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.
Several channels are located on the flank of Hecates Tholus. In this image captured by NASA's 2001 Mars Odyssey spacecraft, one of those channels enters a crater, creating a deposit on the floor of the crater.
This image from NASA's 2001 Mars Odyssey spacecraft, located southwest of Olympus Mons, contains a very subtle windstreak in the bottom 1/3 of the image. Originating at a small crater, the windstreak records a wind that blew east to west.
This stereo view combining images taken on Feb. 10, 2014, by the Navigation Camera (Navcam) on NASA's Curiosity Mars rover looks back to where the rover crossed a dune at 'Dingo Gap' four days earlier. You need 3D glasses to view this image.
This panorama combining images taken on Feb. 10, 2014, by NASA's Curiosity Mars rover looks back to where the rover crossed a dune at 'Dingo Gap' four days earlier. The view is centered toward the east and spans about 225 degrees.
Curiosity's View Back After Passing 'Junda' Striations
On Feb. 19, 2014, NASA's Curiosity Mars rover looked back after finishing a long drive. The rows of rocks just to the right of the fresh wheel tracks in this view are an outcrop called 'Junda.' This view is looking toward the east-northeast.
This dramatic image observed by NASA's Mars Reconnaissance Orbiter shows dark rippled bodies of sand, sometimes in the form of dunes, streaming through Ganges Chasma. The floor of the canyon is covered by hills and mesas.
Towards the top of this image from NASA's 2001 Mars Odyssey spacecraft is a 'T' shaped depression and two sections of narrow channel located on the northeast part of the Elysium Mons volcanic complex. Fluids (like water, or lava) flow downhill.
Map of Recent and Planned Driving by Curiosity as of Feb. 18, 2014
This map shows the route driven and route planned for NASA's Curiosity Mars rover from before reaching 'Dingo Gap' in upper right, to the mission's next science waypoint, 'Kimberley' (formerly referred to as 'KMS-9'), lower left.
Curiosity Mars Rover's Shadow After Long Backward Drive
NASA's Curiosity Mars rover caught its own shadow in this image taken just after completing a drive of 329 feet (100.3 meters) on the 547th Martian day, or sol, of the rover's work on Mars (Feb. 18, 2014).
Opportunity Rover on 'Murray Ridge' Seen From Orbit
NASA's Mars Reconnaissance Orbiter caught this view of NASA's Mars Exploration Rover Opportunity on Feb. 14, 2014. The red arrow points to Opportunity at the center of the image. Blue arrows point to tracks left by the rover in October 2013.
This image captured by NASA's 2001 Mars Odyssey spacecraft shows a portion of the huge dune field located at the north polar cap. As spring continues to deepen, the dunes are becoming darker and darker as they lose their winter frost cover.
