Water ice abundance and CO2 band strength on the saturnian satellite Phoebe from Cassini/VIMS observations

► Using Cassini-VIMS spectra, we map the water ice spatial abundance on Phoebe. ► The measured abundances are 0.1-4% with grain radii between 1 and 10 μm. ► We used dirty ice models to better fit Phoebe spectra. ► These models increase the measured spatial abundances by 1.6-12 times. ► We measured and mapped the strength of the CO2 band on Phoebe.
