The construction of the first phase of the framework of Xinggang has been completed.

The rest of the internal equipment installation will be completed in less than a year.

"The 3.5-meter aperture space-based optical telescope has preliminarily completed the research and development work, and the people of the Institute of Optics and Mechanics are preparing to overcome the difficulties in manufacturing."

The secretary looked at the various notes in the notebook and reported to Zhang Xingyang.

"There should be a lot of technical difficulties in the manufacture of space-based optical telescopes."

Zhang Xingyang looked up from the mountain-high pile of papers.

With a bright gaze, he said:

"You don't need to push them in particular, as long as you can do it in five years, you'll be fine."

Large-aperture space-based telescopes for observations of deep space in the universe.

Before that, the most famous was the Hubble telescope.

In terms of large-aperture optical telescopes, the technical strength of China is relatively weak.

So Zhang Xingyang also gave them enough time to carry out research and development work.

The difficulties of large-aperture optical telescopes are mainly concentrated in the large size of the mirror.

The 3.5-meter mirror takes at least two years to be carefully polished.

"Aside from this, is there anything else I need to focus on lately?"

Zhang Xingyang rubbed his eyes and asked.

His health is much better than that of the average scientific researcher, but he is in a state of saturation for a long time.

I also feel tired from time to time.

"The large model of the electromagnetic acceleration device for the transportation of materials on the lunar surface will officially start construction next week."

"They want you to check it out."

The secretary hurriedly flipped through the notebook and said.

The design of the electromagnetic acceleration device is simple, and it is not complicated to build.

It is basically the same principle as electromagnetic weapons.

There are also several different structures.

At present, the simplest structure of coil electromagnetic acceleration device is used in China.

Prior to this, factors restricting the development of electromagnetic weapons and electromagnetic devices.

The main thing is the energy issue.

Conventional gas turbines, steam turbines, etc., are difficult to generate extremely strong currents in an instant.

And the hydrogen-oxygen explosion engine, although it is able to produce a stronger current.

However, the sustained output time is very short.

It is only suitable for laser weapons, which require short-term high-output weapons.

After the thorium-based molten salt reactor was overcome.

In fact, domestic electromagnetic weapons already have excellent conditions for development.

The construction of the large model of electromagnetic acceleration orbit is based on this situation.

Although the core energy problem is solved.

However, the electromagnetic acceleration track itself still has a lot of technical difficulties that need to be tackled.

For example, segmented track alignment technology.

Space is not like the ground, where it loses the shackles of Earth's gravity.

The slightest disturbance can cause the orbit to deviate.

And after the orbital deviation.

An accelerating object that is in the center of the accelerator cylinder.

Deflection will occur.

Finally, it directly penetrates the thin metal wall of the accelerator cylinder.

"What time is it?"

Zhang Xingyang opened his work notebook and asked.

"Nine o'clock in the morning next Tuesday."

The secretary replied, "At that time, Mr. Ouyang Yuan, the chief engineer of the moon landing program, also wants to talk to you. ”

The domestic moon landing program actually started very late.

Because the breakthrough in manned space technology was late.

In fact, it was in China until the establishment of the Chang'e Project.

It was clearly proposed to send astronauts to the moon.

Among them, Zhang Xingyang's opinion played an extremely important role.

In the past few years, the dragon kingdom made a lunar probe - Yutu.

It has traveled more than 50 kilometers on the lunar surface and explored a large area that has never been explored by a probe.

And a year ago, Chang'e-5 achieved the first sample return.

Kilograms of abundant lunar rock samples were collected from the lunar surface.

Some of them came from dust from the craters.

Some are drill cores.

The construction site of the electromagnetic acceleration orbit model was set in a small city in the East China Plain.

It is far away from the major earthquake zones in the country.

The last recorded earthquake was even 80 years ago.

"Dean Zhang, long time no see."

At the start of construction, Ouyang Yuan, who had a ruddy face, greeted Zhang Xingyang and said.

"Long time no see."

Zhang Xingyang took the initiative to stretch out his hand and shake hands with the other party.

The two met a long time ago when the Chang'e project was just established.

At that time, Zhang Xingyang was in charge of research on heavy rockets and lunar landers.

