... 2012 November 6 . Methone: Smooth Egg Moon of Saturn . ... Explanation: Why is this moon shaped like a smooth egg? The robotic Cassini spacecraft completed the first flyby ever of Saturn's small moon Methone in May and discovered that the moon has no obvious craters. ... The smoothness and egg-like shape of the 3-kilometer diameter moon might be caused by Methone 's surface being able to shift -- something that might occur were the moon coated by a deep pile of sub-visual rubble . ...

... Dione's icy surface includes heavily cratered terrain, moderately cratered plains, lightly cratered plains, and whispy material. The heavily cratered terrain has numerous craters greater than 100 kilometers in diameter. ... Much of the heavily cratered terrain is located on the trailing hemisphere , with the less cratered plains area existing on the leading hemisphere . ... Because Dione is relatively small, an impact causing a 35 kilometer (21 mile) crater could have spun the satellite. ...

Note that Mimas is about 400 kilometers across (about 250 miles). ... The wall around the crater is 5 kilometers high, and that central peak rises 6 kilometers above the surface (many impact craters have a large central peak which is caused by a pressure rebound from the impact). ... 2008 Phil Plait. ...

The turret floor sits on a set of rollers bolted to the feed tower. The rolling surface sits between the bottom of the floor and the rollers. ... The plot shows the roll of the turret floor during a turret spin (.ps) ( .pdf) from 26 to 340 degrees and back (roll is in the direction of rotation). ... If there were 6 sections of rolling surface you might expect this spacing to be 60 degrees (or some beat of the 60 degree spacing and the spacing of the fixed rollers). ...
