"But why do moonquakes last for such a long time?"

While expressing doubts about this question, Lin Shi calculated directly on the whiteboard beside her.

"According to the density of the moon sample we obtained, assuming that the overall density of the moon is very close to that of the sample, the time of the moonquake should not exceed six minutes at most."

"Lin Shi, there is nothing wrong with your derivation. But we can change our thinking. If these data are all right, what is the reason why the moonquake can last for such a long time?" Xu You said with a smile.

Lin Shi frowned slightly, and immediately thought of a reason.

"Could it be that the inside of the moon is hollow?"

"Yes, it is indeed such a possibility. But in fact, the real situation is closer to the moon's interior where there is a lot of gas and dust. This leads to a very low density inside the moon, which is similar to a 'hollow' state."

"That's right. But this kind of structure should be very rare in celestial bodies. What causes the interior of the moon to have such a structure?"

"Indeed, similar hollow structures are very rare in celestial bodies. Of course, this theory has not been confirmed, it is just our guess. Unless there is more strong evidence to prove the existence of this structure, there is still no way to draw conclusions.”

After all, this hollow structure is difficult to explain in terms of its origin.

If this structure is really the case, there may be more secrets hidden in the formation of the moon.

At this time, Cui Ying said:

"Mr. Xu, the Aerospace Academy has contacted you. Please reply to them if you have time."

Xu You looked at the time and found that he had accidentally chatted with the three astronauts for so long.

"We've been chatting for so long, so we won't bother the three of you any more. Let's get together again when we have a chance next time."

"Okay, Professor Xu, you are also welcome to visit our astronaut training center."

After sending off the three astronauts, Xu You returned to his office and replied to the Aerospace Academy.

"Hi, I'm Xu You."

"Hello, Professor Xu, Johnson from the Sam Space Agency would like to talk to you about cooperation."

Hearing this news, Xu You stared slightly.

"Sam Space Agency... really can't sit still." Xu Youxin said.

Another delayed launch of the moon landing test rocket is obviously about to touch the bottom line of people's patience with the Sam space agency.

If this continues, everyone may doubt whether they will push this project to five or ten years later.

This will have a great impact on the reputation of Sam Space Agency.

The conditions proposed by Xu You, although very harsh for the Sam Space Agency, are also somewhat attractive conditions.

If the problem of rocket liquid hydrogen fuel leakage can be successfully resolved, no matter how many requirements there are, they can be negotiated.

"Okay, I'll go to the Fifth Academy right away."

The fifth hospital is not far from Jijing University. If Xu You starts now, he can reach it soon.

"Okay, Professor Xu, let's inform Johnson first and let him prepare."

After hanging up the phone, Xu You asked Cui Ying to help arrange a vehicle to the Fifth Aerospace Academy.

At the same time, Xu You told Lu Zhiyao that he might not be able to go home tonight.

"Because I don't know how long it will take to deal with this matter. If it's too late, I might just stay there for one night."

"Well, you can go there without worry, if it doesn't work, I'll let Teacher Cui or Lin Shi accompany me." Lu Zhiyao said.

Soon, the vehicle arranged by Cui Ying came downstairs to Xu You's office.

When he arrived at the Fifth Aerospace Academy, Xu You took a break and got in touch with Johnson.

On the other side, Johnson had been waiting for Xu You for a long time, and couldn't wait to start a conversation with Xu You.

"Professor Xu You, congratulations on the success of your moon landing project."

"Thank you Commander Johnson for your congratulations. I wonder if the preparations for the Space Launch System are going well?"

Xu You didn't have too much politeness with Johnson, and directly pointed to the point.

"To be honest, we did encounter some troubles. As you know, the recent weather is really not conducive to the launch of the rocket. This damn weather has forced our launch plan to be postponed."

Xu Youxin said that it's fine to use this excuse on social platforms, but he still played such a trick with himself.

"Commander Johnson, if this is the case, then I don't think there is any need for us to communicate. I don't have any magical powers to solve the weather problem."

Seeing that Xu You wanted to hang up the phone, Johnson hurriedly said:

"Of course, Professor Xu You, apart from weather factors, our space system does have some technical problems. I wonder if the conditions that Professor Xu You mentioned before still count?"

"To be honest, I'm a little disappointed in your performance. It was a problem that could have been solved quickly, but you kept procrastinating until I lost interest in helping you solve this problem."

"Professor Xu You, please understand our difficulties. After all, it takes a lot of complicated procedures to apply for those confidential documents. Now that we have completed the application process, we can send Professor Xu You the materials you need right away. But we also hope that Professor Xu You can fulfill his promise and help us solve the problem of liquid hydrogen fuel leakage."

"Relax, at this point, you don't need to worry at all. If I don't have the confidence to solve the problem, there is no need to waste so much time with you. We have already completed the mission to the moon, and those past materials are not important to us. There is no value to learn from."

Xu You deliberately played down the significance of these materials, and this is indeed in line with the logic of normal cognition.

Except for Xu You himself, no one knew that Xu You had obtained those abilities beyond ordinary people.

"Okay, then I will send these materials to your mailbox now. The decryption method is still the same as last time. I hope that Professor Xu You can use these materials to help us solve the problems of the space launch system."

"I have one more condition."

"Professor Xu You, please speak."

"After the successful launch of the spacecraft, SAM Space Agency needs to thank us publicly."

"Um... well, there's nothing wrong with that."

Johnson pondered for a moment, but still agreed to Xu You's request.

Soon, Xu You received an email from the Sam Space Agency in Xu You's mailbox.

After Xu You downloaded the materials, he copied the materials to another computer that was not connected to the Internet, and opened the files in the attachment with the key.
