A vegetable grater on Mars

A vegetable grater on Mars

Cool image time! I honestly can’t think of any better term but “vegetable grater” to describe the strange surface in the image on the right, cropped from the full sized image that was released with the July 11, 2018 monthly release of new images from the high resolution camera on Mars Reconnaissance Orbiter (MRO).

If you click on the image you can see the whole image, which merely shows more of the same terrain over a wider area. When I cropped it, I literally picked a random 450×450 pixel-sized area, since other than slight variations the entire terrain in the full image is as equally rough. The resolution captures objects as big as five feet across.

Looking at the full image there does seem to be flow patterns moving across the middle of the image, but if so these flow patterns had no effect on the surface roughness, other than indicating a very slight difference in the size of the knobs and pits. Overall, very strange.

The location of this place on Mars is in the cratered southern highlands, to the southwest of Hellas Basin, as indicated by the black cross in the image below.
