A grid of small polygons on the Martian rock surface near the right edge of this view may have originated as cracks in drying mud more than 3 billion years ago. Multiple images of this view were combined for this view from NASA's Curiosity Mars rover.

Possible Signs of Ancient Drying in Martian Rock

The network of cracks in this Martian rock slab called 'Old Soaker' may have formed from the drying of a mud layer more than 3 billion years ago. The view combines three images taken by NASA's Curiosity Mars rover on Dec. 31, 2016.

Bedrock on a Crater Floor

Shown in this image from NASA's Mars Reconnaissance Orbiter are fan-shaped deposits emerging from regions of steep topography called alluvial fans. Alluvial fans on Mars are thought to be ancient and record past episodes of flowing water.

The Case of the Martian Boulder Piles

NASA's Mars Reconnaissance Orbiter shows Mars' northern-most sand dunes beginning to emerge from their winter cover of seasonal carbon dioxide (dry) ice. Dark, bare south-facing slopes are soaking up the warmth of the sun.

Relics of Rover's Landing

These two views from NASA's Curiosity rover, acquired specifically to measure the amount of dust inside Gale Crater, show that dust has increased over three days from a major Martian dust storm.
