The Cassini narrow angle camera took images of the ropy, taffy-like
topography of Saturn's moon Enceladus from many different angles as the
spacecraft flew by on Feb. 17, 2005. Images from different directions
allow construction of stereo views such as this, which are helpful in
interpreting the complex topography.
This view of an area about 60 kilometers (37 miles) across shows several
different kinds of ridge-and-trough topography, indicative of a variety
of horizontal forces near the surface of this 505-kilometer (314-mile)
diameter satellite.
Several different kinds of deformation are visible, and a small population
of impact craters shows that this is some of the younger terrain on
Enceladus. Sunlight illuminates the scene from the bottom.
Interestingly, the topographic relief is only about one kilometer, which
is quite low for a small, low-gravity satellite. However, this is
consistent with other evidence that points to interior melting and
resurfacing in Enceladus' history.
The images for this anaglyph were taken in visible light with the narrow
angle camera, from distances ranging from 10,750 kilometers (6,680 miles,
red image) to 24,861 kilometers (15,448 miles, blue image) from Enceladus,
and at Sun-Enceladus-spacecraft, or phase, angles from 32 to 27 degrees.
Pixel scale in the red image is 60 meters (197 feet) per pixel; scale in
the blue image is 150 meters (492 feet) per pixel. The images have been
contrast-enhanced to aid visibility.
A separate, non-stereo version of the scene, showing only the red image
is also available (see PIA06190).
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 mission for NASA's Science Mission Directorate,
Washington, D.C. The Cassini orbiter and its two onboard cameras were
designed, developed and assembled at JPL. The imaging team is based at
the Space Science Institute, Boulder, Colo.
