Well - impactor TCM 1 went well - <0.3% error and it's on course for a nominal impact time. PI has suggested that the comet is Banana shaped and we're going to hit the end of it which looks a little triangular

Here I've tinkered with the brightness to see the terminator area better.
A lovely new world! Despite what A'Hearn said I think this is quite a lot like Borrelly in many respects - but we see it a lot better. It's VERY different from the weird Comet Wild-2, with its amazing spiky hills and scarps. The top is rotating towards us, meaning cometary north is to the right (the new IAU definition of north on objects like these). Note how the two smooth patches give the appearance of lying in the the central portions of broad shallow depressions. A proper shape model will be made later, so I hope it confirms this. Despite VP's comments, I don't have a problem interpreting the circular features as impact craters, though presumably if the artificial impact tells us anything it should be that natural impacts will trigger venting and the crater will evolve rapidly. But the dark shading VP mentions looks to me like the outer part of the rim on one side, and the inner part of the rim on the opposite side... it looks OK as a crater to me. Well, we'll see... I have my opinions, but I've been wrong before. (just ask my kids!) Phil -------------------- ... because the Solar System ain't gonna map itself.

Let me get this straight: they're not sure if they see the crater? The whole point of the mission was to look inside the crater to see the interior of the nucleus! Don't get me wrong, the nucleus photos are great and the impact photos are absolutely spectacular, but what about the science?

I don't think it's that bad- the main way they planned to see what was in the crater was to watch that stuff being blasted out into space, rather than look at what was left behind in the hole- they will have lots of data on what's inside the comet. But seeing the crater would tell a great deal about the strength of the nucleus and about impacts in general. If they can't see the crater through the the plume, it will be a disappointment, but not a disaster. |

Although it seems like the majority of the imaged are still being downlinked. -------------------- ----------------------------------------------

Trying to make sure I understand the geometry of the image: in the lookback image, the really bright spot is the sun, right? (As opposed to the plume from the impact)
