"The last test, the results were exactly what was expected!"

Chang'an, Li Bingzhong looked at the report in his hand excitedly, and couldn't wait to share this exciting news with Luo Wen.

"The environmental adaptability test has been completed, and according to the current results, the Long March-9 rocket is fully capable of the next launch mission!"

"No problem with thermal environment testing, no problem with vibration testing, no problem with vacuum testing, no problem with electromagnetic interference testing!"

"The carrying capacity of TIL is up to standard, and the data calculation can reach 82 tons.82 tons! At that time, the TLI carrying capacity of Apollo 11 was only 45 tons! ”

"We've almost doubled-—— and it's not really that simple."

"Without considering the return capsule, what is the concept that the carrying capacity of 82 tons can be used entirely on lunar surface equipment? We can even build a small factory there. ”

"No, no, it's not good for a small factory, but it's no problem to build a life-sustaining system, and it's less difficult to build an Earth orbit space station, that is, our moon base may be improved earlier than Tiangong-1."

Hearing his words, Rowan laughed.

"Mr. Li, are you too excited? No matter what, the space station will be built before the lunar base. ”

"Rocket technology is universal, and compared to landing on the moon, space orbit is much simpler."

"That's different, the space station also has to consider a series of problems such as attitude maintenance, orbit change maneuvering, and spacecraft pairing, but the lunar base doesn't care about these."

"Theoretically, as long as you throw things on it, you can build the entire base with a slightly more agile robot."

"Moreover, the load is so sufficient, we don't even need to worry about it, just design the base as an automatic deployment type, anyway, the landing path has been verified, it's a big deal to fly a few more times, and the cost is not much higher."

"That's not that high."

Rowan said this a little against his will.

In fact, the total investment of the Chang'e-3 project is really not low at all.

Due to the use of metallic hydrogen fuel, which is still extremely expensive, coupled with the significant upgrades to the entire rocket system and landing system, the total cost of this project has reached an astonishing 6 billion RMB, and according to data estimates, the cost of a single launch of the Apollo 11 manned moon landing project was only about 200 million US dollars.

Even if inflation is taken into account, it is still lower than the Chang'e-3 project.

Generally speaking, this project is definitely not "good quality and low price" under the current situation, and it must wait for the resources on the moon to produce benefits before it can be worth its cost.

——

But then again, at this point in time, researchers like Li Bingzhong are actually implementing a new set of standards when judging the "big and small" costs.

That is, no matter how much money you spend now, and no matter whether you can recover it in the future, just whether the money spent can achieve the expected meaning.

Just like the Chang'e-3 project.

Is it expensive?

Is that really expensive?

Can it be recovered in the short term?

Apparently not.

But, does it make sense?

That's a lot of significance.

Therefore, in the face of such a meaning, cost has become the last factor to consider.

seemed to see the ridicule on Luo Wen's face, and Li Bingzhong's expression became serious.

He turned around and said to Rowan in a serious manner:

"Xiao Luo, do you know what is the most meaningful lesson I have learned after being in contact with Xinghuo's correspondent for so long?"

"What is it?"

Rowan asked curiously.

"When the situation is bad, you have to shrink; When things are good, bet hard! ”

"Look at the Spark, 10 years ago, did you hear their names?"

"At that time, the situation was not good, they were the hidden dragon in the abyss, and they were obscure. But since the birth of the J-22, people have been making great progress all the way, daring to fight and fighting, and what has been made in 10 years is enough for us to do it for a lifetime! ”

"Don't talk about it far away, you just said that Chen Gong came this time, you learned the way he did things, right?"

"Two things, a divergence in the direction of the motor rotor and a problem in the algorithm design of the environmental control system, were all decided by him."

"As it turned out, there really wasn't a problem with his decision-making."

"For a long time afterwards, I couldn't figure out why he was so radical, and he must have to achieve the best and the limit of his interests?"

"In the past, we didn't think it was necessary, but we thought that stability was the main thing."

"But now, I have figured out that our country is now on the cusp of a 'bull market'."

