This image from ESA’s Mars Express shows a dried-up river valley on Mars named Nirgal Vallis. It comprises data gathered on 16 November 2018 during Mars Express Orbit 18818. The ground resolution is approximately 14 m/pixel and the images are centred at about 315°E/27°S. This image was created using data from the nadir and colour channels of the High Resolution Stereo Camera. The nadir channel is aligned perpendicular to the surface of Mars, as if looking straight down at the surface. North is to the right.
