I have noticed that the January 1, 2007 Cassini PDS release is already available, see http://pds-imaging.jpl.nasa.gov/data/cassi...assini_orbiter/
I haven't downloaded all of the imaging data and I'm just beginning to digest what I already have but there are some beautiful images of Enceladus' plumes and satellite mutual events, images of the G and D rings and interesting images of Saturn's nightside and fairly good Iapetus images. Radar and VIMS is also available. All in all a nice 'Christmas gift'  .

Wow, I assumed the reaction wheel figures were high but these are quite substantial indeed. Is the time difference primarily due to different mass distribution along each axis? I can't seem to dig up a schematic showing the orientation of principal axes, but this would suggest the Z axis running along the length of the s/c, parallel with HGA boresight and the X axis being the most inert of them, orthogonal to the plane in which HGA boresight and magnetometer boom lie?
How do these figures change with propellant depletion (if at all)? Optimizing slew maneuvers is no doubt one of the (many) factors in increasing useful observation times... -------------------- |
