Titan Surface Mosaic
This stereographic projection of Descent Imager/Spectral Radiometer images from the ESA's Huygens probe combines 60 images in 31 triplets, projected from a height of 3000 metres above the black 'lakebed' surface. The bright area to the north (top of the image) and west is higher than the rest of the terrain, and covered in dark lines that appear to be drainage channels.
The images were stitched together using one of several projection algorithms (in this case 'stereographic') to produce a full mosaic. The images used to construct this mosaic were taken on 14 January 2005.
The Descent Imager/Spectral Radiometer is one of two NASA-funded instruments on the Huygens probe.
The Cassini-Huygens mission is a cooperative project between NASA, ESA and Italy's ASI space agency.
