"It doesn't matter whether it's too fast or too slow. The engine requirements and overall control are very strict. If the deceleration is too slow, causing the lander to go too fast, the landing speed will increase. Although the gravity on the moon is relatively low, the lander will
It cannot withstand impacts at too high a speed. This is how the lunar surface probe of our neighbor, a large country in South Asia, failed."
Hahaha……
Hearing Wu Hao's words, the leaders present laughed. Indeed, the third brother's spirit of fighting against repeated defeats has infected many people, or at least made many people feel happy.
Why did the detectors at Third Brother's house fail so easily? What was the reason? A leader couldn't help but become curious.
Hearing this leader's question, other leaders also looked at him, and everyone wanted to know why the Sanguo family didn't work.
Hearing this, Wu Hao smiled and said: "Actually, there has been great progress, but there are still some differences in some core technologies.
Especially the vector engine and overall control were somewhat inferior, which led to the final failure.”
"Is this difficult?" one leader couldn't help but ask.
It’s difficult, at least it’s difficult for Third Brother. Wu Hao nodded and replied: “First of all, although Third Brother launches several satellites every year, they lack good rockets, especially high-thrust rockets.
In fact, the take-off quality of Third Brother's rockets is not low, they are several thousand tons, but the carrying capacity is pitifully small, only a few tons, and the good ones are only more than ten tons, which is very poor.
And we know that the core of a rocket is the engine, so they are relatively behind in engine technology. Although they have been constantly learning and absorbing foreign success in the past few years, especially the purchase of a lot of technology from Maozi and some cooperation, so
Their technical level in this area has improved a lot, but it is still far behind the national advanced level.
Let's put it this way, although Maozi's aerospace technology is also very powerful, they are also very poor in this kind of extraterrestrial planet detection technology. Their Mars probe failed several times, and the lunar probe is just like that.
.
Letting him give lessons to Third Brother is like tutoring students with poor grades. What good results can there be?"
Hahaha……
Wu Hao's words directly made everyone at the scene laugh. Indeed, although what Wu Hao said was a little exaggerated, it is indeed a fact. Mao Zi is indeed very unfortunate in this area. How can the apprentices he taught be so good?
.
Why is everyone so keen on going to the moon? People like Third Brother, who is not very financially strong, are also so enthusiastic about lunar exploration. A leader couldn't help but ask.
After hearing this question, everyone started to communicate in a low voice. Indeed, this is something that many people don't quite understand.
Seeing the questioning looks from several leaders, Wu Hao could only answer with a smile.
Actually, there are many reasons, such as political reasons, technological and economic reasons, aerospace development, etc. As far as the third brother is concerned, it is more of the first. To put it bluntly, it is a political need. They want to
It must demonstrate its strength in the aerospace field through aerospace engineering or lunar exploration projects, thereby demonstrating its status as a major aerospace power and a major national power.
In addition, its rulers also hope to use this to increase the cohesion of their domestic people. We all know the situation of the third brother. The hierarchical conflicts are very sharp, so we need to divert everyone's attention. This is why they have been causing trouble for us.
reason.
Nowadays, many countries also regard this kind of moon landing and entering space as a way or tool to demonstrate their country's influence. Many countries develop this not necessarily for actual needs, but may just want to create some movement to show their existence.
In addition, there are actual scientific research needs or aerospace development needs.
We know that the moon is the planet closest to our earth. If we want to explore the universe, the moon is the first step that cannot be avoided. Only by climbing this step can we go up to the second step, and then
Climb up level by level.
Also because the moon is close to us, and is a natural satellite of our earth, revolving around our earth. In addition, it has no atmosphere and its own gravity is too low, so it can be regarded as a stepping stone for us to explore the deep space universe, and it also starts from the deep space.
A portal from the empty universe into the Earth.
Therefore, geographical location is very important. Whoever controls the moon will control our earth's access to the deep space.
To put it another way, the moon is like a port or city on Earth that controls the throats of several straits, such as Shijiapo, Gibraltar, etc.
This is also why everyone is so keen on exploring the moon, and one of the reasons why new scientific research stations and bases are built on the moon.
Speaking of this, Wu Hao glanced at the leaders sitting here, and then continued: "In the end, it is economic reasons. This is also the reason why we engage in lunar exploration and establish a scientific research station on the moon.
First of all, the moon contains rich mineral deposits. In addition to the well-known helium-3 resources, there are also rich manganese, titanium, iron, copper, silver and many other rich minerals. From the composition of some lunar soil explored by our two detectors
From an analysis point of view, there are still many so-called elements from the universe, so they are of great mining value.
With the growth of human beings on the earth, the earth's resources will eventually be exhausted. So where will the resources that humans need in the future come from? It can only be the universe above our heads.
The moon is the closest to our earth, so it is of course the first choice for mining. Therefore, this will be a very promising market.
Of course, these may be too far away, and they will all happen in a hundred or even two hundred years. Let’s talk about something closer, which is also the most precious resource on the moon and the most needed resource by us humans, helium-3.
The moon probably stores more than one million tons of helium-3 resources, but how much does each ton of helium-3 cost in the international market now? It's three billion U.S. dollars. Let's calculate how much it is."
After hearing Wu Hao's words, everyone couldn't help but start calculating silently. The more they calculated, the more excited they became, and finally couldn't help but communicate with each other.
"According to current scientific speculation, controllable nuclear fusion technology will probably mature and be commercialized in the next ten years. Once commercialized, it will require a large amount of helium-3 resources. It is unrealistic to extract and supply close to the earth, and the cost is extremely high.
, then there is an urgent need for helium-3 resources on the moon.
And when the time comes, we only need to transport the helium 3 above, and then we can make a lot of money. Calculated by transporting two tons each time, we can earn five to six billion US dollars each time, and the income is very considerable. It can be said that
