With such drastic weight changes and multiple out-of-orbit adjustments, the fuel output from the engine nozzles needs to be controlled with extreme precision.

So the difficulty of hovering this time is definitely not half a star.

If you use human hands to control.

It's an almost impossible task.

This can only be done by sensing devices and algorithms.

The question is how can there be such an awesome algorithm in the world.

The little dragonfly X1 will translate again for 500 meters and move back.

The engine is shut down at this time.

The rocket also lost the power to maintain hovering.

The grid wings open.

The rocket slowly fell.

Although the height is only more than 500 meters, as the distance between the ground and the ground decreases, the speed of the fall is getting faster and faster.

10 meters per second...... Twenty meters per second ...... Thirty meters per second......

The speed at which the rocket is falling is also getting faster and faster.

Everyone was going to be a little nervous.

Everything was perfect before.

But the most important thing is landing.

If the landing fails, no matter how perfect it is, it is just a failure of perfection.

However, the four small things on the rocket body also attracted everyone's attention.

It seems that these four things can be constantly adjusted.

The rocket body can also keep the center of gravity stable.

Everyone present will already admire it.

Such a small design can make such a big difference.

I really don't know who came up with it.

Just when the rocket was still more than a hundred meters from the ground.

The engine starts again.

The powerful reverse thrust slows down the descent of the rocket rapidly.

Fifty meters per second...... Thirty meters per second...... 10 meters per second...... 5 meters per second ...... All the way down to one meter per second.

The rocket is already only a few meters above the ground.

Huge smoke swept all around, obscuring the entire rocket.

Under the cover of smoke and dust, the rocket speed continued to decrease.

Finally, it reaches a speed of 0.5 meters per second.

Slowly landed on the ground.

However, the people in the hall will not be able to see if the rocket has landed successfully in the end.

Because the smoke has obscured the camera.

Everyone was a little nervous.

Of course, Su Han was also a little nervous.

The point is that it is not convenient to ask Shenlong in this environment now.

I can only wait.

After a while!

The clouds of white water droplets in the air dissipated.

The little Dragonfly X1 rocket is still standing there.

There was a burst of cheers in the control hall and on the factory floor.

"Boss! We succeeded. Of course, Pan Chi was excited.

A smile appeared on Su Han's face.

For him, as long as he succeeds once, with the precise control ability of the divine dragon, he can succeed every time.

It seems that the real rocket test in the sky is not far off.

The elders of the surrounding aerospace circles came to congratulate Su Han one after another.

At the same time, I am also envious in my heart.

Before, when Su Han said that he wanted to engage in rocket recovery.

Everyone thought that Su Han was crazy at all.

It's simply not good or bad.

Now the slap in the face is that the other party really succeeded.

It's just a hover test though.

But how difficult it is during this period, everyone has seen it with their own eyes.

The future of global rocket launches may all depend on this success.

There was a huge change.

The great era of commercial rockets may really be coming.

……

A few days later.

The official website of Longhan Technology officially announced this matter.

And it goes with a video.

Not all the videos though.

But there are still key frames for the take-off, hovering, moving, and landing of the Little Dragonfly X1 rocket.

The video once again shook the world.

Actually, two years ago.

When Su Han had just proposed to engage in rocket recovery.

Everyone thought Su Han was bragging.

Because it's simply not possible.

No country in the world has ever completed rocket recycling.

Even the Mi Federation has only tested some weird so-called prototypes once.

But then I also gave up.

Because the relevant data shows that rocket recovery is simply not possible.

At least a normal rocket is impossible.

But now the little dragonfly X1 that slaps people in the face is a normal rocket.

When everyone saw that the little dragonfly X1 easily completed the 500-meter climb, and also moved back and forth laterally for hundreds of meters, and finally landed smoothly.

Everyone was blown away by the content of the video.

Although, judging by the video, it was just a simple rocket hovering test.

It's not really rocket recovery.

But there is only one company in the world that can do this to this extent.

A private company has taken the lead in completing technology that no other country in the world can do.

That's awesome, isn't it?

Major media and newspapers around the world have reported on this matter at great length.

Some media even directly said that the rocket technology of the Huaxia people has surpassed the Mi Federation.

Naturally, it made the top of the Mi Federation angry.

The Mi Federation has always boasted of being the ceiling of the global rocket launch field.

Even a manned landing on the moon was completed.

The embarrassing thing is that these were decades ago.

Now the rocket launch technology of the Mi Federation is not as good as before.

Every time you give someone away to the International Space Station, you have to rent a rocket from the bear country.

This will be a Mi Federation, let alone send people to the moon.

Even the performance of its own engine is not powerful.

Not to mention the production of rockets that can be recycled.

The Rice Federation doesn't know where to start.

Originally, Su Han said that he wanted to make a rocket that could be recycled.

The experts at NASS also say that it is simply impossible.

The top of the Mi Federation also believed the words of these experts.

But what makes people slap in the face is that they have really achieved it.

And it came true so quickly.

This is absolutely unacceptable to the Rice Federation.

The official unit of the United States immediately called a meeting of NASS experts.

Study the matter of recovering the rocket on the horse.

But these NASS experts believe that recovering the rocket is simply impossible.

Even if Longhan Technology completes the rocket hovering recovery.

But that doesn't mean it can be reused.

Because the rocket engine is disposable.

Liquid oxygen kerosene engines are prone to carbonization and blockage.

The temperature of the liquid hydrogen and liquid oxygen engine is too high, and it basically burns out after one use.

Even if Longhan Technology can successfully recover the engine, it is believed that this engine will not be able to continue to be used.

The only thing that can be reused is the body part of the first stage rocket.

If a rocket has to replace its engine system after each use, then it is not a recyclable rocket at all.

And this so-called recycling is simply selling dog meat on the head of a sheep.

So in the eyes of these NASS experts, Longhan Technology is just a hype gimmick.

Because the recovery of the rocket body part of the first-stage rocket is not rocket recovery at all.

The person in charge of the official unit of the Mi Federation was also relieved to hear this.

But no matter how much it made the Chinese people in the limelight, it still made him very unhappy.

Seeing this, the person in charge of NASS immediately said that he would come out and slap Longhan Technology in the face.

……

The official website of NASS was quick to respond to the news that Longhan Technology had completed the recovery of the rocket.
