Genius is just the threshold for me!

"It's burned out."

As Lin Dong watched the satellite disappear, he quickly estimated that at that crash angle, the entire satellite would be burned up by the atmosphere.

of course.

Because the trajectory and the firing position were calculated.

Even if it doesn't burn completely, the remaining debris will travel south-southeast and eventually fall into the South China Sea.

boom--

After Lin Dong finished speaking, he checked the distance to the second satellite and quickly entered a series of commands.

HotSpicy No. 5's intelligent system automatically activated, changing its flight direction and heading west.

"The second satellite is coming..."

Watching the movements of the "Hot Spot" satellite, Wang Xingguo suddenly glanced at its orbit and trajectory, and exclaimed in surprise, as if he had discovered something: "Xiao Dong, this satellite's orbit runs from west to east. If we shoot it down... it will crash all the way from Chengdu to the East China Sea, and half the country will be able to see this man-made meteor!"

"Isn't that very risky?"

Upon hearing this, Jiao You's expression changed to one of alarm: "Some satellites have components that are difficult to burn up. If they don't burn up completely in the atmosphere, wouldn't they possibly crash into a coastal area?"

A satellite inevitably contains some high-temperature resistant and sturdy metals, which are difficult to be completely burned off by the atmosphere.

For example, nickel-based high-temperature resistant metals for engines, titanium alloy fuel tanks and high-pressure gas cylinders, including the gyro momentum wheels of satellites, will almost always leave some debris if the satellite is even slightly large.

The satellite's trajectory is currently moving from west to east, traversing the entire country's territory. If debris were to fall, it could very well hit densely populated areas on the ground.

"Uncle Jiao, this 24-hour SAR reconnaissance satellite weighs 3.2 tons, and there will be about 260 to 450 kilograms of debris that will not be completely burned away."

But the remaining unburnt wreckage won't fall domestically because its weight and crash altitude are too great..."

Lin Dong smiled and said, "The straight-line distance from Chengdu to the eastern coast is 1600 kilometers, but this satellite is quite heavy, and it lost control at an altitude of over 400 kilometers and began to fall."

Ultimately, most of the debris fell within a range of 2800 to 3500 kilometers from Chengdu, which is exactly within the high seas of the East China Sea.

Extremely small debris could travel over 5000 kilometers, but it certainly wouldn't be within the reach of coastal cities.

Satellite or rocket debris falling to the ground could potentially hit people; this is an objective risk.

However, in more than half a century of human spaceflight, only one person has been hit on the shoulder by debris, but no one has been killed by space debris. This is also objective data.

Decades of observation and research have led to a rough estimate of the distribution range of spacecraft crashes.

Depending on altitude, volume, and weight, the longitudinal range at the time of the crash ranges from 800 kilometers to several thousand kilometers, while the lateral distance ranges from tens of kilometers to a thousand kilometers.

The higher the altitude, the longer the crash time, the larger the volume and weight, the less completely the parts disintegrate, and the farther the distance the object will fly during the crash.

For example, the Tiangong-1 space station in its previous life, weighing 8.5 tons, underwent controlled reentry and crashed at an altitude of 132 kilometers, with its entire dispersion area reaching an astonishing range of 1200 kilometers horizontally and 6000 kilometers vertically.

Ninety-five percent of the debris landed within a range of 3800 to 4500 kilometers, almost perfectly following plan as it fell into the South Pacific Ocean...

"It's fine as long as you don't know how."

Jiao You felt relieved after hearing this explanation.

beep!

At this moment, the camera captured the trace of the second satellite rising above the horizon, and soon, the laser measurement of Hot 5 also locked the satellite's trajectory a thousand kilometers ahead of schedule.

呲——

The speakers emitted a simulated laser emission sound, and the satellite on the screen instantly reflected a bright light, vaporizing the aluminum foil protective layer on its surface.

The laser continued to track and irradiate for two seconds, then a burst of high-pressure gas was ejected, causing the entire satellite to suddenly lose its attitude and begin to spin and tumble, slowing down and decreasing its altitude...

"hiss!"

Upon seeing this, Wang Xingguo gasped in amazement and exclaimed, "That second shot was so much cleaner and more decisive!"

During the first shot, the automatic system still needed to probe, measure, and adjust the lock little by little.

But this time, the system directly controlled the flight direction of the Hot Spot to make an angled collision with the satellite, while the laser measured the precise trajectory and distance, and the next moment it was tracking and irradiating at full power.

The entire process was smooth and seamless, without the slightest bit of hassle. Before anyone could react, the satellite had already been destroyed and crashed.

"Intelligent algorithms have a relatively high learning efficiency."

Lin Dong watched the crash trajectory tracked by the camera for several seconds, then quickly calculated in his mind for a few seconds to confirm that the wreckage would crash into the high seas as initially calculated. He then picked up the keyboard and quickly entered the command code for returning to base.

"Uncle Xu, Godfather, Uncle Jiao..."

Lin Dong watched as the Hot No. 5 and the Photography No. 5 began their return journey on the flight interface. After checking the backend data and confirming that there were no problems, he turned to Wang Xingguo and the others and said.