"But the bull market doesn't last forever, what if one day, the bull market turns into a bear market? Therefore, we really have to eat all the benefits we can in the bull market, only in this way, can we store enough fat for the winter."

Hearing his words, Rowan nodded slowly.

"If you think about it, our operations in the space field are indeed quite aggressive."

"At the beginning, he put on a posture of linkage with nuclear fusion, and even piggybacked on a handful of the Middle East. It's also a strategy, a 'muscle-flexing' strategy. ”

"Only in this way will it be possible to attract more resources"

"That's right!"

Li Bingzhong nodded with satisfaction.

"It seems that you really figured it out-—— okay, don't talk so much, send this report back to the base."

"I have reviewed all of them, there is no problem with the data, and the module we are responsible for has also passed the acceptance."

"Next, we will wait for the base to complete the final assembly and debugging and start to prepare for launch."

"So fast?"

Rowan asked in surprise.

At this time, it has not been two weeks before the launch of Chang'e-3 and the landing of Yutu on the moon, but Li Bingzhong said that Chang'e-5 is about to enter the launch preparations again?

Of course, the preparations for the launch will not be completed overnight, and according to the current preparation progress of the Chang'e-5 and Long March-9 rockets, the pre-launch testing process will definitely be appropriately extended.

But no matter how much it is extended, it cannot exceed a month.

In other words, within a month, Chang'e-5 will go to the sky again

At this frequency, even the old beauty at the peak can't do it, right?

Li Bingzhong, who was opposite, laughed and replied:

"10,000 years is too short, just seize the day."

"We're not too fast, the fusion guys in the EAST next door are already clamoring to build small tokamaks directly on the moon - and they really argue it, but they are just rejected by their superiors."

"Isn't this pure whimsy? How big of a tokamak are they going to make? ”

According to Rowan's vague impression, the total weight of the new EAST unit, although lower than that of the old unit, has also reached the level of about 400 tons.

This is without taking into account other ancillary energy and power facilities.

If this set is to be carried to the moon, why can't it be more than 2,000 tons?

However, Li Bingzhong's answer gave him a slap in the face.

"According to their arguments, with the use of helium-3 as fuel, including the main body of the fusion device, plus the energy export device, they can do it within .40 tons."

"How much?!"

"How is it possible to do a 40-ton tokamak device?"

In the office in Chengdu, Chen Nian's surprise was not much different from Luo Wen's.

Of course, if you want to investigate the reasons in detail, in fact, the two are still different.

Chen Nian does not think that the technology is unattainable, but the reason why he thinks it is impossible is that under the current limited conditions, the assembly and commissioning of the miniaturized tokamak device on the moon is too complicated.

You must know that there are no large machines on the ground on the moon in a vacuum, and many tools are difficult to use, and it is even more difficult to refine the operation, and the most important thing in a miniaturized tokamak device is "precision".

In this case, it is a bit too radical to rashly propose to build a tokamak device on the moon.

"We also thought it was impossible, so we temporarily rejected it - of course, there was no such link in the Chang'e-5 launch plan."

"The reason why I am asking you now is mainly to hear your opinion and see if it is necessary to carry this device on Chang'e-6."

"After all, judging from the payload that can be achieved so far, the additional load caused by the three astronauts is not much-—— the life-sustaining equipment and resources they need have already been delivered on Chang'e-5."

Hearing Chen Guo's answer, Chen Nian's brows furrowed slightly.

After thinking for a moment, he replied:

"It's not necessary for the time being. Overall, it's a cool idea, but it's just as cool. ”

"Climbing the science and technology tree is not a dinner party, we can't play this kind of snack at every turn, compared with the tokamak device on the surface of the moon, what we need more is a lunar base that can fully meet the survival needs of personnel and has enough anti-risk ability."

"We have to think clearly, according to the current plan, by 2020, we will have 200 permanent personnel on the moon."

"With five years to go, this goal is not easy."

"Engaging in tokamaks is not a big deal in theory, and it doesn't take much load, but the problem is that once we start this way, our overall route is easy to deviate."

"Everything that goes on will focus on realizing the functionality of the tokamak, and it's clear that this is not what we want-—— what we want, and in the final analysis, it is to bring helium-3 back at the minimum cost."

