Dunes were seen on Mars and Venus, even on early satellite images. As the resolution of the imagery improved, Mars was seen also to have ripples (not surprising in view of the presence of dunes), but then, at even better resolution and quite unanticipated, transverse aeolian ridges were discovered, which are unique to Mars. Even more surprising was the still later discovery of linear dunes on Titan, the biggest of Saturn's moons, in 2006. The apparent freshness of the Titan's dunes suggests that they are recent, which raises questions about the relationship of sand production to orbital cycles.
