Wide field camera: fourth frame

The camera has now panned further up and seems to be pointing downwards at about 45 degrees.

Again this is clearly a weathered scene where water is or has been present, although it currently looks arid.  Most details are as in the previous frame.  Two faults are visible running diagonally across the image.  These are perhaps caused by the material drying over time, or by separate episodes of deposition of material – perhaps there is seasonal deposition.

Most intriguing is the close examination of the loose granular material on the surface.  Most, but not all, of this seems to be mineral.  However it appears that some of it is not: if this picture had been made on Earth then the immediate conclusion would be that this material was the remains of vegetation.

It is not, yet, safe to draw such a conclusion on the basis of these images, but if it is correct, then this image is the first evidence for something astonishing: this is evidence of life on another planet, orbiting a different stellar system.
