*psst* I think you missed my reference. While the quote may have been the classic Star Wars line, the pic and slashies are a different fandom...see if you can figure it out, you welnitz.

It's coincidental, because I just started watching Farscape for the first time on Netflix last week (I'm 6 episodes in so far).  I didn't miss your reference, I was just noting the excessive quotations joke, or did you miss my reference?

A. Ring material is largely confined to the orbital plane the ring occupies.

B. Though planetary ring systems look rather solid at a distance of several million miles/kilometers, there is actually more empty space there than matter.

Fun fact, several spacecraft have passed through Saturn's ring plane, including Pioneer 11, Voyagers I and II, and most recently, Cassini. Pioneer 11 had a close call with Epimetheus, a moon just discovered the day before, which was the only notable "close call" a probe has had in the area.

Meh.  It's either a streetlight, or another one of those space alien vehicles after launch.

Earth can't have rings as long as the moon is there.

The more you know.

Lets talk frankly about internal cleanliness: A. Ring material is largely confined to the orbital plane the ring occupies.

B. Though planetary ring systems look rather solid at a distance of several million miles/kilometers, there is actually more empty space there than matter.

A.) Most geosynchronous satellites launched from CONUS are launched from 28.5 degrees inclination. Ergo they would pass through the plane of the rings twice every orbit. In fact everything launched would have to pass through the plane of the rings twice every orbit unless they were in the plane of the rings, which is even more risky.

B.) The space junk around Earth is not visible to the naked eye, yet it is fully of deadly debris that must be tracked. Can you imagine how much crap it would take to make them visible? Would they be less or more dangerous?

It's Saturn's one weird trick to lose mass from the ring around your middle.

Being in the plane of the rings isn't risky at all.  Your relative velocity with the piece of junk 50 meters away is zero.

I read it as popped out but thought it SHOULD be pooped out.

FrancoFile: Being in the plane of the rings isn't risky at all. Your relative velocity with the piece of junk 50 meters away is zero.


Phasing and differences in perigee can cause substantial relative velocity differences creating plenty of objects that are traveling plenty fast relative to you, given the number of particles it is also not practical to track them. Being in the same plane increases your exposure time to the debris field. Risk of impact is related to exposure time, more is worse. So being in the plane is worse than passing through it twice an orbit. The energy of the intersecting planes will be higher, but the probability of collision is much less.

I didn't write the book on MM/OD analysis, but I have read it. Here is a copy:

I know all that.

But a well-behaved ring system with shepherd moons is as close to a circular orbit as you're ever going to find.
It's getting IN to that orbital position where you have the trouble.

You know, I thought about that on my ride home. I really shouldn't try and craft an intelligent post while on the phone with a client... I always seem to overlook the obvious.

It would be awesome if over the next couple years it collected all the material in the rings and formed a bigger moon.

Fair enough, my experience is in LEO and human beings, so when I try to extrapolate that to a more serine environment like that around Saturn it is hard to lose my fear of a retrograde paint flake destroying my spacecraft I have so carefully designed. But you are right, getting there is the hard part and the process of getting their causes local gravitational perturbations that would make me fearful of staying there.

Supposedly, the next game is supposed to be a little less of a downer, but yeah. DeadSpace 3's story turned me off to that universe. It's worse than a Lovecraft story for crapsack world.
