This is how black technology should be used

Chapter 275: Future Amusement Park Space Station
If the audience just looked at the renderings and thought the new space station was huge and surprised, then they would be speechless after Mr. Yang finished his introduction.

If it is normal to add a parking module, then the two "big wheels" at the back start to run wildly at a fork in the road.

Some viewers guessed the purpose of the "big wheel", but after Mr. Yang's personal confirmation, that is another matter.

Simulated gravity, this is really something in the realm of science fiction.

Whether it is the "far future" anti-gravity simulation of gravity or the "near future" rotation simulation of gravity, they are all things that can only be seen in science fiction works.

Although there are similar research plans in the history of spaceflight, but because they have never been implemented, and have been carried by science fiction works as the material setting, then it is science fiction!

And today, science fiction is about to come true!
Even if it's not 100% Earth's gravity, it's only about the same level as Mars' gravity, but it's about the same.

That's a great start, isn't it?

And the "industrial zone" behind it will surprise the audience even more.

Human manufacturing has developed rapidly, but due to the natural physical environment of the earth, many materials and manufacturing methods have encountered bottlenecks.

But in the space environment, there are many new breakthroughs in the preparation and manufacturing methods of materials.

Human beings use the zero-gravity and high-vacuum space environment to produce high-quality large-scale single crystals urgently needed on the earth, high-strength composite materials for rockets and aerospace vehicles, high-grade glass for optical instruments, high-temperature resistant metal materials for atomic reactors, and high-purity medicines, etc. .

Such as interferon.

More than 20 years ago, the Commonwealth of Liberty was produced from biological cells using genetic engineering technology. The purity was very low, because it had to be separated from a mixture of more than 100 other biological cell products, and the operation had to be very careful and the speed was very slow.

Otherwise, the mixture in the solution will easily rise or sink.

In space, since there is no gravity, this problem does not arise.

Scientists believe that interferon produced in space is 100 to 400 times purer than that produced on earth.

Space experiments have also been used to show that single crystals produced in orbit can be 10 times larger than those on the ground!
Under zero-gravity conditions, the lattice of the crystal is arranged neatly, and the crystal grows uniformly, which greatly improves the integrity of the crystal. The use of container-free suspension growth can also avoid container pollution, and high-purity crystals can be obtained.

With this large, high-quality single crystal, a subsystem, such as a memory system, can be implemented on a single crystal.

Or a computer made into a single-chip crystal is conducive to improving the reliability, storage capacity and computing speed of the computer.

Moreover, large high-quality single crystals are used in solid-state lasers, which can greatly increase the power.

There is also a special optical fiber called "ultra-pure fluoride", which has higher infrared transmission than silicon and is mainly used in high-end lasers, optical fiber cables, medical products and other fields.

The traditional method of producing the material, in Earth's gravity, melts it at high temperatures and then stretches it into shape by letting it drop from a height.

But the problem is that the different components contained in this material have different densities, so the material forms microcrystals during the cooling process, which affects the application of the material in fields such as communications.

Moreover, the material is relatively "fragile", the effect is not satisfactory, and the price is very expensive, so it has not yet been put into the commercial market.

But manufacturing in space is different. In the vast space of space, larger glass blocks can be used to easily pull out thousands of meters of optical fiber.

On the other hand, without the influence of gravity, precipitation or crystallization does not easily occur in the fiber.

From the perspective of the finished product, the optical fiber made in space is longer and the interior is clearer, and the communication quality and effect will be greatly improved.

This is only an advantage in materials. When the advantages of various materials are combined, humans can directly produce spacecraft in space.

Take satellites, for example.

All current spacecraft are manufactured on Earth, installed in the fairing of the rocket head, and finally launched into orbit.

In this way, from the manufacturing to the launch process, the volume and structure of the satellite are greatly limited by the small space of the rocket head.

In order to fit the satellite into the cylindrical space of the rocket head with a diameter of about 2 to 5 meters, most of the existing satellites are made into a "fat box + folded wings" structural design.

However, this single structure of "fat box + folded wings" is not the best geometric structure for satellites to perform tasks in many cases.

For example, the antennas used in some remote sensing and communication satellites often require a huge spatial extension.

