These two frames were taken of the same place on Mars by the same orbiting camera onboard NASA's Mars Reconnaissance Orbiter before (left) and after some images from the camera began showing unexpected blur.

An enhanced-color image from NASA's Mars Reconnaissance Orbiter (MRO) reveals bedrock that is several kilometers below the top of the giant Valles Marineris canyons.

Intricate gullies have formed on the northern wall of this impact crater located in the Terra Cimmeria region in this image from NASA's Mars Reconnaissance Orbiter (MRO).

This image from NASA's Mars Reconnaissance Orbiter (MRO) shows streaks forming on slopes when dust cascades downhill. The dark streak is an area of less dust compared to the brighter and reddish surroundings.

This image from NASA's Mars Reconnaissance Orbiter (MRO) shows an impact crater looking amusingly like a tadpole because of the valley that was carved by water that used to fill it.

This graph shows rising air during a 2007 global dust storm on Mars lofted water vapor into the planet's middle atmosphere based on data from the Mars Climate Sounder instrument onboard NASA's Mars Reconnaissance Orbiter.

This image from NASA's Mars Reconnaissance Orbiter shows hexagons in icy terrain. Polygonal patterns form by winter cooling and contraction cracking of the frozen ground.

This image from NASA's Mars Reconnaissance Orbiter shows blocks of layered terrain within the Olympus Mons aureole. The aureole is a giant apron of chaotic material around the volcano.

Layers, probably sedimentary in origin, have undergone extensive erosion in this image from NASA's Mars Reconnaissance Orbiter (MRO) of Shalbatana Valles, a prominent channel that cuts through Xanthe Terra.

Ladon Basin was a large impact structure that was filled in by the deposits from Ladon Valles, a major ancient river on Mars as seen in this image from NASA's Mars Reconnaissance Orbiter (MRO).

Two 2001 images from NASA's Mars Global Surveyor orbiter show a dramatic change in the planet's appearance during a dust storm.

A cross-section of a thick sheet of underground ice is exposed at the steep slope (or scarp) that appears bright blue in this enhanced-color view from NASA's Mars Reconnaissance Orbiter.

At this wedge-shaped pit on Mars, the steep slope (or scarp) at the northern edge exposes a cross-section of a thick sheet of underground water ice in this image from NASA's Mars Reconnaissance Orbiter.

This inner slope of a Martian crater has several of the seasonal dark streaks called "recurrent slope lineae," or RSL, that a November 2017 report interprets as granular flows, rather than darkening due to flowing water. The image is from the HiRISE camera on NASA's Mars Reconnaissance Orbiter.

This diagram illustrates an interpretation for the origin of some deposits in the Eridania basin of southern Mars as resulting from seafloor hydrothermal activity more than 3 billion years ago.
