Edited Mars Reconnaissance Orbiter image of sand dunes on the base of Huggins Crater with lines from dust devils crossing the dune field. Color/processing variant.

Edited Mars Reconnaissance Orbiter image of Iani Chaos.

Edited Mars Reconnaissance Orbiter</b image of sand dunes named Tleilax. (I don't know where the name comes from but it sounds like some kind of laxative...)

Edited Mars Reconnaissance Orbiter image of a partly-cloudy day over Hypanis Vallis.

Edited Mars Reconnaissance Orbiter PR image of a montage of the landing site of the InSight lander. The left side shows the site in June of 2020 and the right side shows the site soon after InSight landed in November of 2018. NASA's point of the montage was to show the dark stain from the landing is fading away.

Edited Mars Reconnaissance Orbiter image of a chaotic region on Mars.

Edited Mars Reconnaissance Orbiter image of streaks of dark material in Malea Planum in Mars' south polar region.

Edited Mars Reconnaissance Orbiter image of an ice-filled crater. Crop showing the icy crater and processed even more - you can see what looks like a trail of distrubed terrain headed towards the lower-right of the image.

Edited Mars Reconnaissance Orbiter Image of possible light-toned clays on the basin floor of Ladon Valles. Color variant.

Edited Mars Reconnaissance Orbiter image of teardrop defrosting features (presumably shapes) on sand dunes. Martian sand dunes tend to defrost in the oddest shapes... Color variant.

Edited Mars Reconnaissance Orbiter image of broken up terrain in southern Aram Chaos. Color/processing variant.

Edited Mars Reconnaissance Orbiter image of hills in the northern plains of Mars.

Edited Mars Reconnaissance Orbiter image of possible jarosite-rich strata in Ius Chasma on Mars. (Jarosite is a sulfate mineral formed by the oxidation of iron (I had to look that up).)

Edited Mars Reconnaissance Orbiter image of the east end of a valley that cuts through the crater wall Jezero Crater.
