2:45 a.m.!

After a rigorous and careful inspection, all subsystems of the "Kunpeng" O1 cargo spacecraft were in good condition and met the requirements of the test flight.

In the underground master control hall one kilometer away from the take-off and landing field, Qin Tian ordered all technicians and intelligent robots to evacuate.

In just two minutes, all personnel and equipment were evacuated.

2:5o.

Qin Tian ordered the spacecraft's main control intelligent system to start, and after a few seconds, the system was successfully activated and began to enter the self-test.

The communication system is working fine!

The power system is normal!

The powertrain is normal!

The automatic protection system is normal!

……

All subsystems are self-checked, and a large amount of data is transmitted back to the master control hall through large-capacity real-time sharing data links.

More than 100 senior engineers are staring at the LCD screen in front of them, attentive and meticulous.

2:53 a.m.

The self-test of the spacecraft's main control intelligent system was completed, and the flight entered the countdown stage.

Moment!

On the large display screen in the general control hall, a countdown appeared, and the crimson numbers kept tumbling.

At the same time, Qin Tian ordered the plan of the flight mission to be sent to the 'Kunpeng O1' spacecraft, and the data included flight airspace restrictions, degree and altitude restrictions, maneuvers that needed to be completed, and so on.

After the main control system of the spacecraft obtains the mission information, its powerful photonic computing module has completed the unlocking, calculation and issuance of mission instructions in milliseconds.

2:56 a.m.

The spacecraft's power system began to work, and a steady stream of abundant electrical energy was generated through the miniature nuclear reactor, and after a series of treatments such as pressure conversion rectification, it began to be supplied to the power system.

At this time, through the large monitoring screen, you can clearly see the bottom and tail of the spacecraft, as well as the tail vents of other parts are exposed, and the huge tail vent with a diameter of 3 meters really surprised the guests in the hall.

Looking at it this way, everyone suddenly realized that this spaceship was like a dual-type air supremacy fighter, with two very large tail vents in the tail, could this be the rhythm of violent take-off?

Apparently not!

Because the belly of the 'Kunpeng O1' cargo spacecraft also has a motive tail vent, but the size is relatively small.

Some academicians who came to the scene to watch the ceremony immediately whispered to the people next to them that this was a vertical lifting method.

2:58 a.m.

Boom!

There was a loud and dull sound, like thunder in the night sky!

Just when many people thought that the flight failed and that there might have been a big bang.

A spectacular scene appeared.

The 'Kunpeng O1' cargo spacecraft parked at the shooting range suddenly erupted a strong 'air current' from the vent of the engine tail in its abdomen.

The plasma motor uses a strong current to forcibly ionize the pure water carried in the spacecraft, and then under the constraints of a strong magnetic field, the hydroxide element deflagrates to produce high pressure, and finally forms a strong jet thrust, and because this thrust is too strong, it will pass the sound in an instant, so it causes a strong sonic boom effect.

It is precisely because of this that the moment the motive was just activated, a loud bang broke out.

And over time......

An even more spectacular scene has appeared!

The high-temperature 'air current' directly hit the water storage pit in the middle of the take-off and landing field, and a large amount of fresh water stored in it was violently steamed into white gas by the air, and a large amount of water vapor rushed into the sky to form a huge white fog that almost shrouded the spacecraft.

At this time, with the help of the stable thrust of a single plasma motor, the huge 'Kunpeng O1' cargo spacecraft actually slowly took off and landed.

As the spaceship flew higher and higher, a pillar of azure light as strong as an optimus pillar appeared!

This pillar of light is very beautiful and full of fantastic colors.

But it's not science fiction, it's a product of reality, and the scientific definition is called Mach ring.

This is a special phenomenon of air flow, such as jet motor and ram engine, but if it is able to create a sound air flow, it can create a dazzling diamond-shaped standing wave with a strong high air flow, forming a strange landscape where the light and the dark are separated from each other.

