The folks from UnmannedSpaceflight.com have done it again. Daniel Machácek created this wonderful animation from just the five initial images of Hartley 2 that were released by the Deep Impact team immediately following its flyby on November 4, 2010, using Squirlz Morph software. Time in the animation is five times faster than the actual speed [...]

Jets of CO2, and once again, the jets seem oblivious to the direction of the sun.

At first blush, Hartley 2 is very similar to Itakowa, the Asteroid visited by Hayabusa.

Very strange - why is this comet jetting CO2, and how much, if any, water is there?

Is it time to stick a fork in the 'dirty ice ball' model of comets once and for all?

Well, if you watched the second NASA post fly-by press conference that was held two weeks after the event, Mike A'hearn made a valiant attempt to convince the tax-paying public that the dirty snowball comet model is still valid and Comets are primordial Oort cloud material. It was a pretty lame and based on the insightful questions asked in the Q&A section, especially by Emily Lakdawalla of the Planetary Society, it's obvious no one buys the story any longer.
