Cassini will make its final close flyby of Saturn‘s moon Titan on April 21
They're going to fly between the planet and it's rings - but how? I was watching a show on Voyager 1 where they had originally thought about doing the same, but were glad they didn't. When Voyager got close enough to image the rings, there was quite a bit of debris between the planet and the rings. Apparently, it was enough to ensure the destruction of the spacecraft. Do they now know enough about that debris field, and now have accurate enough "control" (calculated by astrodynamics), to avoid a collision?
