[meteorite-list] Comet impact!

[Dave Harris]

Hi,
..Amazing to see that the copper target that clouted the Comet Tempel 1
kicked out 250,000 tons of water when it collided!
There a great lot of info on the Web on this, but I wonder how this fits in
with how there's so much water on Earth....was it transported via cometary
collisions or the product of chemical reactions (or both, indeed!)?

Can anyone point me towards any good research papers for me to peruse?

The BBC website has a bit of info http://news.bbc.co

Seems that the impact was quite a complex dynamic event with some sort of
secondary subsurface event.

Love to know the thoughts also of some of you astronomers and celestial
dynamicists out there!


Ciao!
