Psp_001385_1985_red.jpgUnnamed Crater, Boulders and Pseudo-Pyramids66 visiteMost debris on crater walls slides straight downhill. In this HiRISE image we see examples of boulders that have bounced downhill, not necessarily vertically.
A prominent example looks like a dotted line from the top of the crater wall where the boulder took off to the crater floor where it finally came to rest.
Numerous boulders have slid partway down toward the crater floor, which is covered by sand dunes. This is actually a small crater (~1 Km wide) within an unnamed but much larger ~30 Km crater.

Wispy_Star-PIA08875.jpgTwinkle, twinkle, Little Star...66 visiteCaption NASA:"The Cassini spacecraft gazes toward a distant star as Saturn's Rings slip past in the foreground. At upper left is the outer A-Ring, with its dark Keeler Gap. At lower right, a train of bright clumps shuttles past in the wispy F-Ring.
A temporal sequence of images like this allows Cassini scientists to correlate features in the rings with stellar occultation data acquired by other instruments. As the star passes behind the Rings, the changes in its brightness indicate how much empty space is between particles at different locations on the Rings.
This view looks toward the lit side of the Rings from about 56° below the Ring-Plane.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Dec. 30, 2006 at a distance of approx. 633.440 Km (such as about 393.686 miles) from Saturn. Image scale is roughly 4 Km (2 miles) per pixel".
