Join us at JPL and Caltech on the bittersweet morning the Cassini spacecraft plunged into Saturn. We’ll hear from many of the spectacular mission’s leaders, including Jim Green, John Grunsfeld, Ralph Lorenz, Bob Pappalardo, Earl Maize, Linda Spilker and Julie Webster. Bill Nye salutes the mission team and calls for continued exploration of space. The Cassini theme continues as Bruce Betts reveals What’s Up.
