Edited Mars Reconnaissance Orbiter image of layers on the Martian south polar ice cap.

Edited Mars Reconnaissance Orbiter image of a cliff of ice in Malea Patera on Mars. RGB image strip (which is how MRO makes images).

Edited Mars Reconnaissance Orbiter image of blue sand dunes (but only with the proper filters) in Lyot Crater. RGB shows dark sand dunes but IRB (infrared) shows a pretty blue... IRB strip on a grayscale context image. Color/processing variant.

Edited Mars Reconnaissance Orbiter context image of where gullies are being watched.

Edited Mars Reconnaissance Orbiter image showing an area in a crater where gullies are being watched over time.

Edited Mars Reconnaissance Orbiter image of a volcanic fissure on Mars. The color images are almost monochromic making detailed processing more fun. Color/processing variant.

Edited Mars Reconnaissance Orbiter image of craters with light-colored rims. Context image.

Edited Mars Reconnaissance Orbiter image of sublimating terrain (it's made of carbon dioxide which sublimates directly to gas when the sun shines on the sun-facing edges) in the Martian south polar region.
