Cassini's orbits are now averaging 8-9 days apiece as the end of the prime mission approaches, and according to information posted on this forum, Cassini approaches within 75,000km of various 'rock' satellites EIGHTEEN times in the next ten weeks.
These flybys include the closest remaining encounters with Daphnis, Prometheus, Pandora, Epimetheus, Janus, and Pallene (all of these sub-30,000km). Many close moon-encounters fall during Saturn eclipse, and there are many competing experiments around periapse, but hopefully there will be some planned ISS observations of these small moons at or around closest-approach... ![]() ![]() |

Hi Andrew, this is a view of Janus I've been looking forward to. I agree about the calibre of contributors here. Some of the very best image-smiths showcase their work on this site for all to enjoy.
This image though is Janus in sunlight just prior to eclipse - any image obtained by light due to Saturnshine would have been significantly degraded in terms of quality, and I don't think that there is enough light bouncing off adjacent moons to register in Cassini's optics during eclipse. (see versions of Helene posted in this section) My own attempts to clean up this image owe more to artistic interpretation than anything else, and fall well short of standards here, so i've avoided posting them - I need some practice.... ![]() |
