Posted by Emily Lakdawalla on 2014/07/04 12:04 CDT | 4 comments

As Cassini celebrates 10 years at Saturn, we're beginning to see its long-term observations of Saturnian moons bear fruit. A surprising new result: While Prometheus exerts control over the F ring and Atlas, Pandora -- long thought to be a shepherd of the F ring -- does not.

ARM would launch U.S. explorers into deep space beyond the Moon, and fits logically into an exploration program aimed at Mars.
