Super technology leader

Sure enough, listening to Tang Chao talking, people fell into imagination.

This is the largest man-made space station in history. The International Space Station can only be a thing of the past.

The longest is 109 meters and the longest is more than 300 meters.

The widest is 73 meters and the widest is nearly 200 meters.

The heaviest is 420 tons and the heaviest is about 2500 tons.

The pressurized space of less than 1,000 cubic meters is equal to 10,000 cubic meters.

How does this compare?

Moreover, it is heard that at the right time and place, such as the sunrise and sunset on the mountain, the reflection of the International Space Station is particularly obvious. At this time, its brightness is also the highest. If you use a SLR camera and a telephoto lens, it is possible to shoot the International Space Station. .

It is very difficult to shoot.

It is not only necessary to check the orbital position of the International Space Station in advance, but also to set the camera's focal length and exposure value in advance, and then aim at the sky. The whole process is relatively short when the ISS appears in the field of view.

But as long as it can be photographed, the outline of the International Space Station can basically be photographed clearly.

When all conditions are suitable and your eyes have a good look, you can see it with the naked eye. At most, it can be taken clearly without a single-lens reflex camera, just a single spot of light.

In fact, it is not only the International Space Station. Even ordinary artificial satellites may reflect sunlight to the ground when they unfold their solar panels. If the angle is right, people on the ground can see a fast-moving “star”.

They are often mistaken for UFOs.

Normal satellites and the International Space Station are like this, so can the Tianting Space Station, which is several times larger than the International Space Station, be able to see more clearly?

If the side of the unfolded solar wing is facing the earth and the conditions are right, is it possible to see the blurry outline of the light spot with the naked eye, and the telephoto camera can shoot a clearer structure?

Yes, in addition to the big ones, human beings like spectacles, but also visual animals.

[As long as the facial features are good, the three senses will follow the facial features]

It's not just about people, but also about machinery.

If you like the big ones and the spectacles, you have to be able to see them. Before the International Space Station could see a bright spot with the naked eye, then the Tianting Space Station could see the faint outline bright spot with the naked eye. Doesn't this contrast come out?

Netizens have bigger brains and speak freely on the barrage.

"Hurry up, I want to see the space station on the ground!"

"Think about the scenery, it should be very beautiful. I only saw the light spots passing by at night. I knew it was an artificial satellite or a space station, but I couldn't see what it was."

"In the future, there will be a template for propagating space exploration. After the lecture is finished at that time, you can point it directly to the sky and show them."

"It's a pity that such a large space station will not be transformed into a space fortress. Don't forget that there are aliens on Mars."

"Doesn't it have a manufacturing center and a repair shop in its industrial zone? The manufacturing center makes parts, and the repair shop can repair it and assemble it. Then in theory, can it be transformed into a rail shipyard?

"Good guy, are you talking about building spaceships directly in space orbit? I feel very clever, and I am excited when I think about it!"

"I think it may be a little difficult. After all, it is not a professional space shipyard. It should be more of a test. At most small parts can be built to ensure the maintenance of the sky itself, or to repair the satellites. Others... it can be repaired. Moon spacecraft?"

"It's hard to say, it depends on the problem of the Benyue spacecraft? If it is broken, a small thing should be repaired. If the engine is broken, the orbital repair shop of the Tianting space station is estimated to be unable to repair it."

"Speaking of so much, you have to wait for it to be completed. I don't know how long it will take to build such a large space facility?"

"Fast forward to the completion of the Tianting Space Station, and then I won the tourist ticket in the lucky draw. I can't wait."

When it comes to the specific construction process, this does arouse many people's concerns, after all, there are examples of the International Space Station before it.

It was built in cooperation with more than a dozen countries and it took more than a decade to complete.

If Heavenly Court is the same, and even takes longer because of its larger size, wouldn't the waiting daylilies be cold?

People nowadays are generally impatient. They can't wait to propose a plan today, and the finished product will be made tomorrow.

Of course, now that technology has advanced, and the participation of pilots, it shouldn't take that long.

However, calculating the space transportation equipment currently owned by Navigator and Tianxia does not seem easy.

Orbital shuttles can easily transport things to space. People now know that, but its cabin is too small, and it can only transport small parts and a small amount of raw materials.

The carrying capacity of more than two tons is too small.

Moreover, building a huge Tianting space station with small parts and raw materials is not as simple as building blocks. Astronauts must perform a large number of spacewalk operations.

Once it involves astronauts' spacewalking operations, it takes longer.

As far as current human technology is concerned, the method of construction of space facilities that requires welding in science fiction movies can only be continued in science fiction movies.

Therefore, the most suitable job for orbital shuttles is to transport people.

Then the best way to build the Tianting Space Station is to build various modules on the ground and then use rockets to transport them to space orbit to "assemble building blocks." This is the space facility construction plan that mankind is currently familiar with.

At present, the rocket that the Navigator can use is the Yuanhang super-heavy rocket. The Chuhang rockets are retired and the technology is sold to other aerospace companies.

The official rockets that Tianxia can use are the recycled version of Long March 9 and the recycled version of Long March 5. The other rockets are too small.

Especially the Long March 9 is very important for the construction of large space stations because it can use a fairing with a diameter of 10 meters.

It’s just that the navigator used to fly a rocket with a core stage diameter of 5 meters against a fairing with a diameter of 15 meters. The fairing of the Long March 9 rocket is not enough. The Tianting space station is too big and can carry more at a time. It’s always good for a module to be shipped, and some modules in the sky structure are indeed huge.

So a bigger rocket is definitely needed, bigger than the Long March 9.

Tang Chao also knew that, and later he had to build a manned spacecraft to fly to Mars, and the simulated gravity cabin would definitely be available.

This time I made a small gravity cabin for the test. The unfolded diameter is 30 meters, and the folded diameter is 15 meters. Now the astronauts participating in the test have some feedback, and there are many problems, basically related to the small diameter.

Then after building a Mars spacecraft, the diameter of the gravity cabin must be enlarged, and the folded diameter must also be enlarged. Yuanhang is estimated to be choking, and a fairing larger than 15 meters in diameter is estimated to be overturned.

The original design of the Long March 9 prevents it from messing around like the Yuanhang. Its fairing is more restrictive, and its expansion is estimated to be about 15 meters. It cannot transport the larger gravity cabin folding mechanism.

Therefore, larger rockets are just needed for large-scale space construction in the early days. At present, the best space facility construction method for mankind is to build them on the ground. It is best to assemble a few modules first, save the space and assemble them many times in space, and then directly use the large rocket. Ship to space and connect to larger modules.

Of course, astronauts can also perform some auxiliary assembly for the spacewalk, but it must be simple, just screw a screw, insert a slot, connect a wire and so on.

It would be embarrassing to make a long gap for astronauts to weld.

If the weld is not straight, but canine teeth, then the astronaut is autistic.
