PDS Information
Find a Node - Use these links to navigate to any of the 8 publicly accessible PDS Nodes.

This bar indicates that you are within the PDS enterprise which includes 6 science discipline nodes and 2 support nodes which are overseen by the Project Management Office at NASA's Goddard Space Flight Center (GSFC). Each node is led by an expert in the subject discipline, supported by an advisory group of other practitioners of that discipline, and subject to selection and approval under a regular NASA Research Announcement.

This ultraviolet view shows wavy cloud bands near Saturn's south polar region. Though the region has some visible features, strong contrast between light and dark cloud bands is notably absent, as are bright and dark spots.

The eye is drawn to a bright wedge near the lower-left limb (apparent edge) of the planet. That wedge falls in a latitude band that borders a darker latitude band a little closer to the pole. Viewing the limb of the planet in ultraviolet light allows scientists to study the high part of the atmosphere (the stratosphere). Scientists can discern from this image that the stratosphere in this latitude band is relatively pure hydrogen and helium and contains very little of the stratospheric haze that causes darkening closer to the pole.

This view was taken with the Cassini spacecraft narrow angle camera on July 21, 2004, at a distance of 6.4 million kilometers (4 million miles) from Saturn. The image scale is 38 kilometers (23 miles) per pixel. The image was taken using a spectral filter centered at 298 nanometers, and reveals different details in the gas giant's atmosphere than those seen in longer wavelengths. Contrast was slightly enhanced to bring out features in the atmosphere.

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 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.
