They show the Deuteronilus Mensae region, located on the northern edge of Arabia Terra and bordering the southern highlands and the northern lowlands. Situated at approximately 39° North and 23° East, Deuteronilus Mensae are primarily characterised by glacial features. The scene is illuminated by the Sun from the south-west (from bottom left in the image).
This image shows the Deuteronilus Mensae region on Mars, an area primarily characterized by glacial features. It was taken on 14 March 2005 (orbit number 1483) by the High Resolution Stereo Camera (HRSC) onboard ESA’s Mars Express with a ground resolution of approximately 29 metres per pixel. The area is located on the northern edge of Arabia Terra and borders the southern high- and northern lowlands, at approximately 39° North and 23° East. The scene has been derived from the three HRSC colour channels and the nadir channel. Credits: ESA/DLR/FU Berlin (G. Neukum)
The scene is dominated by a depression measuring approximately 2 000 metres in depth and 110 kilometres in diameter, north to south.
Visible in the centre of the first image, the interior of the depression is characterised by dark material, differing from the light-toned surrounding plains.
Deeply incised valleys of a depth ranging from 800 to 1 200 metres are clearly identifiable in the northern part of the scene. Deeply incised valleys with a depth ranging from 800 to 1 200 metres are clearly identifiable in the northern part of the scene.
It is believed that these valleys may have originated due to intense flooding by melted water ice. The water then froze rather quickly, flowing down the slopes of the depression like a glacier. Aeolian sediments (eroded by the action of wind) traced the flow pattern on the surface.
The northern part exhibits a finger - shaped elevation which was circumvented by the masses of water and ice.
To the west, the flow of water mixed with ice broke through another elevation and formed a drop - shaped feature while flowing into the depression.
Mars experienced numerous events of this kind in the past, when rising magma or impacts caused frozen groundwater to melt resulting in major flooding events.
One of the most striking features on Mars is the dichotomy between the southern highlands and the northern plains, lower by up to 3 kilometres. The boundary between these two regions is marked by a transition characterised by an intact highland zone and areas with remnant mesas and isolated eroded knobs.
The scene of Deuteronilus Mensae depicts different stages of highland degradation. Numerous flow patterns in wide valleys and along ridges and scarps indicate movement of debris mixed with ice towards the surrounding areas.
Since the discovery of these structures, scientists assume that the mixture of debris and ice resembles rock glaciers commonly found in cold-climate areas on the Earth.
As on Earth, these landscapes are climate indicators. Whether ice could be still present in the porous spaces in Martian features and how active these landforms may be today is still a subject of discussion.
The colour scenes have been derived from the three HRSC colour channels and the nadir channel. The perspective views have been calculated from the digital terrain model derived from the stereo channels. The anaglyph image was calculated from the nadir and one stereo channel. The black and white high - resolution images were derived from the nadir channel which provides the highest detail of all channels. Image resolution has been decreased for easier downloading.

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
