Planetary Radio’s most frequent guest, Project Scientist Linda Spilker, returns with another update on the Cassini mission that is approaching its grand finale. Senior editor Emily Lakdawalla has a special announcement. Humans on Mars by 2033? Bill Nye sees a glimmer of hope. Our solar system’s biggest volcano is on the Red Planet. How big? Bruce and Mat share some dimensions on What’s Up.

Daphnis in the Keeler Gap
Cassini was able to capture its closest-ever view of Daphnis toward the end of its mission, during its F-ring orbit phase, when it passed between the F and G rings once per orbit. Daphnis is only about 8 kilometers across.

Always a feast to have Mrs. Spilker on, and my favourite mission as a topic. Yet still: noooooooooooo.... ':( Send fuel. Send a Light Sail. Send someone. At least make Cassini II
