Unmanned Spaceflight.com _ Cassini general discussion and science results _ Cassini Imaging - More Agressive?

Posted by: tedstryk Feb 28 2005, 01:04 AM

It seems that starting with T3, Cassini was much more agressive in imaging available targets. It seemed to turn more to image more moons. Am I imagining this, or was Cassini being ultraconservative when it still had Huygens?

I think it has to do with its Lower orbit.

well...it is true that when it still had Huygens, its moment of inertia was much higher and thus the turn rates were lower.

I hope Cassini had her cameras pointed at Titan on March 1, 22:35 UT:

Oh yes!

Very nice.

I think Sunspot would like an image of Titan with Saturn on the background. wink.gif

I think that the "string of pearls" imagery where several moons are seen in a row along the line of Saturn's rings is very beautiful.

I am actually surprised at how visible the rings are edge-on, given how thin they are. I would have expected them to disappear against the background of Saturn altogether. Perhaps they are not precisely edge-on?

They pretty clearly are not completely edge-on in those photos -- there are some where the width of the thin triangle of visible ring is a bit wider than others. (Which is hardly surprising.)

The interesting question I myself haven't seen answered yet is whether the edge-on photos featuring Prometheus and Pandora -- which show a clear gap between the thin illuminated line of the F Ring and the thin illuminated line of the other rings -- are just due to this viewing-angle effect, or whether they're showing actual out-of-plane tilting or warping of the F Ring. (My guess is the latter. In one of those photos, Pandora, which of course is outside the F Ring, seems to be BETWEEN the plane of the F Ring and the plane of the other rings.)
