Galileo


The primary mission goals of the Galileo Mission were to study the chemical composition of the Jovian atmosphere and satellites, and to study the magnetotail. In particular, the probe was going to measure the molecular, elemental and isotopic composition of the atmosphere, composition of the cloud particles, circulation and dynamics, heat balance and the temperature and pressure structure. The goal of the satellite observations was to look at the geological evolution, mineral distribution, gravitational and magnetic fields, existence of atmospheres, and to study the interaction of the satellites with the Jovian magnetosphere. The extended Europa mission will not only fly by Europa 7 more times, but includes 4 Calliso encounters, and a couple close Io flybys. The goal of the extended mission is a focused follow-on which will also serve as preparation for future Europa missions. The major objectives include a characterization of the crust, atmosphere and possible ocean of Europa, and to map the Io plasma torus while an intensive investigation of the volcanic processes on Io are ongoing.
