CICLOPS: Cassini Imaging Central Laboratory for OPerationS
Rugged Mimas

The oblate moon Mimas displays the cratered surface of its anti-Saturn side.

North on Mimas (396 kilometers, 246 miles across) is up and rotated 1 degree to the left. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Nov. 22, 2009. The view was acquired at a distance of approximately 588,000 kilometers (365,000 miles) from Mimas and at a Sun-Mimas-spacecraft, or phase, angle of 63 degrees. Image scale in the original image was 4 kilometers (2 miles) per pixel. The image was contrast enhanced and magnified by a factor of 2 to enhance the visibility of surface features.

The Cassini Equinox Mission is a joint United States and European endeavor. 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 was designed, developed and assembled at JPL. 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.

A side note: On february 13th there will be a Mimas flyby at 10 000 km/ 6 000 miles. That's not a close one, but still about 6 times closer than the 2005 Mimas flyby.

Congratulations to the new SOLSTICE MISSION !

Cool image but like this one too"Before a Veiled Rhea", composite image of Mimas and Rhea,

Way to go Ciclps, mission extension Solstice to 2017!!
Next encounter is a Rhea flyby in 26 days....

Cool, but I prefer "Herschel: Dead On" ( Really dramatic.


Thanks to all those hard-working people who have made it possible
