" Cassini has made many interesting maneuvers so for and is about to choose an observation for upcoming experiment. The planet Saturn is a spectacular one among all other planets in our solar system. The rings add more flavor to its beauty. These sings are categorized into, namely A, B, C, D, E, F, G rings. These rings have many unsolved mysteries and discoveries inside them, to solve them Cassini's wide angle camera shot has to be cast on Saturn's ring.

The rings when observed deeply it is nothing but combination of millions and millions of orbiting particles and many moons in its rings itself, also they are combination of water from eruptions on Enceladus, be sides has many icy and rocky materials, which are sized from size of sugar particles to the size of a large house.

The rings probably are formed due to one or more moons breaking down due to their collisions with comets or meteorites. We observe differences in their movement around Saturn and also can determine from their orbits. Changes associated with Saturn can also be noted and their influence on the rings is determined. We may find whether, Magnetic flux or fields created at different instants by Saturn, effects the path of materials in the rings. The variation of gravitational pull from place to place may also be the reason for formation of spokes, which can be found by camera shots sent by Cassini.

When observations are made on rings, many collisions may occur and we will have many observations to be carried out on the impact of collision on the neighboring particles and on the nearest moon etc. We may come across new material particles which may contribute for dust or water or any other materials in the rings system of Saturn. The composition of dust particles is found and can study belt /zone structure variations in ammonia concentration. We can observe the impact of cyclones or storms, generated on Saturn, on the rings and its nearest particles. We may also note whether the dust particles form the dust storms escape Saturn's gravity and reach the rings. We can also determine temperature field, cloud properties and composition of Saturn's atmosphere as well.

There is a probability of finding a new moon of Saturn on which there are possibilities for existence of life like conditions. It would reveal the reality of how the spokes are formed. If we study the relationship and variations between ionosphere and the planets magnetic field and their influence on the particles of the rings. We can observe whether solar eclipses take place due to different sized particles of the rings. If any occurs we may take out many observations at equinox to find answer to many mysteries, which may also help us to determine temperature gradient and unknown sub cloud longitudinal structures at equator to pole. This way it is best to choose Saturn's rings as our target for observation. "
