My science and technology museum

After all, it is a country with more than 60 years of development history in the field of aviation technology. In addition, it is the first official cooperation with a private company, which ensures the safety of this flight mission.

Several astronauts took the Orion spacecraft to reach the near-lunar orbit, and then successfully landed on a predetermined area on the lunar surface with the help of the lunar module, and successfully completed the astronauts' extravehicular exploration mission. After so many years, human footprints appeared on the lunar soil again. The meaning it represents is also very profound and worthy of commemoration.

When the moon landing footage was transmitted back to the ground control center, everyone finally felt relaxed.

There was a burst of warm applause in the hall.

Even General Tripp sent a video call to express his condolences.

Dali Rover Island.

La Jor Space Force Base.

In the control center hall, after a few days, no one showed any signs of fatigue on their faces.

Some are just excited and excited.

Of course, this does not mean that they rest well. After all, they are under so much pressure and need to always pay attention to the astronauts' situation in the sky, so how can they rest well?

At the moment, I just saw the astronauts successfully landed on the moon. The strong excitement and excitement temporarily suppressed the fatigue and sleepiness.

Hayden, who had also not slept for a long time, suddenly felt relieved: "It's so great, we set foot on the moon again."

"Next, the astronauts will complete their missions and explore resources on the lunar surface." Marsen, who was next to him, did not give up showing his presence at this time. He took over the conversation and added: "This will be very important for our subsequent construction of the moon. The base will be a big help as well.”

Perhaps he was temporarily dazzled by the joy in front of him, but suddenly Hayden didn't think the space elevator was that powerful.

All the previous worries were gone.

"I think given the current level of science and technology, it is more advantageous to develop launch vehicles."

"Now that we can easily land on the moon, we will soon build a permanent lunar base. On the other hand, Yanfang insists on building a space elevator, but so far there has been no breakthrough."

"It's just that building artificial islands is more powerful, but what's the use?"

The whole person talked with a feeling of pointing out the country.

Completely immersed in your own world.

At this time, Marsne must follow Hayden's remarks. After all, his space exploration technology company still relies on NASA's lunar base project for development.

"What Chief Hayden said is right. I can't wait to see the scene where their space elevator cable breaks." At some point, Marsen had two glasses of red wine in his hand, and he handed them to Hayden as he spoke.

The next second.

Suddenly, Tripp's figure suddenly appeared on the screen.

Judging from the background, he should be sitting in his office, communicating via video link.

"Congratulations on completing your mission to the moon."

As Tripp on the screen took the initiative to greet everyone, the sense of honor in the entire command hall became stronger.

Hayden and Marsen naturally did not hesitate about this, and immediately expressed their determination.

"Thank you, Commander-in-Chief, for your concern. It is our duty as astronauts to ensure the smooth progress of the moon landing program."

"Soon we will carry out a new launch mission, and will carry the lunar base module to try to build a base for habitation. I believe that the first country to build a permanent base on the moon will definitely be us."

After the astronauts arrive on the lunar surface to complete the mission inspection, they still need to ride the lunar module back to the Orion spacecraft in orbit, which also requires the scheduling and cooperation of the ground command center.

Mainly, this time it is a return to the moon after decades, which is equivalent to getting familiar with the journey, and it does not carry the relevant modules for building a lunar base.

Naturally, it cannot stay on the lunar surface for a long time.

So Tripp ended the call after briefly expressing concern for the personnel within the space agency.

Didn't occupy it for too long.

at the same time.

Washington is the palace that symbolizes the highest power.

In the Consul General's office, Tripp looked away from the phone device and was in a much better mood than before.

At present, our own manned moon landing project is proceeding smoothly. As long as we can complete the construction of the lunar base, we can transport more astronauts to the base to participate in the mining of lunar resources.

Until he completes the most important step in his plan, building a super-large laser weapon.

Once they have the powerful ability to carry out high-altitude precision strikes against Earth and stars, they will no longer have to worry about anything.

