Titan's global map combining VIMS and ISS mosaics

Titan, Saturn’s largest moon, is the only ocean world, besides Earth, with a dense atmosphere. This outstanding feature is also a challenge since it was believed before the launch of the Cassini mission that optical cameras (visible and infrared) could not see the surface and that only radar instruments could map Titan’s surface. However, the Visual and Infrared
Mapping Spectrometer (VIMS) and the Imaging Science Subsystem (ISS) onboard the Cassini spacecraft demonstrated that Titan’s surface can be observed in several infrared atmospheric windows.
