T-54 Flyby: Sensing Titan's Atmosphere

As the Cassini spacecraft approached Titan during its May 5 flyby, the Composite Infrared Spectrometer (CIRS) focused on the moon's atmosphere, analyzing its temperature and aerosol profiles.

The Imaging Science Subsystem (ISS) acquired high-resolution imaging of Titan’s trailing hemisphere at high southern latitudes and rode along with the Visible and Infrared Mapping Spectrometer (VIMS) to monitor clouds. The Radio and Plasma Wave Science (RPWS) instrument measured thermal plasmas in Titan's ionosphere and surrounding environment, searched for lightning in Titan's atmosphere, and investigated the interaction of Titan with Saturn's magnetosphere.
