Scientific Colloquium
October 15, 2004

Galileo’s seven-year plus mission in the Jupiter system has ended, but its rich scientific legacy lives on.  During the course of the mission, Galileo’s observations profoundly altered our thinking about the Jupiter system and the giant planets of the outer solar system.  Dr. Johnson, who led the Galileo science team as Project Scientist throughout the project’s development and operations, will review the major discoveries from the mission, including: Probe results on the composition of Jupiter, satellite magnetic fields, Io’s super-hot volcanism and evidence for global oceans below the icy crusts of Europa, Ganymede and Callisto. These results have set the agenda for future exploration of Jupiter and the satellites and are providing the context for interpreting the data now coming from the Cassini/Huygens mission in the Saturnian system.
