Chapter 547 The Evolution of Betelgeuse
After entering the [-]-kilometer low-earth orbit, under the control of the intelligent core of the spacecraft, the No. [-] spacecraft changed its flight status and stopped ascending, but began to fly around the simulated earth at the first cosmic speed.

Here, Won will launch a series of test operations including orbit change flight, pressure adjustment in the spacecraft cabin, sanitation system test, circulatory system reciprocating test, eating, weapon use, shield defense, etc.

In addition, the X-1 industrial robot will replace him and place all kinds of vegetables, fruits, plants and other vegetation and seeds in the space environment.

One is to observe the possible impact of cosmic rays on life activities, and the other is to find various optimization directions for plant mutations.

These two things will last for about 36 hours. After completing this series of flight tests and scientific investigation activities, the zero spacecraft will start again and change orbit to the moon.

The test time of about 36 hours is not very long. As planned, the zero spacecraft restarted the magnetic field anti-gravity engine under the instruction of Won, and was ready to go to the moon.

Compared with climbing from the ground to the low-earth orbit of [-] kilometers, it is a long journey from low-earth orbit to the moon.

Even if he was driving a vehicle like Spaceship Zero, it would take about 36 hours.

However, compared with the reality that countries use launch vehicles or space shuttles to go to the moon, 36 hours is not even a fraction.

Take the Chang'e series of probes that landed on the moon in Huaguo as an example. It takes about 11-14 days to travel from the earth to the moon.

First, astronauts need to take a rocket to lift off from the center of danger on the ground and then enter Earth orbit.

This time is about 16-18 hours. After flying around the earth for a certain period of time, the spacecraft will rise to another orbit, which is farther away from the earth and closer to the moon.

In this secondary orbit, the spacecraft needs to fly for another 24 hours before performing its next maneuver.

After flying in the secondary orbit for 24 hours, the spacecraft will rise again to the 48-hour third-level orbit, making two orbits around the Earth.

At this point, it still can't fly directly to the moon, and needs to rise again after completing a 48-hour cycle to enter the moon landing orbit.

After entering the lunar orbit, the spacecraft can start to go to the lunar orbit. Some spacecraft still have a certain acceleration ability at this stage, while others do not. They can only float at the original speed. The shortest time is 3-4 Days or so, long takes 5-6 days.

When it approaches the orbit of the moon, it will be captured by the gravity of the moon, then it will start to slow down, stay in orbit 200 kilometers from the surface of the moon, and then it can land safely on the surface of the moon.

The whole process is quite cumbersome and complicated, and requires changing the flight trajectory and calculating countless data.

Once there is a problem in one of the links, it is impossible for the spacecraft to reach the moon, and it will only disappear into the vast universe.

Therefore, the exploration of aliens, especially the artificial moon landing, requires not only technology, but also courage.

Of course, these various forms of orbital changes are not necessary for Won who is sitting on the zero spaceship.

It's not that he doesn't need to change tracks, but the number of changes is not that many.

Won only needs to consider the impact of the earth-moon activities on the progress of the Zero spacecraft, and other things can be handed over to the intelligent core inside the spacecraft for correction.

The various probes and satellites launched into the sky in the past one or two years are not for nothing, if he already has a fairly complete set of solar system data and information.

The data recorded by the probes and satellites not only marked and reflected the specific data of each planet in detail, but even every meteorite in the asteroid belt between Mars and the parent star was completely recorded.

According to these data, Won can even plan a series of 'highways' in the solar system.

These highways can almost completely avoid all obstacles, such as meteorites, high-density interstellar dust and other things, which can ensure that the spacecraft will not encounter obstacles during flight.

It's a pretty stat-heavy thing, but not too difficult.

After all, the solar system has existed stably for billions of years. If there are no special circumstances, things like stars, meteorites, and interstellar dust floating in space will not easily change their orbits.

Although some meteorites and interstellar dust will also fall under the gravitational influence of planets, they are only a small number compared to the overall number.

