Cassini CIRS

The Cassini Composite Infrared Spectrometer (CIRS) consists of two spectrometers (far-Infrared and mid-Infrared). It measures the infrared energy from Saturn, its rings and its moons. CIRS observations of Saturn’s rings should determine the thermal structure of the the rings and provide insights into ring material composition and ring particle size.

Calibrated CIRS data from the Saturn encounter is now available in two formats. See the About CIRS Data Tab for information about the formats.
