This illustration imagines the view from NASA's Cassini spacecraft during one of its final dives between Saturn and its innermost rings, as part of the mission's Grand Finale. Cassini made 22 orbits that swooped between the rings and the planet before ending its mission on Sept. 15, 2017, with a final plunge into Saturn. https://photojournal.jpl.nasa.gov/catalog/PIA22768
