With the adjustment of the intelligent flight control system, the flight mode of the Xinghai has been switched.

The Star Sea, which has changed its flight posture, is like a sharp arrow heading towards the farther deep space.

After confirming that the flight mode switch was smooth and the Xinghai was working normally, Xu Chuan felt relieved and looked at the surveillance screen.

The radar and shooting devices deployed everywhere on the Xinghai will have clearly recorded the scenery at the altitude of dozens of kilometers.

In the images that were shot and passed back, there were no ground buildings, only white clouds and a blue sky.

At this moment, at the foot of Xinghai, this blue planet has already shown an arc edge. When crossing the edge, it is the deep and boundless universe.

And right in front of Xinghai, a sun was completely different from what you saw on the surface of the earth. It was white and bright, and its radiance scattered on the boundaries of the earth like a prism, dazzling and charming.

This is the critical point and the height close to the top layer of the stratosphere.

Further up, the density of the atmosphere will drop to a fairly low value.

At this time, the air can no longer provide enough working fluid, and the Xinghai can no longer provide the power to rise through the wings.

Therefore, it needs to switch flight attitude and flight mode, and continue to move towards outer space by carrying more efficient propulsion and increasing engine thrust.

Looking at the videos and images transmitted back by Xinghai, Xu Chuan watched them intently.

Standing beside Xu Chuan, Academician Chang Huaxiang also muttered to himself: "So beautiful?"

Although he did not stand in the high altitude in person, the images passed back from the first perspective witnessed a grand miracle.

The stretches of white clouds and the blue ocean shine brightly under the bright stars, and are incredibly beautiful.

Nothing is more shocking than this.

Looking at the blue planet with increasingly obvious arcs, Xu Chuan sighed softly: "Yes~, it's like a magical dream world. Next time I must go up and take a look."

As a scholar and a physicist at the top of the world, probably nothing attracts him more than the vast universe.

One of the dreams that I could not fulfill in my previous life was to step into the galaxy and take a look at the beautiful sea of ​​stars.

In this life, Xinghai was successfully completed in his hands and will also take him to see the blue earth, the distant starry sea and the future.

On the side, Academician Chang Huaxiang came to his senses and turned his head to look at Xu Chuan standing beside him, with a strange look on his face.

He wants to go up? Is it possible?

Probably, it seems...it's impossible?

At least it is unlikely that this person will be put on the top to take risks. At least it shouldn't be until the technology is fully mature...

From the surface to outer space, even to the lowest low-Earth orbit, it is a very long distance.

As for the entire earth, the closer it is to the core, the greater the density of the matter. The atmosphere is part of the earth, and naturally follows this law.

Of course, compared with the solid part of the earth, the density of the atmosphere is much smaller than that of the solid part of the earth.

In the history of science development, based on the distance from near to far from the surface, the current scientific community roughly divides the atmosphere into these five parts: the troposphere, the stratosphere, the intermediate layer, the warm layer, and the escape layer.

The troposphere is the part of the atmosphere closest to the Earth's surface. It exists between 8 and 15 kilometers from the ground, while the stratosphere is above the troposphere, within a range of about 15 to 50 kilometers from the Earth's surface.

The most common stratosphere is ozone gas, which forms a thick ‘barrier’, which is closely related to life on the surface. Without this “barrier”, the earth’s temperature will rise sharply, ultraviolet radiation will increase, life will gradually die, and the earth will not be inhabited.

The height from the top of the stratosphere (50 kilometers) to 85 kilometers is the intermediate layer, and the climate here is very cold and the air is extremely thin.

The Star Sea, which is constantly accelerating upward, has climbed the middle layer in a short period of time, walked up 15 kilometers, and reached the internationally defined low-Earth orbit.

Near-Earth orbits have no recognized strict definition. Generally, near-circular orbits with orbital heights below 2,000 kilometers can be called low-Earth orbit.

Of course, the algorithm of low-Earth orbit that goes up by 100 kilometers is generally based on the default algorithm of each country for the altitude of land and airspace.

If calculated based on the altitude where the spacecraft does not fall immediately if it does not fall down without power, the lowest altitude of low-Earth orbit is 160 kilometers.

The distance of 400 kilometers does not sound very far. On the ground, it can be reached in more than an hour by the high-speed rail.

But in the space activities against gravity, it is a very long distance.

Of course, this altitude still has a thin atmosphere and will also be affected by the gravity of the earth, but the unpowered spacecraft can maintain operation for a long time at this altitude.

Therefore, most of the time the aerospace world regards the altitude of 160 kilometers as the lowest low-Earth orbit.

This time, the Xinghai climbed and tested the altitude of about 400 kilometers.

This altitude is the most frequent altitude for conventional low-Earth orbit satellites, the International Space Station and other spacecraft activities. Here, Xinghai will stay for 24 hours, complete a series of its own detection and testing, and conduct some space experiments.

...........

As time goes by, Xinghai continues to rise, one hundred kilometers, one hundred sixty kilometers, three hundred kilometers...

Each report makes the joy on the face of the control center stronger.

With the rise of altitude, the output power of the fusion reactor and the aerospace engine has gradually decreased. In hundreds of kilometers of outer space, the gravity and air resistance have become quite weak.

Finally, after a short and long waiting time passed, a crisp report aroused everyone's cheers again.

[Successfully entered the orbit! Xinghai has reached its target location!]

During the long voyage, after five hours, Xinghai finally arrived at the pre-determined orbit.

In the aerospace base, the loud national anthem rose at this moment. Whether it was the scientific researchers in charge of aerospace at the control center or the soldiers patrolling and standing guard outside, at this moment, a strong sense of pride and pride rose in everyone's heart!

Today, they have achieved unprecedented results!

Star Sea! Successfully carries everyone's dreams, carries humans' distant view of space, and sails into the vast deep space.

This is their honor and the brilliance of the motherland.
