Rocky islands – 3D

This image shows a part of Tithonium Chasma, on the western side of the Vallis Marineris region – also known as the ‘Grand Canyon’ of Mars. The observed area is part of the Western Tithonium Dome. Rocky outcrops are seen at different elevations – best seen when viewed through red-blue stereo ‘3D’ glasses. The structures have been interpreted as the result of erosion – perhaps by flowing water. Bluer hues indicate dust.

The image was created from a stereo pair taken by the Colour and Stereo Surface Imaging System (CaSSIS) onboard the ESA-Roscosmos ExoMars Trace Gas Orbiter on 5 February 2019.
