Chapter 269 Their layout is too small
After all, it is a country with more than 60 years of development history in the field of aviation technology, and it is the first official cooperation with a private company, which guarantees the safety of this flight mission.

Several astronauts took the Orion spacecraft to the near-moon orbit, and then successfully landed on the predetermined area on the surface of the moon with the help of the lunar module, and successfully completed the astronauts’ out-of-cabin detection mission. Human footprints appeared on the lunar soil again after so many years. The meaning of the representative is also very far-reaching and memorable.

And when the picture of the moon landing was sent back to the ground control center, everyone finally relaxed.

There was a burst of warm applause in the hall.

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

Dali Rover Island.

La Horn Space Force Base.

In the lobby of the control center, after a few days, no tired look could be seen on the faces of the people.

Some are just excited and excited.

Of course, this does not mean that they rest well. After all, they are under such great pressure and need to keep an eye on the situation of the astronauts in the sky, so how can they rest well.

Right now, seeing the astronauts successfully landed on the moon, the intense excitement and excitement temporarily suppressed the fatigue and drowsiness.

Hayden, who also hadn't closed his eyes for a long time, suddenly felt a sense of relief: "It's really great, we have set foot on the moon again."

"Next, the astronauts will complete their tasks and explore resources on the surface of the moon." Ma Sien, who was next to him, did not give up showing his presence at this time, and added: "This is very important for us to build the moon in the future." The base will also help a lot."

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

All previous worries were gone.

"In my opinion, at the current level of technology, it is still more advantageous to develop launch vehicles."

"Now we have easily landed on the moon, and will soon build a permanent moon base. On the other hand, the Yanfang side insists on building a space elevator, and there has been no breakthrough until now."

"It's nothing more than building artificial islands, but what's the use of that?"

The whole person talked with a kind of mood of pointing the country.

Immerse yourself completely in your own world.

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

"Officer Hayden is right. I can't wait to see the scene where the cable of their space elevator breaks." At some point, Ma Sien had two glasses of red wine in his hand, and handed them to Hayden while talking.

next second.

Suddenly, Tripp's figure appeared on the screen.

Looking at the background, they should be sitting in their general office and communicating via video connection.

"Congratulations on completing the mission to the moon."

As Tripp on the screen actively greeted everyone, the sense of honor in the entire command hall became stronger.

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

"Thank you for the concern of the general. It is our duty as astronauts to ensure the smooth progress of the moon landing plan."

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

After the astronauts arrive at the surface of the moon to complete the mission inspection, they still need to take the lunar module to return to the Orion spacecraft in orbit, which also requires the dispatch and cooperation of the ground command center.

The main reason is to return to the moon after a lapse of decades, which is equivalent to getting familiar with the next journey, and does not carry the relevant modules for building a lunar base.

Naturally, it is impossible to stay on the surface of the moon for a long time.

So Tripp ended the call after a few words of concern to the personnel in the space agency.

Didn't take too long.

at the same time.

Washington state symbolizes the highest power palace.

In the office of the general, Tripp looked away from the call device, and he was in a much better mood than some time ago.

At present, their own manned moon landing project is progressing smoothly. As long as the lunar base can be built, more astronauts can be transported 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.

When they have the powerful ability to carry out high-altitude precision strikes against the earth and stars, then there will be no worries.

Even if the development of science and technology in the future is fierce and many miraculous technologies have been created, it still cannot affect their right to speak in the world.

Because the laser weapon that strikes from the moon cannot be intercepted or intervened in advance with the military capabilities on the ground, it is not violated even if it is called a killer.

But to achieve this, the most important point is the failure of Future Technology's space elevator project.

Otherwise, no matter how much it is said, it will be empty talk.

"Future Technology is such a nasty guy, it's just that you're doomed this time."

"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 muttering to himself under the surge of thoughts: "I'd like to see how you guys end up when the cable breaks on the day the space elevator is officially in operation."

Yes.

Ever since Future Technology launched the live broadcast that day, and Hayden came to report the situation to him, he has become more and more convinced that the space elevator looks good now, but sooner or later there will be problems.

The cause of the disease lies in the cable.

He believes that even if future technology can complete the construction of the ground station and the near-Earth spaceport, it will not be able to develop the cables that can maintain the space elevator for a long time.

As long as the cable breaks, not only will the space elevator become a waste product and cannot operate, but it will also cause very large losses. Even the subsequent maintenance costs will be huge, and its cost may not be 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 them.

In all likelihood, the second set of plans he had prepared would not be needed.

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

……

……

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

But in the end, only a few pictures came out.

Can not help but feel a sense of disappointment.

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

Afraid of being seen by others.

Filled with a petty temperament.

