Abstract

We use thermochemical equilibrium calculations to show that SO is expected in volcanic gases erupted on Io, and derive the range of temperatures, pressures, and elemental compositions that provide the observed SO/SO₂ratio of 3-10% in Io's atmosphere. Our predictions could be tested during the Galileo Europa Mission (GEM), by Earth-based and Hubble Space Telescope observations in the millimeter and UV regions, or by a mass spectrometer and/or infrared spectrometer on an Io Volcanic Observer mission.