Even if science and technology develops rapidly in the future and creates many miraculous technologies, it still cannot affect their right to speak in the world.

Because the laser weapons that attack from the moon cannot be intercepted or intervened in advance by the military capabilities on the ground, it is not wrong to say that they are a trump card.

However, in order to realize these, the most important point is the failure of the future technology space elevator project.

Otherwise, no matter how much you say, it will be empty talk.

"Future Technology is such a nasty guy, but this time you are destined to fail."

"Since the space elevator has been abandoned by the scientific community, it proves that it has problems and cannot be manufactured at all."

Sitting in his seat, Tripp couldn't help but murmur to himself as his thoughts surged: "I want to see how you end up when the cable breaks on the day when the space elevator is officially put into operation."

Yes.

Ever since Future Technology started the live broadcast that day and Hayden came over to report the situation to him, he became more and more convinced that the space elevator might look good now, but sooner or later there would be problems.

The cause of the disease is on this cable.

He believes that even if future technology can complete the construction of ground stations and near-Earth space ports, it will not be able to develop cables that can maintain the long-term operation of space elevators.

As long as the cable is broken, not only will the space elevator become useless and unable to operate, it will also cause very large losses. Even the subsequent maintenance costs will be huge, and its cost is not necessarily cheaper than the launch vehicle.

So in this case, Yan Fang has mastered the space elevator, and I am afraid that the speed of building the moon base will not be as fast as theirs.

In all likelihood, the second plan he prepared will not be used.

For Tripp, he is even looking forward to the future technology of the space elevator being built and put into use as soon as possible. He believes that the scene caused by the cable break will definitely be very spectacular.

…

…

The news of re-landing on the moon is very popular on the Internet, and major media and news magazines have reported on it.

But in the end, only a few pictures were circulated.

Jean couldn't help but feel disappointed.

Based on their technical level, there is absolutely no problem in video recording the astronauts' actions on the lunar surface, but they have to hide it.

Afraid of being seen by others.

Full of a petty temperament.

Because this moon landing was a return to the moon after many years, major media reported it on the eve of the launch of the rocket, which aroused the interest of the audience and wanted to see the scene of humans setting foot on the moon to satisfy their hearts. of that longing.

As a result, I ended up with just a few pictures, which is definitely not satisfying.

I always feel like I've been cheated.

This situation is like buying an item online that looks very good, but after receiving the goods, it turns out to be very different.

Especially when people came to the platform accounts of NASA and Mars to request more footage of the moon landing, they were refused by the officials on the grounds of preventing the leakage of core secrets.

Everyone's emotions were mobilized again, but this time it was negative.

Because in the audience's perception, the so-called core technology will not be leaked through simple lunar surface images. Moreover, if the technology is advanced enough, I am afraid that even if the design drawings are taken out, others will not be able to reproduce it.

As things gradually escalated, many people turned their attention to the space elevator of future technology.

I believe that since future technology can enable 24/7 real-time live broadcast, we will not be too stingy if we actually reach the moon, and will publish relevant videos no matter what.

Although many of them had previously belittled the space elevator and threatened that such a project would be impossible to realize, this did not affect the idea of ​​leaving it behind, after all, what if it succeeded.

This series of reactions from overseas audiences was ridiculed by domestic netizens.

At the same time, everyone is placing more hope on the space elevator.

I hope the space elevator can truly succeed and slap overseas aerospace technology in the face.

Almost within a few days after Marsen and his friends released the moon landing pictures, relevant comments from netizens could be seen on any website platform with active users in China.

"You are a fairy. I was originally looking forward to the overseas moon landing. Although it has nothing to do with us, I have a special feeling for the moon in my heart. But in the end, I was asked to see a few pictures. Pictures of footprints, this is too bad."

"Whoever says otherwise can only say that their structure is too small."

"If we want to see a moon landing, we still have to count on ourselves. As long as the space elevator with future technology is developed, the moon landing will be a casual matter."

"The arrogance overseas I have seen in the past two days almost makes me mad. I hope Mr. Xu will quickly bring out the space elevator and slap them in the face."

