Wasn't Cassini the spacecraft that brought out New Age protesters and some well-known supersymmetry physicists to say that we were in danger of poisoning our planet forever if we launched?

Yup, it's the same spacecraft. Early on in the mission, it flew by Earth on its way to Jupiter, and the environuts went wild, because of the extremely small chance that the Earth's gravity would pull it back in. Watch the same people go bonkers when NASA starts its launch plans for the Jupiter Icy Moons Orbiter, which will have a small nuclear reactor on board, which won't be activated until it is a safe distance away from the Earth.
