there is a least information about cassini mission news by these days eighter in the newspapers or in science magzines. always information reach to the common people like me only after getting information through such means.

as there are huge activities on the saturn about the great tycoons on the surface which result into the saturation of the dust apart with the globe of saturn! may be the cassini mission having all the possible answers about its rings.

or may be the dust is rotating the saturn in circle in the form of clouds!

I really don't know the realities thereon. when I went to one old man who has given me the information that saturn is a uncommon astronomical object in the sky and its folds of realities cannot be open easily, so such cassini like mission can only open the folds for the world, he admitted that the current science has that capability to open the secrets of the universe, but he was mostly relent upon the 'possibilities thereon', and people has that ability to show some different picture to impress.

scientifically I cannot give the answer about 'how the rings were formed', but roughly assuming that the rings are eighter the dust particles, stones revolving along with the saturn globe, or the rings are just formed during the original formation of that globe along with the ring, but if we say that in bigbang items thrown away in the universe and fall at a huge distance, along with the ring this is not possible, may be the rings are formed after a long gap of saturn's birth !
