Landslides are common features found on steep slopes on Mars and the role of water in their formation is an open question. Our study focuses on three young martian landslides whose mechanism of formation is unknown and knowing their formation mechanism could give us key information on recent martian climate and/or tectonics. They are less than 5 k…

Topographic correction of HiRISE and CaSSIS images: Validation and application to color observations of Martian albedo features
DOI: 10.1016/j.pss.2021.105198 Bibcode: 2021P&SS..20005198M

The topographic correction of satellite images has to be applied to both disentangle albedo features from illumination effects induced by local topography and perform spectrophotometric analyses of planetary surfaces. This work focuses on the modeling and removal of surface brightness variations induced by topography, referred as topographic shadi…

3DPD: A photogrammetric pipeline for a PUSH frame stereo cameras
DOI: 10.1016/j.pss.2021.105165 Bibcode: 2021P&SS..19805165S

An innovative photogrammetric pipeline has been developed by INAF-Padova for the processing of the stereo images from the CaSSIS (Colour and Stereo Imaging System) (Thomas et al., 2014). CaSSIS is the multispectral stereo push frame camera on board ExoMars TGO (Trace Gas Orbiter) which will image 1.5% of the Mars surface in stereo mode with a spat…

CaSSIS Color and multi-angular observations of martian slope streaks
DOI: 10.1016/j.pss.2021.105373 Bibcode: 2021P&SS..20905373V

Slope streaks are albedo features that form frequently on equatorial Martian slopes. Most slope streaks are dark relative to surrounding terrains, a minor fraction is bright, and there are rare transitioning streaks that exhibit a contrast reversal partway downslope. Their formation mechanisms and physical surface properties are not well understoo…
