Dione was first imaged by the Voyager space probes. It has also been probed three times from closer distances by the Cassini orbiter. There was one close targeted fly-by, at a distance of 500 km on 2005 October 11; another similarly close fly-by was performed on 2010 April 7. A third fly-by was performed on 2011 December 12 at an altitude of 99 km.
