"I believe Mr. Xu will not send us away with photos when the time comes. We look forward to the day when our astronauts land on the moon."

…

Let’s talk about Xu Lei.

From the announcement to the end of overseas moon landing plans, Xu Lei did not pay too much attention.

Even the pictures of the moon landing they released to the public were posted by Star Child on their own initiative.

But what's interesting is that Xu Lei doesn't feel strange about this matter.

It is indeed something that would be done overseas.

Finally faced with these pictures that contained footprints, Xu Lei shook his head and focused his energy on the experiment.

During this period of time, basically all the remaining synthetic solutions screened by Xingtong were tried, but unfortunately, none of the synthesized materials met the testing requirements.

If this material is used to make a space elevator cable with a length of 40,000 kilometers, it will easily break in the middle area, and the space elevator will lose its advantage.

Xu Lei is definitely not a person who settles or makes compromises.

As long as the material does not meet the final test results, it will not be used for the production of cables.

So in this case, he had no choice but to cooperate with Gu Sanlin and continue to implement the remaining synthesis plan to synthesize a new carbon nanotube material for testing.

Anyway, with all the technical knowledge in his mind, he can definitely find the most suitable material.

All efforts at the moment are just to improve progress.

The Dengtian Island ground station has begun to take shape. Under the supervision of Liu Gaowen, the height of the tower continues to rise, and it is about to reach the predetermined tower height.

The space agency has successfully launched the first cornerstone module of a near-Earth space port.

It was obviously him who proposed the space elevator project, but others were making faster progress than him. If he didn't quickly come up with the materials to make the cables, Xu Lei himself would feel a little embarrassed.

"Dean, the latest materials have been synthesized."

Binjiang City.

Longhu High-tech Park.

In a certain location in the employee cafeteria of the headquarters building, Xu Lei answered the video call from Gu Sanlin, and while temporarily putting down the tachyon in his hand, he responded: "I will go over immediately and conduct detailed testing of the materials later."

The words just fell.

Then he ended the call and hurriedly stood up to return to the laboratory.

From the official start of the synthesis experiment of cable materials to now, they have rejected several synthesis plans, and the latest synthesized material mentioned by Gu Sanlin just now is the last one.

So much so that the entire project team paid more attention to it.

If they still fail to pass the test, they will need to design a new carbon nanotube synthesis method. Even with the help of Xingtong and Longfor Light quantum computers, it will still be delayed for a long time.

Under this circumstance, Xu Lei hoped from the bottom of his heart that the test would be successful today.

This will also help you seize the time to manufacture the cable.

Of course, because the theory cannot be achieved 100% in practice, the final data still needs to be tested before it can be obtained. So at this moment, Xu Lei can't guarantee what the result will be. He can only say that he hopes the goddess of luck can take care of it.

Not long after.

As Xu Lei arrived at the laboratory, he saw Gu Sanlin and others gathered around the experimental table, and even Xingtong was prominently among them.

"How is the situation?" Xu Lei walked over and asked.

"At present, the a18 carbon nanotubes have been successfully synthesized, and we are waiting for you, Dean, to conduct various numerical tests." Gu Sanlin quickly turned around, not hiding the expectation on his face: "This synthesis process and

It is more difficult than the previous times, and I have a feeling that we will definitely succeed."

After hearing Gu Sanlin's response, Xu Lei did not answer immediately, but controlled his gaze to pass by the other people and land on the piece of material.

Different from the extremely thick cables as imagined, this piece of material is only as thick as a thumb.

It is equivalent to one of the thousands of fibers in the cable.

The so-called test is to conduct various experiments on this fiber, such as tension, corrosion, chemical electrolysis, etc., to simulate the effects of the cable in various environments.

Only in this way can we ensure that the cable can be used for a long time without frequent breakage.

The most important reason why the space elevator is superior to traditional launch vehicles is its reusability, which can ensure the efficient transportation of personnel and materials to space at the lowest cost.

