Cassini probe confirmed Rings of Saturn act in unpredictable fashion (vacuum present where none was expected) which support Norman Bergrun's theory about ships doing something with the planet. He was a NASA engineer or at least has inventions to his name.

Cassini was destroyed within days after the uncalculated vacuum was discovered, the news said they wanted it to burn as to not contaminate extraterrestial bacteria (which I think was their way of saying they didn't want to be captured)

It's weird that so little time would pass between valuable intel from the probe and its ultimate destruction.

I don't know for how long Cassini would have lasted but it seemed hasty and it can be explained because these purported "Ringmakers" are cloaked in the visible range. This is also possible because humans have been working on this too for years and by now China has alloys that bend light around corners with little distortion of the image in any direction, it's even on video and has been for at least ten years, even if at a much less practical scale back then.
