From Looking Ahead: Rev153: Sep 3 - Sep 22 '11
A lot going on this revolution: Sixty-one ISS observations are planned for Rev153, the majority designed to monitor cloud systems in Saturn's atmosphere. 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. -------------------- |

From Looking Ahead Rev 153:
ISS begins its observations for Rev153 two days after apoapse with a satellite search observation. ISS will image the L5 Lagrange point region of the moon Iapetus, about 60 degrees behind of the icy satellite in its orbit. This type of Lagrange point has been found to host Trojan moons before in the Saturn system. Cassini discovered the L5 Trojan moon of Dione now named Polydeuces in 2004. Another, Calypso, shares the same orbit as Tethys but lies 60 degrees behind it. This satellite search observation could detect objects as small as 90 meters near Iapetus' L5 point. Similar observations will be acquired of the L5 regions for Rhea and Dione on September 21 and 22, respectively. What would be great is if someone made the images into a slow movie to see if any faint slowly moving object can be seen Lots of good things to see in Rev153 (from thread I started a few days back) Sixty-one ISS observations are planned for Rev153, the majority designed to monitor cloud systems in Saturn's atmosphere.
