Cassini Samples Titan's Atmosphere

On March 25, just prior to its closest approach at an altitude of 1,000 kilometers (620 miles), Cassini employed its Ion and Neutral Mass Spectrometer to examine Titan's upper atmosphere in yet another successful flyby of the orange-tinged moon. Immediately after closest approach, the spacecraft's Visual and Infrared Mapping Spectrometer captured images of Titan near the Huygens landing site.
