Inside the B-class base, a group of system engineers are analyzing the cause of the crash of the "Blue Moon".

Of course, it was not a guess, but through the black box and other storage of the "Blue Moon" to restore the fault situation at that time.

Everyone was very interested in the cause of the accident of the "Blue Moon", and 14 spent half a day with Explorer 9 to dismantle the wreckage of the lander, find other electronic components including the black box, and crack and analyze.

Presumably because NACA didn't think there would be aliens competing for the black box, the information was barely encrypted and was quickly read.

This kind of behavior made Academician She think that it was a little disdainful, and then asked for a copy of the results to be given to the space agency.

A lot of information was still plucked out from Victor and Koch, including the malfunction of the "Blue Moon" before landing and the condition at the time of landing:

In addition, a large-scale subsystem power outage and engine shutdown during landing is definitely an extremely serious accident, but the possibility of a problem at the same time is very low, so it is most likely that a serious failure caused a chain reaction.

Through the lander information sent by NACA, the base checked one by one according to the guidance of the black box, and soon made a discovery.

While Congress was still debating how to get the black box back, the base took the lead in thoroughly understanding the cause of the accident.

"The source of everything is indeed the leakage of this pipeline."

Academician She sat with the experts of the Space Administration who were still at the base, listening to Guo Shen's summary of the accident findings:

"Artemis 2 astronauts said they plugged the leaking valve, but that was really just a solution to the leak, and we think there was a leak somewhere in the connection to the tank.

So why would an empty can that has already leaked cause a serious accident? Then I have to say that in fact, a lot of liquid oxygen has not been leaked and is still in the lander. ”

Guo Shen called up the lander data sent by NACA, and now he has made a cross-sectional view for easy understanding:

"We all know that the purpose of the 'Blue Moon' is to be reusable many times, so they used a double-layer structure inside and outside when designing the personnel cabin, and there are two modules between the part of the personnel living and the lander, which can not only reduce the vibration in use, but also ensure that the personnel cabin is extremely strong, so it is still intact in the forced landing, the air tightness is good, and the hatch can be opened independently."

The experts in the audience all nodded, this design is indeed ingenious, reducing the risk of damage to the interior cabin caused by damage to the exterior of the overall lander.

"The problem is in this compartment, a large part of the leaked liquid oxygen is poured into the compartment, and it took at least a dozen hours to slowly leak out, and we know that there must be quite a lot of wiring harnesses and pipe connections between the inner and outer modules."

Academician She: "You're saying that liquid oxygen destroys these pipelines?" ”

"That's right, because they are inside and sealed, and also to save volume, these pipes are made into integrated plugs, which are not very well protected, and the structure is damaged under the pervasive erosion of liquid oxygen at minus 200 degrees, and it is even worse in the tremor when the engine starts.

So in fact, there is a problem with the connection between these two internal and external modules, which leads to the gradual loss of the internal control ability of the electrical system, except for the specially strengthened manual control part, the electrical system is almost completely destroyed, and the instructions received by the external computer are lost or confused, which leads to problems everywhere. ”

This set of guesses is basically correct with the log, especially explaining why the pressure sensor keeps showing pressure, because the liquid oxygen stored in the compartment after the pipe is blocked is still affecting the sensor and causing misjudgment, and it gradually leaks during the descent process.

So in fact, there are also problems with the installation location of the pressure sensor of the "Blue Moon", there are also problems with the detection of redundancy, and more importantly, it is more important to let the astronauts carry out the mission with problems, which is the root of everything.

On the whole, the technical complexity of the Blue Moon is higher than that of Dawning 3, but the development time is shorter, and it is not mature in itself, and the entire landing mission is also in a hurry, reflecting the changes in the aerospace strength of the entire Aramco.

Academician She overturned the estimate of NACA's strength before the launch of SLS: it turns out that they are already so reluctant.

Although it is fast in China, every procedure is completed step by step, fast but not in a hurry, but this level has made NACA desperate.

Lin Ju: "Do you want to tell them about the fact that we found the black box, without this thing, it will take at least a year for NACA to find out the cause of the accident, and I can't just give up the design of the 'Blue Moon'." ”

Academician She: "Since we all know the information, this can also be used as a bargaining chip, and they have to make more concessions with this thing."

Hey, the majestic NACA at the beginning was also an old man in his twilight years in a blink of an eye, and he committed a lot of aerospace taboos, many of which they were the first to propose. ”

……

"Kazuki Yamamoto, if you continue to carry out dangerous activities like before, we will monitor you and search you from time to time."

The special police officer of the National Police Agency opened the handcuffs to Yamamoto, but the latter was not afraid at all and strode out with his head held high.

Outside, there were more than a dozen people who had been released one after another like him, and they all came to pick up Yamamoto.

"Hey, you can't gather here, get out of here!"

Junji Inoue graciously grabbed Kazuki Yamamoto by the shoulders and got into the car, ignoring the threat of the Police Agency.

"Thank you Yamamoto-kun, only your team was the most vocal in the dozen or so demonstrations we organized, that's why they targeted you like this.

But you see, as I promised, none of you will go to jail. ”

Kazuki Yamamoto: "I'm not afraid of these, I just want to know if our efforts are useful?" ”

"Of course, you see, the weakness of the rice animals has been seen by the whole world, and they almost killed two astronauts.

The power of the Zhongshan parliamentarian is growing, and there is hope that it will soon turn into a stalemate. ”

But then Junji Inoue dispersed his happy expression, and sighed instead:

"But I've only recently learned one thing, and the impact can be very severe."

Seeing this, Yamamoto Kazuki asked, but Junji Inoue was reluctant to say it several times, and only said with a sad face after a long time:

"According to our people at the Edo Electric Power Company, the sewage has actually been secretly discharged two or three times, but it is only on a small scale and has not been detected, and the power company has been instructed by Kishimoto to prepare to forcibly discharge it into the sea."

"Nani?!"

Kazuki Yamamoto clenched his fists angrily: "These bastards will directly bury all our efforts, they all deserve to be punished by God, God!" ”

"Yes, and it's even more shameful that Kishimoto Tsu plans to go to the streets of Chiba Prefecture to give a speech to promote harmlessness, it's really shameful."

Junji Inoue said as he sighed again and slapped his thigh hard:

"It's a pity, it's a pity that the good situation is about to be ruined!"
