Super technology leader

Ma Da and Jiang Hai are the trainee astronauts in this period. They monitored the docking between the Starry Sky Inn and the gravity simulation cabin.

Ma Da was the original policeman. He had contact with Tang Chao when he was catching spies at the Binhai Launch Center. Later, he resigned and participated in the pilot's commercial astronaut selection. After selection, he became a trainee astronaut of the pilot space company and trained for a while. After time, I came to the Starry Sky Inn for field training.

Just in time for this launch mission.

Jiang Hai is in the same situation as him, except that Jiang Hai is a computer engineer. He was also very interested in the pilot recruiting astronauts, so he came to sign up.

He often participates in physical exercises, after the physical fitness selection, and tested his professional knowledge, he was successfully selected.

When Ma Da and Jiang Hai felt that the Starry Sky Inn shook slightly, and then the green characters of "Connected successfully" were displayed on the screen of the control computer, they began to report to the ground command center.

The completion of the docking does not mean that their task is completed. In fact, this step is the beginning of the task.

After confirming that the docking was successful, the gravity simulation cabin began to slowly unfold the centrifugal force perception module, that is, the four irregular cuboid cabins.

Under the support of the channel structure, they slowly unfold and gradually move away from the central rotating module.

When they were deployed to the limit, the same arc-shaped fixed brackets extended under each arc-shaped cabin.

The fixed bracket of each cabin extends to the rear end of the other cabin and automatically locks, and the complete ring is finally formed.

This is not over yet. After this step is completed, it is the astronauts' turn to play.

They put on rigid extravehicular spacesuits with space maneuvering devices, and left the Starry Sky Inn to fly out to perform a simple fixed mission.

Connect another fixed bracket connected to the rotating shaft to the inner ring corner of the centrifugal force induction chamber.

After the sixteen fixed brackets are all connected and a lot of triangular structures are formed between the centrifugal force induction cabin and the rotating module, the gravity simulation cabin section is unfolded.

After they returned to the Starry Sky Inn and checked that the gravity simulation cabin was normal, the rotation mode of the gravity simulation cabin was turned on on the ground.

The reaction nozzle on the outer ring of the centrifugal force induction cabin sprays high-speed gas to assist the initial rotation of the simulation cabin. When it accelerates to a safe speed, the reaction nozzle stops spraying.

The two astronauts checked again, and after confirming that there was no problem, they entered the axis of rotation through the gate, selected cabin No. 1, and floated down the ladder with their legs down.

The motor was in front, and the cabin that was closer to the bottom felt the faster it fell. They hurriedly stepped on the stairs and walked down one step at a time.

In the end, they stood firmly on the floor!

It did not immediately bounce off the floor like before, and this time it fell to the "ground".

There was a slight ups and downs the moment he landed, and he walked two steps forward, feeling a bit like being in a thigh-deep pool, but he finally stood firm.

Jiang Hai followed closely, standing on the floor and looking at Ma with a surprised look, Ma also looked at him with the same expression.

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

"It feels amazing. I actually felt'gravity' in space, and instantly felt a lot thinner."

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

In fact, if you look closely, the faces of astronauts in space are all "fat". No matter whether his face is fat or thin when he is on Earth, what caused this change?

The reason is simple-weightlessness.

When we look at someone on the earth, we usually stand or sit in a standing posture. At this time, the person’s head is on top, and under the influence of the earth’s gravity, the body fluids and blood of the person are going down.

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

When lying in bed, the face will look slightly fatter.

When a person enters space under the condition of weightlessness, the body loses the influence of gravity, the body fluid has to redistribute, the blood flows up, and all parts of the body receive the same pressure from the heart blood supply, which of course makes the face look fatter, even Fatter than when lying in bed.

Because at this time, there is no difference in gravity between various parts of the human body.

This phenomenon is "space edema", which is a "normal" phenomenon that a person will appear in space, because when a person is in a state of weightlessness, the first thing that changes is the disappearance of the hydrostatic pressure in the person's blood vessels.

At this time, people will have facial swelling, accompanied by a feeling of head swelling.

This is not a matter of deceiving people to buy abductees in the sketch, and then talking nonsense, making people feel that their face is getting bigger and bigger. At this time, it is really big.

The face is large and light, and sometimes even frequent urination occurs. That is because the human body perceives the fullness of body fluid in the chest and head, giving the receptors a false signal of excess body fluid.

At that time, the endocrine system automatically regulates the body and excretes part of the body fluid in the form of urine, so people will experience polyuria.

Now Ma and Jiang Hai feel the "gravity", and the body fluids in the body begin to distribute again. Following the gravity, the facial congestion naturally feels better.

In fact, the current gravity of the simulated gravity cabin is not large, only 0.2G, which is about one-fifth of the gravity of the earth, which is larger than the gravity of the moon, which is also suitable for the current situation of astronauts.

Astronauts stayed in space for a period of time, and suddenly felt the earth's gravity of about 1G. There will be some discomforts. Now 0.2G is about the same. Astronauts can adapt quickly, but they can also produce a certain gravity effect to reduce the impact of weightlessness. The adverse effects of the body.

It is now far from reaching the 0.5G simulated gravity in the design. This is because the mass of the combined spacecraft is about 170 tons, and the 85-ton simulated gravity cabin occupies half of the mass.

This is because after the Starry Sky Inn was commercialized, the pilots successively moved something inside, adding 5 tons of mass, so that the two reached a balance in mass, otherwise the mass of the simulated gravity cabin was larger than that of the Starry Sky Inn.

In order to prevent accidents, the speed of the simulated gravity cabin is relatively slow. When you find a larger space station to dock, its speed can be mentioned a little bit.

The speed is slightly increased, and its simulated gravity can be increased.

There are only four space stations in the earth orbit, one is the Navigator’s Star Inn, and the other is the Tiangong Space Station, the International Space Station and the Inflatable Space Station. If you want to dock now, then the Tiangong Space Station is definitely the most suitable.

why?

Because the previous plan was like this.

So people soon discovered that Tianxia's Tiangong space station had changed orbit.

The location of the space equipment on the surface is public, and you can find it at any time as long as you want to. Therefore, as soon as the location of the Tiangong space station changes, some people will know.

When these people sent out the news, a large number of people soon learned.

Then they discovered that the locations of Tiangong and Xingkong Inn were getting closer!

"They want to dock?!"

"Damn, the Tiangong Space Station and the Starry Sky Inn must be docked, they are going to be integrated!"

"Good guys, I like to watch the space combination the most. The space station is really bigger, the better!"

Sure enough, under the witness of the audience, the Tiangong Space Station and the Starry Sky Inn completed the docking and smoothly integrated into a space station weighing about 280 tons.

In this way, the "counterweight" of the simulated gravity rotating cabin has reached nearly 190 tons. Compared with the almost 1:1 mass ratio before, it has now reached 2.2:1, which feels okay.

After the docking is completed and the inspection is no problem, the rotational speed of the simulated gravity rotating cabin has increased, and the "gravity" has also reached 0.3G, which is nearly one-third of the earth's gravity, and the astronauts can move in it better.

Of course, the astronauts mentioned here include the three astronauts of Tianxia.

"Haha, feel the'ground' again, this feeling is really good."

The astronauts said happily.

"We humans finally have a foothold in space."
