HiRISE captured this image (in 2007) of an eroded mesa made famous by its similarity to a human face in a Viking Orbiter image with much lower spatial resolution and a different lighting geometry.

Compared to the original Viking image, HiRISE shows incredible detail, even from 300 kilometers above the surface.
