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.
A Possible Landing Site in Aram Dorsum for the ExoMars Rover
This image captured by NASA's Mars Reconnaissance Orbiter is of an area called Aram Dorsum (also known by its old name, Oxia Palus) that has been suggested for the 2018/2020 ExoMars Rover because it contains an ancient, exhumed alluvial system.
Hellas Crater in the ancient highlands contains some of the clearest evidence on Mars for glacial processes. This image from NASA's Mars Reconnaissance Orbiter shows a number of features consistent with glaciation.
The main map shows landforms near NASA's Curiosity Mars rover as the rover's second anniversary of landing on Mars nears. The gold traverse line ends at Curiosity's position as of July 31, 2014 (Sol 705).
Layers and Sand on the Floor of Schiaparelli Crater
Schiaparelli Crater is a 460 kilometer (286 mile) wide multi-ring structure. However, it is a very shallow crater, apparently filled by younger materials such as lava and/or fluvial and aeolian sediments as seen by NASA's Mars Reconnaissance Orbiter.
This image from NASA's Mars Reconnaissance Orbiter shows what is termed a pedestal crater, so-called because the level of the surface adjacent to the crater is elevated relative to the surface of the surrounding terrain.
Many of the depressions in Noctis Labyrinthus contain water-bearing minerals, suggesting that water was available and persistent in this region during the Late Hesperian to Amazonian epochs on Mars, as seen by NASA's Mars Reconnaissance Orbiter.
