Аннотация доклада:
Weak absorption bands with relative intensity ~1-10% are found for the first time in the visible-range reflectance spectra (RS) of Galilean icy satellites of Jupiter, Europa, Ganymede and Callisto. It seems, several of the bands are common for the bodies and may be manifestations of adsorbed O2 for radiation implantation of O+ ions into the satellite surface in the magnetosphere of Jupiter. Specific ones could be produced by iron ions (Fe2+ and Fe3+) in silicates on Ganymede and Callisto and by methane adsorbed in water ice on Europa.
