Mars Express, of the European Space Agency (ESA), imagined part of the Martian landscape, a region at the edge of the northern and southern hemispheres, rocky and fragmented, which once formed the floodplains of the Planet red.
The region, a craggy, rocky escarpment known as Nili Fossae, lies on the border of the northern and southern hemispheres.
This is an impressive example of past activity on the planet and shows signs of wind, water and moving ice. Once moved materials from one place to another, thus carving patterns and distinctive reliefs, said in a statement Wednesday the ESA.
Despite Mars' reputation as being a dry and arid world today, water would have played a key role in the sculpture of Nili Fossae due to continued erosion.
Nili Fossae is dotted with rocky valleys, small hills and clusters of flat reliefs (called mesas in geological terms), with some pieces of crustal rock appearing to be depressed. ESA noted that, lower, creating a number of ditch-like features, called graben,
. The image also shows the terrain of Nili Fossae located at altitude. This appears to be mainly rocky plateaus, while the lower soil consists of smaller rocks, mesas, hills and others, separated by erosion channels and valleys.
It is believed that the shapes and structures scattered in this image have been shown by ESA to have shown that over time the images showed remarkably dark surface traces on the ocher background, as if they had been stained with charcoal or ink.
19659002] These are areas of darker volcanic sand that have been transported and deposited by current Martian winds. The wind often moves sand and dust over the surface of Mars, creating undulating dune fields across the planet and forming a multi-colored and fragmented terrain like Nili Fossae, the researchers said.
The data composing this image was collected by Mars Express High Resolution Stereo Camera (HRSC) on February 26th.
