Nanodust Measurements by the Cassini Plasma Spectrometer

Part of the Astrophysics and Space Science Library book series (ASSL, volume 385)


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.

The Cassini Plasma Spectrometer team was designed, built, and operated by an international team led at the Southwest Research Institute, San Antonio, Texas (Principal Investigator: F. J. Crary). The author is supported by a UK Science and Technology Facilities Council Advanced Fellowship, and is grateful for useful discussions with C. S. Arridge, A. J. Coates, and A. Wellbrock.