And this huge mechanical structure must be folded in the narrow rocket head, which will bring great inconvenience technically.

In fact, space engineers have designed many satellites with imaginative and more powerful geometric structures, but they were "aborted" because they could not be folded into the rocket.

Producing satellites in the "space factory" frees the geometry of the satellite from the shackles of launch.

Due to the empty microgravity environment of the space orbit, the structure of the satellite can be arbitrary in theory.

Even a "space factory" can slowly build a spacecraft in space that is much larger and more complex than itself, like ants building a nest, which will greatly liberate the design imagination of space engineers.

Then it is possible to make lower reliability requirements for satellite structures.

The working environment of satellites in space is vacuum + microgravity, which means that different parts will not squeeze each other due to gravity.

Only in this sense, the mechanical structure of the satellite does not need to be "strong" again.

Since the satellite has to withstand the impact of 10 to 20 times the acceleration of gravity during the rocket launch process, in order to withstand this strong impact, the satellite must be particularly "strong" from the whole to the parts.

Therefore, until today, both the overall structure of the satellite and the components on it must undergo the most rigorous mechanical shock and vibration tests before launch to ensure that the overall structure can withstand the harsh shock + vibration environment of a "car accident". intact.

Such high requirements for reliability make the components used in satellites often have to go through thousands of selections, which are very expensive and increase the overall cost.

At the same time, many structural solutions that have obvious performance advantages but are not very strong cannot be finally adopted.

These troubles can be avoided by directly manufacturing satellites in space.

For example, polymer powder can be packaged and launched into space, and then the mechanical structure frame of the satellite can be printed out by 3D printing equipment in space.

The satellite design can also be modularized to provide agile satellite repair capabilities.

The so-called modular design concept is to split the satellite into several standardized functional modules, just like the camera module, battery module, antenna module and so on in the mobile phone.

Each module can be produced independently, and can be assembled into a complete satellite at any time like building blocks.

A very huge benefit of this is that satellites in space can be repaired quickly and at low cost.

Many satellites today are often scrapped due to local minor faults such as power module wear or antenna damage.

If replacement functional modules can be quickly and independently produced in space, and then replaced by new modules by space maintenance robots, the service life of satellites in space can be greatly improved, the speed of maintenance can be improved, and the maintenance cost of the entire satellite system can be reduced. .

And there is no need to worry about manufacturing resources, not to mention that the scrapped space junk can be recycled, and the resources in space itself are extremely rich.

According to the current discovery situation of the International Science Corps of Science and Technology, there are several valuable asteroids passing around the earth, which can be called "flying treasure chests".

There is a so-called M-type asteroid. Most of the components of this star are metals, and its main components are iron and nickel, which are widely used metals on the earth.

Then there is an asteroid named UW-158, whose basic composition is gold and is worth trillions of federal coins.

There is also a giant cosmic diamond called BPM-37093, which is the crystallization of a white dwarf star, which is basically a 4000-meter-long diamond.

The most outstanding one is a planet called 16-Psyche by scientists, which contains a large amount of gold and platinum, and its current market value is 10 trillion federal coins.

Of course, these things are too big to be moved by the second-phase space station, but at least the second-phase space station has allowed many people to see the future.

"Good guy, this space station is too awesome!"

"This space station is too big. The individual cabins of the first phase are larger than the individual cabins of the International Space Station. Now there are individual cabins with a diameter of 18 meters. This is too fierce!"

"The rotating simulated gravity cabin is amazing. Humans have finally developed the technology to simulate gravity."

"Surprised, it turns out that the space station can do so many things!"

"Then is this still a space station? It feels like a space city?"

"It's too early to talk about a space city. How can there be a space city with a scale of 300 meters?"

"But in terms of configuration, it's too different from the previous space station."

"Actually, it's almost the same. The second phase of the space station still focuses on scientific research and experiments. Even the 'industrial zone' is not open to work, and most of them are still in the nature of testing."

"Let's not talk about the city or the city, you can say that the length is 300 meters, the 'wingspan' of the solar panels is 400 meters, plus the thick cabin, the mass exceeds 1500 tons, and the internal pressurized space has reached an astonishing 5 cubic meters. Is the second phase of Mi's project big?"

"Big! Too big!"

