NASA's Stunning Close-Up Photos of Comet Hartley 2
Several readers have sent word that NASA's EPOXI spacecraft performed a close approach to comet Hartley 2 yesterday, taking pictures within roughly 700km of the nucleus. Bad Astronomer Phil Plait has a collection of some fantastic photographs, and you can check out a ton of other images on the mission website. The Planetary Society blog put together a neat animation of the flyby. NASA's mission fact sheet (PDF) explains EPOXI's background — it's the supplemental mission of the Deep Impact craft that smashed a small probe into a different comet back in 2005 — and why Hartley 2 was chosen for this flyby (they couldn't find their original target).

EPOXI is the name of the mission (an extension of a previous mission), the spacecraft itself is actually called Deep Impact. Just trying to clear up the ambiguity.

The EPOXI team did a great job, but amazingly most of them are straight back to work after this. The Stardust NExT mission, another repurposing of a used deep space spacecraft is going to be revisiting Temple 1 (which deep impact originally hit) in another 4 months.
Right after the flyby much of the team was in meetings to make sure Stardust gets where it needs to go. Not sure whether it'll be easier or harder though. The comet is larger and less likely to stray too far off course, but the spacecraft itself is a finicky thing that's nearly out of fuel... Should be exciting to see even more pictures like this in a few months.
Just found this animation of the 1986 Giotto fly-by through the tail of Halley. (QuickTime required.) Very cool. Apparently Giotto's still out there and going strong, took a detour through another comet some years later, still does the occasional fly-by near Earth and can be reactivated if there's anything worth looking at. Not bad for a probe that they weren't expecting to survive the Halley encounter.

Space pictures are big. You just won't believe how vastly, hugely, mind-bogglingly big they are. I mean, you may think it takes a long time to down the load of the CSS, but that's just peanuts to space pictures.
