Chapter 313: Really? I don't believe it
Fortunately, the predicted landing points are mostly oceans and areas with relatively low population density, so the risks are still very controllable.
If it falls in the urban area, it will be necessary to organize the evacuation of personnel.
It will cause many chain reactions and even bring some secondary damage.
After CNSA released this news.
It immediately sparked heated discussions around the world.
"Holy crap, they actually predicted the landing point so accurately? This is the debris of an out-of-control satellite!"
"Didn't NASA predict where the satellite debris would land? Can we really predict it so accurately?"
"If they didn't dare to make a precise call, they probably wouldn't have sent it out. This is a major matter that concerns the safety of people all over the world. I hope no one will be affected by it."
"I looked at those locations and it shouldn't be a big problem. The places with people are not considered gathering areas, so the possibility of hitting people is very small. However, having an early warning will definitely ensure people's safety to a greater extent."
at the same time.
Inside NASA, employees are discussing the matter.
“Can CNSA really predict where these satellite fragments will land? This is incredible!”
In NASA's initial announcement, the predicted landing location of satellite debris was so exaggerated that it almost occupied half of the earth.
Such a large-scale forecast will not have much effect on warning people.
Although CNSA's prediction is a little later than NASA's, its accuracy is indeed too high.
At this time, they are still paying attention to the movement trajectory of these satellite fragments and analyzing their subsequent movements.
At this time, a NASA employee suddenly said:
"According to the current trend, this largest satellite fragment may indeed land near this location!"
As satellite fragments move, their mass continues to decrease due to constant friction with the atmosphere.
Predicting their trajectories is a very complicated matter.
If the satellite fragment is large enough, the impact will be smaller.
After hearing what the employee said, everyone shifted their attention.
"Yes, their predictions are very likely to be very accurate. The current capabilities of the Chinese Space Agency are surprisingly so powerful..."
At this time, NASA staff couldn't help but fall into a state of doubt about life.
They have always firmly believed that they are the strongest in the world's aerospace system.
Even the aerospace systems of other countries are decades behind them.
But this time, they really couldn't figure out how CNSA completed the prediction of the landing points of these satellite debris.
After this.
The first satellite fragment fell to the surface.
The space systems of various countries are detecting the landing points of satellite debris.
"The landing point of this satellite debris is only about 300 meters different from Professor Xu's previous prediction!"
At this time, the staff beside Xu You said.
"Oh my god, 300 meters! Isn't this the accuracy for a normal spacecraft landing mission?"
During a normal spacecraft landing, the speed will be relatively much lower and all data will be more detailed.
It will be much easier to predict the landing point.
And predicting the landing point of a satellite fragment that is out of control and moving irregularly.
An error of 300 meters is obviously an incredible data.
"300 meters...it's indeed quite close to the error I expected." Xu Youxin said.
Under incomplete conditions, such an error is close to the limit.
According to statistics from the space agency, the landing point of each subsequent satellite fragment was very close to Xu You's predicted location, and the error was all controlled within one kilometer.
Compared with this result, Xu You was more concerned about whether these satellite fragments would hurt some innocent people.
Fortunately, because most of the satellite fragments landed in uninhabited areas and there were early warnings, no casualties were reported.
Of course, there were some dangerous moments during this period.
A satellite fragment weighing dozens of kilograms landed only about 50 meters away from a residential building.
Fortunately, after receiving the early warning, they immediately evacuated to a location several kilometers away.
If you don't evacuate in time, even if you are not hit by satellite debris, you will be scared to death.
Finally, when all the satellite debris had settled, everyone could finally put their minds at ease.
Based on the detection of the landing points of these satellite debris by space systems of various countries, it is proved that CNSA's prediction is very accurate.
"Fortunately, no one was hurt in the end. Our space agency is really amazing. We can predict things so accurately that even NASA can't predict them."
"It is said that a satellite fragment landed near a residential building. Fortunately, they evacuated in advance. If they hadn't, there might have been a serious accident."
"Don't even mention whether it hits or not. It's enough to scare people to death. But there's no clear explanation as to what caused this accident."
At this time, NASA Administrator Robert was discussing this matter with several experts from the space agency.
"Why can CNSA predict the landing point of satellite debris so accurately? We actually gave such an outrageous range of 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.
"Director Robert, this kind of prediction is indeed very difficult. There are too many influencing factors, and a lot of data is unavailable. Unless..."
"Unless what?" Robert asked, frowning.
"Unless they install a signal device on the satellite, they can monitor all data about the satellite in real time. Of course, they also have to ensure that there is a signal device on each satellite fragment."
After hearing this, Robert sneered:
"You don't even believe what I said, do you?"
"Yes, as much as we still can't believe it, they really predicted the landing points of these satellite fragments accurately."
"I don't care. Since they can do it, we must do it too. They have always been our followers, and we must never let them get ahead of us."
"Director Robert, it is still difficult for us to analyze how they determined the landing points of these satellite fragments based on these landing points alone. It is like a difficult problem that only gives one answer but no solution process. If possible, we'd better get their complete prediction model."
