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.
NASA's Cassini captured these views of Saturn's icy moon Rhea on Feb. 9. The spacecraft returned to equatorial orbits around Saturn in March after nearly two years, allowing the mission to once again have close encounters with moons other than Titan.
The image on the left shows Cassini's view on approach to Phoebe, while the right shows the spacecraft's departing perspective. As it entered the Saturn system, NASA's Cassini spacecraft performed its first targeted flyby of one of the planet's moons.
