So,
next series arrived... Here two further takeouts, ~4x enlarged: Date:2007-04-17 Distance: 2,310,887 km Filters: CL1 and GRN Date:2007-04-18 Distance: 2,334,981 km Filters: CL1 and CB2 Interesting craters near the terminator in the northern hemisphere getting more and more visible now... The huge step/rim in the north polar region is still recognizable - there even seems to be a kind of mountain near the pole at the disk rim there! And still the bright patches at the sunlight equator region of Roncevaux Terra ... Bye. |

I'd rather say 'tennis ball moon'- more three dimensional and less philosophical baggage.

TritonAntares I've just created a cross-eye stereo pair from two of your recent images by photocopying them at 50 and 42 percent to match the sizes. It took only a minute to do and works a treat.

Hi,
next pics are online... A takeout, ~4x enlarged: Date:2007-04-21 Distance: 2,442,013 km Filters: BL1 and CL2 Interesting overlapping craters now visible at the left side near the terminator in the northern hemisphere. Sadly the distance being so large once again - what a sight this angle of vision would have offered from say 400.000 km... Bye. |

Wow - those two make a beautiful stereo pair (but you have to place them diagonally).

It looks like the big landslide basin has a subdued inner ring, or am I imagining things?

And I can tell you the images of Iapetus taken on July 3 are in and ready for use.

Yep, the big basin is nicely visible -- and what's more, it's noticeably lighter in colour than the surrounding area.
That's got to have ramifications for some of the origin theories of Cassini Regio. |

So, could ejecta from the big southern basin have covered up a pre-existing dark equatorial band that originally bisected Roncevaux Terra? (Theory number 7,234.)
