ESPLORAZIONE DEL SISTEMA GIOVIANO
Prima missione a orbitare Giove. Lanciata nel 1986. (Doveva lanciare nei primi anni 80 ma ritardo per Challanger)
L’antenna principale non ha funzionato ma hanno usato l’antenna principale e compressione dati

A GLOBAL WEB OF FLY-BYS
-Multiple satellite gravity assists enables
“global-regional coverage” of Europa from
orbit around Jupiter-Current mission design consists of nearly 50
low-altitude Europa flybys over 3.5 years-Minimizes time in high radiation environment-Simple repetitive operations
