Abstract

Our knowledge of Io has progressed dramatically in the past year. Prior to 1973, observations of Io made at optical, IR and radio wavelengths have revealed that this innermost Galilean satellite of Jupiter is unusual in a number of ways. A list would include post-eclipse brightening, high near-IR albedo, puzzling features (or lack of features) in the reflection spectrum, discordant brightness temperatures measured at 10 and 20 μm, and modulation of Jovian decametric activity. We now understand that Io has an atmosphere and an ionosphere. Their presence and interaction with the Jovian magnetosphere may account for much of the unusual behavior of the enigmatic satellite.
