T-53 Flyby: Studying Titan's Atmosphere With Ultraviolet Light

During its April 20 flyby's closest approach, Cassini took advantage of a rare opportunity to measure extreme ultraviolet emissions, as the Ultraviolet Imaging Spectrograph (UVIS) observed solar and stellar lights through Titan's atmosphere.

The Composite Infrared Spectrometer (CIRS) obtained high-resolution coverage of the edge of the moon. The Imaging Science Subsystem (ISS) teamed up with the Virtual and Infrared Mapping Spectrometer (VIMS) to image Titan’s trailing hemisphere at high southern latitudes and with CIRS to monitor clouds.
