Annotated: Nectaris Fossae and Protva Valles

This image from ESA’s Mars Express shows Nectaris Fossae and Protva Valles, complex geological features found on Mars. Key features are labelled across the frame: the broad, deep incised, and intensely eroded valleys of Protva Valles; three prominent wrinkle ridges; and the dust-filled fractures of Nectaris Fossae.

This image comprises data gathered by Mars Express’ High Resolution Stereo Camera (HRSC) on 23 May 2022. It 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. It is a ‘true colour’ image, reflecting what would be seen by the human eye if looking at this region of Mars.

North is to the right. The ground resolution is approximately 23 m/pixel and the image is centred at about 27°S/301°E.
