- Murray led the entire effort to use Cassini images to obtain astrometric data throughout the mission. The images were either of satellites against background stars, or mutual events where one satellite passed in front of another. Murray ensured that observations were requested, designed and subsequently reduced. When combined with historical observations, the Cassini astrometric data provided confirmation of the result that Saturn was much more dissipative than previously thought. Key Cassini observations of the moons Telesto, Calypso, Helene and Polydeuces (which Murray discovered) were essential in making an empirical determination of Saturn’s tidal Love number k_2.