If the [-]-hour flight time is put into reality, it can be said to be short and cannot be short.

There may even be a scene of earth-moon travel.

After all, it takes more than ten hours to fly from China to the United States.

But for South Korean won, the flight time of nearly one and a half days is too long.

In the vast universe, there is nothing but the earth that is gradually moving away and the sun that is shining with light.

Don't look at the excitement of seeing the stars twinkling in the outer space in the sky at night, but when you really come to space, you will only feel the boundless loneliness.

The Milky Way has more than 2000 billion stars, but compared to its size, the number of stars is no more than a hundred grains of sand mixed in a swimming pool, which will appear abnormally empty.

This also aroused the curiosity and discussion of the audience in the live broadcast room.

[Where are the stars?Why can't I see a single star? 】

[Yes, there are so many stars in the sky, why is there none? 】

[It stands to reason that the stars that can be seen on the earth should not be seen more clearly in the sky without the isolation of the atmosphere? 】

【Little Heizi is showing his feet?I just said that this is just a computer-generated picture, how could it be a real artificial moon landing. 】

[No, the telescope can shoot and see the stars, why can't the anchor here see them? 】

[It should be a problem with the shooting angle. The background of the picture presented by the anchor is the earth and the sun, visible light and reflected light. The sun blocks the light of other stars. 】

[Look at another angle?Haven't seen what it's like to see outer space with the naked eye. 】

[I remember that the moon landing photos taken by NASA in the past seemed to be unable to see the stars, including the artificial moon landing, so many people suspected that the moon landing was fake. 】

[In outer space, if the angle is wrong, you really can’t see anything except the darkness and the occasional twinkling stars. 】

[The anchor took a shot from a different angle, looking at the stars in the universe. 】

Looking at the barrage on the virtual screen, Han Yuan smiled and explained: "It's not that I don't want to take pictures of outer space, but that there is actually nothing in the pictures."

As he spoke, he stretched out his hand to manipulate the virtual projection screen, and turned the perspective screen to the outer space facing away from the earth and the sun.

On the screen, it was pitch black, like an abyss that could swallow everything.

Seeing this scene, the audience in the live broadcast room were a little dazed.

Normally, there is no air or other obstacles in space, and the stars in space should be clearly observed at any time, and theoretically even brighter and clearer.

But the picture that will be taken is dark and nothing.

This is a bit unscientific.

Seeing these confused bullet screens, Han Yuan smiled and explained again: "This is not scientific or unscientific, it is a very normal thing."

"Actually, friends who know a little bit of photography know that even on the earth, it is very difficult to take pictures of the sky full of stars. It is almost difficult to do this without professional equipment, and the exposure of the camera used in space is very difficult. Not enough conditions make it difficult to discern distant starlight in the background."

"In addition, in the solar system, the sun's light is too strong. Even though the sun-facing side can theoretically see the stars, they are actually covered by the sun, and on the shady side, there is no exposure. conditions, so it is still impossible to capture those beautiful stars.”

"That's why the pictures taken by the shooting equipment outside the spacecraft are pitch black."

"In fact, the naked eye can see the stars in space, and the shooting equipment around me should have enough conditions to shoot them. I can take you to see them."

With that said, Han Yuan got up and walked towards a sub-cabin of the spaceship.

Due to the position of the cockpit, it is located in the center of the spaceship. It is not possible to see the space with the naked eye. If you want to see it, you need to go to the designated sub-cabin.

The shooting equipment installed on the outside of the spaceship cannot capture the faint starlight without long-time exposure processing, but the shooting equipment provided by the system around him should be able to.

After all, when he was simulating the earth, he had photographed the Milky Way for the audience to see.

In addition, the naked eye can also see the galaxy in the vast universe.

The absolute resolution and performance of the human eye is nothing compared to a video camera.

Cameras can provide the visual effects of fisheye lens equal-area projection and equidistant projection, but human eyes cannot.

