Six hundred recent observations of the Mars landscape from an orbiting telescopic camera include scenes of sinuous gullies, geometrical ridges and steep cliffs.
Each of the 600 newly released observations from the High Resolution Imaging Science Experiment (HiRISE) camera aboard NASA’s Mars Reconnaissance Orbiter covers an area of several square miles on Mars and reveals details as small as desks.
The camera is one of six instruments on NASA’s Mars Reconnaissance Orbiter, which reached Mars in 2006. For more information about the mission, see http://mars.jpl.nasa.gov/mro/.
Ancient Lava Plain in Thaumasia Planum (PSP_002432_1525)

This observation samples part of an ancient lava plain in Thaumasia Planum. The stack of lava flows has been folded into dunes the size of a chain of hills, as is visible in the center of the image.
The lava and the dunes has been degraded by erosion. The numerous craters and dunes attest to two of the erosional processes—meteorite impacts and the wind.
