26 Nov. Close Flyby (500 km.) of Rhea...(Size: 1538 km.)
27 Nov. Distant Flyby (108,000 km.) of Enceladus...(Size: 512 x 494 x 490 km.) 27 Nov. Distant Flyby (86,000 km.) of Helene...(Size: 36 x 32 x 30 km.) This should be interesting...  Can anybody give a bit more information on the upcoming flybys??? Is this the best image of Helene that we have??? Vojager 2 - distance :341000 km)

Is Cassini set to do hi-res ISS imaging of Rhea? I was looking at the pointing info using the CK kernel and it seems that the ISS pallet is pointed away from Rhea during the closest approach (from ~50,000 km inbound to ~50,000 km outbound). The RADAR doesn't seem to be pointed that way either during that interval. So what is the plan for imaging at Rhea?
Could be a problem with my software, but here's an animation (7MB MPG) showing (via a yellow dot) when and where during the flyby the NAC is pointed: Rhea/NAC movie On edit: I spoke too soon--it went by so fast I missed it: the NAC sweeps across Rhea's latitude 10 degrees south (approx.) in a straight line right at the time of closest approach, lasting only 4-5 minutes. Here's an animation showing the camera boresight as a yellow dot: Rhea NAC -- closest approach -------------------- |

Thanks! To follow up on jmknapp's comments, here is what that document has to say about ISS observations: "For ISS, this Rhea flyby provides an opportunity to capture the best images of the wispy terrain and to obtain high-resolution images of a relatively fresh, bright crater on the leading hemisphere. ISS will perform mosaics on the inbound leg (178,000-54,000 km) for regional mapping. At closest-approach, ISS will capture the highest-ever resolution images of Rhea as the moon passes through the field-of-view of the camera." Note the comment about the ray crater being imaged at very high resolution. -------------------- &@^^!% Jim! I'm a geologist, not a physicist!
