"We selected a combination of objectives thanks to the adequate situation of Cassini's instruments, which would enable us to point cameras to Saturn, magnetometer boom at Rhea and radar set at Titan since these images, data and sensing beams could help understand better the complex chemical processes us that are taking place in Titan, a possible electromagnetic phenomena in Rhea,(could it have invisible rings as suggested in NASA videos?) and send penetrating radar beams at Titan, and help us study the internal structure of these moons, since some scientists think that underground oceans of dissolved ammoniac water are at 100 kilometers down,under the surface exists, and perhaps another one of hydrocarbons.

Titan is the unique moon of the Solar System that counts on a significant atmosphere, reason for which is interesting its scientific study, its made up mainly of nitrogen and is rich in methane and other hydrocarbons. Its chemical composition assumes similar properties to primitive Earth atmosphere in prebiotic times. Temperatures near 90K (-179.45 °C) must have preserved surroundings very similar to the one of primitive Earth.

The atmosphere of Titan is 94 percent nitrogen and is unique in rich nitrogen in the Solar System aside from our own Earth planet, with significant signs of methane, etane, diacetilen, metilacetilen, cianoacetilen, acetylene, propane, along with carbonic anhydride, carbon monoxide, hydrogen cyanogen, cyanide and helium.

Titan is an extraordinarily abundant organic compound world. Probably the liquid hydrocarbon content of this moon in the form of seas and Lakes is hundreds of times superior to the one of all the reserves of natural Earth petroleum and gas?

The partial pressure of the methane and clouds cause liquid methane storms in Titan that unload important methane precipitations which arrives at the surface producing altogether about 50 L/m from annual precipitation.

Another point that makes the observation interesting of Titan basing us on the results of the Huygens sounding, is the possibility of life existence since its atmosphere is rich in methane. Nevertheless, there is a disparity in the density of hydrogen. Then it seems that the hydrogen disappears in the surface of Titan because of some unknown mechanism. Could the peculiarity of this phenomenon, and the necessity of a methane source indicate the possible existence of life? And last but not least, we would point the main camera to Saturn, to keep on studying its storm systems and its rotation speed!!"
