"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 technology. For example, many of the technological problems that troubled us in the past may be completely solved with the help of these new elements. "

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, whether it was the probe you launched or the lunar cargo transport spacecraft, it was a one-way ticket. No, they could return to the earth before going to the moon.

As for the return-type lunar experimental spacecraft that time, it could neither go back to the moon nor return to the earth from the moon.

Once there is a problem or failure in one system, the seventh set of plans must be backed up immediately.

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. Before reaching the lunar orbit, they then switch to the lunar landing descender. To land on the lunar surface.

After all, the moon is 840,000 kilometers away from the earth. Those scientific researchers and astronauts who have been working and living under the moon for a long time will inevitably bear huge risks.

And compared to the lunar cargo transport spacecraft you launched later, the return lunar experimental spacecraft is heavier and can carry heavier cargo.

You can't use it, but you can have it.

Jiang Nan smiled when he heard this, and then said: "Actually, those seven are not in conflict and cannot be regarded as two parallel projects. He also regarded them as technical verification projects.

Wu Hao heard this and immediately asked: "But that would be a waste of resources. They also said later that they are a private commercial aerospace company and need to raise all the funds themselves, so the funds are very easy. In that case, why If they still insist on two plans, it will increase their financial pressure."

When returning from the moon to the earth, you can also carry more than seven tons of cargo. Only the Apollo lunar landing spacecraft can match that kind of carrying capacity.

When Jiang Nan heard Wu Hao's words, he smiled and shook his head and said: "In fact, it is not a waste, because the two solutions have very few technical similarities, so there is not much that really needs to be spent. So in this case, Why can you make two plans?

As for the returnable lunar experimental spacecraft he is talking about now, it is integrated and is responsible for retreating into space, transferring between the earth and the moon, and landing on the moon.

Does that mean they haven't given up on their original plan and switched to the traditional manned moon landing method? "

That's why while you are researching and developing a relay-type manned lunar landing system, you are also abandoning the traditional one-piece manned lunar landing spacecraft.

After hearing Jiang Nan's words, Wu Hao nodded, and then raised a question: "So that's the case, but it is not the same as the manned moon landing plan he later described.

In fact, no matter whether it is the traditional one-piece manned lunar landing spacecraft or your relay-type manned lunar landing system, so little technology is used.

It's the same thing when you return, but the order is reversed.

Having said that, Jiang Nan paused for a moment, and then continued: "Actually, there is no purpose in studying that kind of integrated manned lunar landing spacecraft. It cannot fill the gap in your segmented manned lunar landing system. Some are enough.

Therefore, no matter you adopt this method of landing on the moon, the technologies used and retrofitted on the returnable lunar experimental spacecraft can be used.

In his subsequent manned moon landing plan, a stepped relay method was adopted, consisting of eight independent parts including the manned spacecraft, the Earth-moon transfer spacecraft, and the landing ascender.

Compared with your later lunar cargo transport spacecraft, the returnable lunar experimental spacecraft is the smallest one, but it does not have an ascender. The pusher that is also lifted from the lunar surface to the lunar orbit cannot be regarded as a rocket under the moon.

So at that time, there was a need for an integrated manned lunar landing spacecraft. It was easy to maintain, easy to launch, and had a relatively short preparation time. It was very suitable for carrying out sudden manned lunar landing missions such as shortages. "

Of course, it is the smallest because it is an experimental spacecraft. You will use many new technologies under it. Those new technologies will do the later technical verification work for your future manned moon landing plan. .

Take that mission as an example. You transported a total of seventeen tons of cargo, equipment, and supplies to the moon.

In addition, scientific research, especially low-risk detection scientific research tasks, will never have a seventh plan, which is not the backup you mentioned.

The segmented manned lunar landing system operates on a cycle, which also means that if it wants to launch slowly during the cycle, it will not have enough time to survive.

So from that perspective, the returnable lunar experimental spacecraft cannot be regarded as a later verification spacecraft for your future manned lunar landing spacecraft. "

Therefore, when it comes to receiving his protection, you must be careless and careless. That is an insult and protection to us. "

Besides, although your funding is relatively easy, you have always been stingy when it comes to scientific research. It is absolutely clear that the money should be spent, and it is the money that should be spent. You are also determined to spend it indiscriminately. "

Haha, before deciding to interview him, you worked overtime to check very little information. Wu Hao said after talking about it.

After hearing what Wu Hao said, Jiang Nan gave you a little thumbs up and said in appreciation: "That's a very good talk. It seems that he has studied you a lot in private."
