Beautiful mosaic of the Voyager mountains

One of my favorite amateur image magicians, Gordan Ugarkovic continues to play
around
with the amazing data recently released by the Cassini mission, covering the
Iapetus
encounter of last September. Here's a lovely mosaic he just put together of the
Voyager
Mountains. You can see my puny effort at this mosaic, using just the raw data,
here -- but
below is what happens when an artist gets his hands on the real data.
Just after its closest approach to Iapetus on September 10, 2007, Cassini
focused
downward to capture a six-frame color mosaic of the "Voyager Mountains," a line
of peaks
first spotted in images from the Voyager spacecraft as a series of white spots
marching
along the equator into the dark terrain. The data was released to the Planetary
Data
System in June 2008; here, amateur Gordan Ugarkovic has assembled the mosaic, in
color,
and overlaid it on a wide-angle shot taken at the same time to provide context.
The color
is slightly different between the narrow- and wide-angle mosaics: narrow-angle
is IR1-
GRN-UV3, while wide-angle is IR1-GRN-VIO. The mosaic is shown here at half its
full
resolution; visit Ugarkovic's Flickr photostream to download the full-resolution
version.
