The view was acquired at a distance of approximately 2,280 miles (3,670 kilometers) from Rhea and at a Sun-Rhea-spacecraft, or phase, angle of 92 degrees. Image scale is 72 feet (22 meters) per pixel.”

Between April and September 2017, Cassini will undertake a daring set of orbits that is, in many ways, like a whole new mission.
