SSTONE is a database on “spectroscopy of solids and ices” of planetary interest. It uses various types of spectroscopic techniques: Visible and Near Infrared bidirectionnal reflectance of granular or compact surfaces, microscopy of grains, Raman scattering. Spectra are acquired directly on the field or in the laboratory in various environmental conditions: terrestrial or analogous planetary conditions (low to high temperature, low to high pressure, gas phase, …). These data are mainly used for improving the interpretation of orbital or in-situ planetary spectra on rocks, minerals and ices, but also for terrestrial data. The database currently contains: (1) NIR reflectance spectra of ice mixed with various concentration of sulphate and (2) NIR reflectance spectra sands wet with pure water (various origins and compositions) at different steps of drying. The database will contain soon: Raman spectra of volcanic glasses and icy moons analogous clathrates, NIR reflectance spectra of olivine altered in martian conditions and of pure water ice at different temperatures and grain sizes.
