In its final year, Cassini plunged where no spacecraft had plunged before, down in the space between Saturn and its rings. Again and again it dove, for a total of 22 orbits.

It is, they say, not only new evidence that Saturn’s rings are much younger than the planet, but also a window into the way planets form in the giant rings of dust and debris that circle newborn stars.
