The demand for energy in China is urgency, but it does not exist for aerospace.

Even if the success of the controllable fusion project saves the country more than two trillions of energy costs per year, the money cannot be placed on aerospace projects.

Wherever money is spent, what role it takes, it is necessary to go through a rigorous process to make decisions.

Especially with the solution of the rocket recycling technology, the launch cost is not as it used to be.

Taking the launch of a low-Earth orbit satellite as an example, according to international quotations, the Spae-x Falcon rocket has been able to achieve $1,141 per kilogram, compared to the $1,740/kg of the Delta 4 rocket designed by Nasa in the 1990s. In terms of cost, it has been cut by nearly ten times.

The launching cost of the fast-paced No. 1 rocket in Huaguo, which is currently the most commercially advantageous in the world, has dropped from 10,000 US dollars per kilogram to about 5,000 US dollars.

If a manned mission to the moon requires a spacecraft with a mass of about 50 tons to be sent to low Earth orbit, ignore the fact that the spacecraft is not a satellite and cannot be sent to the sky ten times. The launch cost can theoretically be controlled to within $250 million.

Therefore, it is only necessary to build a quality projector at all for the purpose of boarding.

However, what Lu Zhou thinks is not just to send people to insert a flag, but to establish a semi-permanent or even permanent scientific research station on the moon, or even a resource exploitation base.

Considering this long-term goal, it is quite necessary to transfer mass from the surface to the low-Earth orbit outside the atmosphere using a theoretically lower-cost launch.

If chemical-powered rockets have been used, when the number of launches has exceeded 1,000 times, and even rises to the order of 10,000 times, space exploration has truly changed from scientific research activities to an industry, not to mention the problem of cost. It is enough to cause headaches.

It is to be understood that nitrous oxide and dimethyl hydrazine are poisonous.

Of course, Lu Zhou also knows very well that this kind of trillion-level project is impossible to convince the elders with an idea, especially in space projects that do not have urgent needs.

However, I believe that after he has produced enough results, what he said should be more convincing.

The meeting was divided into two parts. In the morning, it was announced at 12 o'clock to announce the intermission. After eating a simple meal at the middle of the meeting, the meeting continued until one and a half minutes later.

In the afternoon, this part of the conference was mainly the home of researchers and engineers, and the content of the discussion was mainly concentrated in the technical field.

At the meeting, the representatives of the major research units spoke enthusiastically and put forward their own views.

In addition to the Hangche Group's concept map of the Long March 9 rocket, many people have come up with interesting technical ideas.

For example, the high-level researcher of the Space Science and Applied Research Center of the Chinese Academy of Sciences showed that the model of the plasma engine is not only different from the idea of ​​Lu Zhou in the details of the acceleration technology, but also a very interesting idea.

In this meeting, Lu Zhou’s speech was not too much. He simply said his idea about the technical route of the Hall thruster.

Some of this was his own point of view, and the other part was his thoughts during a chat with researchers at the af-mpd project team during his tenure as a consultant at pppl Labs.

Originally, he thought that his point of view was already avant-garde. As a result, he did not expect that some people's opinions were more sci-fi than him, and he even gave the idea of ​​no working quality advancement to the meeting.

In fact, no work can be promoted to science fiction, at least nasa has done research in this area, and even related papers can be found on arixv.

After all, no one dares to say anything about the future is absolute. Even the most outstanding scholars dare not make an "absolutely impossible" assertion of the "future", even though those things seemed incredible at the time.

But in any case, the lack of quality to advance such distant things is not a topic of this era.

Everyone heard it and just smiled, not going too far.

There is no jealousy in this kind of seminar itself. Basically, it is free to speak. Everyone can say anything, and there is no such thing as a bar that only refutes the theory.

As for the last adoption of that technical route, it is natural to see the results.

That is, by the middle of the year there will be a tender meeting to tender for the most critical heavy-duty spacecraft in the moon landing plan.

Whether it is a rocket or a space shuttle, who can deliver at least 30 tons of payload to the Earth-Moon transfer orbit and safely come back, whoever has the hope of winning the bid.

At present, the most promising to undertake this important task is probably the Long March 9.

However, the first flight time in 2028, even if it is not extended, is still eight years away.

If the national moon landing project intends to complete the manned mission to the moon within five years, in order to achieve the strategic goal of containing the United States and Europe, the Long March 9 that is still in the design stage will probably miss the battle.

In this context, if other companies can come up with a lower-cost, higher-priority launch solution, they are also competitive.

Do you want to join in this excitement...

In fact, Lu Zhou has not thought too much.

For the electric propulsion engine, he is only in the research stage. It does not say whether he can reverse the technology in the wreckage. It is still difficult to say whether it can be used in the atmospheric environment after the reverse.

Can you say that this kind of highly civilized spacecraft is itself assembled in a space station or a space port? There is absolutely no need to consider what is going to break through the atmospheric environment and launch into orbit from the surface.

This possibility is completely present.

In short, before he has absolute certainty or a clear expectation of the realization of technology, what he said is only to express his own views. As for the bidding project at the end of the year, he probably won’t participate...

After the meeting, Lu Zhou came out from the venue.

At this time, he suddenly discovered that the people around him had more than one circle when he first came in.

Judging from the long guns and short guns that they are carrying, there are no need to guess these people, no doubt they are journalists.

When the representatives of the enterprises such as Penguin and Ali had just stepped out of the venue, the reporters suddenly swarmed like a shark smelling a scent.

Looking at the movements of these reporters, Lu Zhou’s eyebrows couldn’t help but jump. However, it’s not that he was lucky enough to be surrounded by it. Soon, there were sharp-eyed reporters who found him here, and suddenly he’s surrounded. Come up.

Even if Wang Peng was in front, a single microphone was drilled through the pins.

"Hello Professor Lu, we are reporters of the NetE-News Technology Channel. I heard that the re-launch of the manned moon landing plan in China is your proposal?"

"Hello Professor Lu, we are reporters from the Penguin News Technology Channel. Online rumors that China will soon realize space travel. What do you think?"

"... Someone is rumored to be the chief designer of the manned space program. Is this true?"

The scalp that was asked by the ensuing question was numb, and it was impossible to see through the breakout. Lu Zhou immediately caught a reporter who was closest to him, and he went back and slammed back: "Fake."

Reporter: "Hey... then, please ask"

Taking control of the initiative, Lu Zhou took a deep breath and said rigorously: "Restarting the manned space program is not entirely because of my suggestion, but the country does have a strategic need in this regard. As for the manned moon landing design Teacher, I don't know where you heard the news, but as far as I know, the relevant departments only invited me to serve as a consultant."

However, at this time, I did not know when to go next to Xu Shuji next to him, and smiled and added a sentence: "It is the general counsel."

General counsel!

This short three words completely detonated the atmosphere of the scene...-

Thanks to the book lord "The Feather of the Ming" for the reward of the lord~

I feel that I owe more and more debts. I can’t fish any more this month...qaq