If it breaks frequently, what use is the hair?

Although this is a very critical moment, everyone else, including Gu Sanlin, is very nervous and afraid of seeing the result of failure.

But Xu Lei still looked calm.

He said without any fluctuation in his tone: "Bring the materials and let's go to the testing room."

"It's the dean." Gu Sanlin nodded immediately.

After saying this, they picked up the materials and headed to the testing area of ​​the research center.

Speaking of this, it needs to be mentioned that this testing room is specially built for testing cable materials.

After all, the cables bear the important task of connecting the main structures of each space elevator. Ordinary test rooms cannot carry out such a powerful tensile test. Therefore, they had to let Xingtong design and temporarily build such a room.

In addition, the testing process is relatively cumbersome and full of extremely high risks, so personnel cannot enter.

After handing the materials to the special robot in the room, Xu Lei, Gu Sanlin and the others went to the observation room next to them to check the final results of the materials.

Maybe it’s because of the previous failures, which gave others a little bit of a lack of self-confidence.

Being in this environment, I couldn't help but start to worry.

"Professor Gu, do you think we can make it this time?"

"I was watching the live broadcast that day. The construction progress of Dentian Island was already over halfway, but there was no movement on our side yet."

“If we can’t produce the cable material, the space elevator will just exist in name only.”

"I'm really looking forward to a18 carbon nanotubes. Maybe they will be successful this time."

Gu Sanlin listened to the discussion of the people below and understood that everyone was also thinking about the space elevator and hoped that this super project would really succeed. It was normal to be worried in words.

But I don't know whether it was to ease the atmosphere in the observation room or to cheer myself up. Then I just listened to Gu Sanlin's vowed sermon: "Don't worry, everyone, we will definitely pass the test this time."

After saying that, he didn't forget to ask Xu Lei: "You think so, Dean?"

Gu Sanlin's move was simply to use Xu Lei's name to appease the project members present and help them regain their confidence. However, Xu Lei had no intention of lying because of this.

Still looking indifferent, he replied: "Maybe."

In response, Gu Sanlin could only show an awkward but polite smile.

Soon when the test officially started, everyone's attention was immediately drawn to it, and they looked through the observation window to determine the condition of the materials inside.

In previous material tests, there were cases where the material broke just after the tensile test started.

This is undoubtedly the worst result.

Naturally, they don't want to make the same mistake again this time.

Otherwise, this time the synthetic materials will be directly rejected.

There is no need to think about what happens next.

Fortunately, the performance of a18 carbon nanotubes did not disappoint everyone. Under the simulated strong tensile force, the material did not break or have cracks on the surface, or even deform.

And pulling it several times in a row still shows the same behavior.

This shows that a18 carbon nanotubes have excellent performance as space elevator cables.

Even if other tests need to be carried out next, this does not affect the excitement of the project members in the observation room.

"Did you see that a18 carbon nanotubes passed the test?"

"The performance is outstanding and has far exceeded our expectations."

"I'm afraid we've already developed the material for the cable."

Hearing the voices of the people around him, a smile suddenly appeared on Xu Lei's lips. He had a hunch that the material synthesis experiment was about to officially end.

In the following time, everyone could be said to be holding their breath and looking at the observation window with eyes filled with desire, waiting for the final test results to appear.

However, some tests are conducted in special closed spaces and cannot be observed by the outside world.

So we can only wait patiently.

I don’t know how much time has passed.

It wasn't until Xingtong, who was standing next to Xu Lei in the observation room, spoke that everyone reacted.

"Testing has ended."

Xu Lei quickly issued the order before anyone else could speak.

"Starboy."

"Get the test data of a18 carbon nanotubes."

"Okay boss."

After receiving Xu Lei's order and Xingtong nodded in response, within a few seconds, a holographic projection screen appeared in front of everyone, with the official test results of various data integrated on it.
To be continued...