This wonderful spectacle is usually only seen when a rocket is launched into the air, or when a fighter jet starts afterburner flight, but the Mach ring with such a huge diameter is really rare in the world.

3 o'clock in the morning.

The 'Kunpeng O1', which is slowly detaching from the surface, and the plasma motor used for vertical take-off and landing, is getting more and more powerful, and the seemingly heavy spacecraft has been 'lifted', and the higher it flies, the more the blue pillar of light that seems to rise into the sky is getting bigger and bigger.

As the altitude climbed, the four sets of hydraulic column feet in the belly of the spacecraft quickly retracted, and the protective partitions were tightly closed.

At the same time, the two main thrust plasma motors were suddenly activated, and in the low-power state, there was only a slight explosion, and soon two azure 'pillars of light' appeared in the tail, and the cargo spacecraft that had risen vertically began to climb obliquely at this time, and finally became faster and faster.

3 o5 a.m.

After the 'Kunpeng O1' took off, it entered a large-diameter spiral climbing state in just five minutes, as if it was taking the science and technology industrial park as the center of the circle, doing a spiral flight with a diameter of nearly 10 kilometers.

Fly higher!

Fly faster!

The 'Kunpeng O1' cargo spacecraft, which was supposed to be extremely heavy, flew quite lightly, like a fighter being tested, flying freely.

3:2o a.m.

The Kunpeng O1, which had been in the air for 15 minutes, did not climb further after climbing to an altitude of 30,000 meters, but began to land slowly.

If a behemoth weighing more than 3,000 tons falls from an altitude of 30,000 meters, it will probably have an explosive impact on the surface of the earth no less than that of a nuclear bomb.

Easy to take, hard to land!

In the entire general control hall, many people were so nervous that they couldn't breathe.

If the Kunpeng O1 gets out of control at this moment, what does that mean?

It means that a spacecraft of more than 3,000 tons will be smashed into or near the science and technology industrial park, and the inertial potential energy of its fall will be equivalent to tens of thousands of tons of explosive yield.

It also means that at this time, Weile Science and Technology City, Science and Technology Industrial Park and even Fukang Airport are in a dangerous state at this moment.

……

Boldness of execution stems from superb skill!

Qin Tian can be immobile and plain as water, so why should others tremble?

Landing!

Everyone's eyes are on the control screen, and through the high optical, radar and infrared capture systems, the 'Kunpeng O1' that is landing is showing a very perfect attitude.

The plasma motor used for take-off and landing constantly passes through the main vent in the abdomen and the small jets in other parts to create a reaction force, adjust the attitude and help the spacecraft slow down the landing.

10,000 meters!

5,000 meters!

Three thousand meters!

When the 'Kunpeng O1' spacecraft became clearer and clearer on the big monitoring screen, its landing was already very slow.

When the altitude was only 5oo meters, the spacecraft had landed less than one meter per second, four hatches had opened on the belly, and four sets of hydraulic column feet had been deployed.

In the slowness visible to the naked eye, the thrust created by the small vent slowly moved the spacecraft towards the sky above the take-off and landing field, making this behemoth seem to complete the attitude fine-tuning with the help of a God's hand, and slowly approached the sky above the take-off and landing field.

2oo meters!

5o meters!

As the ship approached the take-off and landing field, the azure pillar of light from the vent in the ship's belly became weaker and smaller.

Slowly, gently.

The seemingly heavy 'Kunpeng O1' spacecraft finally landed very smoothly.

Suddenly, the entire general control hall was boiling!

Cheers! Screams!

In the midst of the applause, Qin Tian, who pretended to be calm on the surface but was still very nervous in his heart, finally showed a satisfied smile after taking a long breath.

The 'Kunpeng O1' spacecraft flew with great success!

And just when there was a celebration in the general control hall, many people in the world who were secretly paying attention to the movements in the industrial park were stunned one by one.

Not only that, the evacuated people in Fukang County, as well as many surrounding cities and counties, many people saw the peculiar landscape, and many people couldn't help but take pictures with their mobile phones.

For a time, rumors swirled......
