Remember this ...

'When NASA's Deep Impact mission ploughed into comet 9P/Tempel 1 on
July 4th of this year, the giant telescopes on Mauna Kea had a unique
view of the massive cloud of dust, gas and ice expelled during the
collision. See previous Gemini release on observations here.cache ...'


They haven't answered the crucial question. Has the comet been knocked
sufficiently off course? Will it now miss the Earth?


It wasn't going to hit Earth.

Natural encounters with Jupiter and other perturbations have a
far greater effect than Deep Impact. In fact normal outgassing
from the comet will probably have a larger effect.
