Back Right CIVA Image - Annotated

This is an annotated version of the previous image. I have outlined the cryorocks. The green cryorock is a continuation of the blue cryorock seen in the Back CIVA image. The points on it actually cast a shadow and I have outlined these with a dotted green line. The blue cryorock is a continuation of the bright cryorock at the front right of Philae's alcove. The bright area is highly contoured, with pits and depressions creating a very uneven surface. Areas where the exfoliated surface still retains the outline of the cryorocks, the surface seems relatively even. I have tried to show some of the contours of this cryorock using the dotted blue line. The right end is actually off the ground and the bulge at the bottom front is hidden behind the green cryorock. Top right of the image can be seen the ROMAP probe sticking out of the back right corner of Philae, which also casts a shadow. I am guessing these shadows are from the small amount of light being reflected off the left wall of the alcove. Bottom centre is the rest of Philae's back foot, seen also in the corner of the backward facing image. It is partially covered in gravel and is actually buried quite deep, up to the top of the end of the landing leg. Its straight outline is conspicuously alien to the rest of the image. The indentation the foot has made has also been shown. Again we see that what looks like the outline of a solid object is in fact an extremely soft compressible material. Knowing the height of Philae's foot a good estimate of the depth of the aerogel like surface layer can be made. Credits: ESA/Rosetta/NAVCAM – CC BY-SA IGO 3.0
