A little belatedly (to post here- the article's been up for a week or two), looking ahead for this revolution (now half complete) here
WAC enceladus from 185km - great detail! Some shots of tethys too - some are very smeared - spacecraft slewing during shuttering perhaps?? Also some enceladan plumes Great stuff! |

If distance to the terrain in those images is really 185 km, then ~11 m/pix for WAC image and ~1.1 m/pix for NAC image. So theoretically smallest visible details could be only 2.2 meters wide, but realistically, after some processing and for raw file, my guess is, that details (with high contrast) with size about 6 to 12 meters could be recognizable (some boulders, I presume).
Which is not bad result, maybe it's even record for Enceladus. If my memory is right, then best image to date had resolution ~4 m/pix (and this image was smeared too, but not so badly), so details around 8 to 10 meters were recognizable. -------------------- |
