    What an oddly shaped comet nucleus! It is getting more and more exciting the closer you get to the comet. Thnak you for sharing this pictures with us! I am very anxious to see the next one with even more details!

  • Glen says:

    What interpolation method is used to process the image?

  • Gianfranco says:

    Two craters!

  • Phil Stooke says:

    No, two image artifacts.

  • Andrew R Brown says:

    I knew the NavCam would not disappoint and have been proven correct.

    These are superb images, the NavCam is an incredible camera in it’s own right.

    1,024 by 1,024 pixels pixels in a five degree wide view.

    The nucleus of 67P G-G is smaller than many mountains, is also much smaller than both of the Mars moons, Phobos and Deimos and yet from 1,933 KM away, the shape of the nucleus is clearly visible and surface details are showing.

    Yes I think they are both craters and I think some other smaller craters are on the limit of being seeable.

    Tomorrow’s OSIRIS update will show a much higher resolution view, but these NavCam images are amazing also, and the nucleus will balloon in size in the frame.

    Looks like possibly two craters . One forming an eye for the Duck 🙂

  • Donald Q says:

    Incredible. The exploration of this comet will be AWESOME. I cannot wait for the lander, Philae, to touch down and I cannot wait for the comet’s closest approach to the Sun.

    kometi kusanaq!

  • Nicolas says:

    Just one week! Can’t wait! Thanks a lot for all these beautiful images! I’m more afraid about the weak link between nucleus every day

  • Hannes says:

    If landing of Rosetta is successfull, the comet hopefully belongs to Europe then? Or do we have to put a EU flag into the ground 😉

  • Mark Roworth says:

    This is so exciting. It really is.

    Am wondering if the two craters are actually a result of the interpolation to create the image at this size. I used to play around with images and averaging some time ago at uni and you used to get aberations like this that weren’t actually there.

    Anyway, wait and see. It’s just like Christmas!