"When Hot No. 5 and the filming aircraft return, please send them back to the hangar for me... Just send me a copy of the flight damage and inspection report, as well as the flight data."

"where are you going?"

Xu Ziming was stunned for a moment when he heard what Lin Dong had told him, and subconsciously asked a question.

"Watching shooting stars with Qingling!"

Lin Dong tossed out a sentence, then grabbed Xu Qingling's hand, quickly stood up, and shouted as he walked outside, "Hurry up, we'll be flying over soon."

"oops--"

Xu Qingling exclaimed in surprise, then immediately caught up, her long hair flowing and her dress swaying, her face beaming with joy, "Dongdong, we haven't crashed into the atmosphere yet..."

"We'll cross the Carmen line in a little over a minute... then we'll be able to see it," Lin Dong replied quickly.

"..."

Xu Ziming watched the two of them run out hand in hand in front of him, and then heard their cheers. His expression darkened instantly.

"Hahaha……"

Seeing this, Wang Xingguo couldn't help but laugh and said, "Ziming, what an amazing son-in-law! You don't even need to wait for celestial phenomena to show a shooting star; you just create one yourself..."

"roll!"

Xu Ziming cursed, but his gaze involuntarily turned to the window, to the clear, crisp October sky that was almost cloudless as it approached three o'clock in the afternoon.

call--

After waiting for about a minute, suddenly, a bright star appeared in the sky.

"They're here!"

Lin Dong cheered, stood by the test flight field, took Xu Qingling's hand, and looked up at the stars in the sky.

"I saw it..."

Xu Qingling cheered with equal delight, her eyes fixed on the man-made star.

As the two watched, the stars in the sky grew brighter and brighter, tracing a bright path against the blue sky background and leaving a faint white trail as they flew straight eastward...

After flying for more than twenty seconds, we left the sky overhead and entered the eastern horizon.

At this time.

The entire star glowed with a bright yellow light, then disintegrated and shattered in the sky, transforming into dozens of bright yellow fireballs, like beams of light from outer space, streaking across the sky and disappearing on the eastern horizon...

"It's a pity, we can only see a portion of the fireball from Chengdu..."

Lin Dong watched the entire process of this reconnaissance satellite, which cost over a billion yuan, illuminate the artificial meteor as it sank below the horizon. He said with a touch of regret, "Next time, if we have the chance, we should go to the eastern coast and release meteors again. That way, we can see the whole thing..."

Because of the Earth's curvature, only a portion of such a fireball spanning thousands of kilometers is destined to be visible.

They launched a satellite in the southwest region, so only the initial part can be seen in the southwest, while the remaining, most spectacular part can be viewed from the eastern coastal area.

"It's ready..."

Xu Qingling held Lin Dong's hand, looked at his face, and her eyes almost curved into crescents: "It's enough for us to see it at home. We'll leave the rest for them to see..."

Rumble!

As soon as Xu Qingling finished speaking, a series of booming sounds rang out in the sky.

A dark gray aircraft, gleaming with a metallic sheen in the sunlight, fell from the sky and landed at the test site. After gliding for more than 100 meters, it braked and slowed down, coming to a steady stop at the entrance of Xu Ziming's final assembly workshop.

hum-

The engine's intake fan blades started up again.

A high-powered electric motor drives the engine, and precise control of the engine's thrust ratio propels the aircraft into the workshop after a turn.

As the Hot Air entered the hangar, another unmanned aerial vehicle appeared in the sky.

The aircraft, equipped with an exaggeratedly long-range tracking camera, landed at the test site, taxied, and stopped at the workshop entrance before being precisely driven into the hangar by electric propulsion...

"Dongdong!"

Xu Qingling watched Hot No. 5 and the filming number return to the hangar, when suddenly something occurred to her, and she turned and called out to Lin Dong.

"What's wrong?" Lin Dong turned his head curiously.

"It's nothing."

Xu Qingling shook her head, gently pried Lin Dong's fingers apart one by one, then interlocked her own fingers with his, and whispered, "Once the project is finished, let's go see what the newly built theme park at Xingdong Company looks like?"

"Sure, I promised you two years ago."

Lin Dong nodded: "I'll call you when the time comes, and I'll make the arrangements..."

"it is good."

Xu Qingling immediately responded happily, and the two walked hand in hand towards the residential compound: "Do you think aliens really exist in this world?"

"Maybe."

Lin Dong chuckled and told a lame joke: "It's said that aliens live on the moon. The reason the Americans developed so rapidly in the last century was because they used Apollo to smash aliens' heads and force them to reveal a bunch of alien technology."

Ok.

Twelve years from now, there will be another version of this lame joke.

That's why China's development has been so rapid in the future—it's because during the moon landing, they burned the aliens' heads with cigarette butts and extracted a bunch of alien technology from them.

"this……"

Xu Qingling was taken aback: "If someone could be hit on the head by the Apollo spacecraft, would they still be considered an alien?"

"Who knows, maybe these aliens are native to the solar system and have never left it, never seen the universe..."

"Okay—" Xu Qingling was finally convinced.
