Rim of Crater Huygens on Mars

These images, taken by the High Resolution Stereo Camera (HRSC) on board ESA’s Mars Express spacecraft, show the eastern rim of the Martian impact crater Huygens.

The images were taken during orbit 532 in June 2004 with a ground resolution of approximately 70 metres per pixel. The displayed region is centred around longitude 61° East and latitude 14° South.

Huygens is an impact structure, about 450 kilometres wide, located in the heavily cratered southern highlands of Mars. Crater counts of the rim unit of the impact basin indicate that it is almost 4000 million years old.


This implies that this basin was formed in the early history of the planet and indicates a period of heavy bombardment in roughly the first 500 million years of the planet’s lifetime.

The basin shows an inner ring that has been subsequently filled by sediments transported into the crater. These images show part of the eastern rim of the crater. The rim is heavily eroded and shows a ‘dendritic’ pattern. This observation suggests surface water run-off.

Dendritic systems are the most common form of drainage system found on Earth. They consist of a main ‘river’ valley with tributaries with their own tributaries. From above, they look like a tree or a river delta in reverse.

The valley system is blanketed by dark material, which was either transported by a fluid running through the channels or by wind-driven (‘aeolian’) processes. Part of the area has been covered by slightly redder material, which implies a different chemical composition.

Image resolution has been decreased for use on the internet. The colour images were processed using the nadir (vertical view) and 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: Scientists channel graphene to understand filtration and ion transport into cells

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.

To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...

Im Focus: Towards data storage at the single molecule level

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.

Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
