What does the surface of Saturn's moon Rhea look like? To help find out, the robot Cassini [ http://saturn.jpl.n…] spacecraft currently orbiting Saturn [ http://www.nineplan…] was directed to fly right past the second largest moon of the gas giant planet [ http://antwrp.gsfc.…] late last month.

The rim of an old crater crosses the middle of the image, with many smaller and younger craters [ http://en.wikipedia…] scattered throughout. A linear [ http://en.wiktionar…] depression -- possibly a tectonic fault [ http://www.extremes…] -- is visible toward the right, crossing the likely loose material that composes Rhea's surface regolith [ http://antwrp.gsfc.…].
