Voyager 2 made its closest approach to Saturn 35 years ago -- on Aug. 25, 1981. What the Voyagers revealed at the planet was so phenomenal that, just one year later, a joint American and European working group began discussing a mission that would carry on Voyager's legacy at Saturn.
That mission -- named Cassini -- has been studying the Saturn system since 2004. Cassini has followed up on many of Voyager's discoveries, and has deepened our understanding of what some might call a "mini solar system.” Up-close views from the Voyagers, like this one from Voyager 2, showed Saturn and its rings as never before.
