The Jupiter system

  • Ronald Greely


Voyager 1’s dramatic 1979 flyby of Jupiter and its satellites doubled the number of objects available for geologic analysis. Prior to that time, only the surfaces of Earth, Moon, Mercury and Mars were known. Voyager, for the first time, revealed the complexity and diversity of Jupiter’s major satellites and provided tantalizing clues to their surface histories. The features seen on the satellites prompted a re-examination of traditional geologic processes. The new data caused planetologists to consider such bizarre processes as volcanism driven by sulfur compounds, fracturing of ice-rich planetary crusts, and flooding of surfaces by liquid water.