Because this moon landing is the first time to return to the moon after many years, major media reported on the eve of the rocket launch, which made the audience's interest ticked up. They want to see the picture of human beings stepping on the moon to satisfy their hearts. the longing for.

In the end, I was dismissed by a few pictures, which will definitely not be satisfactory.

I always feel like I've been cheated.

This situation is like shopping online and buying an item that looks very good, but the difference between the two is very large after the actual receipt.

Especially when everyone came to the space agency and Ma Sien's platform account to request to release more pictures of the moon landing, they were rejected by the officials on the grounds of preventing the leakage of core secrets.

It made everyone's emotions mobilized again, but this time it was negative.

Because in the audience's perception, the so-called core technology will not be leaked because of a simple picture of the moon's surface, not to mention that if the technology is sufficiently advanced, even if the design drawings are taken out, others will not be able to reproduce them.

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

I think that since the future technology can start live broadcasting [-]/[-], it should not be too stingy when it really reaches the moon, and will post related videos no matter what.

Although many of them have belittled the space elevator before, threatening that this kind of project cannot be realized at all, but this does not affect leaving an idea, after all, what if it succeeds.

And this series of reactions from overseas audiences was not lightly ridiculed by domestic netizens.

At the same time, everyone is pinning their hopes on the space elevator.

I look forward to the real success of the space elevator and slap overseas aerospace technology in the face.

Almost a few days after Ma Sien and the others announced the pictures of the moon landing, relevant comments from netizens can be seen on all domestic website platforms with active users.

"He is a fairy, I was looking forward to this overseas moon landing. Although it has nothing to do with us, who made me have a special feeling for the moon in my bones, so I just let me see a few pictures The picture of the footprints, this shit is too stupid."

"Whoever says no can only say that their layout is too small."

"If we want to see the moon landing, we still rely on us to do it ourselves. As long as the space elevator of future technology is built, the moon landing is a casual thing."

"Looking at the arrogance overseas in the past two days is almost driving me mad. I hope Mr. Xu will quickly get out the space elevator and beat them hard."

"Future technology must be supported."

"Don't worry everyone, those people on the extranet are also waiting for our space elevator to be completed quickly."

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

……

Let's talk about Xu Lei's side.

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

Even the pictures of the moon landing they released to the outside world were sent out by Xingtong who actively reminded them.

But what is interesting is that Xu Lei is not surprised by this matter.

It is indeed something that will be done overseas.

In the end, Xu Lei shook his head in the face of these pictures of footprints, and then focused his energy on the experiment.

During this period of time, the remaining synthetic solutions after Xingtong's screening were basically tried, but unfortunately, none of the synthesized materials met the test requirements.

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

Xu Lei is definitely not a compromise or compromise.

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 to continue the rest of the synthesis plan and synthesize a new carbon nanotube material for testing.

Anyway, for him who has all the technical knowledge in his mind, he will definitely be able to find the most suitable materials.

All the efforts right now are just to improve the progress.

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

The space agency has successfully launched the first near-Earth spaceport cornerstone module.

Obviously he proposed the space elevator project, and now other people are progressing faster than him. If the materials for making the cables are not produced quickly, Xu Lei himself will feel a little ashamed.

"Dean, the latest material has been synthesized."

Binjiang City.

Longhu Hi-Tech Park.

At a certain location in the staff restaurant of the headquarters building, Xu Lei connected to a video call from Gu Sanlin, put down the chopsticks in his hand temporarily, and responded: "I'll go there right away, and I will conduct a detailed test of the materials later."

The voice just fell.

Then he ended the call and hurriedly got 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 newly 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 the test, they will need to design a new carbon nanotube synthesis plan. Even with the help of Xingtong and Longhu's light quantum computer, it will still take a long time.

In this case, from the bottom of his heart, Xu Lei hopes that the test will be successful today.

In this way, it is also good to seize the time to manufacture the cable.

Of course, it is often because the theory cannot be 100% achieved in reality, which leads to the final data still needing to be tested, so at this moment Xu Lei is not sure what the result will be.

Soon.

When Xu Lei arrived at the laboratory, he saw Gu Sanlin and others surrounding the experimental platform, even Xingtong's figure was impressively inside.

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

"At present, A18 carbon nanotubes have been successfully synthesized, and we are waiting for the dean to conduct various numerical tests." Gu Sanlin turned around quickly, without hiding the expectation on his face: "This synthesis process and Compared with the previous times, it was more difficult, and I have a hunch that we will definitely succeed."

After listening to Gu Sanlin's response, Xu Lei did not answer immediately, but controlled his eyes to glance over the other people's figures and landed on the section of material.

Different from the extremely thick cable in the imagination, 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 carry out various experiments on the fiber such as tensile corrosion, chemical electrolysis, etc., to simulate the impact of the cable in various environments.

