This image captured by NASA's 2001 Mars Odyssey spacecraft shows the complexity of wind erosion on Mars. The erosion of the hills and the gouge-like pits indicate two, if not three wind directions that all altered the surface.

Craters are most often the site of gully formation on Mars. Mega-gullies are also found on the southwestern parts of Vallis Marineris, and in this image from NASA's 2001 Mars Odyssey spacecraft, on hills east of Argyre Planitia.

This image taken by NASA's Mars Reconnaissance Orbiter covers part of a candidate landing site that appears to be a shallow depression with a deposit perhaps consisting of chlorides, like table salt.

The Kasei Valles region is very complex. This image captured by NASA's Mars Odyssey illustrates that complexity with features created by fluvial action (channels) and tectonic processes (fractures).

Layers of rock in the upper portion of a tall mound near the center of Gale Crater on Mars exhibit a regular thickness of several meters in this image taken by NASA's Mars Reconnaissance Orbiter.

Sand dunes such as those seen in this image from NASA's Mars Reconnaissance Orbiter have been observed to creep slowly across the surface of Mars through the action of the wind.

Do you see what I see in this image from NASA's Mars Odyssey spacecraft? The connected craters at the top and bottom of this image look like bugs, perhaps a bumble bee at the top and a wasp at the bottom.

The channel in the bottom part of this image captured by NASA's 2001 Mars Odyssey spacecraft was created by lava flow rather than water flow. This feature is located in the Tharsis plains east of Olympus Mons.

This image from NASA's Curiosity rover just after discarding a soil sample as part of its first 'decontamination' exercise. A small amount of remnant material is visible inside the delivery tube, which is magnified in the blow-up at lower right.

Gale Crater contains a large layered deposit, part of which is shown in this image captured by NASA's 2001 Mars Odyssey spacecraft. This deposit is the target of the Curiosity Lander due to land in early August 2012.

This northeast-facing view from the lower edge of the pale 'Pahrump Hills' outcrop at the base of Mount Sharp includes wind-sculpted ripples of sand and dust in the middle ground. It was taken by Curiosity's Navcam on Nov. 13, 2014.

This image NASA's Mars Reconnaissance Orbiter shows an impact crater that was cut by lava in the Elysium Planitia region of Mars. It looks relatively flat, with a shallow floor, rough surface texture, and possible cooling cracks.
