Panoramic Views and Landscape Mosaics of Titan

"Descent to Titan" Video in a new version

Home
On January 14, 2005, the European Space Agency's Huygens Probe parachuted through the Atmosphere of Saturn's Moon Titan, and even landed softly on a plain on its surface. A flood of scientific data was transmitted via the NASA's Cassini Orbiter to Earth, the most interesting ones being images of the landscape, that were obtained by the slowly spinning probe on its way through the hazy atmosphere of Titan. With the decision to make the raw data available to the public, the ESA made it possible for everyone with deeper interest to contribute to this historic space mission.
I personally concentrated on assembling the individual frames into Panoramic Views and Mosaic Images of the surface of Titan, so they become part of a larger context. The work was carried out in my rare leisure time, because of enthusiasm for this mission.





Video: Descend to Titan

Video: Descent to Titan, Version 2
An Animation of Huygens's view during its descent to the surface of Titan.
The Video contains rendered scenes of the landscape on Titan and the space probe as well as original images from Huygens.
This is a shortened, compressed version; the original animation was rendered in DVD quality.
MPEG-4 V2 compression *.avi - file, 8.2 MB
Descent to Titan, Version 1   ( 2.6 MB )

Rendered Views of Titan
My mosaic of the Huygens landing area on Titan, a POV-Ray model of Huygens as well as a simulated atmosphere is the basis for these images created with
POV-Ray.
The pictures shown here should be the most interesting for all visitors of my site who are not so intensively involved, or interested in the image-processing and mosaic-creating process of the Huygens mission.

Identifying Huygens landing site
The position of Huygens landing site as well as the correlation between the Huygens mosaic and the Cassini imagery is finally clear.
(+ links to my earlier attempts to figure out this correlation)

A Model for Hyperion
A little bit off-topic:
An attempt to explain the unique dark crater bottoms of Hyperion

Huge Surface Coverage Mosaic
The "Large Surface Coverage Mosaic" combined with "Huygens Distant View" results in a Mosaic with the largest coverage of Titan's surface that should be possible with Huygens images.

Huygens Distant View
A Panorama out of early, high altitude images from Huygens.
Not as vivid as the low altitude panoramic views, but it tells us a lot about the place Huygens landed.

Panorama of the prominent "Shoreline" on Titan

Panoramas out of low altitude DISR Side Looking Imager frames and an identification of Landscape Features visible in the Panorama as well as in the Mosaics.
