The Cassini spacecraft performed its closest-ever flyby of Saturn’s moon Dione yesterday. In the above image, taken from a distance of 112,636 km from Dione, the moons Epimetheus and Pandora, as well as Saturn’s rings, can also be seen. This image was taken from a distance of 77,682 km. And this image reveals Saturn’s moon Mimas poking out from behind the dark side of Dione. Image credit: NASA/JPL/Space Science Institute; I added some sharpening and highlight correction.
