This would make such a cool conspiracy/sf plot
The Cassini probe is really a plot to "stellate" Saturn. The Free Masons and other Illuminati in on the plot will use Cassini's plutonium fuel to trigger a fission explosion. This, in turn, will create a fusion reaction that will ignite Saturn into a small sun.
the motivation appears to be terraforming Saturn's moons, particularly Titan. I expect that is where the Illuminati intend to flee when Earth's resources are used up.
I read it on the internet so it must be true.http://www.rinf.com/news/nov05/lucifer-project.html
