While this may look like a still from “2001: A Space Odyssey,” it’s actually the slope of a crater in the north polar region of Mars. This crater has lobate features that one researcher suggested could be produced by what is called “solifluction,” which is the gradual movement of wet soil or other material down a slope (melting and creep.)

The suggester for this image hypothesizes that carbon dioxide frost processes could have similar effects, so taking several images might help to see how the frost and the lobate features relate to one another. (Lobate is something resembling a lobe.)