"The pressurized space of the International Space Station is less than 1 cubic meters. You tell me this is 5 cubic meters?"

"Yes, although it is only 300 meters, but the 110 meters of water that cannot support the International Space Station is too large. In fact, the solar array and large trusses are removed, and the main body of the pressurized cabin of the International Space Station is not too large."

"Well, the second phase of the Starry Space Station is different. They have so many huge cabins with a diameter of more than ten meters, and there are rotating cabins. The space should be large."

"If it is built, it will definitely be the largest space station in the world!"

"This is not a space station, this is a space wonder!"

"Humans really like to build wonders!"

People were discussing these things in shock, and then they saw Chief Master Yang step down and Li Future came up.

The change of one old and one young even caused the netizens to be shocked and dumbfounded.

Chief Master Yang has already said earlier that the second phase of the Starry Space Station project is a collaboration between the Space Administration and Practical Science and Technology Group. The space station has done preliminary experiments on "space manufacturing", such as 3D printing, and space maintenance and assembly. Astronauts do it, the current "industrial zone" is only expanded, and there are probably a lot of technology and experience from the space agency inside.

But I haven't heard of the space agency doing research on the rotating simulation cabin. It seems that they are all practical technologies.

There are also super rockets, which are also practical technology.

But Mr. Yang has already talked about it before, so Li Future won't come up to talk about it, right?

probably not.

Because judging from the press conferences that Li Weiwei held before, he always kept short stories and didn't talk about repetitive content. This time...he probably won't either.

Sure enough, Li Weilai didn't say anything when he came up, and he didn't even walk to the center of the booth. Instead, he stood next to the big screen and started a CG video.

In the video, huge super rockets are rolled out of the vertical assembly building.

That kind of special "short and fat" shape, everyone can see that it is a super rocket being developed by Practical Technology, because it has no official name yet, so some fans named it "Big Fat".

When it was pushed onto the launch platform, it was sent into the sky with the sound of the countdown and the huge cloud of steam rising from the diversion tank.

When flying to a certain altitude, the booster is separated from the super spacecraft.

The "Big Fat" booster can land and be reused, and it does not land in the recovery ship at sea, but returns the same way.

Don't talk about wasting fuel, because liquid metal hydrogen is too capable and fearless.

The super spacecraft easily entered orbit, then opened the huge 20-meter-long cargo door, and then opened the top triangular door, releasing the huge 25-meter-long space station cabin.

This is the data marked in the video.

This cabin looks like an enlarged Tianhe core cabin. It is divided into a large column section and a small column section. The widest diameter is only smaller than the spaceship with a diameter of 20 meters, so people think of what Master Yang said several times. "Classic 18 Meters".

Sure enough, the data was quickly marked, and that was it.

The solar wings of the cabin are installed on both sides of the small column section like the sky and the core cabin, and the wingspan can reach 70 meters after deployment.

And the pressurized space of this cabin exceeds 4000 cubic meters, which is four times the pressurized space of the International Space Station, which can be described as "one cabin makes a station"!
Now people know that this is the commercial space station designed by Practical Science and Technology Aerospace Corporation.

The screen shifts to the interior of the space station.

As a commercial space station, it does not have all kinds of scientific research equipment and messy wires inside the scientific research space station. It makes full use of the wireless transmission technology of practical technology, which not only makes the space in the Starry Sky Inn very spacious, but also very classy.

It has a corridor in the middle and guest rooms on both sides.

It is said to be a corridor, but it is actually located in the "big playground" in the center, where space tourists can play a game of space volleyball.

There are models representing tourists in the guest rooms, allowing the audience to clearly compare the size of the rooms.

Compared with the sleeping bags and "sleeping cabins" in conventional space stations, the standard guest rooms here have a floor height of 2.5 meters and an area of ​​about 6 square meters. There are also separate toilets, wardrobes, Internet TVs and portholes.

The deluxe room is larger, not less than 10 square meters.

In addition to the private guest rooms, there are public areas, including a fitness game room, a restaurant, and an observation room with huge viewing portholes.

Finally, the camera came out of the cabin, stretched farther and farther, and fixed on the photo of the space station and the earth.

The name of the space station is reversed from the back of the earth, that is - future amusement park space station!
