Mimas briefly slipped in front of Tethys while the Cassini spacecraft
looked on and captured the event in this series of images.
The images were taken in visible light with the Cassini spacecraft
narrow-angle camera on Feb. 11, 2006, at a distance of approximately 3.7
million kilometers (2.3 million miles) from Mimas and 4.1 million
kilometers (2.5 million miles) from Tethys. Resolution in the original
images was 22 kilometers (14 miles) per pixel on Mimas (397 kilometers,
or 247 miles across) and 25 kilometers (16 miles) per pixel on Tethys
(1,071 kilometers, or 665 miles across). The images have been magnified
by a factor of two.
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.
