Close up surface features of U&N:s satellites, discussion thread (obviously, no close up photos exists) Options

Hi all,

This has perhaps been asked before but since many of Uranus' and Neptune's satellites have many similarities in material composition (most are mainly rock + water ice), how much can be known about small scale features of their surfaces? How accurate would a procedurally estimated terrain patch of, say, 1x1km be. How about 100x100m? 1x1m?

I began thinking about this going through the imagery from Philae/Rosetta on 67P/Churyumov–Gerasimenko. Since 67P/Churyumov–Gerasimenko consists largely of water ice, like many of U&N satellites surfaces (even though many are ~50/50 rock/ice, the moons surfaces should be more ice because of cryo-volcanism from what I understand), we could perhaps take a lot of inspiration from those photos. How would U&N moons differ from 67P/Churyumov–Gerasimenko on a detailed scale? I am specifically doing a project about Uranus' Miranda but since the topic may apply to many of the satellites, feel free to discuss others too!

Some of the 67P/Churyumov–Gerasimenko imagery:

Great throughts! I had not thought about PC-G winds/evaporation as "erosive forces", but that may explain some of the features of the comet.
