The background ring material displays some azimuthal (i.e., left to right) asymmetry.</p><p>The radial (outward from Saturn) direction is up in this view. A noticeable kink in the spoke occurs very close to the radius where ring particles orbit the planet at the speed of Saturn's magnetic field. Such a connection is most intriguing to scientists studying these ghostly ring phenomena.</p><p>If gravity alone were affecting the spoke material, there would be no kink and the entire spoke would be angled toward right, like the bottom portion. That it bends to the left above the kink indicates that some other force, possibly related to the magnetic field, is acting on the spoke material. The shape might also indicate that the spoke did not form in a radial orientation, thus challenging scientists' assumptions about these features.</p><p>This view looks toward the unlit side of the rings from about 58 degrees above the ringplane.</p><p>The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Jan. 23, 2007 at a distance of approximately 1.6 million kilometers (1 million miles) from Saturn.

Pan is closer to Saturn, and thus orbits faster, and Pan overtakes Daphnis every 19 days.</p><p>The flying-saucer-like shape of Pan (26 kilometers, or 16 miles across) can easily be discerned here. Daphnis (7 kilometers, or 4.3 miles across) is a mere speck, although its presence is made obvious by the edge waves it creates in the surrounding ring material.</p><p>Pan also raises waves in the edges of the Encke Gap (see <a href="/catalog/PIA06099">PIA06099</a>). However, even though Pan is more massive than Daphnis, Pan is farther from the edges of its gap than the smaller moon. This causes Pan's edge waves to have a much longer wavelength (they are more stretched out) and a smaller amplitude (they do not extend as far inward from the gap edge) as those created by Daphnis, making them more difficult to see.</p><p>This view looks toward the sunlit side of the rings from about 24 degrees below the ringplane.</p><p>The image was taken in visible light with the Cassini spacecraft narrow-angle camera on March 24, 2007 at a distance of approximately 889,000 kilometers (553,000 miles) from Daphnis and at a Sun-Daphnis-spacecraft, or phase, angle of 21 degrees.

The inner rings partly obscure the planet at top.</p><p>The image was taken with the Cassini spacecraft wide-angle camera on July 12, 2005 at a distance of approximately 1.5 million kilometers (900,000 miles) from Saturn. The monochrome view uses a combination of images taken using spectral filters sensitive to wavelengths of light centered at 728, 752 and 890 nanometers. Image scale is 170 kilometers (105 miles) per pixel.</p><p>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 operations center is based at the Space Science Institute in Boulder, Colo.</p><p>For more information about the Cassini-Huygens mission visit <a href="http://saturn.jpl.nasa.gov">http://saturn.jpl.nasa.gov/home/index.cfm</a>.
