This seems like a good place to start off the Uranus and Neptune forum: with the next ice-giants mission.
I will admit to not knowing a whole lot about the Neptune Orbiter With Probes (NOWP), other than the fact that it's in the planning stages, and a few other details I've gathered from Wikipedia and various other Internet sources. Anyone care to get this one going with a bit more information? |

I suspect the 'lumpiness' of Iapetus is a result of a 'leisurely' formation period, time to radiate impact and radio-nuclide heat, too distant to have been warmed significantly from Saturnian formation heat, and also a very slow tidal braking effect from the the distant Saturn.
All these effects would allow for maximum thickness and strength of its crustal materials via cryogenic rigidity. |

I agree - it's not just a simple x-axis/y-axis graph, but a series of interconnecting variables, but with similar processes leading to similar outcomes...
