Saturn's a difficult thing to orbit. The rings mean you either orbit a fair way out with the moons where your orbit will take ages to decay, or passing so close to the planet you're practically scraping the atmosphere anyway meaning your orbit will decay very quickly. Plus, there's so many bits of rock and such floating around Saturn that any close orbit would quickly be perturbed and the spacecraft could end up anywhere.

Besides, it's power source will run out pretty soon as well. Much better for it to get some final data to us about the upper atmosphere of Saturn, rather than having to wait for a later mission to get that data. If we want a souvenir when we get there we call always dig out the Huygens probe.

The problem is that an orbit isn' stable. It always suffers from slight changes in gravity because of the Sun and Saturn, also Saturn has billions of moons. So when a big moon floats by it pulls the Cassini a bit to himself. resulting in a slight change in the orbit. after years it could be so that the orbit isn't stable at all and could crash in one of the moons nearby and there is a chance that there is life on that moon. If the Cassini hits that moon it could kill all life containing it and that would be a shame.

Man Cassini was fucking amazing. Aesthetically, too, the images it made were absolutely amazing. Unlike Juno for example which was pretty disappointing in that regard as of yet. I mean, even Hubble produces more appealing images and it's not even there.

Titan's the only other world in the Solar System with rivers and rain. It's a shame we know so little about it.

>This image, taken with the radar on the Cassini spacecraft, shows just how similar the features in Titan’s surface are to Earth’s landforms.
>Aside from Earth, Titan is the only other body where we have found evidence of active erosion on a large scale. There are seas, lakes and rivers filled with liquid hydrocarbons – mainly methane and some ethane – that etch the moon’s surface, in much the same way water erodes Earth’s.
>A striking example is Vid Flumina, the Nile-like, branching river system visible on the upper-left quadrant of the image. The river, in the moon’s north polar region, flows into Ligeia Mare, a methane-rich sea that appears as a dark patch on the right side of the image.
>Researchers in Italy and the US analysed Cassini radar observations from May 2013 and recently revealed that the narrow channels that branch off Vid Flumina are deep, steep-sided canyons filled with flowing hydrocarbons.
>The channels are a little less than a kilometre wide, up to 570 m deep and with slopes steeper than 40º. This suggests they have been sculpted by liquid methane, flowing into the main Vid Flumina river, that has persistently eroded the canyon walls – a geological process reminiscent of the carving of river gorges on our planet.
>The study is the first direct evidence of deeply entrenched, methane-flooded channels on Titan. Finding out how they formed provides insights into the moon’s origin and evolution and could help understand similar geological processes on Earth.
>The Cassini–Huygens radar team is hoping to observe the Ligeia Mare and Vid Flumina region again in April 2017, during Cassini’s final approach to Titan. The mission is a cooperation between NASA, ESA and Italy’s ASI space agency.
