NASA simulates an asteroid headed for Earth, and there’s bad news for us.



In movies, games, or TV shows about asteroid disasters heading to Earth, the news is often shocking. Depending on the specifics of the story, the world̵

7;s population can range from a few days to a few months.To prepare for the inevitable, things tend to look terrifying. But more often than not, humanity can pull rabbits from their hats and come up with plans to save billions of lives. But that’s fiction, and although humanity has some incredible technology, But there is also a chance that we won’t be as lucky as our partner. In fact, more or less a recent simulation experiment conducted by NASA proves that an asteroid headed for Earth spells its doom, even though we have six months to prepare.

During the annual planetary defense conference, scientists from various space agencies participated in an emergency response scenario where a fictitious asteroid called 2021 PDC was bound to Earth. Scientists say they have six months to plan, and over the course of several days, the future begins to look incredibly bleak.

As new information began to pour in, it became clear that the asteroid was about to affect Europe. But tracing the path of asteroids is only part of the job. The actual test simulates a response that will save lives. The participants considered many options, including trying to push the asteroid off course. But it is too close to the world to have an effect. In addition, the scientists noted that “The force required to move an asteroid in 2021 PDC out of its path of collision with Earth is so common that it is at risk of destroying the asteroid – potentially creating a large number of large chunks that could potentially destroy the asteroid. May affect the world “

Scientists are also considering the use of nuclear explosives to destroy, or at least reduce the chance of large impacts that can severely pass through the Earth’s atmosphere. Unfortunately, the team faces the fact that “international law cuts off the use of nuclear weapons in space” means that there is little they can do in such a short notice.

“The Space Mission Planning and Advisory Group (SMPAG) has concluded that no space mission can be launched to asteroid 2021 PDC in time to deflect or destroy it,” the ESA noted in the exercise notes.

The fictitious asteroid struck the Czech Republic near the border with Germany and Austria. The final report before the impact narrowed the impact location to 23 kilometers and the strike time to be within one second. An asteroid, which is only 100 meters in diameter, inflicts devastating damage over an area of ​​300 km in diameter, increasing the damage as you approach the impact point.

Of course, this is just a simulation, so it is impossible to say how accurate the global response will be in six months compared to just a few days during the conference. If the nuclear response is encouraged by scientists and it looks like it might work, you have to imagine that anti-active international law will be eased and humanity will do whatever it takes to prevent it. At least that’s hope.
