a newer picture in two version, first the unprocessed one:



and now the enhanced version:



NAVCAM image of Comet 67P/C-G taken on 25 June 2015, 168 km from the comet centre.
Credits: ESA/Rosetta/NAVCAM – CC BY-SA IGO 3.0

In this orientation the unmistakable outline of the Hatmehit depression on the comet’s small lobe can be seen towards the ‘top’ of the scene. In the foreground, the ‘Nut’ depression is visible while Serqet is cast in dappled shadow.
Much of the large lobe is obscured by shadow, but a glimpse of Seth can just be seen on the bottom left with Babi in the distance.
On the right hand side a sharp transition between Seth and Anubis is seen, with a small patch of Atum just catching the sunlight at bottom right. The section in the background comprises areas previously in shadow and as such the boundaries are less well defined.

one month to go to perihelion, from esa:



The orbit of Comet 67P/Churyumov–Gerasimenko and its approximate location around perihelion, the closest the comet gets to the Sun. The positions of the planets are correct for 13 August 2015.

esa has just released some close-ups:



Title Anubis close-up
Released 15/07/2015 3:00 pm
Copyright ESA/Rosetta/MPS for OSIRIS Team MPS/UPD/LAM/IAA/SSO/INTA/UPM/DASP/IDA

Close-up of the smooth-textured Anubis region on the large lobe of Comet 67P/Churyumov–Gerasimenko and the surrounding rough Atum region. The image was taken on 5 September 2014 from a distance of about 40 km from the surface.




Title Anuket to Ma’at
Released 15/07/2015 3:00 pm
Copyright ESA/Rosetta/MPS for OSIRIS Team MPS/UPD/LAM/IAA/SSO/INTA/UPM/DASP/IDA

Close-up view of the surface of Comet 67P/Churyumov–Gerasimenko in the Anuket region, close to Ma’at, on the comet’s small lobe. The image shows relatively smooth dust-covered patches covering more rugged terrain, which is exposed in places.
The image was taken by Rosetta’s OSIRIS narrow-angle camera on 14 October 2014 when the spacecraft was just 8.5 km from the comet’s surface.




Title Hathor and Anuket
Released 15/07/2015 3:00 pm
Copyright ESA/Rosetta/MPS for OSIRIS Team MPS/UPD/LAM/IAA/SSO/INTA/UPM/DASP/IDA

This OSIRIS narrow-angle camera image highlights the boundary between the Hathor and Anuket regions on Comet 67P/Churyumov–Gerasimenko’s small lobe. Parts of the large lobe can be seen in the foreground.
The image was taken on 13 September 2014, when Rosetta was about 28 km from the surface of the comet.

OSIRIS images showing Comet 67P/Churyumov–Gerasimenko in different orientations. Rotation axes have been added; in the middle two panels the rotation axis is almost toward the viewer, that is, providing a north polar view.
Right: the same images with regional boundaries and nomenclature added.

This image set highlights the boundaries between Anubis, Atum and Seth on the large lobe, and the transition between the neck and Anuket on the small lobe.

some more surface features:

Context image showing details of Comet 67P/Churyumov–Gerasimenko’s surface features close to regional boundaries on the comet’s large lobe.


and a very close one:

Ma’at close-up



Copyright ESA/Rosetta/MPS for OSIRIS Team MPS/UPD/LAM/IAA/SSO/INTA/UPM/DASP/IDA

Close-up view of surface textures in the Ma’at region, close to the boundary with Maftet, on the small lobe of Comet 67P/Churyumov–Gerasimenko. In this boundary region the dust that dominates Ma’at seems to thin out towards Maftet, revealing rougher terrain below. In the section shown here the dust shows a pitted texture, which may suggest an ice-rich material that may be undergoing desiccation through sublimation.
The image is a crop from an image taken with the OSIRIS narrow-angle camera on 19 October 2014 from a distance of 8 km from the comet’s surface.

getting closer:

Comet on 20 July 2015 – NavCam



Released 28/07/2015 3:30 pm
Copyright ESA/Rosetta/NAVCAM – CC BY-SA IGO 3.0

This single frame Rosetta navigation camera image of Comet 67P/Churyumov-Gerasimenko was taken on 20 July 2015 from a distance of 171 km from the comet centre. The image has a resolution of 14.5 m/pixel and measures 14.9 km across.
