My technology affects the whole world

Musk's SpaceX is the only company in the world that has implemented recyclable rockets, and as the boss, even if he is not a technician now, he still knows the pictures shot by recyclable technology very well.

The picture shot on the left screen of the live broadcast room is very similar to the scene when they were experimenting with the recovery of the Falcon.

Musk's expression has never been more solemn. He looked straight at the screen on the left, and his right hand was unnoticeably trembling.

There are many top aviation experts from many countries who are also looking at the live broadcast screen on the left and sitting in their seats.

Although they have no experience in realizing recyclable technology, it does not prevent them from taking a closer look. Coupled with the video of recyclable rockets previously released by SpaceX, when they compared it, they found that the two perspectives were surprisingly similar.

Then there is only one truth, and that is that the rocket launched by Tianyu Xinghai this time may also use recyclable technology!

Yingjiang's leading position in aviation may be rewritten today. An expert from the Great Mao Country said.

The live broadcast is still going on. Although some people in China are surprised by the sudden split screen in the live broadcast room, it does not prevent them from continuing to watch. As long as the black screen does not explode, it does not prevent them from continuing to revel and dance.

Now the left side of the screen is the perspective of the rocket recovery thruster, and the right side is the perspective of the remaining rocket flying into space. It will fly another 20 kilometers and reach an altitude of 130 kilometers to release the satellite.

Obviously, the right screen must have completed the task first. Soon the viewers also noticed that the right screen entered space and launched 12 satellites like a goddess scattering flowers.

The 12 satellites, with the help of internal small booster rockets, flew back to their own orbits like 12 butterflies with flying wings, unfolded their wings of solar electronic panels, and started their own operations.

This is the last scene on the right screen, and it is also the scene that makes the domestic live broadcast room audience cheer for the third time.

Seeing this, everyone knew that the satellite was launched successfully, and the audience in the live broadcast room fell into a sea of ​​joy.

The barrage of congratulations filled the screen like crazy in the live broadcast room, and the people of Hunan who were watching at the scene were even more excited to dance, as if the national football team had entered the World Cup, and the whole place burst into enthusiastic Ocean.

On the contrary, a group of foreigners who paid attention abroad were dejected and cursed.

Baga, why did they succeed again?

Axiba, Ma Tian is from our country, why haven't you returned to our country, Smita~

My hair, God must be joking. A demon like Ma Tian should be killed by a falling rocket!

…

Of course, there is also a group of aviation experts looking at the final scene on the right screen in horror.

Smith, play back the video for me!

Osvki, you should record the video and play back the last scene just now!

Perhaps non-professionals only look at whether the satellite was successfully launched, but professionals see something deeper.

For example, how come this rocket carries 12 satellites! Are the flight altitudes of these 12 satellites marked wrong?

This is impossible, unbelievable, why can Ma Tian's satellite fly so low?

Si Kuo, Ma Tian is really a terrible scientist!

Damn it, how did Ma Tian do it? This is so awesome!

Professional people repeatedly replayed the last scene on the screen on the right side of the live broadcast room.

For them, from the screen, based on the positions and deviation angles of the launch of the 12 satellites, they can roughly figure out what orbit the 12 satellites will reach and what satellite lineup they belong to.

For example, Yingjiang's aviation experts quickly analyzed that Matian's 12 satellites will probably be in ultra-low orbits of 130 to 150 kilometers.

Maybe everyone thinks that the lower the satellite altitude, the simpler the technology may be.

But the fact is that it is very difficult to operate satellites in ultra-low orbit, that is, below 200 kilometers.

As we all know, the earth has an atmosphere. 90% of the mass of the atmosphere is below 30km. It gradually becomes thinner above 30km. And as the altitude increases, the air density drops sharply.

Since the satellite must fly at the first cosmic speed of 7.9km/s in order to remain above the earth, it is destined that the satellite's flight cannot be greatly disturbed.

If the satellite is flying in an ultra-low orbit, it means that it will face thicker air. As we all know, the thicker the air, the higher the resistance coefficient of the satellite through friction, and the greater the damage.

This is also the reason why many satellites have to fly at an altitude of at least 200km, because the air influence is smaller and the satellites are more stable.

When flying in ultra-low orbits of 120km to 200km, you need to consider the impact of air friction. The lower it is, the more difficult it is and the greater the technical content.

As early as 2015, many countries realized the advantages of low-orbit satellites.

According to calculations, if the satellite drops from an orbital altitude of 650 kilometers to 160 kilometers and maintains stable flight, the radar radio power demand will be reduced by 64 times, the communication radio power will be reduced by 16 times, and the optical performance will be unchanged. Aperture diameter requirements will also be reduced by a factor of four.

In other words, as long as ultra-low orbit satellites can operate normally, their communication efficiency or reconnaissance efficiency is far greater than that of high-orbit satellites.

Many satellites are still flying in high orbits above 200km. It’s not that they don’t want to go to low orbits, but that they can’t.

Nowadays, Tianyu Xinghai has achieved it easily, and it is still a very low 130 to 150km. This has to make the aviation experts around the world who are paying attention drop their jaws.

How did Ma Tian do it? Or did he just plan to fly and fall soon?

It shouldn't be. Ma Tian won't make such a mistake, right?

I don't believe that Ma Tian can achieve a sustained flight of 130 kilometers in orbit!

Immediately afterwards, a group of experts also began to question the height of Ma Tian's launch of the satellite. They did not believe that Ma Tian could fly at such a low altitude.

Yingjiang has already used his own low-altitude flying satellite to capture the position of the Tianyu Xinghai satellite below for verification.

The live broadcast is not over yet, and the rocket thruster view at the bottom of the left screen is still on.

Musk kept staring without blinking, not even paying attention to the launch of ultra-low-orbit satellites on the right screen.

In his field of vision, the viewing angle of the screen on the left began to get lower and lower, and the situation on the mainland was visible to the naked eye.

Musk knows that the most critical moment is coming. At this stage, the recovered rocket will start the anti-propulsion device for the final precise positioning and landing.

What made him despair finally happened. From the perspective, red flames began to appear at the bottom, and the appearance of the City of Progress became clearer and clearer.

The originally black screen on the right also began to give a third perspective, watching the bottom of the rocket that had been launched in the sky arrive above the City of Progress, and land steadily at the place where it was originally launched.

It's over! Musk collapsed in his seat and put his right hand on his left chest inadvertently. Why did he feel that his heart hurt?
