Your post, Matt, reminds me of this IMAX video compiled (in 2011) from Cassini's thousands of images when approachng Saturn in 2004:

The sound track is Samuel Barber's
Adagio for Strings, often claimed by some to be the saddest music ever written (also used for a program on 9/11 recall) and somehow a poignantly appropriate piece to play for Cassini's farewell.
Cheers,
Richard
