Looking closely at Saturn's moon Rhea during a somewhat distant flyby,
Cassini provides this view of what appears to be a bright, rayed and
therefore relatively young crater. This crater was also observed by
Cassini at much lower resolution in the fall of 2004 and in spring of
2005. Rhea is 1,528 kilometers (949 miles) across.
For comparison, viewing the same crater near the terminator (the line
between day and night) would highlight the crater's topography (vertical
relief), compared to its brightness, which is highlighted in this view
where the Sun is at a higher angle.
North on Rhea is up and rotated about 15 degrees to the left. This view
shows principally the leading hemisphere on Rhea.
The image was taken in visible light with the Cassini spacecraft
narrow-angle camera on April 14, 2005, at a distance of approximately
247,000 kilometers (153,000 miles) from Rhea and at a Sun-Rhea-spacecraft,
or phase angle of 70 degrees. Resolution in the image is 1 kilometer (0.6
mile) per pixel.
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 team is based at the Space Science
Institute, Boulder, Colo.
