The Cassini Plasma Spectrometer, CAPS, is an instrument aboard the Cassini orbiter primarily designed to detect thermal plasma throughout the Saturn system. The instrument has achieved this goal very successfully, and, as presented here, added to its immensely valuable scientific return by unexpectedly detecting positively and negatively charged nanodust in the upper atmosphere of Saturns largest moon Titan and in the plume of material ejected from the south pole of the icy moon Enceladus. Here, an overview is given of these observations, the sources of these particles, and the implications that their presence has for atmospheric chemistry at Titan, and the moon magnetosphere interaction that takes place at Enceladus.
