Medusa Fossae - detail 1
This image, taken by the High Resolution Stereo Camera (HRSC) on board ESA's Mars Express spacecraft, shows a detail of the Medusa Fossae formation. Here the volcanic plateau fed by the southernmost Tharsis Montes volcano Arsia Mons, is dissected by several valleys which were most likely carved by running water. Here the Senus Vallis is shown in detail as an example where the latest-stage inner channel is still visible.
The HRSC obtained this image during orbit 917 with a resolution of approximately 13 metres per pixel. It shows an area located at about 5° South and 213° East.
