The Medusae Fossae formation
This image from ESA’s Mars Express shows part of what is possibly the largest single source of dust on Mars: a wind-sculpted feature known as the Medusae Fossae Formation (MFF). The MFF is remarkably extensive – it is the largest sedimentary deposit on the planet and stretches out discontinuously for more than 5000 km, covering an area about the size of India.
This image comprises data gathered by ESA’s Mars Express using its High Resolution Stereo Camera (HRSC) on 14 May 2021. The colour image was created using data from the nadir channel, the field of view aligned perpendicular to the surface of Mars, and the colour channels of the HRSC. The ground resolution is approximately 19 m/pixel and the images are centred at about 192°E/2°N. North is to the right.
