Panda stripe dustslides

A piece of Mars: This 600x450 m (1969x1476 ft) scene of a hillside shows new, dark dustslides that slid downhill (to the lower left). Faint stripes of older dustslides are visible, covered by bright dust and small ripples. Thousands of ...

Textured gullies

A piece of Mars. These are gullies on a martian hillside (upslope is to the upper right). Water may be what forms the channels, carrying soil and rocks downslope. The textured pattern of the lower slope is caused by the ...

Rivers of freezing gas

A piece of Mars: This 600x450 m (1969x1476 ft) polar scene shows sinuous channels 2-8 m (7-26 ft) wide carved out of ice-filled and ice-covered terrain. They're not formed by flowing water, but instead by flowing gas that gets trapped ...

Huge wind-made cliffs

A piece of Mars: Topography in color is draped over an image of a windblown cliff. The entire shape of the landscape here was formed by wind, from the large 400 m (1312 ft) tall zigzag cliff, to the small ...

Mars is watching you…

A piece of Mars: This looks like a pair of eyes looking at us. It's really some small brown hills, two of which (the "eyes") are surrounded by dark gray sand that has blown into scours as the wind interacts ...

Almost a dune

A Piece of Mars: This field of 2 m wide sand ripples has a dark splotch in the middle (the scene is 300x225 m or 984x738 ft). The splotch is the peak of a low hill that straddles the ...

Lumpy bumpy dunes

A piece of Mars: These funny shaped dunes were formed by winds blowing from two directions - one from the top of the frame and one from the upper right. Both winds make steep slopes (slip faces) on the downwind ...

Changing winds

A piece of Mars: There are two sets of ripples here: tan ones and gray ones, each oriented to a different wind (scene is 300x225 m, or 984x738 ft). The gray ones sit on top of the tan ones, so ...

Missing bedrock

A piece of Mars: Wind flow on Mars can be quite dramatic. Here, a single wind-sculpted hill stands 1.5 km (0.93 mi) wide and 600 m (1970 ft) high (color shows elevation). That sounds big, but vastly larger is the ...

Holes around rocks

A piece of Mars: This scene (509x382 m, or 1670x1253 ft), aside from showing some lovely rippled dunes, has many car-sized boulders in it. Some are surrounded by ditches in the sand, like little moats. Why? The sand is blown ...