“You have to support future technologies.”

"Don't worry, everyone. People on the external network are also waiting for our space elevator to be completed as soon as possible."

"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 the overseas moon landing plan, Xu Lei did not pay too much attention.

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

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

It is indeed something that would be done overseas.

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

During this period of time, basically all the remaining synthesis plans 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 in 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.

At a certain location in the staff restaurant of the headquarters building, Xu Lei answered the video call from Gu Sanlin. He temporarily put down the chopsticks in his hands and 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. 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 this.

If they still fail to pass the test, they will need to design a new carbon nanotube synthesis plan. Even with the help of Xingtong and Longhuzhiguang 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 also makes it easier to 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 hope that 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, including Xingtong's figure.

"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 Dean Qi to conduct various numerical tests." Gu Sanlin quickly turned around, not hiding the expectation on his face: "This synthesis process and It’s more difficult than the previous times, and I have a feeling we will definitely succeed.”

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

Different from the extremely thick cable as expected, 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, the group 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 heavy responsibility 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 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 Dengtian Island was already over halfway, but there was no movement on our side yet."

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

"I'm really looking forward to A18 carbon nanotubes. Maybe this time it will be successful."

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 succeed. It was normal to be worried in words.

But he didn't know whether he wanted to ease the atmosphere in the observation room or to cheer himself up. Then he just listened to Gu Sanlin's vow: "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 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 outcome.

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

Otherwise, the materials for this synthesis plan 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 pulling force, the material did not break or have cracks on the surface, or even deform.

And pulling it several times in a row has the same performance.

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 was outstanding and 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 staring at the observation window with eager eyes, 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 Xing Tong, who was standing next to Xu Lei in the observation room, spoke that everyone reacted.

"The test is over."

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

"Xingpu."

"Bring out the test data of A18 carbon nanotubes."

"Okay boss."

After receiving Xu Lei's order, 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.

Everyone here is a top scientist in the field of materials. They have gone through several tests before, so they can naturally see what this data represents.

Almost instantly, many people's eyes widened and their breathing began to quicken.

The whole person was in a state of extreme excitement.

"This data is simply too strong, and some even exceed the index we established by a large margin."

"Incredible!"

"I knew we could succeed this time. Based on this test result alone, we can start making the cable immediately."

"With the dean here, I can't give you face with the materials."

As everyone said, the test data of A18 carbon nanotubes far exceeded expectations and fully complied with the requirements of space elevator cables.

Although Xu Lei had already expected it, there was a lot of joy in his heart at this moment.

At least this way there is no need to redesign the material synthesis scheme.

This can be regarded as saving a lot of time for the entire space elevator project.

Thinking of this, Xu Lei did not hesitate, and immediately told Gu Sanlin beside him: "Make a few more A18 carbon nanotubes, and then test them separately. If the results are still the same, then start construction." The manufacture of cables."

Adhering to the scientific rigor and emphasis on the space elevator project, Xu Lei did not directly manufacture the cables. Instead, he arranged for Gu Sanlin to conduct new tests many times.

Gu Sanlin and Xu Lei have worked on so many projects together, so they naturally know his intentions very well. After hearing this sentence, he quickly assured: "Don't worry, Dean, I guarantee that there will be no problems with the A18 carbon nanotubes."

You must know that Gu Sanlin has always done things vigorously and resolutely without delay in the field he likes.

After receiving the task from Xu Lei, several new A18 carbon nanotubes were synthesized that day and tested again.

As for the result, there is no doubt that the A18 carbon nanotube passed the test without any pressure. At this point, this material has been officially determined to become the core material of the cable.

As Future Technology begins to manufacture the cables for the space elevator, its project progress has once again taken a big step forward.

There are still about six months left before the previously promised operation time of the space elevator. It is necessary to create a cable with a length of 40,000 kilometers. With the strong foundation of future technology, Xu Lei does not think there is any problem. On the contrary, it is more than enough.
