A major accomplishment during last year is the recongition of and modeling of the solid-state greenhouse effect for icy satellites. Recent observations of eclipse reappearances suggest that this effect may in fact be observed on Europa and Ganymede. Also the PI has obtained important new data on Europa and Enceladus. Evidence for the transient presence of a volatile, perhaps NH3, OH, on Europa has been obtained. Newly obtained spectra of Enceladus suggest that it does not at present have ammonia or methane in detectable quantities on its surface.
