Many thanks for the advices on converting the Iapetus-map from 0° to 180° center.
I will try when time allows... Back to Iapetus... ...I found these two 'old' Cassini images back from July 19, 2004: Distance: ~ 2.9 Mio. km Resolution: 17 km/pxl A first hint on what we'll see in the upcoming far-encounter. Visible is the bright southern rim of the big bassin in eastern CR and the polar region with a large amount of craters below. Actually what is the dark curved structure parallel to the terminator? The eastern rim of another big bassin? There also seems to be a greater structure - possibly a crater - left to the terminator south of this dark bow. Bye. |
