Now in its eleventh year in orbit around Saturn, the ESA/NASA Cassini spacecraft is delivering new images of Saturn’s moons. It moved to a more equatorial orbit in March, after two years in high orbit above the polar regions. This brings its back in range of Saturn’s moons, and the transition is marked by a stream of new pictures.
In February, Cassini sent back some of the clearest images of Rhea, taken from 30,000 to 50,000 miles away. Rhea is Saturn’s second-largest moon, and had the distinction of being the most heavily-cratered body in the solar system. This is an indication of its great age.
