[Moderator's note: This thread contains images from the Iapetus 2007-09-10 flyby and discussion of them. It was created by splitting this thread which contains pre-flyby discussion]
Another CL-UV3-GRN-IR1 set was posted today, though Iapetus seems to have been hiding from the green and IR filters...here's my best effort at making something from the CL and UV3 images. Lots of topography on the limb! --Emily -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.

Is it me or does Iapetus' surface look different than other icy moons at this scale? The surface is saturated with big craters and then peppered by very small ones at certain locations. It almost looks like it's missing "intermediate" crater sizes. Another thing in that picture is the bright terrain near the horizon, is that the transition region?
Fascinating and very crisp imagery, considering the difficulties with exposure for dark material at high phase angle. So far only UV3 frames were underwhelming, but that might change as well as phase angle rapidly decreases after C/A. Can't wait to see the Voyager mountains pop up. EDIT: Regarding bright terrain, nevermind. Just looked up Tilmann's page and yes the limb shot catches a bit of northern transition zone. -------------------- |
