Raw Images -- Rhea Flyby, Jan. 11, 2011
|Shadowy Rhea Craters
This raw image obtained by NASA's Cassini spacecraft of Saturn's moon Rhea shows an old, cratered surface seen with a low sun angle, casting deep shadows on the crater floors. Cassini's wide-angle camera was about 100 kilometers (60 miles) away from Rhea's surface.
|Cross-Cutting Faults on Rhea
NASA's Cassini spacecraft obtained this image of the surface of Saturn's icy moon Rhea during its closest flyby of the moon. Rhea's surface is scarred by many craters and several long, cross-cutting faults. These faults – and the presence of so many craters -- show Rhea may have had some activity early in its geological history, but never developed the full-blown activity seen on other moons in the Saturn system. This raw image was taken by Cassini's narrow-angle camera on Jan. 11, 2011, from approximately 41,000 kilometers (25,000 miles) away.
In this image obtained by NASA's Cassini spacecraft on its closest flyby of Saturn's moon Rhea, the heavily cratered surface of the moon appears in great detail. Just to the bottom right of the center of this image, a bright area appears to indicate a freshly excavated double crater. Double craters can appear when two gravitationally linked asteroids crash into a surface. This image was obtained by Cassini's narrow-angle camera on Jan. 11, 2011, from a distance of about 20,000 kilometers (12,000 miles) away.
