Here is an image from Rosetta of comet 67P/G-C on 22 August. Rosetta has been in “pyramid” shaped orbits to observe and approach the comet to get the date needed to get even closer in time. Check out the Rosetta blog for a nice description.
The close points of the trianglular or pyramid orbit has gone from 79 km to orbits in the 50 km range. the image above from 54 km. In just a couple of weeks the orbits will be close the 30 km.
I particularly like this image. Aside from the already good and improving detail, it is a nice look down into the central area below the cliffs. What is that material at the base of the cliff? Why is it there? Did it come from the “cliffs” like a landslide?
