Vol 3 Chapter 189 leap karman line

Therefore, the spaceship consumes time mainly in acceleration and deceleration.

Although for the aircraft using the anti-gravity propulsion device, the first cosmic speed of 7.9KM/S is of little significance. After all, as long as there is an acceleration, it can leave the blue star.

But if you want to go to the moon, the speed of the spacecraft must be as fast as possible, because the earth-moon system is also in real-time motion, and if the speed is slow, it will not be able to catch up with the moon.

Zhao Yuxi obviously didn’t understand this truth. She looked at the almost unchanging scenery on the monitor for a while, and finally got tired of it. She and Yang Qing had gone somewhere for a long time.

The biggest highlight here is probably that when the spaceship passed through a large cloud, the entire field of vision suddenly became pale, but it quickly passed through.

A cloud has a mass of at least several hundred to several thousand tons, but its density is too small, so that they occupy a rather large volume, which can completely accommodate several spaceships like it.

Fortunately, in the spaceship, the signal is directly full. She can do whatever she wants, follow the drama if she wants to, watch the short video if she wants to watch the short video, and occasionally play a few in the exciting battlefield.

Since she started practicing, both her nerve response ability and hand speed have increased a lot. She has transformed from a rookie in the game to a top player in an instant.

However, as the altitude of the spacecraft increased, the scenery outside gradually changed. From the original blue sky, it gradually darkened and turned into a dark blue color. This is the color at an altitude of 10,000 meters. See.

This is because as the altitude of the spacecraft increases, the atmosphere becomes thinner and thinner, and less and less blue light is scattered, while other light increases.

At a higher altitude, more than 14,000 meters, because purple is reflected, the color of the sky seen from there is dark purple.

And in the equatorial region, the sky will turn black and purple when it is more than 21 kilometers above the ground.

Farther up, the scattering from the atmosphere would disappear completely, and we’d be able to see the background color of the universe, pure black.

Because on the flying spaceship, not to mention her, even Yang Qing didn’t have any work to do, so Zhao Yuxi took a rare leisurely break from the busy work, and she was still a little uncomfortable for a while.

But after a day, she can be regarded as comprehending the true meaning of leisure, occasionally looking at the outside world, a little bit of changing sky, and then swiping her phone, asking Bai Yi to make herself a cup of milk tea and some snacks, and in a short time become Get comfortable.

At this time, she didn’t want to be tired of being with Yang Qing anymore.

In fact, they have always been a strange couple, and they have been in contact for a long time, probably because of Yang Qing. The time they spend together is really pitiful, and they are gradually getting used to living at a distance from each other.

Now let them act like ordinary couples, dating all day, watching movies and the like, and they are a little uncomfortable with each other.

At seven o’clock in the evening, he reappeared in the main control room.

“Yuxi, the spaceship is now crossing the Karmen line.”

“Have you reached the Karman line? That means we’ve gone into space.”

After studying spaceflight knowledge for so long, Zhao Yuxi has a good understanding of the Karman line.

This is about a hundred kilometers above the ground, basically at the bottom of the thermosphere, which is the dividing line between outer space and the atmosphere.

Above this altitude, traditional aerodynamics basically fail, and aerospace technology begins to play a role.

Although this standard is actually not clear, and there is no obvious sign, but this is a historic scene after all, that is, their spacecraft officially entered space.

Looking back now, the atmosphere has already turned into a black background, only the blue star, which relies on the color of the sky reflected by the ocean, still maintains the characteristics of azure.

Although passing here means that Yang Qing and Zhao Yuxi have officially become one of the hundreds of humans who have entered space, but Zhao Yuxi doesn’t seem to feel any excitement, as if this kind of opportunity, which was one of the few in the past, doesn’t really matter Same.

Maybe it’s because this trip into space is too ordinary, just like a trip that you can just leave and go, like going out and getting on a plane.

But here is more relaxed than flying, there are no restrictions, and there is no need to worry about seat belts or airflow interference.

Zhao Yuxi silently magnified the background of Blue Star, asked Xiao Ai to take a photo of her as a souvenir, and then silently sent it to Moments.

Just a photo, without any explanation, made the circle of friends boil.

“This picture is very good, just like the real thing!”

“Xixi wants to travel in space? Why don’t you book a ticket.”

…

Zhao Yuxi looked at the various associations in it, and in order to keep it secret, he didn’t answer, but was secretly proud in his heart.

Now there is no color outside, and it has completely become the background of the universe, but Yang Qing became serious, sitting here, staring at the screen, never leaving.

Because at this point, the atmosphere is no longer able to protect the spacecraft, and all kinds of micro meteors and space junk can freely attack any aircraft.

Yang Qing’s consciousness was connected with Xiao Ai, and he could feel that in just a few minutes, the spaceship passed by several fragments of space junk.

Of course, these garbage are extremely tiny, and only such tiny garbage can persist at such a low altitude for a period of time without being caught by the gravity of the blue star.

Of course, what awaits them is the fate of being pulled in by gravity ~www.readmtl.com~ and then burned in the atmosphere.

Although there is not much air remaining outside, but in contact with the spacecraft, it can also be clearly felt that the temperature nearby has begun to rise rapidly.

This is the thermosphere, generally between 500K and 2000K, and there is an ionosphere above it, and the air molecules inside have already shown a plasma state.

However, the air here is extremely thin, and the conduction ability is extremely weak. Even without the protective cover, the spacecraft will not heat up much.

Anyway, since humans launched rockets, it has never been heard that the rocket crashed due to the high temperature of the thermosphere.

This is the same as the thermal layer that exists around the solar system in the prediction. In a near-absolute vacuum, a few hydrogen atoms, no matter how high the energy level is, there is no threat at all.

The spacecraft continued to rise, and when it reached more than 500 kilometers, there was another threat, that is, various low-orbit satellites.

From here to an altitude of 2,000 kilometers are the orbits of various low-orbit satellites. SpaceX’s Starlink satellites are the most famous. SpaceX uses Starlink, a low-orbit satellite, to provide broadband services to the world.

Although the original intention is good, there are too many Starlink satellites, there are already hundreds of them. If it weren’t for their existence, Xiao Ai’s chosen launch time should be earlier.
