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: The pyrenoid is a carbon-fixing liquid droplet

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Im Focus: Highly precise wiring in the Cerebral Cortex

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.

The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...

Im Focus: Quantum Sensors Decipher Magnetic Ordering in a New Semiconducting Material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.

Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
