Fortunately, within the predicted landing range, most of them are oceans and areas with relatively low population density, and the risks are still very controllable.

If it falls in the urban area, it is necessary to organize the evacuation of personnel.

It will cause many chain reactions, and even bring some secondary damage.

After CNSA released the news.

It immediately aroused heated discussions all over the world.

"Damn, I actually predicted such an accurate landing point? This is an out-of-control satellite fragment!"

"Didn't NASA predict where the satellite debris will fall? Can we really predict so accurately?"

"If you don't dare to make it right, you probably won't post it. This is a major issue that concerns the safety of people all over the world. I hope no one will be affected by it."

"I took a look at those places. It shouldn't be a big problem. Places with people are not counted as gathering areas. The possibility of hitting people is very small. But there is an early warning, which can definitely guarantee people's safety to a greater extent. Safety."

at the same time.

Inside NASA, employees are discussing this matter.

"CNSA can really predict where these satellite debris will fall? This is too incredible!"

In NASA's initial announcement, the predicted location of the satellite debris fall was exaggerated to almost half of the earth.

Such a large-scale prediction will not have much effect on people's early warning.

Although CNSA's prediction is later than NASA's, such accuracy is indeed too high.

At this time, they are still paying attention to the trajectory of these satellite fragments and analyzing their subsequent movements.

At this time, a NASA employee suddenly said:

"According to the current trend, the largest satellite fragment may indeed land near this position!"

During the operation of satellite fragments, their mass is continuously reduced due to continuous friction with the atmosphere.

Regarding their trajectory prediction, it is a very complicated matter.

And if the satellite debris is large enough, it will be less affected.

At the employee's words, everyone turned their attention away.

"That's right, their predictions are indeed very likely to be very accurate. The current capabilities of the Huaxia Space Administration are already so powerful..."

At this time, the NASA staff couldn't help but fell into a mood of doubting life.

All along, they have firmly believed that they are the strongest existence in the world's space system.

Even the space systems of other countries are decades behind them.

But this time, they really couldn't figure out how CNSA completed the prediction of where these satellite debris would fall.

after this.

The fragments of the first satellite fell to the surface.

The space systems of various countries are detecting the falling points of the satellite debris.

"The landing point of this satellite fragment is only about 300 meters away from Professor Xu's previous prediction!"

At this time, the staff around Xu You said.

"Oh my God, 300 meters! Normal spacecraft landing missions are only capable of such precision, right?"

The speed of a normal spacecraft landing will be much lower, and the data will be more detailed.

It will be much easier to predict the landing point.

And predict the falling point of a satellite debris that is in an out-of-control state and moves irregularly.

The error of 300 meters is obviously a very incredible data.

"300 meters... It's really close to the error I expected." Xu Youxin said.

In the case of incomplete conditions, such an error is already close to the limit.

According to the statistics of the space agency, the landing point of each satellite fragment is very close to Xu You's predicted location, and the error is all controlled within one kilometer.

Compared with this result, Xu You is more concerned about whether these satellite fragments have hurt some innocent people.

Fortunately, because most of these satellite debris landed in no man's land, coupled with the early warning, no one was killed or injured.

Of course, there were some dangerous moments during this period.

A satellite fragment weighing dozens of kilograms fell only about 50 meters away from a private house.

Fortunately, after receiving the warning notice, they immediately evacuated to a position several kilometers away.

If you don't evacuate in time, even if you don't get hit by satellite debris, you will be scared to death.

Finally, when all the satellite debris has settled, everyone's hanging hearts can finally be put down.

According to the detection of these satellite debris landing points by the space systems of various countries, it proves that CNSA's prediction is very accurate.

"Fortunately, no one was injured in the end. Our space agency is really powerful. We can predict things that even NASA can't predict so accurately."

"It is said that a satellite fragment landed near a private house. Fortunately, they evacuated in advance. If they did not evacuate, there might be a serious accident."

"Don't say whether it hits or not, you can be scared to death. But what is the cause of this accident, there is no clear statement yet."

At this time, NASA Director Robert was discussing this matter with several space agency experts.

"Why is CNSA able to predict the landing point of the satellite debris so accurately? We actually gave such an outrageous range from 58 degrees north latitude to 58 degrees south latitude. This is really a joke for the whole world!"

The gap between the two prediction ranges is already several orders of magnitude apart.

"Director Robert, this kind of prediction is indeed very difficult, there are too many factors that are affected, and many data are unavailable. Unless..."

"Unless what?" Robert asked, frowning.

"Unless they install an annunciator on this satellite, they can monitor various data about this satellite in real time. Of course, it must be ensured that there will be an annunciator on each satellite fragment."

After hearing this, Robert sneered and said:

"You don't believe it yourself, do you?"

"Yes, like we still can't believe it at this time, they really accurately predicted where these satellite debris will fall."

"I don't care so much. Since they can do it, we must do it too. They have always been our followers, and we must not let them go ahead of us."

"Director Robert, it is still difficult for us to analyze how they judged the location of these satellite debris just by relying on these landing points. This is like a difficult problem, only one answer is given, and there is no process of solving the problem. .We'd better get their full predictive model if we can."
