This session invites presentations on the atmospheres and exospheres of satellites around giant planets. Papers relevant to Titan’s atmosphere, the exospheres of Enceladus, Io, Triton and other moons are welcome. Observations from space missions like Cassini, Galileo, etc, as well as from Earth-based observatories are most welcome, as are results from laboratory and theoretical work performed to help in the analysis and interpretation of measurements.
