Change detection and monitoring of active Martian surface phenomena with the Colour and Stereo Surface Imaging System (CaSSIS) onboard the ExoMars Trace Gas Orbiter (TGO)
Seelos, Frank P.; Tornabene, Livio L.; Osinski, Gordon R. +10 more
Mars is host to a variety of active surface processes that relate to changes in seasonal ice/frost, slope activity, wind and processes potentially relating to liquid water. Regular monitoring and change detection of these phenomena is crucial to not only provide us insights into present day Martian surface conditions, but also its past geologic an…
Assessing slope uncertainties of martian Digital Elevation Models from numerical propagation of errors on synthetic geological surfaces
Quantin-Nataf, C.; Leyrat, C.; Millot, C. +2 more
Digital Elevation Models (DEM) are widely used in planetary sciences, including for the specific case of Mars. DEMs allow us to extract topography parameters necessary in geomorphological studies. However, DEMs are not free from vertical errors, which yields uncertainties in calculations of parameters such as local slopes. In addition, slope maps …
Dendritic ridges in Antoniadi basin, Mars: Fluvial or volcanic landforms?
Mangold, N.; Thomas, N.; Hauber, E. +7 more
Antoniadi basin displays dark-toned dendritic ridges previously interpreted as inverted fluvial channels. Detailed observations of these dark-toned ridges as well as the geological units in the central region of Antoniadi basin are provided emphasizing images from the Colour and Stereo Surface Imaging System (CaSSIS), the High Resolution Stereo Ca…
