Hi guys, do you have resources for this. I appreciate you can direct me in there may be some links. Thanks, I appreciate it.

NASA has made a very nifty little program available, called NASA's Eyes. Check it out.

Yeah, I've been there. But, so unfortunate to get orbital parameter details, like its measurements.

Cassini's orbital elements are constantly changing. How deep do you want to dive down that rabbit hole because it's effing deep. Here's a start (pdf), just to give you an idea what you're asking for. Cassini is actively manoeuvring. It's not just a passive orbit.

If you're desperate, contact JPL. They're in charge of the mission.

Cassini's orbital profile is complex and has all kinds of inputs. It has to take into account the orbits of all Saturn's moons, Saturn itself of course, Jupiter's (yes, Jupiter's also) and the Sun's contributions. Plus the craft is actively making orbital corrections. You couldn't ask for a thornier problem.

How exact do you have to be in your calculations? Are you making an animation? It is one thing to approximate Cassini's orbits for, say, animation purposes, and quite another to actually navigate the craft inside the rings. In the latter case extreme precision is required. Do you need such precision? What are you trying to accomplish?

Here is a summary of Cassini's final 22 orbits. Perhaps you can approximate from what you find here.

I guess it's no longer a gas giant now that it's 'plus one' spacecraft.

Anybody care to speculate about the hexagonal vortex at the pole on Saturn? When are learning about honey bees they explain it as being the strongest form so on. But why here and how? It's just not right I tell you.

I'd post a pic and some spec's, but I'm mobile and spacing out about it.. again.

.. I love how it begins with "explanations" and "one hypothesis"

Otherwise I'll give it a go in terms of plausibility.

I'd like one of those 'swirling spheres of liquid'.. kinda like a lava lamp+.

How close an analog is a sphere of liquid is in comparison to Saturn?

Does it need to be?

Guess not.

.. I was thinking giant space bee's..
