The spacecraft also will encounter a number of Saturn's moons, including Titan, Pallene, Tethys, Enceladus, and Hyperion, for which ISS will acquiring imaging. ISS will image the L5 Lagrange point (60 degrees behind satellite) regions of the moons Iapetus, Rhea and Dione to see if they have Trojan’s like Dione/Polydeuces and Tethys/Calypso. Titan encounter Sept 12. CIRS, VIMS, UVIS, INMS, CAPS, ISS Imaging Enceladus polar plume from night side at 42,224 km and two mosaics of sub-Saturn hemisphere. Sept 13 Imaging Tethys from 300,00 km Sept 13 Image Pallene from 25,960 km (38x26 pixels at that distance as only 3.6 x 2.5 miles) Sept 13 Image Hyperion from 58,015 km—a little further than last month. Sept 16. Color image of Tethys passing in front of Titan's south polar hazes. Sep 16. Mutual events Enceladus in front of Titan with Rings and Pandora in background Sept 17. -------------------- Floyd

I badly want to color-compose even a still from the last sequence with Titan, Dione, Pandora, and Pan (did you notice Pan zipping around the corner?) but I'm afraid it's beyond my skill. -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.

I didn't notice that one! And it doesn't seem to show up in the Saturn Viewer either, at least not at the same scale:

But if I widen the view to the WAC FOV, you can see Methone. I wonder if it could be Methone, not quite showing up in the spot it was predicted to? Jason??
