ESA Mars Express Mission sends marvelous images of Mars' heart


The European Space Agency (ESA) has recorded part of the Martian landscape, a region at of the Northern and Southern hemispheres which is rocky and fragmented, which once formed the floodplains of the red planet.

Data containing this image was collected by Mars Express "High Resolution Stereo Camera (HRSC) on February 26th.

Nili Fossae on Mars

The region, a full – scale escarpment, known as the Nili Fossae is at the limit of the northern and southern hemisphere.

It is an impressive example of previous activity on the planet and shows signs of wind, water and ice moving with moving materials from one place to another, sculpting distinct patterns and reliefs as it did, said ESA in a statement last week, according to IANS.

Despite the reputation of Mars as a dry and arid world today, it is believed that water played a key role in the sculpture of Nili Fossae continuous erosion.

Nili Fossae is full of rocky valleys, small hills, and groups of full-grown reliefs (known as geological mesa), with some pieces of crust rock that appear to be depressed on the surface, creating a series of similar features of grave ditches, ESA noted.

Terrain of higher altitude than Nili Fossae

In addition, the image also showed the higher pitch of Nili Fossae.

This seems to be made up of rocky plateaus, while the inferior field comprises smaller rocks, mesas, hills and furthermore, the two sections being very much separated from the erosion and valley channels.

The shapes and structures scattered in this image are believed to have been shaped over time by not only water and ice flows, but also wind, said ESA.

Images showed surface traces that seem to be especially the dark on the background of the ocher, as if it were dirty with charcoal or ink.

These are darker volcanic sand areas that have been transported and stored by the current Martian winds.

The wind frequently drives sand and dust from the surface of the planet, creating fields of thriving dunes along the planet and forming a colorless, uneven ground like Nili Fossae, the researchers said.
