Stebbin's and Jacobsen's photoelectric measurements of the solar phase-brightness relationship for Jupiter's Galilean satellites are used to show that the surface layers of the satellites are very porous. The parameter that characterized relative density of a surface layer is equal to 0.2 for Callisto. Results of spectrophotometric observations of satellites are discussed briefly from the point of view of the possible nature of their surfaces.
