Rev 46 description available at CICLOPS
http://ciclops.org/view.php?id=3245 Some highlights: Cassini will observe Mimas, the innermost of the mid-sized icy satellites of Saturn June 12, Cassini makes one of its closest passes of the small, inner satellite Atlas, at a distance of only 38,000 km (24,000 mi). With an average diameter of only 31 km (19 mi), Atlas is one of the smallest moons of Saturn. Atlas will only appear to be 120 pixels across (at the equator). However, these images may still provide important clues about the formation of one of the most distinguishing aspects of the tiny satellite: its equatorial bulge. The bulge is thought to have been created by material from Saturn’s A ring being deposited preferentially along the equator of the satellite. A number of observations are dedicated to observing some of Saturn's small moons, in order to refine scientists' estimates of their orbital paths. These sequences include observations of some of Saturn's outer satellites, such as Paaliaq, Hati, and S/2004 S13 I've seen a few of these small outer moons listed recently on the raw image page. They search tool only shows them from the last few orbits. Is this something new they are doing or have they been previously listed as Sky? |

Just curious musing here:
Would an impact into the accumulated dust donut knock off quite a bit of it, and then might it go back into orbit around Saturn and then re-accrete (re-re-re-accrete ??) back on to Atlas? Cool if we have a recursive phenomena here. Is the process of re-accretion going on right now ?? |
