Summary
[edit]DescriptionAt the rim of a crater ESA23141541.png |
English: This image features the southeast wall of a small crater located a few hundred kilometres to the north of the giant Hellas impact basin on Mars. The complete crater itself is about 12 km in diameter; this image shows a 5 x 10 km area. The Colour and Stereo Surface Imaging System (CaSSIS) onboard the ExoMars Trace Gas Orbiter took the image on 19 October 2020. When viewed with CaSSIS’ colour filters, the image shows exceptional diversity in colour. This diversity is related to the presence of various minerals that reflect light differently at different wavelengths. The light-toned deposits highlight the bedrock exposures of the area, which probably contain ancient clay-rich minerals that would have formed in the presence of water. Also visible are wind-blown sandy deposits that form ripples on the floor of the crater. Their distinctive tan colour implies that they contain iron-oxide minerals. The ExoMars programme is a joint endeavour between ESA and Roscosmos. The image was featured by Science Advances online in February 2021. |
