QUOTE C. Jones announced that the press conference is postponed to 1pm on Tuesday Feb 15. The closest images should be received in the morning. They don’t know why the data were sent/saved this way yet.

Do we know if the rotational phase seen by Stardust matched any seen by Deep Impact's HRI instrument during approach? Since the latter is a much higher res instrument, it actually picked up a good bit of rotation on the way in, as can be seen here.
For fun I tried matching one of the earlier HRI frames to the first good Stardust image. Looks like a slightly earlier snapshot than I picked would make a better fit, bit it was at too low a resolution. HRI image magnified some 200 % and rotated to "fit". Some vaguely similar albedo patterns there. -------------------- |

My impression based on your animation is that the HRI image should be rotated 90 degrees clockwise to match the new view.

I rotated it slightly over 70 degrees clockwise. Close but no cigar?

No, I mean the comparison as you presented it just above, still needs a 90 clockwise rotation. The bright spot on the right of your HRI image is the bottom point of the Stardust image. If you watch your animation zoomed in, you can see how the motion carries that bright spot down to the bottom of the nucleus, while the area that will become the one you're trying to match rotates into view.

Multiple new images, much closer to the comet.

They're beautiful - utterly beautiful - I wasn't expecting the camera to perform quite so well.

Just catching up with this 'cos I've been at work all day until now, but wow, what an achievement. And well done Doug for all your hard work on this, too.
Amazing times we live in. Amazing times... -------------------- |

Wow! I had honestly been expecting images much less clear than these. Looks like this mission will pay off nicely.

I'm impressed at the image quality too.
A couple closer images. http://www.jpl.nasa.gov/images/stardust/st.../n30033te01.jpg http://www.jpl.nasa.gov/images/stardust/st.../n30034te01.jpg -------------------- -- Hungry4info (Sirius_Alpha)

My best guess for the impact site (based on looking at the Deep Impact images). That crater is in the DI approach images, so it can't be it. -------------------- |

You're right, I got my orientation of the surface features wrong. It should be somewhere to the left of the circular crater.
