Chapter 3227: One set of technologies, two solutions
…
"For another example, we know that there is a very important resource, helium-3, on the instrument, which is a very ideal clean fuel in the future. In the past, we thought that helium-3 was widely distributed in the lunar soil. But after our detection, we found that this is not the case.
Yes, the reserves of helium-3 in the lunar soil are also different in different regions.
For example, we have also discovered some unknown elements on the moon, but they have not been confirmed yet. If they can be confirmed, it will be another great discovery in human history.
There are many similar things, and if they can be confirmed, they are all existences that can rewrite textbooks. In addition, these unknown elements may promote the rapid development of human science and technology. For example, many scientific and technological problems that have troubled us in the past may
With the help of these new elements, the problem can be completely solved."
Hearing Wu Hao's words, Jiang Nan nodded and said: "Listening to what you said, I finally understand why the value of these samples is not lower than the gold meteorite core.
But compared to the golden meteorite star core, its presence in the eyes of the public is so low that we can't help but ignore it."
Speaking of this, Jiang Nan immediately said to Wu Hao: "Tell me about the returnable lunar experimental spacecraft that carried out this mission. I heard that this spacecraft is very famous. Can you give me a detailed introduction?"
Hearing Jiang Nan's question, Wu Hao smiled and nodded and said: "In fact, from the name, you can tell that this spacecraft is special because it can return to the earth.
In the past, both the probes we launched and the lunar cargo transport spacecraft were one-way tickets, that is, after they went to the moon, they could not return to the earth.
As for this returnable lunar experimental spacecraft, it can not only go to the moon, but also return to the earth from the moon.
Compared with our previous lunar cargo transport spacecraft, the biggest difference of this returnable lunar experimental spacecraft is that it has an ascender. It is a thruster that rises from the lunar surface to the lunar orbit, and can also be regarded as a rocket on the moon.
.
And compared with the lunar cargo transport spacecraft I launched before, this returnable lunar experimental spacecraft is heavier and can carry heavier cargo.
Take this mission as an example. This time we transported a total of twelve tons of cargo, equipment, and supplies to the moon.
When returning from the moon to the earth, we can also carry more than four tons of cargo. This kind of carrying capacity can only be matched by the Apollo lunar landing spacecraft of the year.
Of course, its biggest difference is that it is an experimental spacecraft, and we will use many new technologies on it. These new technologies will do preliminary technical verification work for our future manned moon landing plan.
So from this aspect, this returnable lunar experimental spacecraft can be regarded as a preliminary verification spacecraft for our future manned lunar landing spacecraft."
Hearing Wu Hao's words, Jiang Nan nodded and then raised questions: "So that's the case, but this is very different from the manned moon landing plan you described before.
In your previous manned moon landing plan, it was carried out in a stepped relay manner, consisting of three independent parts: the manned spacecraft, the Earth-moon transfer spacecraft, and the landing ascender.
Astronauts need to fly into space through a manned spacecraft, dock with the Earth-to-Moon transfer spacecraft in the Earth's orbit, and then use the Earth-to-Moon transfer spacecraft to go to the moon. After reaching the lunar orbit, they then switch to the lunar landing ascender to land on the lunar surface.
.
The same goes for returning, but the order is reversed.
The returnable lunar experimental spacecraft you are talking about now is integrated and takes on all parts of entering space, transferring to the earth and the moon, and landing on the moon.
So does this mean that you have abandoned the original plan and switched to this traditional method of manned moon landing?"
Hearing what Jiang Nan said, Wu Hao couldn't help but give her a thumbs up and said, "That's a very good talk. It seems that you have been studying us a lot in private."
Haha, after we decided to interview you on a temporary basis, we worked overtime to check a lot of information. Jiang Nan said after Tan Cheng.
Wu Hao smiled when he heard this, and then said: "Actually, the two do not conflict. They can be regarded as two parallel projects, or they can be regarded as technical verification projects.
In fact, whether it is this traditional integrated manned lunar landing spacecraft or our relay manned lunar landing system, there are so many technologies used.
So no matter which method of landing on the moon we adopt, these technologies used and verified on the returnable lunar experimental spacecraft can be used.
In addition, scientific research, especially such high-risk detection scientific research tasks, must always have a second plan, which is what we call a backup.
Once a problem or failure occurs in one system, the second plan, that is, backup, must be able to immediately respond.
This is why while we are researching and developing a relay manned lunar landing system, we do not give up on the traditional integrated manned lunar landing spacecraft.
We can use it, but we can't live without it.
After all, the moon is 380,000 kilometers away from the earth. In the future, scientific researchers and astronauts who work and live on the moon for a long time will inevitably bear huge risks.
Therefore, we must not take it lightly when it comes to safety and security, we must be extra cautious. This is to respect and protect them."
Jiang Nan heard this and immediately asked: "But will this be a waste of resources? As you said before, you are a private commercial aerospace company and all funds need to be raised by yourself, so funds are very tight. So under such circumstances, why?
If you still insist on two plans, will this increase your financial pressure?"
When Wu Hao heard Jiang Nan's words, he smiled and shook his head and said: "In fact, it will not be a waste, because the two solutions have many technical similarities, so there is not much that really needs to be spent. So in that case,
Why can't we do two sets of plans?
Besides, although our funds are relatively tight, we are never stingy when it comes to scientific research. We are absolutely unambiguous about the money we should spend, and we will never spend money we shouldn’t spend indiscriminately.”
Having said this, Wu Hao paused for a moment, and then continued: "Actually, there is another purpose of studying this integrated manned lunar landing spacecraft, which is to make up for some of the deficiencies in our segmented manned lunar landing system.
.
The segmented manned lunar landing system operates on a cycle, which also means that if there is an emergency launch outside the cycle, it will be too late and unreliable.
Therefore, this kind of integrated manned lunar landing spacecraft is needed at this time. It is simple to maintain, convenient to launch, and has a relatively short preparation time. It is very suitable for carrying out such short-term and sudden manned lunar landing missions."
