A unassuming civil servant named Cassini has spent 18 dutiful years poking about the cosmos. Her passport stamps – Saturn, Phoebe, Titan, Enceladus, and Venus, joined last week by Dione.
This view from NASA’s Cassini spacecraft looks toward Saturn’s icy moon Dione, with giant Saturn and its rings in the background, just prior to the mission’s final close approach to the moon on August 17, 2015. At lower right is the large, multi-ringed impact basin named Evander, which is about 220 miles (350 kilometers) wide. The canyons of Padua Chasma, features that form part of Dione’s bright, wispy terrain, reach into the darkness at left. Image credit: NASA

Cassini’s farewell to Dione allows for scheduled encounters with Enceladus on October 14, 18 and December 19. From December until mission conclusion in late 2017, Cassini plans to visit Daphnis, Telesto, Epimetheus, and Aegaeon, rounding out meticulous exploration of dignitaries among Saturn’s 63 or so moons.
