Summary

[edit]
Description
English: A jagged slice in a crater wall on Mars stands out brightly against the darker terrain in this image taken by the CaSSIS camera on the ESA-Roscosmos ExoMars Trace Gas Orbiter at 7pm local time on 1 May 2021.
Despite the low light in this late evening image, several north-facing icy scarps are distinctly visible because of their covering of bright white carbon dioxide frost. The frost disappears in spring, but remains late on these scarps because of their pole-facing orientation.
This 11 km diameter crater is located in the northern plains of Mars at 55°16'51.6"N/106°25'3.4"W, north of Alba Mons.
Français : Sur cette image prise par la caméra CaSSIS de la sonde ExoMars Trace Gas Orbiter (ESA-Roscosmos), à 19 heures, heure locale, le 1er mai 2021, la paroi d'un cratère martien se détache nettement du terrain plus sombre.

Malgré la faible luminosité de cette image de fin de soirée, plusieurs cicatrices glacées orientées vers le nord sont nettement visibles en raison de leur couverture de givre blanc brillant de dioxyde de carbone. Le givre disparaît au printemps, mais reste tardivement sur ces cicatrices en raison de leur orientation vers le pôle.

Ce cratère de 11 km de diamètre est situé dans les plaines nord de Mars à 55°16'51.6 "N/106°25'3.4 "W, au nord d'Alba Mons.
