This computer-generated perspective view was created using data obtained from the High-Resolution Stereo Camera (HRSC) on ESA’s Mars Express. Centred at around 18°S and 329°E, this image has a ground resolution of about 20 m per pixel. Above the interconnected craters of Sigli and Shambe (west), flow channels can be seen leading in to the large impact basin. The outflow of Ladon Valles itself can be seen towards the bottom of the image (east). Scientists have detected clay minerals within these deposits, suggesting the relatively long-lasting presence of liquid water in the past.
