I support the extension of Cassini as well as the continued mission for the Mars Rovers. But costs need to be justified - especially in hard economic times. And please, no one compare to this to Pentagon no-bid contract (enough said).

And after thinking, of course Cassini and the Mars Rovers not missions that you can just listen. They require active work, nagivating (the Saturn system may be the most complex network of bodies in the system!) and decide What to Look at Next. But maybe after the data is collected, we can get help from volunteer or the ESA and Italian space agency who might be just as invested in this as we are.

Of course, in all cases, whenever we spend BILLIONS to send probes out the far and weird, it would be a crime not to spend millions to exploit them as much as possible, until contact is lost or they become only good for a final hard landing scenario.