As a scholar of planetary geology, Ouyang Yuan has dealt with Zhang Xingyang several times.

"I've been seeing you in the media lately, haha."

Ouyang Yuan laughed a few times and said.

"Especially since the completion of the infrastructure construction of Starport, both at home and abroad, there has been a wide range of discussions about its significance to human beings."

The success of the construction of the Star Port has greatly enhanced the self-confidence of the people.

It represents that the era of the second or third scientific and technological powers occupying space in the past is already a thing of the past.

Next up is the space age of late-developing countries led by the Dragon Kingdom.

"It's all about everyone's joint efforts, and I've only done some insignificant work."

Zhang Xingyang said modestly.

Of course, he wasn't lying.

If it weren't for the thousands of workers from all walks of life who have worked hard for the construction of Xinggang in China.

Relying on Zhang Xingyang alone, he would not be able to build such a space miracle under any circumstances.

If he is not in this country, but in other countries.

Even in more technologically advanced countries, such a miracle building cannot be completed

This is a space miracle that belongs to the Dragon Kingdom.

It is also a space miracle that belongs to all the people.

"What do you think about the manned lunar landing program?"

After a few words of greeting, Ouyang Yuan asked.

This is also an important reason why he rushed over this time to meet Zhang Xingyang.

That is, on the issue of landing on the moon, he received Zhang Xingyang's full support.

At present, there are two ideas about the moon landing in China.

The first is that our technological and economic level is already capable of supporting us to carry out a manned landing on the moon.

The second is to hold the opposite view.

"I think we only have the capacity to put a small number of people on the moon for a short period of time."

Zhang Xingyang looked at the land that was still a plain in the distance.

On the winter plain, there are patches of green winter wheat.

These weed-like crops, after a cold winter.

Eventually, the spring and summer will be full of growth.

"If you want to carry out scientific research, exploration and other work on the lunar surface on a large scale, it will take a certain amount of time."

"In particular, we need to wait until the construction of a small electromagnetic acceleration device is completed."

Zhang Xingyang withdrew his gaze from the distance and fell back on Ouyang Yuan.

Zhang Xingyang's idea is more from a practical point of view.

If only a small number of astronauts are sent to the moon for a short period of time.

Instead of really carrying out large-scale scientific research and development work on the lunar surface.

Then there is no point in wasting a lot of money.

It is no longer the era of the Cold War, when Maozi and Hawk-chan competed for the title of the moon landing.

A mere moon landing has little meaning other than fame.

"But before a large-scale moon landing, we need to use a small-scale moon landing to verify the technologies needed for the moon landing."

Ouyang Yuan and Zhang Xingyang stood side by side and said.

"If it does not go through rigorous technical verification, it will directly carry out a large-scale moon landing activity."

"That would lead to a series of disasters."

Since Ouyang Yuan prefers to start a small-scale moon landing activity first, he naturally has his reasons.

The most important reason is to carry out technical verification of the lunar spacecraft.

It's like manned spaceflight, which didn't start with the fact that six people are in orbit at the same time.

At the beginning, it also experienced a transformation from an unmanned experimental spacecraft to a single-person short-duration spacecraft, and then to a multi-person multi-day in-orbit flight.

This is also true for manned spaceflight, which is a little less difficult.

The more difficult manned landing on the moon requires rigorous technical verification.

"Do you have a plan for the moon landing?"

Zhang Xingyang did not continue to struggle with Ouyang Yuan in this regard, but asked another question.

Ouyang Yuan said: "Before the large-scale construction of Xinggang was achieved, we were actually more inclined to adopt the scheme of direct landing on the moon. ”

The direct moon landing program is a program that Eagle Sauce used decades ago.

And they really landed on the moon with such a scheme.

Therefore, the people who crossed the river by touching the eagle sauce naturally chose this way of landing on the moon.

"And now?"

Since it is said that it was before, then it is said that after the completion of the construction of Star Port.

They have changed their minds.

"Now we are more inclined to launch astronauts, lunar spacecraft, and landing capsules."

"Launch them into the starport in batches, and then complete the assembly work inside the starport."

"Then fly to the moon from the geosynchronous orbit where the starport is located."