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

The most important reason why space elevators are superior to traditional launch vehicles is their reusability, which can ensure the efficient delivery of personnel and materials to space at a minimum cost.

If it breaks frequently, it is of no use.

Although it is a very critical moment right now, others including Gu Sanlin are quite nervous, afraid of seeing the result of failure.

But Xu Lei still looked calm.

Sermon without any ups and downs: "Bring the materials and let's go to the testing room."

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

After speaking, the few people picked up the materials and set off to the testing area of ​​the research center.

When it comes to this, it needs to be mentioned that this test room is specially built for testing cable materials.

After all, the cables bear the heavy responsibility of connecting the main structures of the space elevators, and ordinary test rooms cannot carry out such a strong tensile test, so Xingtong had to design and temporarily build such a room.

In addition, the testing process is relatively cumbersome and extremely dangerous, so personnel cannot enter.

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

It may be because of the failures of the previous few times, which brought a little bit of self-confidence to others.

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

"Professor Gu, does this mean we can do it this time?"

"I watched the live broadcast that day, and the construction progress of Dengtian Island has already passed halfway, but there is still no movement on our side."

"Without the cable material, the space elevator is almost dead in name only."

"I'm really looking forward to the A18 carbon nanotubes, maybe this time it will really succeed."

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, and it was normal to be concerned about words.

But I don't know whether it is to ease the atmosphere in the observation room, or to cheer myself up, and then I just listen to Gu Sanlin's vowed speech: "Everyone, don't worry, we will definitely pass the test this time."

After finishing speaking, I didn't forget to ask Xu Lei: "You mean the dean?"

Gu Sanlin's move was nothing more than to use Xu Lei's name to appease the project members present and help them rebuild their confidence, but Xu Lei didn't mean to lie about it.

Still indifferently replied: "Maybe."

For this, Gu Sanlin could only show an awkward but polite smile.

Soon when the test officially started, everyone's attention was immediately attracted, and they checked the condition of the materials inside through the observation window.

In the previous several material tests, there were cases where the tensile test broke at the very beginning.

This is undoubtedly the worst outcome.

They naturally don't want to repeat the same mistakes this time.

Otherwise, the materials for this synthesis plan will be directly rejected.

There is no need to think about the latter at all.

Fortunately, the performance of A18 carbon nanotubes did not disappoint everyone. Under the simulated strong tension, the material did not break or have cracks on the surface, and did not even deform.

And pulling several times in a row is the same performance.

This shows that A18 carbon nanotubes have excellent properties as space elevator cables.

Even if other tests are needed in the future, this does not affect the excitement of the project members in the observation room.

"Did you see that the A18 carbon nanotubes passed the test."

"Excellent performance has far exceeded our expectations."

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

Hearing the voices of the people around him, a smile appeared on the corner of Xu Lei's mouth. He had a hunch that the experiment on the synthesis of materials would be officially over.

For the next time, everyone held their breath and looked at the observation window with eager eyes, waiting for the final test results to appear.

However, some tests are carried out in a special closed space, and there is no way for the outside world to observe.

So we can only wait patiently.

I don't know how long ago.

It wasn't until Xingtong standing next to Xu Lei in the observation room opened his mouth that everyone reacted.

"The test is over."

Before anyone else could speak, Xu Lei quickly gave the order.

"Star pupil."

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

"Good boss."

After receiving Xu Lei's order, Xingtong nodded in response, and 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, and has gone through several tests before, so they can naturally see what this data represents.

Almost in an instant, many people's eyes widened and their breathing began to rush.

The whole person is extremely excited.

"This data is simply too strong, and some even greatly exceed the index we made."

"Unbelievable!"

"I knew we'd make it this time, and based on this test result alone we could start working on the cable right away."

"With the dean here, the materials can not give face."

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

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

At least in this way, there is no need to redesign the synthesis scheme of materials.

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

Thinking of this, Xu Lei didn't hesitate, and immediately told Gu Sanlin beside him: "Make a few more pieces of 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 the importance attached to the space elevator project, Xu Lei did not directly manufacture the cables, but instead arranged for Gu Sanlin to conduct new tests many times.

Since Gu Sanlin and Xu Lei have jointly carried out so many projects, they are naturally very clear about his intentions. After hearing this sentence, they quickly assured him: "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 without procrastination in the field he likes.

After receiving Xu Lei's task, he synthesized several new A18 carbon nanotubes on the same day and retested them.

As for the result, there is no doubt about it. A18 carbon nanotubes passed the test without any pressure. So far, this material has been officially determined to be the core material of the cable.

As Future Technology began to manufacture the cables for the space elevator, its project progress has taken another big step forward.

There are still about six months left before the promised space elevator runs. To manufacture a cable with a length of [-] kilometers, Xu Lei doesn't think there is any problem with the strong foundation of future technology. On the contrary, it is more than enough.
