Connecting the control terminal of the industrial robot to Xiao Ai's server, Lu Zhou turned around and left the underground laboratory after instructing it not to tamper with the things he had placed in the laboratory without permission.

The things listed on the list that Xiao Ai gave her were not particularly difficult materials to obtain, and there was no need to go through the trouble of shopping online.

After ordering one in the name of the Institute of Computational Materials, Lu Zhou moved the things to the underground laboratory.

I didn't even bother to say thank you, and Xiao Ai, who got the "new toy", immediately played with great interest.

Lu Zhou, who was standing next to him, saw that it was operating a six-axis general robotic arm, skillfully opened the toolbox, pulled out a hammer from it, and then the other robotic arm picked up an aluminum alloy plate sent by the logistics vehicle, and then pressed it on the cement floor and beat it.

Looking at the mindless operation, Lu Zhou didn't know what it wanted to do.

Listening to the thump, his eyebrows twitched, but after thinking for a while, he finally didn't stop it, just simply said don't spoil the ground, and then turned and left the laboratory.

In two days, he had to go to Beijing for a meeting, and he didn't have time to take care of it for the time being.

Lu Zhou's only thought now is just that he hopes that when he comes back, this guy won't make his laboratory too strange......

……

On the morning of March 6.

A red banner was displayed at the entrance of the school gate of Beijing University of Aeronautics and Astronautics to welcome the convening of the Lunar Landing Engineering Symposium.

The organizers and participants of this meeting are not small, the topics discussed at the meeting are naturally extraordinary, and the security work is also from the school auditorium to the school gate.

With a strange expression, he looked at the police explosion-proof car parked on the side of the asphalt road, and the two young ladies passing by outside the library exchanged their ears.

"Is this a big man visiting the school?"

"No, I heard that it seems to be a manned moon landing or something."

"Manned moon landing?" The slightly tall girl wondered, "When will we be able to land people on the moon?" ”

"I don't know...... However, because I can't board it for the time being, I have to hold a meeting to discuss how to get on it. ”

At this moment, a gentle voice came from the side.

"Student, how should I get to the auditorium of your school?"

Hearing the sound of the conversation, the two girls stopped.

Casting an inquiring glance at him, the slightly taller girl asked.

"You're here for that meeting?"

Lu Zhou nodded: "Well, sort of." ”

The tall girl pointed to the road on the right and continued.

“…… Go straight along this road and turn right at the second junction. ”

Lu Zhou looked in the direction she was pointing, and was about to say thank you, when another petite girl next to her suddenly sighed.

"Wait, you, you, are you the god of land?"

Seeing her excited reaction, Lu Zhou was slightly stunned, and then smiled embarrassedly.

"Call me Lu Zhou or Professor Lu."

I didn't expect to be able to meet the fans on his neck here, it's such a coincidence.

The petite girl looked at him with straight eyes, and said excitedly: "It's quite far from the Great Hall, if you come for the first time, I'm afraid it won't be easy to find, or I'll take you there!" ”

Looking at her enthusiastic appearance, Lu Zhou cried and laughed, "Don't be so troublesome, I'll just walk over by myself." ”

With that, he thanked the two of them, then turned and walked away in the direction the girl had pointed.

“…… It turned out to be the god of land! Looking at the back that was gradually moving away, the petite girl said with emotion, but at this moment, it seemed that she suddenly remembered something, and the emotion on her face instantly turned into remorse, "Ah! I forgot to ask him for an autograph! ”

The tall girl looked at her speechlessly: "What's the use of asking him for an autograph?" ”

"Do you need to ask? Bless me for not failing the course! ”

“……”

……

It didn't take a lot of effort, following the path pointed out by the student, Lu Zhou quickly found the auditorium.

Lu Zhou, who showed his conference card and passed the security check at the door, walked into the venue.

Judging from the logo in the venue, not only the two major central enterprises of Aerospace Science and Technology Group and Aerospace Science and Industry Group, but also Lu Zhou even saw the three giants of BAT Internet and Huawei and other private high-tech enterprises in the list of participating companies.

Affected by Space-X, global private aerospace companies are gradually heating up from unpopular, and China is no exception.

Although aerospace-related technology is basically monopolized in the hands of the two major central enterprises of aviation science and aviation engineering, in fact, after a meeting in 15 years proposed the integration of military and civilian as a national strategy, the relevant policies have been gradually liberalized.

For example, onespace, the first private aerospace company in China, Satellogic, which is quietly invested by Penguin, and the "Tianmao International" communication satellite and the "Candy Jar" mini space station that Ali is expected to launch, etc., the role of private enterprises in the exploration of aerospace technology is gradually becoming important.

We have to admit that in terms of the ability and motivation to explore new technologies and new fields, as well as innovation, the performance of private enterprises is indeed better than that of state-owned enterprises.

