quote:

NASA has held a tabletop exercise this week in which planetary defence officials pretend an asteroid is about to hit the Earth in order to see how key players respond.

The hypothetical impact scenario has been run all through this week from April 26 at the 7th International Academy of Astronautics Planetary Defence Conference 2021.



quote:

Throughout the week, CNEOS has been releasing new information each day to conference participants, skipping through months at a time as more and more information about the asteroid is "discovered."

At the start of the scenario, a pretend asteroid was "discovered" on April 19 this year, given the fictional name 2021 PDC. Using impact monitoring systems, scientists agreed the impact will take place in six months' time, though the probability was initially 1 in 2,500. By April 26, the chance of impact had been revised upwards to 5 percent. The pretend asteroid 2021 PDC is estimated to be between 35 and 700 meters in size.


Wargame...or real scenario dressed up as a wargame to reduce the likelihood of panic?

Either way, we need to get Bruce Willis on the phone.

Just like Johns Hopkins wargamed a corona virus outbreak in fall of 2019?

We’re screwed.

I hope it lands on my house. I'd rather go out immediately than try and survive a massive global cool down.

If an asteroid was going to be hitting the earth, the scariest thing wouldn't be what it did to the planet.

The scariest thing would be what humans would do to other humans as the asteroid made its way here.

Frickin NASA LARPers seem like they’d be even weirder than regular LARPers

Colonize the Moon. Use it as a lifeboat until the dust settles after the impact on Earth. Keep stores of seeds and cryogenically frozen livestock embryos to restock the Earth with sources of food.

Why wouldn’t you just do all of those things more easily and cheaply on Earth?

Don't listen to him, Mr. Asteroid. That's a perfectly normal size.

Superpower A launches a mission to divert the asteroid for the good of humanity but really nudges it to land squarely on superpower B.

It’s more thrust to weight ratio that’s important

700 meters is close to half a mile wide. Pretty decent size.
Will cause global effects for sure. Supposedly a half mile wide asteroid can demolish an area the size of West Virginia.

My thing is:With all these geniuses they can't figure out the size of the asteroid and their best guess is between 35 and 700 meters.

So it's either one size or 20 times that size, we're not sure.
