There were RTGs on the Apollo missions as well. RTGs do not pose a danger. I am looking forward to this mission. :-)

It's already returning some really spectacular pics.

I was one of the people "Freeping" the anti-Cassini folks in front of the White House back before it launched. It's very gratifying to see it so close to orbit insertion.

Somewhere out there, a DVD with 600,000 scanned images of signatures, has my signature and my two youngest kids. The youngest was in kindergarten when JPL accepted the signed cards, his signed in crayon -- now he is entering high school. So very cool.
