there`s no chance of just giving it a nudge off course and it landing on my house now, is there?



just curious......... :oops:
 
i know,i know,but has anyone actually hit a speeding comet with a lump of copper before? ;)

just for the record,if it does hit me,i told you so,

and if it hits you,dont come running to me complaining, :LOL:
 
Mick,
You've been watching too many dumb, stupid, brainless hollywood movies. NO, the fricken comet won't suddenly turn around and hit the earth just because we shoot it with what amounts to a pellet from a BB-gun fired at a locomotive.

Like, these guys know phizziks and stuff, so relax, ok?

Are you wanting to make an insurance claim or are you just after an excuse to not have to clean the bathroom?
 
That pic looks blurry, they must have forgotten to activate anisotropic filtering on the comet! The antialiasing is nice, tho.
 
Considering the speeds, distances and all the hellish complicated geometry going on, plus that that's quite likely a quick-look (~ engineering) image, it's pretty amazing. :D

Shooting a bullet (spacecraft) , from a bullet (Earth) , to hit a bullet (comet).

Incredible.

epic

Has nasa released any moving imagery of the impact yet? Would be nice to see!

I saw some on the TV last night (big mess it was), but I can't find any accessible via their website. I know a few people involved in other missions which were monitoring the event, it'll be interesting to know what (if anything) they saw.
 
One of the greatest accomplishments of numerical simulation in my lifetime, perhaps *the* most impressive.

Amazing feat, to anyone with an inkling of what a challenging physics problem this is.

The courtcase had me lol for a few though.
