Comet Hartley 2's nucleus

COMET ENCOUNTER UPDATE: NASA's Deep Impact (EPOXI) probe has just completed its 435 mile flyby of Comet Hartley 2's nucleus. The spacecraft has turned its high-gain antenna toward Earth and data are being transmitted to mission control at JPL. The first raw images have just arrived and, even without processing, they are spectacular:

The first five close-up images: #1, #2, #3, #4, #5 

A press conference will be held this afternoon at 4 pm EDT to discuss the results and to reveal even higher-resolution images. Tune into NASA TV to follow events live.