Obviously, it is precisely because of this that the top management will gradually open up the relevant market through the means of reform.

Just as Lu Zhou was about to find a place to sit down, someone suddenly shouted his name from behind.

Stopped, Lu Zhou looked back, and saw a man in a suit, about fifty or sixty years old, walking towards this side with a smile.

After staring at him for a while, Lu Zhou gradually remembered his name.

Xu Yuanming, the second-in-command of the Ministry of Science and Technology.

At the commendation meeting of the controllable fusion project, he chatted with this person for a few words.

"Secretary Xu?" Smiled and shook his outstretched right hand, Lu Zhou greeted, "It's been a long time." ”

"Haha, in fact, it's only two months," he shook Lu Zhou's right hand enthusiastically, and after letting go, Xu Yuanming said with a smile, "The meeting is about to start, let's talk while walking." ”

At Xu Yuanming's invitation, Lu Zhou walked with him in the direction of the auditorium.

Along the way, through the conversation with Secretary Xu, Lu Zhou also had a preliminary understanding of the current situation of the domestic aerospace industry.

Especially when it comes to the budget, which he cares about the most.

Overall, the situation is very unpromising.

At present, China's space budget is only about $2 billion a year, and this is the Long March, Beidou, Chang'e, Shenzhou, Tianzhou, Tiangong, and so on combined.

At that time, the total cost of the Apollo program by the United States reached 22.5 billion US dollars, accounting for 0.57% of the GDP of the United States at that time! It's hard to calculate how much that $22.5 billion is worth now, but it was more than enough to build an aircraft carrier battle group at that time.

How much money is burned in aerospace, which can be seen from this!

What's more, there is also industrial heritage and engine technology accumulation...... These are all problems that cannot necessarily be solved by spending money.

Secretary Xu's seat was next to Lu Zhou.

After sitting down with Lu Zhou, he slowly spoke and continued.

"We are not inferior to Western countries in small rockets, but there is a big gap between us and the United States and Russia in terms of the carrying capacity of large rockets."

"The carrying capacity of the Long March 5 is only 25 tons in low earth orbit, only 18 tons in synchronous orbit, and only about 8 tons in Earth-Moon transfer orbit. And our Shenzhou-11 manned spacecraft, the take-off mass is almost 8 tons. Considering that the lunar spacecraft had to be redesigned for the Moon's magnetic environment, and that it had to carry a lunar module weighing at least 3 tons and a living module weighing more than 5 tons, the final weight of the entire lunar spacecraft could exceed the figure of 20 tons. ”

"With our current rocket technology, it is almost impossible to complete a manned landing on the moon."

Lu Zhou nodded thoughtfully.

The engine is a thing that involves a whole set of industrial systems, and this kind of thing cannot be solved overnight. If you want to overtake in a corner, you have to find another way.

At this moment, his heart suddenly moved slightly, and he spoke.

"Why don't you consider an electric pusher?"

"Electric push?" Xu Yuanming was slightly stunned, then shook his head with a smile, "As far as the thrust of the electric propulsion is used to transfer the orbit, it is still too far to use it to launch the rocket." ”

"We can build an electromagnetically accelerated ground-based mass launcher on the ground to deliver unmanned components to low-Earth orbit and then push them to the moon with a plasma engine," Lu continued. ”

It just so happens that the controllable fusion power station has also been built, and the cost of electricity will not be too high, so it is a pity not to use it. While this installation may sound a bit sci-fi, it's not technically impossible.

After all, on the other side of the Pacific Ocean, they have also considered launching satellites with artillery......

Xu Yuanming: "Then how do astronauts go up?" ”

Lu Zhou: "Board the ship from the space station. ”

Huaguo does not have the ability to send people to the moon for the time being, but there is no problem in sending people to space.

As if stunned by this amazing proposal, Xu Yuanming stayed there and didn't speak for a while, and after a long time he smiled and said, "...... It sounds interesting, but it's a bit bizarre. ”

Lu Zhou smiled and didn't deny it.

"Think boldly, be careful to verify. I can't even think about it, how can I achieve it? ”

Xu Yuanming himself is not a technician after all, but because he knows a little bit about the contact at work, he did not continue to discuss this issue with Lu Zhou.

After a pause, he continued.

"At present, our strategic focus is still on the construction of cross-regional power grids and controllable fusion power stations. The top management agreed that it was more important to be down-to-earth and focus on the interests of the present than distant interests. ”

"Many people have proposed to postpone the moon landing until 2030, but the leaders believe that your opinion is equally important, so a compromise plan was discussed at the meeting."

Lu Zhou asked, "A compromise plan?" ”

Secretary Xu smiled mysteriously, and didn't elaborate, but looked at the stage: "The meeting is about to start, and I am just about to talk about this matter, you can continue to read it." ”
