cassini flies just 76km above rhea surface on jan. 11

It's an exciting time for Cassini imaging team scientists as the spacecraft drops to just 47 miles above the surface of Rhea, Saturn's second largest moon, on January 11th!  "These will be by far the best images we've ever had of Rhea's surface - details down to just a few meters will become recognizable," said Thomas Roatsch, a team scientist at the German Aerospace Center Institute of Planetary Research in Berlin.  "New Images Indicate Tectonic Activity On Rhea ", a brief article at Space Daily, reveals sharp fractures on the Saturn moon's surface--an indication of tectonic activity.  Cassini will continue to chart the terrain of Saturn's moons until 2017.
