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

While Lin Shi expressed doubts about this issue, she directly made calculations on the whiteboard nearby.

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

"Lin Shi, there is nothing wrong with your derivation. But we can change the way of thinking. If these data are all correct, then what other reasons could cause moonquakes to last for such a long time?" Xu You

Said with a smile.

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

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

"Yes, it is indeed such a possibility. But in fact, the real situation is closer to the fact that there is a large amount of gas and dust inside the moon. This causes the density inside the moon to be very low, almost like a 'hollow' state."

"I see. But this kind of structure should be very rare in celestial bodies. What is the reason why the interior of the moon has 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

There are ways to make a conclusion.”

After all, it is difficult to explain the cause of this hollow structure.

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

At this time, Cui Ying said:

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

Xu You looked at the time and realized that he had accidentally been chatting with the three astronauts for so long.

"We've just been chatting for so long, so I won't bother you three any more. Let's get together again when we have another chance."

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

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

"Hello, I am Xu You."

"Hello, Professor Xu, Johnson from Sam Space Agency wants to talk to you and wants to discuss cooperation."

Upon hearing the news, Xu You's eyes widened slightly.

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

Another delayed launch of the moon landing test rocket has obviously reached the bottom line of people's tolerance for Sam Space Agency.

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

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

Although the conditions proposed by Xu You are very harsh for Sam Space Agency, they are also somewhat tempting.

If the problem of rocket liquid hydrogen fuel leakage can be successfully solved, then any request can be discussed.

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

The distance between the Fifth Academy and Jijing University is not far. If Xu You sets out now, he can reach it soon.

"Okay, Professor Xu, let's notify Johnson first and let him get ready."

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

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, just feel free to go there. If it doesn't work, I'll ask Teacher Cui or Lin Shi to accompany me," Lu Zhiyao said.

Soon, the vehicle arranged by Cui Ying arrived downstairs in Xu You's office.

Arriving at the Fifth Aerospace Academy, Xu You took a short rest and got in touch with Johnson.

Johnson on the other side 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 complete 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 many polite remarks with Johnson and directly pointed out the topic.

"To be honest, we did encounter some troubles. As you know, the recent weather is indeed very unfavorable for rocket launches. This damn weather has forced our launch plan to continue to be postponed."

Xu Youxin said that it was okay to use this excuse on social platforms, but he actually played such a trick on himself.

"Commander Johnson, if that's the case, then I don't think there is any need for us to communicate. I don't have any magical power that can solve weather problems."

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

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

"To be honest, I'm a little disappointed with your performance. This was a problem that could have been solved quickly, but you kept putting it off until I lost interest in helping you solve it."

"Professor Xu You, please understand our difficulties. After all, applying for those confidential documents requires many and complicated procedures. Now that we have completed the application process, we can immediately send the information you need, Professor Xu You.

But we also hope that Professor Xu You can fulfill his promise and help us solve the problem of liquid hydrogen fuel leakage."

"Don't worry, 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 words with you. We have completed the mission of landing on the moon, and those past data are not of any significance to us.

There is nothing of value to learn from.”

Xu You deliberately downplayed the significance of these data, and this is indeed in line with the logic of normal cognition.

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

"Okay, then I will send this information to your email now. The decryption method is still the same as last time. I hope Professor Xu You can use this information to successfully help us solve the problems in the space launch system."

"I have one more condition."

"Professor Xu You, please speak."

"After the spacecraft is successfully launched, Sam Space Agency needs to publicly express its gratitude to us."

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

Johnson pondered for a moment and agreed to Xu You's request.

Soon, Xu You received an email from Sam Space Agency in his mailbox.

After Xu You downloaded the information, he copied the information to another computer that was not connected to the Internet, and used the key to open the attached information.
