Seems to be a lot of dispute on this subject... I think it's ice from the interior, but what does everyone else think?
Edit: This world seems very complex so the question could perhaps be phrased as 'which of these options is most responsible for the Iapetan dichotomy?' |

Like oDoug, I too noticed the apparent "duning" of dark material in some places; unlike him, didn't have the guts to mention it!
If this impression is true, then what the hell?! All I can think of is long-term outgassing that almost has to be recent & very local to the "dunes". Really want to see what the magnetometer read during this flyby; if anything's being emitted at all, that's the only shot we seemingly have of detecting it...(and, no, if any of this is really happening I have no feasible mechanism(s) to explain it...) -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.
