Thanks for the link, great overview. I think this ominous line rings particularly dark and gruesome, "Cassini reconfigures from an orbiter to an atmospheric probe".
The spacecraft is at Saturn. During its final time, it will not have the transmission speed to send pictures, though it will send atmospheric measurements until the very end.
It could, but the Deep Space Network is the bottleneck 100kbit speeds and hours round trip makes getting the data difficult in best conditions, eg. orbiting out by titan
