This image from NASA's Mars Reconnaissance Orbiter spacecraft was acquired to look for frost on these generally equator-facing slopes on Mars, which are visible in the shadows after enhancing the brightness levels.
This image from NASA's Mars Reconnaissance Orbiter covers part of the chaotic terrain in Masursky Crater, and was targeted due to evidence that ejecta from Mojave Crater, to the south, may have modified the landscape.
Jezero Crater is candidate future landing site that contains sediments deposited by at least three ancient rivers as seen by NASA's Mars Reconnaissance Orbiter spacecraft. There are some good exposures of ancient bedrock.
This image captured by NASA's Mars Reconnaissance Orbiter covers the western rim of Holden Crater during northern summer. Since Holden Crater is in the Southern hemisphere of Mars, the shadows are long in northern summer (southern winter).
This image shows a set of coalesced collapse pits in western Valles Marineris as seen by NASA's Mars Reconnaissance Orbiter. Fine layers are exposed in the walls of the pits, and in some places those layers are displaced by faults.
The North Polar layered deposits provide a record of recent climate changes on Mars as seen by NASA's Mars Reconnaissance Orbiter spacecraft. Color variations between layers are due to differences in composition of the dust.
This image was targeted for NASA's Mars Reconnaissance Orbiter spacecraft to look at a candidate new crater on a lobate apron. Such aprons are often ice-rich, but the crater shows no bright material that would indicate ice.
Alluvial fans are gently-sloping wedges of sediments deposited by flowing water. Some of the best-preserved alluvial fans on Mars are in Saheki Crater, seen here by NASA's Mars Reconnaissance Orbiter spacecraft.
New Waypoint, Science Team Newcomers for Curiosity
This map shows the route driven by NASA's Curiosity Mars rover from the location where it landed in August 2012 to its location in early March 2016, approaching a geological waypoint called Naukluft Plateau.
This image captured by NASA's Mars Reconnaissance Orbiter spacecraft was taken to look at seasonal frost in gullies during southern winter on Mars, with the Sun only about two degrees over the horizon (just before sunset).
West of NASA's Curiosity landing site, this image from NASA's Mars Reconnaissance Orbiter spacecraft along the northwestern floor of Gale Crater is between Aeolis Mons (informally called 'Mt. Sharp') and the crater rim.
NASA's Mars Reconnaissance Orbiter used its HiRISE camera to obtain this view of an area with unusual texture on the southern floor of Gale Crater. An enigmatic deposit appears to have flowed into the small crater from the south.
