Planetary topography measurement by descent stereophotogrammetry
Jones, G. H.; Brydon, G.; Persaud, D. M.
Digital Terrain Models (DTMs) provide valuable insights into the nature of solar system surfaces, facilitating geological analysis, landing site selection and characterisation, and contextualising in situ measurements. For missions to solar system bodies for which orbiters and soft landed platforms are technologically or financially challenging to…
Spectral classification and MGM-based mineralogical characterization of hydrated phases: The Nili Fossae case, Mars
Altieri, Francesca; Carli, Cristian; Serventi, Giovanna +2 more
Mars has a relatively tenuous atmosphere, the remote-sensed spectral data of the surface are affected by the presence of the atmosphere. In particular the water and CO2 absorption of the atmosphere are in the same spectral region as water, OH- and (CO3)2- in minerals. An accurate correction of the gaseou…
