Cassini
Titan Flyby (T-54) - May 5, 2009

T-54 Flyby: Sensing Titan's Atmosphere

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

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