I mean, they basically pulled off a test-fire of Armageddon without having to use drills, roughnecks, and Ben Affleck in space, but hey. Sneer away.

And I am, I'd wager you didn't say much about Iraq and Afghanistan circa 2004.

I believe I'd hide for a few days after your failed forecast from yesterday.
Not enough water to strengthen, eh?

NASA / asteroid rocket / target practice: (?) Nuke tip (?)
Sep 27, 2022, 6:47 PM
|
|
Expensive target practice for if (when?) the 'killer asteroid' is on a trajectory towards Earth. IMO, if we're going to waste money, then this is one of few places where I'd recommend wasting it.
Going a bit off topic ... here goes:
Did the rocket have a nuclear tip on it (i.e., to see if the nuke would change the trajectory of the target asteroid)?
(*) Maybe the nuke tip for target practice isn't a good idea; given our luck it would change the trajectory of the 'target practice' asteroid towards Earth.

asteroids hit the earth once every 500k-100 million years, the latter big enough to wipe us off the planet. Not to go all solos, but there is likely one that just drifted away from the Kiper belt and is playing a game of Plinko into our solar system, or why would they bother?

what would a nuclear tip do?

put a little hole in it?
The purpose is to change trajectory. Conservation of momentum not a lot of mass but 14,000 mph so it's a lot of momentum transferred as long as you hit it square and the spacecraft loses most of its momentum.

Re: what would a nuclear tip do?

If the (big) nuclear tip did not detonate until it hit the surface, then the equal but opposite reaction (i.e., the same force by which a rocket moves in the gas-less void of outer space) of a nuclear explosion would contribute to nudging the asteroid towards a slightly different trajectory.
A not insignificant percentage of the energy from the incoming rocket (sans nuclear tip) would be dissipated from the point of impact by the scattering in all directions of matter which got dislodged at the surface of the asteroid. It's not as if all of the energy from the incoming rocket would be conveyed towards moving the asteroid.

What's amusing about your complaint
Sep 28, 2022, 8:43 AM
|

Is that this was a test run for taking out actual threat asteroids that could wipe out our planet.
Which reminds me of the movie Don't Look Up. You'd definitely be one of those people denying the existence of the asteroid even as it barreled into view.
