Lawrence Livermore National Lab simulates the deflection of a nuclear “Armageddon” asteroid
As if last years fabulous Double Asteroid Redirect Test cooking A Satellite ball In A asteroid was not enough, NOW researchers are TO DO detailed simulation of THE nuclear DETOUR scenario considered In 1998 space disaster movie “Armageddon. »
HAS Laurent Livermore National Laboratory, A team directed by Married Burkey (above) present A paper that moves THE ball Before on What East In reality A enough active area of research. As they indicate out, using A Satellite as A missile is not it always practical, And In do detonating A nuclear explosive device as close as possible has THE incoming object East potentially OUR best move.
THE issue East that A nuclear DETOUR would be need has be do In A very accurate path Or other he could lead (as he did In "Armageddon") has parts of THE asteroid struck Earth anyway. This could result In THE widespread devastation scenario considered In THE 1998 space disaster movie "Deep Impact. »
As Burkey And Al explain In their paper published In THE Planetary Science Log:
Even When A asteroid complex structure And inhomogeneous material properties are together next to And THE object East approximated as A uniform sphere, THE pure width of THE required physics present difficulties.
Fully simulation THE energy deposition requires particle transportation In A complete radiation-hydrodynamics coded team with detailed material models And East very computer-wise Dear, Since THE time not must be little has model THE interaction of THE radiation with THE asteroid. He can take weeks has run A simulation even on 200-300 Processors.
No Single coded can encompass all ten orders of magnitude while correctly accounting For all of THE different physics packages, SO sharing THE issue In steps And discount disabled THE progression has codes that blanket THE relevant physics of THE following scene East desirable.
And as most of THE energy product by A nuclear blast East X-rays (which Today I learned), simulation how they propagate And initially interact with A asteroid surface East A critical stage. This paper provides A more complete And Understood simulation of such A effort, "to use A complete rad-hydro simulation team with evolution opacities, which Also activated he has be THE First of all complete effort has explore THE high fluency diet Or A disruption style mitigation assignment would be function. »
In other words, It is among THE First of all has Really look has What would be In fact arrive, microsecond by microsecond, if We nuclear A asteroid. And Since It is What You came here For, he looks as this:

That all takes place on A Single second, as You can see Since THE time rating (1e+06 microseconds East A million of them, manufacturing up A complete second).
THE paper doesn't go beyond It is provisional results, which are basically that This simulation method East accurate enough that We can rely on on he For A more large scale study of nuclear asteroid attack:
