[Well, close to it, anyway.](http://www.space.com/spacewatch/050603_deep_impact.html)

For some reason, I’m reminded of that _Far Side_ cartoon of the moonmen watching a nuclear war on Earth and going, “Ooooooh!”

Of course, [this guy](http://www.brianmay.com/brian/brianssb/brianssbjun05a.html) thinks that it’ll destroy the comet and doom us all!

> Thanks Noah … yes, I realize that it is HOPED that the whole comet will not be affected, but I am 99 per cent sure that there is no guarantee of this. Who could be that sure, when no-one even knows the interior morphology of the object. Suppose it were one giant crystalline structure ? What an irreversible mess the projectile would make in this situation.

My only question to the team behind this is … “Are you really sure you are behaving responsibly here ? Can’t you wait until we know more ? Until we can be a bit more clever and attempt a landing ?” I’m really personally outraged by this. There are those who think that even life on the Earth may have originated from micro-organisms on such a comet …