"And it's clear that this idea won't help much in transporting helium-3 – at least not in the short term."

"Understood."

Chen Guo nodded, and then said with a smile:

"Seriously, I also think that instead of making small tokamaks, it is better to get metal hydrogen batteries out first."

"If a large number of solar power units based on metal hydrogen cells can be laid on the lunar surface and the development of the lunar surface industry is really not a big problem."

Speaking of this, Chen Nian's heart suddenly moved.

Yes, when I was engaged in metallic hydrogen, I thought about getting metallic hydrogen batteries.

But at that time, because the source consumption of metallic hydrogen batteries was too high, he had to give up for the time being.

After that, the metal and hydrogen industry began to make great strides, and he felt that there was no need to invest too much in a hurry, and day by day, it was put on hold.

But. What now?

He immediately clicked on the system page, and after entering the relevant information, the latest source point consumption immediately popped up.

120 points!

Compared with the current accumulation of more than 3,000 source points, it has reached the extent that it can almost be said to be given away for nothing.

I can do it!

A smile appeared on his face, and Chen Guo looked at him inexplicably.

At this time, Chen Guo didn't know that a sentence he said casually had once again changed the development process of the history of science and technology

At the same time, Yang Quan.

Zhang Xuemin sat in front of his computer at home, laboriously tapping on the keyboard, searching the Internet for the information he needed.

During this time, he had basically learned all the introductory knowledge related to the moon landing, and then moved on to the more difficult professional level content.

For him, an old coal worker with only a junior high school education, it is not easy to learn and understand these contents, even if he just understands them, but he has never thought of giving up.

Is this a kind of paranoia of his own?

Zhang Xuemin occasionally doubts whether his persistence is right, but after thinking about it, others still have a lot of age to travel and travel around the world, claiming to chase their dreams, and they want to go to the moon without affecting anyone, so it's not a shame, right?

And, no matter what outsiders think, my family is still very supportive of this matter.

Especially the two children, whenever they have time, they will take the initiative to help themselves find information and news, and even hear the ridicule of their neighbors, and they will help to return a few words.

Even the operation of the computer took them days to teach themselves.

It is precisely because of their support that Zhang Xuemin feels that this thing is still worth doing.

And now, Zhang Xuemin's youngest daughter is sitting next to him, watching the contents of the computer screen with great interest.

The limit of human tolerance in a vacuum environment, Dad, what do you think this is for? How unlucky! ”

"Oh, it's better to know more than nothing."

"Hey, you see, I used to think that if I didn't wear a spacesuit in space, people would either explode directly or freeze immediately like in the movie, but it doesn't seem to be like that."

"Well, it seems that our teacher also said that heat dissipation under vacuum is completely dependent on thermal radiation, although the temperature of the cosmic environment is low, but the cooling is not so fast."

"Your teacher is very good, this is all taught!"

"Physics class. Hey, Dad, you said that if you really go to the moon, how long will it take to come back? ”

"Then it depends on which batch I catch up with - didn't you also read the news yesterday, saying that the first astronauts to land on the moon may need to be stationed on it for more than 15 days, and if I catch up with the first batch, it will be 15 days."

"If it's the next batch, then it's not accurate, maybe it's possible in a year or two."

"A year, then you remember to exercise, I heard that after astronauts return to Earth, their bodies will be very weak."

"Don't worry, I can't forget"

The two of you discussed sentence by sentence, and the scene was also very happy.

My wife, who was watching TV in the living room, occasionally glanced at them, which was a little funny, but also felt a special warmth.

These two guys. Seriously.

She shook her head and looked back at the TV, but just then, there was a knock on the door.

She got up and opened the door, and three unfamiliar faces appeared in front of her.

"May I ask if this is Zhang Xuemin's house?"

"Oh, we, we are from the Organization Department and the Propaganda Department of the Municipal Party Committee, and the latter one is from the Armed Forces Department."

"Don't worry, it's a good thing."

"We have something on our side, we want to find Comrade Zhang to understand the situation"
