Layered deposits in Uzboi Vallis sometimes occur in alcoves along the valley and/or below where tributaries enter it.


Holden Crater in southern Margaritifer Terra displays a series of finely layered deposits on its floor (white and light purple in an enhanced color image).


The combination of morphological and topographic information from stereo images from NASA's Mars Reconnaissance Orbiter, as well as compositional data from near-infrared spectroscopy has been proven to be a powerful tool for understanding the geology of Mars.


Depressions such as impact craters can act as traps for sediments that have been blown in from elsewhere, accumulating in various patterns whipped up by strong winds.


NASA's longest-lived mission to Mars has gained its first look at the Martian moon Phobos, pursuing a deeper understanding by examining it in infrared wavelengths.


An unexpectedly strong blast from the Sun hit Mars this month, observed by NASA missions in orbit and on the surface.
