Okay, I got the point. Perhaps I would have liked a more science-driven release. For example, I would have liked to learn about the science target of this image (I know many HiRISE images have one)

Cheers

Sorry for this note, but boulders that moved downhill with tracks have been seen since the first very high resolution images of the moon. So I personally don't get why this image (surely a great HiRISE image, don't get me wrong) should get more attention than others.

To this I would add that "landslide"/mass movement tends to move material to a lower gravitationally potential. The identification of mass wasting features is intuitive on large spherical bodies, e.g., on Mars a topographically lower material has a gravitationally lower potential. On this comet, however, one first needs to have an idea of the gravity field. A local topographic low does not necessarily have a lower gravitational potential.

So I would say that mass wasting identification can be tricky on this comet.
Striations might have a primordial origin or be formed by shock during impact on a former parent body. A plane analysis of the striations and a plot of the planes's pole would help to elucidate this.

Cheers

Normal to the possible "layering", there seems to be some "ridges". How did they formed...perhaps mass wasting in low-gravity environment?

Or are these erosion-resistant conduits seen in section?

I guess the smooth and brigther areas on the comet are good candidate for landforms formed by deposit of non-icy material

That's tentalizing! Similar features were seen on Wild 2 and interpreted as possible erosion-resistant fumaroles. Check out Figure 6 in this article. With the resolution of OSIRIS I would expect to see summit pit on these pinnacles.

Also, 67P seems to have a lot of structural features, such as parallel linear ridges and scarps that, if I remember correctly, were rarely seen on previous comets. These structures characterize both the head and the body and might be primary structures, supporting the idea that head and body are genetically related, i.e., they formed on an originally single object.
