CIRS dives on Saturn: the ultimate end of the smallest instrument of the Cassini probe

The Cassini probe will finish this September 15, 2017 its mission of more than 13 years around Saturn. On board, the smallest instrument, a detector only 5 millimetres long, was developed by the Department of Astrophysics of CEA-Irfu, which carried it out in collaboration with CEA/LETI (Electronics and Information Technology Laboratory). This detector, which is at the heart of the CIRS (Composite InfraRed Spectrometer), has made it possible to measure the temperature of Saturn's rings with an unequalled resolution and has also made it possible to discover many molecules in the atmosphere of Saturn and its Titan satellite.
