The European Space Agency (ESA) has photographed part of the Martian landscape, a region located at boundary of the northern and southern hemisphere which is rocky and fragmented, which once formed the flood plains of the red planet.
The data constituting this image was collected by Mars Express's High Resolution Stereoscopic Camera (HRSC) on February 26th.
Nili Fossae on Mars
The region, a craggy and rocky escarpment known as Nili Fossae lies at the edge of the northern and southern hemisphere.
This is an impressive example of past activities on the planet and shows the places where wind, water and ice transported materials from one place to another, creating distinct patterns and reliefs. said the ESA in a statement last week, according to IANS.
Despite Mars' reputation as a dry and arid world these days, it is thought that water played a key role in Nili Fossae's sculpture via erosion in progress.
Nili Fossae is filled with rocky valleys, small hills, and groups of flat reliefs (called mesas in geological terms), with some pieces of crustal rocks appear to be sunk into the surface, creating a number of ditch-like features. like graben, noted ESA.
Land of altitude of Nili Fossae
In addition, the image also showed the terrain of Nili Fossae, located at a higher altitude.
It seems to be mostly rocky plateaus, while the low ground includes small rocks, mesas, hills and more, with the two sections roughly separated by erosion channels and valleys.

The shapes and structures scattered throughout this image would have been shaped over time by flows of not only water and ice, but also wind, said the ESA.
Martian winds
The images show spots on the surface that appear to be especially dark on the ocher background, as stained with charcoal or ink.

These are areas of darker volcanic sand, which have been transported and deposited by the current Martian winds.
The wind often moves sand and dust over the surface of Mars, creating undulating dune fields The researchers explained that the land crossed the planet and formed a varied and multicolored terrain like Nili Fossae.
