This image provides a comparison between the Huygens landing site on Titan as viewed by the Cassini Imaging Science Subsystem and the NACO/SDI instrument mounted on the 8-meter Yepun telescope of the Very Large Telescope in Chile.
From the two images it is possible to see a high consistency between the two measurements. The Cassini image – taken in the near-infrared (938 nanometers)- shows the Huygens landing site map wrapped around Titan, rotated to the same position as the January 2005 NACO/SDI observations.
The colored lines outline the regions imaged by Cassini at different resolutions. The lower-resolution imaging sequences are outlined in blue.
Other areas have been specifically targeted to build moderate and high resolution mosaics of surface features. These include the site where the Huygens probe has touched down Jan. 14, 2005, marked with the yellow X, and located at 10.3 degrees south latitude and 192.32 degrees west longitude (or 167.7 degrees east).
The landing site is located on the boundary between the bright region called Adiri and the dark one called Shangri-la.
The red color on the NACO/SDI image corresponds to an atmospheric filter at 1.625 micron, while the blue color represents a filter for the surface at 1.600 micron and 1.575 micron.
