This movie, created with data collected during Huygens's mission at Titan on 14 January 2005, shows the operation of the DISR camera during its descent up to touch-down. The almost 4-hour long operation of DISR is shown in less than five minutes - 40 times the actual speed up to landing and 100 times the actual speed thereafter (for a complete description see the pdf file "DISR Descent Details" on the right-hand side).
DISR Operations During Descent
The first part of the movie shows how Titan appeared to DISR as it acquired more and more images during the probe's descent. Each DISR image has a small field of view, and dozens of images were made into mosaics of the whole scene.
The scientists analysed Huygens' speed, direction of motion, rotation and swinging during descent. The DISR movie includes sidebar graphics that show:
The sounds indicate different activities. Full details can be found in the pdf file "DISR Descent Details" on the right-hand side.
