Cassini's combined infrared spectrometer instrument will be probing Titan's stratosphere to study more about its vertical structure as the seasons change. Equinox, when the sun shone directly over the equator, occurred in Aug 2009, and the northern hemisphere is now in spring.

Cassini's visible-light imaging cameras will also be taking images of Titan's trailing hemisphere, or the side that faces backward as Titan orbits around Saturn. If Titan cooperates and has a cloudy day, scientists plan to analyze the images for cloud patterns.
The Cassini-Huygens mission is a supportive project of NASA, the European Space Agency and the Italian Space Agency. JPL, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington, D.C.
