Titan's polar collar
  Titan's polar collar -- previously seen by Voyager 2 and the Hubble Space Telescope -- has now been observed by the Cassini spacecraft, seen here in ultraviolet light. The collar is believed to be seasonal in nature. Researchers are still studying its cause and evolution. Image released Aug. 26, 2013.

T-95: A Visit at Noon

This was a highly inclined flyby, with closest approach near the equator, providing coverage of the equatorial region out to both mid Northern and Southern latitudes. With closest approach in the noon region during a period of high solar activity, this was the best pass in the Solstice mission to study the effects of solar input on Titan’s atmosphere.

This flyby was also in the outer flank of the Titan magnetospheric interaction region, which made it an excellent opportunity to study both the effects of solar activity on the magnetospheric boundary as well as seasonal change.

Radar had ride-along synthetic aperture radar (SAR) running north to south east of Adiri, across Selk impact structure, and high synthetic aperture radar (HiSAR, a method like SAR that can be used when the target is too far away or at the wrong angle for conventional SAR) of Ontario Lacus and margins of Ligeia Mare for change detection. Inbound there was an opportunity for HiSar and altimetry, and outbound had planned scatterometry/radiometry, HiSAR and altimetry.
