Discussion: Rhea's Southern Pole

[Fraser]

SUMMARY: NASA's Cassini spacecraft took this picture of Rhea, one of Saturn's moons. The reasonably close view is of the moon's southern polar region which has been extensively cratered during its long history. Cassini acquired this view on July 14, 2005 when it made a close flyby, passing only 239,000 km (149,000 miles) away from the moon. The large, well-defined oval-shaped crater on the upper right is approximately 115 km (71 miles) across.

The overall appearance suggests that both Rhea and the impactors were less dense than the material of the inner solar system... I didn't see any 'rayed' craters, mostly smaller ones... the 'gash' is interesting; possibly a 'sideswipe'? or a localised surface response to a nearby impact? :huh:
