The Rosetta space mission explored comet 67P/Churyumov-Gerasimenko between July 2014 and September 2016. During two years, extensive mappings in the visible and infrared ranges have been achieved by the VIRTIS imaging spectrometer (Visible InfraRed T

Geometric preprocessing for Rosetta/VIRTIS-M measurements of comet 67P/C-G

Autor: Kappel, David, Arnold, Gabriele, Moroz, Liubov, Raponi, A., Ciarniello, M., Tosi, F., Erard, S., Leyrat, C., Blecka, M., Filacchione, G., Capaccioni, F.

Following earlier surface spectrophotometric analyses of Rosetta/VIRTIS-M measurements of comet 67P/Churyumov-Gerasimenko (hereafter 67P), we refine the instrument's geometric registration model and spatial consistency of the radiometric calibration.

International audience; We have used the latest available shape model for gas and dust simulations of the inner coma of comet 67P/Churyumov-Gerasimenko for the period around May 2015 (equinox). We compare results from a purely insolation-driven model

Mass movements are almost ubiquitous in the Solar System, with rockfall, avalanches or landslides that are observed not only on Earth, but also on multiple other bodies. The characteristics of the observed landslides (i.e. type of failure, geometry,
