We knew it years ago.

For a little while now there's been a bit going around about how this picture of Saturn's satellite Mimas resembles an item in a certain movie. This is amusing, but not for the reason that those posting it of late might claim.
The big crater, Herschel, on Mimas has been known about since 1980 or so. Cassini is not the first spacecraft to image Mimas. Voyager 1 got a picture and that has appeared a time or two.
With the Voyager 1 image which is a bit sharper rather than fuzzy, it's easier to distinguish the reality of a cratered moon.
