The Cassini spacecraft beamed back this new,
more detailed image of smog-enshrouded Titan on June 14.
This view represents an improvement in resolution of
nearly a factor of three over the previous Cassini image release about Titan.
The observed brightness variations are real on scales of a hundred kilometers or
less.
The image was obtained in the
near-infrared through a polarizing filter. The combination was designed to
reduce the obscuration by atmospheric haze. The superimposed coordinate system
grid in the accompanying image at right illustrates the geographical regions of
the moon that are illuminated and visible, as well as the orientation of Titan
-- north is up and rotated 25 degrees to the left. The yellow curve marks the
position of the boundary between day and night on Titan.
This image shows about one quarter of Titan's
surface, from 0 to 70 degrees West longitude, and just barely overlaps part of
the surface shown in the previous Titan image release. Most of the visible
surface in this image has not yet been shown in any Cassini image
release.
The image was obtained with the narrow angle camera
at a phase, or Sun-Titan-spacecraft, angle of 61 degrees and at a distance
of 6.5 million miles (10.4 million kilometers) from Titan. The image scale
is 39 miles (62 kilometers) per pixel. The image was magnified by a factor of
two using a linear interpolation scheme. No further processing to remove the
effects of the overlying atmosphere has been performed.
The Cassini-Huygens mission is a cooperative project
of NASA, the European Space Agency and the Italian Space Agency. The Jet
Propulsion Laboratory, a division of the California Institute of Technology in
Pasadena, manages the Cassini-Huygens mission for NASA's Office of Space
Science, Washington, D.C. The imaging team is based at the Space Science
Institute, Boulder, Colorado.
