Especially one so little. (this is False Colour. Really this is a sooty black body, with redbrown ooze at the bottom of the craters, and a water ice white frosting on the peaks of some of the high ridgetops) Most of the craters seem just like a bed of hydrothermal vents in a high energy flux geothermal area to me. The assertion that its only the surface layer up to 12 inches thick that is dark black carbon covered/coloured, except for some white ice highlights on the extremities of some crater rims, "which must be the real ice composition of the 200km of material below" seems tenouous to me. The "Dark red gunge at the bottom of many craters, consisting of mainly long chain hydrocarbons" is a big curiousity. As Well as: the "Chaotic rotation", the axis of rotation is constantly changing "unpredictably" in this 200km dia moon. The 4:3 orbital resonance with Titan (the most planet earthlike moon in the solarsystem) is troubling. Apparently it has the sort of stability of a rock balanced on a knife-edge. Could not have formed there or evolved into that orbital configuration. Anyone have opinions on this? what about the layer of smokey residue on the leading edge of iepetus, the next moon outwards, said to be the same colour and composition of Hyperions surface?
