This movie was created using to the data collected by the Huygens Descent Imager/Spectral Radiometer (DISR) on 14 January 2005, during the 147-minutes plunge through Titan's thick orange-brown atmosphere to a soft sandy riverbed.
Huygens Descent to Titan Surface
In 4 minutes 40 seconds, the movie shows what the probe saw within the few hours of the descent and the eventual landing. At first the Huygens camera just saw haze over the distant surface. The haze started to clear at about 60 kilometres altitude, making it possible to resolve surface features as large as 100 metres. Only after landing could the probe's camera resolve the smallest surface details down to little grains of sand.
