Mars' north polar deposits comprise a thick stack of icy layers. Part of this image from NASA's Mars Reconnaissance Orbiter (MRO) has lingering seasonal frost, which serves to accentuate those layers.

NASA's Mars Reconnaissance Orbiter observed this image of an impact crater. The blue appearance is due to the intense blast of the impact moving around dust on the surface. That dust is usually light-toned and reddish in color compared to what is ...

This set of images from NASA's Mars Reconnaissance Orbiter shows a fierce dust storm is kicking up on Mars, with rovers on the surface indicated as icons.
This graphic shows the ongoing contributions of NASA’s rovers and orbiters during a Martian dust storm that began on May 30, 2018.

This image from NASA's Mars Reconnaissance Orbiter shows an impact crater that triggered a slope streak. When a meteoroid hit the surface and exploded to make the crater, it destabilized the slope and initiated this avalanche.

This image from NASA's Mars Reconnaissance Orbiter shows a hill with a central crater. Such features have been interpreted as both mud volcanoes (really a sedimentary structure) and as actual volcanoes (the erupting lava kind).

NASA's Mars Reconnaissance Orbiter (MRO) keeps finding new impact sites on Mars. This one occurred within the dense secondary crater field of Corinto Crater. The new crater and its ejecta have distinctive color patterns.
May 29, 2018
In early Martian summer, at the time NASA's Mars Reconnaissance Orbiter (MRO) acquired this image, the dunes are almost free of their seasonal ice cover.
