That's interesting Wally.
Will this projectile hold any instrumentality to film or sense anything?

Or does it contain high explosives?
Or even better a 100 megaton nuclear device?

Well.. one day we may need to do this, and it would be a great opportunity to do some comet demolition practice - no?

Launching this December, "Deep Impact", due to fire a 820 pound projectile
into the comet, in July 2005, to give us a look at the composition.
Predictions are that the comet will brighten to about 5th magnitude, so
you'll still need a scope or binoculars, if it hits as predicted night-time
Australian time.

I'll make a quick prediction. The chicken littles of the world, and the
conspiracy nuts will suddenly become aware of this mission, and get all
twitterpated about it.
Some will worry that bits of the comet might break off and hit the Earth,
and try to stop the mission even after launch. Others will think NASA has
"known all along that this comet was heading for Earth, and this is designed
to stop it", conveniently ignoring both the ephemeris of the comet, and the
energy being released by the projectile.

Hoaxland and McCanney, and the Millennium Group will continue to claim that
comets are hot, electrified bodies, and not cold, regardless of
spectrographic evidence to the contrary.

Anyway, I'm looking forward to this, because the display should be awesome.
