

In the end, after discussions and discussions, the scientists still agreed to place the landing site in the "Ocean of Storms" area, which is a very famous lunar sea area on the moon. It is located on the front side of the moon, which is also the side facing the ground. This area is displayed according to the data detected by the resource detection satellites launched in the past.

The "Ocean of Storms" area is very rich in rare earth resources, and also contains rich He3 resources, and the lunar basalts in this area contain very large iron, uranium, copper, gold, silver and other metals, which can be said to be a cornucopia .

Of course, the more important thing is that this area is a lunar sea, and the interior is very flat, which is very conducive to the construction of a lunar base, and it is also very beneficial to the expansion of the lunar base in the later period. The location is also near the lunar equator, which is very useful for traveling to and from space.

……

In another meeting room, a simulated video was continuously played on a huge monitor. In this video, a lunar landing spacecraft slowly landed on the moon, obviously using old-fashioned jet power.

In this conference room, there are also a lot of scientists who are constantly discussing there. It is obvious that this group of scientists is studying the spacecraft that landed on the moon.

"There is no air on the moon, and there is no runway, so our aerospace plane has no use for it when it reaches the moon. There is no way to directly use the aerospace plane to travel to and from space just like the earth."

"So we must develop a safe and reliable spaceship that can be used multiple times to travel between the moon and space. We can use aerospace planes only after we have established our own runway on the moon base. Directly to and from space."

As top scientists in the field of aviation and aerospace vehicles, Liu Shiying and Li Fu were both assigned to this project team to jointly lead the team to study the spacecraft used to land on the moon and travel from the moon to and from space. The two are in charge of the lunar landing spacecraft people.

In fact, the technical content of the lunar landing spacecraft is not known to be much lower than that of aerospace aircraft. You must know that Yingjiang has already landed on the moon in the last century and returned successfully. The spacecraft technology used has long been difficult for Huaxia. .

However, China's manned moon landing this time is obviously different from the manned moon landing of the last century. This time, China's manned moon landing is not only about landing on the moon, but also building a lunar base on the moon. The materials and personnel transported have far surpassed the manned moon landing in the last century.

Naturally, the requirements for the spacecraft are higher, and it is necessary to use a spacecraft with greater thrust, which is safer, more reliable, stable and capable of continuous recycling. The difficulty has suddenly increased by an unknown number of times.

Unless the base on the moon has been built and a runway for the controllable aerospace aircraft to land and take off can be built, the spacecraft will have been eliminated by then, but there is no air on the moon, and it is impossible for the aerospace aircraft to use air to fly. slow down.

Considering that the gravity of the moon is only 1.633, which is 1/6 of the gravity of the earth, plus there is no air, if there is a runway on the moon, it is very easy and simple for an aerospace plane to take off, but when it lands, it will Very difficult.

One is that there is no air resistance, and it is difficult to land at this speed. However, the gravity of the moon is too low, which also needs to be taken into account. Therefore, in the planning of the future lunar base, an ultra-long runway is absolutely indispensable, and we can only use the runway at that time The friction or design reverse thrust also reduces the speed.

"Li Fu, do you have any good ideas?"

Liu Shiying looked at the many scientists in the conference room, and asked with bright eyes when he saw Li Fu.

"Traditional spacecraft can be used to carry people to the moon, but if it is used to transport materials, the cost will be very high, and it is on the moon. The cost of sending spacecraft by rockets on our side of the earth is now It’s already very high, not to mention it’s still on the far side of the moon.”

"And the resources mined on the moon will definitely be transported into space on a large scale in the future, so I think we should consider designing a cheap aircraft from the very beginning."

"Since there is no air on the moon and the moon's gravity is very low, we can actually consider installing a reverse deceleration thrust engine on the aerospace plane. In this case, I think it should be feasible and can meet the needs of the moon to and from space."

Li Fu continued to ponder in his mind, and after thinking for a long time, he opened his mouth slowly. As soon as Li Fu opened his mouth, he denied the original plan of landing on the moon with a spaceship, and continued to use an aerospace plane. According to the design, a plasma-powered engine is installed in the front, and then reverse thrust will be used to reduce the speed of the aerospace plane, so as to realize the plan to land on the moon.

If it is on the earth, because of air resistance and strong gravity factors, it is obviously not possible to reverse the deceleration engine, because no matter how the engine is installed in reverse, it will seriously affect the streamline of the aerospace aircraft and become Great resistance.

And when the aerospace plane is flying at high speed, because the reverse engine will definitely be instantly blown off by the powerful air, the entire aerospace plane will be destroyed.

But the moon is different. There is no air on the moon, so you don’t need to consider air resistance. It doesn’t matter how your aircraft is designed. This environment is very similar to the environment in space.It's just that there is a gravity factor to be considered on the moon, but the moon's gravity is not very strong.

After listening to Li Fu's words, the other scientists opened their eyes for a moment, and couldn't help nodding their heads. This method is indeed feasible, and it also takes into account long-term problems, not just this manned moon landing.