Cameras can provide visual effects from ultra-wide-angle to ultra-telephoto, but the human eye still cannot.

The human eye can only see the central resolution of the image field, and the surrounding area is full of defects.

Speaking of functions, it is actually an imaging system with only central resolution and edge resolution, binocular 3D vision, blind spots, and a low refresh rate.

But the bug is that the human eye is connected to the brain.

Just like a camera has a processor in addition to the photosensitive element, so many things are not only obtained by the naked eye, but also processed by the brain.

For example, the backlit portrait by the window, the human eye + brain is actually the HDR synthesis in the camera.

However, the automatic synthesis effect of the current shooting equipment is simply not as good as the synthesis of human eyes + brain.

Therefore, most of the shooting equipment cannot directly see and shoot the stars at night like the human eye.

Even the Hubble Telescope needs a long time of exposure and focus to take a clear photo.

Get out of the cab, board the elevator, enter the highest floor of the core cabin, and then walk through the arm connecting the sub-cabins, and come to the special sub-cabin for scientific research observation experiments.

Compared with other sub-cabins that are almost fully enclosed, this sub-cabin for scientific research and observation can open part of the bulkhead.

It is replaced by a special tempered glass, through which the outside situation can be clearly seen with the naked eye.

But correspondingly, the protection capability of this sub-cabin is weaker than that of other sub-cabins. If a war breaks out, this sub-cabin will most likely be destroyed first.

However, there is no way to do this. Enhancing the function of a certain part will inevitably mean giving up something. After all, there is no such thing as perfect.

When Han Yuan came to the sub-cabin numbered three, the bulkhead had already been opened under the intelligent control of the spacecraft.

Almost an entire side of the bulkhead was completely opened, revealing the pitch-black space outside and the dazzling white sun.

Seeing the sun from space is a completely different experience than seeing it from Earth.

On the earth, due to the influence of the atmosphere, most of the light waves are absorbed by the atmosphere, so that most of the sun seen by the naked eye is yellow or reddish yellow.

In space, there is no atmosphere that can absorb light waves, and the sun's rays face the spacecraft directly, and it is white to the naked eye.

As for the yellow, red and other close-up pictures of the sun that ordinary people see on the Internet, they are usually taken by special cameras, such as infrared cameras.

Because of these pictures, it is possible to see more clearly what is happening on the surface of the sun, instead of being unable to see anything clearly in a vast expanse of whiteness.

After Wei Wei covered the light with his hand, Han Yuan issued an order to adjust the flight attitude of the zero spaceship.

Adjust the No. [-] cabin from the angle of the front sun to the back.

The sea of ​​stars in the distance suddenly appeared in front of everyone's eyes.

Compared with the Korean won standing by the glass, the audience in the live broadcast room saw it even earlier.

The shooting equipment provided by the system is more powerful than the human eye. When the human eye is still adapting to the light and adjusting the focus, the shooting equipment has adjusted the shooting method in real time, and the scene in space is completely captured in the live broadcast room.

【What a nice view! 】

[There are stars!Can see the stars! 】

[Whoever says fake and invisible, stand up! 】

[It's so clear, it's much clearer than seeing the Milky Way from the earth. 】

[The one in the upper right corner is Betelgeuse, right?Its light was so strong that it covered all the surrounding stars and it was pitch black. 】

[Compared to the empty space, I’m nothing, my crap is nothing, what should I do if I’m happy! 】

[Space is so big, why doesn't it have my [-] square meters? 】

[I used to like watching cosmic documentaries and thinking about life. 】

[In the end, you will find that your life is meaningless at all_]

[Betelgeuse is absolutely amazing, it still drags two tails, is it a gamma ray burst? 】

[Will the supernova explosion last that long?Didn't you say it happened in an instant? 】

[Station B has the cosmic probability film "Cosmos" season 1-8, which has been updated to 118 episodes. It is strongly recommended to watch, and you will find out after watching it.】
