This is how black technology should be used

Chapter 289 Gravity in Space
Astronauts put on extravehicular space suits with space maneuvering devices, leave the starry space station and fly out to perform fixed tasks.

For only 3 astronauts, this is a big project.

But it doesn't matter, soon three more astronauts flew up on the wooden kite to support them.

There are many fixed rods that are also folded on the unfolded rotating cabin. The astronauts first unfold them, and then use the motorized device to slowly move the other end to a fixed position to fix them.

There are also some flexible fixing cables sent up with the wooden kite. Both ends of the fixing cables need to be fixed and the degree of tightness must be adjusted.

But for astronauts, this is an acceptable job.

After half a month of busy work, 4 astronauts went out to work for 8 hours every day, and the remaining two stayed behind, which really made them tormented.

After all, this is not working 8 hours on the earth, but in space.

The thick extravehicular space suits not only restrict their work, but also the weightless environment makes them unable to use their strength.

And you can only go out for 8 hours a day, so you can't work longer if you want. After all, the thickness of the extravehicular space suit is far different from the bulkhead of the space station, and the radiation protection capability is limited, so the working hours are also limited.

Half a month later, the installation of the rotating simulated gravity cabin was completed. Many triangular structures were formed between the fixed rods and cables and the original structure, which ensured the structural strength of the rotated simulated gravity cabin.

The construction of the first rotating simulated gravity module is completed, and the second will be delivered immediately.

This time, only half a month has passed since the last launch of the Optimus rocket, and the inspection results are still perfect.

It also shows that its reusability is very strong!

With this mission comes six new astronauts.

The astronauts who assembled the first gravity module returned to the ground. They need to undergo examination and medical treatment to see what the impact of the "high-intensity" extravehicular work for half a month is.

The second gravity module was also assembled for half a month, and when it was assembled, the time entered June.

For a whole month, the astronauts and ground support teams were busy enough, but audiences all over the world enjoyed watching it.

Because every time I go out of the cabin to "tighten the screws", there is a live broadcast!

It can be said that the two rotating gravity simulation cabins were assembled bit by bit by audiences all over the world.

Well, the whole world... the audience who watched this live broadcast.

However, the data of Practical Technology can guarantee that these audiences are definitely from all over the world, properly "worldwide".

But now, the most critical moment has come, and no one wants to miss it.

The second batch of "space engineers" is more blessed than the first batch, because they will be the first batch of human beings to experience the simulated gravity in space!
After all, the assembly is complete, and returning to the ground is not a day or two away.

So when they returned to the Starry Space Station, took off their heavy extravehicular spacesuits, and heard from the ground and the partners who stayed at the space station today that the rotating simulation gravity module had detected no abnormalities, the command center ordered the initial rotation of the gravity simulation module.

In the rotation simulation, the engine outside the cabin ejects high-speed gas to assist the initial rotation of the simulation cabin. After accelerating to a safe speed bit by bit, the engine shuts down.

The rotation directions of the two rotating cabins are opposite, which can offset the torque and prevent unnecessary deflection of the rotating cabin with the entire space station.

When the astronauts got together to the hatches of the pivoting cabin and the "Tianmen" cabin, the audience watching the live broadcast subconsciously held their breath.

Because this is a historic moment!
The astronauts checked again and opened the hatch after confirming that there was no problem.

They flew into the pivot cabin, chose the... mess room, and floated down the ladder with their legs down.

The closer they got to the cabin below, the faster they fell, so they quickly stepped on the stairs and walked down step by step.

Finally, they entered the restaurant cabin one by one and stood firmly on the floor!
It didn't bounce around immediately when it touched the floor like before. This time it fell to the "ground" and it just fell to the "ground".

The moment they landed, there was some ups and downs, and they took two steps forward, feeling a bit like being in a thigh-deep pool, but they finally stood firm.

They were all wearing cabin uniforms, and everyone could see each other's expressions. They first looked around curiously, and then looked at each other in surprise.

"Haha, we actually stood firmly on the ground in space."

"Actually, it's not that stable, it's still a little bit floating, but it's really standing still!"

"I asked you if you are happy?"

"Cool!"

"This feeling is amazing. I actually felt 'gravity' in space, and I felt a lot thinner in an instant."

"I don't know if it's an illusion, but I'm a little dizzy. Could it be that I've been floating for too long?"

The instant thinning in front is of course a psychological effect, but it is not just a psychological effect.

In fact, if you look carefully, the faces of astronauts in space are all "fat", no matter whether they are fat or thin when they are on the earth, so what caused this change?

The reason is simple - weightlessness.

After thousands of years of evolution, human beings have already adapted to the environment of the earth. When looking at someone on the ground, they usually stand or sit.

At this time, the head of the person is on the top, and affected by the gravity of the earth, the body fluids and blood of the person all go down.

When blood flows from the heart, it is of course easier to transport blood to the legs than to the head, so your face looks thinner when you stand.

When lying on the bed, the face looks a little fatter.

However, when a person enters the weightless condition of space, the body loses the influence of gravity, the body fluid has to be redistributed, the blood surges up, and the pressure of the blood supply from the heart is the same everywhere in the body, which of course makes the face look fatter, and even He is fatter than when he was lying in bed.

Because at this time, the various parts of the human body do not have any gravity difference.

This phenomenon is "space edema", which is a "normal" phenomenon that occurs when a person is in space, because when a person is in a state of weightlessness, what is changed is the disappearance of the hydrostatic pressure in the blood vessels of the person.

At this time, people will have facial edema, accompanied by a feeling of fullness in the head.

Moreover, the face is considered light, and sometimes even frequent urination occurs. It is because the human body perceives that the chest and head are full of fluid, which gives the receptors a false signal of excess fluid.

At that time, the endocrine system will automatically adjust the body and excrete part of the body fluid in the form of urine, so people will have polyuria.

They feel the "gravity" now, and the fluid in the body begins to distribute again, following the gravity downward, and the congestion on the face naturally feels better.

In fact, the current gravity of the simulated gravity module is not very large, only 0.4g, which is about 40% of the earth's gravity, which is similar to that of Mars.

However, it is also suitable for the current situation of astronauts.

Although they didn't stay in space for a long time this time, only half a month, but their bodies have fully adapted to the space conditions, and there will definitely be some discomfort when they suddenly feel the earth's gravity of about 1g.

Now 0.4g is about the same, astronauts can adapt quickly, but it can also produce a certain gravity effect, reducing the adverse effects of the weightless environment on the body.

In order to generate a gravity similar to that of the earth, the diameter of the rotating cabin must be larger, which cannot be controlled by the current starry space station.

Even now, the 100-meter rotating cabin is much larger than the previous space station.

After all, if solar panels are not counted, the radial length of the two experimental cabins connected to the node cabin is only about 50 meters.
