Crater Hale in Argyre basin

Crater Hale in Argyre basin


Crater Hale in perspective, looking west


These images, taken by the High Resolution Stereo Camera (HRSC) on board ESA’s Mars Express spacecraft, show Crater Hale in the Argyre basin of the southern hemisphere of Mars.

The images show an area close to the northern rim of the Argyre basin, located at latitude 36° South and longitude 324° East. The image was taken with a ground resolution of about 40 metres per pixel during Mars Express orbit 533 in June 2004.

Slight periodic colour and brightness variations in parts of the image indicate atmospheric waves in clouds.



Crater Hale, with its terraced walls, central peak and a part of the inner ring is visible in the upper (eastern) part of the image. The region has been eroded heavily by deposits caused by this impact, and subsequent processes.
On the southern rim of Hale, parts of the crater wall have moved downslope towards the crater’s centre (see black and white detailed image left).

At the bottom (western) part of the picture, as seen below in the other detailed image with high resolution, the surface shows a network of fluvial channels which may have been caused by running water.

The HRSC experiment on ESA’s Mars Express mission is led by the Principal Investigator Prof. Dr Gerhard Neukum, of the Freie Universitaet Berlin, who also designed the camera. The science team for the experiment consists of 45 Co-Investigators from 32 institutions and 10 nations.

The camera was developed at the German Aerospace Center (DLR) and built in co-operation with industrial partners EADS Astrium, Lewicki Microelectronic GmbH and Jena-Optronik GmbH.

The HRSC is operated by the DLR Institute of Planetary Research, through ESA’s European Space Operations Centre in Darmstadt, Germany.

Image resolution has been decreased for use on the internet. The colour images were processed using the HRSC nadir (vertical view) and three colour channels. The perspective views were calculated from the digital terrain model derived from the stereo channels. The 3D anaglyph image was created from the nadir channel and one of the stereo channels. Stereoscopic glasses are needed to view the 3D image.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
