Perennial Frost in a Crater on the Northern Plains
Most surface ice on Mars is temporary. The polar layered deposits are thick stacks of permanent water ice at each pole, and the South Polar residual cap may be a permanent (although dynamic) layer of carbon dioxide ice as seen by NASA's Mars Reconnaissanc
A Collection of Landforms in Eastern Elysium Planitia
In the northern section of this from image NASA's Mars Reconnaissance Orbiter, we see flat terrain that is probably an ancient lava field. These dust avalanches are common in dust-covered regions on Mars.
The objective of this observation from NASA's Mars Reconnaissance Orbiter is to examine a light-toned deposit in a region of what is called 'chaotic terrain' at the base of the Valles Marineris canyon system.
This observation from NASA's Mars Reconnaissance Orbiter shows both dome and barchan dunes in a small sand dune field on the floor of Newton Crater, an approximately 300 kilometer (130 mile) wide crater in the Southern hemisphere of Mars.
Continual Dune and Ripple Migration in Nili Patera
Nili Patera is a region on Mars in which dunes and ripples are moving rapidly. HiRISE continues to monitor this area every couple of months to see changes over seasonal and annual time scales as seen by NASA's Mars Reconnaissance Orbiter.
Curiosity Mars Rover's Route from Landing to 'Pahrump Hills'
This map shows the route driven by NASA's Curiosity Mars rover from the 'Bradbury Landing' location where it landed in August 2012 to the 'Pahrump Hills' outcrop where it drilled into the lowest part of Mount Sharp.
This image, taken by NASA's Mars Reconnaissance Orbiter, shows the transition between the 'Murray Formation,' in which layers are poorly expressed and difficult to trace from orbit, and the hematite ridge, which is made up of continuous layers.
This image, taken NASA's Mars Reconnaissance Orbiter, shows distinct bands of alternating tone and brightness within the 'Murray Formation' on Mars. Outcrops like this are common throughout the formation.
This is a map of lower Mount Sharp on Mars, showing the major geologic units identified from orbit. The rocks of the 'Murray Formation,' mapped in green, likely represent the oldest layers of Mount Sharp that NASA's Curiosity rover will explore.
The route of NASA's Mars Curiosity rover up the slopes of Mount Sharp on Mars is indicated in yellow in this image. The rover's current position is marked with a star. This new route provides excellent access to many features in the 'Murray Formation.'
This topography map shows a portion of the Gale Crater region on Mars, where NASA's Mars Curiosity rover landed on August 6, 2014. The rover (marked with a star) is currently headed toward 'Pahrump Hills.'
Lava flows south of Arsia Mons in Daedalia Planum transition from younger flows with elongated, sinuous morphologies to the northeast, to older, broader lobes and sheet flows to the southwest. This image is from NASA's Mars Reconnaissance Orbiter.
The tropics of Mars are commonly littered with small bright ripples that were somehow shaped by the wind. NASA's Mars Reconnaissance Orbiter might provide a valuable clue to the formation of transverse aeolian ridges (TARs) elsewhere on Mars.
Eridania is the name of topographically enclosed basin located in the Southern highlands of Mars that has been suggested to be the site of a large ancient lake or inland sea. This image is from NASA's Mars Reconnaissance Orbiter.
This mantle observed by NASA's Mars Reconnaissance Orbiter is thought to be deposited as snow during periods when the angle of the tilt of Mars' rotational axis-called obliquity-is much higher, which last happened around 10 million years ago.
