Mimas (246 miles or 396 kilometers across) is the more noticeable of the two moons and is in the top left of the view. The smaller moon Prometheus (53 miles, or 86 kilometers across) is near the center of the image and is closest to Cassini. Mimas is beyond the rings and farthest from the spacecraft. Lit terrain seen on Mimas is on the leading hemisphere of the moon. This view looks toward the northern, sunlit side of the rings from just above the ringplane.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera. The view was acquired at a distance of approximately 746,000 miles (1.2 million kilometers) from Prometheus and 870,000 miles (1.4 million kilometers) from Mimas. Image scale is 4 miles (7 kilometers) per pixel on Prometheus and 5 miles (8 kilometers) per pixel on Mimas.”
“After almost 20 years in space, NASA’s Cassini spacecraft begins the final chapter of its remarkable story of exploration: its Grand Finale. Between April and September 2017, Cassini will undertake a daring set of orbits ...