Ouyang Yuan explained why they had such a change in thinking.

"In fact, the supplies that astronauts can carry are very limited, and the danger is greater."

"So, both in terms of security, but also in terms of success rates."

"In the end, we all agreed that the orbital assembly plan was more suitable for us than the direct moon landing plan."

The world is not static.

It is in a dynamic development.

Decades ago, Eagle Sauce did not have the conditions that the Dragon Kingdom has today.

So they can only use the stupid method of flying bricks.

Adopt a method that does not count the cost of construction to build a lunar rocket with super thrust.

Then the astronauts, supplies, lunar rover, etc., all stuffed into the rocket.

A one-time launch did help a lot to improve the success rate at that time.

But today, the astronauts of the Dragon Kingdom have a better choice.

Naturally, there is no need for astronauts to continue to take great risks and fly to the moon with other things.

After listening to this, Zhang Xingyang suddenly asked, "Have you ever understood the spaceship interface design of Starport?" ”

The name of the star port has a Hong Kong character in it.

Prove that it's not just a super-large space station.

It is also a port within space, between the stars.

Then if the spaceship wants to dock in the starport, it naturally has to meet its conditions.

"I haven't understood." Ouyang Yuan shook his head and said.

The specific technical indicators of Xinggang, in addition to the technical personnel who are actually involved in it.

There are very few details that the outside world can know.

Most people only know part of it.

"The first phase of the construction of Xinggang is not huge, and the diameter is only 900 meters."

Zhang Xingyang said with a bit of Versailles.

"The number of spaceships that can dock is also limited."

"But it's just over two hundred."

When Ouyang Yuan heard "There are only more than two hundred ships", he felt that a mouthful of old blood was about to spurt out of his throat.

Looking at Ouyang Yuan's strange expression.

Zhang Xingyang sighed and said, "Maybe this is already an extremely large number in your opinion. ”

"But for Starport, none of that is enough."

"The first phase of Xinggang will be able to accommodate 1,000 astronauts."

"These ships are barely enough to supply them with all the supplies they need to live."

The amount of supplies a person needs every day is a very large number.

Especially if both air and water need to be transported from the ground.

"And more than 200 spaceships must use the same interface to be able to connect with the starport."

Zhang Xingyang said seriously: "Otherwise, the materials on it can only rely on the most primitive manpower to carry them." ”

Only after the spaceship is connected to the starport can it borrow the automation equipment inside the starport to quickly load and unload various materials.

"So our moon spacecraft and material spacecraft must also use the same specification interface?"

Ouyang Yuan asked, "Doesn't this mean that there will only be one interface standard in space in the future?" ”

Zhang Xingyang's words reminded Ouyang Yuan of more in-depth content.

That's the question of the overall standard of the future spacecraft.

Now that the star port has been mastered, China has the confidence to set standards for future spaceships.

And all this Zhang Xingyang said means that the construction of spaceships will not be carried out in accordance with the standards of the Dragon Kingdom in the future.

Then you will also lose the right to speak in space.

Once the power to formulate technical standards is in hand, even if the dragon kingdom will fall behind in technology for a short time in the future.

Then there is ample opportunity to re-iterate on the technology.

This is also a valuable legacy that Zhang Xingyang's generation of aerospace workers can leave for future people.

"The groundbreaking ceremony for the large model of the electromagnetic acceleration device is about to begin, let's go."

The groundbreaking ceremony not far away is almost ready.

Zhang Xingyang patted Ouyang Yuan, who was in a state of shock, and said.

Whether it is the successful construction of Starport, or the formulation of technical standards.

For Zhang Xingyang, it's all in the past.

If you want to win more in the future, you will have to develop the moon, the closest extraterrestrial planet to humans.

The electromagnetic acceleration device is an extremely important part of the journey to the moon.

Ouyang Yuan thought about it for a while, and then he followed the nervous Xingyang's pace.

Walk towards the site of the groundbreaking ceremony where the first handful of soil is being shoveled in the distance.

In any case, the dream of the dragon people to go to the moon will be realized in our generation.

The bright red flag will eventually be planted on this planet that has accompanied mankind for tens of millions of years! (End of chapter)
