CICLOPS: Cassini Imaging Central Laboratory for OPerationS

Phoebian Explorers
[For trouble viewing the images/movies on this page, go here]
These two montages of images of Phoebe taken by Cassini in June 2004 show the names provisionally assigned to twenty-four craters on this Saturnian satellite by the International Astronomical Union.

The crater names are those of the Argonauts, explorers of Greek mythology who sought the golden fleece. Argo was the name of their ship. Appropriately, the largest crater, approximately 100 kilometers (62 miles) across, is named after the leading Argonaut, Jason. Phoebe is an outer moon of Saturn and is 214 kilometers (133 miles) across.

The two-image montage (PIA 06117) displays mosaics made of individual, very high resolution images: 80 meters (260 feet) per pixel on the left; 200 meters (660 feet) per pixel on the right.

The other montage (PIA 06118) shows eight images of much lower resolution, ranging from 0.5 to 1 kilometer (0.3 to 0.6 mile) per pixel. The images in this montage show Phoebe as it rotated, and include regions of the moon not visible in the higher resolution montage.

The images have been slightly rescaled from their original formats and contrast-enhanced.

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 Science Mission Directorate, Washington, D.C. The imaging team consists of scientists from the US, England, France, and Germany. The imaging operations center and team lead (Dr. C. Porco) are based at the Space Science Institute in Boulder, Colo.
